What Is 0-10V Dimming For LED Lights?

The 0-10V dimming is a common technology used to control the brightness of lights. It realizes the dimming control of the light by sending different voltage signals. This post will introduce the principle and application of 0-10V dimming scheme.

 

0-10V Dimming Principle

  • 0-10V dimming is an analog dimming method. It controls the output current of the power supply by changing the voltage of 0-10V to achieve the dimming function.
  • This dimming method has two more 0-10V interfaces (+10V and 0V) on the power supply. When the voltage is 10V, the lamp is the brightest; when the voltage is 0V, the lamp is off.
  • In addition, the 1-10V dimmer only has one 1-10V interface. When the resistor dimmer is adjusted to the minimum 1V, the output current is 10%, and at 10V the output current is 100%.0-10V dimming-Beon

How about 1-10V Dimming?

There is also 1-10V on the market, so what are the differences between 0-10v and 1-10v dimming?
The main reason is that the lighting and turning off voltage of the lamp are different. 0-10V lights up when the voltage signal is 0.3V, and turns off the output of the lamp when the voltage signal is lower than 0.3V; while 1-10V lights up when the voltage signal is 0.7~0.8V, and when the voltage signal is lower than 0.3V, the output of the lamp is turned off. Turn off the lamp output at 0.6V.

 

 

For Example, Taking BA-509N7-150M as an example, its appearance differs from ordinary drive power supplies in that there are two more signal control lines at the output end. The 0-10VDC dimming LED driving power supply currently sold on the market can not only use 0-10 V control signals, but also use 10 V PWM or resistors for dimming.

0-10V Dimming LED Lights

 

0-10v is divided into two schemes of constant voltage and constant current:

1, Constant current 0-10v dimming led driver: mainly used for dimming applications of down lights, panel lights and other lamps, constant current output, multi-current support, no requirement for voltage, high conversion efficiency, smooth dimming curve without flicker.

2, Constant voltage 0-10v dimming led driver: mainly used for constant voltage LED lamps such as light bars, light strips, MR16, etc., constant voltage output, supports dimming curve customization, and is widely used.

0-10V Dimming Driver Application

 

0-10V dimming is widely used in commercial and industrial settings, especially with LED fixtures equipped with dimmable drivers. It is a popular choice for offices, retail spaces, and other environments where precise and smooth dimming control is required.

Additionally, lighting for retail, office buildings, entertainment venues, theaters, or any commercial space with dimming-compatible LED fixtures can be effectively dimmed using this system. 0-10V dimming can also be used for outdoor commercial applications that require multipurpose lighting.

The easiest way to control lighting is with 0-10V dimming, which allows for smooth operation and dimming down to 10%, 1%, and even 0.1% light level. At 10 volts, the light will be at its brightest. At 0 volts, the light will dim to its lowest level, but a switch is sometimes needed to turn it off completely.

How to use 0-10V dimming driver on LED street light/Intelligent street light?

 

The intelligent single light controller is connected to a 0-10V dimming led driver, Than can supports PLC power carrier or LoRa wireless network, to form a light control network system. Remotely control the “on-off” status of street lights in different areas through the web terminal, customize the ratio of midnight light brightness output, automatically switch lights on and off and automatically dim, collect data every 10 minutes, and monitor the working status of street lights in different areas in real time.

How to use 0-10V dimming driver in Tunnel Light?

Tunnel lighting

0-10V dimming of LED tunnel lights is a common and widely used dimming method. The principle of this dimming method is to control the brightness of the LED tunnel light by changing the size of the voltage signal (commonly used are 0-10V or 0-5V, we take 0-10V as an example). The following will introduce the 0-10V dimming principle of LED tunnel lights in detail.

Basic principle:

The 0-10V dimming principle of LED tunnel lights is based on the control method of voltage signals. When the voltage output by the controller is 0V, the LED tunnel light goes out; when the voltage output by the controller is 10V, the LED tunnel light reaches maximum brightness. There are also inverse proportional dimming designs, with 0V corresponding to maximum brightness and 10V corresponding to off. Regardless of whether it is a direct proportional or inverse proportional design, the brightness of the LED tunnel light can be adjusted by changing the voltage value output by the controller.

Wiring method:

0-10V dimming of LED tunnel lights requires the use of a specific dimmer (dimming driver) and controller. Generally, the input end of the dimmer is connected to the mains, and the output end is connected to the LED tunnel light; the controller is connected to the dimmer through a dimming signal line. The controller controls the brightness of the LED tunnel light by changing the voltage signal on the dimming signal line.

Dimming range:

The 0-10V dimming range of LED tunnel lights is 0-100%. When the voltage output by the controller is 0V, the LED light goes out; when the output voltage is 10V, the LED light reaches maximum brightness. By changing the output voltage, any brightness adjustment can be achieved within the dimming range.

Control method:

0-10V dimming of LED tunnel lights can be achieved through manual control and automatic control. Manual control can change the voltage value output by the controller through a knob or switch; automatic control can be achieved through external sensors or intelligent control systems to automatically adjust the brightness of the LED light according to changes in ambient light or a preset dimming scheme. Ambient lighting parameters are generally collected through brightness collectors, which are set up outside the tunnel, at the entrance and in the basic lighting section.

Advantages and applications:

The 0-10V dimming principle of LED tunnel lights has the advantages of wide dimming range, high dimming accuracy, and simple control, and can achieve stepless dimming. This dimming method is widely used in tunnel lighting, indoor lighting, landscape lighting and other fields to meet the needs for light brightness in different scenarios.

Summary:

The 0-10V dimming principle of LED tunnel lights is a common dimming method, which controls the brightness of LED lights by changing the size of the voltage signal. This dimming method is widely used and has the characteristics of wide dimming range and high dimming accuracy. It provides a simple and effective solution for lighting control of LED tunnel lights.
