British researchers to overcome the road lighting technology LED

It is reported that the United Kingdom and University of Manchester is working with a lighting company to study the use of light-emitting diode (LED) technology advantages in road lighting.

Use LED to provide lighting the way to reduce energy consumption by 25% - 50%, but when 12000 lumens (a typical 60 watt bulb is 800 lumens) or more lighting, heating and electrical issues will become the obstacle that restricts LED technology.

Now the researchers are trying to solve the problem of how to reduce the amount of heat produced by a compact set of LED. Because the LED module will be used outdoors, it is also necessary to test the actual environmental factors, such as the possibility of the key heat sink birds nesting. There are rules and regulations. The current regulations specify the degree of glare and light pollution restrictions, while clearly defined LED light source can be installed in the region.

Under normal operation, the LED undergoes a gradual decrease in light output, and the process continues. The reason for the decrease in light output may be a decrease in the efficiency of light generation by LED, or a reduction in the optical path of the LED compression package. However, as long as there is no overload, LED street lamp in the work 50 thousand hours or after 10 years, you can also achieve the ability of the original 70% light output.
