LED area light source technology found breakthrough in Nanjing

LED lighting technology is more advanced than traditional lighting in energy consuming, environmental protection and health-hazard aspects. The current used lighting source for LED lights is so called “spot lighting source”, which has some defects: inevitable lighting attenuation, higher costs and poor performance of cooling sections. These defects exerted a bad effect on their promotion process. With the becoming mature of LED chip technology, “area light sources” are no longer a myth. Then designers and LED engineers started to realize that replacing spot light sources by LED area light source technology is a key point to overcoming the defects of the existing LED lighting products. Under the support of the “Nanjing 321 plan” issued by Nanjing Government in last month, LED area light source technology found breakthrough in Nanjing.

 

LED area light source technology found breakthrough in Nanjing

 

In the Science and Innovation Park of Nanjing University of Technology reporters found this “area light source”. Nanjing XiongYan Optoelectronics Technology Co., Ltd. demonstrated a recently developed table lamps used LED area light source technology. Only judging from the space, this table lamp has nothing special, just like an ordinary table light. However, it is amazed that this LED table light has no bulbs but still can emit soft yellow white rays.

 

“All light are coming from this small light-emitting sheet.” Introduced by Mr. Guohua Bian, general manager of Nanjing XiongYan Optoelectronics Technology Co., Ltd.. On his palm we found a tiny circular sheet (with a diameter around 4cm, with a wideness about 1mm, and covered with yellow phosphor powder and small black spots), which is rather unnoticeable. “Each black spot is a lighting source. All these 3000 thousand small lighting sources have been evenly arranged on this sheet. We called it are light source. Every sheet consumes a power of 3W, but can replace a 20W traditional table lights. This table light has been installed 10 pieces lighting sheets just like this one, which means this lamps are equivalent to a 100W filament table lights. ”

 

In Mr. Bian’s words, his company spent totally 30 million yuan on developing LED area light source technology. It is a light source technology that more advanced than spot light source, less light attenuation, more easily-be-realized cooling design.
