Dr. Wang Yang, deputy general manager of Cedar,

During the 8th Jilin lighting science and technology award awarding conference and northern city lighting (Changchun) forum held on April 27, 2017. Experts, scholars and enterprise representatives from all over the country gave wonderful speeches on new lighting concepts, new products and new technologies.

Dr. Wang Yang, deputy general manager of Cedar, has won the unanimous approval and warm praise from all experts and industry personage on the spot for the "brief analysis on the development direction of urban road lighting" preached by forum.


Dr. Wang Yang's speech starts from the development direction of urban road lighting. LED technology has entered the field of road lighting for nearly ten years, and the focus of technical research is mainly on improving efficiency and solving cost, but the problems of people-oriented maintenance, safety and comfort are still unsolved.

China's latest implementation of the "CJJ45-2015 urban road lighting design standards" in 2016, clearly requires that urban road lighting should give priority to the use of LED low-color temperature light source. However, the LED street light source applied in the market at present is still dominated by high color temperature due to its inability to break through the technical bottleneck. In China, there are many rainy and foggy days in the south, while in the north, due to environmental pollution and haze, the weather tends to be normal. LED street lamps with low color temperature have strong fog-penetrating ability and are less affected by climate. Compared with the traditional light source, it is more helpful to improve the comfort of human eyes, and at the same time to avoid the blue light harm caused by the high color and temperature light source to human eyes, eliminating the driving safety hidden danger caused by excessive tension, fatigue and uncomfortable glare.

Dr. Wang Yang believes that the light environment of urban road lighting in the future should be developed around safety, comfort and energy saving, Therefore, from the design of illuminator product itself, it should be the combination of energy saving and standard (guarantee the average illumination of road surface)+ low color temperature (guarantee the light penetration)+ easy maintenance and interchangeability (guarantee the interchangeability with sodium lamp)+ intelligent (guarantee the centralized control and energy saving).
