The history of street lighting development.

Modern distance lighting began with the emergence of incandescent lamps. Distance lighting is following the development of the times, the progress of science and technology and the continuous progress of our living standards. From the fact that we only request lighting, we can find out the distance of the road, to help us recognize the distance is pedestrian or obstacle, and then help the drivers of motor vehicles and non motorized vehicles to distinguish the characteristics of pedestrians.

Street lamp manufacturers were the earliest street lamps, and then appeared high-pressure mercury lamp, high pressure sodium (HPS) lamp and metal halide lamp, high efficiency energy-saving lamp, electrodeless lamp and LED lamp, etc.. In today’s sophisticated CF street light, HPS lamp light effect is the highest, up to 100~120lm/w, in today’s China full distance lighting Mall (with a capacity of about 15 million, high pressure sodium lamp) occupies more than 60% market share.
