Latest company news about How to judge whether the LED lamp caps are qualified

 

The quality of the LED lamp cap is not only related to the interests of our consumers, but also related to the personal safety of the users. Therefore, judging whether the quality of the LED lamp holder is problematic is important. Judging whether the quality is problematic, not only from the appearance ,but also be judged during use. Which can be screened from the following parts:

 

1. First of all, from the appearance, there should be no cracks, looseness, and traces of prying between the interfaces. During the installation and disassembly, the lamp cap should not be loose or tilted. The plastic shell of the lamp must be selected. Engineering plastics are flame-retardant, especially their surface has a texture similar to frosted glass, while ordinary plastics have a smooth and shiny surface, but are easily deformed and flammable. They are prohibited from being used in the production of energy-saving lamps.

 

2. The temperature of the LED lamp should be relatively low under the normal working state. If the heat dissipation condition is not good, the lamp bead will work at high temperature, the light decay will be large, and the lamp life will be greatly reduced. When it is on and off, if it flashes quickly, it also indicates that there is a quality problem.

 

3. To listen to the sound of work, we can simply judge through a small test. Bring a short- and medium-wave radio. When the lamp is working, put the radio nearby. The lower the noise received by the radio, the better the electromagnetic compatibility of the tested lamp. Listen to the sound of the LED lamp in a silent environment. If you can hear the sound of the lamp very clearly, it means that the power supply of the lamp is not very good.

 

4. Use a special lamp gauge for testing.
