          CLEAR plans LED spotlight test results released nearly 90% product identification confusion

          [High-tech LED reporter / Yin Mingquan] In order to let LED lighting manufacturers (including dealers, engineering buyers, individual consumers) identify the true state of the product, in the past three months, Gaogong LED in the country 30 The provincial capital city and lighting concentrated exhibition area purchased a number of brands of LED lighting sources and lighting products, including LED bulbs, LED downlights, LED straight tube lights, LED spotlights, LED panel lights, etc., and commissioned third parties. The testing organization conducted actual performance tests on the above products.

          Recently, the fourth round of voluntary test results of the CLEAR project, which was participated in the investigation and testing of China's LED testing and certification industry, was released. The LED spotlights tested in this round were 23 models from 23 brands.

          The fourth round of CLEAR Voluntary Test Project continues to be tested according to the requirements of the LM79-80 standard. The test project covers total luminous flux, luminous efficacy, correlated color temperature, color rendering index, total harmonic distortion, power factor, etc., and the test results are combined with US energy. The requirements of the Stars were compared.

          The nominal power of the selected samples is 3W and 4W. The test data of 11 spotlight samples are compared with the requirements of ENERGY STAR. The minimum total luminous flux and power factor are not satisfactory, and 17 samples meet the minimum light efficiency requirements. The compliance rate was 74%. Two samples met the requirements of the color rendering index, the compliance rate was 9%, and the relevant color temperature was 9 to meet the requirements, and the compliance rate was 39%. No product meets the overall requirements of DLC for the product.

          Analyze samples according to ENERGY STAR standards:


          According to the relevant test items, the sample test results are statistically shown in the following figure (where the red dotted line is the limit):










          In addition, nearly 90% of the spotlights tested in this test, the company did not indicate the luminous flux and color rendering index in the product and the outer packaging box.

          Among them, the brands with no nominal luminous flux, luminous efficacy, color temperature and color rendering index are Yaweiguang, Haoying Lighting, Highlights, Leo, Letia, Hongguang and Langxing. There are three brands with no nominal luminous flux, luminous efficacy and color rendering index: Op Lighting, Snowlight, Foshan Lighting, Thunder, Dragon, Golden Jazz, Lake, Teyou Shi, Wrigley, Huayi Lighting.

          In the comparison between single measurement and nominal parameters, the nominal luminous flux of Orkney's THD-301W model spotlight is 300 lumens, the measured data is only 217.2 lumens, and the virtual gain flux indicator is 27.6%.

          For the situation that the actual test results of the LED spotlights are different from the product nominal data and the identification parameters of the product packaging are confusing, Gaogong LED has recently visited the industry and interpreted the test results.

          "Marking W is a problem with conversion rate. 5W multiplied by 7 is 35W, 7W multiplied by 7 is 49W. You may have this view, so mark W. Normally, we should have 100lm/w for one light. However, many companies may have enough wattage to cut corners, but the actual light efficiency is only 60 or 50.a€? Peng Chengxue, deputy general manager of Hubei Gontong Electronics Co., Ltd., a member of G20-LED, said that many companies should not cooperate with the market price. Do not do some "spoofing" the market. If the industry can regulate, there is a corresponding reference value, and if you come back to make products, it will reduce a lot of "intangible damage" that affects the word-of-light of LED lights.

          The person in charge of a certain LED company in Ningbo also said that this phenomenon is unique to the Chinese mainland market and is quite different from the export products. "The LED products we export are clearly identified, such as power, lumens, color temperature, color rendering index, power factor, light exit angle, power supply isolation, service life, etc." For the domestic phenomenon of "tapping taiji" in the outer packaging, it is largely because there is no standard and no standard in the drilling market. If the parameters are identified on the outer packaging of the product, then the company is responsible for these markings.

          According to the person in charge of the CLEAR program, the next high-tech LED will also cooperate with industry experts and experts to dismantle the spotlights tested above, and evaluate the products from materials, key components, power supplies, etc. Test data for analysis and interpretation.
