The government should guide the less heavy intervention for LED Street light

   "High pressure sodium lamp and high pressure mercury lamp coexist for ten years. If you really want to change, I think the ceramic metal halide lamp LED light than good. "In Vincent prof, LED strip light, underground led light, r7s led as the light source is good, but as a street lamp are subject to the development of five or six years time, wait for the market really mature, LED street light quality also need to be better and better.

  "The advantage of LED street lamp has not been play. LED lamp is adjustable light, can dynamic operation, and the traditional HID will not." Fudan university lighting engineering, formerly China lighting academy ZhuShaoLong consultant, says professor LED street lamp intelligent lighting is the best way to use. "When a car lights, car go back light dark, foreign some cities have begun to use such technologies. The current domestic enterprise may have reached this technical requirements, but it needs sensor control, capital investment, so it doesn't have example applications."

  At this stage to see, in the technical LED street light than in previous years and no new idea, in addition, in the efficacy and cost performance, evaluation and so on many key indicators LED street lamp also has more controversy.

  "LED is a point light source, if the application is not good, is easy to appear the glare problem. And, from the whole industry chain to see, LED street lamp involves radiator, drive, high-pressure sodium lamp replacement down all the cost is not necessarily more money." Hangzhou mingda photoelectric LED products research institute WuMingFan think, LED street lamp for high technical requirements, the mass change still need fastidious.

  In addition, the evaluation of road lighting index adopted "illumination" rather than "brightness". ZhuShaoLong professor pointed out that only when the distribution of light to bat type distribution of light, intensity of illumination to replace brightness. And the actual situation is due to the intensity measuring instrument price expensive, popularizing rate is not high, so in order to convenient, usually use illumination instead of brightness. Evaluation system existence of loopholes, LED street light quality also difficult to guarantee.

  To promote the government's strong LED lighting renovation project, enterprise have their own views. "The government's push, subsidies can be solution enterprise burning issue, but can be fundamentally save enterprise must be different. The government project whether the product qualified, also can only rely on time to test." Hangzhou red sword made Ming technology co., LTD., general manager of zhangfeng concerns, the government take temporary solution not effect a permanent cure, and too much administrative intervention may let the LED industry to become "the second pv". At the same time, he also pointed out that in the face of such a blundering market, enterprises need more clear their development direction, and not by the support of the government of the project or so.

  "Of course, the support of the government of LED industry is to have certain help, from on macroscopic to promote the development of the industry. But the present situation is that the local government heavy price, not heavy quality, and not from the point of view of whether benefits. The market was" turbidity ", the lack of a guide intervention would be more stirring the mix. someone worried.
