FIELD: tool-making industry, in particular, engineering of devices for powering gas-discharge lamps with constant current from alternating voltage network.
SUBSTANCE: for achieving the result, controllable voltage transformer for powering gas-discharge lamp comprises serially connected controllable capacitive reactive resistor, making it possible to control power consumed by lamp in broad range and to control light stream. Lamp ignition voltage generator is made on basis of voltage multiplexer, inductive throttle, realizing function of accumulating reactor.
EFFECT: expanded functional capabilities.
