How to solve the heat dissipation problem of indoor high-definition display?
The biggest problem that indoor high-definition displays currently encounter is heat dissipation. Indoor high-definition displays consume a lot of power, and a considerable part of the energy is wasted on heating. Fever can cause many problems. So how to solve the heat dissipation problem of indoor high-definition display? Indoor high-definition display manufacturer - New Screen Optoelectronics summarizes the following points:
1. Scalability: The larger the indoor high-definition display, the higher the investment in production line equipment. The increase in the size of the indoor high-definition display is very easy, just like building blocks. Resolution is also easy to achieve according to user needs.
2. Full color: light bulbs, neon lights, etc. are all monochrome, and LED realizes the combination of RGB three primary colors.
3. High reliability: LED is solid lighting with high reliability, unlike neon tubes, light bulbs and the like that require vacuum tubes.
4. Long lifespan: The theoretical lifespan of LED chips can reach 100,000 hours, and the actual lifespan 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 of the indoor high-definition display come from? From power supply to LED lights, to LED drivers, to adjustable resistors, the heating part includes LED lights, LED drivers, and LED cables. Let's take 5V power supply as an example:
1. The LED luminous efficiency is about 20%, and the LED heat accounts for 50% of the total heat
2. The controller and connecting wires account for about 5% of the total calorific value
3. Driving voltage drop: 1.8V (G/B) or 3V (R) voltage drop, the heating of the driving part accounts for more than 45% of the total heating.
The heat generation of indoor high-definition display LED lights needs to improve the luminous efficiency of LED. There is a lot of room for improvement in the heat generation of the driving part, which is also the part we expect to improve.
