Abstract
Illumination devices are disclose having at least three thermally conductive fins that are attached to each other adjacent a central location and extend outward from the central location, with each of the fins having an opposed pair of major surfaces. The devices include a plurality of light-emitting diodes that emit light and produce heat, with at least one of the light-emitting diodes being mounted on each of the fins. The heat from the light-emitting diode flows along the fin and is radiated from at least one of the major surfaces, while the light from the light-emitting diode is reflected from the major surfaces of adjacent fins and exits the device.
Claims21
An illumination device comprising:
- at least three thermally conductive fins that are attached to each other adjacent a central location and extend outward from the central location, each of the fins having an opposed pair of major surfaces;
- and
- a plurality of light-emitting diodes that emit light and produce heat, with at least one of the light-emitting diodes being mounted on each of the fins, wherein the heat flows from the light-emitting diode along the fin and is radiated from at least one of the major surfaces, while the light from the light-emitting diode is reflected from the major surface and exits the device.
An illumination device comprising:
- at least three thermally conductive fins that are attached to each other adjacent a central location and extend outward from the central location, each of the fins having an opposed pair of major surfaces, each of the major surfaces facing a major surface of an adjacent fin;
- and
- a plurality of light-emitting diodes that emit light and produce heat, with at least one of the light-emitting diodes being mounted on each of the major surfaces of each of the fins, wherein the heat flows from the light-emitting diode along the fin and is radiated from the major surface, while the light from the light-emitting diode is reflected from the major surface of an adjacent fin to be directed away from the central location.
An illumination device comprising:
- at least three thermally conductive fins that are attached to each other adjacent a central location and extend outward from the central location, each of the fins having an opposed pair of major surfaces and an edge that is disposed distal to the central location;
- and
- a plurality of light-emitting diodes that emit light and produce heat, with at least one of the light-emitting diodes being mounted on each of the fins, wherein the heat flows from the light-emitting diode along the fin and is radiated from at least one of the major surfaces, while the light from the light-emitting diode is reflected from the major surface and exits the device.
