Design Of An 8-Channel Data Acquisition System For Measuring Diode Junction Temperature, Jason Maynard

Industrial and Manufacturing Engineering

The solid state lighting industry is striving to expand the use of light emitting diodes (LEDs) in more applications, particularly in high brightness applications. As the power of LEDs increase, heat removal becomes a critical issue. To improve device lifetime, quantum efficiency, and LED colour, the diode p-n junction temperature (Tj) must be kept to a minimum. Measuring this key parameter is difficult or impossible with direct methods, such as thermocouples and infrared cameras, due to the small size of LEDs. Fortunately, junction temperature can be measured indirectly by using a relationship between the diode forward voltage (Vf) and junction …
