Led large screen long working hours secret
Dec 17, 2018

  Because of LED, IC are semiconductor devices, they are critical of the use of environmental requirements, best at room temperature 25 ℃ or so, its working mechanism is the best.But in fact a large outdoor LED screen can be applied at different temperatures,Degree of environment, may be in more than 60 ℃ in summer, winter may be under - 20 ℃.When the LED large screen manufacturer production product is 25 ℃ as test conditions, the different step of product classification, the truth conditions for operation60 ℃ and 20 ℃, LED, IC work efficiency and performance, may belong to a becomes more original file, the brightness is not consistent, screen, but natural spent.This is because of the different temperature bars Pieces, red, green, blue three kinds of the brightness of the light attenuation and drop is different, at 25 ℃, the white balance is normal, but at 60 ℃, 3 kinds of color of the LED brightness are decreased, and the attenuation values are not consistent,Therefore, the brightness of the whole screen will drop and the color will be biased, and the quality of the whole screen will decline.The IC?Working temperature range is in IC - 40 ℃ to 85 ℃.The temperature inside the box will rise due to the high external temperature, if the box Temperature over 85 ℃, IC, because temperature is too high, cause of the work is not stable, or the channel between current extraction and temperature drift or caused by too much difference between flowers screen.

  Therefore, star glory technology believes that fast heat dissipation is the key to the led large screen to work for a long time and ensure its life expectancy.Star glory r & d production of pre-maintenance aluminum module is a new heat dissipation artifact, super heat dissipation capacity, high temperature resistance, radiation resistance, oxidation resistance.Effectively ensure the normal operation of led large screen
