The present invention relates to a streetlight including an LED lamp. The streetlight includes: an LED lamp (5) which is mounted on a lamp post of the streetlight; an LED element (4) which is arranged on a substrate formed in the inside of the LED lamp (5) and emits light; a reflecting plate (7) which is formed on the LED lamp (5) and reflects light; a lens (9) which surrounds an emission section of light from the LED element (4); an illumination sensor (11) which is formed on the LED lamp and senses the surrounding illumination; a movement sensor (13) which is formed on the LED lamp and senses movement; a fluid spray nozzle part (17) which removes foreign materials by spraying fluid if the foreign materials are piled on the surfaces of the illumination and movement sensors (11,13); and a control unit (15) which operates the fluid spray nozzle part (17) by interlocking with the illumination sensor (11) and the fluid spray nozzle part (17) when the sensitivity of the illumination sensor (11) is within a preset range or less. |
