The LED display heating temperature is too high and damage instructions:
1. Wavelength drift: do you know? This will cause the color correction to fail, and the wavelength drift of the LED is relatively large at low and high temperatures.
2. Reduced output brightness: According to our knowledge, every degree Celsius temperature change results in a 1% change in 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 the blue light and the green LED Light module have less temperature influence. When the temperature rises, the brightness of LEDs of different colors is different.
3. Leading to shortened LED life: 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.
4. Increased system cost: Too many heat-dissipating components are damaged and must be reconfigured once broken, which increases the system cost.
5. Increase the cost of use: Because of the excessive consumption of energy, the cost of use will increase.
