LED light source is not suitable for large-scale promotion

3 years Shanghai all the landscape lamp will be using the new light source? Recently, the frequent occurrence of this message on the Internet so that experts have repeatedly shook his head. The city sanitation bureau landscape management office director Guo Hua said that although the LED ("led" English abbreviation) new light source has become the city landscape lighting field ", but under the present circumstances, should not be a large-scale promotion set. Even overcome the technical and cost bottlenecks, once the landscape lights are dominated by LED light source, it will cause the night of the landscape light monotonous, lack of sense of hierarchy. Only the combination of the traditional light source and LED light source, in order to create the perfect Shanghai lighting night.

LED has many advantages such as energy saving, environmental protection, the market began to appear "herd" trend. In this regard, Guo Hua believes that large-scale promotion is not possible, it is difficult to achieve the basic goal of replacement within 3 years, because the large-scale application of LED light source in the construction of landscape lighting conditions are not yet ripe.

At present, China's LED product development and technical level is still relatively low. At the same time, its high cost, short term price is not high, non general business can afford. Yu Wei said that the same intensity of illumination, LED product prices of up to 200 yuan, while the price is only ten yuan fluorescent lamp.

Codimension also believes that LED is mainly in the light point, unable to form a line, is not suitable for large lighting system. If the large-scale application of LED, can only make the buildings become a luminous point. The old, solemn building if all the high light LED light source, will lose the original flavor, the whole city landscape is lack of layering and subtle beauty, and become out of order, may also bring new light pollution. But in the small environment and local lighting, LED has an absolute advantage.
