しにくくなることなどのため、安全上、問題があった。[Prior Art] Conventionally, in vehicles such as automobiles, a method of warning vehicles behind to be careful when applying the brakes, reversing, changing the direction of travel, etc. is to turn on the brake lamp or reversing lamp located at the top of the bumper. This is normal. However, when it snows, the brake lights, etc. that are normally located at the top of the bumper are hidden by the snow and cannot be seen from the vehicle behind, and drivers of trucks, buses, etc. with high seats may not be able to see the brake lights when they are driving close to the vehicle. It is difficult to distinguish the lighting display of the brake lamps of the passenger car in front of the driver, and it is also difficult to clearly determine the brake operation status of the passenger car in front of the passenger car in front of the driver because the vehicle width lights are turned on at night. There was a safety issue due to this.

全性が高いという利点あるため、非常に有用である。[0004] This has the advantage that the light-emitting part serving as a warning light is located at a relatively high position, which not only makes it easy to see from vehicles behind, but also provides high safety because the light-emitting part is not hidden by snow even when it snows. It is very useful because of its advantages.

However, such a structure occupies the space between the rear seat and the rear glass, which is not only a design problem, but also an obstacle when cleaning the inside of the rear glass or between the rear seat and the rear glass. This has caused problems such as damage to high-mounted stop lamps.

どの有機合成樹脂、ガラスなどが好ましい。Here, the pad 8 is used by being sandwiched between the normally round columnar light guide 2 and the flat rear window glass 1 in order to bond them sufficiently firmly, and is a light-transmitting material. The materials can be appropriately molded into shapes corresponding to the respective materials. For example, acrylic, organic synthetic resins such as vinyl chloride, glass, etc. are preferable.

The pad 8 does not necessarily need to be used if sufficient adhesion to the rear window glass 1 is achieved. A light source 7 that emits light in synchronization with a stop lamp of a car causes light to enter the columnar light guide 2, and the incident light is scattered by the light scattering section 3.
It passes through the rear window glass 1.

うに射出成形されることもある。The window frame 6 is usually made of polyurethane resin or the like, and is formed by reaction injection molding or the like. It may be formed separately from the window glass, but it may also be injection molded integrally with the window glass.

On the other hand, when injection molding the window frame 6 so as to be integrated with the window glass, injection molding is performed with the columnar light guide 2 in contact with the rear window glass 1, and the columnar light guide is formed at the same time as forming the window frame. Body 2 is window frame 6
It may also be configured so that it is embedded in.

However, from the viewpoint of strength, it is preferable that they be bonded with an adhesive as in this embodiment. The adhesive is a light-curing adhesive,
A two-component adhesive or the like is preferably used. It may be colored with an appropriate transparency color.

ために好ましいことである。Furthermore, in order to prevent the light introduced into the columnar light guide from the light source from being emitted onto the surface of the portion of the columnar light guide 2 from which light is not emitted, an optical multilayer film made of a metal film or a metal oxide film is coated. It is preferable to provide a light-reflecting layer that improves light efficiency.

。As shown in FIGS. 3(a) and 3(b), the columnar light guide 2
A linear light scattering section 3 is provided in a part of the interior of the
is provided. Further, as shown in FIG. 3(b), the columnar light guide 2 has a structure consisting of a core portion 2b and a covering portion 2a around the core portion having a lower optical refractive index than the core portion.
This is preferable in terms of reducing light loss during light guidance and increasing light efficiency.

For the light scattering part 3, titanium dioxide (refractive index 2.903) powder is mixed with silicone resin (refractive index 1.4).
04) and dispersed therein was poured into a groove provided approximately parallel to the axis of the columnar light guide 2, and the resin was cured.

るように設けられることが好ましい。The light scattering section 3 scatters light by providing it in contact with the core section 2b as shown in FIG. 3(b). In addition, since the light scattered by the light scattering part 3 passes through the core part 2b and the covering part 2a and is emitted, the light scattering part should be arranged so that it is backward with respect to the exit surface. It is preferable that it be provided on the opposite side of the rear window glass 1 with respect to the portion 2b.

、芯部製造の後に被覆部を製造することも可能である。In the present invention, the columnar light guide is made by simultaneously heat-stretching and fusing a core material and a covering material, and a groove extending from the surface of the covering part to the core part is formed, and a groove is formed in the groove. It was manufactured by embedding a light-scattering substance. Of course, without relying on this, it is also possible to manufacture the covering part after manufacturing the core part.

ものが望ましい。[0026] The interface between the core and the covering, created in this manner, has a smooth mirror surface and functions as a good reflective surface for light transmitted within the core. The core material and coating material may be made of quartz glass, multicomponent glass, plastic, etc., but the coating material must have a lower optical refractive index than the core material. The light scattering substance to be dispersed in the silicone resin is preferably one with a high refractive index such as titanium dioxide.

ある必要はない。又、溝は曲線でも直線でも良い。It is also possible to roughen the groove itself and make it a light-scattering surface, in which case there is no need to embed a light-scattering substance. The shape and width of the groove are appropriately determined depending on the required amount of light, viewing angle, and the thickness of the columnar light guide. The groove does not have to be just one. Further, the groove may be curved or straight.

In order to return the light that has been transmitted to the end of the columnar light guide 2 without being scattered by the columnar light guide 2 into the columnar light guide 2 again, there is a , an aluminum plate was provided as the reflective layer 9. Although a halogen lamp is used as the light source 7, an LED or an existing brake lamp may be used, and as long as sufficient brightness is obtained, the lamp is not specified.
