For example: there are a lot of lights in a room, we have a set of 1-10V control lines less than 50 meters for each lamp, and connected to the controller. When the controller is adjusted, the voltage on the control line changes and the lamp is dimmed or dimmed.
The disadvantage of 1-10V dimming is that multiple sets of luminaires on a control panel can only change at the same time. If you want to achieve different control for each lamp, you can only have one-to-one correspondence between the control panel and the luminaire. When you get more, it will obviously become very troublesome to operate.
