Since the rise of LEDs as the preferred light source, accurate determination of their parameters has become crucial. One of these parameters – and a standard measure – is measuring LED light output versus current (L-I). Unfortunately, the result is not independent of other parameters. The environment, the package type and many other factors may distort the result. An article authored by Jeff Hulett, Vektrex, and Dr. Markus Schneider, OSRAM, explains in detail the basic problems that may be resolved with short pulse testing.
