          LED street lighting field dynamic measurement method

          In addition to the functional role of lighting, color rendering has become more and more the focus of attention. In general lighting, especially in urban road lighting, the increase in color rendering can greatly increase its safety performance. Tang Guoqing, general manager of CREE China, pointed out that after using LED street lights in Guangzhou Avenue, the road brightness can reach more than 2 cd/m2, the longitudinal uniformity is 0.7, the color rendering index is above 75, and the energy saving is over 40%. Through the replacement of LED street lights, the traffic accident rate and crime rate have greatly decreased.

          At the "6th LED Industry Theme Summit Forum" hosted by Gaogong LED, Ye Rongnan, a professor-level senior engineer of the Fujian Optoelectronic Industry Association, proposed a dynamic measurement method for road lighting. He pointed out that road illumination and road illumination uniformity were used as road lighting. The quality criterion can not faithfully reflect the true feelings of the human eye. It is necessary to create a vehicle dynamic field test equipment and establish a more objective, simple and accurate measurement method to evaluate the road lighting quality.
