Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted glass display applied to, for example, a high mount stop lamp which emits light in synchronization with a stop lamp of an automobile.

[0002]

2. Description of the Related Art Conventionally, in vehicles such as automobiles, a stop lamp, a backward light, and a turn indicator located above a bumper have been known as a method of urging a vehicle behind to pay attention when operating a brake, moving backward, and changing a traveling direction. It is normal to light such as. However, in the case of a stop lamp located above a normal bumper, when the snow falls, the stop lamp is hidden from the snow and cannot be seen by the vehicle behind. For safety reasons, it is difficult to determine the lighting display of the stop lamp of a passenger car, and it is difficult to clearly determine the brake operation state of the passenger car in front because the side lights etc. are lit at night. There was a problem.

In order to solve such a problem, in recent years, the one in which the light emitting portion of the stop lamp is placed at a relatively high position near the rear window glass has been proposed and put into practical use, and is called a high mount stop lamp. .. This is because the light emitting part, which is a warning light, is located at a relatively high position, so that not only is it easy to check from a vehicle behind, but there is also the advantage that the light emitting part is not hidden by snow even when it is snowing. ..
As such a high mount stop lamp, there is known one which is arranged inside a rear window glass of an automobile and irradiates light rearward through the rear window glass.

[0004]

However, since the conventional high mount stop lamp is installed between the rear seat and the rear window glass and occupies the space between the rear seat and the rear window glass, this space is not provided. Not only is it impossible to effectively use the vehicle, but there is also the problem that it becomes an obstacle when cleaning the inside of the vehicle.

Further, when installing the lamp, it is necessary to pull the power cord around, and therefore, it takes time and labor to open a hole in the rear parcel shelf. Further, there is a problem that the lamp may be damaged by catching the cord during cleaning and the lamp cannot be simplified because of the cord.

Moreover, the glass used for the rear window glass and sunroof of an automobile is usually a curved surface instead of a flat surface, but the light emitting device used for the conventional high mount stop lamp has a predetermined size. However, since it does not have flexibility, there is a problem that it is difficult to attach it so as to fit the curved surface of glass.

Therefore, the object of the present invention is to make effective use of the space between the rear seat and the rear window glass, not to obstruct the cleaning, and to have a simple design. An object of the present invention is to provide an in-vehicle glass display that can be attached so as to fit a curved surface of glass.

[0008]

In order to achieve the above object, a glass display for a vehicle according to the present invention is provided with a circuit pattern formed on a glass surface of an opening of an automobile and the circuit pattern connected to the circuit pattern. And a chip type light emitting diode is used as a light emitting element of the light emitting module.

In a preferred aspect of the present invention, the light emitting module includes a flexible circuit board on which the chip type light emitting diode is mounted and a flexible circuit board mounted on the surface opposite to the component mounting surface of the flexible circuit board. It has a resin substrate and an optical decoration panel attached so as to cover the component mounting surface of the flexible circuit board. In this case, as the decorative panel, for example, a diffusion plate, a coloring plate, a flat lens or the like is used.

In a further preferred aspect of the present invention, the chip type light emitting diode is connected to a predetermined electric circuit through the circuit pattern so that the chip type light emitting diode emits light in synchronization with a stop lamp or a turn signal lamp of an automobile. There is.

In still another preferred aspect of the present invention, the circuit pattern is formed of an Ag-based thick film. By using such an Ag-based thick film, it becomes easy to solder a terminal fitting or the like.

[0012]

In the vehicle-mounted glass display of the present invention, the circuit pattern is formed on the glass surface of the opening of the automobile, and the light emitting module is connected to the circuit pattern and mounted on the glass surface, which is effective in the vehicle. A wide space can be secured.

Further, since the circuit is connected to a predetermined electric circuit through the circuit pattern formed on the glass surface, it is not necessary to draw a cord for supplying power, and therefore,
There is no need to worry about the cord being caught and damaged during cleaning, and the design can be simplified.

Further, as a light emitting element of the light emitting module,
By using the chip type light emitting diode, the light emitting module can be made thin and can be fitted and attached to a glass surface such as a rear window glass or a sunroof, so that the design can be simplified and the aesthetic appearance can be improved.

In this embodiment, the on-vehicle glass display of the present invention is applied to a high mount stop lamp, but the on-vehicle glass display of the present invention is not limited to the high mount stop lamp but also a turn signal lamp. It can also be applied to.

As shown in FIG. 1, a rear window glass 1
The defogger heating wire 2 is formed in the center of the inner surface of the vehicle. Further, two circuit patterns 3a and 3b formed of Ag-based thick film conductors are formed on the lower edge portion of the inner surface of the rear window glass 1 so as to extend from both sides toward the center. This circuit pattern 3a, 3b
Can be formed, for example, by printing a silver paste in which glass frit, silver powder, and a binder are mixed and firing the paste, and can be simultaneously formed in the same process as the defogger heat wire 2.

At the ends of the circuit patterns 3a and 3b located on both sides of the rear window glass 1, terminal fittings 4 are respectively provided.

The light emitting module 6 is shaped so as to sandwich and fix both ends thereof.
A coating film 7 made of black ceramic paint is formed on the peripheral edge of the inner surface of the rear window glass 1. The coating film 7 prevents the terminal fittings 4a, 4b, 5a, 5b from being seen from the outside. Is becoming However, the portion located on the light emitting surface of the light emitting module 6 is an opening where no coating film is formed.

2 to 5 together, the light emitting module 6 has a flexible circuit board 10 to which a plurality of chip type light emitting diodes 8 are soldered at predetermined intervals.

In this embodiment, the light decoration panel 12 is composed of a polycarbonate resin plate having a thickness of 0.5 mm and one surface of which has a sliding shape (grinding grain size # 500). Thereby, the light from the chip type light emitting diode is scattered, and the decorativeness can be improved.

Therefore, the light emitting module 6 is extremely thin with a thickness of about 4 mm, and since each member has flexibility, it can be curved so as to be in close contact with the curved surface of the rear window glass 1. it can. Then, both ends of the light emitting module 6 are soldered to the circuit patterns 13a and 13b of the rear window glass 1 and the terminal fitting 5 is soldered.
