Analysis of LED lighting 1-10V dimming mode

1-10V

1-10V has two independent optical circuit device, a voltage circuit for the ordinary, for the power supply is switched on or off to the lighting equipment, the other is a low voltage circuit, it provides a reference voltage, tell lighting dimming level, 0-10V dimming controller for fluorescent lamps used in prior dimming control and now, because in the LED drive module with constant power supply, and a control circuit of the special, so 0-10V dimmer can also support a large number of LED lights.

However, the shortcomings of the application is also very obvious, low voltage control signals need to add a set of lines, which greatly improve the construction requirements.
