The invention discloses a street lamp capable of adjusting the mounting height and angle of a lamp holder according to the environment, and relates to the technical field of lighting equipment. The street lamp comprises a base, a lamp post, a sliding rail, a
linear motor, a sliding block, a mounting plate, an angle adjusting mechanism, a connecting rod and an illuminating lamp, the base is of a cavity structure, and the lamp post is vertically installed on the base. The bottom of the lamp post is welded to the base, the sliding rail is vertically arranged on the side wall of the lamp post, thelinear motor and the sliding block are connected to the sliding rail in a matched mode, the
linear motor is fixedly connected with the sliding block, the mounting plate is fixedly connected to one side of the sliding block, the angle adjusting mechanism is arranged in the mounting plate, and one side of the angle adjusting mechanism is fixedly connected with the lighting lamp through the connecting rod. The sliding block is driven by the
linear motor to slide on the sliding rail, so that the lighting lamp can slide from the high position of the lamp post to the low position of the lamp post,and maintenance and adjustment of the
irradiation height of a lamp cap are facilitated; the
illumination angle of the illumination lamp can be adjusted through the angle adjusting mechanism, and the illumination range of the lamp holder of the street lamp can be adjusted conveniently according to different environment requirements.
