Taiwan Institute of road lighting and LED street lamp standard

Energy is twenty-first Century global concerns, energy-saving lighting was listed as the first problem, from the point of view of road lighting is divided into four categories, respectively, the general car streets, shops and sidewalks, road lighting and generally refers to the automobile special lighting.

Importance of road lighting based on Taiwan Industrial Technology Research Institute for energy saving technology business group deputy leader Li Liling in the conference report, road lighting design considerations include adequate illumination, uniform brightness, color and pleasant, avoid glare, induced traffic, energy saving and convenient maintenance etc., so the lamp must good performance reliable and safe. Secondly, the lamps with high efficiency, good lighting utilization, appropriate distribution of light, long life, waterproof and dustproof, in order to provide safe and reliable, energy saving, visual comfort, low light damage and low maintenance rate. Finally, the trend of decorative lamps, street lamps, modeling and aesthetic features of local culture, and then with the appropriate arrangement, reduce the number of poles and maintain a uniform surface light, to reduce the cost of setting up, add beauty.

Dr. Li Liling believes that the road lighting is strictly required, global in road lighting and street lighting specifications set performance standards quite complete and clear; the standard generally consists of illumination and uniformity (minimum illuminance / average illuminance), the International Commission on illumination (CIE) of the proposed CIE115 reference standard, the road will be divided into four categories, the road in 15, 20, the reference illuminance uniformity and 30 50Lux (minimum illuminance / average illuminance) 0.4, but environmental and cultural factors based on the consideration of national norms, there is still a considerable gap. With the standard of road lighting design; (1): Specification for road lighting arrangement, pole height and lamp rod spacing design; (2) the use of road lighting lamps: regulate the lamp type and light distribution requirements; (3): Specification for road lighting lamp pole strength requirements; (4) testing standards light and ballast; (5) lights with photoelectric automatic extinguish test device.

Dr. Li Liling in the report, announced confidently, white LED has developed rapidly, the light utilization rate and environmental protection and other advantages, make LED lamp technology a few years quickly improving, the luminous efficiency is higher than the mercury lamps more than 25%. LED light source technology improved rapidly in the past three years, 100LmW has high luminous efficiency, high power and high brightness on demand street, LED street lamp heat is still high, there are doubts about the reliability; secondly, in the street to meet the safety, road illumination, uniformity, glare and other needs, LED lighting the optical design of technology to solve. Furthermore, LED lamp price is higher than the traditional lamp several times, so the comparison in various parameters of energy efficiency, performance and cost, LED Street development international companies more conservative, but LED lighting with energy saving potential, and road lighting utilities belonging to the government, at all levels of government pay more attention to environmental protection and energy saving trend, the future of LED street lamp Unlimited Business Opportunities.
