What will happen to the LED screen after running at high temperature for too long?


Some clients ignore the heat dissipation of the screen itself when some clients purchase a outdoor LED screens. SightLED team has 10 years of experience in the production and field use of LED screens. Now we will share What will happen to the LED screen after running at high temperature for too long.


1. Excessive temperature may cause the LEDs dead

 If the operating temperature of the LED display exceeds the load temperature of the chip, the luminous efficiency of the LED display will be rapidly reduced, resulting in obvious brightness decay, which will cause damage to the LED lamp.


2. Excessive temperature may shorten the life span of the led display

 High temperature is one of the main reasons that cause LED display brightness decay and shorten the life of LED display. The speed of light attenuation determines the life of the led display. Too fast light attenuation will cause the brightness to decrease rapidly until it is finally “dead”.

3. The increase in temperature will reduce the luminous efficiency of the led display

 

4. Excessive temperature will affect the luminous wavelength and display color of the led display


To sum up, only when the working temperature of the LED screen is in the right conditions can the life of the LED display screen be not shortened, the light efficiency is not reduced, and the color is not distorted. Then how to effectively prevent the LED from overheating? Based on years of accumulated experience, SightLED is very clear about effective methods and will be shared in the next article.
