DEVICE FOR CONTROLLING GAS-DISCHARGE LAMP Russian patent published in 2008 - IPC H05B41/233 

FIELD: illumination.

SUBSTANCE: invention relates to the means of controlling the gas-discharge light sources. The device for controlling the gas-discharge lamp consists of the microprocessor (2) controlled generator (3) of the ignition impulses and the single-step transducer (9). The generator (3) includes the current source (23), capacitor (24) which is plugged in parallel to (23), power key (5) and the first transformer (7) winding (6) at the closed core (25). The leads of the second transformer winding (8) are closed at the leads of the lamp (1). The transducer (9) contains the power key (11) connected with the electromotive force source (10), and the parallel resonant circuit (12) which includes the serial choke (15) and the third transformer (7) winding (13). The fourth transformer (7) winding (14) is connected via choke with the microprocessor (2) controlled current source (17) which controls the lamp current without frequency modifications, due to the magnetic elements included in the device.

EFFECT: controlling characteristic of device is extended.
