TOCS LED Measurement Systems

Labsphere Inc offers new Thermal/Optical/Electrical LED Measurement Systems (TOCS) that conform to LM-79 and LM-80 with single instrument. To more easily meet new reporting specifications, these systems enable measurement of optical properties as a function of temperature and operating current using a single instrument. The TOCS complies with IESNA LM-79 standards, delivering accurate and reproducible LED measurements. Available in a range of integrating sphere sizes from 50 cm to 193 cm, the TOCS systems are designed for both 2 pi and 4 pi measurement geometries. A lamp measurement integrating sphere, high resolution CCD array spectrometer, thermal plate with temperature controller, auxiliary lamp, calibration source, power supply and Labsphere’s powerful TOCS-SS software comprise the basic system. Owners of current Labsphere and SphereOptics spectral lamp measurement systems may purchase an upgrade retrofit to the TOCS system to achieve LM-79 compliance. TOCS-SS is powerful, accurate software, which automates procedures for measuring spectral characteristics, and controlling current and temperature. Users control LED temperature and operating current at specified ranges, measuring and characterising the device under test over a wide temperature range. The simultaneously collected electrical, optical and thermal data is graphed for quick on-screen viewing and can be exported to Excel format for in-depth analysis. The TOCS can be customised with the integrating sphere size, calibration source and accessories to fit testing needs. The company, a subsidiary of Halma p.l.c., is world leader in light testing and measurement and optical coatings. Products include LED, laser and traditional light source light measurement systems; uniform light sources for imaging device calibration; spectroscopy accessories; and high diffuse reflectance materials and coatings for applications in backlit panel displays, computed radiography, and system calibration.
