DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction indicator for indicating the turning direction of a vehicle by blinking a group of light emitters provided on both the left and right sides of the front or rear surface of the vehicle.

[0002]

2. Description of the Related Art A plurality of light emitters are arranged adjacent to each other in the left-right direction, and the light emitters are sequentially turned on and off from the inner one to the outer one in the vehicle width direction to thereby reduce the light source. A direction indicator for displaying a turning direction of a vehicle as a moving direction is known from Japanese Utility Model Publication No. 7-10953.

[0003] Light-emitting bodies which also serve as a turn signal indicator and an emergency blinking indicator are arranged on both left and right sides of the vehicle, respectively.
When the emergency flashing switch is turned on and the left and right light emitters are flashing at the same time, if you forget to turn off the emergency flashing switch and turn on the direction indicating switch, the function as a direction indicator will be given priority to one of the left and right. The one that causes only the light emitter to blink is known from JP-A-8-34284.

[0004]

By the way, in the device described in Japanese Utility Model Publication No. 7-10953, the number of parts increases because each light-emitting group is composed of three or more light-emitting members. Needless to say, there is a problem that the flashing control thereof is complicated. Further, Japanese Patent Application Laid-Open No. 8-34
In the device described in Japanese Patent No. 284, the function of the emergency blinking indicator is canceled and only the function of the direction indicator is exhibited when the emergency blinking switch and the direction indicating switch are simultaneously turned on. In the case where the vehicle stops while moving in either direction on the road, there is a problem that a stop signal and a direction instruction signal cannot be sent to the following vehicle at the same time.

The present invention has been made in view of the above circumstances, and provides a highly visible direction indication with a minimum number of light emitters, and at the same time, has both the function of an emergency blinking display and the function of a direction indicator. The purpose is to:

[0006]

In order to achieve the above object, a direction indicator according to the present invention comprises a left and right pair of right and left light emitters, each of which is composed of a first light emitter and a second light emitter. Are arranged on the front or rear surface of the vehicle, and the second illuminant located outside each illuminant group has a larger lateral dimension than the first illuminant located inside. When a direction is indicated by one of the light-emitting groups, the second light-emitting body is turned on with a predetermined time delay after the first light-emitting body is turned on.

According to the above configuration, when the direction is indicated by one of the right and left light emitting groups, the first light emitting body located inside the vehicle width direction is first turned on, and after a predetermined time elapses, the first light emitting body is located outside the vehicle width direction. Since the second illuminant is turned on and both illuminants are turned on at the same time, the first illuminant is first turned on to draw human visual attention, and then the second illuminant having a large lateral dimension By lighting the body with a delay of a predetermined time, it is possible to cause a delay in visual information signal processing in the human brain and cause an illusion that light moves in the left-right direction.
As a result, the light of the second illuminant seems to flow out in the left-right direction from the place where the first illuminant is turned on. Function can be enhanced.

The predetermined time is from 1/10 sec to 1/1.
It can be set arbitrarily in the range of 000 sec.
About 00 sec is appropriate.

[0009] The direction indicator according to claim 2 is
In addition to the configuration of claim 1, the pair of left and right light emitters also serves as an emergency blinking display, and when performing emergency blinking display and direction indication simultaneously, one of the light emitter groups is the first light emitter and the second light emitter. Two illuminants are turned on simultaneously and the other illuminant group is the first
It is characterized in that the second light emitter is turned on after a lapse of a predetermined time after the light emitter is turned on.

According to the above configuration, when the emergency blinking display and the direction instruction are simultaneously performed, the first and second light emitters of the illuminating body group on which the direction instruction is not performed are simultaneously lit, and the luminous body on which the direction instruction is performed is not performed. In the luminous body group, the first and second luminous bodies are turned on with a time difference. Therefore, the function of the emergency blinking indicator can be exhibited by blinking both the right and left illuminant groups, and the left and right illuminant groups are illuminated with a time difference, so that the light is left and right. The function of the direction indicator can be exhibited by causing an illusion of moving in the direction. In this way, the function of the emergency blinking indicator and the function of the direction indicator are compatible, so that the driver's intention can be accurately communicated when the vehicle stops while leaning left and right.

Next, the operation of the embodiment of the present invention will be described.

FIG. 2 explains the operation when the right direction switch SW _R is turned on when the vehicle turns right. (1) Right direction switch SW _R is OF
This shows the state when the camera is in the F state. At this time, the first light emitters L _L1 and L _R1 and the second light emitters L _L2 and L _R2 are all turned off. ON the right direction switch SW _R Then, flashing current generating circuit lighting clusters flashing current right from C ₁ S _R

This makes it possible to accurately communicate the driver's intention to stop the vehicle while moving it to the left. Incidentally, when ON simultaneously very blinking switch SW _H and the right direction indication switch SW _R in order to stop while asked the car to the right, with the left side of the lighting cluster S _L blink simultaneously, the right lighting clusters by S _R flashes with a time difference, it is possible to achieve both the extremely blinking display function and a direction indication function.

Although the embodiment of the present invention has been described in detail, various design changes can be made in the present invention without departing from the gist thereof.

For example, in the embodiment, the light emitter groups S _L and S _R are provided on the rear surface of the vehicle, but they may be provided on the front surface of the vehicle or on both front and rear surfaces. Further, the first light emitters L _L1 and L _R1 and the second light emitters L _L2 and L _R2 can be constituted by other light emitters such as light emitting diodes instead of being constituted by lamps.

[0030]

As described above, according to the first aspect of the present invention, when a direction is indicated by one of the left and right light emitting groups, the first light emitting body located inside the vehicle width direction is first turned on. ,
After the elapse of a predetermined time, the second
Since the light emitters are turned on and both light emitters are turned on at the same time, the first light emitter is first turned on to draw human visual attention, and then the second light emitter having a large left-right dimension is determined. By turning on the lamp with a time delay, it is possible to cause a delay in visual information signal processing in the human brain and cause an illusion that light moves in the left-right direction. As a result, the light of the second illuminant seems to flow out in the left-right direction from the place where the first illuminant is turned on. Function can be enhanced.

According to the direction indicator of the second aspect, when the emergency blinking display and the direction instruction are simultaneously performed, the first and second light emitters on the side not performing the direction instruction are simultaneously operated. The first and second luminous bodies of the luminous body group on the side that performs the direction instruction are lit with a time difference. Therefore,
The function of the emergency blinking indicator can be exerted by blinking both the right and left illuminant groups, and light is emitted in the left and right direction by illuminating only one of the left and right illuminant groups with a time difference. The function of the direction indicator can be exerted by causing an illusion of movement. In this way, the function of the emergency blinking indicator and the function of the direction indicator are compatible, so that the driver's intention can be accurately communicated when the vehicle stops while leaning left and right.
