White Paper: FluxGage - A Photometric Test System for LED Luminaires Based on Solar Panels
White Paper: FluxGage - A Photometric Test System for LED Luminaires Based on Solar Panels We present a novel photometric test system for LED luminaires. The new photometric system called „FluxGage“ uses solar panels to detect and measure light. By placing a diffuser and a black pinhole array over a solar panels we achieve a detection surface which is also an absorber. This enables the system to be the same size as the DUT (Device Under Test), as opposed to an integrating sphere which is at least 3 times larger than the DUT. Simulations and experimental results show that this system can measure total flux with an uncertainty of 4.3%. The demonstrated system is used in 2π geometry. The system measures total flux, color parameters (CCT, CRI, chromaticity, etc.) and flicker. Read more »

Obtaining the Highest Candle Beam Power for Spotlights
Obtaining the Highest Candle Beam Power for Spotlights Sponsor Philips Lumileds --- Lumen density in the LED source is very significant in final design. Obtaining Center Beam Candle Power is a goal in high quality applications including retail and architectural lighting. High Power LEDs are the perfect solution to creating high lumen intensity from a very small light emitting source. Creating a very high lumen per mm square enables the highest center beam candle power in a system. Where other COB's need ~35-35mm for high lumen packages, LUXEON S5000 can achieve 8000 lumens in a Light Emitting Surface of just 17mm. Creating great spotlights has never been easier. Read more »
