University of Manchester, UK studies new LED road lighting technology

It is reported that the United Kingdom is reported that the University of Manchester and a lighting company are working together to study the advantages of LED technology in road lighting.
It is reported that the University of Manchester and a lighting company are working together to study the advantages of LED technology in road lighting.
LEDs have a long life expectancy, and the LED street light modules under study have a life span of more than 10 years, which is more than four times the life of ordinary street lamps. The long life of LED street lights means that there is no need to change them frequently, which reduces the potential for traffic disruptions and reduces the maintenance costs paid by the government for this purpose.
If LEDs are used to provide illumination, energy consumption can be reduced by 25% to 50%. But when 12,000 lumens (a typical 60-watt bulb is 800 lumens) or more is needed, heat and other electrical-related problems can be an obstacle to LED technology.
The challenge that researchers are now trying to solve is how to reduce the amount of heat generated by a group of LEDs that are tightly packed together. Since LED modules can be used outdoors, it is also necessary to take into account actual environmental factors, such as the possibility of nesting birds on critical heat sinks. There is also a regulatory issue. The current regulations stipulate the glare of the lamp and the light pollution limit, and clearly define the area where the LED light source can be installed. These are all challenges.
Under normal operation, the LED undergoes a process in which the light output is gradually reduced, and this process continues. The reason for the decrease in light output may be due to the reduced efficiency of LED light production or due to the reduced light path within the LED compression package. However, as long as there is no overload, LED street lights can reach 70% of the original light output after 50,000 hours or 10 years of operation.
