LED products in the processing and production process should take anti-static measures, such as: table to the ground, workers wear anti-static clothing, anti-static belt loop, as well as with anti-static gloves, conditions can install anti-static ion fan, while ensuring workshop humidity around 65%, so the air is too dry to produce static electricity, especially the green LED easily damaged by static. In addition, different quality grades of LED antistatic ability is not the same, the quality of high grade LED antistatic ability is stronger.
In order to reduce product cost, Some manufacturers use “RC Buck” approach to power LED products, this will directly affect the life of LED products. Should be used for switching power supply (preferably a constant current source) to power LED products, so it will not affect the service life of the product.
When the ambient temperature rises, LED light resistance will be reduced, if the use of a regulated power supply will cause the LED current increases, when more than its rated operating current, it will affect the life of LED products will be serious LED light source, “burn” and therefore should be used in constant current power supply to ensure that LED current is not affected by the outside temperature.
LED products are often used in outdoor, also facing waterproof, moisture-proof sealing problems if not properly handled will directly affect the life of LED products. Some products require a relatively high quality traditional epoxy manufacturer “watering” approach to sealing LED products, this method operate more trouble, for the larger volume of LED products (such as LED guardrail lamps) is not very suitable , will cause an increase in product weight.
LED guardrail lamps before the most widely used control technology is “Serial Communications” approach. The advantage is that each guardrail lamps no specific “code”, can be arbitrarily between each exchange, to facilitate the production and installation works. But its biggest drawback is that if there is a damage, it will directly affect all the lights behind it, for hundreds or even thousands of meters of fence light engineering, due to the impact of external factors and the quality of the product itself and other factors, it is difficult to ensure that every a guardrail lights are not a problem, so a fence light problems that paralyzed part of the guardrail lamps.
