Power LED driver module (PLDM)
This year, for the first time, the efficiency of LEDs has overtaken that of fluorescent tubes. Power LEDs are thus now a realistic and energy-saving alternative to other forms of lighting. Getting them to light up, however, needs a bit of electronics, and hence the universal module described in this article.One thing is for sure: the twenty-first century will be the age of semiconductor light sources. This universal current source can drive up to eight white LEDs.
