ACTUATOR FOR SOLID-STATE LAMP

摘要

FIELD: electricity.SUBSTANCE: invention relates to lighting engineering. An electronic actuator (100) for solid-state lamp start-up is designed to receive the alternating-current voltage with the phase cutoff; receive from the alternating-current voltage with the phase cutoff of data on light regulation that defines the required level of light regulation at the lamp output; start up the solid-state lamp in the light-regulation mode at the level of light regulation corresponding to the required level of light regulation received from the alternating-current supply voltage with the phase cutoff. The actuator record input current; it comprises a lamp current control generator (130); a control device that controls the lamp current control generator, a rectifier (110) that rectifies the received alternating current supply voltage with the phase cutoff; a current sensor (150) that records an output current of the rectifier; a signal processor (160) that processes an output signal of the current sensor and generates an input signal for the control device (140).EFFECT: regulation of light intensity.9 cl, 13 dwg
