Abstract
A system for providing thermal protection for an LED light module and methods for manufacturing the same are described herein. The thermally protected LED light module may include a heat sink assembly thermally coupled to an LED light source, and a thermal protector. The thermal protector may be connected to the heat sink assembly by a mechanical fastener. Further, the thermal protector is electrically coupled to the LED light source and a power source where the thermal protector breaks the power provided to the LED light source from the power source when the thermal protector detects heat at or above a threshold temperature.
Claims20
A light fixture comprising:
- a heat sink assembly comprising at least one internal surface facing an interior of the light fixture and at least on external surface facing away from the light fixture;
- a light emitting diode (LED) light source in thermal communication with the at least one internal surface of the heat sink assembly;
- and
- a thermal protector switch mounted directly on the at least one internal surface of the heat sink assembly, wherein the thermal protector switch is electrically coupled to the LED light source and a power source, and wherein the thermal protector switch comprises a switch that opens and breaks the power provided to the LED light source from the power source when the thermal protector switch detects a temperature of the heat sink that is at or above a threshold temperature associated with the thermal protector switch.
A method comprising:
- providing a heat sink assembly in thermal communication with a light emitting diode (LED) light source and a thermal protector circuitry mounted directly on the heat sink assembly, wherein the thermal protector circuitry is electrically coupled to the LED light source and a power source and comprises a switch;
- powering the LED light source with the power source;
- detecting a first temperature value above a threshold value set by the thermal protector circuitry;
- and
- upon detecting the first temperature value above the threshold value, opening the switch to break the connection between the power source and the LED light source via the thermal protector circuitry.
A light fixture comprising:
- a heat sink assembly in thermal communication with a light emitting diode (LED) light source;
- and
- a thermal protector switch mounted directly on the heat sink assembly, wherein the thermal protector switch is electrically coupled to the LED light source and a power source, and wherein the thermal protector switch opens and breaks the power provided to the LED light source from the power source when the thermal protector switch detects a temperature of the heat sink assembly that is at or above a threshold temperature associated with the thermal protector switch.
