Five ways to dim LED lighting

Nowadays, most LED lighting problems are caused by the mismatch between the control system and the light source appliances, which has become a common problem in the industry. At the same time, the diversification of LED lamps and lanterns also put forward a higher challenge to the control system. The LED light-emitting principle is different from traditional lighting. It is by P-N junction light, and the same power LED light source; the current and voltage parameters are different because of the other chips used. Hence, its internal wiring structure and circuit distribution are also different, resulting in the light source of the manufacturers of dimming drive requirements are not the same. If the control system and lighting equipment do not match, it may cause the lights to go out or flicker and may cause damage to the LED lighting driver circuit and light source.

There are five types of LED lighting equipment control methods on the market.
　　1, leading-edge phase cutting (FPC), silicon controlled dimming
　　2, trailing edge phase cutting (RPC) MOS tube dimming
　　3, 1-10VDC
　　4, DALI (digital addressable lighting interface)
　　5, DMX512 (or DMX)
