The reason why LED ceiling lamps can achieve dimming is mainly because it has two channels of output inside. All the way is warm light (about 3000k color temperature), all the way is cold light (white, 7000k color temperature). Every road is independent. By giving each channel a different brightness, it is possible to adjust the color temperature and adjust the brightness of the entire lamp. For example, road A is warm light, color temperature is 3000k, but the brightness is only 10% of full brightness, while road B is cold light, brightness is only 40% of full brightness, then the color temperature mixed in the lamp body may be only 5000k (not very Cool white, there is also a little warm white). That is to say, true dimming can be adjusted from brightness and color temperature.
At present, there are mainly two types of ceiling lamps that can adjust the color temperature of LEDs. One is fixed brightness and only three colors (warm white, neutral white, and white), which is cheap; the other is called no. Level adjustment, such as PI-TECH dimming color ceiling lamp, brightness and color temperature can be adjusted independently, each of 10 gears, with up to 100 effects, remote control through the remote control. This price is more expensive, about 200 yuan.
The above is the secret of some ceiling lamps that can adjust the color temperature of LEDs. In fact, the principle is very simple, it is not difficult to understand, you can reserve it as a small knowledge, or identify the product you want from the products recommended by the sales staff when purchasing LED ceiling lamps.
