1.DC LED drive power should be used for led tube driver: Some manufacturers use "resistance-capacitance step-down" to power LED products in order to reduce product costs, which will directly affect the life of LED products. Using a dedicated switching power supply (preferably a constant current source) to led tube driver r to the LED product will not affect the service life of the product, but the product cost is relatively high.
2.The temperature of the LED: It should be noted that the increase in temperature will reduce the internal resistance of the LED. When the external environment temperature rises, the internal resistance of the LED light source will decrease. Exceeding its rated operating current will affect the service life of the LED product, and will cause the LED light source to "burn out" in serious cases. Therefore, it is best to use a constant current source for power supply to ensure that the LED operating current is not affected by external temperature. LED temperature is also the most important factor affecting LED life. Please pay attention to it.
3.Sealing of LED products: No matter what LED products are used outdoors, they are faced with sealing problems of waterproof and moisture-proof. If they are not handled well, they will directly affect the service life of LED products. At present, a small number of manufacturers with relatively high product quality requirements use the traditional epoxy resin "pouring" method to seal LED products. This method is more troublesome to operate and is not very suitable for larger LED products. Cause the weight of the product to increase.
