LED lighting products have broad market prospects, especially in the lighting field. Currently used in the field of LED lighting lighting products are more, such as LED guardrail light, LED lawn lamp, LED spotlights, LED underwater lights, LED buried lights. Although we have a better understanding of energy-saving LED light source has a long life, no radiation (green light), etc., but with several key issues related to LED products also need attention. :

First, the use of DC constant current power supply

LED products to be used for switching power supply (constant current source) to power this 様 LED products will not affect the life of the product, but the product cost is relatively high. So some manufacturers to reduce product costs using RC Buck way to power LED product, which will directly affect the life 様 LED products.

Second, to make anti-static measures

Different levels of quality LED products, in terms of ability are not the same anti-static, so LED products in the processing and production process to the use of certain anti-static measures, such as: table grounding, wear anti-static clothing, with anti-static ring with anti-static gloves, anti-static conditions can be installed fan, but also to ensure humidity around 65%, in order to avoid the air too dry to generate static electricity, especially the green LED, it is relatively easier to be damaged by static electricity.

Third, the temperature will result smaller LED resistance

When the ambient temperature rises, LED light source will reduce the resistance, the choice of constant current power supply, to ensure that LED current is not affected by the outside temperature.

Four, LED products seal

Application of outdoor LED products, are faced with a waterproof, moisture-proof sealing problems, if not handled properly it will directly affect the life of LED products. Traditional epoxy resin "watering" approach to seal LED products, this method of operating is too much trouble, causes an increase in weight of the product.

The quality of the current LED products on the market and the poor, good quality high brightness LED light source, light is small, strong anti-static capacity, long life, but the price is several times more expensive than the cheapest. While some LED lighting project with a low quality LED light source, then I do not find any problems, but will soon be "missing incomplete" and therefore manufacturers and users not in the price "flame." Selection of affordable, good quality LED light source, to ensure the life of lighting engineering.
