Abstract

PROBLEM TO BE SOLVED: To facilitate attachment and detachment with a min. space and to make arbitrary display by logically flickering spot light sources according to the moving quantity of a moving body. SOLUTION: This moving type display is composed of rods at least internally mounted with plural pieces of spot light sources in a longitudinal direction, fixtures for perpendicularly mounting these rods in the moving direction of the moving body and a control circuit for independently driving one spot light source of the rods. The spot light sources are locally flickered according to moving quantity of the moving body. More specifically, LEDs 4 lined up to constitute an array in resin pipes 3 which are hermetically closed at the top surfaces and allow the transmission of light are individually wired and are electrically connected to a control substrate 2. Fixtures 1 are fixed to the moving body. The respective LEDs 4 are changed over at every specified period from 0.01 second to 0.3 second according to the light emission procedures programmed by the control substrate 2 when a DC power source is supplied, by which a series of display contents are expressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accessory device for automobiles, motorcycles and the like.

[0002]

2. Description of the Related Art In order to transmit a display content drawn on a plane from a moving body such as an automobile to a passerby, etc., a unique plane for displaying is required. Often limited to places.

In particular, in the case of a small car or the like, the larger the display area is, the more blind the driver is likely to be, and the risk of peeling off due to the influence of air resistance during traveling may be a serious safety problem. It is considered that conventional large-sized displays are not possible for motorcycles due to road traffic laws and safety.

Further, when it is desired to easily change the display contents, it is general to either mechanically move the display surface with a motor or the like or electrically drive the dot matrix element. Both of them are expensive and complicated, and also have problems in mounting.

[0005]

The problems to be solved by the invention are that they require a proper plane for large-scale display, and there are problems such as mounting problems, safety problems, and instantaneous change of display contents. To be

[0006]

[Means for Solving the Problems] By utilizing a stable horizontal moving body such as an automobile and an afterimage phenomenon occurring in the retina of a human being, it is possible to perform vertical movement in a moving direction without attaching a large-sized display as in the past. By attaching a rod in which various point light sources are arranged to a moving body and controlling the point light source, it is possible to easily display any character or the like.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Each point light source group in the rod mounted perpendicularly to the moving direction of a moving body blinks under control. As the moving body moves horizontally, it is temporarily stored as an afterimage of point light sources arranged vertically on the retina of a human who is directly looking at it statically, and the point light source group that changes while moving one after another is It is possible to recognize the display contents by forming a dot matrix in a retina shape.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A structural explanation will be given with reference to FIG. The point light source is defined to mean both one in which one element emits light by itself and one in which one element shields light in front of the backlight. In the embodiment, description will be made using an LED which is one type of point light source. Further, the term "vertical" used to describe that the rod is vertically attached in the moving direction is regarded as a practical range if it is within ± 40 degrees from the true vertical.

The LEDs 4 arranged in rows are individually wired in a resin pipe 3 having a sealed top surface and capable of transmitting light, and are electrically connected to the control board 2. Reference numeral 1 is a fixture for fixing to a moving body. Therefore, by supplying DC power, each LED 4 is switched at a constant time of 0.01 seconds to 0.3 seconds in accordance with the light emission procedure programmed in the control board 2 to express a series of display contents. The subject of the present invention is the configuration of the display device, and description of the electronic and mechanical systems is omitted.

In carrying out the present invention, it is also conceivable to include an electric conductor in the longitudinal direction in the inside or on the surface of the rod so as to have a function of a vertical antenna for radio such as a mobile telephone.

Further, by arranging the LEDs on the front and back sides of the board, the sidewalks on both sides can be seen well and the display contents can be changed between the back and front.

Alternatively, the display content may be changed by transferring character data from the outside and rewriting or switching the memory.

Further, a speed sensor or an acceleration sensor may be used to instantly display a measured value or the like, and the blinking timing may be set based on the measured value.

Further, by arranging a plurality of the displays of the present invention in parallel, when one image cannot display many characters due to a short afterimage time or a display effect utilizing the display effect caused by the interference on the afterimages of the plurality of images is displayed. Application of vessels is also possible.

[0015]

[Effects of the Invention] When a moving body equipped with the display device of the present invention is run at night, the light emitting groups of vertically aligned LEDs form a display plane in the air, and produce beautiful illumination utilizing the afterimage phenomenon of the naked eye.

Since this indicator has a rod-like shape, it has little air resistance due to wind pressure and can be safely driven even when it is mounted on an automobile or the like without hindering the driver's view. Also,
It is also possible to call attention to the pedestrian by displaying the speed and the amount of acceleration / deceleration. This afterimage phenomenon is fixed vertically to the moving body, and produces the clearest display when running at night.
