The biggest problem currently encountered by indoor LED displays is heat dissipation, and the same is true for LED displays. Indoor led display screens consume a lot of power, and a considerable part of the energy is wasted on heat. Fever can cause many problems. Why can led display screens be widely used, and how to solve the heat dissipation problem of indoor led display screens? The editor's summary is the following:
1. Scalability: The bigger the indoor led display screen is, the higher the equipment investment in the production line. The increase in the size of the led display is very easy, just like building blocks. The resolution is also convenient to realize according to user needs.
2. Full color: light bulbs, neon lights, etc. are all monochromatic, and LED realizes the combination of RGB three primary colors. How to solve the heat dissipation problem of indoor led display?
3. High reliability: LED is solid-state lighting with high reliability, unlike neon tubes, bulbs and the like that require vacuum tubes.
4. Long life: The theoretical life of the LED chip can reach 100,000 hours, and the actual life is more than 30,000 hours.
5. Environmentally friendly: LED display itself is an energy-saving and pollution-free product.
So where does the heat come from? From the power supply to the LED lamp, to the LED driver, and then to the adjustable resistor, the heating part includes the LED lamp, the LED driver, and the LED connection line. Let's take 5V power supply as an example:
Power supply voltage: 5V.
1. The LED luminous efficiency is about 20%, and the LED heating accounts for 50% of the total heating
2. The controller and connecting wires account for about 5% of the total heat generation
3. Drive voltage drop: 1.8V(G/B) or 3V(R) voltage drop, the heating of the drive part accounts for more than 45% of the total heating.
The heating of the indoor LED display LED lamp needs to improve the luminous efficiency of the LED, and the controller and the connecting line have less heating, and there is not much room for improvement. There is a lot of room for improvement in the heat generation of the driving part, and it is also the part we look forward to improving.
