Abstract

PURPOSE:To display characters and graphics or the like in a space made by the signal lamp shaked repeatedly by turning on and off the light by means of each light emitting element on a head shake bar according to a time schedule depends on the lapse of time. CONSTITUTION:One direction side of a signal lamp main body 1 is opened. Light emission diodes 2 are arranged in columns and the light axis of the diode 2 is set vertically to the opening surface. The timing to form the characters and graphics by turning on and off the light emission diode 2 is under the control of a microcomputer. In short, the diode 2 in columns is turned on and off by a turning ON/OFF control section. On the other hand, the timing information of characters and graphics to be formed is stored in a ROM in advance and taken out properly by a CPU. In this case, the reference point of a turning ON/OFF timing is set to the turning point in the shaking direction and the point is detected by a movement direction sensor. On the other hand, a timer mechanism is started by the detection of the reference point by the movement direction sensor and transmits the time information to the CPU.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand signal light device capable of displaying characters in a space.

[0002]

2. Description of the Related Art A hand waving signal lamp is used for traffic control and the like, but the conventional hand waving signal lamp is simply a handshake part to which a light emitting part is connected.

[0003]

In the above case, the meaning of the signal is transmitted depending on the color of the light, the direction of the signal lamp, etc., but of course it is not universally determined and there is a difficulty in communication.

The present invention takes advantage of the physiological afterimage phenomenon of the naked eye to solve these problems by displaying characters, figures and the like in a space where the signal light device is repeatedly shaken by hand to improve communication of contents. The purpose is to provide a container.

[0005]

In order to achieve the above object, in a signal lamp according to the present invention, light source bodies having a center line in a direction perpendicular to a waving surface are arranged in rows on a rod-shaped lamp body. Then, by controlling the blinking state of this, characters and figures are displayed on the gesturing surface. When the same surface is swung so that the hand shaking speed is substantially constant and the turning point at the turning direction is used as the reference point, the elapsed time from the reference point is a distance from the same point. The locus of the light source group arranged in the hand gesture along the hand gesture is a concentric arc with a long radius.

Therefore, if the light source bodies are made to blink on the locus according to the program, they are approximately equivalent to the luminous body matrix.

The reference point is the turning point of the hand gesture,
A moving direction sensor is used for this detection. Since the speed of hand shaking varies depending on the person who uses it, an acceleration sensor is provided as a countermeasure to adjust the speed of blinking according to the program.

[0008]

In this case, when the above-mentioned hand waving signal lamp is shaken up and down, the moving directions of the illuminators are reversed at the uppermost and lowermost points, so the moving direction sensor detects and this point becomes the reference point.

Starting from this point, the timer is started, and each light emitting element on the waving stick is turned on and turned off according to the time schedule based on the elapsed time. This time schedule is designed so that each illuminator on the unidirectional axis in the illuminator matrix is in a blinking state. proceed.

Since the naked eye has a physiological afterimage characteristic, when the signal lamp is moved up and down at a constant speed, a luminous body matrix is present on the gesturing surface, and characters and figures are constructed by this. To be hoped for.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the drawings, an embodiment according to the present invention will be described. In FIG. 1, the signal lamp body 1 is open in one direction, and the light emitting diodes 2 are arranged in rows at this position. There is. The optical axis of the light emitting diode 2 is installed along the open surface. Light emitting diode 2
The number of characters depends on the characters and figures that compose them, but the minimum number that can be distinguished is required.

One end of the main body is a grasping portion 3 having a shape that is easy to grasp.

The timing for turning on the light emitting diode and forming a character or figure is controlled by a microcomputer. These relationships are shown in FIG. In this, the light emitting diodes 2 arranged in a row are turned on and off by the blinking control unit 31. On the other hand, the timing information of the characters and figures to be formed is stored in advance in the ROM 33 and is taken out by the CPU at appropriate times. The type can be selected by the input switch 32. The reference point of the blinking timing is the turning point of the swing direction, and this point is detected by the movement direction sensor 36.
On the other hand, the timer mechanism 37 is activated by detection of the reference point by the movement direction sensor 36, and sends time information to the CPU.

The above information is exchanged via the I / O unit, but using a chip integrated in one chip excluding the movement direction sensor 36 and the timer mechanism 37 is suitable for miniaturization.

In the flow chart of FIG. 4, the signal lamp is moved up and down as shown in FIG. 2, and when the swing direction changes, this becomes the reference point and the timer mechanism is activated. Since the position change is related to the time change, each light emitting diode is turned on after a predetermined time elapses. This is repeated until the final point according to the timing schedule for composing characters and the like.

If the speed of the hand gesture has a large difference from the standard, the characters and the like that expand and contract will expand and contract. Therefore, the transition speed of the blinking timing schedule is feedback-controlled corresponding to the hand gesture speed, and this is processed. Since the locus of the lamp corresponding to the hand movement is an arc, the arc velocity is proportional to the acceleration toward the center of the circle, that is, the center force of the circle. An example of the acceleration sensor is shown in FIG. In the same figure, the phenomenon that the iron core of the oscillator moves and the frequency changes depending on the value of the acceleration is used. Further, by arranging this so that the acceleration direction corresponds to the movement direction of the hand swing bar, it can be used as the hand swing bar movement direction sensor.

In this embodiment, a light emitting diode is used as a light emitting body, but the same effect can be obtained with other light emitting bodies.

[0018]

[Effect] When a signal light as described is used, unlike the operation of simply moving up and down a signal light such as a red lamp, a message such as "stop" or "under construction" is added to the air at the same time. Therefore, the meaning of communication can be properly displayed to the target person, which is particularly effective for traffic control.
