How to improve the life and brightness of LED displays?

LED display in daily life has a wide range of applications, square, gymnasium, hotel, supermarket, and so on, but all can see the public places, can see the massive use of LED display! LED display to maintain a long life and high brightness, to solve the problem is: power supply, LED light source, heat dissipation, three key technologies. How to improve the life and brightness of LED displays?

1. Power supply
   The primary requirement of power supply is high efficiency, high efficiency products, heat generation is low, then the stability is necessarily high. Usually in the power supply part of the useful isolation and non-isolation of two programs, isolation of the volume is large, low efficiency, in use, installation aspects will produce many problems, not as large as the market prospects of non-isolated products, in this we mainly discuss non-isolated drive program.
2. LED light source
   The chip is placed on the pin, the heat will be directly over the silver foot chip node generated by the heat out, with the traditional direct plug products, and traditional SMD products in terms of heat dissipation is qualitatively different, the chip node temperature will not produce cumulative, thus ensuring the good use of the light source lamp beads, to ensure the long life of the light source lamp beads, low light decay. Traditional SMD products, although can be connected through the chip’s gold line positive and negative, but also so that the chip generated heat through the gold line connected to the silver foot, heat and electricity are conducted by money, the accumulation of heat over time will directly affect the life of the LED display lamp beads.
3. Heat dissipation
   In the heat dissipation consideration, we will LED light source lamp bead heat dissipation and power supply heat dissipation separately, do not interfere with each other, so as to ensure the reasonableness of heat dissipation. There are three ways of heat transfer: convection, conduction and radiation. In a closed environment, convection and conduction are less likely to be realised, while heat dissipation through radiation is a key consideration for the lamp beads.
   LED display in daily life has a wide range of applications, square, stadium, hotel, supermarket, and so on, but all can be seen in public places, can see the LED display a lot of use! LED display to maintain a long life and high brightness, to solve the problem is: power supply, LED light source, heat dissipation, the three key technologies.
