  However, in the above-described light-emitting roadway device disclosed in Patent Document 1, Patent Document 2, etc., in order to store daytime solar energy as electric energy, a large-capacity storage battery or capacitor is always required. The number of parts increases, and the apparatus becomes large and expensive.

  In addition, these devices cannot be used for light-emitting roadside devices because the sunlight does not reach and cannot be sufficiently photoelectrically converted even in daylight on dark roads, intersections, and tunnels.

  Furthermore, these devices have means capable of communicating necessary information such as traffic information and road information of the area toward the traveling vehicle simply by calling attention to the driver and passengers. Absent.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and provide a road fence having a simple and inexpensive structure that photoelectrically converts light from a traveling vehicle and emits light with its electric energy. Furthermore, the present invention provides a roadway having a structure capable of transmitting and receiving radio waves and ultrasonic waves using photoelectrically converted electric energy.

  A first aspect of the present invention is a roadway provided with a light emitting surface that emits light that is installed on a road and its surroundings and that performs light guidance and display of an outside line, and the headlight on which the traveling vehicle lights up The present invention relates to a light-emitting roadway having an electronic circuit including an element capable of photoelectric conversion by receiving light such as a fog lamp and light emitting means for emitting light toward the traveling vehicle by its electric energy.

  A second invention relates to a light-emitting roadway, wherein the light-emitting means according to the first invention is a light-emitting element of a light-emitting diode or a laser diode, and optical communication can be performed by modulating the light emission of the light-emitting element.

  A third invention relates to a light-emitting roadway according to the first invention, characterized by having an electronic circuit capable of transmitting and receiving radio waves or ultrasonic waves by photoelectrically converted electric power.

  The present invention is an inexpensive and simple light-emitting road fence device that can sufficiently accommodate storage batteries and capacitors with a small capacity or need to be supplied with electricity from the outside both in the daytime and in dimly lit roads and tunnels. No installation is required and installation is easy.

  Furthermore, according to the present invention, light communication can be easily performed by applying light modulation by using a light emitting diode (LED) or a laser diode (LD) as a light emitting element, and wireless communication using radio waves or ultrasonic waves is also possible. As a result, necessary information such as traffic information and road information can be communicated to the traveling vehicle. In addition, by transmitting the light-modulated signal, radio wave, and ultrasonic signal to a sign that can display the latest information installed in the vicinity of the light-emitting roadway, the latest necessary traffic information, road information, etc. It can also be used as a trigger to display only when the vehicle is traveling.

  The operation of the light-emitting roadway according to the present invention will be described below with reference to FIG. 1 is a road fence, 2 is a solar cell as a photoelectric conversion element, and 3 is an LED as a light emitting element. In addition, since FIG. 1 is installed in the center of the intersection, solar cells and LEDs are attached in four directions, but this is necessary depending on the road conditions such as road edges, center lines, T roads, and 5 roads. May be attached in the direction. Moreover, it is not necessary to limit to this shape, What is necessary is just the structure which can light-emit in order to alert a driver and a passenger of a running vehicle immediately by photoelectrically converting light from a headlight, a fog lamp, etc. of a running vehicle. .

  When driving in tunnels or at night, it is mandatory to turn on the headlights. In addition, in the mountainous areas where the depression and vegetation overgrown and the roads in the foggy section are not popular, headlights and fog lights are often lit even during the daytime to prevent danger.

  If the headlight or fog lamp of the traveling vehicle hits the solar cell 2 of the light-emitting road fence of the present invention installed on the road described above, the light energy is converted into electric energy, and the LED 3 such as red light is immediately emitted. Call attention to the driver and passengers of the traveling vehicle. When the vehicle moves and the light no longer illuminates the light-emitting road fence of the present invention, it is immediately turned off because there is no need to call attention. Further, even when the vehicle is not running, the light emitting roadside device of the present invention does not operate and remains unlit because no alert is required.

  In addition, the optical communication function can be achieved by storing nearby fixed road information (steep curve caution, downhill caution, etc.) in an IC or magnetic storage device added to the light emitting roadside device of the present invention in advance. By transmitting this information to the traveling vehicle having the light signal modulated from the light-emitting roadway device of the present invention, the traveling vehicle can also receive the road information (not shown).

  Furthermore, by transmitting these fixed road information by radio waves and ultrasonic waves from the light emitting roadside device of the present invention to a traveling vehicle having radio wave and ultrasonic wireless communication functions, the traveling vehicle receives the road information. It is also possible to do this (not shown).

  Also, by transmitting electrical signals, radio waves, and ultrasonic waves to signs that can display the latest information installed in the vicinity of the light-emitting roadside by using electrical energy obtained by receiving light from headlights, fog lights, etc. of traveling vehicles Also, it becomes possible to use the latest necessary traffic information (accidents and traffic jams), road information (under construction), etc. as a trigger (not shown) that is displayed only when the traveling vehicle is traveling.

  Since the light-emitting roadside device of the present invention does not have a large-capacity storage battery or capacitor, it immediately turns off when photoelectric conversion energy is not supplied. Since photoelectric conversion can be performed, light can be sufficiently emitted while the driver and passengers need to be alerted. In addition, the light-emitting roadway of the present invention may be provided with a reflector around the light-emitting element 3 to efficiently irradiate light in the target direction. In addition, the light emission may be blinked in order to improve alerting. Furthermore, since transmission / reception of radio waves and ultrasonic waves requires less power, the photoelectric conversion energy can be used sufficiently.

  In addition to the solar cell 2 as a photoelectric conversion element and the LED 3 as a light emitting element, the components of the present invention include electronic components such as necessary resistors, smoothing capacitors, radio wave or ultrasonic transmission / reception circuits, and ICs. It can be housed in a fence and can be affixed to the necessary locations on the road with an adhesive or the like, so installation work is unnecessary. In addition, since no external power supply is required, no electrical work is required.

  The present invention can be applied to all devices that use solar cells, such as nightlights and crime prevention lights, and control devices that want to be electrically controlled only when necessary.

  By making the light emitting element of the light-emitting roadside of the present invention LED or LD, it becomes possible to easily perform optical communication by light modulation, PR of nearby shops, evacuation information at the time of disaster, emergency information, etc. Can be sent to the traveling vehicle. In addition, by using radio communication using radio waves or ultrasonic waves, information can be transmitted to the traveling vehicle such as PR of nearby shops, evacuation information at the time of disaster occurrence, emergency information, and the like, as in optical communication.

  In addition, by sending the light, radio wave, and ultrasonic signals described above to the signs in the vicinity of the light-emitting roadside of the present invention, the latest PR for nearby shops, evacuation information at the time of disaster, emergency information, etc. It can also be used as a trigger to display.
