LED lamp bead manufacturers introduce the long life of LED l
LED lamp bead manufacturers introduce the long life of LED lamp beads? Many engineers who develop new products, when looking for LED lamp bead models and selecting them, will consult and understand, 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, are the packaging method of led lamp bead, the life of LED lamp bead is long, in fact, the relationship with packaging is not very Big.
The life of the LED lamp bead is mainly related to the packaging material of the LED lamp bead and the operating temperature of the LED lamp bead, which are the key to determining the life of the LED lamp bead.
LED lamp life calculation
The life of the LED lamp bead is calculated based on the length of time that the brightness of the lamp bead is reduced to less than 50%.
Basically, the US and Japan imported lamp chip can be used for about 70,000 hours, and the total damage time is more than 10w hours;
The lamp life of Taiwanese companies can be used for about 50,000 to 60,000 hours;
Domestically produced lamp beads are more difficult to say. Regular enterprises can produce more than 50,000 hours. The industry is fiercely competitive. Some Led packaging manufacturers blindly pursue low prices, choose small chips, or poor material packaging, the same conditions of use. The life expectancy may be only a few thousand to 20,000 hours.
In addition, it depends on what products the buyer mainly uses. It is used on the instructions, and the life will be longer. When used on lighting fixtures, the life will be shorter. Because the use time of the LED lamp will include the service life of the LED lamp bead and the service life of the driving power supply, one of the accessories is broken, which will also affect the life of the LED lamp bead.
