Abstract

A light assembly contains a troffer containing a housing. One or more LED light units are contained within the troffer, wherein each of the LED light units contain only one corresponding conductive end cap. A pair of conductors extending from each of the corresponding conductive end caps are mated with a corresponding socket contained within a DC power supply module contained within the troffer.

Claims

1. A light assembly comprising:

a troffer containing a housing;

one or more LED light units contained within said troffer, each of said LED light units containing only one corresponding conductive end cap;

a pair of conductors extending from each of said corresponding conductive end caps; and

a first DC power supply module separable from said one or more LED light units and contained within said troffer, said first DC power supply module containing one or more female sockets for seating of a corresponding pair of conductors from one of said one or more LED light units.

2. The light assembly of claim 1 wherein said troffer contains a first end and a second end, and said DC power supply module is housed at said first end, and said one or more LED light units extend from said first end to said second end.

3. The light assembly of claim 1 wherein said light assembly further comprising:

a support rack fixed within said second end of said troffer; and

one or more support elements corresponding in number to said one or more LED light units,

wherein each of said one or more LED light units extend from said DC power supply module to a corresponding one of said one or more support elements, each of said one or more LED light units removably fixed within a corresponding one of said one or more support elements.

4. The light assembly of claim 2 further comprising:

a sub-housing contained within said housing at said first end, wherein said DC power supply module is removably fixed within said sub-housing.

5. The light assembly of claim 1 further comprising a motion sensor, a light sensor, or a programmable algorithm in electronic communication with said DC power supply module for selectively lighting said one or more LED units upon a predetermined event.

6. The light assembly of claim 1 wherein said one or more LED lighting units are one or more DC-powered LED tubes or LED strips.

7. The light assembly of claim 1 further comprising a second DC power supply module in electronic communication with said first DC power supply module, wherein said second DC power supply module contained within said troffer contains one or more female sockets for seating of a corresponding pair of conductors from one of said one or more LED light units.

8. A light assembly comprising:

a troffer containing a housing;

a plurality of LED light units contained within said troffer, each of said LED light units containing only one corresponding conductive end cap;

a pair of conductors extending from each of said corresponding conductive end caps;

a DC power supply module separable from said plurality of LED light units and contained within said troffer, said power supply module containing a plurality of female sockets for seating of a corresponding pair of conductors from one of said plurality of LED light units; and

a plurality of drivers electronically communicating with said DC power supply module, each of said plurality of drivers electronically communicating with a corresponding one of said plurality of LED light units,

wherein each of said plurality of drivers are operatively independent of one another.

9. The light assembly of claim 8 wherein said plurality of drivers are a plurality of AC/DC converters or a plurality of rectifiers.

10. The light assembly of claim 8 structured as a modular assembly, wherein each of said plurality of LED light units, each of said plurality of drivers, and said DC power supply module are independently removable from said light assembly for replacement or maintenance thereof.
