LED display has a wide range of applications in daily life, squares, stadiums, hotels, supermarkets, etc., but in public places that can be seen, you can see the extensive use of LED display! How to make the LED life and brightness reach The standard that satisfies the use is a question of considerable significance! The LED display should maintain long life and high brightness. The problems to be solved are: power supply, LED light source, heat dissipation, and three key technologies. How to improve the LED display life and brightness?
Power supply
The primary requirement of the power supply is high efficiency and high efficiency. If the heat is low, the stability will be high. Generally, there are two schemes of isolation and non-isolation in the power supply part. The isolation volume is large and the efficiency is low. In use, there are many problems in installation. It is not as good as the market prospect of non-isolated products. Here we mainly discuss non-isolation. Drive solution.
2.LED light source
The chip is placed on the pin, and the thermal energy passes through the silver foot directly to the tropical part generated by the chip node. Compared with the traditional in-line product and the traditional patch product, the thermal temperature is different, and the node temperature of the chip does not generate. Accumulation, thus ensuring the good use of the light source bead, ensuring the long life of the light source bead, low light decay. Although the traditional patch products can be connected to the positive and negative electrodes through the gold wire of the chip, and the thermal energy generated by the chip is connected to the silver foot through the gold wire, the conduction of heat and electricity is conducted by money, and the heat accumulation time is long. Will directly affect the life of the LED display bead.
3. Heat dissipation
In the heat dissipation consideration, we separate the heat dissipation of the LED light source bead and the heat dissipation of the power supply, and do not interfere with each other, thereby ensuring the rationality of heat dissipation. There are three ways of heat conduction, convection, conduction and radiation. In a closed environment, convection and conduction are less likely to be achieved, and heat is emitted by radiation, which is the focus of the lamp bead.
