Description
技术领域technical field
本发明是一种LED路灯的驱动电路，属于LED灯设备领域。The invention is a driving circuit of an LED street lamp, which belongs to the field of LED lamp equipment.
背景技术Background technique
LED电路是一种能够将电能转化为可见光的半导体，它改变了白炽灯钨丝发光与节能灯三基色粉发光的原理，而采用电场发光。在需要使用比较多的LED产品时，如果将所有的LED串联，将需要LED驱动器输出较高的电压:如果将所有的LED并联，则需要LED驱动器输出较大的电流。将所有的LED串联或并联，不但限制着LED的使用量，而且并联LED负载电流较大，驱动器的成本也会增加，解决办法是采用混联方式。串、并联的LED数量平均分配，这样，分配在一个LED串联支路上的电压相同，同一个串联支路中每个LED上的电流也基本相同，亮度一致，同时通过每个串联支路的电流也相近。The LED circuit is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament luminescence of incandescent lamps and the three-based toner luminescence of energy-saving lamps, and uses electric field luminescence. When more LED products need to be used, if all the LEDs are connected in series, the LED driver will be required to output a higher voltage; if all the LEDs are connected in parallel, the LED driver will be required to output a larger current. Connecting all the LEDs in series or in parallel not only limits the usage of LEDs, but also the load current of the LEDs connected in parallel is relatively large, and the cost of the driver will also increase. The solution is to use a hybrid connection. The number of series and parallel LEDs is evenly distributed, so that the voltage distributed on one LED series branch is the same, the current on each LED in the same series branch is basically the same, and the brightness is consistent. At the same time, the current passing through each series branch Also close.
