Abstract

A lighting assembly for an existing linear fluorescent fixture includes a support, at least two opposing light emitting diodes (LED) on respective sides of the support configured to direct light in opposite general directions, a housing configured to cover the support and the at least two opposing LEDs; and end caps including electrical connectors to connect to electrical connections of the existing linear fluorescent fixture.

Claims

1. A lighting assembly for a linear fixture comprising:

a structural reinforcement configure to receive at least two printed circuit boards;

said two printed circuit boards oriented at least substantially parallel to each other and retained by said structural reinforcement;

at least two light emitting diodes (LED) on opposing sides of the two printed circuit boards and configured to direct light in oppositely general directions;

a housing comprised of an overmolded material selected from plastic, foam and mixtures thereof, and configured to cover the structural reinforcement and said printed circuit boards, said housing forming an outermost surface of said fixture, said housing including at least two chamfer and lens arrangements, each arrangement aligned with a corresponding LED; and

electrical connectors to connect to electrical connections of the linear fixture.

2. The assembly according to claim 1, wherein the housing is non-transparent.

3. The assembly according to claim 1, wherein the housing includes a recess formed along a length of the housing, said chamfer and lens arrangements disposed within said recess.

4. The lighting assembly of claim 3 wherein said recess defines a planar surface.

5. The assembly according to claim 1,

wherein the structural reinforcement includes at least one of a plurality of cooling ribs and a heat transfer channel.

6. The assembly according to claim 1, wherein the fixture includes electronics configured to convert AC current into DC current.

7. The lighting assembly of claim 1, wherein said housing includes at least one cylindrical portion.

8. The lighting assembly of claim 7, wherein said housing includes a cylindrical portion disposed at each end.

14. The lighting assembly of claim 1, wherein the electrical connectors include at least one of bi-pin connectors, recessed bi-pin connectors, and R17D connectors.

9. A lighting assembly comprising:

a structural reinforcement configured to facilitate proper orientation of a plurality of supports in relation to a housing, the structural reinforcement defining an opening between the at least two supports facing in opposite general directions;

at least one light emitting diode (LED) on a outward side of each of the plurality of supports, at least two of the LEDs emitting light in opposite general directions;

a housing forming an outermost surface of said assembly and comprised of an overmolded material selected from plastic, foam and mixtures thereof, and configured to have at least end regions circular in cross-section, said housing further configured to cover the plurality of supports and the LEDs, and wherein the housing is non-transparent and includes a plurality of lens and chamfer arrangements, each lens and chamfer arrangement being aligned with a corresponding LED; and

electrical connectors to connect to an electrical fixture.

10. The assembly of claim 9, wherein the structural reinforcement defines at least one of a plurality of cooling ribs and a heat transfer channel.

11. The assembly according to claim 9, wherein the electrical connectors include at least one of bi-pin connectors, recessed bi-pin connectors and R17D connectors.

12. The assembly of claim 9, wherein said material is selected from nylon, ABS plastic, polystyrene, and polyurethane foam.

13. The lighting assembly of claim 9, wherein said first supports comprise a first side of a PCB and an opposed second side of said PCB.

15. The lighting assembly of claim 9, wherein said housing includes at least one cylindrical portion.

16. The lighting apparatus of claim 15, wherein said housing includes a cylindrical portion disposed at each end.
