Description

[Detailed description of the invention] [Field of industrial application] The present invention is a lamp that prevents reflected light and leakage light into the vehicle interior, which occurs in high-mounted lamps installed inside the rear window of automobiles. It's about structure.

[Conventional technology]

2. Description of the Related Art In some cases, a lamp such as a high-mounted stop lamp is installed on the inside of a rear window of a vehicle, particularly a passenger car, and is turned on in response to the depression of the brake. An example of this lamp structure will be explained with reference to the drawings. As shown in FIG. A lamp consisting of a shade 4 extending from the rear window 6 is mounted in contact with the rear window 6 via a protector 2 made of an elastic material such as rubber. Note that the lamp is normally mounted on the package tray 7, but in the case of the example shown in FIG.
is fixed with a bolt through the holder 10 to the sixth
As shown in the figure, the package tray 7 provided with the lamp insertion part 7a is attached from the rear of the lamp body 1,
This prevents light from the lamp from leaking into the interior of the vehicle.

[Problem that the invention attempts to solve]

Therefore, in the conventional lamp mounting structure, the shade 4 extending in front of the lens 3 of the lamp has an expanding shape, and the protector 2 fitted to the tip of the shade 4 also has a shape that extends from the inside of the shade 4, that is, from the lamp. The shape was such that it did not project in a direction that would not block the light.

On the other hand, since the window glass has a considerable thickness, there is a phenomenon in which light from the lamp enters the window glass, is refracted and reflected. Therefore, depending on the thickness and angle of inclination of the windshield, the light from the lamp may be reflected on the rear window, or the reflected light B may leak into the interior and be reflected on the inner mirror 8 as shown in Figure 4, causing the driver to There is a problem that it dazzles and is not desirable for safety.
Furthermore, as shown in FIG. 5, when the light from the lamp leaks into the rear window and the area around the lamp becomes shiny, the appearance becomes unsightly.

[Means for solving problems]

The present invention is to prevent the above-mentioned reflected light into the vehicle interior and light leakage from the lamp cover.The lamp structure of the present invention is installed on the inside of the vehicle interior of the rear window, and the front side of the lamp is covered with a protector. A feature of the lamp structure is that the lamp is in contact with the windshield through the lamp, and the protector fitted to the upper edge of the lamp front is extended downward to prevent light from reflecting toward the passenger compartment. shall be.

In the present invention, the protector is fitted onto the tip of the shade provided on the front surface (front side) of the lamp, and extends along the window in a direction that narrows the area of the shade, that is, the area of the lamp lens. This protector is extended because the light from the lamp usually leaks from above the lamp, so the protector fitted to the upper edge of the lamp is extended.
Of course, the portion fitted to the lower edge or side edge may be extended depending on the case. If necessary, a protrusion is provided on the extended portion, and the protrusion is provided in a direction along the circumferential shape of the lamp, that is, the edge of the shade.

The extension portion of the protector may be made integrally from the beginning, or may be made separately and attached later.

[Effect]

In the present invention, as described above, by extending the protector in a direction that narrows the area in front of the lamp, it is possible to block the lamp light that would conventionally be reflected to the inside of the vehicle cabin beyond the shade due to the birefringence of the light. Furthermore, when a protrusion is provided at the tip of the extension, the protrusion can ensure close contact of the protector to the window and also ensure the blocking of lamp light.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3, but the present invention is not limited to these examples.

FIG. 1 is a sectional view showing an embodiment of the present invention. In the figure, the same types as those shown in FIG. 7 are given the same reference numerals, and the explanation will be omitted.

In FIG. 1, 2 indicates a conventional size protector, and 2' indicates an extended section according to the present invention. As can be seen from the figure, when the light ray A from the bulb 5 is diffused by the lens 3 and emitted diffusely to the outside of the lamp, the conventional protector does not have an extension shown by 2'. Of the light that enters the window glass 6, the light that is reflected without exiting from the surface of the glass 6 becomes reflected light ray B and enters the vehicle interior, and this reflected light exits to the front of the vehicle. Therefore, some of the light from the bulb 5 becomes reflected light B, passes through the inner mirror 8, and reaches the driver, causing dazzling. Furthermore, at night, there were cases in which the reflected light was further reflected from the rear by the front window.

As shown in FIG. 1, when the protector 2 is integrally formed with an extension 2', the light indicated by ray A is cut off by the extension 2', and the light indicated by ray A is incident on the window glass 6. Even if the reflected light is later reflected toward the vehicle interior, the reflected light hits the protector 2 and is not reflected back into the vehicle interior. Therefore, the length of the extended portion 2' must be such that the light that enters the window glass from the side edge of the protector 2+2' and is reflected, as shown by ray A, hits the protector.

Note that a protrusion 21 is formed on the protector 2 to ensure close contact with the window glass 6, but if the protrusion 21' is also provided at the lower end of the extended portion 2', light can be blocked and the protector 2 ' can be brought into contact with the window glass 6 more reliably. Furthermore, by creating a space surrounded by the window glass 6 and the protector 2+2' between the two protrusions 21 and 21', the reflected light can be further refracted when entering this space, so that it can be effectively The reflected light can be extinguished, and the light leaking around the lamp as shown at C in FIG. 5 can be extinguished.

In addition, in FIG. 1, 7b is a lamp cover,
Reference numeral 11 indicates a body, and reference numeral 12 indicates a holding member that holds the window glass.

Figures 2 and 3 are diagrams showing other examples of the protector used in the present invention.
An example is shown in which the part is not made integrally with the conventional protector part, but is made separately and attached to the protector 2.

In the example shown in Fig. 2, a part of the protector 2 is cut out so that a fitting groove is formed when the protector 2 is attached to the shade 4, and an extension member 2' provided with the fitting piece 2 is added later. This is an example in which it is installed. 22' is a protrusion formed on the fitting piece 22 to prevent the extension member 2' from falling off.

The example shown in FIG. 3 is an example in which a fitting groove is provided in the protector 2, and a fitting piece 22 that fits into the fitting groove is provided in the middle portion of the extension member 2' in the thickness direction. In this example, if necessary, a protrusion may be provided on the fitting piece to prevent it from falling off, or conversely, a protrusion may be provided in the fitting groove and a corresponding groove may be provided on the fitting piece. Good too.

In the example of FIGS. 2 and 3, the extension member 2'
does not necessarily have to be made of the same material as the protector 2. Further, only the fitting piece portion may be made of a different material.

[Effect of idea]

As described above, the present invention extends the protector fitted to at least the upper edge of the lamp downward;
By increasing the width of the protector relative to the window glass, it is possible to block the reflected light that was conventionally reflected by the window glass and entered the vehicle interior, and the light that leaked out to the periphery of the lamp cover. In addition, if the protector extension member is made separately and attached to a conventional protector, protectors with different lengths can be attached depending on the degree of inclination of the windshield.
Further, by adjusting the insertion amount of the fitting piece of the extension member, reflected light, etc. can be blocked, and the driver can be effectively prevented from being dazzled by the reflected light.

Although the present invention has been mainly described above with respect to a lamp mounted on a rear window, it can also be applied to a lamp mounted on a front window etc. based on the same idea.
