For example, there are four rectangular black dotted-line frames in the center of the car sign in Fig. 13, these four black dotted-line frames are the light areas of the car lights, and four light path conducting devices of the car lights of the present utility model can be used to To construct this bright area, the shape of the lamp lens 5b of each light path conduction device or the light-receiving area 9 on the lamp lens 5b is the same as the area of a black dotted line frame in Figure 13, and the light emitted from the lamp lens 5b makes the The area enclosed by the dashed black box in 13 is illuminated. Also can be like in Fig. 14, need to use the light path conduction device of four car lamps of the present invention to construct this light area, the shape of the car lamp lens 5b of each light path conduction device or the light-receiving area 9 on the car lamp lens 5b It only needs to be the same as the area of a black dotted line frame in FIG. 14 , and the light emitted from the lamp lens 5 b makes the area in the black dotted line frame in FIG. 13 emit light. Figures 15 to 20 show different configurations of the bright areas on the car label. For these constructions, only the same number of light path conducting devices as the black dotted frame on the car label is required. According to the car label in Figures 15 to 20 The shape of the lamp lens 5b of the corresponding light path conduction device or the light-receiving area 9 on the lamp lens 5b of the corresponding light path conduction device is set in the black line frame area on in bright areas.
