In the development of road lighting in China, there has always been competition between “Huangguang School†and “White Light Schoolâ€. The representative of "Huangguang School" is the mainstream high-pressure sodium lamp. Because it is economical and energy-saving, it also has excellent fog-passing performance, so it has become the mainstream street lamp choice in China. "However, Huang Guang has its drawbacks that cannot be overcome naturally: that is, the color reproduction ability is poor." Philips related technical experts recently said.
The goal of the "White Light School" is natural sunshine. Because it has the best color performance, and the sun is a warm white light. Therefore, if you can achieve white light similar to daylight, and at the same time take into account the advantages of Huangguang's economical energy saving, it will be an ideal night lighting option. The "player" of the "White Light" is a quartz metal halide lamp. Although it has more than 3 times higher color performance than yellow light, it is also not widely used due to some insurmountable technical problems.
It was not until the emergence of the "new army" of the "White Light School", the warm white light urban road lighting system, that the answer to the problem of "fish and bear's paw" was found for this problem. The core advantage of the new warm white light is that it is more efficient and consumes less power. The same street light uses at least 10% less electricity than yellow light, reducing carbon dioxide emissions by 40%. Therefore, it meets the requirements of environmentally friendly lighting and green lighting. Now, with the energy crisis and the increasing greenhouse effect, there is great potential for popularization.
According to reports, the concept of warm white light was first proposed by the world famous lighting company Philips, and has been widely used in the United States, Britain, Belgium, Norway and other countries. Philips Lighting and Fudan University began scientific research and analysis of the introduction of the system into China in early 2006. With the support and cooperation of Shanghai Electric Power Company, at present, this warm white light road lighting system has been installed in the famous traffic artery of Shanghai, Xixi Road and the prosperous commercial street, Qipu Road, and entered the testing stage.
