What is the reason that affects the service life of LED lamps?

There are four main factors that affect the life of LED lamps. The quality of (1) die is the first condition to determine the life of LED: in the manufacturing process of LED, the pollution of other impurity ions, lattice defects and other technological processes will affect its life, so the use of high-quality LED die is the first condition. (2) Whether the post-process packaging is reasonable will affect the life of LED: Whether the post-process packaging of LED is reasonable will affect the life of LED. At present, several major companies in the world, such as Cree, Lumilends, Riya and other high-end LED packages have patent protection. These companies have high requirements for post-process packaging, and the LED life is guaranteed. However, in most enterprises, there are many imitations of LED post-packaging, which have acceptable appearance, but their technological structure and quality are poor, thus seriously affecting the life of LED. (3) The design of lamps is a key issue that affects the life of LED lamps: besides meeting other indicators of lamps, a key issue of reasonable lamp design is to radiate the heat energy generated when the LED is lit. The original high-quality LED products of Cree and other companies are used in different lamps, and the LED life can be several times or even dozens of times different. For example, the integrated light source lamps (single 30W, 50W, 100W) sold in the market have poor heat dissipation at the contact part between the light source and the heat dissipation channel, which leads to the light attenuation of some products by more than 50% after lighting 1-3 months, and the light attenuation of some products is very fast after using a small power tube of about 0.07W These products have low technical content, low cost and short service life. (4) The power supply of lamps is very important to the life of LED: whether lamps use electricity reasonably will also affect their life. Because LED is a current-driven device, if the power supply current fluctuates greatly or the pulse frequency of the power supply tip is high, the life of LED light source will be affected. The life of the power supply itself mainly depends on whether the power supply design is reasonable. On the premise of reasonable power supply design, the life of power supply depends on the life of components.
