CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This PCT Application claims the benefit under 35 U.S.C. § 119(e) of United States Patent Application Serial No. 63/319,615 filed on March 14, 2022, entitled MODULAR AND ADJUSTABLE LIGHTING APPARATUS AND METHODS, and all of whose entire disclosure is incorporated by reference herein.

BACKGROUND OF THE INVENTION

1. FIELD OF INVENTION

[0002] This invention relates to modular electrical apparatuses and methods and, more particularly, to modular and adjustable lighting apparatuses and methods.

2. DESCRIPTION OF RELATED ART

[0003] When permanently installed lighting fixtures need to be replaced or upgraded, many fixtures, especially in commercial buildings, include attachment points or wires that are inaccessible to the user after installation. Building lighting and controls include a plurality of wires that must be handled with care to avoid electrical hazards. When replacing lighting fixtures, these wires must often be disconnected, reconnected, and occasionally soldered to safely replace the fixture.

[0004] For example, with a suspended ceiling having a plenum space, accessing the power supply of the light fixture to facilitate removal may require removal of the entire ceiling structure if the fixture’s power supply is within the plenum space. As a further example, traditional light-emitting diode (LED) fixtures are typically replaced by removing the holder used to house the LED module. These holders are usually coupled to wires with inline connectors within the heat sink or above the heat sink within the ceiling, making disconnection of the wires difficult. As the average power supply manufacturer in the general illumination market only supplies a five-year warranty, the need for frequent replacement and the difficulty of accessing these attachment points or electrical wiring can make replacement of these fixtures complicated, time-consuming, and expensive.

[0005] Therefore, there remains a need to develop lighting apparatus and methods permitting easy replacement of light fixtures with minimal disturbance to the light fixture’s surroundings. The invention disclosed herein permits a manufacturer and end user to assemble or replace the LED module without removing wires from the LED module holder, cutting soldered wires, preparing thermal interface material for adequate surface connection between a new replacement LED and heat sink, or disposing of entire fixture, including the LED, heatsink, and optical assembly at end of life or in need of repair or service.

[0006] All references cited herein are incorporated herein by reference in their entireties.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION [0043] The invention includes a modular lighting apparatus, wherein the apparatus includes: a core mounting unit; an electrical conductor comprising a multi-port connector on one end and a universal connector on the other end; a heat sink; and a media holder, wherein the media holder includes all of the optical and electronic devices for generating the light output. In certain examples, the media holder also includes all non-visible light accessories. Among other things, the media holder includes a media holder base, a media holder cover, a transfer printed circuit board (PCB), an optical assembly, and a light source. In certain examples, the media holder also includes light accessories. As such, the media holder provides a “modular design” in that it is a replaceable unit that can be easily disconnected and a new media holder installed in its place as discussed below. There is no need to “disconnect any wires or connectors” in order to remove the media holder and then install a new one.

[0044] The core mounting unit serves as an attachment point for the majority of the apparatus to a surface, such as a ceiling. In certain examples, the core mounting unit is manufactured from a metal such as aluminum, steel, iron, and copper. In other examples, the mounting unit is manufactured from an alloy such as stainless steel and brass. In further examples, the mounting unit is manufactured from ceramic. In still further examples, the mounting unit is manufactured from a plastic, such as polyvinyl chloride, polyetherimide, polybenzimidazole, polycarbonate, and acrylonitrile butadiene styrene.

[0045] The media holder couples to the base of the heat sink by aligning apertures/cut- outs in the edge of the media holder base (Fig. 3) via positional alignment to the fasteners (e.g., screws) that protrude downward from the base of the heat sink (Figs. 2, 2A). This alignment and rotation acts as a “twist and lock” feature to releasably secure the media holder to the heat sink (see Figs. 6A-6B). One of the key features of the present invention is that the transfer PCB Board (Fig. 3) is what acts as the interface for conveying power and signal, signal conditioning, etc., to the light source (e.g., LED board) and optional light source accessories when the transfer PCB Board and the light source (e.g., chip-on-board (COB), dual-in-line package (DIP), surface-mounted device (SMD), ceramic discharge metal halide (CDM), laser, and other signal wavelength or emitting or receiving components) are coupled via edge connectors at the factory. The end user, however, need not concern himself/herself with this interface. Although not clearly shown, the upper surface of the transfer PCB Board includes positive and negative electrical contacts. When the media holder is assembled and brought into alignment with fasteners in the heat sink base, and then slightly rotated, the positive and negative contacts on the upper surface of the transfer PCB Board (Fig. 4A) are exposed through the window (Fig. 3) and align and contact with corresponding positive and negative contacts (Fig. 2A) on the multi-port connector, thereby immediately energizing the light source in the media holder from the power supply. In particular, when the end user slightly rotates the media holder, the corresponding positive contacts are connected first, followed by the corresponding negative contacts, at which time power energizes the light device. As thus can be appreciated, there are no wires or connectors that are being disconnected and then reconnected. All that is required is the engagement and slight rotation of the media holder unit at the base of the heat sink via a “twist and lock” motion.

[0046] In other examples using the multi-port connector, the apparatus is able to function even if all ports are not filled. In additional examples, the port connector is a universal port assembly.

[0047] As mentioned previously, the media holder further includes the transfer PCB, a light source, and an optical assembly. In certain examples, the optical assembly includes a lens. In certain examples, the light source includes an LED board. In additional examples, the light source is selected from the group including an incandescent bulb, a compact florescent bulb, or a halogen bulb.

[0048] In certain examples, the transfer PCB is manufactured of a material with low thermal conductivity, such as Micanite.

[0049] As a nonlimiting example, the media holder additionally includes a securing structure, such as a chip-on-board (COB) holder, wherein the COB holder secures the transfer PCB in place within the media holder.

[0050] As shown most clearly in Figs. 4-6, the core mounting unit is pivotally-coupled to the heat sink by a joint, wherein the joint allows a user to adjust the positioning of the direction of the light exiting the lens of the optical assembly. In certain examples, the joint is selected from the group including but not limited to a hinge and ball-and-socket. In one non-limiting example, the apparatus uses a hinge joint, permitting the mounting unit to tilt at a 45-degree angle from the media holder and allowing the user to adjust the directionality of emitted light. It should be understood that when the invention is installed in a ceiling cavity (not shown) the heat sink is installed in a vertical orientation (viz., Fig. 6) and the core mounting unit, along with a light blocking shield, are able to pivot within a ceiling mounting unit to provide a desirable light output angle, and hence, the adjustability feature of the present invention.

[0051] As just mentioned, the apparatus may further include a light blocking shield, wherein the light blocking shield is positioned parallel to the axis of tilt and prevents misdirection of light above the lens.

[0052] The invention additionally includes a method of using the apparatus of the invention, including securing a mounting unit of the apparatus to a surface; coupling a media holder to the heat sink base in an easy twist and lock motion without having to disconnect any wire or connector; using the apparatus for the duration of the media holder’s lifetime; decoupling the media holder from the mounting unit by reversing the twist and lock motion; and replacing the media holder with a new media holder, wherein the coupling step includes aligning apertures/cut-outs in the edge of the media holder base (Fig. 3) to the fasteners (e.g., screws) that protrude downward from the base of the heat sink (Fig. 2).

[0053] Referring to the Figures, FIG. 1 shows a side view of the apparatus LF1. In this view, the mounting unit 108, light blocking shield 104, and heat sink 102 are shown. In certain examples, the apparatus uses a universal multi-port connector 118 (FIG. 2) to connect with the contacts 120 (FIG. 2A) of the transfer PCB 124 (FIG. 3). This example further uses a joint 106 in the form of a hinge to permit the use to tilt the angle of the light source to the desired location. The mounting unit 108 is also shown having a bezel trim 110, which is comparable to the bezel trim 4 shown in the embodiment LF2 in FIG. 14, to be discussed later. The optical assembly 112 is also shown, which directs light out of the fixture LF1. The optical assembly 112 is interchangeable with the media emission surface 3 c of FIG. 18. Further, it is understood that the heat sink 102 of the embodiment of the fixture LF1 shown in FIG. 1 is comparable with the heat sink 2 shown in FIG. 10 associated with another embodiment of the fixture LF2 of the invention.

[0054] FIG. 2 shows an exploded view of the heat sink 102 of the invention LF1. In this nonlimiting example, the apparatus includes a heat sink 102 with fasteners 134 (FIG. 6A) (e.g., screws) projecting downward and an electrical conductor comprising a multi-port connector 118 on one end and a universal connector 114 (FIGS. 2 and 5) on the other end. It should be understood that the multi-port connector 118 is positioned within a recess/cavity in the base of the heat sink and does not protrude downward as depicted in Fig. 2; this was shown this way only for clarity. Further, the universal connector 114 is configured to couple to a power supply to provide power as well as provide signal to accessory components, for example, motion sensors, wi-fi chips, test switches, Bluetooth®, and other accessories. It is also understood that in certain examples, the universal connector 114 is a 6-8 port connector. In other examples, the universal connector includes a different number of ports depending on the amount of power or signal to be transmitted (e.g., 12, 20, 30, etc.). Once the media holder 116 couples to the heat sink 102 via a twist and lock motion, the transfer PCB electrical contacts 120 (FIG. 2A) align with and are in electrical contact with corresponding electrical contacts of the multi-port connector 118 that provide power to the apparatus LF1.

[0055] FIG. 2A is an upward view of the multi-port connector 188 in the heat sink 102 base (FIG. 2) taken along line 200A-200A of Fig. 2. The plurality of PCB electrical contacts 120 are shown which align with and create electrical contact with the corresponding contacts of the multiport connection 118 shown in FIG. 2.

[0056] FIG. 2B is an inverted cross-sectional view of the heat sink 102 and media holder assembly 116. The interlocking portions of the heat sink 102 and media holder 116 are shown, permitting the twist-and-lock securing of the exemplary fixture LF1 (FIG. 1).

[0057] FIG. 2C is an inverted cross-sectional view of the heat sink 102 and media holder assembly 116 taken along line 200B-200B of Fig. 2B, showing the media holder 116 in a locked position.

[0058] FIG. 2D is a enlarged partial view of the 200C section of Fig. 2C of the inverted heat sink and media holder assembly. The optical assembly 112 is shown coupled within the media holder 116. In certain examples, the media holder 116 includes a COB holder 122 which in turn holds the LED chip-on-board (COB) secondary circuit board 126. The transfer PCB contacts 120 are also shown making contact with a surface of the multi-port connector 118.

[0059] FIG. 3 shows an exploded view of the media holder 116 of the invention LF1. The external structure of the media holder 116 includes a media holder cover 132 and a media holder base 128. In this example, the media holder 132 cover includes a cut-out for the lens of an optical assembly 112, and the media holder base 128 includes a cut-out window 130 permitting the positive/negative contacts 120 of the transfer PCB 124 to be exposed from within the structure. The media holder 116 additionally includes an optical assembly 112, which in this example incudes a lens and a lens housing. The media holder 116 optionally further includes a COB holder 122 coupled to the optical assembly 112, wherein the COB holder 122 is configured to secure a transfer PCB 124 and LED secondary circuit board 126 in place. In this example, the LED secondary circuit board 126 serves as a light source, by way of example only, where light is directed through the lens of the optical assembly 112.

[0060] FIG. 4 shows an additional exploded view of an example of the invention LF1 using a hinge joint 106. In this example, a light-blocking shield 104 is used and coupled to the apparatus LF1 to redirect light to the desired location. The hinge joint 10 permits a user to tilt the apparatus LF1, changing the directionality of the downlight. In certain examples, the hinge joint connects the mounting unit 108 to the heat sink 102. The universal connector 114, coupled to the heat sink 102, is also shown.

[0061] FIG. 4A is a view of the transfer PCB Board 124 electrical contacts 120 and LED board 126 of Fig. 4. The COB holder 122 is shown holding the transfer PCB 124 and LED secondary circuit board 126. The COB holder 122 is coupled within the media holder 116, which secures to the heat sink 102 (FIG. 2) with fasteners 134 in a twist-and-lock formation. [0062] FIG. 5 shows a side-view of an example of the invention LF1, wherein the apparatus LF1 is in a tilted position. In this example, the joint includes a hinge 106, wherein the hinge 106 permits the apparatus LF1 to tilt at an approximately 44 degree angle from the mounting unit 108. The light blocking shield 104 directs the light in the direction of the tilt by blocking any light from escaping upward and away from a user. It should be appreciated that the relative angle of the heat sink 102/media holder 116 to the core mounting unit 108 is depicted for clarity only; the heat sink 102/media holder 116 assembly are not pivoted within the ceiling cavity; rather, the heat sink 102/media holder 116 assembly is mounted vertically (see Fig. 6) and the core mounting unit 108 is then pivoted. The universal connector 114 is also shown coupled and extending from the heat sink 102. [0063] FIG. 6 shows an additional side view of an example of the invention LF1, wherein the apparatus LF1 is in a vertical position. In this example, the light blocking shield 104 fits flush with the heat sink 102, as the light emitted from the apparatus LF1 is directed vertically downward. While the mounting unit 108 is still coupled to the heat sink 102 via the hinge 106, the apparatus LF1 is not angled. It should be understood the hinge 106 is optional. In other examples, light directionality and intensity is altered with a light pod cap 3g (FIG. 18). The universal connector 114 is also visible.

[0064] FIG. 6A is an upward view of the media holder 116 (FIG. 5) as its media holder base element 128 is being registered with the fasteners 134 in the heat sink 102 (FIG. 6) base just before final coupling. In this nonlimiting example, the media holder base element 128 includes a plurality of recesses 136 which receive fasteners 134 when the media holder base 128 is twisted and locked into the heat sink 102 (FIG. 6).

[0065] FIG. 6B is also an upward view showing the media holder releasably secured to the heat sink 102 (FIG. 6) base with the electrical connection made. Here, the recesses 136 receive fasteners 134, allowing the media holder base element 128 to be secured to the heat sink 102 (FIG. 6).

[0066] FIG. 7 shows a perspective view of an exemplary mounting unit 108 and optical assembly 112 of the invention. In this example, the lens of the optical assembly 112 is visible. The optical assembly 112 sits within the mounting unit 108 to secure the optical assembly 112 in place. While the mounting unit 108 surrounds the lens of the optical assembly 112, however, it is noted that the mounting unit 108 does not cover the lens of the optical assembly 112 to minimize any obstruction of light exiting from the lens itself. In this example, the mounting unit 108 further includes mounting brackets 140, wherein the mounting brackets 140 assist in coupling the mounting unit 108 to a surface such as a ceiling. The media holder base 128 is also shown. The mounting unit 108 also includes an expandable unit 138 including a bezel trim 110. The expandable unit 138 permits adjustment of the optical assembly 112.

[0067] FIG. 8 shows a perspective view of the core mounting unit 108 and optical assembly 112 of the invention in a tilted or pivoted position. As discussed above, a joint 106 (FIG. 5) permits the core mounting unit 108 of the invention to tilt independently of the heat sink 102 (FIG. l)/media holder assembly 116, causing the lighting assembly LF1 (FIG 1) to tilt with it. As a result, this example shows the lens of the optical assembly 112 tilting from the mounting unit 108 at an angle. The recesses 136 within the mounting unit 108 are also shown which receive fasteners 134 (FIG. 6B) such as screws. [0068] FIG. 9 provides a flow chart of the key steps in assembling the apparatus of the present invention LF1. Furthermore, Fig. 9 also illustrates four, by way of example only, different embodiments of the present invention. In each example, the mounting unit 108 couples the heat sink 102 to a ceiling. Mounting unit 108 shapes vary in different examples and include round or square shapes with minimal or ornamental appearances. After the heat sink 102 is coupled to the mounting unit 108, the media holder 116 is twisted and locked into place. In certain examples, the invention also includes a bezel 110 surrounding the media holder 116. In further examples, an optional trim 142 is added for aesthetic purposes, wherein the trim 142 may be of various shapes, colors, materials, and sizes depending on the fixture and desired aesthetic.

[0069] FIG. 10 shows a perspective view of another exemplary embodiment LF2 of the invention. Within the core light assembly 1, the heat sink assembly 2 mounts to the light pod assembly 3 without the need for any tools or loose wires between the heat sink assembly 2 and the light pod assembly 3. The light pod assembly 3, once mated with the heat sink assembly 2, is secured in place via a mounting ring 3a which tightens the light pod assembly 3 onto the heat sink assembly 2. The mounting ring 3a mounts to the heat sink assembly 2 through mechanisms including but not limited to threaded rings, a twist-and-lock assembly, a clamp, a latch, magnets, screws, pins, or other similar mechanisms permitting the light pod 3 to be releasably secured to the heat sink 2, In preferably examples, the mounting ring 3a mounts to the heat sink assembly 2 without the need for tools (e.g., threaded ring, twist-and- lock assembly, etc.). Together, the heat sink assembly 2 and light pod assembly 3 are the core light assembly fixture LF2. When connected to power, the core light assembly fixture LF2 can be used in different configurations. For example, multiple core light assemblies LF2 could be arranged in a single fixture to create a different aesthetic. In the example shown in FIG. 10, one core light assembly LF2 is used in a single fixture. The heat sink assembly 2 dissipates the heat generated by the light source/ media emission surface 3c (FIG. 18) when powered on to keep the light assembly LF2 cool and maintain a long life. In different examples, the heat sink assembly 2 includes different materials, shapes, and sizes. For example, the heat sink assembly 2 may include an aluminum extrusion. The core light assembly LF2 can be designed to be accessible and serviceable from below the ceiling. Therefore, the core light assembly LF2 can be removed from below and fit through the ceiling opening.

[0070] FIG. 11 shows a top angle view of a fixture with the housing 6 around the heat sink 2 of the core light assembly 1 , wherein the housing 6 is open on one end for convection passive cooling. There is a cavity shown in the extruded aluminum heat sink 2, wherein the input 7a for the motherboard, power, and control signal is located. The input 7a is mounted to the inside wall of the housing 6. There is an output 8a from the mother/daughter card that sends signal and power to the light pod 3 (FIG. 10). In certain examples, the signal and power is sent through transfer board 9 (FIG. 14). In examples where the fixture LF2 (FIG. 10) does not generate heat in close proximity to the motherboard 7 (FIG. 15) or if heat is otherwise diverted from the motherboard 7, the motherboard 7/daughter card 8 (FIG. 13) assembly is mounted directly to the transfer board 9 (FIG. 20). In other examples, the motherboard 7 (FIG. 15) can include the transfer board 9 (FIG. 20), wherein at least a portion of the motherboard 7/ daughter card 8 assembly is located directly in the housing 6 or in the mounting supporting the light pod 3 (FIG. 10). The nonlimiting examples also shows a mounting collar 5 surrounding the light pod 3, wherein the mounting collar 5 is a flanged collar for mounting the fixture LF2. Other examples of mounting collars 5 for different ceiling types include but are not limited to gypsum or plaster collars, mud-in-ring collars, millwork collars, and stone collars.

[0071] FIG. 12 shows the transfer board 9 within the heat sink 2 of the core light assembly 1. The housing mechanical component 6b surrounds the heatsink 2 and further includes an open housing mechanical component 6a to permit passive cooling of the fixture. The transfer board 9 receives power and signal from the mother/daughter control board 7 (FIG. 13). The motherboard, power, and control input 7a is shown, wherein a mother card 7 (FIG. 13) is inserted into the input 7a in a nonremovable configuration, permitting input from the control board 7 to be output to the light pod 3. In certain examples, the transfer board 9 includes components including but not limited to a thermal switch, connectors, and/or other components such as an occupancy sensor, and battery test switch.

[0072] FIG. 13 shows an exploded view of an exemplary fixture LF2. The housing (6a, 6b) includes the housing mechanical component 6a surrounding the heat sink 2 and is coupled to housing portion 6b. Housing mechanical component 6b includes an input 7a (FIG. 12) into which the mother card 7 can be inserted into the input 7a. A daughter card 8 that is interchangeable and removable is also included in the fixture LF2, wherein the daughter card 8 provides power and control of LED light sources, such as RGBW (red + green + blue + white), RGBWW (red + green + blue + white + warm white), tunable color, tunable white, other dynamic light sources, and other components such as sensors. Examples of control methods employed by the daughter card 8 include but are not limited to digital multiplex (DMX), 0-1 OV controls, antenna, on-demand lighting and wireless controls for light sources including RGBW, RGBWW, tunable color, tunable white, and other dynamic light sources. [0073] FIG. 14 shows a cross-sectional view of optional housing mechanical component 6b of an example of the fixture LF2, wherein the optional housing mechanical component is surrounding the core light assembly 1 . As shown, the housing mechanical component 6b surrounds the heat sink 2. The heat sink 2 includes a transfer board 9 for receiving power and signals from the mother/daughter control board 7 (FIG. 13). The housing mechanical component 6b also contains cavities for the motherboard control input 7a (or other type of power supply and/or signal control component) and output 8a for the mother/daughter card 8 (FIG. 15). The heat sink 2 is coupled to the light pod 3. In this example, the light pod has a bezel trim 4. The housing mechanical component 6b is then coupled to the ceiling mounting collar 5.

[0074] FIG. 15 shows a side, partially exploded view of an additional example of the fixture LF2 of the invention. In this example, the fixture LF2 also includes a mechanical guide 10 permitting the angle of the fixture and direction of light to be adjusted. In other examples, the fixture does not include a mechanical guide 10. The example also shows the motherboard 7 with control input 7a and removable daughter card 8. In certain examples, the motherboard 7 and daughter card 8 are mounted to the inside of the housing 6b (FIG. 14). In other examples, a housing 6b is not used. This particular example also shows the heat sink 2 mounted to the light pod 3, wherein the light pod 3 is coupled to a ceiling mounting collar 5. [0075] FIG. 16 shows a perspective view of another example of the fixture LF2 of the invention. Here, the mounting ring 3a is shown more clearly. When the heat sink component 2 is mated with the light pod 3, the mounting ring 3a is twisted, tightening the light pod 3 around the heat sink component 2. Therefore, the light pod 3 can be interchanged without removing the remainder of the fixture LF2 from the ceiling and without the need for tools or connecting loose wires.

[0076] FIG. 17 shows an exploded view of an exemplary fixture LF2 of the invention showing the mating of the heat sink 2 to the light pod 3. The heat sink 2 includes a mechanical pad 2a with a threaded circumference, allowing the mechanical pad 2a to make a thermal, electrical, and secure mechanical connection to another mechanical pad 3e (FIG. 21) on the light pod 3. The heat sink also includes a mating electrical connector 2b, permitting a connection with mating electrical connector 3f (FIG. 21) on the light pod 3. In certain examples, mating electrical connector 2b is a female connector and mating electrical connector 3f is a male connector. In other examples, mating electrical connector 2b is a male connector and mating electrical connector 3f is a female connector. Once mating electrical connector 2b is mated with connector 3f and mechanical pad 2a makes connect with mechanical pad 3e, the mounting ring 3 a is tightened around the threader circumference of mechanical pad 2a on the heat sink 2, locking the light pod 3 in place and mating the light pod 3 with the heat sink 2.

[0077] FIG. 18 shows a perspective view of an exemplary light pod 3 . In this example, the emission side of the light pod 3 is shown, where the media emission surface 3 c is coupled to mechanical holder 3b within the light pod 3. In certain examples, the media emission surface 3 c is an optical lens or light source. In other examples, the media emission surface 3 c includes TIR (total internal reflection) optics, a hexagonal cellular louver, an optical film, zoom sublens, collimator film laminated to a lens, color filter, diffused lens, clear lens, beam spreader lens, occupancy sensor lens, Li-Fi lens, or other similar media emission materials. The light pod cap 3g surrounds the media emission surface 3 c. In certain examples, the light pod cap 3g includes a beveled formation. In additional examples, the light pod cap 3g is adjusted to allow for narrow, medium, or wide beam spreads depending on the user’s preference. In certain examples having an adjustable light pod cap 3g, the light pod cap 3g includes markings to allow the user to identify how narrow or wide the beam of light emitted from the media emission surface 3 c will be.

[0078] Examples using the light pod 3 permit the user to change the light source without removing the fixture from the ceiling. After the light pod 3 is no longer functional, the light pod 3 can be interchanged by loosening the mounting ring 3a, removing the light pod 3 from the heat sink 2 (FIG. 17), providing a new second light pod, and releasably securing the second light pod to the heat sink 2. This system allows for replacement of the light pod 3 without removal or replacement of the entire fixture and without the use of tools. The modular light pod 3 also reduces waste by only requiring replacement of one component, rather than the whole fixture.

[0079] FIG. 19 shows a side view of an exemplary light pod 3. The light pod shows the mounting ring 3a coupled to the mechanical holder 3b, which in turn is coupled to the light pod cap 3g.

[0080] FIG. 20 shows a perspective overhead view of an exemplary light pod 3 with the transfer board 9 inserted into control input 7a. The light pod 3 includes the mounting ring 3a which tightens the light pod 3 to the heat sink 2 (FIG. 17). As previously shown in other examples, the mounting ring 3a is coupled to a mechanical holder 3b, which in turn is coupled to the light pod cap 3g. In certain examples, the light pod cap 3g is adjustable to adjust the width or narrowness of the light beam emitted from the media emission surface 3 c (FIG. 18). Additionally, on the end of the light pod 3 opposite the media emission surface 3 c, mechanical pad 3e is shown. The mechanical pad 3e of the light pod 3 makes contact with the mechanical pad 2a (FIG. 17), permitting a thermal electrical connection to travel between the light pod 3 and heat sink 2 (FIG. 17) without the use of loose wires or the need to attach the light pod 3 with tools. The transfer board 9 of the heat sink 2 (FIG. 17) mates with the control input 7a of the light pod 3.

[0081] FIG. 21 shows a perspective overhead view of another exemplary light pod 3. The exemplary light pod 3 is shown from the surface that mates with the heat sink 2 (FIG. 17). Mechanical pad 3e includes the underside of an LED secondary circuit board 126 (FIG. 4a) which makes direct connect with the mechanical pad 2a (FIG. 17) of the heat sink 2 (FIG. 17) for thermal connection from the light pod 3 to the heat sink 2. In certain examples, the secondary circuit board 126 is selected from the group including a chip-on-board (COB), a ceramic discharge metal halide (CDM), LEDs, or other similar sources. The exemplary light pod 3 also includes aligning components 3d, for example, positive keys, which helps align the light pod 3 with the mechanical pad 2a (FIG. 17) of the heat sink 2 (FIG. 17). In examples wherein the light pod 3 includes positive key aligning components 3d, the mechanical pad 2a (FIG. 17) includes recessed negative keys, wherein the positive key aligning components 3d mate with the negative keys. However, in other examples, the light pod 3 includes negative keys and the mechanical pad 2a (FIG. 17) includes positive keys. Mating electrical connector 3f is also shown, wherein the mating electrical connector of the heat sink 2b (FIG. 17) locks into the mating electrical connector 3f of the light pod 3f, and the mounting ring 3a is tightened to hold the light pod 3 in place mated with the heat sink 2 (FIG. 17).

[0082] FIG. 22 shows an exploded view of a light pod 3 of the invention and a view of the mechanical pad 2a of the heat sink 2 (FIG. 17). The example shows the mechanical pad 2a of the heat sink 2 (FIG. 17), as well as the mating electrical connector 2b. Mechanical pad 2a and electrical connector 2b, shown here in exploded view only for exemplary purposes, are permanently mounted to the heat sink 2 (FIG. 17). In certain examples, the secondary circuit board 3h is soldered or mounted to a holder 11 (FIGS. 23A and 23B) or, alternatively, mechanical pad 3e is used, wherein the mechanical pad 3 e includes the secondary circuit board 126 (FIG. 4a) as a single piece. In certain examples, the secondary circuit board 3h is a chip- on-board (COB) having a holder 11 (FIGS. 23 A and 23B) including a cut-out to permit a light source, such as a plurality of LEDS, to shine through the media emission surface 3c. In other examples, such as those where the secondary circuit board 3h is another source such as a tightly spaced array of LED chips. In this example, aligning component 3d is coupled to the mechanical pad 3e to secure the mechanical pad 3e and included circuit board 126 (FIG. 4a) in place. In this example, aligning component 3d is lengthened and includes a threaded area, adding greater security of the light pod 3 to the hat sink 2 (FIG. 17) when different types of media are used. Aligning component 3d directly couples to mechanical holder 3b. Mechanical holder 3b surrounds the media emission surface 3c and allows part of the media emission surface 3c to extend outside of the mechanical holder 3b to direct light out of the fixture. As mechanical holder 3b is coupled to aligning component 3d, a mounting ring 3a mates with the threads on the mechanical holder 3b and/or aligning component 3d. Approximately half of the threads on the mounting ring 3a, e.g., a proximal half, mate with threads on the mechanical holder 3b and/or aligning component 3d. The other half of threads on the mounting ring 3a, e.g., a distal half, will interlock with the mechanical pad 2a on the heat sink 2 (FIG. 17). When the mounting ring 3a is tightened, the light pod 3 is secured to the heat sink 2 (FIG. 17). In certain examples, a light pod cap 3g surrounds the media emission surface 3c and is coupled to the mechanical holder 3b. In certain examples, the light pod cap 3g is stationary and aids in directing the light beam of the fixture, whereas in other examples, the light pod cap 3g is adjustable and can alter its angle to create wider or narrower beams of light existing the fixture. In other examples using optical assemblies 112 (FIG. 1) such as louvers, zoom lenses, or frosted lenses already including a media emission surface 3c, components 3b and 3 c are not necessary to mount the optical assembly (shown by way of example as optical assembly 112 in FIG. 1) in the light fixture LF2.

[0083] FIG. 23A shows a perspective view of the front of a partial exemplary light pod 3 (FIG. 22) of the invention. In this example, the aligning component 3d of the light pod 3 (FIG. 22) is shown. In certain examples, a secondary circuit board 3h is mounted to aligning component 3d. In still further examples, secondary circuit board 3h is mounted on a holder 11. In examples where the secondary circuit board 3h is a chip-on-board (COB), the holder 11 includes contacts which align with contacts on the COB, powering the COB. In other examples, the secondary circuit board 3h includes a tightly spaced array of LED chips. As an alternative to using a secondary circuit board 3h, a second mechanical pad 3e is used, already integrating a secondary circuit board (126 in FIG. 3 or 3h) into the mechanical pad 3e as a single component. The second mechanical pad 3e is then mounted to alignment component 3d. It is to be understood that while certain examples of secondary circuit board 3h, such as a COB, require a holder, other types of secondary circuit boards do not require a holder.

[0084] FIG. 23B shows a perspective view of the back of a partial exemplary light pod 3 (FIG. 22) of the invention. The aligning component 3d of the light pod 3 (FIG. 22) is shown. As previously discussed, in certain examples, secondary circuit board 3h is used, or, alternatively, second mechanical pad 3e is used. In this particular example, the secondary circuit board 3h is a chip-on-board (COB), and the holder 11 is used. The secondary circuit board 3h is mounted to a holder 11, which is in turn mounted to the aligning component 3d. As an alternative, the single piece second mechanical pad 3e is mounted to the aligning component 3d without the need for a secondary circuit board 3h or holder 11.

[0085] It is also within the broadest scope of the invention that if a non -heat generating light source is used, the heat sink would be replaced with a holder or mounting component to hold the light pod. Moreover, it should be noted that the mother/daughter assembly is currently positioned adjacent to the heat sink, but if a light source that does not generate heat is used in close proximity to the power or signal mother/daughter assembly, or if heat is otherwise diverted from the mother/daughter assembly, then the mother/daughter assembly board can be mounted directly next to the transfer board, or the mother/daughter assembly board can include the transfer board, where this assembly or some portion of this assembly can be located directly in the housing or mounting supporting the light pod.

[0086] While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
