Refraction structure of decorative luminous pattern for automobile

The utility model relates to a refraction structure of a decorative luminous pattern for an automobile, which comprises a dash board which is provided with a specific font or graphic perforation and a light permeating board. Besides the protruding font which can penetrate through and be exposed at the surface of the dash board because of the protruding surface corresponding to the perforation, the bottom of the light permeating board is provided with a sloping light receiving surface at the range of corresponding to the protruding font. The surface of the light receiving surface is designed into a rough carving surface. The utility model also comprises a light emitting diode integrating board and a sealing cover. The sealing cover is provided with a bottom board in the same shape with the light permeating board and with a slightly larger area than that of the light permeating board. The utility model uses a miniature light emitting diode body as a light source to project the light source at one side of a long-rectangular thin light guide board. A light receiving surface at the bottom of a light guide material board body can refract the light source, and light can be respectively refracted out from each separate protruding font at the surface of the light permeating board so as to generate uniform pattern luster in flat space. The refraction structure of a decorative luminous pattern for an automobile can be used as a decorative light source and is applied to decoration or labeling at the inner part or the outer part of the automobile.
