Bo said the cause of the emergence of the overpass is to ease the city's traffic congestion, improve road conditions. Because the complexity of the bridge overpass special line, and a large multi-path variation, prompting security to lighting overpass More research LED lights factory production strength, and general road lighting are not the same, not only to consider the use of LED lights, etc. illumination, energy issues, taking into account security issues, design and technical issues are more worthy of long to explore, there are a lot of room for improvement. Study on the road is not too much lighting designer may not be able to intuitively understand the issue of road lighting overpass. Now we summarize some of the characteristics and overpass lighting-related facilitate a better understanding of this article: overpass mostly full interoperability multilayer composite, the interchange of several roads, the vehicle type will have a limit on the Road ; distinguish different directions the main road, turn left, right line ramp and other channels, both corners have split vent bridge; spacious deck also composed by a plurality of lanes, the whole bridge also has a different style. Although the overpass bridge complex, to see at night it is a beautiful landscape in the evening, but if you can not guarantee the security of the overpass street situation, will result in a serious accident. Before heard architecture professor Wang and "China Illuminating Engineering Journal" on road lighting research on speech. People on the road, especially when driving on the overpass, the use of lighting on their own to see the lines, roads, surrounded by vehicles, pedestrians, and other information processing orientation, make sure you make the right judgments and travel operation, to ensure that the driver that, as road lighting designers to take into account the disability glare (ie, the brightness of the light curtain), human reaction time and other lighting parameters. Bo tells cause "as a substitute for natural light and artificial light for photosynthesis, the wavelength LED light source can be selected, the power can be adjusted." Deputy Director, Institute of Semiconductors Hongda Chen said, "it is possible to selectively provide different plants different wavelengths, intensity and duration of exposure, high flexibility. "Hongda Chen said that despite the current LED lighting applications in agriculture is still in its initial infancy, but with an artificial light source LED intelligent control the growth of crops, changing the traditional The agricultural production, has a very good development prospects. It is understood, LED light source spectrum required for plant growth through simulation, not only allows the plant can grow all the time, but is also effective for stable flowering. Currently, few companies try to do this, and in the country know how LED street price, the three safety photoelectric be the first to eat crab. "In addition to helping plant growth, reduce pests and diseases, ambient temperature control, LED lighting can also control the flowering time." Sanan Optoelectronics Technology Center, a name off official said LED lights where to find the best, "the use of LED flowering lamp , growers can flower opening hours will be adjusted to take the highest price to obtain higher profits, such as Valentine's Day and so on. "The problem is that basic research and cost bottleneck" when the plants were artificial lighting LED lights, different plants require different wavelengths, The same plant in different growth periods, such as germination, flowering, the results, their needs are not the same wavelength. "The name off official said," but the current domestic-related research is also in its infancy, it needs light for plant growth the specific needs of the wavelength, intensity, time, not to mention it, even if the domestic LED industry with the relevant technical, difficult hero have its uses. "how to buy LED lights, the great cause of (certified), LED lights from Henan cause Bo lighting equipment Limited. Henan cause Bo Lighting Equipment Co., Ltd. (www.zzdybcdj.com) is Zhengzhou City View light fixtures leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the cause of the leadership with the staff warmly welcome all inquiries negotiations to create the great cause of a better future.
