After assembling the finished product in the production of LED lamps, in principle, an aging test is required.
The main purpose is to see whether the light decay of the LED lamp is actually damaged during the assembly process.

LED lighting principle: The PN junction in the LED is driven by a voltage, and the internal electrons and holes will recombine, and the energy in the recombination process will be released in the form of light, that is, the working principle of th...
After night falls, the electric light will help us solve the lighting problem.
Electric lights are essential appliances in the home.
The lamps sold on the market are mainly divided into LED lamps and incandescent lamps.
Is it correct that led ligh...
Iam know The development of LED lamps has gone through five stages
One: In the 1960s and people learned the basics of semiconductor materials.
that can produce light and the first commercial LED diodes were produced in 1960.
Two: The core part of ...
LED lights It is a semiconductor diode with a long service life. When the luminous flux drops to 80%, its service life reaches 50,000 hours.
The service life of metal halide lamps is 6000~12000 hours, and the service life of high pressure sodium...
