TECHNICAL FIELD

[001] The present disclosure relates to the field of light emitting diode (LED) lighting, controls and installation technology. More particularly, the present disclosure relates to LED Tube lights with a system for plug-in type detachable constant current driver located in the end cap suitable for different types of fixing or installation and using end caps to customize LED tube lights for automatic control and operation, wireless connectivity and to provide battery backup power as and when required.

BACKGROUND

[002] Generally, fluorescent or incandescent lamps are widely used in artificial lighting. Among the two fluorescent lamp is much preferred in general purpose lighting as it offers higher efficiency, consumes less power, delivers higher lumens, generates low heat and has long life compared to incandescent lamps. It used in the form of tube lights, CFL in various size and shapes. The fluorescent tube lights are generally in sizes 1500mm, 1200mm, 600mm, 300mm and vary in diameter and classified as T12, T8, T5. They are installed in sheet metal fixtures or holders that are integrated with magnetic ballast with a starter or electronic ballast and with power supply on both ends through metal pins classified as G13 size. T8 and T12 tube lights are manufactured with metal end caps with G13 PINs suitable for G13 holder of the fixture. Even though lamps vary in length, size of the end caps or G13 pins is standard in T8/T12 diameter. Tube lights constitute 55% of general purpose lighting in the residential sector and 58% of commercial sector in India and they are the most used lamps worldwide.

[003] Lighting technology based on Light Emitting Diodes usually called as LED has rapidly gained popularity due to 50% higher efficiency, long life, more directional in light delivery than florescent lamps. LED lights are classified as luminaires that are designed in different shapes and sizes to fulfill the lighting requirements as per applications and as retrofit lamps designed in a form compatible to replace conventional lamps like bulbs and tube lights. LED bulbs are widely used to address power consumption in lighting as it is easy to replace conventional incandescent, halogen or CFL lamps in designed suitable for different sockets or holders.

[004] Complexities in retrofitting Tube lights: LED Tube lights are also being used to replace conventional florescent tube lights, but not as widely as bulbs, due to complexities involved in modifying the tube light fixtures to suit LED tube lights and skilled people are required to do the job.

[005] LED tube lights like all other LED lights requires a constant current supply device to supply power to LED components and are simply called drivers. Initially LED driver circuits or assembly were large in size and were placed externally like the choke of the conventional tube lights. Later the drivers were designed in small form factor suitable to integrate in to the extruded aluminum heat sink along with the LED PCB. LEDs as components have very long life compared to the electronic drivers due to low life of the capacitors used in the circuit. Drivers are prone to failures due to electrical fluctuations or other reasons and often require highly skilled technical persons to repair or replace failed drivers which are highly expensive too. This can only be accomplished either through onsite service or customers have to carry the tube light to the service or dealer point for rectification. Due to the high cost of service lamp failures are often addressed by replacing the lamp with new, during warranty period or the customer has to discard the LED tube light and buy new one after warranty.

[006] Driver failures wasting useful lamps: Drivers constitute only 20% of the value of total LED tube light and 80% of the useful lamps are discarded due to the complexities in replacing failed drivers. This constraint is also resulting in generation of avoidable electronic waste resulting in other environmental hazards.

[007] Further, LED tube lights are many times expensive than the conventional florescent tube lights and the uncertainties involved in the useful life of the LED tube lights, together with the complexities in retrofitting are keeping many users in wait in spite of huge benefits offered in terms of savings in energy and operational costs.

[008] Accelerated Lumen Depreciation: Another problem in the existing design of LED tube lights is the heat generated by the driver assembly that gets transmitted to the LED PCB as common heat sink is used by both. Heat accelerates the lumen depreciation of LEDs and reduces their life. Also most customers in existing buildings are choosing to retrofit the conventional fluorescent lamps with LED tube lights in the existing fixtures. But customers of new buildings prefer LED batten Tube lights that can be directly mounted without any need for a fixture, to simplify installation and improve on aesthetics.

[009] Lack of unified standard in design: Different LED retrofit tube light models are available in the market with varying designs and standards. Some LED Tube lights require one end power and some on both ends of the fixture. There are some models available that can be directly installed in fixtures with magnetic ballast and some compatible to electronic ballast and it is often difficult and confusing for the common consumer. Even in LED Lamps designed for direct replacement of existing fixtures, the ballast continues to exist in the circuit and will consume some power without any purpose.

[010] This requirement of rewiring of existing fixtures makes the process of retrofitting complicated, labor intensive and adds additional cost to project over and above the cost of LED retrofit tube lights. Further the process requires technically qualified persons and common people cannot execute the job like with LED Bulbs.

[011] Due to this reason most Demand Side Management (DSM) programs sponsored by governments offer LED bulbs to save energy. But, except for users of Below Poverty Line (BPL), others commonly use tube lights for task lighting, which leaves large and unaddressed power consumption in the lighting.

[012] Design drawbacks in Batten Models: Generally, Civil Engineers and Electricians provide power supply for the tube lights at the center of the tube light closer to the placement of choke of conventional tube lights. This creates a problem with LED batten tube lights having one side power with 2 feet wire being visible and creating shabby look.

[013] Currently available retrofit and batten models are made with semi-finished components of different specifications. This requires large investment in tooling and raw material stock and finished goods stock. Even dealers and distributors need to keep stock of many different models to fulfill the requirements of customers. Further customers are stuck with a LED tube light of particular specifications and cannot add or remove any feature like sensor based auto switching, dimming or any other feature and have buy a new tube light again with the required features suitable for the requirement.

[014] In the light of aforementioned discussion there exists a need for system that would ameliorate or overcome the above mentioned disadvantages.

The FR4grade printed circuit board (PCB) 420 and LED driver are separated, the LED driver is housed in detachable light emitting diode (LED) driver housing 402a and 402b to prevent the transfer of heat generated to the light-emitting diode surface-mount-device (LED SMD) 422. The driver end caps 404a and 404b can be used to open and close the detachable light emitting diode (LED) driver housing 402a and 402b in case of faults.

[067] As shown in FIG. 4C and FIG. 4D, the light emitting diode (LED) driver housing 402a and 402b and the shape of wall mounting 414 uses fixing screws 428(As shown in FIG. 4A)and a slot424 in the bottom side for wall mounting. The protruded knob 408 prevents reverse connection and the driver housing end caps 404a and 404b comprises a provision for the fixing screws 408a and 408b (As shown in FIG. 4B) to the driver 402a and 402b.

[068] As shown in FIG. 4C and FIG. 4D, the second design driver embodiment 400c and 400d secured to the driver end caps 404a, 404b and inner end caps 404c and 404d and fixed to the light emitting diode (LED) tube light with the G13 pins 406a and 406b for converting into to wall mounting 414 and hanging configuration (as shown in FIG. 4D). The cavity bracket 424 in the bottom side of the driver end caps 404a, 404b and driver housing 402a and 402b is used for wall mounting. The aluminum rod 426 penetrates through the cavity bracket 424 at the both ends of the light emitting diode (LED) driver housing 402a and 402b and locked with metal brackets (410) ensures and makes the LED tube light anti - theft.

[069] As shown in FIG. 4C and FIG. 4D, the aluminum heat sink 412a further comprises a conduit 430 at the back side of the tube light lamp. The power supply wire 434 through the power supply wire hole from the driver housing 402a is passed through inner end cap 404c to the conduit 430 in the aluminum heat sink 412a in a concealed manner from normal vision to improve aesthetics and protect the wire. Further the in-built system for concealed wiring used to supply input power 432at the center of the tube, makes the power connection simple and unique.
