For example, we recently invested about 2 billion won in Yanggu-gun, Gangwon-do to replace the light source installed in existing street lighting with LED, and more than 600 cities in the US replaced the light source installed in existing street lighting with LED . In addition to lighting for street lamps, fluorescent lamps using conventional fluorescent lamps have also been replaced by LEDs. Fluorescent lamps that use LED as a light source are attracting attention as so-called EL light.
