Abstract:
1. A lighting system comprising: a light emitting diode (LED); a first container, containing a first phase change material, thermally coupled to the LED of the lighting system, wherein heat generated by the LED during operation is conducted to the first phase change material, and further wherein a first transition point temperature of the first phase change material is lower than a desired LED operating temperature to account for a temperature drop between the LED and the first phase change material; and a thermally conductive mounting bracket thermally coupled to the first container configured to conduct heat away from the LED, wherein an angle between the mounting bracket and the LED is adjustable to direct light from the LED in a new direction, and wherein a second container is thermally coupled to the LED, and wherein the second container contains a second phase change material having a second transition point temperature lower than the first transition point temperature of the first phase change material of the first container to account for a temperature drop between the second container and the first container.
