Taiwan institute pointed out that road lighting and LED street light standards

Energy is the 21st century the world's most concerned topics, lighting energy saving more is listed as one of the first question, from the perspective of lighting road is divided into four categories, respectively is dedicated, generally the streets, shops, street and sidewalk, and generally refers to road lighting, special lighting.

based on the importance of road lighting, Taiwan industrial technology research institute in Dr Li-ling, energy-saving technology group deputy team leader at the conference said in a report, road lighting design considerations include sufficient illumination and luminance uniformity, light color and pleasant, avoid dazzle, induced traffic, energy saving and convenient maintenance etc. , so street lamps have to performance better, reliable and safe. Second, lamps and lanterns with high efficiency, good lighting efficiency, and appropriate light distribution, long life, waterproof and dustproof, etc. , in order to provide safe, reliable, energy saving, visual comfort, low light pollution and low maintenance rate, etc. Finally, trend of decorative lamps and lanterns, lamp modelling is beautiful with local cultural characteristics, again tie-in appropriate arrangement, reduce light pole number and maintain the road light even, to reduce cost, add beauty.

li-ling, 'says Dr. Road lighting is strict requirements, global in road lighting set specification and street lamp fairly complete clear performance standards; Standard generally contain intensity of illumination and uniformity ( Minimum illumination/average illuminance) , the international commission on illumination ( CIE) CIE115 puts forward reference standard, the road is divided into four categories, road illumination datum points, 15, 20, 30 and 50 lux, evenness ( Minimum illumination/average illuminance) For 0. 4, but based on the environmental and cultural factors, there are still quite a gap between national standard. The relevant standards of the road lighting design; ( 1. ) Road lighting specification lamp array, light pole height and spacing interval design; ( 2. ) Road lighting used lamps and lanterns of the street light type and light distribution requirements; ( 3. ) Road lighting lamp standard specification lamp pole strength requirements; ( 4. ) Light and ballast testing standards; ( 5. ) Street lamp with photoelectric automatic point out the unit tests, etc.

in the report, Dr Li-ling confident announced that the rapid development of the white led, the light utilization and environmental protection advantages, make rapid ascension, led street lamp technology a few years has been higher than that of mercury lamp luminous efficiency more than 25%. LED light source technology in the rapid promotion in three years, 100 LMW has high luminous efficiency, demand for high power high brightness of street lamp, LED street lamp calorific value is still on the high side, have doubts about the reliability; Second, street lamp under the security considerations, to meet the road illumination and uniformity, the demand such as glare, LED lamps and lanterns light distribution design technology needs to solve. Moreover the LED lamps and lanterns price several times higher than traditional lamps and lanterns, therefore, in the energy efficiency, cost and performance under various parameters, such as international companies LED street lamp development is conservative, but have the potential to LED lighting energy conservation and environmental protection, and belongs to the government utility road lighting, governments at all levels to the trend of energy conservation, environmental protection and the growing emphasis, LED street lamp infinite business opportunities in the future.
