Abstract

PROBLEM TO BE SOLVED: To provide a pedestrian crossing lighting device capable of making drivers driving their cars toward a pedestrian crossing recognize that there are pedestrians, bicycles, etc., going across the pedestrian crossing and, at the same time, calling their attention to them which are crossing the pedestrian crossing. SOLUTION: A detection sensor 2 detects pedestrians, bicycles, etc., going across a pedestrian crossing 1 in the night, and a lighting lamp 3 is turned on for a specific time based on the detection signal to irradiate the surface of the pedestrian crossing 1. Since the lighting lamp 3 illuminates the surface of the pedestrian crossing 1 only when the pedestrians, bicycles, etc., are crossing the pedestrian crossing 1, drivers driving their cars toward the pedestrian crossing 1 can easily recognize that there are pedestrians, etc., on the crossing, their attention can be called to effectively prevent accidents on the pedestrian crossing 1, and since the lighting lamp is not turned on when there is no pedestrian, bicycle, etc., on the crossing, economical loss is also reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to promote safe crossing for pedestrians and cyclists trying to cross a pedestrian crossing at night, and to alert a vehicle traveling toward the pedestrian crossing. The present invention relates to a pedestrian crossing lighting device that can be used.

[0002]

2. Description of the Related Art In the past, especially on pedestrian crossings without traffic light equipment, so-called internally illuminated pedestrian crossing signs having a built-in lighting device are generally installed. By illuminating this lighting device throughout the night, the vehicle traveling toward the nighttime crosswalk is made aware of the presence of the crosswalk.

[0003]

However, although the above-mentioned illuminated pedestrian crossing sign makes it possible to recognize the existence of a pedestrian crossing, the illuminated pedestrian crossing is lit all night regardless of the presence of pedestrians crossing. However, for drivers who are familiar with the pedestrian crossing, it is scarce to call attention.Although the surrounding lighting system is installed to illuminate the pedestrian crossing, the pedestrian crossing is dim to the driver. However, the illuminance is not always sufficient to recognize the presence of a pedestrian or the like who is crossing. In particular, when an oncoming vehicle is present, a pedestrian or the like may be momentarily invisible due to a so-called evaporation phenomenon. It is sufficient to increase the illuminance of the lighting equipment, but there is an economic loss if the illuminance is kept increased even when there are no pedestrians or the like. Therefore, although there is an internally illuminated pedestrian crossing sign, accidents at the pedestrian crossing are always ongoing.

Accordingly, the present invention solves the above-mentioned problems,
For the driver traveling to the crosswalk,
It is an object of the present invention to provide a pedestrian crossing illumination device that can recognize the presence of a pedestrian, a bicycle, or the like that is crossing a pedestrian crossing, and can alert the user.

[0005]

In order to achieve the above object, the present invention has the following arrangement. That is, the pedestrian crossing illumination device according to the present invention includes a detection sensor that detects a pedestrian or a bicycle that is trying to cross the pedestrian crossing at night, an illuminator that lights up and illuminates the pedestrian crossing, and a detection signal of the detection sensor. And a control unit for turning on the illumination lamp for a predetermined time based on the control information.

According to the present invention, the detection sensor detects the presence of a pedestrian, bicycle, or the like trying to cross the pedestrian crossing at night, and turns on the illuminating lamp for a predetermined time based on the detection signal to change the pedestrian crossing surface. By illuminating, only when there are pedestrians or bicycles trying to cross the pedestrian crossing, these lights will illuminate the pedestrian crossing surface, so drivers traveling toward the pedestrian crossing will be It is easy to recognize the existence of such things as it is alerted, it is possible to effectively prevent accidents at pedestrian crossings, and it is turned off when there are no pedestrians or bicycles, so there is also economic loss. Be avoided.

[0007] The detection sensor for detecting a pedestrian or a bicycle in the present invention is not particularly limited as long as it detects the presence of a pedestrian or a bicycle in a predetermined area of a pedestrian crossing. However, a pyroelectric infrared sensor that can detect the presence of a pedestrian or the like by detecting a heat ray emitted from a pedestrian or the like is preferable, but an ultrasonic sensor that emits an ultrasonic wave and detects a reflected wave thereof or emits the ultrasonic wave. An optical sensor or the like including a light emitting element and a light receiving element that detect light by blocking light may be used. In order to operate this detection sensor only at night, a day / night detection sensor that detects day / night by using, for example, an electromotive force of a solar cell that changes according to the surrounding illuminance, a timer, and the like are used in combination.

As an illumination lamp, a halogen lamp having a high luminance is generally used, but it is not particularly limited. Further, the control unit receives the detection signal of the detection sensor, supplies power from the power supply device to the illumination lamp based on the detection signal, and lights the illumination lamp for a predetermined time.
As a power supply device, a commercial power supply generally used for existing lighting equipment is used in combination, but a solar cell may be used.

In the present invention, the illuminating lamp may be provided, for example, by erected a pillar at an end of the pedestrian crossing and individually attached to the pedestrian crossing. However, since a pedestrian crossing sign is generally installed on the pedestrian crossing, Attachment to the pedestrian crossing sign facilitates installation work.

In the present invention, when the detection sensors are provided on both sides of the pedestrian crossing, the detection signal of one of the detection sensors close to the control unit is transmitted to the control unit by wire, and the other detection sensor is connected to the control unit. If the detection signal of the sensor is wirelessly transmitted to the control unit, there is no wiring that crosses the pedestrian crossing, and wiring work between the detection sensor and the control unit becomes easy.

Further, in the present invention, if a voice generating device for generating a voice such as "Let's cross right and left" based on the detection signal of the detection sensor is provided, pedestrians and the like are also alerted. Is preferred.
