In the era of LED display flooding, maybe you don't know how to start with LED products. Beijing Jianhong Weiye advertising company lists the problems that can't be ignored for LED display products. 1. DC constant current power supply should be used for power supply. In order to reduce the cost of products, some manufacturers use the method of "resistance capacitance voltage reduction" to supply power to LED products, This will directly affect the life of LED products.
using a special switching power supply (preferably a current source) to power LED products will not affect the service life of the products.
but the cost of the products is relatively high.

2. Anti static measures should be taken during the processing and production of LED products.
for example, the workbench should be grounded, workers should wear anti-static clothing and anti-static ring, The anti-static ion fan can be installed if conditions permit. At the same time, the humidity of the workshop should be kept at about 65% to prevent the air from being too dry to generate static electricity, especially the green LED is relatively easy to be damaged by static electricity.
in addition.
the anti-static ability of LED of different quality grades is also different, The anti-static ability of high-quality LED is better.
3. It should be noted that the increase of temperature will reduce the internal resistance of LED, and the internal resistance of LED light source will decrease when the ambient temperature rises.
if the regulated power supply is used for power supply, the working current of LED will increase. When the rated working current exceeds, the service life of LED products will be affected, and the LED light source will "burn out" seriously, Therefore, it is better to choose constant current source to ensure that the working current of LED is not affected by the external temperature.
4. No matter what led products are, the sealing of LED products is faced with the problem of waterproof and moisture-proof as long as they are applied outdoors, If it is not handled properly, it will directly affect the service life of LED products.
at present, a small number of manufacturers with relatively high requirements for product quality use the traditional epoxy resin "pouring" method to seal LED products.
in recent years, the quality of LED products has been greatly improvedThis method is troublesome to operate, and it is not suitable for large LED products (such as LED guardrail lamp), which will also increase the weight of the products.
in addition.
at present, the quality of LED light sources on the market varies greatly. A good quantity of LED light sources not only has high brightness, small light decay and strong antistatic ability, but also determines their long service life, But its price is several times higher than that of cheap LED light source.
we will often see some LED lighting projects.
it's really beautiful, but it will soon be "incomplete", Some projects can't even be completed yet.
therefore, manufacturers and users should not "fight" over the price.
choose high-quality LED light sources.
take effective technical measures to ensure the quality of LED products is the way out.
