Working principle and dimming technology of DC dimmers:
DC dimmers change the brightness of the light source by adjusting the current or voltage. Its core function is to achieve voltage conversion and stable current control. Common dimming technologies include PWM (pulse width modulation) dimming and linear dimming. PWM dimming adjusts the average current of the LED by changing the duty cycle to adjust the brightness; while linear dimming directly controls the current flowing through the LED by changing the input voltage or the resistance of the current detection resistor to achieve linear changes in brightness
Advantages of DC dimmers:
1.No flicker and no noise: Using advanced PWM control technology to eliminate flickering, reduce noise, and provide a comfortable and stable lighting environment.
2.High efficiency: DC dimmers have the characteristics of high efficiency, high reliability and long life.
3.Multi-channel common anode: Supports the driving of multiple LED lamps to achieve more flexible and diverse lighting layouts.
4.Precise dimming: The dimming accuracy is as high as 0.1%, making the brightness adjustment of the LED more delicate and achieving the ultimate visual effect.
DC dimmers with drivers are generally used in the following scenarios:
Indoor lighting : Lighting systems in homes, offices, shopping malls and other places provide a comfortable and healthy lighting environment
Outdoor lighting : Road lighting, landscape lighting, square lighting, etc., to enhance the city image and beautify the living environment
Automotive lighting : In-car lighting, exterior lighting, etc., to improve driving safety
Stage lighting : Meet the lighting needs of performances, celebrations and other activities, and create colorful visual effects
Advertising display : LED display screens, billboards, etc., to attract customer attention and enhance brand image
Smart lighting : Combined with the Internet of Things technology, remote control, scene switching and other functions are realized to enhance the intelligence level of the lighting system
