Patent ID: 8882276

Claim:
A projector assembly comprising: a first light assembly having a top surface, a bottom surface, a first surface, and a second surface opposite the first surface, the first light assembly including a first light source; a second light assembly having a top surface, a bottom surface, a first surface, and a second surface opposite the first surface, the second light assembly including a second light source, wherein the first surface of the first light assembly is adjacent to the second surface of the second light assembly, wherein each light source has a top surface and a bottom surface opposite the top surface; a first fan of a pair of fans for each light source, the first fan aligned with the top surface of the light source for supplying air to the top surface, wherein a first speed of the first fan is variable; a second fan of the pair of fans for each light source, the second fan aligned with the bottom surface of the light source element for supplying air to the bottom surface, wherein a second speed of the second fan is variable; a temperature measuring device adapted to determine an ambient temperature; and control circuitry adapted to adjust the first speed of the first fan and the second speed of the second fan based on the measured ambient temperature to reduce a temperature difference between the top surface of each light source and bottom surface of each light source.
