Fast and precise test of high-brightness LEDs with a source measurement unit (SMU)

Nowadays the use of white high-brightness LEDs (HBLED) is gradually becoming more popular. It can be easily explained with their efficiency and durability as well as ecological compatibility. White HBLEDs are so widely used due to their significant technical advantages and electric specifications. The present article describes the method of fast and precise measurement of such white HBLED specifications using a source measurement unit (SMU). Such Agilent SMUs, for example, B2900A series source measurement units, have various features which allow testing and measuring the parameters of both standard and high-brightness LEDs.
