The large-scale application of LED light source is not mature failed to meet the landscape function

National Day is approaching, Shanghai the Bund, Nanjing road landscape, Huaihailu Road will shine, Xujiahui, Jingan Temple, Yu Garden and some other large lights king will add to the festive atmosphere. So, the landscape lights are likely to be put on the new energy saving LED light source? This idea is in a dilemma: on the one hand, the power consumption of the traditional landscape lamp is quite large, a new source of energy saving and environmental protection needs; but on the other hand, although the new LED light source can achieve energy saving and environmental protection, but also can not fully meet the Shanghai Landscape lamp function and aesthetic requirements. According to the city sanitation bureau landscape management office director Guo Hua introduced, the current domestic traditional city lighting generally uses passive lighting of buildings, power consumption is very huge, so many city in high temperature are forced to limit lighting. The LED is due to its own bright lighting, power consumption is only 1/20 of the way of passive lighting, high power saving effect, and LED long service life, usually up to more than 50 thousand hours.

However, it is not possible to promote LED on a large scale at present, because the condition of the large-scale application of LED light source to the architectural landscape lighting is not mature. At present, China's LED product development and technical level is still relatively low, the cost is high, the price is hinders the development of LED speed." LED, a professor at East China University of Science and Technology who specializes in LED light, also said that because of its structural weaknesses, is not suitable for large-scale lighting systems.

In addition, the current LED is still the main point of light based, unable to form a line. If large-scale applications, can only make the buildings become a luminous point. Especially in the city has a long history and a solemn building if all the high light LED light source, will lose its original characteristic flavor, people everywhere "," dazzling "riotous with colour" feeling, and may bring new light pollution. Therefore, experts believe that only the combination of traditional light sources and LED light source, in order to create the perfect Shanghai lighting night.
