The hot summer is approaching. The maximum outdoor temperature in most parts of the country can reach above 40°C. The operating temperature of LED displays without a cooling system may be as high as 70°C or above, which is undoubtedly for the service life and operation stability of the product. It's a huge test. How to cool down your LED display from the root?

We know that electronic products have a commonality. Taking mobile phones as an example, when the operating temperature becomes higher and it feels obviously hot, the power consumption will increase, and problems such as jamming or even automatic shutdown will occur. The LED display is no exception. When the temperature is high, the probability of problems will increase, and the stability and service life of the product will also be affected.

Most users mainly take measures such as adding exhaust fans and air conditioners to reduce the temperature of the screen, but this also further increases power consumption to a certain extent. So, why don't we reduce the temperature of the LED display from the source?

According to the law of energy conservation, if all the energy of the LED display cannot be used to emit light, the excess energy can only be consumed by heating, which will increase the temperature of the screen. With the development of technology, the normal operation of the LED display only needs to use 4.5V/4V switching power supply. If 5V switching power supply is used, the excess electric energy will only be converted into heat energy and consumed, which will cause waste and increase the screen body. temperature.

Topsun's indoor and outdoor products are the first to use 4.5V/4V switching power supply, which can not only save power consumption, but also effectively reduce the operating temperature of the LED display. The experimental data shows that the temperature of products using 4.5V is about 10% lower than that of products using 5V; the temperature of products using 4V is about 20% lower than that of products using 5V. Assuming that the screen temperature is 70°C, the temperature can be reduced to about 56°C with a 4V switching power supply.

   Not only that, there are many benefits of using 4.5V/4V switching power supply

1. The brightness of products using 4.5V/4V power supply is basically the same as that of products using 5V power supply

2. Using 4.5V/4V power supply is the same as using 5V product with load

3. Using a 4.5V power supply will save more than 10% of the power of a single product than using a 5V power supply;

Using a 4V power supply can save more than 20% of the power of a single product than using a 5V power supply;

4. 4V power supply with Tuosheng Optoelectronics DS-PWM driver IC, the comprehensive energy saving is 30%

5. 4V power supply with Tuosheng Optoelectronics PWM-SS driver IC, comprehensive energy saving 35%-50%

The 5V switching power supply consumes energy and increases the temperature of the screen, which affects the stability and service life of the product. It should be eliminated. Tuosheng Optoelectronics actively responds to the national call for energy conservation and emission reduction. In order to provide users with better products, it strongly advocates the use of 4.5 V/4V switching power supply, I hope the whole industry will work with us to promote the popularization of 4.5V/4V switching power supply.
