본 발명은 가로등용 발광다이오드 램프에 관한 것으로서, 상세하게는 방열효율을 높일 수 있으면서 배광각이 넓은 가로등용 발광다이오드 램프에 관한 것이다.The present invention relates to a light emitting diode lamp for a street lamp, and more particularly, to a light emitting diode lamp for a street lamp having a wide light distribution angle while improving heat dissipation efficiency.

일반적으로 가로등은 차도와 인도를 포함하는 넓은 영역에 대해 광을 조사할 수 있도록 지면으로부터 수미터 또는 10미터 이상의 높이까지 연장된 가로등주 상에 램프가 장착된 구조로 되어 있다.In general, street lamps have a structure in which lamps are mounted on street lamp poles extending from the ground to a height of several meters or more than 10 meters so that light can be irradiated over a wide area including a roadway and a sidewalk.

Since the assembly is good, the heat generated from the light emitting diode 161 can be radiated through the unit housing 151 and the main housing 110 can be improved heat dissipation efficiency.

또한, 메인 하우징(110)에 각 단위 발광유니트(150)가 상호 다른 조사각도 방향으로 장착되되 전체적으로 방사방향에 대한 확산각이 넓어지게 장착되어 있어 넓은 확산각을 제공할 수 있다.In addition, each unit light emitting unit 150 is mounted on the main housing 110 in different irradiation angle directions, but the diffusion angle in the radial direction is wider to provide a wider diffusion angle.
