Low profile light
DC CAFCFirst Claim
1. A luminaire, comprising:
- a heat spreader and a heat sink thermally coupled to the heat spreader, the heat sink being substantially ring-shaped and being disposed around and coupled to an outer periphery of the heat spreader;
an outer optic securely retained relative to at least one of the heat spreader and the heat sink; and
a light source disposed in thermal communication with the heat spreader, the light source comprising a plurality of light emitting diodes (LEDs) that are disposed on the heat spreader such that the heat spreader dissipates heat from the LEDs;
wherein the heat spreader, the heat sink and the outer optic, in combination, have an overall height H and an overall outside dimension D such that the ratio of H/D is equal to or less than 0.25;
wherein the combination defined by the heat spreader, the heat sink and the outer optic, is so dimensioned as to;
cover an opening defined by a nominally sized four-inch can light fixture; and
, cover an opening defined by a nominally sized four-inch electrical junction box.

Abstract
A luminaire includes a heat spreader and a heat sink thermally coupled to and disposed diametrically outboard of the heat spreader, an outer optic securely retained relative to at least one of the heat spreader and the heat sink, and a light source disposed in thermal communication with the heat spreader, the light source having a plurality of light emitting diodes (LEDs). The heat spreader, the heat sink and the outer optic, in combination, have an overall height H and an overall outside dimension D such that the ratio of H/D is equal to or less than 0.25. The combination defined by the heat spreader, the heat sink and the outer optic, is so dimensioned as to: cover an opening defined by a nominally sized four-inch can light fixture; and, cover an opening defined by a nominally sized four-inch electrical junction box.

20. A luminaire, comprising:
-
a heat spreader and a ring-shaped heat sink thermally coupled to and disposed diametrically outboard of the heat spreader; an outer optic securely retained relative to at least one of the heat spreader and the heat sink; a light source disposed in thermal communication with the heat spreader, the light source comprising a plurality of light emitting diodes (LEDs) that are disposed on the heat spreader such that the heat spreader dissipates heat from the LEDs; the heat spreader, the heat sink and the outer optic define a combination having an overall height H and an overall outside dimension D such that the ratio of H/D is equal to or less than 0.25; and a power conditioner disposed in electrical communication with the light source, the power conditioner being configured to receive AC voltage from an electrical supply line and to deliver DC voltage to the plurality of LEDs, the power conditioner being so dimensioned as to fit within at least one of;
a nominally sized four-inch can light fixture; and
, a nominally sized four-inch electrical junction box. - View Dependent Claims (21, 22, 23)
