Shanghai thinks carefully become standard of highway LED floodlight to draft an
From;    Author:Stand originally

Make a standard with top-ranking enterprise, in semiconductor illume this burgeoning domain appears particularly important. For this, shanghai thinks carefully already go ahead of the rest one pace. Shanghai thinks carefully is industry of application of LED of chinese mainland traffic, 佔 of information board market has the LED alterable information of the company lead 60% above, lead position is in in application of illume of traffic industry LED, apply Yu Yunna, Jiangxi, 陝 successfully already on the west, many freeway of Fujian, Zhejiang, Shanghai, among them lamp of tunnel of highway of Jiangxi Jing Ying only eucalyptus is certainly traffic Department of Transportation is energy-saving decrease a platoon to set an example only eucalyptus.

Shanghai thinks carefully is unit of director of chapter of indication application of LED of guild of Chinese optical photoelectron, information board market possesses the LED alterable information of the company lead 60% above, lead position is in in application of illume of traffic industry LED, apply many freeway of Yu Yunna, Jiangxi, Shaanxi, Fujian, Zhejiang, Shanghai successfully already, among them project of lamp of tunnel of highway of Jiangxi Jing Ying is certainly traffic Department of Transportation is energy-saving reduce a demonstrative item.


Illumination luminaries of JT2008-06 highway LED makes facilities of engineering of traffic of 2009 whole nations (highway) mark appoint three Cisco ability of meeting Shanghai expand limited company

Center of development of Chinese photoelectricity technology Professor Chen Zhegen published a problem to be " a few considerations that illume of road of the “ that draft allows ” with LED beacon light " report, in the report, professor Chen Zhegen alleges, advocate in recent years energy-saving fall bad news, the Ministry of finance and national hair appoint made what popularize to efficient illume product urge policy, released jointly 2007 " fund of allowance of finance of promotion of efficient illume product runs temporary measure " , LED lamp already was included energy-saving product range.

Professor Chen Zhegen thinks, as a result of the characteristic of LED lamp, put forward design and when making, should make the luminous flux of the lamp is centrally in horn of effective beam of light, and the uniformity that must keep certain. To light intensity distributinging uniformity requirement is to ensure essentially uniformity of road surface intensity of illumination (or uniformity of road surface brightness) , it involves quality of road surface lighting not only, and matter to energy-saving. Road surface intensity of illumination is evener, to the average intensity of illumination of road surface the requirement also can be reduced relatively some. Distributing to these luminosity requirement, LED street lamp comes true more easily than street lamp of traditional only light source.
