North Sutton, New Hampshire – Labsphere, Inc. has signed a cooperation agreement with National Lighting Test Centre (Shanghai). The partnership, facilitated by Labsphere distributor, Shanghai Alpha Lighting Equipment Testing Ltd., is centered on Labsphere’s TOCS LED Measurement System.

The National Lighting Test Centre’s National Luminaries Quality Supervision Testing Centre is the first professional international laboratory for lighting equipment in China. Under this agreement, Labsphere supplied the center with its Thermal/Optical/Electrical LED Measurement Systems (TOCS), to which the center will apply its patent (Measurement Devices for LED Forward Voltage Drop and Junction Temperature Curve, Patent No.: ZL2009 2 0212653.0) to correlate voltage drop with junction temperature. Additionally, the companies have agreed to actively share information pertaining to developing lighting trends and to cooperate in the launch of academic communications and activities.

The Labsphere LED TOCS enables measurement of optical properties as a function of temperature and operating current using a single instrument, complying with international standards and regulations. TOCS adheres to the IESNA (Illuminating Engineering Society of North America) LM-79 standard to produce accurate and repeatable LED measurement results. TOCS systems are based on integrating sphere technology and can be used for 2pi and 4pi measurements. The basic TOCS system consists of an integrating sphere (50cm to 300cm in size), high resolution CCD spectrometer, light source, power supply and proprietary Labsphere TOCS software.

Labsphere, a Halma company, is a world leading designer and manufacturer of precision radiometric and photometric test and measurement products addressing the specific needs of the aerospace, electronic imaging, LED, lighting, medical imaging and optics industries. The company offers a broad line of integrating sphere systems, uniform calibration sources, spectroscopy accessories and diffuse reflectance materials and coatings.
