DETAILED DESCRIPTION

[0023] Embodiments of the present invention generally relate to a landscape light. Specifically, certain exemplary embodiments of the present invention provide various new and novel features for a landscape light, such as a landscape light having laser light sources. Landscape lights according to embodiments of the present invention can, for example, be used as interior or exterior festive and/or decorative lighting in connection with holidays such as Christmas, Halloween, etc. Additionally, the landscape lights according to embodiments of the present invention may be used in place of other traditional decorative lighting, such as string lights, etc. Although the embodiments of the present invention are primarily described with respect to a landscape light, it is not limited thereto, and it should be noted that the exemplary apparatus and systems described herein may be used in connection with any lighting apparatus

[0024] FIG. 1 is an illustration of an exemplary landscape light 10 according to an embodiment of the present invention. As shown in FIG. 1 , landscape light 10 can include light sources 14 and 16 and lenses 14a and 16a housed within light projector housing 12. Although landscape light 10 is shown in FIG. 1 having only two light source 14 and 16, landscape light 10 can include any number and type of light sources. For example, landscape light 10 can include one, two, three, or more light sources. Further, each of the light sources can be any type of light source that can produce the type of light desired, such as, for example, light sources 14 and 16 may include lasers, incandescent bulbs, and/or light emitting diodes (LEDs). Optionally, light sources 14 and 16 can produce lights having the same color. Alternatively, light sources 14 and 16 can produce lights having different colors (e.g., red, green, white, blue, etc.). Further, as shown in FIG. 1 , landscape light 10 can include lenses 14a and 16a, which can correspond to light sources 14 and 16, respectively. Lenses 14a and 16a can include any type of optical element that can manipulate and/or condition the light produced by light sources 14 and 16 in a desired manner. For example, lenses 14a and 16a can include diffractive features (e.g., diffractive holographic optics) configured to disperse the light generated by light sources 14 and 16 into a plurality of discrete points of light when projected onto a surface. Lenses 14a and 16a can also scatter the light generated by light sources 14 and 16 so as to lower the power of the light, thereby reducing the potential risk associated with exposure to the light in embodiments where light sources 14 and 16 may include lasers.

[0025] According to certain embodiments of the present invention, in operation, landscape light 10 can project light produced by light sources 14 and 16 onto a target surface. For example, light produced by light sources 14 and 16 may be manipulated or conditioned by lenses 14a and 16a and be projected onto a target surface, such as a wall or other structure. In an embodiment where lenses 14a and 16a include diffractive elements configured to disperse the light generated by light sources 14 and 16, landscape light may project a plurality of discrete points of light onto the target surface. Landscape light 10 may also include various modes of operation. For example, landscape light 10 may include mode where the lights produced by light sources 14 and 16 can be flashed, strobed, or pulsed at predetermined, or randomized intervals. This may be performed by modulating the power delivered to light sources 14 and 16 in accordance with the desired flashing, pulsing, or strobing pattern. Additionally, landscape light 10 may also a visual effect assembly, which can produce various visual effects using the lights produced by light sources 14 and 16. For example, visual effect assembly may be configured to produce a shimmering effect of the light, a movement of the light across the target surface, a "raining" effect of the light, etc. Visual effect assembly may also be configured to produce the flashing, pulsing, or strobing pattern of the light in addition to or in place of any power modulation techniques utilized to achieve these effects.

[0026] As shown in FIG. 1 , landscape light 10 can also include mounting bracket 20, ground stake 22, and power cord 18. Power cord 18 can be connected to a power supply or transformer (not illustrated). Optionally, landscape light 10 can include a wireless remote control 30, which can enable wireless control of landscape light 10. As shown in FIG. 1 , ground stake 22 and light projector housing 12 may be rotatably coupled to mounting bracket 20. This can allow user to aim and adjust the direction of the light produced by landscape light 10. For example, the angle of light projector housing 12 can be adjusted relative to mounting bracket 20, and mounting bracket 20 can be rotatably adjusted relative to ground stake 22. Thus, landscape light 10 can be adjusted in two degrees of freedom to provide nearly a full range of motion of adjustments. This can enable a user, for example, to adjust and aim the light produced by landscape light 10 to be projected on various targets even after it has been staked into the ground.

[0027] Additionally, landscape light 10 can include a wireless remote control 30 that can enable wireless operation of landscape light 10. For example, landscape light 10 can include a wireless transmitter/receiver, which can wirelessly communicate with a remote control 30 to enable wireless operation of landscape light 10. For example, the wireless transmitter/receiver can employ radio frequency ("RF"), Bluetooth, and/or WiFi technology to facilitate wireless communication between landscape light 10 and remote control 30. According to certain embodiments, landscape light 10 can be wirelessly operated via remote control 30. For example, remote control 30 can control powering landscape light 10 ON and/or OFF, changing the operation of light sources 14 and 16 (e.g., choosing between having one of light source 14 or 16 in an ON condition or having both light sources 14 and 16 in an ON condition), controlling a visual effect setting (e.g., flashing, movement, shimmering, strobing, etc.), controlling a timer setting, etc. Further remote control 30 can indicate and display the current operating status of landscape light 10 (e.g., whether or not landscape light 10 is ON or OFF and/or the mode of operation). According to certain embodiments, remote control 30 can be implemented via an app on a mobile device such as a smartphone or tablet, or via a web-based application on a computer.

Further, optical element 222 may be coupled to a motor, or other articulating element, that can cause optical element 222 to be articulated in a defined manner, which when combined with the optical feature of optical element 222, can create the desired visual effect. As noted herein, visual effect assembly 220 can create a flashing, pulsing, or strobing pattern, a shimmering effect, a movement of the light across the target surface, a "raining" effect, etc. As shown in FIGs. 2A and 2B, optical element 222 may include a disk having optical features disposed thereon, which can be rotated in front of light source in the direction of arrow A to create various optical effects as the light generated by light source 230 interacts with rotating optical element 222. Although visual effect assembly 220 is shown to include a rotating optical wheel, visual effect assembly 220 can include any structure or programming that can enable creating the desired visual effects of the light.

[0029] FIG. 3 shows an exemplary landscape light 310 according to an embodiment of the present invention. Similarly to landscape light 10 shown in FIG. 1 , landscape light 310 includes housing 312, light sources 314 and 316, and ground stake 322. Additionally, landscape light 310 includes spotlights 332 and an adjustment mechanism 340. Spotlights 332 may include any type of light source having sufficient power to illuminate a desired area. For example, spotlights 332 may include light-emitting diodes (LED), halogen bulbs, high-intensity discharge gas lamps, etc., which may illuminate an area in which the light generated by light sources 314 and 316 are projected. For example, spotlights 332 may illuminate a surface such as a wall, and a plurality of discrete points of light generated by light sources 314 and 316 may be projected on the wall within the area of illumination. In operation, spotlights 332 may be configured to be operable in a continuously on state, a flashing mode of operation, varying levels of brightness/intensity, etc. Operation of the spotlights 332 can be in addition to and can augment any visual effects that can be produced/created as described herein. Further, certain visual effects (e.g., flashing, movement, etc.) can be implemented on the light generated by light sources 314 and 316 as well as the light generated by spotlights 332.

[0030] Further, as shown in FIG. 3, landscape light 310 can include adjustment mechanism 340.

[0031 ] FIGS. 4A-4D show landscape lights 410 and 410a including pattern generation assemblies 450 and 450a, respectively, according to certain embodiments of the present invention. As shown in FIGs. 4A-4D, landscape lights 410 and 410a are similar to landscape light 10, but include pattern generation assemblies 450 and 450a. Pattern generation assemblies 450 and 450a can create patterns in the light produced by the light sources of landscape lights 410 and 410a, thereby enabling landscape lights 410 and 410a to be project light in specific patterns and shapes. For example, as shown in FIGs. 4A-4C, pattern generation assembly 450 may include pattern generators 452 mounted on a slide cartridge 454.
