The pedestrian crossing illumination device 1A of the present invention is installed at one end of the pedestrian crossing 50.
Two types are set, a pedestrian crossing illumination device 1B (hereinafter, abbreviated as a device 1B) installed opposite to the other end of the pedestrian crossing 50 (hereinafter, abbreviated as a device 1A).

The only difference between the apparatus 1B and the apparatus 1A is the difference between the reception frequency of the reception circuit 20 and the transmission frequency of the transmission circuit 36. For example, the receiving circuit 2 of the device 1A
0 is set to the reception frequency f _2, the transmitting circuit 36 is set to the transmission frequency f _1. The receiving circuit 20 of the apparatus 1B is set to the reception frequency f _1, transmitting circuit 36 is set to the transmission frequency f _2. Then, both devices 1A, 1
Operation signals are mutually transmitted and received between B, and both are operated simultaneously according to a command from the control circuit 22 on one side.

The pedestrian crossing illumination device 1 configured as described above
A and 1B are installed on pillars 9 and 9 erected on sidewalks 51 and 51 at both ends of the crosswalk 50, respectively.

FIG. 5 shows the installation state, and the apparatus 1A
The illuminating lamps 26, 26 are located near the other end of the pedestrian crossing 50.
It is installed so as to irradiate the irradiated area 54a in the range of slightly over / 2. The human sensor 16 is fixed by setting a detection area 52a on a sidewalk 51 at one end of the pedestrian crossing 50, and the vehicle sensor 18 is fixed toward the vehicle arrival direction of the road on the side where the device 1A is installed.

As shown in FIG. 5, the apparatus 1B includes an irradiation area 54 having a little more than half the area near one end of the pedestrian crossing 50.
b. The human sensor 16
Is fixed by setting a detection area 52b on the sidewalk 51 on the other side of the crosswalk 50, and the vehicle sensor 18 is fixed toward the vehicle arrival direction on the installation side roadway. Therefore, the beam of light 56a emitted from the lighting lamps 26, 26 of the device 1A and the beam of light 56b emitted from the lighting lamps 26, 26 of the device 1B intersect at the center of the pedestrian crossing as shown in FIG. An area with a large amount of light is formed.

Next, the operation of the crosswalk lighting devices 1A and 1B will be described.

Each of the devices 1A and 1B charges the battery 12 with the electromotive force of the solar cell 10 during the daytime when the amount of solar radiation is large, and the day / night discrimination circuit 14 outputs the discrimination signal A of "daytime" to the control circuit 22.
Output to

When the pedestrian enters the detection area 52a to cross the pedestrian crossing 50, the human sensor 16 of the device 1A captures the far infrared rays emitted from the pedestrian and outputs a detection signal B. . In response to this, the control circuit 22 outputs the command signal c ₁ and the corresponding command signal d to the voice synthesis circuit 33 and the transmission circuit 36, respectively.

As a result, in the apparatus 1A, the voice synthesizing circuit 33 operates to output a caution message, and the speaker 34 outputs a voice saying "Let's look at the left and right well and cross over." The transmitting circuit 36 transmits from the antenna 37 a command signal d at the frequency f _1.

In the apparatus 1B, the radio wave of the frequency f ₁ is received by the receiving circuit 20 via the antenna 21, and the received signal D corresponding to the command signal d (corresponding to the command signal c ₁ ) is output to the control circuit 22. You. Then, the control circuit 22 outputs the instruction message c _{1 to} the voice synthesizing circuit 33 of the device 1B, and outputs the above-mentioned caution message voice from the speaker 34. Therefore, by detecting the device 1A on one side,
The devices 1A and 1B on both sides simultaneously perform the same operation.

When the human sensor 16 detects a pedestrian and outputs a detection signal B, and the vehicle sensor 18 captures far infrared rays emitted from the approaching vehicle 58 and outputs a detection signal C, The control circuit 22 outputs a command signal c ₂ ,
And a command signal d corresponding thereto,
And output to the transmission circuit 36. This allows the device 1A
Outputs a warning message voice saying “While approaching a vehicle!
6 transmitted from the antenna 37 a command signal d at the frequency f _1.

In the apparatus 1B, the radio wave of the frequency f ₁ is received by the receiving circuit 20, and a received signal D corresponding to the command signal d (corresponding to the command signal c ₂ ) is output to the control circuit 22. and it outputs the above-described warning message audio from the speaker 34 of the apparatus 1B as a command signal c _2.

When no pedestrian is detected in the detected area 52a (when the detection signal B is off), even if the vehicle 58 is approaching and the vehicle sensor 18 outputs the detection signal C, the control circuit No command signal is output from the terminal 22.

When the amount of solar radiation decreases and the electromotive voltage of the solar cell 10 falls below a certain voltage, the day / night discrimination circuit 14 outputs a “night” discrimination signal A to the control circuit 22. And the device 1
When the human sensor 16 of A detects a pedestrian in the detection area 52a, a detection signal B is output to the control circuit 22, and the control circuit 22 outputs the command signals a and b and the command signal d corresponding thereto to the illumination. It outputs to the lighting circuit 24, the warning flashing circuit 28, and the transmission circuit 36. As a result, the lighting circuit 24 turns on the lighting lights 26 and 26, and the lighting lights 26 and 26
is emitted to irradiate the irradiated area 54a. The warning flashing circuit 28 flashes the plurality of warning light emitters 30 and transmits a flashing sign to call attention to the driver of the vehicle 58 approaching the roadway on the near side. The transmitting circuit 36 transmits from the antenna 37 a command signal d at the frequency f _1.

In the apparatus 1B, a radio wave of the frequency f ₁ is generated by the receiving circuit 20, and a received signal D corresponding to the command signal d (corresponding to the command signals a and b) is output to the control circuit 22. The signals a and b are output to the illumination lighting circuit 24 and the warning blinking circuit 28 of the device 1B.

Then, the lighting lighting circuit 24 of the device 1B
The illumination lamps 26, 26 are turned on, and the illumination lamps 26, 26 emit light beams 56b to irradiate the irradiated area 54b. The light beam 56b intersects with the light beam 56a of the device 1A at the center of the pedestrian crossing 50, and forms a region with a large amount of light at the center to make the traverser clearly emerge. The warning flashing circuit 28 of the apparatus 1B flashes the warning light emitter 30 and transmits a flashing sign toward the other side of the road.

In the "night", the vehicle sensor 1
8 detects the vehicle 58 and outputs the detection signal C, the control circuit 22 does not output the corresponding command signal, and therefore,
The devices 1A and 1B respond only to the detection signal B and the reception signal D.

Regardless of “daytime” or “nighttime”, the device 1B on the opposite side detects the pedestrian or the vehicle 58 and the device 1A
Does not detect them, the subject of the action and the dependency are reversed from those described above. When both devices 1A and 1B simultaneously detect, they operate in parallel at the same time.

It should be noted that the present invention is not limited to the above description and examples of the drawings, and the embodiments thereof can be modified without departing from the technical idea of the present invention. For example, the device is configured by omitting the vehicle sensor 18,
The voice generating means 32 may output only one type of message.

The area to be illuminated by the illumination lamps 26, 26 may be formed by irradiating the entire pedestrian crossing with one device 1A. In this case, the other device 1B is set to irradiate the entire pedestrian crossing. Also device 1
The illuminating lights 26 and 26 of A and 1B may irradiate the area of almost half of the side of the pedestrian crossing near the device installation side, and may irradiate the entire pedestrian crossing.

Further, the pedestrian crossing illumination device of the present invention may be configured such that the receiving circuit 20 and the transmitting circuit 36 are omitted, and the pedestrian crossing lighting device operates independently on both sides of the pedestrian crossing. In this configuration, the illuminating lamp of one device is set to illuminate the entire pedestrian crossing.

[0058]

Since the pedestrian crossing illumination device of the present invention is configured as described above, when a pedestrian approaches the pedestrian crossing in the daytime, the pedestrian is alerted by voice, and the pedestrian crossing is illuminated at night. The pedestrian can be illuminated to alert the vehicle driver.

Further, the one provided with the vehicle sensor can switch the voice output to the pedestrian into a caution message and a warning message depending on the presence or absence of the approaching vehicle, thereby further alerting the pedestrian.

In the case where the light beam of the illuminating light of the pedestrian crossing lighting device and the light beam of the illuminating light of the pedestrian illuminating device provided opposite to each other are provided, By forming an area with a large amount of light in the center part, it is possible to make the traversing person clearly stand out.

Further, in the apparatus provided with the receiving circuit and the transmitting circuit, a pair of pedestrian crossing lighting devices provided at both ends of the pedestrian crossing operate in conjunction with each other to further draw attention to pedestrians and vehicle drivers. can do.

Further, since the illumination lamp, the warning illuminant, and the sensors are integrally formed and a commercial power supply is not used, the installation of the apparatus is easy and the underground wiring can be eliminated.
