Problems existing in the development of LED road lighting

Abstract: in recent years the rapid development of LED, many of the world's city in the popularization of the LED, the implementation of energy-saving LED lights to the transformation of traditional street lights and the country also have on road construction, also is the use of LED lighting products. Although, LED road lighting market prospects considerable, but at present, LED road lighting there are still some problems, including the standard, technology and marketing and other issues, LED road lighting really want to completely occupy the market, may also need to solve these problems.

1, standardization problem

Now there is an international organization launched a road lamp standards, and in the country has not yet formed a perfect industry standards. Now do a lot of LED street lamp manufacturers, and each manufacturer's module is not uniform. Without standardization, there will be a series of problems in the process of production, distribution, use and so on. Because different manufacturers of products, whether it is light or electrical appliances, especially the size of electrical appliances and joint drive, such as current, voltage classification, are not the same. If after a period of time manufacturers bankruptcy, then if the application of lighting problems can not find the corresponding replacement products. In the promotion of LED process, the standardization problem is worthy of attention.

2, LED energy saving problem

LED energy saving is now discussed very much, LED is indeed energy-saving, but it can not be generalized. Its energy to what extent, the main look at its opponents, but also depends on the use of the model. The reason why LED can be used as a street lamp is that it is better than the traditional one, so it can be used as an alternative light source. The most important part of the road lighting is dimming, at present, the traditional light dimming only half, LED lights can be transferred to 5%-10%, which is one of the LED lights better than HPS lights.

However, the light should be based on different periods of traffic flow to adjust the light, LED street lights can save energy depends on the size of traffic. The street light control light with traffic flow, which is advanced in the country, but also the embodiment of the advanced LED street lamp. Now the International Commission on illumination CIE115, the new guidelines formulated by considering road classification, traffic flow, traffic, there is no cross road information data, the lane is divided into M1-M6 grades, different grades have different requirements for lighting. Therefore, many people in the industry hope that the country can develop the appropriate road classification as soon as possible, which will be a great help for LED street lighting applications.

3, LED precision light control problem

One of the reasons many people in the industry to promote LED is now LED can control precision, HPS lamp light control is not accurate, so that the light "run" across the street and a waste of energy, and the precise control of LED lamp light can control the light in the irradiation area, thus saving "unnecessary" light. But the biggest problem with this theory is the lack of consideration on both sides of the road. According to an international large manufacturers to do the experiment, 78% of people think that the road on both sides of the light is comfortable, there is no light people feel uncomfortable, both sides of the road can bring a sense of security. This is very important, not only to consider the issue of energy conservation, road lighting transformation to master this degree".
