What's the dimmer?
2019-11-04
The purpose of a dimmer is to adjust the brightness of the led light. By reducing or increasing the RMS voltage to cause the average power of the light, then produced the different intensity light output. Although variable voltage devices can be used for a variety of purposes, dimmer mainly is intended to control lighting.

The scope of the dimmer is: small units of the normal light switch for home lighting, high power led drivers be used in the grand theater or architectural lighting. Usually small unit dimmers can be directly controlled, high power units need a remote control system. Modern professional dimmers generally use DMX or Ethernet digital control system.

In professional lighting industry, the strength changes of led power supply called"disappear",  " can disappear" or "disappear". Dimmers, manual control directly the number restrictions,  their speed can be different, but this problem has been basically eliminated in the modern digital forces (although the brightness changes speed is very fast may still can avoid other reasons which impact the lifespan of LED.
