Power LEDs get their dedicated thermoelectric cooling unit
14.00
They are designed for applications where temperature stabilization of sensitive optical components is critical. The use of the circuit board improves the heat pumping capabilities of the device while providing excellent heat spreading, improved reliability and lower cost in high volume when compared to traditional heat removal systems.
Tlam is used in applications where the components in the circuit produce a lot of heat, such as high powered LEDs, power supplies or motor drives. The Tlam circuit boards feature a thin layer of thermally conductive dielectric material sandwiched between a top layer of standard copper foil and a thick metal backing plate for structural strength and improved heat spreading. The combination of the Tlam circuit board with the thermoelectric offers a completely new way to design thermal rejection systems and can reduce the complexity of moving heat away from sensitive devices.
The Tlam OptoTEC series includes seven new modules that can create a temperature differential (ΔT) of up to 67°C and pump from 1.5 to 9.0 watts of heat at an ambient temperature of 25°C. At 85°C, the series can create a ΔT of 77°C and pump 1.6 to 9.9 watts of heat.
