Fireworks in March under Yangzhou, China Lighting Association, China Lighting Association Outdoor Lighting Professional Committee, China Municipal Engineering Association Road Lighting Professional Committee jointly held the 2008 China Road Lighting Forum in mid-March in the beautiful Yangzhou. More than 400 people including production companies, industry experts, academics of higher education institutions, municipal management committees of various provinces and cities or road management offices attended the meeting. The participants have gained a lot of money. Everyone thinks that the forum has set up a platform for communication, production, research, research and user units. The participants conducted in-depth and extensive discussions on the problems in the development, production and use of road lamps through the forum. Production enterprises and user units have a comprehensive understanding of the technology, development trends and usage of road lighting. However, the tendency that appears in the forum makes people feel deeply and does not spit.
The theme of this forum is the implementation of road lighting energy-saving technologies. There are many ways to save energy in the process of road lighting. The energy saving of road lamps themselves, including the design of reflectors, the use of electrical appliances, and the choice of materials, there are many jobs that can be done by lighting manufacturers. However, in the process of the forum, whether it is a production enterprise or an expert, a scholar, or a user, the LEDs are used in road lighting. The 28 products produced by the forums in the forum are also all-in-one LED lamps. The extent to which LEDs are currently hot in the domestic lighting sector is evident. Some people say that the 2008 China Road Lighting Forum is a session of LED road lighting.
There are two views on the use of LEDs in road lighting in the forum. These two views have collided in the forum. According to one view, LEDs currently have a large gap between their luminous efficiency, color temperature and high-pressure sodium lamp ratio. They are used as decorative lighting and some environmental lighting. For example, as road lighting, it is currently only suitable for hospitals ( Park) or secondary roads, but as a functional road lighting (main road) there are still many technical problems to be solved (such as temperature rise, secondary light distribution, uniformity), it is not suitable for main road lighting. Those who hold this view do not deny the application of LE D in road lighting with the development of LED technology in the future; another view is that (the majority of enterprises), although the luminous efficacy of LED is lower than that of high-pressure sodium lamps, it is effective. High light, as the light requirement of road lighting is enough, and color temperature is only a habit problem. In addition, the company believes that the LED front end has passed the patent monopoly abroad. In the research and development of LED road lamps, domestic enterprises must go ahead, and there should be no road lighting patents. The phenomenon of foreign companies preempting. The collision of the two viewpoints makes the representatives of the conference, especially the user units, have a comprehensive understanding of the current situation of LED road lamps.
I personally think that LED as a new type of energy-saving light source is very suitable for China's long-term national policy of energy saving and emission reduction. I believe that with the development of its technology, it has a huge application space in the field of lighting. However, LED light sources are still in the development stage, and many of their technical problems have yet to be resolved and broken. As a lighting manufacturer, we should pay attention to the development of LED light source. According to the technical level of LED light source, scientific, reasonable and timely development and production of lamps that match the LED lighting characteristics should not be blindly invested. A realistic phenomenon can explain the problem. There are hundreds of existing lighting manufacturers in China that are developing and producing LED road lamps. How many roads can you see in the city using LED road lamps? Although the roads use LED lamps, the current comprehensive reflections are not ideal. Production companies should not only focus on LED road lighting. At this stage, many indoor lighting can fully use LED lamps, but the company's efforts and funds in this area are far lower than road lamps.
