The photometric specifications of LEDs must meet very high tolerance requirements regardless of whether they are to be used in general, automotive or other specialist lighting applications. This is often a problem since the manufacturing tolerances of LEDs can be higher than those permitted in the end-use applications. Also, LED binning by LED manufacturers in order to classify LEDs based on their tolerances is performed with flash mode testing using pulsed current flow. However, end-use applications of the LEDs often operate in constant current mode and with significant thermal effects....

through a metal adapter that is specifically designed for the respective LED. The LEDA-7-TEC spectral radiometer LED socket is fully remote controlled. Electronic supply and measurement system Power supplies from the Keithley 2400 series are used to supply test LEDs in pulsed and constant current modes (max. 60 V, 3A, and 60W). Their source meter function allows for simultaneous measurement of electrical parameters according to DIN 5032-9, LM-79-08, and CIE S025. As for the pulsed mode, the light meter and source meter are connected to an extra trigger line for time-synchronization. Current...
