The rotational position of can be adjusted by an adjustment means described later. Since the number of lamps may be one or three or more, and both lamps 1, 1a and their associated devices can be constructed identically, only one lamp 1 will be referred to in the following description.

Appropriate configurations can be adopted for the structure of the lamp 1 itself, its support mode, the rotation drive device for the lamp 1, and the adjusting means for adjusting the rotation position of the lamp, and an example thereof will be clarified below.

In FIGS. 2 to 4, a lamp 1 includes a cup-shaped housing 2, a light bulb 3 housed and supported within the housing, a reflector 4 that reflects light from the light bulb 3, and a lamp fixed to an opening of the housing 2. It has a lens 5 and a lamp cover 6 that covers the housing 2, and the reflector 4 is housed inside the housing 2 and is attached to the housing 2.
The lamp cover 6 is also fixed to the housing 2. The light bulb 3 is connected via a harness 7 to a battery 27 (FIG. 6) supported by the vehicle body. Further, as shown in FIG. 3, a slit 8 is formed in the housing 2, and a fisheye lens 9 is fixed to the outer opening of the slit 8, so that the interior of the lamp 1 can be seen through this lens 9.

The lamp housing 2 is attached to the vehicle body 10 by a hinge 11.
When the lamp 1 is in the non-use position as shown by solid lines in FIGS. 1B and 2, the lamp 1 It is housed in a storage section 12 formed by recessing the outer panels of No. 10. At this time, the lens 5 faces downward, the lamp cover 6 is exposed to the outside, and the outer surface of the cover 6 is flush with the outer surface of the vehicle body portion 10a adjacent to the storage portion 12 and the luggage door 14. Therefore, lamp 1 is not visible at all,
It is possible to prevent the lamp 1 from deteriorating the appearance of the vehicle body. Reference numeral 13 in FIG. 2 is a stopper fixed to the lamp cover 6, and the lamp 1 is
2, the lamp is supported by a stopper 13.

For example, when the surroundings are dark, such as at night, the lamp 1 is rotated around the hinge 11 by a motor to be described later to the extreme use position shown by the chain line in FIG. 2 (the state shown in FIG. 1 a), By lighting the light bulb 3 of this lamp 1, the rear can be illuminated. that time,
As shown by the broken line in Figure 2, the lamp 1 can be stopped at an intermediate use position to illuminate the rear, so when the driver puts the car in the garage, the driver can steer the car while illuminating the area he or she wants to see. Able to perform driving operations. If the light intensity of the light bulb 3 is made higher than the light intensity of conventionally used rear lamps or backlight lamps, and it is possible to illuminate a far-off area behind the car, it will be possible to illuminate not only when parking the car but also when driving your own car. This is advantageous because it can reliably notify the following vehicle of the presence of the vehicle.
Even if the light intensity of lamp 1 is increased, lamp 1 can be
Since the vehicle can be stored in a non-use position or stopped at an intermediate use position as shown by the broken line in FIG. 2, it is possible to avoid the inconvenience of causing glare to the driver of a following vehicle during normal driving.

Next, the rotation drive device of the lamp 1 and the adjustment means for adjusting its rotation position will be explained.The adjustment means in this example is as follows: (1) The driver can freely adjust the lamp 1 to the desired rotation position. (2) When the driver shifts the shift lever (not shown) of the transmission to reverse, since it is highly necessary to visually check the rear when the vehicle is reversing,
In conjunction with this, the lamp is automatically raised to the most used position and the light bulb 3 is turned on.

In FIGS. 2 to 4, an electromagnetic brake 16 and a motor 1 as described above are provided on the vehicle body portion 10b facing the wall surface 15 on the vehicle center side of the lamp housing 2.
7 are integrally fixedly supported (see also FIG. 6). A rotation link 1 is attached to the output shaft 18 of the motor 17.
9 is fixed at one end, and a spherical bearing 20 is fixed at the other end of the link 19, and a wall surface 15 of the housing 2.
Each end of the connecting link 22 is pivotally connected to a spherical bearing 21 that protrudes from the spherical bearing 21 .

Further, in the aforementioned vehicle body portion 10b, there are shown in FIGS.
As shown in FIG.
2 assumes the posture shown in FIG. 5a, and the rotation link 19
keeps the first limit switch 23 on. The motor 17 operates, and the rotation link 19 moves to the shaft 1.
8 in the direction indicated by arrow C in FIGS.
1 in the direction of arrow A (Figures 2 and 5a)
The above-mentioned operation can be obtained by rotating the When lamp 1 leaves the non-use position, first limit switch 2
3 is also turned off. When the lamp 1 reaches its extreme use position, each link 19, 22 takes the position shown in FIG. 5b, and the rotary link 19 turns on the second limit switch 24. By reversing the motor 17, the lamp 1 is rotated and stored from the extreme use position to the non-use position.

When the lamp 1 is in the non-use position, the first limit switch 23 is turned on as described above.
6, the first relay 26 is actuated and the normally closed switch 25 of the relay 26, which is normally kept closed, opens as shown by the broken line, and the light bulb 3 of the lamp 1 is opened as shown by the broken line. The electricity from the battery 27 is cut off, and the light bulb 3 remains off. Lamp 1 begins to rotate from the non-use position, and
When the limit switch 23 is turned off and takes the position shown by the solid line in FIG. 6, the operation of the first relay 26 is cut off, and the normally closed switch 25 is closed as shown by the solid line.
The light bulb 3 is connected to a battery 27 and lights up.
Thus, when the lamp is in the non-use position, the lamp 1 is turned off, and when the lamp 1 is rotated to the use position, it is turned on.

When the driver puts the shift lever into reverse, the shift lever interlock switch 28 shown in FIG. 6 is switched to the contact point D as shown by the solid line due to the operation of this lever. At this time, if the lamp 1 occupies a position other than the extreme use position, the second limit switch 24 is turned off and is in the position shown by the solid line in FIG. 6, so the second relay 29 is not activated and The normally closed switch 30 closes the circuit as shown by the solid line in FIG. Therefore, the voltage of the battery 27 is supplied to the forward rotation terminal 31a of the motor forward/reverse control circuit 31, and the motor 17 rotates forward.
At the same time, the electromagnetic brake 16 is also energized, and the braking action of the output shaft 18 by the brake is released. Therefore, the lamp 1 rotates in the direction of the arrow A in FIG. 2, and when it reaches the extreme use position, the second limit switch 24 is turned on. Therefore, the second limit switch 24 is in the state shown by the broken line in FIG.
The second relay 29 operates and its normally closed switch 30
opens as shown by the broken line, cutting off the power to the motor 17 and stopping the lamp 1. At this time, the power supply to the electromagnetic brake 16 is also cut off, the output shaft 18 is fixed by the braking action of the brake 16, and the lamp 1 is locked at the extreme use position. In this way, when the driver switches the shift lever to reverse, the lamp 1 automatically operates to the most used position, and the bulb 3 lights up to illuminate the rear.
The driver can easily back up the car while keeping a clear view of the rear.

When the shift lever is switched to a position other than reverse, the shift lever interlocking switch 28 is switched to the contact point E as shown by the broken line in FIG. For example, since the first limit switch 23 is turned off, the normally closed switch 33 of the third relay 32 remains closed as shown by the solid line in FIG. 31 and is supplied to the reverse rotation terminal 31b of the motor 17.
is reversed. At the same time, the electromagnetic brake 16 is also energized, and the braking action of the output shaft 18 is released. This causes the lamp 1 to rotate in the direction of arrow B in FIG.
When the lamp 1 reaches the non-use position, the first limit switch 23 is turned on, the third relay 32 is activated, and the normally closed switch 33 is opened as shown by the broken line, and the motor 17 is stopped and the electromagnetic brake is activated. 16 is also cut off, and the output shaft 18 is locked by this brake 16.

35 and 36 in FIG. 6 are diodes for blocking reverse voltage.

On the other hand, the driver's seat or its vicinity, such as the instrument panel (not shown)
A manual switch 34, shown in FIG. 6, is attached thereto, and this switch 34 normally occupies the inoperative position indicated by the solid line G. In this state, the lamp 1 can be operated in conjunction with the shift lever described above without any problem.

If the driver wants to use lamp 1 regardless of shift lever operation, use manual switch 34.
, and switch it to contact F, for example, as shown by the chain line. At this time, if the lamp 1 occupies a position other than the extreme use position, the second limit switch 2
4 is off, and the normally closed switch 30 of the second relay 29 is closed as shown by the solid line, so the voltage of the battery 27 is supplied to the electromagnetic brake 16 and the forward rotation terminal 31a of the control circuit 31, and the lamp 1 rotates in the direction of arrow A in FIG. When the lamp 1 reaches its extreme use position, the lamp 1 automatically stops and is locked by the electromagnetic brake 16 in the same way as when operating in conjunction with the shift lever.

Conversely, when the manual switch 34 is switched to contact H as shown by the broken line, the locking action by the electromagnetic brake 16 is released, and the motor 17 is reversed to rotate the lamp 1.
rotates toward the non-use position, and when it reaches the non-use position, it automatically stops and is locked by the electromagnetic brake 16.

When lamp 1 is rotating in the intermediate use position,
If the manual switch 34 is switched from the contact point F or H to the non-operating position G, the electromagnetic brake 16 and the motor 1
The power supply to lamp 7 is cut off, motor 17 is stopped, lamp 1 is stopped at its intermediate use position, and is locked in this position by electromagnetic brake 16. In this manner, by operating the manual switch 34, the lamp 1 can be brought to a desired rotational position for use or storage.

Effects According to the present invention, the rear of a car can be effectively illuminated.
