Led Street Light Housing Manufacturers Introduces The Prevention Details Of Led Aging
Led lamps are already very common in life, so after a long time of use, there will be many problems. Today, Led Street Light Housing Manufacturers will introduce the factors of LED aging:
1. There are problems with the soldering process when applying the product, such as too high soldering temperature, too long soldering time, and failure to do anti-static work. More than 95% of these problems are caused by the packaging process.
2. The quality of the LED product itself or the production process.
3. LED aging methods to include constant current aging and constant voltage aging.Constant current source means that the current is constant at any time. If there is a frequency problem, it is not a constant current. That is alternating current or pulsating current. AC or pulsating current source can be designed to have a constant effective value, but this kind of power source cannot be called a constant current source.Constant current aging is the most scientific LED aging method in line with the working characteristics of LED current. Overcurrent impact aging is also the latest aging method adopted by manufacturers. This type of aging is carried out by using a constant current source with adjustable frequency and adjustable current. , In order to judge the quality and life expectancy of the LED in a short time, and can pick out many hidden LEDs that cannot be picked out by conventional aging.
4. Aging is an important guarantee for the reliability of electronic products and is the last essential step in product production. LED products can improve performance after aging and contribute to stable performance in later use. The LED aging test is a very important link in product quality control, but in many cases, it is often overlooked and cannot be properly and effectively aging.The LED aging test is a countermeasure taken according to the characteristics of the product’s failure rate curve, that is, the bathtub curve, to improve the reliability of the product, but this method is not necessary. After all, the aging test sacrifices the life of a single LED product. At the cost.
