High-power remote-control dimmable high-voltage sodium lamp driver

Abstract

The invention is a high-power remote-control dimmable high-voltage sodium lamp driver comprising a filter rectifier circuit, an active power factor correction circuit, an HID small signal processing and protection circuit, a remote control module, a half-bridge inverter circuit and a pulse ignition circuit. The input terminal of the filter rectifier circuit is connected with 220-V commercial power and the output terminal of the filter rectifier circuit is connected with the active power factor correction circuit. According to the invention, on the basis of the two-stage-structure high-frequency drive circuit, an acoustic resonance problem is solved by chaotic modulation; with the STM32 control operation, connection or disconnection, gradient dimming, remote control, real-time monitoring and other functions of the high-voltage sodium lamp are realized; and the reliability of the drive circuit is improved and the energy is saved.

Description

technical field [0001] The invention relates to a driver, in particular to a driver for a high-power high-power sodium lamp that can be remotely controlled and dimmable. Background technique [0002] The existing high-pressure sodium lamp driving circuit is generally directly driven by a high-energy-consuming power-frequency inductor; there are common problems such as unadjustable power output of sodium lamps and difficult maintenance. [0003] 1. Equipment maintenance is difficult [0004] The daily maintenance of the equipment needs to be done manually, the workload is heavy, and the damaged equipment cannot be replaced in a timely and effective manner. When the equipment fails, it needs to be detected manually. Due to the high voltage, it is very easy to get an electric shock. [0005] 2. Low resource utilization [0006] The power factor is low, and the circuit consumes a lot of energy. It is relatively difficult to change the working power of the lamp, and the brigh...
