Using LEDs: drivers and dimming
Keywords:light emitting diodes, LED, UV-A, UVB, led dimming, PWM dimming, CC dimming, Yoctopuce
In this article I describe how currently available LED drivers and computer interfaces make it easy to build custom light sources. In particular stable light sources with easely repeatable settings useful for photobiological experiments and scientific photography. I also describe alternative approaches to dimming LEDs and the current availability of ultraviolet LEDs and their characteristics.
