Research on continuous measurement system for luminescence properties of LED sources

A continue measurement system for luminescence properties of LED sources has been researched and developed, by multi-using various testing devices of LEDs, based on removable guideway, multi-testing locations, computer control and Lab VIEW software. The comprehensive luminescence properties, including electrical, photometric and colorimetric characteristics, could be automatically and continuously measured, when the LED source moved through three different testing locations, which were named as intensity testing location, integrating sphere testing location and spatial distribution testing location in turn. This measurement system and method have displayed some remarkable merits, such as synthesis, automatic, integration, continuity and on-line. The study would help to improve the measurement level of LEDs, and increase the dependability and veracity of testing results.
