A new IC module lets LEDs operate flicker-free directly from 230 VAC line voltage, at power levels from 2 W to 70 W.
The German company Eurolighting has launched the IC EL01 module, which, with the addition of a few components, allows direct operation at 230 V -- with no flickering visible to the human eye. LEDs from various manufacturers can be employed.
The IC EL01 solves the filcker problem and operates more efficiently than switched power suplies, enabling reduced production costs. The IC EL01 rectifies the 230 VAC mains voltage and feeds it to an AC direct driver without the need for smoothing. Since no capacitors or inductors are required, except for interference suppression, the circuit board is much smaller than conventional solutions, and cheaper to make.
