Fudan University jointly crack Philips LED Glare

　　In recent years, with the rapid development of LED light sources in road lighting applications, LED lights for discomfort glare problems caused by the driver and pedestrian attracted more and more attention. In many areas, street lights at night to reduce the brightness of the drivers repeatedly suffer from night vision caused by a sudden change, reducing the driving safety benefits provided by street lamps, especially the newly popular widely installed energy-efficient LED lights seem to make it worse.

　　A team of researchers from China and the Netherlands have developed a method to assess the impact of uncomfortable glare LED road caused by people, and created a model that can evaluate a variety of lighting conditions, driver discomfort level. Team of researchers from Fudan University, Philips Research Asia (Shanghai, China), human technology interaction group, Eindhoven University of Technology and Philips Research Laboratories (Eindhoven, The Netherlands).

　　Discomfort glare is notoriously difficult to characterize, glare study conducted by Shanghai Fudan University and Eindhoven University of Technology to China, the focus is to find cause discomfort glare, the key factors leading to the need to avoid the eyes of the human face of the light source, which the team set up a laboratory to simulate the street lights work scenes, volunteers observe simulated 72 different lighting conditions. Associate professor at Fudan University, said: "With the development of LED industry, no doubt, more and more LED lights will be used for road lighting, we believe, in the lighting industry due to the urgent need to update the characterization of discomfort glare LED road lights the way .
