Method for manufacturing colored pattern sheet of projection lamp

Abstract

The invention discloses a method for manufacturing a colored pattern sheet of a projection lamp. The method comprises the following steps: step 1, decomposing a colored pattern into four basic colors of C, M, Y and K by using a picture processing tool, and converting the four basic colors into a gray pattern; step 2, carving the gray pattern pixel points of the four basic colors C, M, Y and K in the step 1 on corresponding C-color pigment-plated film glass sheet, M-color pigment-plated film glass sheet, Y-color pigment-plated film glass sheet and K-color pigment-plated film glass sheet by using laser equipment; respectively forming a C-color light-transmitting glass sheet, an M-color light-transmitting glass sheet, a Y-color light-transmitting glass sheet and a K-color light-transmitting glass sheet; and step 3, sequentially stacking and gluing the K-color light-transmitting glass sheet, the C-color light-transmitting glass sheet, the M-color light-transmitting glass sheet and the Y-color light-transmitting glass sheet in the step 2 from top to bottom so as to obtain a corresponding colored pattern sheet. The process is simple, resources are saved, and the manufactured pattern sheet is smooth in color transition connection and good in projection effect.

Description

technical field [0001] The invention relates to the technical field of pattern sheets, in particular to a method for manufacturing a color pattern sheet for a projection lamp. Background technique [0002] The traditional production of color gobos is made by superimposing and bonding multiple gobos of a single color. During the production process, a large number of gobos of a single color are required to complete, resulting in waste of resources. At the same time, some special colors can only be Choose similar color gobos to replace, often appear color difference phenomenon, and the color transition of the gobos is not smooth, and the color is strong. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages and deficiencies in the prior art, and provide a method for manufacturing a color pattern sheet of a projec...
