The apparatus has a first printed circuit board with optoelectronics and electronics located on a thermoelectric cooler. The thermoelectric cooler is located on a second printed circuit board that also has electronics that control the thermoelectric cooler separately mounted thereon. The optical module operates at substantially higher temperatures by placing the optoelectronics and the electronics, not including the thermoelectric cooler controller, on the thermoelectric cooler. The electronics controlling the thermoelectric cooler only require relatively simple, low-speed electronics that are implemented in integrated circuit technologies. The integrated circuit electronics may operate at very high temperatures (200° C. or higher) thereby making control of the thermoelectric cooler with uncooled electronics possible.

  • Patent number: 8123389
    Abstract: A lighting system is described. The lighting system includes a lamp and a first container including a first phase change material thermally connected to the lamp. Heat generated by the lamp during operation is conducted to the first phase change material. The system also includes a second container including a second phase change material thermally connected to the lamp. Heat generated by the lamp during operation is also conducted to the second phase change material, and the second phase change material has a transition point temperature lower than the 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. The lighting system also includes a temperature sensor for reducing lamp power if the lamp becomes too hot, and a mounting bracket which may also conduct heat away from the lamp.

  • Patent number: 8066417
    Abstract: Different arrangements for improving the coupling-in efficiency between an LED assembly and a light guide are disclosed. In a first arrangement, a substantially planar end of a light guide is seated on a perimeter wall of a support that encloses a LED assembly, and a reflecting surface enhances coupling efficiency of a light guide. Alternative arrangements use a separate coupler disposed between the LED assembly and the light guide, which coupler has a paraboloid or aspheroid conformation to develop substantially collimated light that is directed into the light guide. The cavity around the LED assembly and within the coupler, may be air or a material having an index of refraction that closely matches the index of refraction of the light guide material.
