Incidentally, the LED 22 of each of the above-mentioned embodiments
Based on the visibility curve based on the known Purkinje effect, the light intensity value can be set to an intermediate value between the light intensity at daytime and the light intensity at night, for example, a value corresponding to the light intensity at dusk. For this reason, it is possible to incorporate a sensor for determining day and night. In particular, it is preferable that the detection of the light amount is configured to detect the light amount outside the vehicle for the purpose of improving the visibility of the abnormal approach warning display device located outside the vehicle.

When such a configuration is added, the light emission color of the abnormal proximity warning display device can be automatically set to blue or red according to the difference in light amount such as day and night. That is, when the amount of light is low, such as at night or in a tunnel, the abnormal proximity warning display device is set to emit light in a bluish color that is considered to be a color that is easily visible due to the Purkinje effect, while daytime,
When the amount of light is large, the abnormal approach warning display device is set to emit light in a reddish color which is a color that is easily visible due to the Purkinje effect. As a result, the light emission color of the abnormal proximity warning display device can be set to a preferable color according to the light amount as the external environment, and the driver can always visually recognize the abnormal proximity warning display device regardless of the change in the light amount. be able to.

Then, the distance sensor 10 of each of the above embodiments
Can have one or more distance sensors 10 arranged to detect obstacles in front of and on the sides of the vehicle body AC. Also, a plurality of sensors are combined to form the corner pole body 1
It is also possible to provide separately. The distance sensor 21 disposed inside the corner pole body 1 is one of an ultrasonic sensor, an optical sensor, and another proximity switch.
And a sensor having characteristics matching the distance to be detected can be used, and the reliability of detection can be improved.

Further, in each of the above-mentioned embodiments, the LED 22 is made up of three color LEDs 22R, 22G, 22 of red, green and blue.
However, as long as it is possible to generate a plurality of colors necessary for giving a meaning such as a warning using the LEDs 22 of different colors, the LEDs 22R, 22G,
It is not necessary to use 22B, and it is possible to use any one of these three colors. In this case as well, although the types of colors that can emit light are limited, similar effects can be achieved. However, when the LEDs 22R, 22G, and 22B of three colors are used, all colors can be generated, and the effect of widening the range of use can be obtained.

Furthermore, the corner pole body 1 for carrying out the present invention may use a warning for one specific use as a display as in the above-mentioned embodiments, but when carrying out the present invention, Can also be used as a warning display common to multiple applications.

The corner pole body 1 of this embodiment
Has been described in the case of expanding and contracting in three stages, but in the case of implementing the present invention, it can be used for one that expands and contracts in two or more stages, Can also be used.
