Abstract

The invention belongs to the technical field of LED drivers, and particularly relates to an LED driver circuit and a working method thereof. The LED driver circuit comprises a driving circuit, a standby detection control circuit and an intelligent controller which are connected in sequence. The driving circuit is used for correcting and converting alternating current input by a power grid, outputting direct current and driving an LED lamp to be turned on or turned off. The standby detection control circuit is used for adjusting the power of the driving circuit according to a received dimming control signal. According to the invention, when the LED lamp is in a standby state, the standby detection control circuit adjusts the power of the driving circuit according to a dimming control signalsent by the intelligent controller, so as to reduce the power of the driving circuit and reduce the overall power of the LED driver circuit. Therefore, the standby power consumption of the LED lamp is reduced, electric power resources are saved, and the service life of the LED lamp is prolonged.

Description

technical field [0001] The invention belongs to the technical field of LED drivers, and in particular relates to an LED driver circuit and a working method thereof. Background technique [0002] All LED lighting lamps need LED drivers, which are power adjustment electronic devices used to drive LEDs to emit light or LED module components to work normally. The current power frequency power supply and common battery power supply are not suitable for directly supplying LEDs. LED drivers are electronic components that can drive LEDs to work in the optimal voltage or current state. [0003] LED drivers generally include a power factor correction circuit, an auxiliary power supply circuit, a dimming circuit, a DC-DC conversion circuit and a control module circuit. When the high-power LED lamp is in the standby state, the LED is turned off, and the LED driver continues to work, that is, the auxiliary power supply circuit continues to stand by and supplies power to the control modu...
