Description

  The present invention relates to a safety marking device installed at a place where children often use such as a dangerous place without a traffic light, a pedestrian crossing, or a kindergarten or school entrance / exit.

  Conventional marking devices are often invisible or difficult to see at night or in dim light. For this reason, a reflective tape is attached to the outline of the sign, or a solar system is installed to make a light-emitting diode. Some of them have problems such as being unable to know their existence without the irradiation of the vehicle, and reducing their attention if they are constantly lit continuously. For this reason, Japanese Patent Application Laid-Open No. 6-314398 has been proposed as a display for raising the driver's attention, prompting the driver's attention, and preventing an accident from occurring. This structure has a solar system consisting of a mechanism that converts solar energy into electrical energy, a battery that stores electrical energy, and a sensor that has a switch mechanism that is energized when below a certain illuminance. It has a detachable casing and a number of light emitting diodes arranged on the surface of the casing, and is electrically connected to the light emitting diodes and the solar system. In addition, it is disclosed that the light-emitting diodes are intermittently blinked to further alert the driver.

However, Japanese Patent Laid-Open No. 6-314398 is used for a curved mirror, various kinds of guide signs, etc. In the curved mirror, a sub-marker is attached under the curve mirror, characters are displayed on the sub-marker, and an arrow is displayed. Since there was a built-in light emitting diode, there was a planar change, but there was no three-dimensional change. Therefore, if this is installed near a pedestrian crossing without a traffic light or near the entrance of a kindergarten or school, the light emitting diode will be more noticeable than the conventional one, especially when crossing a pedestrian crossing at night. Because there are many places where there are many electric signboards, there was a possibility that the driver's attention could not be drawn enough only by flashing the light. In addition, if the light emitting diodes are continuously turned on or blinking, there is a risk of insufficient charging before the sun goes down. As a result, there is a concern that the light emitting diodes will not be turned on or blinking, and the brightness decreases and becomes noticeable. The current situation is that there is a risk that it will disappear, and personal injury cannot be prevented. Furthermore, if it is constantly lit or flashing, it can be seen very conspicuously and can attract the driver's attention, but it is very conspicuous, so it is easy to remember its installation location etc., especially traveling well in that installation location At present, the driver's attention has been irritated and the attention has been distracted, and the effect has not been improved.
