Abstract

A retrofit system for a luminaire including a tombstone socket is provided. The retrofit system includes an integrated holder and a tombstone socket receptacle. The integrated holder is configured to hold a solid state light engine and a power supply to power the solid state light engine. The tombstone socket receptacle is configured to interface with the tombstone socket of the luminaire, aligning the light engine in substantially the same place as a fluorescent lamp being replaced by the retrofit system within the luminaire.

Claims

1. A retrofit system for a luminaire including a tombstone socket, comprising:

an integrated holder, wherein the integrated holder is configured to hold a solid state light engine and a power supply to power the solid state light engine; and

a tombstone socket receptacle configured to interface with the tombstone socket of the luminaire.

2. The retrofit system of claim 1, wherein the integrated holder comprises opposing first and second longitudinal distal ends, the tombstone socket receptacle is located at the first longitudinal distal end of the integrated holder.

3. The retrofit system of claim 2, wherein the tombstone socket receptacle comprises two protrusions located at the first longitudinal distal end of the integrated holder, wherein the two protrusions are shaped so as to accommodate the tombstone socket of the luminaire.

4. The retrofit system of claim 2, wherein the tombstone socket receptacle comprises a plurality of tombstone socket receptacles.

5. The retrofit system of claim 4, wherein at least two tombstone socket receptacles of the plurality of tombstone socket receptacles are located at the first longitudinal distal end of the integrated holder.

6. The retrofit system of claim 4, wherein a tombstone socket receptacle of the plurality of tombstone socket receptacles is located at the second longitudinal distal end of the integrated holder.

7. The retrofit system of claim 6, wherein at least two tombstone socket receptacles of the plurality of tombstone socket receptacles are located at the second longitudinal distal end of the integrated holder.

8. The retrofit system of claim 1, wherein the integrated holder comprises an elongated structure.

9. The retrofit system of claim 8, wherein the integrated holder comprises opposing first and second longitudinal distal ends, wherein the opposing first and second longitudinal distal ends are on opposing ends of the elongated structure, and wherein the tombstone socket receptacle is located at the first longitudinal distal end.

10. The retrofit system of claim 8, wherein the retrofit system further comprises a light engine comprising an elongated shape and a plurality of solid state light sources arranged thereon, wherein the light engine is fastened to the elongated structure of the integrated holder such that the elongated shape of the light engine corresponds to the elongated structure of the integrated holder.

11. The retrofit system of claim 8, wherein the elongated structure comprises a three-dimensional profile extending along a longitudinal length of the elongated structure, wherein the three-dimensional profile defines a cavity in the elongated structure, and wherein the cavity holds a power supply.

12. The retrofit system of claim 8, wherein the integrated holder comprises opposing first and second longitudinal distal ends;

and

wherein the elongated structure comprises;

a three-dimensional profile extending along a longitudinal length of the elongated structure;

two laterally spaced sides walls, each comprising a longitudinal distal end portion adjacent at least one of the first longitudinal distal end and the second longitudinal distal end of the elongated structure and defining a notch in the side wall; and

a front wall disposed between the two laterally spaced side walls.

13. The retrofit system of claim 12, wherein each side wall has a height, and wherein each notch is defined by a decrease is a height of the side wall relative to an adjacent medial portion of each side wall.

14. The retrofit system of claim 12, wherein the three-dimensional profile comprises a U-shaped profile.

15. The retrofit system of claim 12, wherein a longitudinal distal end portion of at least one side wall adjacent at least one of the first longitudinal distal end and the second longitudinal distal end of the elongated structure defines a hook.

16. The retrofit system of claim 15, wherein the hook is configured to hook the retrofit system to the luminaire and to suspend the retrofit system in a vertically hanging position from the luminaire during installation of the retrofit system to the luminaire.

17. The retrofit system of claim 15, wherein the hook is in the form of a J-hook.

18. The retrofit system of claim 2, further comprising a plurality of light engines, each comprising an elongated shape and a plurality of solid state light sources arranged thereon;

and

wherein the integrated holder comprises a plurality of elongated structures and each one of the plurality of solid state light engines is arranged on a different one of the plurality of elongated structures.

19. The retrofit system of claim 18, wherein the plurality of elongated structures are spaced side-by-side by an elongated gap that separates the plurality of elongated structures from each other.
