Abstract
A light fixture includes a lighting module and a heat sink. The lighting module includes a plurality of light emitting diodes and a heat sink. The light emitting diodes are configured to project light onto an area beneath the light fixture. The heat sink overlies the lighting module and is configured to dissipate heat away from the lighting module. The heat sink includes a base plate, a first base fin and a second base fin. The first base fin extends upwardly from the base plate. The second base fin extends upwardly from the base plate and is spaced from the first base fin.
Claims19
A light fixture comprising:
- a lighting module comprising a plurality of light emitting diodes that are configured to project light onto an area beneath the light fixture;
- and
- a heat sink overlying the lighting module and configured to dissipate heat away from the lighting module, the heat sink comprising:
- a base plate;
- a first base fin extending upwardly from the base plate;
- a second base fin extending upwardly from the base plate and spaced from the first base fin;
- a first supplemental fin extending laterally from the first base fin towards the second base fin;
- and
- a second supplemental fin extending laterally from the second base fin towards the first base fin and spaced from the first supplemental fin, wherein each of the first supplemental fin and the second supplemental fin extend upwardly from the base plate.
A light fixture comprising:
- a lighting module comprising a plurality of light emitting diodes that are configured to project light onto an area beneath the light fixture;
- a heat sink overlying the lighting module and configured to dissipate heat away from the lighting module, the heat sink comprising:
- a base plate;
- and
- a plurality of base fins extending upwardly from the base plate, each base fin of the plurality of base fins being interposed between and spaced from each other;
- and
- a driver housing overlying the heat sink and configured to house a driver, the driver housing comprising:
- a lid;
- a base;
- and
- a plurality of lower fins configured to dissipate heat away from the driver, the plurality of lower fins extending downwardly from the base and towards the base plate, wherein each lower fin of the plurality of lower fins is interposed between and spaced from a pair of base fins of the plurality of base fins such that the plurality of the lower fins and the plurality of base fins are intersected by an imaginary plane.
A light fixture comprising:
- a lighting module comprising a plurality of light emitting diodes that are configured to project light onto an area beneath the light fixture;
- and
- a heat sink overlying the lighting module and configured to dissipate heat away from the lighting module, the heat sink comprising:
- a base plate;
- a first base fin extending upwardly from the base plate;
- a second base fin extending upwardly from the base plate and spaced from the first base fin;
- a first supplemental fin extending from the first base fin towards the second base fin;
- and
- a second supplemental fin extending from the second base fin towards the first base fin and spaced from the first supplemental fin;
- a driver housing overlying the heat sink and comprising:
- a lid;
- a base;
- and
- a lower fin extending downwardly from the base and towards the base plate, wherein the lower fin is interposed between and spaced from the first base fin and the second base fin such that the lower fin, the first base fin and the second base fin are intersected by an imaginary plane.
