Abstract

Claims (79)

1. An apparatus comprising:

a lighting assembly that:

defines a central axis; and

is configured to be removeable through a first aperture defined by a panel; and

a heat sink that is configured to:

be mounted above the panel;

retain the lighting assembly; and

release the lighting assembly in response to a translation of the lighting assembly along the central axis without a rotation of the lighting assembly about the central axis;

wherein:

the first aperture has a first diameter; and

the heat sink has a second diameter that is larger than the first diameter.

2. The apparatus of claim 1 wherein the second diameter is at least 10 percent larger than the first diameter.

3. The apparatus of claim 1 wherein the second diameter is at least two times larger than the first diameter.

4. The apparatus of claim 1 wherein the second diameter is at least four times larger than the first diameter.

5. The apparatus of claim 1 wherein the panel is a ceiling.

6. The apparatus of claim 5 wherein the panel includes plaster.

7. The apparatus of claim 5 wherein the panel includes sheet rock.

8. The apparatus of claim 5 wherein the panel includes wood.

9. The apparatus of claim 1 wherein the lighting assembly is configured to be removed through the first aperture without causing damage to the panel.

10. The apparatus of claim 1 wherein the lighting assembly is magnetically retained by the heat sink.

11. The apparatus of claim 10 wherein the lighting assembly and the heat sink are configured so that the heat sink draws heat from the lighting assembly when the lighting assembly is magnetically retained by the heat sink.

12. The apparatus of claim 1 wherein the lighting assembly includes:

a light engine base;

an LED brace that is configured to:

be fastened to the light engine base; and

hold an LED light source;

a reflector; and

a spackle plate;

wherein the reflector is:

positioned to form a beam of light emitted by the LED light source; and

configured to engage the spackle plate.

13. The apparatus of claim 12 wherein;

the heat sink is configured to be mounted above a first side of the panel; and

the spackle plate is configured to:

be disposed flush against a second side of the panel; and

retain a surface treatment.

14. The apparatus of claim 12 wherein the lighting assembly is configured to be removable through a second aperture defined by the spackle plate without removal of the spackle plate.

15. The apparatus of claim 1 further including:

a power lead that is configured to provide power to the lighting assembly; and

a connector that is attached to an end of the power lead;

wherein the end is configured to be accessible, to a user, below the panel when the lighting assembly is released from the heat sink.

16. An apparatus for lighting comprising:

a lighting assembly that:

defines a central axis; and

is configured to be removeable through an aperture defined by a spackle plate; and

a heat sink that is configured to:

retain the lighting assembly; and

release the lighting assembly in response to a translation of the lighting assembly along the central axis without a rotation of the lighting assembly about the central axis;

wherein:

the aperture has a first diameter; and

the heat sink has a second diameter that is larger than the first diameter.

17. The apparatus of claim 16 wherein the second diameter is at least 10 percent larger than the first diameter.

18. The apparatus of claim 16 wherein the second diameter is at least two times larger than the first diameter.

19. The apparatus of claim 16 wherein the second diameter is at least four times larger than the first diameter.

20. The apparatus of claim 16 wherein:

the heat sink is configured to be mounted above a first side of a panel; and

the spackle plate is configured to:

be disposed flush against a second side of the panel; and

retain a surface treatment.

21. The apparatus of claim 20 wherein the panel is a ceiling.

22. The apparatus of claim 21 wherein the panel includes plaster.

23. The apparatus of claim 21 wherein the panel includes sheet rock.

24. The apparatus of claim 20 wherein the lighting assembly is configured to be removed through the aperture without causing damage to the panel or surface treatment.

25. The apparatus of claim 16 wherein the lighting assembly is magnetically retained by the heat sink.

26. The apparatus of claim 25 wherein the lighting assembly and the heat sink are configured so that the heat sink draws heat from the lighting assembly when the lighting assembly is magnetically retained by the heat sink.

27. The apparatus of claim 16 wherein the lighting assembly includes:

a light engine base;

an LED brace that is configured to:

be fastened to the light engine base; and

hold an LED light source; and

a reflector;

wherein the reflector is:

positioned to form a beam of light emitted by the LED light source; and

configured to engage the spackle plate.

28. The apparatus of claim 16 wherein the lighting assembly is configured to be removable through the aperture defined by the spackle plate without removal of the spackle plate.

29. The apparatus of claim 16 further including:

a power lead that is configured to provide power to the lighting assembly; and

a connector that is attached to an end of the power lead;

wherein the end is configured to be accessible, to a user, below the spackle plate when the lighting assembly is released from the heat sink.
