Abstract

An automatic lighting intensity regulating device or "dimmer" (DM), utilizable in particular for electronic reactors of fluorescent tubes, controlled by an electronic circuit for the partial closing of the conduction angle, in order to supply a lamp current (IL), for each cycle of the rectified network signal (IR) , only for a certain amount of time, so as to minimize the production and operating costs of the device (DM), with respect to those now offered on the market.
