Why does turning the light on and off more frequently consume more energy than leaving the light on all the time?

This problem is just like what is said online about turning off the lights and wasting electricity. It may be that high-frequency switches will damage the switches or short-circuit the lights. A short circuit may not necessarily break it, but it will definitely consume electricity. .

Many people will develop the good habit of turning off the lights at will after coming out of school! But is it really good to turn the lights on and off? People have always suspected that frequent switching of lights is time-consuming and consumes the life of switches and lights. Many people develop the good habit of turning off the lights at will after coming out of school! But is it really good to turn the lights on and off? People have always suspected that frequent switching of lights is time-consuming and consumes the life of switches and lights. Turning lights on and off frequently not only consumes the life of the switch, but also wastes more electricity each time. Due to frequent switching of lights, the switch may be damaged or accidentally short-circuited. In general, pressing the switch frequently will increase the wear of the switch, so if the light is used frequently for a long time, there is no need to turn it back and forth.

Of course, it is not ruled out that turning off the lights can save more electricity. Now we can basically see the slogan "Turn off the lights at will" in public places, so after everyone's experience, we have naturally formed the habit of turning off the lights at will. We believe that the power must be turned on when turning off the lights, so we turn off the lights at will. You can save a little bit to a certain extent.

I think this should be related to the type, time and frequency of the light. Decide whether to turn off the lights at will based on actual usage. There are many types of lamps such as incandescent lamps, fluorescent lamps, energy-saving lamps, and induction lamps. Generally speaking, the cost of turning off fluorescent lamps and energy-saving lamps at will is higher. Fluorescent lights use a lot of electricity every time they are turned on. Fluorescent lights are generally not used in homes these days. If you use the light for a long time or use it frequently, try not to turn off the light at will. If you are only leaving temporarily, you don’t have to turn off the lights at will. Such a back and forth switch requires a lot of hassle, and it may also consume the life of the switch and light.
