The Necessity Of Applying For Ul Certification For Led Lamps

    With the advancement of technology and the enhancement of people's awareness of environmental protection, LEDs with energy-saving functions have basically entered most people's homes. The LED light is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wires, and is sealed with epoxy resin around it to protect the inner core wire. Finally, the housing is installed, so the shock resistance of the LED light is good. However, my country's LED lighting products generally need to apply for UL certification to export to the United States. In addition, the US Federal Regulations "Electrical Works Law" also clearly requires related products to pass UL certification. Those UL indoor and outdoor light sets have passed the test program and are eligible for export abroad.

    The UL certification test project for LED lamps includes performance tests in these areas:

    1. Input test;

    2. Lamp gauge test;

    3. Lamp head torque test;

    4. Lamp head tensile test;

    5. Drop test;

    6. Dimming test;

    7. Stress relief test;

    8. Temperature rise test;

    9. Abnormal short circuit test of components;

    10. LVLE output test;

    11. Rain test (if the bulb is used in a place exposed to rain, it needs to be done);

    12. Tide test;

    13. Withstand voltage test;

    14. Leakage current test;

    15. Durability test (if the lens and the shell are fixed by glue instead of mechanical fixation, a durability test of about half a month is required; or directly fixed with special UL-certified glue.
