Description of the Invention: The present invention relates to a license plate light source shielding structure for a tail light device, and more particularly to a license plate light source shielding structure for a taillight device for a locomotive. [Prior Art] The taillight device of the conventional general locomotive, as shown in Fig. 9, the taillight device 9〇6' shown in Japanese Patent Laid-Open No. 2_23 7880, which mainly includes a bulb 9〇9 and a lamp housing 908 covering the bulb 909, and the bulb 909 can be used. The light source 908 which emits white light and doubles as a tail light and illuminates the license plate number plate 905 is made of a light-transparent red fortified resin, and another colorless transparent license plate is attached to the lower side of the lamp housing 908. Lens 92 1. In addition, two bulbs are separately designed as the tail light source and the license plate light source. Since such a tail light device is composed of a white light bulb and a red lamp housing as a tail light, in order to obtain higher brightness, not only a larger size bulb but also a sufficient gap between the bulb and the lamp housing must be maintained, so that the tail light device is entirely The thickness is not easily reduced, and the problem that the display effect is poor is likely to occur after the bulb or the lamp is deteriorated. Therefore, more and more locomotives today use a red light-emitting diode with a transparent lamp housing as a tail light device, and a white light bulb is additionally provided for illuminating the license plate number plate. The tail light device TLi shown in FIG. 10 has a tail light composed of a plurality of red light-emitting diodes D· arranged on the circuit board pc, and a double light source composed of a white light bulb B, and is matched with a transparent press. The lamp housing 73 made of a resin is used to constitute the tail light device TL'. The above-mentioned conventional tail light device 9〇6 is made of a red-acrylic resin having light transmissivity because its lamp housing 9〇8 is made of a double-light source structure, and in which the light source of the license plate lamp is diffused to the lamp housing of the tail lamp, Since the lamp housing 908 of the taillight 128832.doc 1343885 is red, it still presents red light to the viewer. However, as shown in FIG. 10 (a), the tail light device tl having a dual light source, since the lamp housing 730 is made of a transparent material and the light emitting diode D is formed, the tail light source is red light and the license plate light is The bulb B and the light source are white light. Therefore, <<>> shall be provided with a partition 726 for separating the license plate light source from the tail light source to prevent the red tail light source from being interfered by the white license plate light source. However, yes, since the lamp housing 730 is made of transparent acrylic resin and has a certain thickness of meat thickness as shown in the schematic diagram of HlG(b), the light of the license plate light source obliquely enters the transparent lamp housing 730 meat. In the thick interior, since the transparent lamp housing 730 and the air to the light δ are two media of different refractive indices, the light obliquely entering the transparent lamp housing 730 is partially refracted at the interface of the two media, and the rest is Reflected. However, when the angle of incidence of the light (the angle between the light and the normal of the vertical medium interface) is larger than the critical angle, the light will stop entering the other interface (air), and vice versa, all of the inner surface, that is, the lamp shell 73 is thick. Internal reflection, and continuous total reflection at the junction of the thick surface and the air, and spread forward along the zigzag. As a result, as shown in Fig. 10(c), at the end portion of the transparent lamp housing 730, white light is emitted at the end points τ, τ, which interferes with the red tail light source. On the other hand, in order to prevent dust from being generated by friction between the lamp housing 730 and the partition portion 726 due to vibration when the vehicle is traveling, it is generally structurally designed to maintain a gap C therebetween. However, as a result, the license plate light source will diffuse through the gap C to the tail light and drop. The low partition 726 spatially blocks the effect of the license plate light source from interfering with the tail light source. SUMMARY OF THE INVENTION 128832.doc 1343885 The problem that the tail light source is interfered by the license plate light source in the tail light device of the conventional locomotive has been known for a long time.

In the embodiment of the present invention, the position of the light blocking member R is matched with the position of the opening periphery of the license plate lamp cover portion 28, as shown in FIG. 5(b), and is attached to the above-mentioned opaque paint. The band-shaped peripheral edge p, for example, may be composed of two upper and lower portions. However, the attachment of the light blocking member r to the strip-shaped peripheral edge P is not a condition necessary for the present invention, and the position at which the light blocking member R is attached is mainly determined depending on the position of the peripheral edge of the opening of the license plate lamp covering portion 28. The number of the light-blocking cows is not limited to two, and is mainly determined according to the shape of the opening of the license plate cover portion 28. In addition, in the embodiment of the present invention, the If light in the light-transmitting portion 36 of the license plate lamp and the body of the lamp housing 30 can be formed by laser engraving on the periphery of the light-transmitting portion of the license plate lamp as shown in FIG. 7 . Continuous fine point l. Since the continuous fine point portion 1 forms an obstacle for the light transmission along the flesh thickness, the light source of the H package B can be further reduced to be transmitted to the tail light along the thickness of the lamp housing 3 G, thereby further improving the tail light source from being interfered by the license plate light source. phenomenon. On the other hand, in the case where the license plate lamp light transmitting portion 36 and the lamp housing 3 are formed separately, as shown in FIG. 8, the license plate lamp light transmitting portion 36 can be welded and fixed to the lamp by means of ultrasonic welding. The body of the shell 30. Ultrasonic welding is the application of high-frequency vibration to the workpiece of the thermoplastic part. This kind of vibration causes the friction between the molecules to increase the temperature of the joint surface of the workpiece. When the temperature is high enough to melt the plastic, the material on the joint surface of the workpiece will be There is flow, and it solidifies after the vibration stops to complete the splicing. In the embodiment of the present invention, the joint surface of the license plate lamp light transmitting portion 36 and the lamp housing 3 〇本赵 is solidified by the instantaneous high temperature melting when the ultrasonic wave is welded, so that the surface flatness of the joint surface is deteriorated. For the light transmitted along the thickness of the meat, this deteriorated surface flatness will also form an obstacle to the transmission of light. Therefore, this configuration can further reduce the light source of the license plate light bulb B along the lamp shell. At the end of the lamp, the taillight green is further improved by the light source of the license plate. Further, the license plate light transmitting portion 36 is usually limited to the illuminance requirement and must be a specific color, such as colorless and transparent. In the present embodiment, the light-transmitting lamp housing 30 can be selected from the light-transmitting portion of the license plate lamp by the light-transmitting portion 36 of the license plate lamp and the lamp housing 30. . The technical and technical features of the present invention are disclosed above, but those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the present invention is not limited by the scope of the invention, and the invention is intended to cover various alternatives and modifications.
