How to improve the life and brightness of the LED display?

Jun 22,2021| LED Knowledge

LED display screens have a wide range of applications in daily life, such as squares, stadiums, hotels, supermarkets, etc., as long as they can be seen in public places, you can see a large number of LED displays! How to make the life and brightness of LEDs reach The standard that satisfies all users is a very meaningful topic!

To maintain a long life and high brightness LED display, the problems to be solved are: power supply, LED light source, heat dissipation, and three key technologies. How to improve the life and brightness of the LED display?

1. Power

led power

The primary requirement of the power supply is high efficiency, high efficiency products, low heat generation, high stability will inevitably be high. Usually there are two options of isolation and non-isolation in the power supply part. The isolation volume is too large and the efficiency is low. There will be many problems in use and installation. The market prospects of non-isolation products are not as big as non-isolation products. Here we mainly discuss non-isolation Drive scheme.

2. LED light source

The chip is placed on the pin, and the heat energy passes through the silver pin to directly remove the heat generated by the chip node. It is qualitatively different from traditional in-line products and traditional SMD products in terms of heat dissipation. The node temperature of the chip will not be generated. Accumulation, thereby ensuring the good usability of the light source lamp beads, and ensuring the long life and low light attenuation of the light source lamp beads.

In traditional SMD products, although the positive and negative electrodes can be connected through the gold wire of the chip, it also allows the heat generated by the chip to be connected to the silver pin 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 lamp beads.

3. Heat dissipation

In consideration of heat dissipation, we separate the heat dissipation of the LED light source lamp beads and the heat dissipation of the power supply, and do not interfere with each other, so as to ensure 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 the heat dissipation through radiation is the focus of lamp beads.

LED display screens have a wide range of applications in daily life, such as squares, stadiums, hotels, supermarkets, etc., as long as they can be seen in public places, you can see a large number of LED displays! How to make the life and brightness of LEDs reach The standard that satisfies all users is a problem of considerable significance! To maintain a long life and high brightness LED display, the problems to be solved are: power supply, LED light source, heat dissipation, and three key technologies.
