Led test instruments supplier in China

LED lighting products are rapidly replacing traditional lighting products due to their superior luminous performance and high efficiency and energy saving. With people’s continuous pursuit of high efficiency and health, LED lighting products and technologies are constantly improving. The important basis for this is how to effectively and accurately measure LED actual performance, for which LED testing equipment is an important part. LED lighting covers optical, electromagnetic and environmental/mechanical disciplines, and its technical content and complexity far exceed that of general electronic products. At present, there are no more than 10 companies involved in the world. As one of the best LED test equipment manufacturers in China, LISUN can provide comprehensive testing solutions for LED lighting products. Our 4 core products are as follows:

1. Photometry & Colorimetric measurement(including LPCE-2/LPCE-3 Spectroradiometer & Integrating Sphere System, LSG-6000/LSG-1800A Distributed Photometer, LRF-3 SVM, Pst LM Strobe Tester, LM-80/ LM-84 LED aging life test equipment and EN62471 optical radiation safety test system, etc.). Among them, the most basic and common is the LPCE-2/LPCE-3 spectroradiometer & integrating sphere system. Compared with other manufacturers, LISUN integrating sphere is manufactured by one-time stamping die (the interior of the sphere is smoother and the reflection effect is better). ) Secondly, our sphere contains an up/down direction + height adjustable stage (which can test all types of LED lights/lamps and tube products), and there is a cross laser device inside the sphere to calibrate the standard lamp/tested lamp Install it so that it is always in the center of the ball; other manufacturers are still using welding technology (that is, welded from several pieces of iron) and there is only one light pole inside the ball.

2. EMC-electromagnetic compatibility test (including EMI-electromagnetic interference test such as EMI-9KB and EMS-electromagnetic anti-susceptibility test such as ESD61000-2 electrostatic discharge test, EFT61000-4 pulse group test, SG61000-5 lightning surge test, RFCI61000- 6 RF conduction test, PFM61000-8A power frequency magnetic field test, CSS61000-11 voltage cycle drop test and RWG61000-12 ring wave test, etc.

3. Safety test class (including electrical safety testers such as LS9923/LS9955 withstand voltage/insulation/grounding/leakage current test, material heat resistance/fire resistance test such as ZRS-3H glow wire equipment, ZY-3 needle flame combustion equipment and HVR-LS Horizontal and vertical burners, etc., as well as physical/mechanical safety tests such as SMT-1 standard test finger, ZBP-T ball pressure device, GNG lamp holder/lamp holder gauge, etc.

4. Environmental test(Including GDJS series high and low temperature & humidity test chamber, JL-X/SC-015 IP waterproof/dustproof test, JL-9K1L IPX9 high temperature/high pressure waterproof test chamber, IK07-10 IK impact protection test, LVD -100KG-6D vibration test, UV-263LS UV aging test box and XD-80LS xenon lamp aging test box, etc.). Among them, the most common tests are the high and low temperature & humidity test chamber (environmental durability test) and IP waterproof/dustproof test. LISUN has developed GDJS series environmental test chambers based on years of experience in the lighting industry (features: even the tested lamps are fully Under the load state, the test temperature in the box can still fully meet the specification requirements. Secondly, the electronic humidity sensor imported from Finland is used. Even if the test runs for a long time, there is no need for separate maintenance. However, many domestic environmental test box manufacturers have product standard specifications and actual test time The specifications are different (because the objects under test are generally non-heating products, that is, the objects under test do not generate heat when they work, but LED lighting products will generate a lot of heat when they work, especially in a closed environment, which is why they test the environment box specifications The problem is -40°C~150°C, and the actual test temperature is only -20°C or higher when the low temperature is -40°C. Secondly, many domestic manufacturers purchase wet and dry bulbs to measure humidity to reduce costs, but dry and wet bulbs need Frequent maintenance and replacement, if maintenance is not timely, it is easy to have problems and cannot do humidity test. LISUN has written a separate article on the analysis of China’s domestic high and low temperature & humidity test chamber market, please refer to: https://www.lisungroup for details .com/news/technology-news/high-low-temperature-humidity-test-chamber-analysis-in-china-market.html
