Description

Preparation method of patterned lamp film, patterned lamp film and lamp Technical Field The invention relates to the technical field of lighting lamps, in particular to a preparation method of a patterned lamp film, the patterned lamp film and a lamp. Background With the continuous improvement of modern life and aesthetic level, consumers put higher demands on the lamp decorative film in visual effect, durability and the like. The method for preparing the lamp decorative film in the current market comprises the following steps of (1) directly forming decorative patterns by adopting an internal colored drawing process, wherein the method is visual in operation, but when the lamp is applied to an outdoor environment, pigment chalking, fading and even integral peeling are extremely easy to occur due to long-term ultraviolet irradiation, temperature change and humidity erosion, and the appearance quality and the service life of a product are seriously influenced. (2) The pattern is manufactured by adopting a process of spraying paint and then laser etching, although the pattern can be formed in the mode, the control requirements on the uniformity of a base material, the thickness of a paint layer and laser parameters are very strict, the investment of laser etching equipment is large, the processing efficiency is limited, and the whole manufacturing cost is high. In view of the above, the method for preparing the decorative film of the lamp in the prior art has the disadvantages of poor outdoor durability and high cost, and a new method for preparing the decorative film is needed to solve the above problems.
