The summer heat is approaching. The maximum outdoor temperature in most parts of the country can reach above 40 °C. The temperature of the LED display without the cooling system can be as high as 70 °C, which is undoubtedly the service life and operational stability of the product. It is a huge test. How to cool your LED display from the root cause?
We know that electronic products have a commonality. Take mobile phones as an example. When the operating temperature becomes high, the feeling is obviously hot, the power consumption will be faster, and there will be problems such as card machine and even automatic shutdown. The LED display is no exception. When the temperature is high, the probability of occurrence of problems will increase, and the stability and service life of the product will also be affected.
Most users lower the temperature of the screen body by adopting measures such as adding an exhaust fan and adding air conditioning, but this also further increases the power consumption to some extent. So why don't we reduce the temperature of the LED display from the source?
According to the law of conservation of energy, if all the energy of the LED display cannot be used for illumination, the excess energy can only be consumed by the heat, which will increase the temperature of the screen. With the development of technology, LED display screens can only be operated with 4.5V/4V switching power supply. If 5V switching power supply is used, the excess power will only be converted into heat energy, which will waste and increase the screen. temperature.
Tuosheng Optoelectronics indoor and outdoor products take the lead in using 4.5V/4V switching power supply, which not only saves power consumption, but also effectively reduces the operating temperature of LED display. The experimental data shows that the temperature of the product using 4.5V is about 10% lower than that of the product using 5V; the temperature of the product using 4V is about 20% lower than that of the product using 5V. Assuming the screen temperature is 70 ° C, using a 4V switching power supply, the temperature can be reduced to about 56 ° C.
Not only that, but the benefits of using a 4.5V/4V switching power supply are many.
1. The brightness of the product using the 4.5V/4V power supply and the 5V power supply is basically the same.
2. Use a 4.5V/4V power supply and use the 5V product to load the same
3. Using a 4.5V power supply will save more than 10% of the power of a single product compared to using a 5V power supply;
Using a 4V power supply can save more than 20% of power in a single product compared to using a 5V power supply;
4. 4V power supply with Tuosheng photoelectric DS-PWM driver IC, comprehensive energy saving 30%
5. 4V power supply with Tuosheng photoelectric PWM-SS driver IC, comprehensive energy saving 35%-50%
5V switching power supply consumes energy and increases screen temperature, which affects product stability and service life. It should be eliminated. Tuosheng Optoelectronics actively responds to the national energy conservation and emission reduction call, and also provides users with better products. V/4V switching power supply, I hope the whole industry and us together to promote the popularization of 4.5V/4V switching power supply.
