Abstract
A lighting assembly includes a cooling system configured to enable the dissipation of a large amount of energy in the form of heat generated by a light source. The cooling system is configured as a gravity feed cooling loop that does not require a powered fluid pump. The light source can be a plurality of LEDs mounted on a printed circuit board (PCB). The PCB is aligned and mounted vertically onto an evaporator. The evaporator is configured to enable the vertical alignment of the PCB and to cool the PCB while in this vertical alignment. The vertical alignment of the PCB enables horizontal projection of light emitted by the LEDs, such as in an automotive headlight application.
