Abstract
The utility model relates to the technical field of intelligent traffic equipment and discloses a flash lamp. The flash lamp comprises a shell and a lamp tube mounted inside the shell. The flash lamp further comprises a convex lens which is slidably assembled on the shell and located in the light outgoing side of the flash lamp, and an adjusting mechanism which drives the convex lens to slide with respect to the shell to adjust the distance between the convex lens and the lamp tube, and is connected with the shell and the convex lens. When the lamp tube flashes, direct light emitted by the lamp tube irradiates the surface, facing towards the lamp tube, of the convex lens and forms a light compensating region after passing through the convex lens. As the adjusting mechanism can drive the convex lens to slide with respect to the shell to adjust the distance between the convex lens and the lamp tube, the distance between the convex lens and the lamp tube can be adjusted by the adjusting mechanism based on the needs of a road so as to enable the light g emitted by the lamp tube to fall upon different positions in the side, facing towards the lamp tube, of the convex lens, thereby adjusting the size of the light compensating region formed by the light emitted by the lamp tube after passing through the convex lens.
