The popularity of LED light of the difficult road to praised

LED light source because of its high efficiency and long service life, since its inception, favored by the market. When the small power LED lighting products in the traffic signs, car tail lights, contour lights and other areas "in the limelight" at the same time, high power LED street lamp above 100W, but because of price, technology and other reasons the market suffered a serious bottleneck. A huge city of Wuhan, only a few hundred meters of the road, leaving the LED street to do self presentation.

LED lamp is only used as landscape lighting

From Hankou Huangxiaohe road to the street of Qing Luan Road, the road two hundred or three hundred meters, standing ten Street, after nightfall is out of the ordinary: the shape is almost ten Jizhan lamps, they emit different colors, different shades of light, from afar, is very strange.

"This road is our test field specially for LED Street ''. "Wuhan city street Bureau biotech section Fang Yong told reporters, a dozen lights on this road are all different manufacturers home LED street selling, to detect whether the quality of clearance, a year ago, standing on the street, using the instrument" to light the way "to test, in order to detect the light the intensity of illumination and lighting duration and energy saving core technology index.

"Why not on the main road with energy-saving LED lamp? "The reporter asked. LED energy-saving light source is the future trend, but the technology is not mature. Fang Yong said that the existing LED street lamp has two technical problems, one is the heat, the two is not enough power, can not meet the national requirements of the main road lighting brightness. At present, Wuhan City, more than 14 lamps light the road, has sixty thousand lights are the traditional lamp, for road lighting, LED street lamp is less than two thousand, used for lighting East Lake road and beach landscape belt.

Fang Yong introduced the LED technology in the laboratory can reach 200LM (LM) lighting brightness. But in practical use, only 30% of the LED street light energy can be converted into light energy, the rest of the energy into heat loss. Therefore, if the current LED street lamp used in the main road, the lighting brightness is not enough.

High cost LED stopped to mass

In addition to the heat problem, there is a threshold is high cost. Reporters learned that the current cost of LED street lamps is more expensive, a 100 watt LED street lights to thousands of dollars.

Insiders told reporters that due to the current LED lighting chip core technology basically controlled by foreign countries, the domestic manufacturers of LED products from abroad will only take back the package processing, so there is the development of intellectual property issues such as cost sharing, chip prices higher.

In addition, LED heat dissipation problem has not been solved effectively, the production enterprises to solve the problem of heat dissipation, self design and mold lamp high costs, also increased the cost of products. The above reasons caused the price of LED street lighting products in the market does not dominate.

Policy is LED street in the promotion of another bottleneck, insiders, although the government and relevant departments at all levels attach great importance to the work of energy-saving emission reduction, but the expensive cost of LED street lamp is beyond the capacity of the government. In addition, if the old road of LED street reconstruction, electricity will inevitably decline, but the electricity sector only to billing, the financial sector can only be truthful account of local government, in addition to the LED street lamp to pay, no benefits.
