LED is famous for energy saving. The power consumption of a single LED lamp is indeed very low. However, when millions of LED lamps are gathered together to make LED display, the power consumption can not be underestimated.
LED is famous for energy saving. The power consumption of a single LED lamp is indeed very low, but when millions of LED lamps are gathered together to make LED display, the power consumption can not be underestimated.

Is led display energy saving


take the outdoor advertising screen of 200 square meters.
P10 as an example:
generally, the maximum power consumption is calculated according to the number of points,
LED lamps generally use 5V voltage and 20mA current, so the power of a group of lamps is 3 * 5 * 0.02=0.3w,
P10 full color, The average power consumption is about half of the maximum power consumption,
so it is about 375 W,
converted into electricity consumption. According to 14 hours per day (8 a.m. - 10 p.m.), 14 * 375 w=5.25 kW / h=5.25 degrees,
industrial power consumption is generally 1 yuan / degree,
so the power consumption per square meter is 5.25 yuan,
The daily electricity charge of 200 square meter LED large screen is 5.25 * 200=1050 yuan,
in a year, 365 * 1050=383250 yuan.


for the media owners of LED large screen.
no matter what the advertising revenue of large screen is, the electricity charge generated by the operation of LED large screen every year is a fixed expenditure, This is totally different from the traditional spray painting or three sided advertising.
in the face of high electricity charges.
how to use the large LED screen to save electricity

of course, the energy saving of LED display comes from the manufacturers of LED display, such as the luminous efficiency of LED lamp, the design of PCB, the selection of driving IC, the selection of power supply, the design of screen heat dissipation, etc,However, these factors can not be changed in the operation process of LED display.


for large LED screen owners,
scientific and reasonable use can also achieve more energy-saving effect.
in terms of playing content,
white screen consumes more power than other pictures, avoiding playing white screen for a long time, playing balanced pictures of various colors, and avoiding excessive attenuation of certain basic color LED lights; Equipped with brightness adjustment system, it can automatically adjust the brightness of LED display screen according to the ambient brightness, which can save power and avoid light pollution; Due to the light attenuation characteristics of LED, regular point-to-point correction can reduce the brightness of high LED lights to an average level, and effectively improve the uniformity of LED display screen.
.
results show that the LED display has the characteristics of light attenuation
