Lighting science | how to use LED lights to more electrical energy saving

Current advocate environmental protection, energy conservation, everyone hopes to create a low carbon society. So, how to do ability to let meters go slower? By the power department staff each position can be found below answer for you about LED lamp power consumption.

the problem, the LED light on all night spend how many money?

mr. li house model is small, are through the hall to the toilet at night, therefore, in the hall on the top of the suction with about 4 meters of the LED lamp belt, is 1 metre 60 bead, convenient to walk at night. As applied to the peak valley electricity, Mr Li going to open all night LED lighting. But his wife is very opposed, arguing that the LED lamp bead, small power consumption, open one night is not cost-effective.

power supply bureau shipment inspection maintenance monitor answer

common on the market of LED lights with 5050 tiles packaging format, this LED lamp bead work voltage is in commonly 3. 2 to 3. Between 4 v, the power is 0. 18 w - 0. About 2 w. A meter LED lights with 60 lamp bead, power consumption is in commonly between 9 w and 12 w.

Mr. Li's house have 4 meters LED lights belt, if you are open, the energy consumption of per hour up to 48 w, fluorescent lamp is slightly larger than an ordinary. If from 22 PM to 8 PM the next day, 10 hours, Mr. Li LED lamp with zero power consumption in the home. 48 degrees. According to the first ladder valley electricity 0. Price of 288 yuan/degrees, is about 0. 14 yuan.

problem two, closing the fluorescent lamp energy saving?

with miss Chen home hall of 40 w common fluorescent lamp, daylighting is bad, the old house used to open the lamp in the evening. Electricity in January after a copy, mother-in-law think small save electricity, from the hall into the kitchen for a few minutes, turn off the hall light.

but I heard that fluorescent lamp at startup current particularly big, frequent switch instead lose electricity, is it really the case? How much the door can save electricity?

power bureau power check class monitor answer

fluorescent lamp does appear at the moment of connected to an instantaneous high current, about 5 to 7 times that of normal working conditions. But the current changes in a very short time, the large instantaneous flow energy consumption generally equivalent to 1 millisecond under normal working power, energy consumption is negligible.

conclusion is fluorescent lamp is not power, but turn off the light or turn on the light to save electricity.

American science programs 'rumors terminator in the fourth quarter of 26 concentration have done detailed test, the conclusion is that unless a third in seconds to return to room, turn on the light or turn off the light than save electricity. Miss Chen and liking to show readers can see on the Internet.

but too frequently switch of life must have a certain influence.

miss Chen hall with 40 w common fluorescent lamp power, plus the inductance ballasts and 5 to 8 w power. If calculated on open five hours a night, energy consumption is 0. 24 kilowatt/hour, which is 0. 24 degrees. According to the first a ladder electricity price 0. 538 yuan/degrees, is about 0. 13 yuan. As for you want the door to save the money, it's miss Chen's own choice.
