Description

[Detailed Description of the Invention] [Industrial field of application] In a lamp in which a lens mounted on the front surface of a lamp body extends beyond the lamp body, and this lens extension is a dummy area, a reinforcing plate is provided in the dummy area. Is attached to secure the strength of the dummy area. As described above, the present invention relates to a vehicular lamp in which another member such as a reinforcing plate is attached to the back side of the lens extending portion forming the dummy area.

[Prior art]

In this type of lamp, as shown in FIG. 10, a part 2 of the front lens assembled in the front opening of a lamp body (not shown) extends beyond the lamp body to form a dummy area. A reinforcing plate 6 is provided on the back side of the lens extension portion 2 to be formed.
Is attached by adhesion or heat fusion, and the lens extension 2
To ensure the strength of. As shown in FIG. 11, the engaging portion between the reinforcing plate 6 and the lens extending portion 2 is formed by notching the inside of the peripheral frame 3 of the lens extending portion 2 to form a step portion 4. The end portion 6a of the reinforcing plate is engaged with the structure. Reference numeral 8 in FIG. 10 is an end rubber adhered to the end of the lens peripheral frame 3 so as to come into contact with the lamp mounting surface (not shown) of the vehicle body.

[Problems to be solved by the invention]

However, in the above-mentioned conventional technique, since the step portion 4 is formed on the lens peripheral frame 3 to which the reinforcing plate 6 is attached, as shown in FIGS. 11 and 12, the lens peripheral frame in the step portion forming region is formed. 3 has a depth d _{1 that} is greater than the depth d ₂ of the lens peripheral frame 3 in the step-unformed region.
The depth is shorter by d ₃ (d ₂ = d ₁ + d ₃ ). In order to make the lens extension 2 a dummy area, the back surface of the lens extension 2 is coated with a reflective film, but the area where the reflective film is formed is a fisheye step 2a. The lens peripheral frame end surface is limited to the lens peripheral frame inner surface 2b continuous with the formed design surface area and the design surface area 2a.
No reflective coating is applied to the inner surface 2d of the step 2c or the stepped portion 4.

For this reason, comparing the hues of the step forming area and the step non-forming area of the lens peripheral frame 3 when viewed from the front of the lamp, the optical path length d ₁ and the optical path length d ₂ in the lens peripheral frame 3 are different (d ₁
<D ₂ ) Therefore, the degree to which the background color of the lens peripheral frame 3 is affected is different, and the step portion forming area and the step portion non-forming area appear to have different hues, and there is a problem that the lighting of the lighting device is not so good. It was

The present invention has been made in view of the above-mentioned problems of the prior art,
It is an object of the present invention to provide a vehicular lamp that has a good appearance in a peripheral frame of a lens extending portion which is a dummy area of a lens extending beyond a lamp body.

[Means for Solving the Problems]

In order to achieve the above object, in the vehicular lamp according to the present invention, a part of the front lens assembled to the front opening of the lamp body is extended to the outside of the lamp body. The inner surface of the extension part excluding the end face of the peripheral frame is coated with a reflective film to make this lens extension part a dummy area, and a part of the peripheral frame of the lens extension part is cut out, and the reinforcing plate is formed in this cutout part. A vehicle lamp in which another member such as the above is engaged and attached, and an end rubber having a dark color is interposed between the vehicle body and the peripheral edge frame of the lens extending portion, and at least the notch of the other member. The color of the engaging part area with the part,
This is a dark color system that is sufficient to eliminate the color difference visible through the notch formation region and the notch formation region of the lens extension peripheral frame.

[Action]

Since the depth of the lens peripheral frame is larger in the notch forming region than in the notch forming region, the optical path length in the lens peripheral frame is long, and the dark color of the end rubber or the like strongly strengthens the ground color of the lens peripheral frame. The color will be tinged. On the other hand, in the cutout formation region, the depth of the lens peripheral frame is smaller than that in the cutout non-formation region, so the optical path length in the lens peripheral frame is short, and the ground color hue of the lens peripheral frame is smaller than that in the cutout nonformation region. Although not strongly tinged, it is a tint of the background color of the lens peripheral frame to the dark color of the reinforcing plate, which is almost the same as the tint-free region.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 9 show an embodiment of the present invention, and FIG. 1 is a perspective view of a tail and stop lamp viewed from the back side,
2 is a plan view of the tail and stop lamp, FIG. 3 is a sectional view taken along line III-III shown in FIG. 2, and FIG. 4 is a sectional view taken along line IV-IV shown in FIG. The figure is line V shown in FIG.
-V is a sectional view, FIG. 6 is a sectional view taken along line VI-VI shown in FIG. 2, FIG. 7 is an enlarged sectional view showing a part of FIG. 5, and FIG. 8 is FIG. Sectional drawing which expands and shows a part of FIG.
The figure is a perspective view showing a part of the reinforcing plate.

In these figures, reference numeral 10 is a tail and stop lamp, which is a container-shaped lamp body in which a bulb 12 is mounted.
The front lens 16 is assembled to 14 and integrated as a lamp. The inner peripheral surface of the lamp body 14 is formed into a parabolic shape, and a reflective film coating is applied to the reflector 13 to form the light, and the light from the bulb 12 is guided forward as parallel light. . Further, a horizontal flange portion 15 having a predetermined width is formed in the front opening portion of the lamp body 14 so as to surround the opening portion, and a front lens 16 having a fisheye step is fixed to the flange portion 15 with an adhesive. Has been done.

The front lens 16 is opposed to the front opening of the lamp body, and a red lens region 17 that guides bulb light to emit light.
The lens area 17 is surrounded by the lens body 14, and the amber-colored lens extension portion 18 extending in the left direction in FIG. The back surface 18a of the design surface area of the lens extension 18 excluding the red lens area 17 and the inner side 20a of the lens peripheral frame 20 which stands up substantially orthogonally from the design surface area of the lens 16 are coated with a silver reflective film. When the lamp is viewed from the front, the dummy area in which the silver color of the reflection film and the amber color (yellow) which is the background color of the lens extension 18 are integrally formed is seen in a golden hue.

On the back side of the extension 18, a reinforcing plate 3 made of ABS material is used.
0 is installed. A stud bolt 52 and a fastener 54 are provided on the back side of the reinforcing plate 30, and a fastener 56 is provided on the back side of the flange portion 15 of the lamp body 14.
In cooperation with, the lamp 10 is mounted on the vehicle body 60 (see FIGS. 3 and 4).
It can be attached and fixed to. Reference numeral 58 is a sponge material provided on the back surface of the horizontal flange portion 15 of the lamp body 14.

The peripheral edge frame 20 of the lens extension portion 18 has a step portion that vertically opposes.
22 is formed, and the side edge portion 31 of the reinforcing plate 30 is engaged with the step portion 22 and is fixed by heat fusion. Further, a black end rubber 40 is attached to the frame end surface 21 of the lens peripheral frame 20 with an adhesive,
When the 10 is attached to the vehicle body, the vehicle body 60 and the peripheral edge frame 20 of the lamp are in pressure contact with each other so that the play between the lamp 10 and the vehicle body 60 is eliminated.

The reinforcing plate 30 is an opaque light brown color. Since the frame end surface 21 of the lens peripheral frame 20 and the inner surface of the step portion 22 of the peripheral frame are not coated with a reflective film that is applied to the back side of the lens extension portion 18, the lens peripheral edge is seen from the front of the lamp 10. Looking at the frame 20, the end rubber is
In the step forming region 40, the reinforcing plate side edge 31 is visible through the lens peripheral frame 20. And step 22
The area in which the end rubber 40 is not formed looks brown, which is a mixture of the black background color of the end rubber 40 and the amber background color of the lens peripheral frame 20. On the other hand, the area in which the step portion 22 is formed looks brown, which is a mixture of the light brown that is the ground color of the reinforcing plate 30 and the amber color that is the ground color of the lens peripheral frame 20. That is, in the stepped portion non-formation area, the light that has entered the lens peripheral frame 20 from the outside is transmitted through the lens peripheral frame 20 as shown by reference numeral l ₁ → l ₂ in FIG.
The light is reflected on the back surface of 40, passes through the lens peripheral frame 20 again, and reaches the eyes of the viewer. Further, in the step portion forming region, as shown by reference numeral l ₃ → l ₄ in FIG. 8, the lens peripheral frame 20 is transmitted, the end surface of the reinforcing plate 30 is reflected, and the lens peripheral frame 20 is transmitted again. Then it reaches the eyes of the viewer. Comparing the optical path lengths d ₁ and d ₂ in the step forming area and the non-forming area, the depth d ₁ of the lens peripheral frame 20 in the step forming area is larger than that in the step non-forming area. Since the depth is shorter by d ₃ , that is, the optical path length in the lens peripheral frame 20 is shorter (d ₁ <d ₂ ), the influence of the amber color (yellow) which is the ground color of the lens peripheral frame 20 is small. In other words, the degree of the amber color of the light l ₄ is smaller than the degree of the amber color of the light l ₂ . In consideration of this point, the color of the reinforcing plate 30 is set to be a light brown color, and it is devised so that the same hue as that in the step portion non-formation region is generated.

Then, in the step forming area of the lens peripheral frame 20 in the dummy area, the light brown color of the reinforcing plate 30 becomes a light yellow color of the lens peripheral frame 20 and becomes brown, and in the step non-forming area, the black color of the end rubber 40 is the lens peripheral edge. The frame 20 turns yellow and becomes brown. Both areas appear to be the same continuous brown color, and there is no inconvenience that only the stepped portion forming area looks different from the other areas (stepped portion non-formed area) as in the conventional case.

Further, the reinforcing plate 30 has a diamond-shaped recess 32 on both front and back surfaces.
Are arranged in a houndstooth check pattern. This type of conventional reinforcing plate has a structure in which ribs in the shape of an orthogonal lattice are formed on one surface of the plate, and there is a tendency for the rib forming side to warp so that the rib forming side is on the outside due to heat shrinkage during molding. There was a problem that it could not be assembled smoothly and integrated because it floated when it was attached to. However, since the reinforcing plate 30 has a structure in which substantially similar diamond-shaped recesses 32 are formed on both front and back surfaces, the problem of warping on one side during molding is solved.

In the above embodiment, the entire reinforcing plate 30 is light brown so as to eliminate the difference in hue between the step forming region and the non-forming region, but the engaging part region of the reinforcing plate 30 that engages with the step 22 You may make it light brown only.

Further, in the above-described embodiment, the case where the peripheral frame 20 of the lens extension portion is amber and the end rubber 40 is black is described, but the lens peripheral frame 20 is another color (for example, red) and the end rubber 40 is also For other colors, the reinforcing plate 30 may be a dark color that eliminates the difference in color due to the difference d ₃ between the optical path lengths d ₁ and d ₂ in the lens peripheral frame 20.

[Effect of device]

As is apparent from the above description, according to the vehicular lamp of the present invention, the difference in color due to the difference in the optical path length between the notch forming region and the notch not forming region of the lens peripheral frame is determined by the dark color system of the reinforcing plate. By adjusting the color of the notch formation area and the notch formation area to be approximately the same, the appearance of the peripheral frame of the lens extension part that constitutes the dummy area will be good and The appearance is also good.
