National Quality Supervision and Inspection Center for semiconductor devices

Ensure water cube landscape lighting project

In September 2007, the National Center for quality supervision and testing of semiconductor devices was officially recognized as the Olympic venues - National Swimming Center (Water Cube) landscape lighting engineering system testing and quality assurance unit. In order to ensure the LED landscape lighting project quality, led by the National Semiconductor Devices Quality Supervision and inspection center, the national construction engineering quality supervision and inspection center, the national quality supervision and inspection center of electronic instruments, the national electric light source quality supervision and Inspection Center (Beijing) Consortium LED landscape lighting National Swimming Center inspection and the Ministry of information industry product quality relay connector supervision and inspection center is composed of members of the unit, in accordance with a successful quality control of military products, the key point of LED industry chain preventing idea of National Swimming Center building LED landscape lighting project on the process of strict and effective control of the whole process of quality inspection and testing from various aspects of the chip, package the lamp, lens, control system, power supply, connectors, LED, display and so on, to ensure that the selection in China Quality of the equipment in the home swimming centre.

Specific as follows: Division of semiconductor devices by the State Quality Supervision and inspection center as a consortium led by Party, responsible for organization and management, screen LED, LED light, light source module and integrated circuit (IC), discrete devices (two, semiconductor triode) and control system components test. National electric light source quality supervision and Inspection Center (Beijing) and the national construction engineering quality supervision and inspection center is responsible for the testing of lamps. Ministry of information industry connector relay product quality supervision and inspection center is responsible for connector, connector test. The national electronic equipment quality supervision and inspection center is responsible for the testing of AC/DC power supply, wire and cable, low voltage distribution cabinet. The national construction engineering quality supervision and inspection center is responsible for the testing of lens materials, LED display and landscape lighting.

In July 8, 2008, Beijing city "2008" Project Management Office of the organization, through the technical and economic experts to review, expert conclusions as "the project in the implementation process, the LED components of the whole, the whole process of supervision, ensure the landscape lighting project has reached a high level, and distinctive high quality. This project studies the LED testing technology and the evaluation method of landscape lighting, and develops a set of corresponding acceptance rules, which provides the basis for the acceptance test of the related projects in the future. "Through the success of the Olympic Games show that the" Water Cube "is a major bright spot, the national semiconductor device quality supervision and inspection center is also proud of this.

Purchase equipment to a higher level

SPECTR0320 equipment: in order to meet the needs of high power LED lighting and semiconductor device testing, national quality supervision and inspection center has purchased the German INSTRUMENT company SYSTEMS SPECTR0320 equipment for more accurate and authoritative test on LED (has signed a purchase agreement is expected in December 2008, arrival) measurable parameters include: LED light, luminous flux, radiation flux brightness, light intensity angular distribution, spectral power distribution, dominant wavelength, color purity, color rendering index, color temperature etc..

A large scale distributed photometric measurement system for measuring the spatial light intensity distribution and various photometric parameters of indoor and outdoor lighting fixtures. Including: the spatial intensity distribution curve, arbitrary cross section luminous intensity distribution curve, illumination distribution curve, brightness limit curve, area efficiency, luminous flux, lighting glare grade, lamps for total luminous flux, luminous flux, some utilization coefficient, and electrical parameters (power, power factor, voltage and current) etc..

LED aging test system: the purchase of LED aging test system is expected to arrive in October 2008.

Domestic leading test items

High power LED thermal resistance parameter testing: National Semiconductor device quality supervision and testing center with domestic (NC2992) and imported (TESEC9634-KT) a total of two sets of testing systems, and has accumulated rich experience in testing.

LED accelerated life test: National Semiconductor Devices Quality Supervision and inspection center completed the preliminary research work to develop "industry standard LED accelerated life test method", will be the first "best linear unbiased estimation method for white LED color temperature drift of the accelerated life test; in the domestic first put forward the effectiveness criterion of white LED color temperature drift. The recently proposed" LED accelerated life test method "industry standard framework has been recognized by industry authorities.
