A light source module 13 that irradiates light through a plurality of LEDs 131 and illuminates the spotlight in the transverse direction by irradiating it in the direction of the diffusion lens 111;
Including; a casing 14 having a hollow cylindrical structure with an open upper portion, mounting the frame body 12 and the light source module 13 therein, and sealing the open upper portion with an upper cover 11; Is to do,
The frame body 12 is integrally connected with the lower surface of the upper cover 11 to form a frame structure protruding downward, but the first protruding from both sides of the head unit 132 of the light source module 13 A support frame 121 comprising a first coupling through hole 121a forming a hinge coupling with the coupling protrusion 132a,
A lower joint 133 formed in the shape of a disk integrally connected to the lower end of the support frame 121, and forms a hole 122a having a square structure at one side to support the head portion 132 of the light source module 13 ) And a lower plate 122 providing a rotational space,
It includes a third coupling through hole 123a which protrudes downward from both ends of the hole 122a formed in the lower plate 122 and is hinged with the third coupling protrusion 133b of the lower joint 133 In the intelligent short-range spotlight system for pedestrian safety at night pedestrian crossing comprising a protrusion 123,
The light source module 13 has a head unit 132 having an open housing structure and a plurality of LEDs 131 installed on the inner side thereof,
As including a lower joint 133 that is fastened to the head portion 132 in a hinge structure to rotate within a predetermined angular range while supporting the head portion 132,
First coupling protrusions (132a) are formed on both sides of the head portion (132) to form a hinge coupling with the first coupling through hole (121a) of the support frame (121), while a second coupling to the rear surface of the head portion (132) A through hole 132b is formed to form a hinged connection with the second coupling protrusions 133a formed on both sides of the upper end of the lower joint 133,
Third coupling protrusions (133b) are formed on both lower side surfaces of the lower joint (133) to form a hinge connection with the third coupling through hole (123a), and the first coupling protrusion (132a) and the first coupling through hole (121a) The part that forms this hinge joint,
The third coupling protrusion (133b) and the third coupling through hole (123a) are hinged to form a fixed rotation axis, and the second coupling protrusion (133a) and the second coupling through hole (132b) are hinged. The part that makes up is makes the non-fixed axis of rotation,
The lower joint 133 is connected to a linear actuator capable of detecting an adjustment position, and is configured to adjust the irradiation angle through electronic control. An intelligent short-range spotlight system for pedestrian safety at a crosswalk at night.
