[0002] With the development of projection lamp technology, projection lamps are increasingly used in cars. The projection lamps on cars are used to welcome VIPs, and the effect of projection lamps is particularly obvious when it is dark or at night.

[0003] With regard to the existing patent number: CN201820366543.9, patent name: automobile rearview mirror projection lamp, it adopts the method of clamping the film by the first pressing part of the first convex lens in the focusing module and the second pressing part of the second convex lens in the imaging module, so that the film is fixed between the focusing module and the imaging module, and through the limiting and positioning cooperation of the second positioning column, the hollow positioning part and the second positioning hole, the first convex lens, the film and the second convex lens are fixedly connected, thereby improving the stability and accuracy of the connection between the three, and solving the problem that the modules of the existing projection lamp are separated and arranged at intervals. Once a module is offset, the imaging quality is low. However, when it is installed on the rearview mirror, it is difficult to install it on rearview mirrors of different models, and the projection angle of the projection lamp cannot be adjusted.

[0004] The existing projection lamp for automobile rearview mirror is difficult to be installed on automobile rearview mirrors of different models, and it is difficult to adjust the angle of the projection lamp; therefore, it does not meet the existing needs. In this regard, we propose a projection lamp for automobile rearview mirror. Utility Model Content
