How to solve the cooling problem of indoor LED display?led aluminum cabinet screen distributors

　　1. Extensibility: The larger the indoor LED display, the higher the investment of the production line equipment. The increase in the size of the LED display is easy, just like building blocks. The resolution is also convenient to achieve according to user needs.

　　2. Full color: Light bulbs, neon lights, etc. are all monochrome. LED implements a combination of RGB three primary colors.

　　3. High reliability: LED is solid lighting, high reliability, unlike neon lamps, light bulbs, etc. The vacuum tube is required.

　　4. Long life: LED chip theoretical life span can reach 100,000 hours, and the actual service life is more than 30,000 hours.

　　5. Environmental friendly: The LED display itself is an energy -saving and pollution -free product.

　　So where does the heat come from? From power supply to LED lights, to LED drivers, to adjustable resistors, the heating part includes LED lights, LED drivers, and LED connectors. We take 5V power supply as an example:

　　Power voltage: 5V.

　　LED: LED G/B VFWD = 3.2V, LED R VFWD = 2V

　　1. LED luminous efficiency is about 20%, LED heating accounts for 50%of the total heat

　　2. The controller and connection line account for about 5% of total heat

　　3. Driving voltage drop: 1.8V (g/b) or 3V (R) voltage drop, the driving part of the heating accounts for 45%of the total heat.
