Abstract
A lighting device is disclosed herein. The lighting device may include an LED module having a plurality of LEDs and a heat sink that dissipates heat generated by the LEDs. The heat sink may be electrically insulated from the LEDs and other electrical components to improve the inner voltage property of the lighting device. In the lighting device as disclosed herein, a number of connectors required to assemble the various components of the lighting device may be reduced, and efficiency during assembly may be improved accordingly.
Claims20
A lighting apparatus comprising:
- a heat sink having a first surface positioned opposite a second surface;
- a light emitting diode module provided over the first surface, wherein the light emitting diode module is thermally coupled to the heat sink;
- a housing positioned on the second surface, wherein the housing is thermally insulated from the heat sink;
- and
- at least one fastener that attaches the light emitting diode module to the housing.

A lighting device comprising:
- a light emitting module having a plurality of LEDs mounted thereon;
- a heat sink configured to dissipate heat generated from the light emitting module;
- and
- a base that houses electrical components configured to provide power to the light emitting module, wherein
- the heat sink is positioned between the base and the light emitting module, and configured to be electrically insulated from the light emitting module and thermally insulated from the base.
2 more elements
A lighting device comprising:
- an LED module having a plurality of LEDs mounted thereon;
- a heat sink positioned below the LED module;
- a thermally insulated base positioned below the heat sink;
- and
- a connector configured to attach the LED module, the heat sink, and the base to each other, wherein the connector attaches the LED module to the base without touching the heat sink.
