    COMPONENT RELIABILITY VERIFICATION

    The components designed during the development process must undergo rigorous reliability tests, such as high and low temperature alternating test, high temperature and high humidity test, temperature test, etc. The company is equipped with perfect test tools to protect the reliability of product design.

    • High and low temperature alternating current tester

      The high and low temperature alternating current tester can simulate various temperature and humidity environments, and is suitable for detecting electronic, electrical appliances, rubber, plastic glue, metal and other products, and meets the reliability stability performance of GB/T2423, GJB150A1/4 in various harsh environments. Parameters provide the basis for preventing and improving product quality and reliability.

    • High temperature and high humidity tester

      It is used for reliability test in high temperature and high humidity environment. For the parts and materials of the product in the case of high temperature and high humidity environment, check its performance indicators.

    • Withstand temperature tester

      It is used to test the material structure or composite material, and it can withstand the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time in the short-term continuous environment under extremely high temperature and very low temperature.



    • PRODUCT PLAN VERIFICATION

      After the assembled parts are assembled using the qualified parts, the optical, thermal and electrical aspects of the overall solution are verified to ensure that the products meet the design standards and safety standards.

    • Photometric integrating sphere

      It can be used for measuring the photoelectric parameters of indoor LED lamps, including luminous flux, luminous efficiency and color temperature, power, power factor, power, current and voltage.

    • LED lighting photometer (IES test)

      It is used for the spatial light intensity distribution of LED lamps and the determination of various photometric parameters, including spatial light intensity distribution curve, light intensity distribution curve on any section, equal illumination distribution curve, brightness limit curve, regional luminous flux, lamp efficiency, glare Grade, total luminous flux of the luminaire, effective luminous flux, utilization factor; and electrical parameters (power, power factor, voltage, current).

    • Withstand voltage tester

      The withstand voltage tester is an instrument for measuring the withstand voltage strength. It can intuitively, accurately, quickly and reliably test the withstand voltage, breakdown voltage, leakage current and other electrical safety performance indicators, and can be used in IEC or Under different test conditions specified by national safety standards, different forms of dielectric properties such as power frequency and direct current and current shock wave are tested. It can eliminate the damage to the insulation caused by raw materials, processing or transportation, and reduce the early failure rate of the product.

    • EMC tester

      It can be used for measuring the photoelectric parameters of indoor LED lamps, including luminous flux, luminous efficiency and color temperature, power, power factor, power, current and voltage.

    • Leakage current tester

      Leakage current tester is used to test the current flowing through the insulated part of an electrical circuit or device without failure or voltage application. As one of the important indicators to measure the insulation performance of electrical appliances, leakage current is the main indicator of product safety performance, which plays an important role in improving product safety performance.



    • TRIAL PRODUCTION

      After the sample is confirmed to be qualified, the batch materials are put into consideration to confirm the feasibility and convenience of assembly, and the product quality consistency is analyzed and determined during this period.

    • Accelerated aging test system

      Based on the Arrhenius model, the life at other temperatures is extrapolated by the results obtained from the accelerated life of high temperatures.
