ABSTRACT:
A luminaire using a tungsten-halogen lamp, includes a circuit for supplying the lamp with a boosted D.C. operating voltage. The circuit includes a full-wave rectifying circuit for receiving a standard A.C. mains supply voltage, and a low pass filter connected to the output of the rectifier. The value of the time constant of the filter is chosen to produce at the rectifier output, an average D.C. voltage of about between 135 and 146 volts, preferably about 140 volts.
