[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-8 As shown, the utility model provides a technical solution: a car license plate projection lamp, comprising a shell 1, a bracket 2 and a lampshade 3 arranged in a mounting groove 14 of a car body 13 above a car license plate 12, the shell 1 is a plastic shell or a metal shell, the plastic shell is lighter, and the metal shell has better heat dissipation, which can be freely selected according to the use scene of the car, the bracket 2 is fixedly installed on the lampshade 3, a lighting projection integrated chip 4 is installed on the bracket 2, a projection lens 5, a lamp bead 6 and a processor 7 are arranged on the lighting projection integrated chip 4, the projection lens 5 is used to project an image, and the lamp bead 6 is a white LED light source for license plate lighting;

[0031] The bracket 2 is movably connected to the housing 1, and a claw 10 is provided on the bracket 2. The bracket 2 and the claw 10 are an integrated structure, which is convenient for manufacturing and assembly. The bracket 2 is movably hinged to the housing 1 through the claw 10, and an angle adjustment mechanism 8 is installed between the housing 1 and the bracket 2. The angle adjustment mechanism 8 is a linear stepping motor, and the screw pair of the linear stepping motor is movably hinged to the bracket 2 through a movable shaft 11 on the bracket 2. The movable shaft 11 and the angle adjustment mechanism 8 are arranged at the position of the bisector of the length of the bracket 2, and are arranged in the center, with balanced force, which improves the service life. The distance of low-angle projection is short and the image is small, and the distance of high-angle projection is far and the image is large, which is used to realize projection angle adjustment;

[0032] There are two groups of projection lenses 5 and lamp beads 6. The two groups of projection lenses 5 and lamp beads 6 are symmetrically arranged above the license plate 12, symmetrically dispersed, and preferably arranged near the taillights on each side along the width direction; compared with the single projection just above the license plate, the projection model is more three-dimensional and suitable for adjustment, the distance range of the two symmetrical projections is larger, and the dynamic and static projection effects are better. The shape and size of the lampshade 3 are adapted to the mounting groove 14, and the length and width of the housing 1 and the bracket 2 are smaller than the length and width of the mounting groove 14, so the installation is firm and the angle adjustment is convenient;
