Whether it is in-line Led lamp beads, SMD Led lamp beads, high-power LED lamp beads, and cob lamp beads, all are the packaging methods of LED lamp beads. The life span of LED lamp beads is not very much related to the packaging method. Big.
The life of LED lamp beads is mainly related to the packaging material of the LED lamp beads and the use temperature of the LED lamp beads. These two are the key to determining the life of the LED lamp beads.
Life calculation of LED lamp beads
The lifespan of LED lamp beads is calculated based on the use time when the brightness of the lamp beads is reduced below 50%.
Basically speaking, the lamp bead chips imported from the United States and Japan can be used for about 70,000 hours, and the time for all damage is more than 10w hours;
The life of the lamp beads packaged by 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 and choose small chips or poorer materials for packaging. The same conditions of use The life span may be only a few thousand to twenty thousand hours.
In addition, it also depends on what product the buyer mainly uses. It will have a longer life when used for instructions, and will have a shorter life when used in lighting fixtures. Because the use time of the LED lamp will include the service life of the LED lamp beads and the service life of the driving power supply, one of the accessories is broken, and it will also affect the life of the LED lamp beads.
