Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to stop lamps installed on the top side of the rear window of automobiles. do.

0002

[Conventional technology]

In addition to the normal stop lamp that lights up in conjunction with brake operation, the rear window The one with an optional stop lamp attached to the top of the glass is the It has been proposed as No. 61-129631, Utility Model Application Publication No. 62-165140, etc. These stop lamps have multiple light sources inside the case, and the case is used as a rear window. It is installed on the door glass or car body.

0003

[Problem that the idea aims to solve]

As mentioned above, in the past, the light source was placed inside the case, so the overall size was When installing on a windshield that is curved or obstructs rear visibility, be sure to The base itself must be curved to fit the glass, and depending on the car model, the glass Since the degree of curvature differs, the types of vehicles to which it can be applied are limited.

0004 Also, the stop lamp placed at the top of the rear window glass is only for the light source. It is preferable to emit light in a continuous band rather than emit light in streaks. others Therefore, in the conventional technology, a lens plate is placed in front of the light source to orient the light. The overall thickness of the stop lamp is increased by the zoom plate.

[0005]

[Means to solve the problem]

In order to solve the above problems, the stop lamp according to the present invention has an embedded LED chip. The structure consists of a series of transparent resin bodies, and the front surface of the transparent resin body is a flat light emitting surface. The light emitting surface of the window is attached to the indoor side of the window glass via an adhesive film, and the transparent The back surface of the resin body is a parabolic reflecting surface, and the LED is placed approximately at the focal point of this reflecting surface. Placed.

[0006]

[Effect]

The light emitted from the LED is diffused and reflected by the parabolic reflective surface of the transparent resin body, and is reflected backward. It appears to emit light in the form of a single band.

[0007]

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, Figure 1 is based on the present invention. A perspective view of such a stop lamp for an automobile, FIG. 2 is a plan view of the stop lamp, and FIG. Figure 4 is a rear view of the same stop lamp, and Figure 4 is a rear view with the same stop lamp installed. This is an overall view of Indian glass.

[0008] First, as shown in FIG. 4, the stop lamp 1 according to the present invention is installed on the rear window of an automobile. It is provided on the upper side of the door glass 2. The peripheral edge of the rear window glass 2 has a Lamic color 3 is formed, and the stop lamp is overlapped with this ceramic color 3. Wiring 4 for power supply to 1 is printed.

[0009] The stop lamp 1 is made up of a plurality of LED units 5 arranged in series. This LED light The knit 5 has the above-mentioned print inside a substantially hemispherical transparent resin body 6 made of epoxy resin or the like. An LED chip 7 connected to the wiring 4 is embedded.

0010 Further, the front surface of the transparent resin body 6 facing the rear window glass 2 is a flat light emitting surface 6a. This light emitting surface 6a is attached to the rear window glass 2 via a transparent adhesive film 8. It is attached to the side of the room.

[0011] Furthermore, the back surface of the transparent resin body 6 is mirror-finished and then aluminum vapor-deposited to form a parabolic reflection surface. The reflective surface 6b has a surface 6b, and the LED 7 is disposed approximately at the focal point of the reflective surface 6b. stop The upper, lower and left and right sides of the back surface of the transparent resin body 6 are flat reflective surfaces 6c. However, this reflective surface 6c is expanded toward the front (glass surface). in this way By expanding the reflective surface 6c toward the front, the reflective surface 6c of the adjacent transparent resin body 6 and A gap is formed between them, allowing you to slide along the curved glass surface without causing any scratches. It becomes possible to bend the top lamp 1.

0012 In addition, as shown in FIG. 5, the angle of the reflecting surface 6c that expands toward the front is By placing it above the extension line of the light emitting surface, you can reduce the loss of light from the cut end (boundary with the light emitting surface). In addition, the light emitted from the LED chip 7 can be diffused, especially if a lens plate is installed. Even if it is not visible, the light emitted from the stop lamp 1 appears to be in the form of a single band.

[0013] Note that the light emitted from the LED chip 7 is reflected, and this reflected light is reflected to the LED chip 7. In order to avoid interference, a protrusion 9 is provided at the center of the reflective surface as shown in FIG. The reflected light is reflected by the LED chip 7, and as shown in Figure 6, the LED chip 7 is located inside the focal point. A recess 10 is formed in a part of the reflective surface so that the reflected light can be emitted in parallel even if the chip 7 is buried. It may be provided. When the recess 10 is provided, the thickness of the LED unit is further reduced. It is also possible to reduce the loss of light from the cut end.

[0014] FIG. 7 is a sectional view of a stop lamp according to another embodiment, and in this embodiment, The LED unit 5 is formed into a soft resin molded body 11 made of urethane or silicone resin. He is trying to bury it in the recessed part 12 which has been formed. By doing this, the transparent resin body 6. In particular, the aluminum vapor deposited film formed on the back surface of the transparent resin body 6 can be protected.

[0015] 8(A) and (B) show another example of the transparent resin body 6, which is shown in FIG. 8(A). Even if the light emitting surface 6a is made into an oval shape as shown in FIG. 8(B), it can also be made into a hexagonal shape as shown in FIG. Good too.

[0016]

[Effect of the idea]

As explained above, according to the present invention, a plurality of transparent resin bodies whose back surfaces are reflective surfaces are used. An LED chip is embedded inside, and this transparent resin body is continuously bonded with an adhesive film (layer) interposed therebetween. Since it is mounted directly on the surface of the rear window glass, the number of parts is reduced. It is easy to manufacture, and since the thickness of the part where the adjacent transparent resin body touches is thin, it can be easily manufactured using glass. The stop lamp can be bent and attached to match the curved shape of the bus.

[0017] In addition, the back surface of the transparent resin body is made into a parabolic reflecting surface, and part of this is made into a flat surface, a convex surface, or a parabolic reflecting surface. By making it a concave surface, it diffuses the light without using a conventional diffuser lens plate, resulting in an overall improvement of 1. The book can be made to emit light in the form of a band.

[0018] Furthermore, since the case and diffuser lens plate can be omitted, the necessary light emitting area can be secured. Since the overall dimensions, especially the thickness and height, can be reduced, the rear visibility is not obstructed. Also, it does not get in the way when getting on and off.
