There are currently two common driving methods: one is to use a constant voltage source to supply multiple constant current sources, and each constant current source supplies power to each LED separately. This method is flexible in combination, and if one LED fails, it will not affect the operation of other LEDs, but the cost will be slightly higher. Another method is direct constant current power supply, with LED series or parallel operation. Its advantage is that it has a lower cost, but its flexibility is poor. It also needs to solve the problem of a certain LED failure without affecting the operation of other LEDs. These two forms coexist for a period of time. The multi-channel constant current output power supply method will be better in terms of cost and performance. Perhaps it will be the mainstream direction in the future.

Mainly for LED spotlights, LED light strips, LED street lights, LED light bulbs, LED underground lights, LED ceiling lightsLED flat panel light、 LED wall washers and other LED lighting fixtures provide driving capabilities. Its important feature is waterproof, which can be used outdoors without fear of harsh environments such as rain, fog, and direct sunlight.
