LED-81x

 

Due to a low electrical power requirement of only several watts, high-power LEDs do not only generate high light output. The thermal dissipation associated with this power load, however, leads to considerable warming of the LED chip and packaging, so this energy has to be properly dissipated in order to guarantee the specified LED lifetime and to avoid failure. Chip temperature also affects the emitted optical power and the emission spectrum (color).The higher the temperatures the lower the amount of light generated.

Instrument Systems has two ranges of test sockets for reliable operation of high-power LEDs - LED-81x series with passive cooling and LED-850 series with active cooling/heating via a thermoelectric cooler element. Sturdy contact pins enable reliable electrical connection to the LEDs.

Features

  • passive cooling with thermal sink and fan
  • suitable for LED adapters with 25 mm Ø
  • PT100 temperature sensor
  • 5 W maximum LED thermal dissipation
  • 2 A maximum drive current

LED-81x series of test sockets can reliably handle high-power LEDs up to 5 watts of thermal dissipation. They are constructed in such a way that the generated heat is quickly transported away from the LED and into the surrounding air (fan assisted). To monitor temperature, a PT100 sensor is integrated and can be read using a compatible device. The LED-81x series test sockets are optimized for a particular high-power LED packaging type.
