Description

[Detailed Description of the Invention] The present invention relates to a third automobile brake light.

In a typical passenger car, two brake lights are arranged at both ends of the rear end of the vehicle. Therefore, the position of the brake light is low from the ground, and when braking while the following vehicle is approaching, the brake light is difficult to see from the following vehicle, which can be dangerous. There are cases where For this reason, it has been pointed out that if a third brake light is provided, it should be placed in a higher position to ensure that it can be seen by vehicles following, and this is being enacted into law in the United States.

This third brake light is installed at the rear of the vehicle interior,
It is conceivable to see the brake lights through the rear window, but the brake lights need to be of a certain size to make them easy to see. Therefore, large indoor brake lights not only obstruct the driver's ability to check the safety of the rear view through the rear window, but also make it difficult for the driver to see rearward as the light from the brake light reflects off the inner surface of the rear window. There is also a risk of doing so. Therefore, when installing a new third brake light on a vehicle, it is desirable to install it on the trunk directly below the rear window. However, the top surface of the trunk of a normal passenger car has a rearward slope, and the slope angle varies greatly depending on the type of car. Therefore, in order to reliably install the third brake light in a stable state on the trunk, it is necessary to manufacture the shape of the light body to match the inclination angle of the trunk, and it is necessary to prepare many types of light bodies. It won't happen.

The present invention was developed in consideration of these circumstances, and it is a third lamp that can be installed stably and reliably on various vehicles by minimizing the number of parts that need to be changed depending on the vehicle model and using a common lamp body. The purpose is to provide automotive brake lights. and,
The purpose of this adapter is to place the adapter on the trunk directly under the rear window so that the angle of inclination of the bottom surface is approximately equal to the angle of inclination of the trunk, and the optical axis of the lamp body is parallel to the road surface when the lamp body is fixed to the top surface. and a third automotive lamp body comprising a flat plastic casing in which a mirror and an incandescent light bulb are incorporated, the front surface of which is covered with a red transparent lens, and a lamp body whose lower surface is fixed to the upper surface of the adapter. Achieved by brake lights.

The present invention will be specifically described below based on embodiments shown in the drawings.

As shown in Fig. 3, the lamp body 10 is installed on the trunk T of the vehicle directly below the rear window RW.The casing 1 of the lamp body 10 is a plastic box with an open front. It has a flat shape with an area of 200 mm x 30 mm and a depth of 60 mm. The lower surface of the casing 1 is provided with a hole for an electric cord and a mounting hole (not shown) for fixing to an adapter 20 (described later), and a bag-shaped locking portion 1a is formed at the front of the lower surface. Casing 1
An incandescent light bulb 2, which is a krypton light bulb, is arranged inside the interior, and on the back of the incandescent light bulb 2 there is a main mirror 3 forming a paraboloid of revolution, and above and below there are sub-mirrors 4.
is placed, and light of a predetermined intensity is irradiated backward. Incidentally, the incandescent light bulb 2 and the mirrors 3, 4 are assembled together in advance and are incorporated into the casing 1 as a unit. Since the shape of the casing 1 is flat, the heat from the incandescent light bulb 2 is transferred to the casing 1.
When there is a risk that the inner surface of the inner surface may be locally heated to a high temperature and cause thermal deformation, a heat shield plate 6 is attached to the upper inner surface. Furthermore, if necessary, it is preferable to attach it to the lower inner surface as well. And casing 1
The front surface of the lens 5 is covered with a red plastic plate.

Next, the adapter 20 has an upper surface 21 having a surface shape along the lower surface of the casing 1, and a lower surface 22 inclined at an angle Θ with respect to the upper surface 21. This angle Θ is approximately the same as the inclination angle Θ' of the trunk T of the vehicle type to which it is attached, and when the adapter 20 is fixed on the trunk T by an appropriate means, the upper surface 21 becomes the lamp body when the lamp body is attached to this surface. The optical axis of is parallel to the road surface. A plurality of locking protrusions 23 are protruded from the upper surface 21 and are engaged with the mounting holes of the casing 1.
An edge 24 protrudes in front of 1, and this edge 24 engages in the locking portion 1a. Incidentally, since the inclination angle Θ' of the trunk T varies greatly depending on the vehicle type as described above, adapters 20 having angles Θ corresponding to the vehicle types to which the brake light is installed are prepared as many as the number of vehicle types.

Once the type of vehicle to which the brake light with the above configuration is to be installed is determined, an adapter 20 having an inclination angle Θ approximately equal to the inclination angle Θ' of the trunk T of the vehicle type is selected, and is appropriately installed on the trunk T directly below the rear window RW. fixed by means. The locking protrusion 23 and edge 24 of the upper surface 21 are respectively engaged with the mounting hole of the casing 1 and the locking portion 1a, thereby fixing the lamp body 10 to the adapter 20. However, the fixation of both is not limited to this embodiment, and may be fixed using adhesive or screws, for example, but in any case, the optical axis of the lamp body 10 is approximately parallel to the road surface when they are fixed. Therefore, the light is emitted horizontally.

In this way, the lamp body 10 is constant regardless of the vehicle type, and only the adapter 20 needs to be prepared depending on the inclination angle Θ' of the trunk T. Therefore,
Even if the vehicle model is different, only the adapter 20 needs to be selected accordingly, and a common lamp body 10 can be used, so it is possible to minimize the number of parts to be changed depending on the vehicle model. and,
Even though the installation location is on the trunk T directly below the rear window RW, the casing 1 is low in height and wide and flat, so even if the area of the front irradiation port is increased, a blind spot will occur in the rear window RW. figure,
It does not interfere with safety confirmation at the rear.
