subject: Led Products In Use Should Pay Attention To Several Problems [print this page] 1. Use LED products should pay attention to the anti-static
LED products in the production process of the processing to take anti-static measures, such as: workbench to be grounded, workers should wear anti-static clothing, take the anti-static ring, and with anti-static gloves etc. conditional can be installed antistatic ion fan, and at the same time, to ensure the production workshop humidity at about 65%, in order to avoid the air is too dry to produce static electricity, especially the green LED is easily damaged by static electricity. In addition, the quality of different grades of LED antistatic ability is different also, the quality and grade of high LED antistatic ability is stronger.
2. Use LED products should pay attention to use dc constant current power supply
Some manufacturers in order to reduce the cost of product use "resistance capacity decompression" way to LED products supply, and this will directly affect the service life of LED products. Should adopt special switch power supply (had better be constant current source) to the supply of LED products, so it won't affect service life of the product, despite the product cost relatively high.
3. Use LED products to pay attention to the temperature rise will make the LED internal resistance becomes smaller
When the outside ambient temperature rises, the LED light source internal resistance will be reduced, if use stabilized voltage power supply can cause LED working current rises, when over its the rated operating current, affect the service life of LED products, serious will LED light source "burn out", and therefore should choose constant current source power supply to ensure that the working current LED is not affected by the outside world temperature influence.
4. Use LED products should pay attention to LED product seal
LED products often use in outdoor, also face waterproof, moistureproof sealing problems, if processing is bad will directly influence the service life of LED products. Some on product quality requirements higher manufacturers adopt the traditional epoxy resin "casting" approach to seal LED products, this kind of method operation up more troublesome, for large LED products (such as LED guardrail lights) is not very suitable, it will cause the increase of the product weight.
5. Use LED products should pay attention to LED guardrail lights control technology
Currently, the LED guardrail lights the most widely applied control technology is "serial communication" mode. Its advantage is each fence light without specific "code", between each can be arbitrary exchange, facilitate the production and engineering installation. But its biggest drawback is that once had one damage, it will directly influence the followed by all fence light, for hundreds or even thousands of meters fence light engineering, because of the impact the external factors and the impact the product itself quality factors, it is difficult to guarantee each a guardrail lights don't appear problem, therefore, one fence light appear problem that namely caused part fence light paralysis.
