Description

[Detailed description of the invention] <Industrial application field> The present invention is a high-mounted stop lamp for automobiles that is installed close to the inside of the rear window to notify following vehicles that braking is in progress. It is related to.

<Prior Art> This type of strut lamp must be constructed and installed so that the light when turned on does not enter the driver's eyes through a room mirror or the like.

Therefore, conventionally, as shown in FIG. 4, an end rubber 3 was attached to the front opening 2 of the lamp body 1, and the end rubber was brought into close contact with the rear window B to prevent light leakage into the interior of the vehicle. However, in this conventional method, when installing the lamp A, the end rubber 3 is often rubbed against the rear window B, causing it to become distorted or peeled off from the lamp body. If the width of 3 was not made considerably wide, there was a problem that the direct light L from the bulb would be reflected by the rear window B and leak into the inside of the car.

On the other hand, if the lamp A is moved away from the rear window B as shown in FIG. 4, causing a problem where light is reflected and leaks into the inside of the vehicle.

<Problems to be solved by the invention> The present invention has been made in view of the above-mentioned conventional problems, and is designed to eliminate the risk of light from the lamps leaking into the inside of the vehicle even if the lamps are not placed in close contact with the rear window. The present invention aims to provide a high mounted strut lamp for automobiles.

<Means for solving the problem> The high-mounted stop lamp for automobiles of the present invention which achieves the above object has a shade plate extending along the rear window at the front opening of the lamp body, and the shade plate It is characterized by having a roughened surface for preventing light leakage formed on the outer surface.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The lamp A is composed of a lamp body 1, a bulb 5, and a lens 6, as in the conventional case, and is installed close to the inside of the rear window B with the inside of the car covered by a cover C.

The lamp body 1 is formed into a desired shape, and a lens 6 is installed in its front opening 2, and a shade plate 4 is installed.
be extended into the same body or separate bodies.

The shade plate 4 is formed along the inner surface of the rear window B and extends from the front opening 2 of the lamp body 1 either as a single piece or as a separate piece. At this time, the shade plate 4 may extend all the way around the front opening 2 of the lamp body 1, or as in the illustrated embodiment, the shade plate 4 may extend over the upper part of the front opening 2 where light leakage tends to have a negative impact on the driver. It may be arranged to extend only to. Then, a rough surface 7 for preventing light leakage is formed on the outer surface of this shade plate 4, that is, the surface facing the rear window B.

The light leakage prevention rough surface 7 is for preventing the direct light L from the bulb 5 from being reflected by the rear window B and the shade plate 4 and leaking to the inside of the vehicle, and the incident light is directed toward the rear window B side. Form to be diffused. That is, the rough surface 7 for preventing light leakage may be formed in a frosted or embossed shape so as to diffuse the incident light L toward the rear window B, or may be formed in a cross-sectional shape as shown in FIGS. 2a and 2b. Triangular prism shape and the same c
As shown in g to g, the cross section may be formed into a generally concave or convex curved shape. At this time, the pitch and angle may be the same over the entire surface, or may be partially different. Further, this light leakage prevention rough surface 7 may be parallel to the inner surface of the rear window B, or it may be formed so as to approach the inner surface of the rear window B as it reaches the tip of the shade plate 4, as shown in FIG. 2h. Furthermore, as shown in FIG. 3, the pitch line may be a straight line a, a curved line b, or discontinuous.

Therefore, the high mounted stop lamp A for automobiles of the present invention has a rough surface 7 for preventing light leakage of the shade plate 4.
is installed on the vehicle body so as to be close to the interior side of the rear window B.

<Effects of the invention> Since the high-mounted stop lamp for automobiles of the present invention is constructed in this way, there is no risk of light from the lamp leaking into the inside of the vehicle even if the front opening is not in close contact with the rear window. Therefore, unlike conventional products, there is no need to attach an end rubber to the front opening, thereby reducing costs and improving installation workability.

Moreover, it does not require any special parts,
Since the shade plate and the rough surface for preventing light leakage can be molded into the same body at the same time when molding the lamp body, it is possible to further reduce costs.

Therefore, the intended purpose can be achieved.
