Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road environment for displaying a road environment such as a pedestrian crossing warning and a rockfall warning, which is arranged above a road at a side edge portion of the road via a support pole or the like.

2. Description of the Related Art Conventionally, a pedestrian crossing has been installed on a road with a high traffic volume of automobiles and other vehicles to ensure the safety of pedestrians, and the position of the pedestrian crossing can be easily confirmed at night. In order to do this, an internally illuminated pedestrian crossing sign is placed above the pedestrian crossing to alert the driver of the vehicle. However, in this type of internally illuminated pedestrian crossing sign, only the pedestrian crossing sign and its vicinity are illuminated, so visibility is poor for pedestrians on the pedestrian crossing, which may cause accidents such as jumping out. It often becomes. Therefore, in many cases, a street lighting is provided separately from the pedestrian crossing sign. However, installing a street light in addition to the pedestrian crossing light not only requires double cost, but also causes the street light to directly illuminate the driver of the vehicle. There is a problem that there is a risk of dazzling the driver and hindering safe driving. Therefore, the applicant previously disclosed in Japanese Utility Model Publication No. 22784/1990 that one shield beam is built in the lower part of the main body of the pedestrian crossing sign light, and this shield beam can be used to identify pedestrian crossings and pedestrians.
Illuminate and let the driver of the vehicle confirm this,
It is proposed to prevent the driver of a vehicle stopped immediately before the pedestrian crossing from being dazzled and to minimize traffic accidents on the pedestrian crossing at night.

However, the previously proposed pedestrian crossing sign light has only one shield beam, so the light intensity may be insufficient depending on the installation location. To increase the light intensity, If a halogen lamp is adopted and an air-cooling fan is provided to prevent the temperature inside the marker lamp from rising due to the halogen lamp, there is a problem that the cooling effect is lowered due to a failure of the air-cooling fan and the safety cannot be ensured. Further, if a large shield beam is adopted, the entire sign lamp becomes large in size accordingly, and there is a problem that the sign lamp may not be installed due to the installation space and the like. The present invention was created in view of the above problems, and can ensure safety even if the air-cooling fan malfunctions, and also provide road lighting at the bottom of the main body of the pedestrian crossing sign light. By arranging a plurality of them and arranging the irradiation direction of the lighting for each road to be freely changeable, the irradiation direction of the lighting for each road is dispersed to irradiate a wider range, while A pedestrian crossing that can concentrate the irradiation direction of road lighting to illuminate a relatively narrow area with high illuminance, prevent enlargement, and respond flexibly according to the situation of the installation site.

And an inner cover 32 having a substantially rectangular tube shape, which is installed in the outer cover 31. The outer cover 31 shuts off the interior of the lamp unit 30 and the interior of the main body 11 so that they cannot communicate with each other, and the gap between the peripheral wall portion of the outer cover 31 and the peripheral wall portion of the inner cover 32 is the outside air intake passage 33. It has become. An intake port of the outside air intake passage 33 is opened in the bottom surface of the main body 11 in a circumferential shape.

A heat shield plate 52 is attached to the lower support base 51 so as to shield the rotating shaft portion of the air-cooling fan 50 from below. The heat shield plate 52 is for preventing the rotating shaft portion of the air-cooling fan 50 from breaking down due to radiant heat from the pedestrian illumination 20 side. At the lower end of the inner cover 32, the pedestrian illumination 20 is supported via a kind of universal joint 53. The universal joint 53 has a pair of angle adjusting shafts 54 and 55 so that the angle adjusting directions of the optical axes thereof are orthogonal to each other.

A halogen lamp having a high luminous intensity is used as the pedestrian illumination 20. The axial direction of the shaft 54 for angle adjustment faces the left-right direction of the main body 11, and the axial direction of the shaft 55 for angle adjustment faces the front and rear face direction of the main body 11, and as a result, in FIGS. As shown in the figure, the mounting posture of the pedestrian lighting 20 is inclined in the forward and rearward directions and the left and right directions of the main body 11, and the light for the pedestrian crossing is to be installed according to the width or length of the pedestrian crossing. The irradiation direction, which is the axial direction, can be adjusted.

Further, a hood 12 can be attached to the peripheral edge of the lower opening of the main body 11 if necessary. As shown in FIG. 2, the hood 12 hangs a light-shielding edge toward the front side downward longer than the other side, and in relation to the inclination direction of the lighting 20 for pedestrians, the hood side toward the lane of the pedestrian crossing. The hood 12 has an enhanced light-shielding effect.
Can be configured so that if the pedestrian lighting 20 is damaged for some reason, the fragments will fall onto the pedestrian crossing and will not cause damage to pedestrians, vehicles and vehicle drivers. . As shown in FIG. 7, the pedestrian crossing sign controller 19 accommodates a nighttime detection unit 61, which is a nighttime detection unit mainly composed of a photodiode, and is stored in the nighttime detection unit 61.
Is output to the AND circuit 62, and the AND circuit 6
The output signal 2 is output to the relay circuit, and the a contact rl1 of the relay circuit is connected to the pedestrian illumination 20. The crosswalk sign controller 19 accommodates a chattering removal timer circuit 63 and a lighting time control timer circuit 64, and the detection signal of the man sensor 40, which is a road environment detection unit, causes the chattering removal timer circuit 63 and the lighting time control timer circuit 64 to be detected. It is output to the AND circuit 62 via. Further, the switch in the push button box 65 is connected to the AND circuit 62 via the lighting time control timer circuit 64.

FIG. 8 shows a control circuit of the pedestrian illumination 20. That is, one output terminal of the 100V AC power supply is connected to the other output terminal via the a contact rl1, the one pedestrian illumination 20 and the variable resistor R1. Similarly, one output terminal of 100V AC power supply,
It is connected to the other output terminal via the a-contact rl1, the other pedestrian illumination 20 and the variable resistor R1.

The 100 V AC power source is connected to the DC motors M1 and M2 of the air-cooling fan 50 via the transformer T1 and the rectifier circuit D1. As shown in FIG. 9, the DC motors M1 and M2 are provided with a rotation detection circuit. The rotation detection circuit is composed of a transistor and a diode connected in parallel, a voltage of 30 V is applied to the collector, and the emitter is grounded. At a normal rotation speed, for example, 2500 rpm, the base voltage of the rotation detection circuit becomes equal to or higher than the threshold value, the collector output becomes low level, and the rotation speed is a predetermined number lower than the normal rotation speed of 1700 rpm.
Then, the base voltage of the rotation detection circuit becomes lower than the threshold value and the collector output becomes high level.

The collector output end of the rotation detection circuit is connected to the DC motors M1, M via the coils RL1, RL2 of the relay circuit.
2 is connected to each + terminal. DC motor M
Each + terminal of 1 and M2 is set between 15V and 30V. The diodes D2 and D3 for preventing back electromotive force are connected in parallel to the coils RL1 and RL2 of the relay circuit. The coils RL1 and RL2 of the relay circuit are the rectifier circuit D1 when the collector of the rotation detection circuit is at a low level.
Current flows from the + terminal of the a-contact rl1 and rl2, and when the collector of the rotation detection circuit is at a high level, no current flows from the + terminal of the rectifier circuit D1 and the a-contact rl1 and rl2. It was designed to open.

Next, the operation will be described. For example, at night, the night switch is activated to turn on the fluorescent lamp 18, and the pedestrian crossing sign displayed on the front part of the main body 11 of the pedestrian crossing sign lamp 10 is illuminated. The letters and patterns are clearly displayed.

Two pedestrian lights 20 for illuminating the road are arranged in parallel at the lower part of the main body 11 of the pedestrian crossing sign light 10, and the halogen lamp diameter of the halogen lamp is not made large. Since the luminous intensity can be increased, it is not necessary to widen the front and rear width of the marker light, and it is not necessary to increase the size.
Further, the pedestrian illumination 20 is provided with a pair of angle adjusting shafts 54, so that the angle adjusting directions of the optical axes thereof are orthogonal to each other.
Since they are rotatably supported via 55, the mounting posture of the pedestrian lighting 20 is tilted in the forward and rearward directions of the main body 11 and in the left and right directions, and the optical axis of the pedestrian crossing indicator light 10 is tilted. You can adjust the irradiation direction, which is the direction
It is possible to disperse the irradiation directions of the two pedestrian illuminations 20 to irradiate a wider range, while concentrating the irradiation directions of the two pedestrian illuminations 20 to increase the relatively narrow range. It is possible to illuminate with illuminance, and it is possible to flexibly respond to the situation of the installation location of the pedestrian crossing sign lamp 10. By providing the outside air intake passage 33, the inside of the main body 11 of the pedestrian crossing indicator light 10 is illuminated by pedestrians 2
The main body 11 of the pedestrian crossing light 10 can be configured to have a double structure separated from the 0 side, and the inside of the main body 11 of the pedestrian crossing light 10 cannot be ventilated from the outside. It is possible to prevent the inside of the container from being contaminated.

The outside air intake passage spatially separates the inside of the main body of the pedestrian crossing sign lamp 10 from the side of the pedestrian lighting 20 to eliminate air communication, and dust and the like in the outside air can be crossed. The inside of the main body of the indicator light 10 for use will not enter. The nighttime detection unit 61 detects that it is nighttime,
Further, when the man sensor 40 detects a pedestrian crossing, the detection signal of the nighttime detection unit 61 is directly fed to the AND circuit 62.
Is output to the AND circuit 62 via the chattering removal timer circuit 63 and the lighting time control timer circuit 64, and the output terminal of the AND circuit 62 becomes high level. Similarly, even if the switch in the push button box 65 is pressed, the output terminal of the AND circuit 62 becomes high level.

At normal times, for example, the air-cooling fan 50 has two
It is rotating at 500 rpm, the base voltage of the rotation detecting circuit becomes higher than the threshold value, and the collector output becomes low level. When the collector of the rotation detection circuit is at a low level, the coil of the relay circuit is energized, the current from the rectifier circuit D1 is flowing through the coils RL1 and RL2 of the relay circuit, respectively, and the a contacts rl1 and rl2 are closed. Therefore, when the output terminal of the AND circuit 62 becomes a high level, an AC 100V voltage is applied to the pedestrian illumination 20 through the a-contacts rl1 and rl2 of the relay circuit, respectively. The lighting 20 is turned on. Also, AND
When the output terminal of the circuit 62 becomes high level, the switching element 17 is closed and the DC 12V voltage blinks.
Is applied to the blinking light 15 via the
5 blinks.

Lighting for pedestrian 20 Lighting for lighting 15 Lighting for blinking 15 About 30 seconds after the blinking, the lighting time control timer circuit 64 operates to turn on the lighting time control timer circuit 64.
Is turned off, the output end of the AND circuit 62 becomes low level, the pedestrian illumination 20 is turned off, and the blinking illumination 15 does not blink. That is, at night,
And when a pedestrian crossing exists, the lighting 15 for blinking will blink automatically, and the lighting 20 for pedestrians will light up automatically,
Not only can the driver's attention be paid to the driver, but also the pedestrian can be sufficiently illuminated to ensure safety.

Normally, when the pedestrian lighting 20 is turned on,
The air-cooling fan 50 operates to prevent the temperature inside the main body of the pedestrian crossing sign lamp 10 from rising. When the pedestrian illumination 20 is on, for example, when the air-cooling fan 50 is in an abnormal operation state and its rotation speed drops below 1700 rpm, the base voltage of the rotation detection circuit becomes lower than the threshold value. And the collector output goes high. When the collector of the rotation detection circuit is at a high level, no current flows from the + terminal of the rectifier circuit D1, the coil of the relay circuit is de-energized, the a contacts rl1 and rl2 are opened, and the pedestrian illumination 20 is turned on. It will not turn on. Thereby, the lighting 20 for pedestrians can be turned on and the cooling effect of the air-cooling fan 50 can be avoided to be insufficient, and the temperature rise inside the main body of the signboard 10 for pedestrian crossings can be prevented. You can Further, since the heat shield plate 52 is arranged in the gap between the pedestrian illumination 20 and the fan rotation shaft portion of the air-cooling fan 50, the fan rotation shaft portion radiates heat from the pedestrian illumination 20 side. Therefore, it is not necessary to overheat, and the failure factor of the air cooling fan 50 can be eliminated.

[0031]

In the traffic light for pedestrian crossing according to the present invention, when the air-cooling fan is in an abnormal operation state due to a failure or the like, the road lighting is not turned on. Safety can be ensured, and multiple road lights are installed in parallel under the main body of the pedestrian crossing sign, and the irradiation direction of each road light can be freely changed. This makes it possible to distribute the irradiation direction of the lighting for each road to irradiate a wider range, or to concentrate the irradiation direction of the lighting for each road to illuminate a relatively narrow range with high illuminance. Therefore, it is possible to prevent an increase in size and flexibly respond to the situation of the installation site.
