As shown in the figure, when a pedestrian or a vehicle crosses the road, the laser sensor 12 firstly senses that the pedestrian 60 passes through, and then sends a signal to the controller to enable the linear laser 11 to emit laser, the laser is projected to the position which is higher than the zebra crossing by 30cm, when the pedestrian 60 passes through, due to the fact that the laser is projected at the two ends, drivers in two directions are far away to see that the leg of the pedestrian 60 or the contour of the vehicle is projected to be red and moves across the road, and the drivers are reminded to decelerate to protect the pedestrian 60. Especially, the driver of the pedestrian 60 crossing direction is more obvious, and the driver of the other direction can see it, so that the driver of the other direction can be warned in advance.

Thus, in the pedestrian protection laser apparatus 100, the laser pile 10 is provided with the plurality of linear lasers 11, and at least the upper portion of the lasers 11 is provided such that the laser light emitted from the lasers 11 is further reduced. For example, a structure with a certain depression angle or other light-adjusting angle is adopted, so that the emitted light is farther and lower, that is, the emitted light is not parallel to the ground or upward inclined, but downwards depressed, so that in a short distance range, that is, the length range of the sidewalk, the upper part laser height is still higher than the lower part, and a plurality of laser warning lines 61 from bottom to top are formed, and the farther (without body obstruction) laser lines emitted from the upper part laser 11 are farther and lower, so that the laser is effectively prevented from being emitted to human eyes when the laser is farther, especially to human eyes with shorter heads of children.
