Rear-mounted LED dimming control device and method

Abstract

The invention relates to the technical field of IoT (Internet of Things) and illumination, and discloses a rear-mounted LED dimming control device. The rear-mounted LED dimming control device comprises a rear-mounted LED dimming control device; and a wide-voltage DC (Direct Current) power supply interface is fixedly mounted outside the left side of the rear-mounted LED dimming control device. Therear-mounted LED dimming control device and method, by a built-in backup power supply management module, solve a problem of unstable output of 0 to 10V, which is caused by conversion of a DC voltage output by a LED power supply in the 0-10V dimming process, avoid lamp flicker caused by feedback in the dimming process, have an input and output voltage and current sampling function, and can completeload detection of a LED lamp; in the dimming process of the LED lamp, a wide voltage output by a power supply under the drive of the LED lamp can be changed; and in the changing process, an independent power supply system in a dimming control feedback module can ensure that a signal output in the dimming process is stable and cannot be changed along with conversion of the power supply voltage, soas to avoid a stroboflash problem in the dimming process.

Description

technical field [0001] The invention relates to the technical fields of the Internet of Things and lighting, in particular to a rear-mounted LED dimming control device and method. Background technique [0002] In the field of Internet of Things and lighting, there are a large number of LED lighting fixtures. These lighting fixtures are powered by AC 220V power supply to realize space and area lighting. The power consumption of hundreds of watts, the lamps are still powered on when there is no personnel activity, and still consume electric energy, which cannot achieve the purpose of further energy saving and environmental protection. The lighting controller is added between the power supply to realize the remote switch control of the lighting and the adjustment of the brightness of the lighting. Although the remote control of the lighting is solved to a certain extent, the AC 220V used in this front-mounted lighting controller Voltage power supply, the power supply voltage i...
