[1] It is a device that converts alternating current into direct current through a transformer and a rectifier. This device is called a rectifier power supply, also called a driving power supply. An electronic device that can provide a signal is called a signal source. Lithium batteries, dry batteries, rectified power supplies, and signal sources are sometimes called power supplies.
The main difference is: the LED power supply is a constant current source, and the general switching power supply is a constant voltage source.
LED power supply features:
1. The requirement must be cross-flow.
2. Low temperature, low heat and long life.
3. Small size.
4. Waterproof, anti-corrosion and anti-static.
5. High frequency pollution.
LED power supply is widely used in street lights, tunnel lights, LED floor tiles, LED point light sources, LED grill lights, LED interior lights, LED ceiling lights, buildings, roads and bridges, square construction facilities, lawn lights, curtain wall lights, LED wall washers, table lamps Hotels, stadiums, etc.; information plane displays include LED displays, display panels, dynamic billboards, analog animations, stadiums, indicator lights in the carriage and internal reading lights, brake lights outside the car, tail lights, turn signals, side lights, explosion-proof lights Lamps, miner's lamps in mining production, etc.
