The present invention relates to a street lamp device capable of adjusting the irradiation angle of an LED module by easily adjusting the angle of the LED module inside a lamp housing of the street lamp device without changing the design or structure of the entire street lamp device. The street lamp device according to a preferred embodiment of the present invention comprises: a lamp post; a connection arm bent from the top of the lamp post at a predetermined angle to extend horizontally; a lamp housing connected to the end of the connection arm; and an LED module disposed inside the lamp housing and having an LED lamp formed on the lower surface thereof. The LED module has two parallel guide pieces formed from one end to the other end of the bottom thereof to protrude vertically downward. A fixed frame is fixed to the lower surface of the lamp housing and hinged to the bottom of one end of the LED module by a pin. An irradiation angle adjustment device includes: a height adjustment bolt consisting of a bolt head and a main body with a screw thread, wherein the bolt head is fixed to the lower surface of the lamp housing to be rotated, and the main body is positioned vertically upward inside the lamp housing; a nut coupled to the height adjustment bolt to move up and down along the main body; and a plate-shaped support bar with a predetermined length, one end coupled to one side of the nut, the other end horizontally formed to be inserted between the guide pieces on the other end of the LED module, and a predetermined width. |
