Traffic light device based on laser radar

The invention discloses a traffic light device based on a laser radar, and belongs to the field of traffic equipment. The device comprises a pillar, an indicating device and a laser radar integrated board, wherien the upper end of the pillar is fixedly connected with the bottom of the indicating device in an embedded mode, the laser radar integrated board is fixedly installed above the indicating device, and the indicating device is provided with a frame, a circuit board and an indicating lamp. A heat block expands when being heated, so that a tough block wriggles, and then, a rotating force is generated; the outer side of the tough block abuts against the outer end of a power-on frame to rotate, so that the whole abutting ball can softly rotate, and the abutting ball can drive the moving plate to move along with the abutting ball; the position of the whole moving body is continuously changed behind the signal lamp, and hot air flow can be driven to move; and lateral heavy pressure of the rolling ball on the
