LED detection equipment demand increased to reach the industry leading level

With the continuous improvement of the performance of LED, the application of LED has been widened, which has been developed from indication and display to lighting. In recent years, the application of landscape lighting, display, special lighting and LCD backlight is the challenge and opportunity for LED testing equipment. LED is a kind of semiconductor junction light-emitting products, the products of light, electricity, heat, life, and the traditional tungsten thermal radiation source, gas discharge light source, there is a big difference. At present, there are still many problems to be solved in the practical application, especially the application of high-power white LED lighting in the inspection, whether it is LED new product development, quality control of the production process or the end product, testing equipment is an important tool to promote the development of semiconductor lighting industry.

Internationally, LED testing equipment mainly from the United States, Germany and Japan and other countries. In recent years, the development of China's LED testing equipment is also very fast, has been involved in the LED chips, light-emitting materials, LED devices, LED lamps and lamps and other sectors. In the packaging and application, China's industrial group is large, on detection equipment demand is large, especially in recent years, high-power white LED gradually entered the field of lighting, the product is still in the primary stage, the product color consistency, reliability, thermal management is not satisfactory in ten, LED products online testing and sorting equipment, thermal performance testing instrument, life and reliability of test equipment is the bottleneck of industrial development.

Product safety testing of domestic equipment to meet the basic needs

Safety testing equipment including electrical safety, material fire safety and LED optical radiation safety and other safety detection equipment. Electrical safety and fire safety materials such as conventional safety testing equipment similar to the traditional electrical products, there are a variety of domestic equipment. At present, domestic equipment can basically meet the needs of the domestic industry.

It is worth mentioning that the LED optical radiation safety testing equipment. In recent years, the power and the external quantum efficiency of LED chips have been greatly improved, and high power blue LED chips have been widely used in the field of general lighting. With the development of high power multi chip integration and the two optical technology, the security of LED optical radiation has been paid more and more attention. EU countries have LED products into the mandatory safety certification CE radiation safety indicators.

At present, our country is in the forefront of the world in the LED optical radiation safety detection. In the light of the International Commission on illumination, CIE, and the International Electrotechnical Commission (IEC), China has played a major role in the LED optical radiation safety measurement. According to Hangzhou Zheda trichrome Instrument Co Ltd based on photoelectric detection and biological safety for many years, according to LED radiation safety testing has developed domestic equipment with independent intellectual property rights of success, and as a test between the Chinese members currently consists of 5 countries of the international LED optical radiation safety. Held in the Hungarian capital Budapest at the beginning of the June CIE interim meeting, a new proposal "in China's Zhejiang tricolor Photobiological Safety measure" lighting products to obtain the formal national representatives voted, and optical radiation safety measurement of LED products is one of the main contents.

Application of product performance testing equipment to achieve localization

LED applications for optical and optoelectronic detection equipment, has basically achieved localization. At present, in the LED industry applications, such as light intensity, luminous flux, color, electrical performance and so on more than 90% of the detection equipment is made of domestic testing equipment. The performance of some instruments have reached the international advanced level, testing equipment such as LED light distribution, energy efficiency and color performance, LED LED display and backlight, not only can fully meet the needs of the domestic industry, and there is a part of the detection equipment exported to foreign markets, including PHILIPS lighting laboratory, the National Institute of standards and Institute of technology, NIST and other international high-end laboratory.

The degree of automation of production line testing equipment needs to be improved

At present, the LED chip in the manufacture of photoelectric performance consistency is still relatively poor, mainly rely on the chip automatic sorting equipment for detection. With the in-depth application of LED in the field of display and lighting, the precision of LED chips is higher. Chip automatic sorting machine is one of the most important equipment in the LED industry.

In the production of white LED devices, the LED chip, the existing discrete coating process, resulting in the photochromic properties of discrete LED device is larger, in order to achieve consistency in the performance of the end product, must be packaged LED device sub file. At present, the high-end LED device color separation machine still need to import. In recent years, with the development of LED packaging industry, there are a number of domestic development of domestic equipment, basically able to meet the needs of the domestic market.

LED module, array and application of automatic online testing, the lack of the corresponding automation equipment. Part of the domestic unit has begun the development of semi-automatic equipment, with the application of product standards and market norms, domestic equipment will have further development.

The environmental performance test equipment is widely used

The environmental performance test equipment which can be applied to LED products can also be used in electrical products. This kind of equipment has strong versatility and wide application, and there are many manufacturers in our country. Therefore, the test equipment of LED, such as dust, rain, salt fog and so on, has been made in china. Environmental performance test set
