Five points to pay attention to in the life of LED lamp beads
The service life of LED lamp beads is a mutual concern between companies and customers. For a good product, its life span must be within the corresponding valid range, which can meet everyone's using needs. Therefore, when designing and conceiving LED lighting products, designers must not only ensure the performance of LED products but also ensure the service life of LED lights which requires adjustment of some main parameters during design. This article will explain the basic parameters of LED and the relevant knowledge of LED lamps' life span.
Generally, the temperature of current components of semiconductor materials affects the service life of components. Many electronic tubes with high power in electronic equipment are fixed on the high-efficiency heat sink. The service life of LED lamp beads also mainly depends on temperature. The service life of lamp beads is usually It can be expressed as lamp failure (no light) and light loss (reduced light intensity).
The key factor that endangers the service life of LED lamp beads is light loss. The light loss is expressed by the light intensity maintenance rate. Generally, during the warranty period, the light loss cannot be less than 30% of the initial light intensity. The basic parameters related to the service life of the lamp beads are:
Environment and operating temperature, under the same heat rejection standard, the higher the environment and temperature, the shorter the lamp bead service life.
The smaller the driving current, the longer the life of the lamp beads.
The better the quality of the packaging material, the longer the service life of the lamp beads.
The higher the working efficiency of the heat exhaust structure, the longer the service life of the lamp beads.
The higher the electrostatic protection level of the chip and package, the longer the life of the lamp beads.
The service life of LED lamp beads is closely related to the above factors. If you want to fully extend the service life of the lamp beads, you need to pay attention to the changes in this factor all the time. In general, in order to prolong the service life of LED lamp beads, it is necessary to avoid high-temperature environments and choose products with smaller driving currents. In addition, the packaging material is also the most critical part, which can ensure the protection level of static electricity, thereby ensuring the service life of the lamp beads.
