Construction of semiconductor lighting detection system to promote industrial development

Semiconductor lighting technology to enhance its application scope is expanding, the impact on people's daily lives are increasing. Therefore the establishment of semiconductor lighting detection and evaluation platform of public authority, justice, the formation of semiconductor lighting detection system, network, test and evaluation of the company's products, product quality testing is very necessary to provide convincing data. In addition, LED is not only a semiconductor device, but also a new type of light source, so it is difficult to measure the electrical parameters, optical parameters, thermal parameters and so on. Although China's lighting products producing countries, but domestic enterprises are small, the breakthrough in semiconductor lighting products production, the majority of enterprises is difficult to independently detect semiconductor lighting products in the enterprise, so the detection in the public inspection and evaluation platform, research methods and instrument testing at the same time, it is very critical the.

In this case, many city and regions have set up local inspection agencies, as the development of semiconductor lighting industry an important part to support, just a few years the rapid emergence of a number of semiconductor lighting detection mechanism. However, at present, these have been built, in the construction of the testing agency staffing, site equipment in the end how? Whether you have the actual testing ability? Test methods and standards have been unified? Whether the test results are consistent with the results of routine comparison National testing agencies have formed a network pattern?

In view of the above problems, this print in the near future on the domestic semiconductor lighting inspection institutions were investigated. According to the results of our investigation found that the current domestic semiconductor lighting testing development level is uneven, the overall detection system is still relatively confused, unified testing standards and testing methods are not, have not formed the network, providing testing services authority so that it is difficult to timely and effectively to the government, consumers and enterprises, even in the test results a detection mechanism of different products are not the same, the user does not know which products should be selected according to the results of the detection mechanism, causing confusion in the market, seriously affected the rapid development of semiconductor lighting industry, for the long-term development of China's semiconductor lighting industry with the world and very bad. Therefore, it is necessary for us to build a unified and perfect product testing system for the healthy development of China's semiconductor lighting.

Investigation of China semiconductor lighting products testing organization

In this paper, the recent domestic semiconductor lighting inspection institutions conducted a survey, collected a total of 21 key cities, more than 25 of the size of the information. Based on the comparison and analysis of the detection ability, asset size, funding sources, operating mechanism and geographical distribution of the testing institutions.

Detection ability

Because the semiconductor lighting products more and more into people's daily life, whether in government procurement, project bidding, or people's daily purchase, are required for certification testing and evaluation of semiconductor lighting products, so the demand is very great. However, due to the quality of testing agencies around the staff quality, testing equipment are different, so the detection ability of different institutions are also very different. According to the detection ability of the division, the current domestic testing institutions can be broadly divided into the following four categories: first, there is a certain basis for the work of the national testing center. These countries have a long time to build the testing agency, has carried out a large number of semiconductor lighting products testing, semiconductor lighting products in the detection of a wealth of experience and staffing. The two is to build a new semiconductor lighting specifically for testing institutions. This kind of detection are mostly in recent years due to the national and local invest a lot of money to set up down, mostly with good hardware conditions, but the personnel technical level and detection ability needs to be further strengthened. Third kinds of detection mechanism is based on the original traditional lighting detection mechanism, a new semiconductor lighting product testing project, this kind of mechanism has some traditional detection based lighting products, but in the construction of testing equipment and the ability of semiconductor lighting products is insufficient. The fourth category is based on the enterprise or research laboratory testing platform. These testing platform is generally located in the laboratories of enterprises and institutions, has a certain product testing capabilities, but in terms of size and personnel affected by the support unit, the development of instability.

Asset scale

Due to the importance of the local government attaches importance to the testing agencies, the original basis of the testing institutions are different, so the current development of different testing agencies is also different. This has reflected testing equipment in testing institutions, working conditions, such as detection of platform condition is perfect, detection equipment configuration has reached advanced international and domestic leading level, whether the basic coverage of the semiconductor lighting industry chain and application products required for testing projects, whether on LED devices, LED source LED, lamps and other kinds of semiconductor lighting products, including the photometric characteristics and color properties, electrical properties, thermal properties, aging properties, reliability, security and other characteristics of radiation detection analysis and evaluation, whether can achieve the lighting on the road and tunnel lighting, indoor and outdoor lighting, decorative lighting, automotive lighting, landscape industrial lighting and construction industry
