Using LEDs to provide lighting can reduce energy consumption by 25% to 50%, but when 12,000 lumens (a typical 60-watt bulb is 800 lumens) or more is required, heat and other electrical related The problem will become 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.
Under normal operation, the LED undergoes a process in which the light output is gradually reduced, and this process continues. The reason for the reduction 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.
