LIGHTING CONTROL SYSTEM Russian patent published in 2023 - IPC H05B47/185 H05B45/00 H05B47/20 

FIELD: lighting control systems.

SUBSTANCE: lighting control system contains a controller and a phase voltage regulator connected to it, designed to transmit control signals through power electrical circuits. The controller and the phase voltage regulator are installed in the electrical distribution cabinet of the lighting line. Also, the lighting control system has at least one lamp connected to the lighting line and based on an LED driver and a microcontroller. The input interface of the microcontroller is connected to the power line of the corresponding lamp, as well as to the analogue-to-digital converter through galvanic isolation. In addition, the microcontroller contains a digital filter unit, the output of which is connected to the inputs of the synchronizing pulse detector module, the pulse duration meter module, and the threshold comparator module. In this case, the outputs of the pulse duration metering module and the threshold comparator module are connected to the inputs of the data analysis unit, the output of which is connected to the input of the control unit. The control unit is configured to determine and transmit the reference voltage value to the comparison register of the threshold comparator module of the microcontroller. In this case, the output of the control unit is connected to the input of the PWM module, which in turn is connected through galvanic isolation to the LED driver interface. In this case, if the control unit receives a signal corresponding to an error signal, as well as if a malfunction is detected in at least one hardware element, the control unit resets the calculated data of the current state, and the LED driver switches to the mode of producing the maximum brightness of the lamp.

EFFECT: provision of a lighting control system organized by power electrical circuits.
