Abstract

A door assembly for a light fixture that includes a door frame formed of two opposing frame sides connected to two opposing frame ends that collectively form an opening and define a door frame plane. A reflector is positioned within the door frame to span the opening and to extend downwardly through the door frame plane such that at least a portion of the reflector extends below the door frame plane.

First claim

We claim:

1. A door assembly for a light fixture comprising:
a. a door frame comprising two frame sides connected to two frame ends, the frame sides opposing each other and the frame ends opposing each other, the door frame forming an opening and defining a door frame plane; and
b. a reflector positioned within the door frame to span the opening, wherein the reflector comprises opposing edges and an apex located between the edges, and wherein the apex extends downwardly through the door frame plane such that at least a portion of the reflector extends below the door frame plane.

2. The door assembly of claim 1 , wherein each of the two frame sides comprises a bottom edge, that lies in the door frame plane.

3. The door assembly of claim 2 , wherein each of the two frame ends comprises a bottom edge that lies in the door frame plane.

4. The door assembly of claim 1 , wherein at least one of the two frame sides comprises a mounting surface, wherein the door assembly further comprises at least one light emitting diode mounted on the mounting surface so as to direct emitted light toward the reflector.

5. The door assembly of claim 4 , wherein the at least one of the two frame sides comprises an angled side edge extending from a bottom edge, wherein the angled side edge shields the at least one light emitting diode from view when the door assembly is installed.

6. The door assembly of claim 5 , wherein the at least one of the two frame sides further comprises a mounting ledge extending from the angled side edge, wherein a kicker for directing light emitted from the at least one light emitting diode toward the reflector is positioned on the mounting ledge.

7. The door assembly of claim 1 , wherein at least one of the two frame sides comprises a slot and wherein the reflector comprises an edge that engages the slot.

8. The door assembly of claim 1 , wherein the two frame sides each comprise a slot and wherein the reflector comprises two opposing edges, wherein each of the two opposing edges engages the slot of one of the two frame sides to retain the reflector within the door frame.

9. The door assembly of claim 1 , wherein the reflector comprises two curved portions that intersect at an apex.

10. The door assembly of claim 9 , wherein the apex of the reflector is below the door frame plane.

11. The door assembly of claim 1 , wherein the reflector comprises a reflector substrate and a semi-specular optical material positioned on the reflector substrate.

12. A door assembly for a light fixture comprising:
a. a door frame comprising two opposing frame sides connected to two opposing frame ends, the door frame forming an opening and defining a door frame plane, wherein each of the two opposing frame sides comprises:
a bottom edge that lies in the door frame plane;
a mounting surface onto which plurality of light emitting diodes are mounted; and
a slot; and

b. a reflector positioned within the door frame to span the opening, wherein the reflector comprises two opposing edges, each of which engages the slot of one of the two opposing frame sides to retain the reflector within the door frame such that the reflector extends downwardly through the door frame plane such that at least a portion of the reflector extends below the door frame plane.

13. The door assembly of claim 12 , wherein each of the two opposing frame sides further comprises an angled side edge extending from the bottom edge, wherein the side edge shields the plurality of light emitting diodes from view when the door assembly is installed.

14. The door assembly of claim 13 , wherein each of the two opposing frame sides further comprises a mounting ledge extending from the angled side edge, wherein a kicker for directing light emitted from the plurality of light emitting diodes toward the reflector is positioned on the mounting ledge.

15. The door assembly of claim 12 , wherein the reflector comprises two curved portions that intersect at an apex.

16. The door assembly of claim 15 , wherein the apex of the reflector is below the door frame plane.
