Problems solved by technology
[0004] It can be seen that the traditional film film is easily affected by factors such as light radiation, humidity, temperature, etc., resulting in poor corrosion resistance, weather resistance, and easy damage.
Moreover, the currently used films generally have light transmission, and the image quality needs to be improved.

Abstract
The invention discloses a film, a production method thereof and a projection lamp. The film production method includes the steps: preparing glass substrates; producing shading coatings on the glass substrates; processing the shading coatings to form patterns on the shading coatings to obtain semi-finished products; cutting the semi-finished products. The method avoids a traditional mode that the patterns are formed by the aid of silver halide photosensitive materials, gelatin and the like, stable black coating can be selected according to actual requirements, so that the film has good corrosion resistance, weather resistance and stability, is easy to store and can be used for a long time, the service lives of projection films are prolonged, troubles of users regularly replacing the projection films are avoided, and user experience is improved. According to the method, projection patterns are produced by the aid of the shading coatings, areas without patterns on the film are lightproof, imaging clearness of the projection lamp is ensured, and visual effects are improved.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for making a film, a film and a projection lamp. Background technique [0002] With the improvement of people's living standards, people's requirements for car personalization are getting higher and higher, and the use of lights to achieve colorful projections is one of these many personalized needs. The projection lamp is a light source that collects light beams shaped by the light beam on the film sheet with a pattern. The pattern of the film sheet is enlarged and projected to produce a pattern effect through the imaging projection lens group. The projection has a high appearance and ornamental value. The film sheet can be made into various pattern effect. [0003] The traditionally used film negative is a film film coated with silver halide photosensitive material and gelatin. Gelatin has water-absorbing properties. In a humid environment, the water-absorbing pro...
