[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp in which a reflex reflector, which is a reflector for reflecting incident light in the same direction, is integrated with a part of an outer lens.

[0002]

2. Description of the Related Art A reflex reflector, which is a reflector, is provided at the rear of an automobile, but is generally provided integrally with a part of an outer lens of a rear lamp such as a tail-and-stop lamp. 5 and 6 are a front view and a sectional view of a main part of a conventional lamp of this type. A reflex reflector 4 composed of a group of reflecting prisms 5 is integrally provided on a part of an outer lens 2 having a fisheye step 3 formed thereon. On the back side of the reflex reflector 4, a sealing plate 6 for sealing the reflection surface of the reflex reflector is attached. If dirt or water drops that enter the lamp room adhere to the reflective surface of the reflex reflector,
Since dirt and water droplets can be seen through the outer lens 2 and the appearance is poor, and the light reflecting function as a reflex reflector may be impaired, conventionally, the reflection prism group 5 of the reflex reflector is fixed by a sealing plate 6 fixed by welding. To cover. Reference numeral 8 denotes a bulb as a light source.

[0003]

However, in a conventional lamp, when a plurality of reflex reflectors 4 are arranged in parallel as shown in FIGS. Since each has a structure covered by the sealing plate 6,
It is necessary to form the standing wall-like legs 2a surrounding the reflecting prism group 5 for each reflex reflector and to weld a plurality of sealing plates 6, so that the number of parts is large, the number of assembling steps is increased, and the cost is increased. was there. Further, there is also a problem that the leg 2a looks like a frame through the outer lens 2 when not lit, and the appearance is poor.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a good-looking vehicle lamp in which a simple-structured reflex reflector is provided in a part of an outer lens. .

[0005]

To SUMMARY OF THE INVENTION To achieve the above object, in the vehicle lamp according to the present invention, a plurality of reflex reflector in the outer lens is provided integrally on the rear side of the reflex reflector Au
In a vehicle lamp to which a sealing plate that covers the reflection prism group of the reflex reflector formed on the back surface of the tar lens is attached, each reflection prism group of the reflex reflector is provided adjacently , One sealing plate large enough to cover all the reflecting prism groups is attached to the outer lens via a plurality of legs provided between adjacent reflecting prism groups .

According to a second aspect of the present invention, in the vehicle lamp according to the first aspect, the cross section of the leg is formed to have a size corresponding to the light distribution control step element formed on the outer lens.

[0007]

[Function] Only one sealing plate is required to cover the reflection prism of the reflex reflector, and the number of legs is small.
Therefore, the number of components is small. In addition, when the lamp is not lit, only the legs on which the plurality of sealing plates are attached can be seen through the outer lens, and the appearance is better than in the prior art in which the legs are frame-shaped through the outer lens.

According to the second aspect of the present invention, the legs of the ceiling plate attached through the outer lens appear to be the same or similar to the light distribution control step of the outer lens.
There is unification as a pattern of the whole outer lens.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 show an embodiment of the present invention. FIG. 1 is a front view of a tail and stop lamp according to an embodiment of the present invention, and FIG. 2 is a horizontal sectional view of the lamp (shown in FIG. 1). 3 is a longitudinal sectional view of the lamp (a sectional view taken along a line III-III shown in FIG. 2), and FIG. 4 is a view showing a mounting of a sealing plate protruding from the outer lens side. It is an expansion perspective view of a leg.

In these figures, reference numeral 10 denotes a container-shaped lamp body.
A light chamber space is formed by assembling an outer lens 12 having a red color, which is a functional color, and a bulb 14 as a light source is inserted into two bulb insertion holes 11 of the lamp body 10, and a tail and stop is provided. A lamp is configured. On the inner peripheral surface of the lamp body 10, two parabolic light reflecting surfaces 11a are formed in the left-right direction, and the light of the bulb 14 is reflected by the light reflecting surface 11a and formed on the back surface of the outer lens 12. The light is diffused and distributed by the fish-eye step 13.

At approximately the center of the outer lens 12, a reflex reflector 20 is provided integrally. That is, a reflective prism group 22 is formed over the three rectangular regions 20A, 20B, and 20C on the central rear surface of the outer lens 12, and each of the reflective prism groups 22 converts light incident from the front of the lens into light. This constitutes a reflex reflector 20 that reflects light in the incident direction.
One sealing plate 30 that covers the three reflex reflectors extends on the back side of the reflex reflector 20, and has a structure in which dust and moisture entering the lamp room are unlikely to adhere to the reflection prism group 22. I have. Sign 1
Reference numerals 6 (16a, 16b, 16c) denote legs standing upright on the outer lens 12, between the rectangular areas 20A and 20B, 20B and 20C formed with the reflecting prism group 22, three vertically and horizontally. A sealing plate 30 is welded and fixed to these legs 16. A step 17 is formed on the outer side in the left-right direction of the leg 16 opposed to the left and right, while a ridge 36 formed with a step 37 is also provided on the welded part on the sealing plate 30 side,
The sealing plate 30 is positioned in the left-right direction by the engagement of these steps 17, 37 with each other.

The cross section of the leg 16 is rectangular and is formed to have the same size as one element of the fisheye step 13, and is formed at the same interval as the element row of the fisheye step 13. A fisheye step element is formed between each of the lenses 16b and 16c.
The outer shape of (16a, 16b, 16c) appears as a strip-shaped pattern in which dice are arranged in a vertically long manner.
Since the pattern is the same as the pattern of No. 3, uniformity of the design of the entire outer lens 12 is not impaired.

On the other hand, the ridges 3 of the sealing plate 30
6 has three legs 16 (16) on the outer lens 12 side.
a, 16b, 16c) can be engaged with the engagement protrusions 36a, 3
6b are provided, and as shown in FIG.
6a, 16b, 16c) and the engagement protrusions 36a, 36b are engaged, whereby the sealing plate 30 is positioned vertically.

The projections 36a, 36 on the side of the sealing plate 30 engaged with the gaps between the legs 16a, 16b, 16c.
The tip of 6b is located in the vicinity of the leg protruding surface of the outer lens 12, and the color of the leg forming region A and the leg non-forming region B seen through the outer lens 12 is uniform. That is, when the sealing plate 30 is not attached, since the leg 16 is erected in the leg formation region position A,
Although it looks darker than the leg non-formation area where the leg 16 is not erected, when the sealing plate 30 is attached, the engaging projections 36a and 36b are located near the back surface of the leg non-formation area B. The brightness difference in the areas A and B becomes smaller,
It is almost indistinguishable, and the presence of the leg cannot be determined.

In the above embodiment, the legs 16 (16a, 1
6b, 16c) are all welded to the sealing plate 30, but by forming the leg 16b at the center in the vertical direction lower than the legs 16a, 16c at the vertical position,
It is not always necessary to weld b to the sealing plate 30. That is, the three legs 16a, 16b, 16
In order to weld c, it is necessary to form all three legs with the same height, and it is troublesome to form the legs. On the other hand, if the upper and lower two 16a, 16c are welded, that much. The legs can be easily formed.

In the above embodiment, the legs 16 (16a, 1
6b, 16c) to the fisheye step 13
It is formed in a shape equal to the size of one element, but the size of the legs is not limited to the size of one element, the size of the element of the fisheye step, such as two elements or three elements The size should be suitable for the size. Also outer lens 1
In the case where the step formed in Step 2 is not a fish-eye step but a prism step, the cross section of the leg 16 may be formed in a shape corresponding to the element of this prism step.

[0017]

As is apparent from the above description, according to the vehicular lamp of the present invention, only one sealing plate is required to cover the reflecting prism of the reflex reflector, the number of legs is small, and the number of components is accordingly small. Since the number of points is small, the assembling is easy and the cost can be reduced. In addition, of lighting
At the time of non-lighting, only the legs on which a plurality of sealing plates are attached are visible through the outer lens, and the appearance is better than in the conventional technology in which the legs are frame-shaped.

According to the second aspect of the present invention, since the legs on which the sealing plate is visible through the outer lens appear to be the same or similar to the light distribution control step of the outer lens,
The steps of the entire outer lens are unified, and the presence of the legs is unclear, making them look better.
