The data detected by a single white LED lamp on the aging board is definitely different from the data detected when the white LED lamp is assembled into a lamp aging. The magnitude of this difference depends on the electrical parameters of the LED light source module when it is working, the design of the lamp, and the environment in which the lamp is used.

First of all, what kind of LED lamp beads to choose.

This is very important. The quality of LED lamp beads can be said to be a very important factor. To give some examples, the same is represented by Epistar 14mil white light segment chips, and the LED lamp beads are encapsulated with common epoxy resin primer, white light glue and packaging glue, and a single LED is lit in an environment of 30 degrees. After thousands of hours, the attenuation data is 70% light attenuation; if it is packaged with D-type low-attenuation glue, under the same aging environment, the thousand-hour light attenuation is 45%; if C-type low-attenuation glue is packaged, under the same aging environment , 1000-hour light decay is 12%; if type B low decay glue is encapsulated, under the same aging environment, 1000 hours light decay is -3%; if type A low decay glue, under the same aging environment, 1000 hours light Decay is -6%.
