Passive cooling with heat sink and fan Models for all common high-power LEDs PT100 temperature sensor Maximum LED power rating of 5 W We BrInG QuALIty tO LIGHt Test Sockets for High-Power LEDs High-power also means high-temperature High-power LEDs pose a real challenge to users implementing lighting applications. But these high-wattage LEDs do not only generate high light outputs. The associated power dissipation also leads to a massive temperature rise in the component. The LED must be protected by suitable thermal management in order to prevent significant shortening of its service life or even its destruction. What‘s more, the temperature of the LED chip has an enormous influence on the light output emitted and on the radiation spectrum (LED color). The higher the temperature, the lower the light output.

Reliable operation of LEDs with the LED-81x test sockets Test sockets from the LED-81x series enable high-power LEDs with wattages of up to 5 W to be operated reliably and safely. These sockets have been designed such that the heat generated at the LED is quickly dissipated to the ambient air. This effect is assisted by a fan. A PT100 sensor – whose measurements can be read out at a suitable metering device – is integrated to monitor the temperature. Design, Centering cap concept, Mechanical functionalities The LED-81x test sockets with passive cooling are optimized for one particular type of...

The heat load at the LED is dissipated by means of a gold-plated copperzirconium rod which houses a PT100 temperature sensor. The sensor is positioned immediately below the contact surface for the test sample and in this way ensures maximum measuring accuracy. The high thermal conductivity of the copper-zirconium rod and the built-in fan ensure efficient cooling of the LED and protect the LED against being destroyed when ambient temperatures are high. The test sockets can be used under ambient temperatures ranging between 15 and 35°C. Precise contacting using the 4-wire system Electrical contacting...
