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, about 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). In other words, true dimming can be adjusted from brightness and color temperature.
At present, there are two types of ceiling lamps that can adjust the LED color temperature on the market. One is fixed brightness and only three color temperature (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.
KNLE2-63 Residual Current Circuit Breaker With Over Load Protection
KNLE2-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
