Zhenjiang Inspection and Quarantine Bureau National Lighting Laboratory develops a new luminous flux tester. Under the support of Jiangsu Inspection and Quarantine Bureau's project "Development of LED Photometric Performance Evaluation and Luminous Flux Tester under Intermediate Vision Condition" and "Research on LED Light Effect Characteristics", the Luminaire Laboratory united Jiangsu University of Science and Technology and Hangzhou Chuanghui Instrument Equipment Co., Ltd. , Developed a new light flux meter. The instrument not only can measure the visual chromaticity parameters like the general instrument, but also can accurately measure the intermediate vision, dark vision, the visual light flux of the division and the pupil luminous flux. The instrument plays an important role in the performance of the light source, especially the detection of the LED performance.
