Abstract
Provided are an illumination device and a light fixture including the illumination device. The illumination device includes a body formed of a thermally-conductive material that includes a planar heat transfer surface and a fastener that is compatible with a base that couples the body to the light fixture. A substrate formed, at least in part from a dielectric material supports an array of light emitting diodes and a plurality of contacts electrically connected to the light emitting diodes. A thermally-conductive planar surface is provided to the dielectric material of the substrate to be placed in thermal communication with the heat transfer surface and conduct heat generated by the light emitting diodes to the body.
Claims25
An illumination device comprising:
- a body formed of a thermally-conductive material, the body comprising a heat transfer surface and defining an internal bore;
- and
- a substrate formed of a dielectric material that supports at least one LED, wherein a thermally-conductive coating or layer is provided to the dielectric material, said thermally-conductive coating or layer being in thermal communication with the heat transfer surface to conduct heat generated by the at least one LED to the body.
An illumination device comprising:
- a body formed of a thermally-conductive material, the body comprising a heat transfer surface and defining an internal bore;
- and
- a substrate formed of a dielectric material that supports at least one LED and a plurality of contacts electrically connected to the at least one LED, wherein a thermally-conductive surface is provided to the dielectric material, said thermally-conductive surface being configured to conduct heat generated by the at least one LED to the body when placed in thermal communication with said heat transfer surface.
A light fixture comprising:
- a plurality of bases;
- and
- an illumination device coupled to each of the plurality of bases, each of the illumination devices comprising:
- a body formed of a thermally-conductive material, the body comprising a heat transfer surface and an internal bore that is cooperable with the associated base;
- and
- a substrate formed of a dielectric material that supports at least one LED and a plurality of contacts electrically connected to the at least one LED, wherein a thermally-conductive surface is provided to the dielectric material that is to be placed in thermal communication with the heat transfer surface to conduct heat generated by the at least one LED to the body.
An illumination device comprising:
- a body formed of a thermally-conductive material, the body comprising a heat transfer surface and being compatible with a base that is to couple the body to a light fixture;
- and
- a substrate formed of a dielectric material that supports at least one LED, wherein a thermally-conductive coating or layer is provided to the dielectric material, said thermally-conductive coating or layer being in thermal communication with the heat transfer surface via an interface that provides intimate thermal contact therebetween to conduct heat generated by the at least one LED to the body;
- said body being in thermal communication with said light fixture and effective to dissipate said heat generated by the at least one LED into said fixture.
