GL Optic Introduces TEC Control System at LpS 2015

GL Optic, which has its headquarters in Weilheim/Teck, Germany, has introduced a new complete temperature regulation and control solution for LED measurements. The GL TEC Control System includes a spectrometer, integrating sphere, programmable power supply and sophisticated software in a well-harmonized set. The GL TEC Control System is used in development labs for test and development of new LED drivers, LED chips and lights.

Light measurements on LED lighting now extend beyond the realm of conventional optical measurements to include the effects of electrical and thermal operating variables on the optical parameters of LEDs. This raises the bar for lighting manufacturers and developers who in the past have relied on simple applications using integrating spheres. New industry standards require reliable, stable conditions for surface temperatures and power supplies. This in turn creates the need to regulate and stabilize the temperature of high-power LEDs during the measurements or to simulate various LED operating temperatures. New test standards such as CIE S 025/E:2015 force lighting manufacturers and developers to place greater emphasis on heat control.

This has created an incentive for GL Optic to develop a complete heat regulation solution. The GL TEC Control System includes the lab-grade GL SPECTIS 6.0 spectrometer and TEC Mount with Peltier element for cooling or heating connected to a cutting-edge TEC controller which performs the control functions and displays the temperature. Both in turn are connected to a GL OPTI SPHERE 500 integrating sphere and a programmable power supply. Based on high-precision temperature monitoring and control, the module creates stable measurement conditions and can simulate nearly any operating temperature. Heat control is managed by GL AUTOMATION, a powerful tool which is part of the GL SPECTROSOFT software package. It is used to operate all of the attached instrumentation or to plan, conduct and monitor automated test scenarios.

If you are looking for reliable, high-precision spectrometers and controllable light measurement systems with intuitive operation, the cutting-edge GL TEC Control systems are your best option. They meet all of your spectral light measurement needs. GL Optic supplies complete SOLUTIONS for measuring illuminance [lx], luminous flux [lm], CRI, CCT, color, luminance [cd/m²] and much more.
