【Example】

Next, embodiments of the present invention will be described based on the drawings. 1 to 4 show an embodiment of the present invention, and FIG. 1 is an embodiment of the present invention. Figure 2 is a front view of the tail & stop lamp, and Figure 2 is a longitudinal cross-sectional view of the lamp (line II shown in Figure 1). -II), Figure 3 is a front view of the lamp when it is lit, and Figure 4 is a non-point view. FIG. 3 is a front view showing the state of the lamp when it is lit.

0010 In these figures, the reference numeral 10 is a vertically long container-shaped lamp body. An outer lens 12 having a reddish color, which is a functional color, is attached to the front opening of the lens 10. A vertically elongated light chamber space is formed. At the bottom of this light chamber space is the lamp body. A bulb 14, which is a light source, is inserted into a bulb insertion hole 11 formed on the lower surface of 10. is accommodated. A Fresnel step 17 is formed in front of the valve 14. An inner lens 16 is arranged, and the direct light from the bulb 14 is transmitted through this inner lens. By passing through the lens 16, the light becomes parallel light and is guided to the outer lens 12. In the lower region of the outer lens 12, that is, the region corresponding to the inner lens 16, A fisheye step 13 is formed to diffuse light, and an inner lens 16 is formed. The emitted light is diffused and distributed over a wide range by passing through the outer lens 12. Ru. Reference numeral 12A in FIG. 3 indicates a region that emits light by the light emitted from the inner lens 16. show.

[0011] In addition, in the light room space, there are a plurality of horizontal plate-shaped branch light guide parts 24 (24a, 24b, 2 4c) in the vertical direction along the inside of the lamp body 10. It is arranged. That is, the stippled light guide member 20 has a lower edge 20a which is a light incident end. is placed facing the valve 14, and a flat plate with countless stipples 22 on the back side. A shaped light guide base material 21 and three flat plate-shaped branched light guides branched from this light guide base material 21. 24 (24a, 24b, 24c). The branch light guide section 24 is The horizontal branching light guide portions are formed to extend parallel to each other diagonally upward at a predetermined interval in the downward direction. The light emitting end surface 25 (25a, 25b, 25c) formed at the tip of the It is arranged close to the tar lens 12. Therefore, the light incident end of the light guide base material 21 The light from the bulb 14 that enters the 20a is reflected by the stippling 22 and reaches the front of the base material 21. The light is emitted toward the outer lens 12, causing the entire outer lens 12 to emit a faint light. In addition, inside the light guide base material 21 At this time, a part of the light whose traveling direction has been changed by the stipple 22 travels inside the branch light guide section 24. The light emitted from the light emitting end surface 25 of the outer lens 12 (25 The regions (horizontally long rectangular regions) corresponding to a to 25c) are caused to emit light. Figure 3 code 25A , 25B, 25C are the light emitting end surfaces 25 (25a to 25c) of the horizontal branch light guide section 24. The light from the bulb 14 is shown as a region that emits light by the light emitted from the bulb. The light flux density is smoothed by traveling through the light member 20, and the light emitting end face 25 Light with smoothed luminous flux density is emitted from the light emitting areas 25A~ 25C is formed.

0012 Further, on the lower surface of the branching light guide section 24, a light reflecting surface 26 (26a, 26a, 26b, 26c) are formed, and the bulbs of the branch light guide parts 24a, 24b are further formed. At a position corresponding to directly above 14, there is a transparent portion 27 which is not subjected to aluminum vapor deposition treatment. is formed. Therefore, the light from the bulb 14 is transmitted not only to the light reflecting surface 26a but also to the light reflecting surface 26a. The light is also guided through the transparent portion 27 to the reflective surfaces 26b, 26c, and the reflective surfaces 26a, 26 The light reflected by b and 26c causes the light to correspond to the light reflecting surface 26 of the outer lens 12. The area that is illuminated emits light. 3, symbols 26A, 26B, and 26C are light reflecting surfaces 26a to 26c. 26A and 26B show areas that emit light by reflected light in the area 26A and 26A. and 26B have transparent portions 2 on the light reflecting surfaces 26a and 26b that have little effect as reflecting surfaces. 7, the amount of light at the center is smaller than at the periphery, and the light emitting area is approximately rectangular. 26C, since the light reflecting surface 26c mainly reflects the light that has passed through the transparent part 27, the central part It has a generally rectangular shape in which the amount of light at the area is larger than that at the periphery. In addition, the fisheye of outer lens 12 The area where step 13 is not formed is frosted and the light emitting area is The so-called group eliminates the difference between the light-emitting part and the non-light-emitting part in areas 26A, 26B, and 26C. It has a radiation effect.

[0013] In this way, when the lamp is lit, the light emitting end surfaces of the horizontal branch light guide parts 24a to 24c Areas 25A to 25C corresponding to 25a to 25c emit light clearly in a horizontally long rectangular shape. Areas 26A to 26C sandwiched above and below the light emitting areas 25A to 25C emit faint light. Therefore, a novel lighting state of the lamp is formed in which the light emitting areas 25A to 25C have a horizontal striped pattern. be done.

Furthermore, when the lamp is not lit, the frost applied to the back side of the outer lens 12 prevents the interior of the lamp from being seen through, and furthermore, the light emitting end surfaces 25a to 25c close to the outer lens 12 are shown in FIG. As shown in 25A ₁ to 25C ₁ , the areas appear black compared to other areas, so a design is formed in which the areas 25A ₁ to 25C ₁ corresponding to the light emitting end faces (25a to 25c) that appear black have a horizontal striped pattern.

[0015] Figure 5 shows another embodiment of the present invention, which is a longitudinal sectional view of a tail and stop lamp. It shows. This second embodiment has a structure in which the lamps shown in the first embodiment are arranged upside down. The other parts are the same as the first lamp structure described above, and the same symbols are used. The explanation thereof will be omitted.

[0016] Note that in the two embodiments described above, the horizontal branching light guide section 24 has a structure in which three pieces are formed. However, by forming many more horizontally branched light guiding parts, a lighting pattern with multiple layers of horizontal stripes was created. It may also be formed.

[0017]

[Effect of the idea]

As is clear from the above explanation, according to the vehicle lamp according to the present invention, the dotted light guide The light emitted from the horizontal branch light guide part of the component creates a horizontal band-shaped light emitting part on the lens and the water The light reflected from the light reflecting surface formed on the flat branch light guide causes the light emitting part on the lens to A novel lamp lighting state with horizontal stripes arranged alternately downward is formed. Also conventional Compared to lamps, lenses have no light-blocking parts, so the entire lens emits light, improving visibility. In good condition.
