The characteristics of the LED has a very important -
Dimming, this feature is superior to the other light sources, but its technical difficulty is quite high.
LED dimming method is one of the commonly used PWM PWM dimming, the power supply into pulse constant current source, by changing the method of pulse width, and control the square wave duty ratio, to adjust the brightness of LED.
PWM dimming can ensure that the LED has been between 0 and full picture of current work, so this method will not produce the LED color deviation.
At the same time, the method that move light precision is very high, can realize the accuracy of up to one over ten thousand.
PWM dimming can also achieve smooth move light over a large area, does not occur.
Most engineering approval is the dimming method can better compatible DALI, DSI, DMX512 digital control technology, the LED dimming into digital lighting control system.
Now it has many engineering applications.
Constant current power supply control is also LED dimming methods which are frequently used, its principle is to use linear simulation technology can adjust the size of the current, so as to realize the dimmer.
Dimming effect and 'side effect', this method is much less than the PWM dimming.
Electric light up every inch of space for everyone, we can according to customer requirements and the actual use of the environment, customized products and provide integrated solutions for customers, for the general customers to provide quality and efficient products.
