Manufacturing method of color pattern imaging light-transmitting sheet for automobile projection lamp

Abstract

The invention discloses a manufacturing method of a color pattern imaging light-transmitting sheet for an automobile projection lamp. A plurality of same color pattern units are formed on a glass substrate, each color pattern unit consists of a plurality of color coating layers, according to the plurality of color coating layers, materials with different colors are orderly deposited on the surfaceof the glass substrate according to different colors, and finally the glass substrate is cut and separated by taking the color pattern units as units, so that each color pattern unit independently becomes a color pattern imaging light-transmitting sheet. Compared with a light-transmitting sheet manufactured through a traditional ink printing mode, the color pattern imaging light-transmitting sheet manufactured through the method has the advantage of being not prone to fading, projected characters or patterns are high in definition, and better quality performance is achieved.

Description

technical field [0001] The invention relates to a light-transmitting sheet element installed in an automobile projection lamp system, in particular to a method for manufacturing a color-pattern imaging light-transmitting sheet that can reduce color fading of the colored light-transmitting sheet and improve the performance of projected patterns. Background technique [0002] Based on the consideration of providing further visual sensory decoration, sense of honor or luxury of the car, some models of cars on the market are equipped with projection lights in specific parts to project patterns or text images on the ground when the projection lights are activated. Appropriate position on the vehicle or body. For example, a projection lamp can be installed at the car door, and when the door is opened, the projection lamp is automatically activated to project a pattern or text image on the ground, thereby highlighting the visual sensory effect at night or in a dark environment.

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the color of the color pattern imaging light-transmitting sheet used for automobile projection lamps is easy to fade, and the clarity of patterns and characters is low, which hinders the quality of the color patterns or characters projected by the projection lamp.
