          The third batch of voluntary test results of China's CLEAR project announced

          [Source: Gaogong LED 's " LED Lighting Channel" magazine January issue ]

          Recently, the third round of voluntary testing of China's CLEAR project, which was jointly conducted by China LED testing and certification industry leader and the media partner Gaogong LED, has been officially announced. The LED products of this round are related to bulbs and tubes. There are 47 products of lamps, spotlights and straight tube lamps, including 11 bulbs, 14 downlights, 6 spotlights and 13 straight tube lamps.

          The third 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. Product data in the database of Stars, DLC, and lightingfacts are compared and analyzed. From the test data results, this round of test data has made significant progress compared with the second round of test data of CLEAR in China. It can be seen that after development, the manufacturing R&D capability of Chinese LED manufacturers has steadily increased. Some indicators of this round of testing are close to or even exceed the average level of sample products in the US market, but the overall indicators of individual products are not optimistic. This is a common problem of most LED manufacturers, excessive pursuit of high light efficiency, and neglected the color rendering index. Other optical performance parameters such as correlated color temperature and lumen maintenance, ignoring the balance of LEDs as lighting products should focus on performance parameters.

          Taking the bulb as an example, the test data of 11 bulb samples compared with the requirements of ENERGY STAR, all samples are in line with the ENERGY STAR efficacy, the compliance rate is 100%, and the 7 samples meet the color rendering index. Requirements, the compliance rate reached 64%, and the relevant color temperature reached 9 requirements, with a compliance rate of 82%.

          Analysis of bulbs according to ENERGY STAR requirements:




          According to the standard requirements of DLC, the test data of 13 samples of the sampled lamps showed that there were 12 models that met the requirements of light efficiency and R9, the compliance rate was about 92%, and 11 of them met the requirements of the color rendering index, and the compliance rate was 85%. The related color temperature and power factor are 7 products, and the compliance rate is 54%. However, only one product meets the overall requirements of DLC for the product.

          Analysis of LED tubes according to DLC requirements:




          Encouragingly, when some test data are compared with CALiPER and other authoritative data in the United States, the total luminous flux, color rendering index, and light efficiency data are better than those published by relevant US agencies, and the correlated color temperature is close to or better than the US market. The data.

          (Commercially Available LED Product Evaluation and Reporting) is a US Department of Energy (DOE) commercialized and feasible LED product evaluation and reporting project. CALiPER obtains first-hand information and data through sampling inspection of LED products in the market, so that consumers can truly understand the characteristics of products and provide evidence for research and development of research institutions and large enterprises. The CALiPER testing program has played a pivotal role in the rapid development of the US solid-state lighting industry.

          In order to regulate the orderly competition of China's LED market, promote the healthy and sustainable development of China's LED industry, and enhance consumers' confidence in LED products, the company has introduced China's CLEAR (China LED Evaluation) with the practice and experience of CALiPER. And Assessment Report) project. "This is an independent and fair public welfare inspection project, and it is also the social responsibility of our company. We hope to promote China's LED fair competition by publishing objective, scientific and accurate test data, and formulate and adjust LED industry policies for the country. It provides reference for standard setting and, more importantly, can provide reference for Chinese consumers.a€? Mr. Nie Pengxiang, President of Incentive Testing, said.
