Segmented switch dimming
A company in Taiwan has launched a four-segment switch dimming called EZ-Dimming GM6182 is a good solution. It can achieve 4-stage dimming using only the ordinary light switch on the wall. The first time is full brightness, the second time is 60% brightness, the third time is 40% brightness, and the fourth time is 20% brightness. brightness. The advantage of this system is that it can be dimmed using ordinary wall switches. And its power factor is as high as 0.92 or more. There is no concern about interference signals. The disadvantage is that continuous dimming is not possible. There are also some troublesome operations.
4.3 Remote dimming
Using infrared remote control to achieve dimming of LED. This is of course the most ideal solution. Can switch lights, and continuous dimming with PWM. The disadvantage is that the cost is high, there is no uniform specification, it can only be used for high-end residential.
