In order to ensure lighting-class white LED light is not only able to get a good application, but also higher efficiency, first you need to make it meet certain conditions, followed by the need to adapt the drive circuit to meet the the LDE working parameters to meet them .<\/p>\n

First, the application requirements of the LED lighting<\/p>\n

1, the driver circuit is powered by a specifically designed for LED special power supply, to have a simple circuit configuration, a smaller occupied volume, and a high conversion efficiency.<\/p>\n

2, the driving circuit of the output electrical parameters (current and voltage) to the technical parameters of the LED is driven match, to meet the requirements of the LED, and the constant current control with high precision, appropriate pressure limiting function. Multiple output, the output of each channel must be individually controlled.<\/p>\n

3, with linearity better dimming function, to meet the requirements of different applications of LED brightness adjustment.<\/p>\n

In an abnormal state (LED open circuit, short circuit, driver circuit failure), the circuit of the circuit itself, LED, and users have the appropriate protective effect.<\/p>\n
