– LED lamp (typically 6 W)
■ RoHS compliant
Description
The purpose of the STEVAL-ILD003V1
demonstration board is to evaluate ST’s SCR
dimming solution for low-consumption lamps,
particularly CFL and LED lamps, eliminating
flicker, and to be able to directly test most
dimmable loads currently on the market.
Through-hole technology is used for the most
important components such as the LC filter, gate
resistor, turn-on delay capacitor, etc., in order to
allow board modification, if needed.
AC light dimmers based on SCR dimming
technology eliminate flickering as a continuous
current is applied through the gate. An SCR
dimmer could easily replace a standard low-cost
analog Triac light dimmer by using a Diac-
controlled circuit.
a. Higher power could be reached with a different filter
inductor and SCR heatsink.
