Use LED products should pay attention to some problems

1. Anti-static

LED products in the process of production to anti-static measures, such as: workbench to grounding, workers must wear anti-static clothing, anti-static ring, and anti-static gloves, conditional can be installed anti-static ion blower, at the same time to ensure the production workshop humidity is around 65%, lest produce electrostatic air is too dry, especially the green leds easily damaged by static electricity. In addition, different quality of LED antistatic ability is different also, the quality of high quality LED some antistatic ability is better.

　　2. Should use dc constant current power supply

some manufacturers in order to reduce the product cost of the 'resistance capacity step-down' way to power a LED products, it will directly affect the service life of LED products. Should use the special switching power supply, It is best to constant current source) Power supply for LED product, so as not to affect the service life of the product, although the product cost is relatively high.

　　3. Temperature can make the LED resistance smaller

when the environment temperature, the LED light source internal resistance decreased, if use voltage regulator power supply will cause the LED working current increases, when more than the rated current, will affect the service life of LED products, serious will LED light source 'burn out', so the constant-current power supply should be chosen, to ensure the working current of the LED is not affected by ambient temperature.

　　4. LED products sealing

LED products are often used in outdoor, also faced with waterproof, moisture-proof seal problems, if processes is not good will directly affect the service life of LED products. Some manufacturers for product quality is higher by traditional 'watering' approach to epoxy resin sealing LED products, this kind of method to operate more troublesome, for large LED products ( Such as LED guardrail light) Is not very fit, it will result in an increase in product weight.

　　5. LED guardrail light control technology of

the current LED guardrail light is the most widely used control technology 'serial communication'. Its advantage is each fence light without specific 'code', can be arbitrary switching between each, facilitate production and engineering installation. But the biggest drawback is once there is a damage, will directly affect the following all guardrail lights, for hundreds or even thousands of meters fence light engineering, due to factors such as external factors and the quality of the product itself.
