How to increase the service life of led outdoor displays?

1. Switching power supply

The main requirement of switching power supply is high efficiency, and the reliability of high-efficiency products is inevitably high if it is hot. Usually in the power supply part of the effective protection and non-protection of the two schemes, the isolation volume is slightly larger, the high efficiency is relatively low, in the process of use, there will be many problems at the assembly level, compared with the industry prospects of non-protective new products, here we focus on the non-isolation to promote the plan scheme.

 

2. LED light source

The processing chip is placed on the pin, and the heat passes through the silver foot to directly remove the subtropical zone formed by the connection point of the processing chip, which is qualitatively different from the traditional direct insertion goods and the traditional SMD goods at the heat exhaust level, and the ambient temperature of the chip connection point will not cause accumulation, which fully guarantees the excellent applicability of the light source lamp beads and ensures the long life and low light loss of the light source lamp beads. Traditional SMD products, although the positive and negative can be connected through the chip line, and at the same time, the heat generated by the processing chip is connected to the silver foot through the line, and the heat and electrical energy are transmitted by money, and the heat accumulation time will be directly related to the service life of LED outdoor display LED lamp beads.

 

3. Heat dissipation

In the consideration of heat dissipation, we separate the heat conductivity of the LED light source LED lamp beads and the heat dissipation of the power supply, and do not interfere with each other, so as to fully ensure the rationalization of heat dissipation. There are three paths for heat conduction, heat convection, transfer, and radiation sources. In a closed environment, the heat convection and transmission are likely to be relatively small, and the heat is released through the radiation source, which is the core consideration of LED lamp beads.

 

LED outdoor display is widely used in daily life, city squares, stadiums, hotels, restaurants, shopping malls, these, as long as it is visible in public places, you can see the wide use of LED outdoor display! How to make the LED service life and chromaticity to make the application satisfactory specifications, is a very practical problem! LED outdoor display has always maintained a long life and high brightness, to solve the problem is: switching power supply, LED light source, heat exhaust, three core technologies.

 

LED outdoor display daily maintenance concept:

 

With the continuous improvement of LED technology in recent years, the performance and protective equipment of LED outdoor LED screens have been greatly improved, and many customers have also neglected to remove and maintain.

 

In fact, after long-term use of LED outdoor LED screen, a large amount of dust and residue will be deposited on the surface, it is very important to remove and maintain on time, in addition, it should be noted that whether it is independent or ask full-time personnel to remove maintenance, it is necessary to ensure that the switching power supply is broken under the premise of carrying out.

 

To create a regular inspection mechanism for the display screen, the inspection content is mainly based on the existence of the LED outdoor display itself whether there is abnormal sound, abnormal taste and abnormal color shift to ensure that the maintenance frequency once a week is ensured. If it cannot be used for a long time, it is necessary to conduct a safety inspection in advance.

 

When the monitor plays video, it prevents the interface from being all green, pure white and purple red, etc., due to the long-term full brightness of the interface, it is easy to cause current overload and hot switching power supply, which has serious harm to the service life of the display.
