Equipment description
To measure the thermal path in-situ a new test system has been developed at the research lab. The LED modules can be mounted on a temperature controlled heat sink which is temperature cycled between low (Tmin = -20°C), medium (TRT = +25°C) and high (Tmax = 125°C) temperature. In the combined operational live and temperature cycle test for a short time the LEDs are switched off and by TTA the Zth(t) is measured. Due to differences in thermo-mechanical stress under hot and cold conditions, additional information can be obtained. Target is to Tmax identify failures earlier by measuring at room, and Tmin.
