Today, LCF will tell you about a series of damages caused by long-term overheating of the LED display. When you see these damages, you may pay more attention to the daily maintenance.

LED display heating temperature is too high will cause wavelength drift: do you know? This can cause color correction to fail, and the wavelength shift of the LED is relatively large at low and high temperatures.


The high heating temperature of the LED display will cause the output brightness to decrease: according to our understanding, every degree Celsius temperature change causes a 1% change in the output brightness. It is worth mentioning that the red light is the most affected, and its brightness will be reduced by nearly two-thirds. Relatively speaking, the brightness of blue and green lights is not so strongly affected by temperature. When the temperature rises, the brightness emitted by LEDs of different colors is not the same.


The high heating temperature of the LED display will shorten the life of the LED: according to the data of a laboratory in a certain country, the junction temperature increased from 63C to 74C, and the LED life was reduced from 36,000 hours to 16,000 hours.


The high heating temperature of the LED display will increase the system cost: too many heat dissipation components are damaged, and once they are broken, they must be reconfigured, which increases the system cost.


The high heating temperature of the LED display will increase the cost of use: due to the excessive consumption of energy, the cost of use will increase.
