摘要
A transformer (5) for variable input voltages has safety cutout circuit (SCC) for protecting a lamp (4) from overload. The SCC has a control device for pulsed connection of the lamp's voltage with pulse-width modulation. The CD switches and regulates the lamp's voltage supply according to brightness via a light pick-up device and a comparator circuit with preset brightness threshold values.
