[0005] A stop lamp housing portion 5c of the lamp housing 5 shown in the cross section of FIG. 4 is provided with a light source bulb 2a of the stop lamp. Since the light beam emitted from the light source bulb 2a is adjusted to a functional color (red-orange) as a stop lamp, the entire area where the front lens 6 faces the stop lamp housing portion 5c is colored R (red in this example). ) Is formed. Further, an inner lens 8 composed of a prism lens is provided inside the front lens 6 in order to obtain a proper light distribution characteristic as a stop lamp. When the inner lens 8 is provided in this manner, the front lens 6 is called an outer lens in comparison with the inner lens 8. (Figure 2
(See (A)) The combination lamp 1 of this example has a stop lamp 2 in the upper half. As described above with reference to FIG. 4, the stop lamp 2 has the R-color transparent layer 6 a formed on the outer lens 4, so that the appearance when the stop lamp is not lit looks red (in this example, red). ). When spots are applied to a portion having a red appearance to facilitate understanding of the structural function, the front projection shape of the stop lamp 2 is covered with the spots. Further, based on design considerations, in the combination lamp of the present example, the R-color transparent layer 6b is formed so that the band-shaped portion also exhibits the R-color appearance along the outer peripheral portion. The R-color transparent layer 6b has a frame-like band shape in a front view, and its cross section is shown in FIG.

[0004]

As described with reference to FIGS. 2A, 3 and 4, in the conventional combination lamp 1, (a) the prism corresponding to the area corresponding to the stop lamp 2 is provided. An inner lens 8 is provided, and (b) an R-color transparent layer 6a is formed on the outer lens 6 corresponding to the above area.
A band-shaped R-color transparent layer 6 is formed around an area where the outer lens 6 faces the turn signal lamp 3 and the back lamp 4.

However, a band-shaped R-color transparent portion 6b is formed on the outer peripheral portion. Therefore, as shown in FIG. 2B, the following three parts are formed in appearance.

[0005] α. An R color tone, a portion having a prism pattern, and β. A portion having an R color tone and no prism pattern; γ. A portion that has a W color tone and has no prism pattern. When a portion of 3 marks is formed like the above α, β, γ,
It is not preferable because it gives a complicated design feeling. Therefore, as shown in FIG. 2C, it is desired to form a simple and clear appearance in which the R color portion has a prism pattern and the W color portion has no prism pattern. This figure 2
In order to obtain the appearance as shown in (C), an inner lens with a prism having the same shape and the same size as the R color prism portion 10 shown in FIG. It is considered good. FIG. 5 shows an improved appearance of the combination lamp shown in FIG.
FIGS. 3A and 3B show a virtual inner lens which is considered necessary for obtaining the appearance as shown in FIG. 3C, wherein FIG. 3A is a front external view, and FIG. However, when the inner lens 11 as shown in FIG. 5 is to be injection-molded with a synthetic resin material, the rigidity is insufficient due to the narrow width dimension a of the frame-shaped portion, and there is a difficulty in molding technology. Can not. The present invention has been made in view of the above-described circumstances, and does not use an inner lens having a thin frame-shaped portion that involves modeling difficulties, and uses a prism on a band-shaped portion along the peripheral portion of the outer lens. An object of the present invention is to provide a vehicular lamp capable of displaying a pattern.

[0006]

In order to achieve the above object (presenting a prism pattern around the lens), a vehicle lamp according to the present invention comprises an outer lens and an inner lens having a smaller area than the outer lens. And a portion in which the outer lens faces the inner lens, and a band-like portion along the outer periphery of the outer lens are formed into one color tone R, and the color tone of the outer lens is formed. In a vehicular lamp configured to have a different color tone W from the portion other than the portion R, the outer lens is mounted on a lamp housing, a prism is formed on the inner lens, and the lamp housing is an outer lamp. A prism shape similar to or similar to the above prism is formed in the area facing the strip along the outer circumference of the lens. Wherein the but has been formed. When the color tone R in the above configuration is red and the color tone W is colorless or white, the practical value is large.
When carrying out the present invention, the above-mentioned color tone R and color tone W can be set arbitrarily, and selection of the color tone is not limited. However, the R color tone and the W color tone may be of the same system but may not be the same color tone.

[0007]

According to the above-mentioned means, since the prism is formed in the area of the lamp housing facing and separated from the strip along the outer periphery of the outer lens, when the vehicle lamp is turned off, the outer lens is turned off. A prism pattern appears on the appearance around. In this way, the prism pattern can be displayed without depending on the inner lens. In addition, since the prism shape of the lamp housing is similar or similar to the prism shape of the inner lens, when it appears in the appearance, the prism pattern derived from the inner lens and the prism pattern derived from the lamp housing are fused and different. Does not cause harmony. The prism pattern shown in the appearance of the vehicle lamp according to the present invention appears through the outer lens, but is derived from the prism shape independent of the outer lens, so the R color transparent layer applied to the outer lens is It can be set to any area. Therefore, it is possible to dispose the R color transparent layer completely in conformity with the prism pattern.
Since a color transparent layer can be provided, the design of the vehicle lamp can be improved and the design can be diversified.

Reference numeral 12 denotes a lamp housing to which the present invention is applied. The lamp housing 12 has a turn signal lamp housing portion 12a and a back lamp housing portion 12b having shapes similar to those of the conventional example. Further, prism-shaped portions 12c and 12d are formed at a portion where the turn signal lamp housing portion 12b faces the peripheral portion of the outer lens 6. The outer lens 6 is a member similar to or similar to that in the conventional example, and has a band-like R shape along the periphery as described with reference to FIG.
A color transparent layer (a red transparent layer in this example) 6b is formed. Therefore, the prism-shaped portions 12c and 12d formed by applying the present invention are disposed opposite to and separated from the R-color transparent portion 6b. In FIG. 1, the R-color transparent layer 6b is
Part of that cross section appears in the drawing. Then, a cross section of the prism-shaped portion 12c appears facing and separated from the portion of the R-color transparent layer 6b shown in the drawing. Prism shape part 12
1D is formed along the periphery of the turn signal lamp housing portion 12a of the lamp housing 5, and FIG.
Is not located on the cut surface, so the outline is drawn instead of the cross section. The prism-shaped portions 12c and 12d
Is an opaque component because it is integrally formed with a part of the lamp housing 12 made of an opaque material. Therefore, it is not a prism having a function of refracting a passing light beam, but a component having the same or similar appearance as the prism. The prism-shaped portion 12c of this example,
12d is formed of a synthetic resin material and has an aluminum reflective film deposited thereon. When the vehicular lamp of the embodiment shown in FIG. 1 is viewed in the direction of arrow b, the prism-shaped portion 12c is visually recognized through the R-color transparent layer 6b. The appearance at this time is similar to the case where the prism surface of the inner lens 8 is seen through the transparent transparent layer 6a as indicated by arrows c and c 'shown in FIG. Is felt. In the present embodiment, as described above, the same prism pattern as that of the inner lens 8 can be shown in the non-lighting appearance of the strip-shaped R-color transparent layer 6 a provided around the outer lens 6. it can.

According to the present invention, since the prism is formed in an area of the lamp housing which is opposed to and separated from the belt-like portion along the outer periphery of the outer lens, when the vehicle lamp is turned off, A prism pattern appears on the appearance around the outer lens. In this way, the prism pattern can be displayed without depending on the inner lens. In addition, since the prism shape of the lamp housing is similar or similar to the prism shape of the inner lens, when it appears in the appearance, the prism pattern derived from the inner lens and the prism pattern derived from the lamp housing are fused and different. Does not cause harmony. The prism pattern shown in the appearance of the vehicle lamp according to the present invention appears through the outer lens, but is derived from the prism shape independent of the outer lens, so the R color transparent layer applied to the outer lens is It can be set to any area. Therefore, R
It is also possible to arrange a color transparent layer, and it is also possible to arrange an R color transparent layer in harmony with the prism pattern, thereby improving the design of the vehicle lamp and diversifying the design. It has excellent practical effects.
