How to improve LED display life and brightness?

LED display has a wide range of applications in daily life, square, gymnasium, hotel, supermarket, etc., as long as you can see the public places, you can see a large number of LED display use! How to make the service life and brightness of led meet the standard of satisfaction, is a very meaningful topic! LED display to maintain long life and high brightness, to solve the problem is: power supply, LED light source, heat dissipation, three key technologies. How to improve LED display life and brightness?

1. Power Supply

The primary requirement of power supply is high efficiency, high efficiency products, low heating stability is bound to be high. Usually in the power supply part useful isolation and non-isolation of two solutions, isolation volume is too large, low efficiency, in use, installation will produce a lot of problems, as the non-isolation of the product market prospects, here we mainly discuss the non-isolation of the driving scheme.

2.LED light source

The chip is placed on the pin, and the heat energy is directly generated by the chip node out through the silver pin, which is different from the traditional direct-insert products and traditional patch products in terms of heat dissipation. The temperature of the chip node will not accumulate, so as to ensure the good usability of the light source lamp beads, long life and low light decay. Although traditional patch products can connect the positive and negative electrodes through the gold wire of the chip, they also allow the heat generated by the chip to connect to the silver foot through the gold wire. The conduction of heat and electricity is conducted by money, and the accumulation of heat for a long time will directly affect the life of LED display beads.

Step 3 Dissipate heat

In the heat dissipation consideration, we will separate the heat dissipation of LED light beads and the heat dissipation of power supply, do not interfere with each other, so as to ensure the rationality of heat dissipation. There are three ways of conducting heat, convection, conduction and radiation. In a closed environment, convection and conduction are less likely to be realized, and heat emission through radiation is the key consideration of the lamp bead.
