0/1-10V led dimming is a process where the brightness of LED lights is adjusted by means of a dimmer. It works by controlling the amount of current flowing through the LED lights, allowing the brightness of the LED lights to be precisely controlled. This technology is used in a wide range of applications, including home lighting, stage lighting and commercial lighting. 0-10v and 1-10V are easily confused and are ALMOST the same thing. This is a supplementary article on Led dimming techniques.
What is 0/1-10V Led dimming?
0-10V Led dimming is a LED dimming technology used to control the brightness of LEDs. This technology works by controlling the voltage of the LED lights, allowing precise control of the brightness of the LEDs. 0/1-10V Led dimming technology is commonly used in commercial and industrial applications such as shops and offices, as it allows easy and precise control of lighting and can dim unlimited loads.
0/1-10V dimming for dummies like me
Imagine you have a lamp on your desk and you want to adjust its brightness. There is a lever on the lamp that you turn to change the brightness of the light. By turning the lever, a control device inside the lamp sends a message to the lights at different voltages.
Now think of the voltage (0-10V) as the car’s accelerator pedal. The more you give it gas, the faster the voltage travels and tells that light to burn brighter. If the throttle is at the bottom, then the light will burn at full power and with just a little throttle, it will light dimly.
0/1-10V dimming standards
There are two standards for 0-10V and 1-10V dimming, which are not compatible with each other. The difference is the control voltage: generating or carrying the control voltage. In other words, the 0-10V control type is “Current sink” or “Current source”. These standards are:
IES standard 60929 Annex E
The standard uses “current sinks”, which were initially used for dimming fluorescent tubes, but have recently been used in LED transformers.
“Current sink” means that the controlled device supplies voltage to the controller, but the controller reduces the voltage returned to the luminaires. In this standard, the light is at its maximum at 10 V and at its minimum if the restored voltage is less than 1 V.
Standard ESTA E1.3
This standard was used for dimming theatre lighting. The controller supplies a low voltage to the controlled device in “Current Source” control.
The controlled device adjusts the intensity of the lighting according to the voltage, scaling to a maximum intensity at 10 V and a minimum intensity at 0 V.
So compatibility problems arise if the dimmer sends a 5 V signal, the result may not be 50% of the original luminous intensity, but 30% or even 80%. This is also difficult to know before buying the parts.
What is the difference between 0-10 and 1-10V dimming?
The 0-10V dimmer has a built-in ON/OFF switch, but the 1-10V does not, so the light cannot be turned off completely.
Problems when combined
If the controller and dimmer are not compatible, the dimming range may be short or the light may flicker. Unfortunately, in most cases the only way to know is to test first. Connecting 0-10V dimmers to a 1-10V transformer causes problems such as flickering, stumbling and light flashing. Nor can the LED light switch off completely before the power supply is disconnected.
How does 0/1-10V Led dimming work?
0/1-10V Led dimming works by controlling the amount of voltage applied to the led lights. The dimmer controls the voltage, and the LED lights are connected to a dimmable transformer. When the dimmer is set to a certain voltage, the LEDs automatically adjust their brightness accordingly. This is achieved by sending a signal from the dimmer switch to the LED transformer, which then adjusts the voltage accordingly. Since the LEDs are controlled by current, when the current is reduced, the power flowing through the LEDs is also reduced. Therefore, dimming the light reduces power consumption.
For example, 0V is pitch black and 10V is bright. When dimming, the output current is 10% when the voltage is 1 V and 100% when the voltage is 10 V.
0/1-10V dimmer installation
When installing a 0/1-10V dimmer, you need to pull 2 wires from the dimmer to the light control. You will also need power to the led transformer and then connect the led lights to the transformer.
If you hear noise when dimming an LED light, pay attention to the wiring. It seems that the 0-10V DC lines are too close to the AC power lines and are causing noise. The problem occurs when 0-10V DC conductors run close to AC cables or are installed in the same conduit as AC cables. So make sure you use a shielded cable and that DC and AC cabling are routed separately.
Triac led dimming vs. 0/1-10V led dimming
Triac dimming and 0/!-10V dimming are two different techniques used to adjust the brightness of LEDs. They are often compared because both use low voltage to drive the LED.
Triac dimming works by switching the power on and off quickly, while 0-10V dimming works by controlling the voltage of the LEDs. So Triac dimming is more energy efficient than 0-10V dimming. This is because LEDs are not on all the time when they are dimmed, so they consume less energy. The 0/1-10V dimmer uses resistors to adjust the current of the LEDs, so some of the current is lost to heat.
What can 0/1-10V Led dimming be used for?
The 0/1-10V Led dimmer can be used in a wide range of applications such as home lighting, stage lighting and commercial lighting. For home lighting, the 0/1-10V Led dimmer can be used to create the perfect atmosphere in any room. In stage lighting, it can be used to create a more dynamic performance by controlling the brightness of the lights. In commercial lighting, it can be used to adjust the brightness of shop or office lights.
Advantages of 0/1-10V Led dimming
- Very easy to use: dimming requires very few settings.
- Highly accurate: allows very fine control of LED brightness.
- Cost-effective: requires little maintenance and is relatively inexpensive.
- No limits: because 0-10V dimming can be added to any size of LED transformer
0/!-10V Led dimming disadvantages
- Difficult to install: it may be because it requires extra wiring to the dimmer.
- Not as flexible as other dimming techniques: the voltage can only be changed in 1 volt steps.
- Poor compatibility: 0-10V has two standards that are not compatible with each other. This means that the dimmers may not work correctly with the controls.
- Noise problem: As control cables are often placed in the same duct as 230V cables, the dimmer may cause noise.
- Easy mixing: do not mix 0-10V and 1-10V dimmer and controller. It leads to flicker.
Finally
0/1-10V Led dimming is a LED dimming technology used to control the brightness of LEDs. It works by controlling the voltage of the LED lights, allowing precise control of the brightness of the LEDs. This technology is used in a wide range of applications, including home lighting, stage lighting and commercial lighting. It has several advantages, such as ease of use, accuracy and cost-effectiveness. However, it also has some drawbacks, such as difficulty of installation and compatibility.
