On the 16th, the national LED quality inspection center that Jining City fully prepared to build successfully passed the inspection of the General Administration of Quality Supervision, Inspection and Quarantine. At this point, Jining has the only national-level LED quality inspection center in the province. It is reported that the center can not only detect the light radiation intensity of electrical appliances, but even the texture composition of PM2.5 can be seen here.
"This darkroom is a photobiosafety inspection system. The lamps that need to be tested are placed here to detect the light radiation intensity of the lamps, the safety of the light radiation, etc." Wang Meixia, a technician at the National LED Inspection Center, said that as long as the LEDs are placed On the equipment entering the darkroom, according to its light irradiance and brightness, the damage caused by light radiation to the eyes and skin can be detected. The light radiation safety level of LEDs, energy-saving lamps, fluorescent lamps and other lamps can be measured.
In the reliability environment laboratory, several large-scale equipment can simulate the environment of temperature, illumination, etc., and put the product into it to detect the change of product performance when the environment changes suddenly. Scanning electron microscope analysis system, in addition to imaging the microscopic morphology of semiconductors, can also stereoscopically image smog and cashmere texture. Some materials that are invisible to the public can be seen here.
After on-site inspection of the laboratory and on-site inspection of the materials, the AQSIQ Acceptance Experts Group recognized the technical capabilities, team building and scientific research capabilities of the National Semiconductor and Display Products Supervision and Inspection Center. The center successfully passed the national quality inspection. The acceptance of the expert group of the General Administration has become the only national-level LED quality inspection center in Shandong Province.
“After acceptance, the center will better serve the development of the optoelectronic industry in Jining and surrounding provinces and cities.†Song Qingjun, director of the National Semiconductor and Display Products Supervision and Inspection Center, said that the center now has five optical darkrooms, such as photobiosafety testing and photometric calibration. . It has multiple test systems such as electromagnetic radiation and radiation resistance test system and EMC immunity test system. The scope of inspection covers electromagnetic compatibility and reliability environmental testing in the fields of semiconductor materials, lighting appliances and display products. At present, it has obtained the qualification of inspection power of 1,232 inspection projects, and the inspection capability basically covers LED industry substrates, epitaxial wafers, chips and devices. And industrial chains such as application products.
