New LED street lighting system allows more energy-efficien

　　Although the city lights to illuminate the road , but at the same time, it also brings a lot of light pollution and energy waste, but it has been criticized though but no solution. However, according to reports, at present there is a group composed by the China Taiwan and Mexico, researchers developed a new LED lighting system, which through the efficient use of LED lights, LED lights can only illuminate the need to ensure a place of light , without generating additional unnecessary light.

　　The new LED lights system, a unique feature : it can adapt to different street layout , for a variety of streets and roads to provide efficient lighting.

　　This new LED street lighting system consists of three parts . The first part contains a list of the light emitting diodes , each of them is equipped with a device is called a TIR , its role is to bring together the light , precise control of the beam direction , so that the light is emitted parallel to each other will not intersect .

　　The lens is mounted in a reflecting cavity , the role is to recycle light , to ensure that they can be used to illuminate a target more , which is the second part of the system . The third part is the outermost layer of the light filtering means , which is to reduce the unwanted glare. With this unique structure , the researchers can control the shape of the beam , the current preliminary design of a rectangular beam shape , very suitable for road lighting.

　　Researchers use light utilization (OUF) to quantify the performance lights , LED street light utilization higher the better the performance . Computer simulation results show that the new street lighting system light efficiency can reach 51% to 81 %, far more than the current 45% of ordinary street . In addition, compared with the traditional lights , this new LED lights brighter , more energy efficient , easy to produce glare and light pollution.
