What is the lifespan of the smd LED chip?
LED lamp beads manufacturers introduce how long is the life of LED lamp beads? Many engineers who develop new products will consult and understand when looking for LED lamp bead models and selecting them, how long is the life of LED lamp beads?
Whether it is in-line Led lamp bead, SMD type Led lamp bead, high-power LED lamp bead, cob lamp bead, it is the packaging method of LED lamp bead, and the life of LED lamp bead is not very related to the packaging method. big.
The life of the LED lamp bead is mainly related to the packaging material of the LED lamp bead and the use temperature of the LED lamp bead, which are the keys to determine the life of the LED lamp bead.
Life Calculation of LED Lamp Beads
The lifespan of the LED lamp bead is calculated based on the use time when the brightness of the lamp bead is reduced to less than 50%.
Basically, the LED chip imported from the United States and Japan can be used for about 70,000 hours, and the total damage time is more than 10w hours;
The lamp beads packaged by Taiwanese companies can be used for about 50,000 to 60,000 hours;
It is more difficult to say the lamp beads produced in China. The production of regular enterprises can reach more than 50,000 hours. The competition in the industry is fierce. Some LED packaging manufacturers blindly pursue low prices and choose small chips or poor material packaging. The same conditions of use The lifespan may be only a few thousand to 20,000 hours.
In addition, it also depends on what products the buyer mainly uses. For instructions, the lifespan will be longer, and for lighting fixtures, the lifespan will be shorter. Because the use time of LED lamps includes the service life of LED lamp beads and the service life of driving power supply, one of the accessories is broken, which will also affect the life of LED lamp beads.
