Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle light suitable for use as a warning sign light installed at the rear of an automobile body to warn vehicles behind. .

[Conventional technology]

Car warning sign lights are usually installed near the rear window at the driver's eye level.
Normally, it is not lit, but when braking, it lights up brightly along with the brake lights to draw the attention of drivers of cars behind, preventing rear-end collisions, and ensuring road traffic safety. Fig. 4 shows a conventional example of this type of warning indicator light, in which 1 is a lamp case that houses a light source (not shown);
is a light guide plate that closes the opening of the lamp case 1, and on the back side of this light guide plate 2 there are letters, symbols, etc. made up of numerous stipples (small conical recesses), such as the words "GOOD BY". A display section 3 is displayed. The display section 3 is normally not legible, but when the light source is turned on and backlit during braking, it becomes legible and serves as a message to following vehicles.

[Problem that the invention seeks to solve]

However, such conventional warning sign lights have the problem of placing too much emphasis on function, making them look dull and lack smartness, and not matching the design of the vehicle itself. Moreover, if the lamp case 1 is small, it will be difficult to stand out, and if it is large, the effective area of the rear window will be reduced, which will hinder visibility behind the vehicle body. Furthermore, since the light only comes on when the brake is pressed, it does not always alert people, and there are problems with its poor alert function.

Therefore, the present invention solves the above-mentioned conventional problems, increases the attention calling function, matches well with the car body design, and exhibits a spoiler-like effect for braking action and reducing lift at the rear of the car body. The aim is to provide a novel vehicle lighting device.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a lamp case that is rotatably arranged in a vertical direction in a lamp storage recess provided on the rear upper surface of a vehicle body; The lamp case includes a light source disposed inside the case and a drive device for raising and lowering the case, the rear end surface of the lamp case forms a first illumination part that illuminates the rear of the vehicle body when the case is stored, and the lower surface of the lamp case A second lighting section is formed to illuminate the rear of the vehicle body when the vehicle is standing up.

[Effect]

In the present invention, the first lighting section is illuminated when the lamp case is in the stored state, and the second lighting section is illuminated when the lamp case is in the upright state.
The lighting section is illuminated. Furthermore, when the lamp case is stood up, it creates air resistance, which brakes the vehicle body and reduces lift at the rear of the vehicle body.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Fig. 1 is a sectional view showing an embodiment of the present invention applied to a warning sign lamp, Fig. 2 is an enlarged sectional view of the main part of the same sign lamp, and Fig. 3 is a perspective view of a car equipped with the same sign lamp. It is a diagram. In these figures, a light storage recess 13 for storing a warning indicator light 12 is formed on the rear upper surface 11 of the vehicle body 10 to be long in the left-right direction of the vehicle body 10, and its rear end is open to the rear surface 14 of the vehicle body 10. .

The warning indicator lamp 12 includes a lamp case 15 that is flat and has a substantially airfoil cross-sectional shape and is housed in the lamp storage recess 13. It is rotatably supported. The upper surface of the lamp case 15 forms substantially the same plane as the rear upper surface 11 of the vehicle body 10 in the stored state shown by the two-dot chain line in FIG. On the other hand, openings 17A and 17B are formed on the rear end surface and the bottom surface of the lamp case 15, respectively, and these openings 17A and 17B are respectively covered by lenses 18 and 19. There is. The lens 18 is made of a translucent lens colored red, for example, and is substantially vertical when the lamp case 15 is stored and faces toward the rear of the vehicle body. Inside the lamp case 15, there is a printed circuit board 2 in close opposition to the lens 18.
0 is arranged substantially parallel to the lens 18, and on the surface of the printed circuit board 20 facing the lens 18, a large number of light emitting diodes 21 as light sources are mounted in an m×n matrix at appropriate intervals. The first illumination section A is configured together with the lens 18. The light emitting diode 21 is normally turned on, that is, when the lamp case 15 is housed in the lamp storage recess 13, and illuminates the lens 18. In this case, the lens 18 may have a stippled message displayed on its inner surface. First and second inner lenses 22 and 2 are provided between the lens 18 and the printed circuit board 20.
3 are interposed so that they are parallel to each other.

The first inner lens 22 is made of a transparent lens as shown in FIG. The beam is emitted almost horizontally to the rear of the vehicle when the beam is fully activated. Said second inner lens 23
consists of a lens colored red, and on its surface is a diffusion lens 27 consisting of many small concave lenses.
are formed densely, and a condenser lens 28 made of a concave lens with a large curvature is formed closely on the back surface.

The lens 19 is made of a smoked lens, and inside the lens 19, first and second inner lenses 29, 30 similar to the first illumination part A and a printed circuit board 24 are arranged at a predetermined interval so that they are parallel to each other. It is arranged at a distance. A large number of light emitting diodes 25 constituting a light source are arranged on the surface of the printed circuit board 24 facing the second inner lens 23.
are mounted in a 0×P matrix at appropriate intervals (10 mm). These light emitting diodes 25 constitute a second lighting section B together with the lenses 19, 29, and 30, and the lamp case 15 constitutes the first lighting section B.
As shown by the solid line in the diagram, the lens 19 is rotated upward by a predetermined angle and illuminated in an upright state tilted backward.

Reference numeral 31 denotes a drive device, such as a motor, for vertically rotating the lamp case 15, and the rotation of its output shaft 32 is transmitted via a reduction gear train 33 to a gear 34 fixed to one end of the horizontal shaft 16. is configured to be The drive motor 31 is driven when the brake is depressed, for example, and raises the lamp case 15 to the state shown by the solid line in FIG. At this time, as mentioned above, the light emitting diode 25 lights up,
By brightly illuminating the smoke lens 19, a stop warning is given to the driver of the following vehicle.

Thus, in a warning sign lamp having such a configuration, the first illumination part A is normally illuminated as a tail light, and the second illumination part B is illuminated, for example, when braking, so that a warning can always be given to the driver of the following vehicle. become. Therefore, it is highly effective in alerting drivers of following cars, and it is possible to prevent rear-end collisions and the like. Further, since the warning indicator light 12 is normally housed in the light storage recess 13 and constitutes a part of the vehicle body 11, it does not spoil the appearance of the vehicle body 11, and on the other hand, it stands up when braking, so it can be retracted. Like headlamps, they are highly functional, and because they create air resistance, they function as a braking function and as a spoiler, reducing lift at the rear of the vehicle. Furthermore, since the second illumination section B has a larger illumination area than the first illumination section A, a variety of messages can be displayed in the second illumination section B as needed, which contributes to the diversification of displays. Are better. In addition, this display includes characters such as "STOP" and "Please go first", a parking display with a flashing "△" mark,
Furthermore, an example of displaying the turn direction by sequential "arrows" may be considered. In addition, since it is placed at approximately eye level of the driver, it is easy to catch the driver's eye, further increasing the attention-grabbing effect.

Here, until the lamp case 15 starts to rise from the stored state and the lens 19 becomes visible from the rear, the light directed toward the rear of the vehicle body is significantly reduced, temporarily reducing the warning function. Therefore, in order to prevent this, the present invention provides an inclined reverse slope 35 at the connection part between the inner bottom surface of the lamp housing recess 13 and the rear surface 14 of the vehicle body, thereby directing the light from the second lighting section B almost horizontally toward the rear of the vehicle body. I try to make it reflect.

In addition, in the above embodiment, the first and second illumination parts A,
Although the case where a warning display is performed by B is described, the present invention is not limited to this in any way, and it goes without saying that it can also be used for direction indication, park display, etc.

〔Effect of the invention〕

As explained above, in the vehicle lamp according to the present invention, the lamp case is housed in the lamp storage recess provided on the upper surface of the rear end of the vehicle body in a manner that it can be raised and lowered. The first display illuminates the rear of the vehicle when the vehicle is in the stored state, and the second illumination illuminates the rear of the vehicle when the vehicle is standing up, so it matches well with the vehicle body and is highly fashionable. It can be expected to have a positive effect and a lift suppression effect.
