LED as a light source, LED lighting is very important. Not only to get a more comfortable environment in the home, but to reduce unnecessary electric light today, it is more important to further realize the goal of energy conservation and emission reduction. Moreover, for LED light sources, dimming is more easily realized than other fluorescent lamps, energy-saving lamps, high-pressure sodium lamps, etc. Therefore, it is more important to increase the function of light in all kinds of LED lamps.
The dimming mode of LED lamps(led lamp dimmer) usually includes the following: switch dimming, thyristor dimming, analog dimming, PWM dimming, and the following is a brief introduction to the characteristics of these modulated light modes.
The switch that move light
Switch that move light is through the original lamp power switch on the light, when using the installation does not need to add any dimmer, as long as constantly push the power switch of the number of original and speed can reach lighting lamps and lanterns that move light to meet the individual needs of different brightness.
This kind of dimming mode is the lowest cost in all dimming mode. When choosing, you can use only one switch to adjust the light fixture, and no additional installation charge is required.
The disadvantage of a simple switch dimmer is that it can only bring out three or four different levels of brightness, and it is not possible to adjust any brightness as a linear dimmer.
Silicon controlled dimming
The thyristor dimming mode is usually used to replace the original power switch with the thyristor dimmer switch to achieve different brightness through the rotary dimmer knob.
The advantages of this mode of dimming are simple and practical, and the overall installation cost is relatively low. Just add a thyristor dimmer, which is the most popular mode of dimming.
