Abstract

A luminaire includes a light source having a plurality of light emitting diodes (LEDs), a heat spreader, and a substantially ring-shaped trim plate. The heat spreader is disposed between and in thermal communication with the light source and the trim plate such that the heat spreader facilitates transfer of heat from the LEDs to the trim plate. The trim plate is structurally configured and disposed for dissipating heat generated by the light source. The trim plate has an outer dimension that is larger than: an opening defined by a nominally sized can light fixture; and, an opening defined by a nominally sized electrical junction box.

Claims (42)

1. A luminaire, comprising:

a light source comprising a plurality of light emitting diodes (LEDs);

a heat spreader;

a substantially ring-shaped trim plate;

the heat spreader being disposed between and in thermal communication with the light source and the trim plate such that the heat spreader facilitates transfer of heat from the LEDs to the trim plate;

the trim plate being structurally configured and disposed for dissipating heat generated by the light source; and

the trim plate having an outer dimension that is larger than: an opening defined by a nominally sized can light fixture; and, an opening defined by a nominally sized electrical junction box.

2. The luminaire of claim 1 , wherein:

the heat spreader and the trim plate are integrally formed as a single one-piece base such that a heat flow path between the heat spreader and the trim plate is continuous and uninterrupted.

3. The luminaire of claim 1 , further comprising:

a power conditioner structurally configured and disposed to receive AC voltage from an electrical supply and to provide DC voltage for the plurality of LEDs;

wherein the power conditioner is disposed, structurally configured and sized to fit at least partially within an interior space of the nominally sized can light fixture; and, the nominally sized electrical junction box.

4. The luminaire of claim 3 , wherein:

the power conditioner is disposed, structurally configured and sized to fit completely within an interior space of the nominally sized can light fixture.

5. The luminaire of claim 3 , wherein:

the power conditioner is disposed, structurally configured and sized to fit completely within an interior space of the nominally sized electrical junction box.

6. The luminaire of claim 3 , wherein:

the power conditioner comprises an electronic circuit board having electronic components configured to receive the AC voltage from the electrical supply line and to provide the DC voltage to the plurality of LEDs.

7. The luminaire of claim 1 , wherein:

the trim plate is structurally configured to be disposed completely external of the can light fixture and the electrical junction box.

8. The luminaire of claim 1 , further comprising:

an outer optic disposed in optical communication with the plurality of LEDs;

wherein the trim plate and the outer optic, in combination, are structurally configured and disposed to: cover an opening defined by the nominally sized can light fixture; and, cover an opening defined by the nominally sized electrical junction box.

9. The luminaire of claim 1 , wherein:

the trim plate is structurally configured and disposed to sit on an outer surface of a ceiling or a wall when the luminaire is installed in a user installation.

10. The luminaire of claim 1 , further comprising:

a power conditioner structurally configured and disposed to receive AC voltage from an electrical supply and to provide DC voltage to the plurality of LEDs;

wherein the power conditioner comprises an electronic circuit board having electronic components configured to receive the AC voltage from the electrical supply line and to provide the DC voltage to the plurality of LEDs.

11. A luminaire, comprising:

a light source comprising a plurality of light emitting diodes (LEDs);

a single one-piece base comprising both a heat spreader and a substantially ring-shaped trim plate such that a heat flow path between the heat spreader and the trim plate is continuous and uninterrupted, the heat spreader being disposed between and in thermal communication with the light source and the trim plate such that the heat spreader facilitates transfer of heat from the LEDs to the trim plate, the trim plate being structurally configured and disposed for dissipating heat generated by the light source;

a power conditioner structurally configured and disposed to receive AC voltage from an electrical supply and to provide DC voltage for the plurality of LEDs, the power conditioner being disposed, structurally configured and sized to fit at least partially within an interior space of: a nominally sized can light fixture; and, a nominally sized electrical junction box.

12. The luminaire of claim 11 , wherein:

the trim plate has an outer dimension that is larger than: an opening defined by the nominally sized can light fixture; and, an opening defined by the nominally sized electrical junction box.

13. The luminaire of claim 11 , wherein:

the trim plate is structurally configured to be disposed completely external of the can light fixture and the electrical junction box.

14. The luminaire of claim 11 , further comprising:

an outer optic disposed in optical communication with the plurality of LEDs.

15. The luminaire of claim 11 , wherein:

the power conditioner is disposed, structurally configured and sized to fit completely within an interior space of the nominally sized can light fixture.

16. The luminaire of claim 11 , wherein:

the power conditioner is disposed, structurally configured and sized to fit completely within an interior space of the nominally sized electrical junction box.
