LED road lighting

LED lighting products should be in a deep understanding of LED light source based on physical properties and the needs of the users are highly combined, such as human sensation of light combination, with the use of the combination of environmental, develop truly humanized lighting products, and reasonable optical design is a important aspect.
According to the insiders, LED road lighting after several years of exploration and development, the application process of accumulation of technology and product improvement, at present the market continued steady growth, its development opportunity to show. In the eighth session of the China International Semiconductor Lighting Forum" LED road lighting market and technology applications" summit, many technical experts, corporate executives gathered, separately from the use of the environment, optimization design, the feelings of consumers and how the LED light source for scientific evaluation and other aspects of how LED better application in road lighting, how to get more secure, more comfortable road lighting environment. From which we can feel LED road lighting technology and product application to more in-depth, more humane direction of a big step forward.
LED road lighting road lighting products need to follow the relevant technical specifications, to meet the ground irradiance and regional brightness and other related requirements. LED manufacturer is concerned with the output efficiency of light, but for the users, the ultimate concern is the human eye under specific circumstances to feel the quality of lighting, the light efficiency and light quality exists between a conversion coefficient, the coefficient is related to the environment, so the road lighting products before installation need to do a lot of specific research work, can't take a standard everywhere use.

Several commonly used optical design methods are: ( 1) using the structure adjustment of light, is light monomer into array, the lamp panel tilting device, in order to adjust the required light distribution. The optical design of the biggest advantage is low cost, but to meet the higher light quality is not easy to achieve, but also can do single between each different tilts, make overlay the light meets the needs of street lamps. ( 2) with the two optical design, the use of a single in vitro optical design elements, such as the reflector or lens, so that the beam reaches the desired light distribution. It can bring monomer standardization, has high flexibility, can be LED monomer and optical design separately, makes the design more flexible, to meet the different requirements of the road environment. ( 3) using an optical element, in the LED monomer directly with package lens oriented single output light type into the desired distribution form, this kind of design can reduce the inconvenience in structure design. In the road direction on the asymmetric distribution of available light plate tilt or light lens design to achieve, so can simplify the integration, but the cost of design and manufacture cost is high. ( 4) using optical device, found only in the patent, but the product is not used, the design method of optical loss and is easy to repair, can meet the high optical quality requirements. The future road lighting requires the integration of these technologies, but also into the command and control technology and network management technology.
Talking about the LED road lighting challenges, we will usually refer to product quality challenges, such as life, reliability, failure and the investment rate of return. But the product is for lighting services, the end user is concerned there is no glare, sidewalks, is it right? Too dark, white is comfortable, whether the illumination is higher. Energy saving is not only the product itself, energy saving, more important is the application effect of energy saving, is based on the safe and comfortable lighting environment on the basis of a comprehensive consideration of index.
Road lighting to road safety services, first of all need to meet the basic needs of security.
