The energy is the topic deeply most concerned in the world in the 21st century, lighting energy-conservation is classified as the first question even more, divided into four big classes, including specialized, general street of the car, shop street and pedestrain way from the lighting view road, and the road lighting that generally refers to is the dedicated illumination of the car.
On the basis of the importance of road lighting, living trader vice group leader Dr. Li Lilin of power-saving technology group of research institute calls the industrial technology in Taiwan in the report of this conference, the lighting design consideration of the road includes the illumination intensity sufficiently, with even brightness, the light color is pleasant and avoiding the glare, inducing driving a vehicle, energy-conservation and safeguarding the facility etc., so the necessary characteristic of the street lamp is good, reliable and safe. Secondly, the lamps and lanterns possess the light distribution, longe-lived, waterproof and dustproof, etc of high efficiency, illumination with good, appropriate utilization factor, in order to offer safe and reliable, energy-conservation, vision comfortable, low-light hurting and low rate of maintenance,etc.. Finally, the ornamental trend that melt of the lamps and lanterns, the model of the street lamp stresses esthetically that there are local culture characteristics, and then match appropriate permutation, reduce the rod number of the light and keep the light of road pavement even, reach and reduce the cost of set up, add aesthetic feeling.
Dr. Li Lilin thinks, road lighting receives the rigorous requirement, it is quite intact and clear that the whole world sets up norm and street lamp performance criterion in road lighting; The standard generally includes illumination intensity and even mode (minimum illumination intensity / mean illumination) ,International Commission on Illumination (CIE) CIE115 propose last norm,road last four big class,road pavement illumination intensity datum 15, 20, 30 and 50Lux, even mode (minimum illumination intensity / mean illumination) Require 0.4, but consider on the basis of environment and culture factor, the norms of various countries still have about equal disparity. Cooperate with the relevant standard of lighting design of the road yes; (1.)Road lighting: Standardize the intersection of lamp pole and permutation, the intersection of lamp post and height and pole, design from the interval; (2.)The lamps and lanterns that road lighting uses: Norm every street lamp type and light distribution are required; (3.)The lamp post for lighting of the road: Standardize the intensity of the lamp post to require; (4.)Light source and standard of measurement of the stabilizer; (5.)Method of inspection of optoelectronic type automatic off and on machine for lamp of the road,etc..
Dr. Li Lilin, in the report, very confident declaration, the white light LED is fast growing, mere utilization factor and co dominant in environment protecting mode, let the technology of LED street lamp promote quickly in a few years, luminescent efficiency has already been higher than the mercury lamps and lanterns 25%. LED light source technology promotes fast within these three years, luminescent efficiency has already exceeded 100LmW, as to street lamp of the heavy-duty high light demand, LED street lamp is still a bit high in calorific power, reliability has doubts; Secondly, the street lamp should meet demands such as the intensity of illumination, degree of consistency, glare of road pavement,etc. under considering safely, LED lamps and lanterns light distribution designing technique need to solve. Moreover LED lamps and lanterns price is higher than traditional lamps and lanterns by several times, so, under the circumstances that every parameter such as energy efficiency, characteristic and cost are compared, LED street lamp of the big international factory develops more conservatively, but LED illumination has energy-concerving and environment-protective latent energy, and road lighting is government's public service, the governments at all levels pay attention to energy-conserving environmental protection and trend day by day, the business opportunity of LED street lamp is limitless in the future.
