Description

  The present invention is a roadside illumination device for retrofitting an arrow feather post that displays the position of the roadside when there is snow, and is particularly effective when nighttime weather conditions deteriorate, such as snowstorms. The present invention relates to a road shoulder lighting device.

  In the case of a conventional arrowhead for roadside indication, a solar battery and LED are attached to the arrowhead so that the driver can easily see the arrowhead, or when snowfalls, and the road shoulder is good due to snowfall. An idea devised to irradiate illumination light to ensure traffic safety when not known is introduced in Utility Model Registration Publication No. 3090966 (Patent Document 1).

However, although this device can be put into practical use for newly produced arrow feathers, it cannot be retrofitted to existing arrow feathers.
In addition, especially in winter and at night, weather conditions often deteriorate. For example, in the case of a snowstorm or heavy rain, the illumination light may not reach the road shoulder and may be useless.

  Japanese Patent Application Laid-Open No. 2005-07642 (Patent Document 2) discloses a device for monitoring the depth of snowfall during snowfall, a self-luminous arrow blade, a light emitter attached to the arrow blade, and a light emitter. An image processing apparatus has been introduced that receives light reflected from a snow cover surface when irradiated and calculates the depth of the snow cover.

  However, even in this example, even if it can be used for new installation, there is a problem that it cannot be retrofitted to an existing arrow blade, and there is no means for dealing with the deterioration of the weather conditions described above.

Explanation of control circuit Illustration of LED emission flowchart

  FIG. 1 is an explanatory view showing the configuration of the present invention, wherein reference numeral 1 is an arrow feather sign having an arrow blade 2 attached to the tip of a pillar 3, 4 is a road surface, 5 is a road shoulder, and 6 is snow. Show.

  Reference numeral 7 denotes an illumination box attached to the tip of the support column 3 using a U-band 9 on the back side of the arrow blade 2, as shown in FIG. The LED 8 is built in downward (vertical direction), and the LED 8 illuminates the road shoulder 5.

  Reference numeral 10 denotes a power generation control means control box attached to the column 3 by a U-band 10a. The control box 10 stores a solar panel 12 serving as a power source for the LED 8 and an electromotive force of the solar panel 12. The storage battery 21 and the control circuit 11 (FIG. 5) are assembled.

As shown in FIG. 5, the control circuit 11 includes a solar panel 12, a storage battery 21, a day / night detection sensor 13, an air temperature detection sensor 14, a humidity detection sensor 15, a wind speed detection sensor 16, and a rain detection sensor 17 using ultrasonic waves. The day / night detection sensor 13 supplies power from the storage battery 21 to the LED 8 only at night to emit light, and in response to this light emission, the light emission of the LED 8 and its light in response to signals from the various sensors 13 to 17 Select the emission color and make it flash.
In this embodiment, the blinking speed and light emission intensity (irradiation brightness) are controlled so as to change according to weather conditions.

  Reference numeral 18 in the figure is a signal cable connecting the lighting box 7 and the control box 10.

Next, the operation of the embodiment described above will be described in detail corresponding to each weather change example.
(1) Normal time When the day / night detection sensor 13 detects a certain darkness, the control circuit 11 controls the power supply of the LED 8 to be ON, and when it detects a certain brightness, it controls it to be OFF.
In general, a commercially available sensor can be used as the day / night detection sensor 13. Further, since the day / night detection sensor 13 sometimes becomes constant dark during the day, the LED 8 is driven even in such a case.
The use of the emission color of the LED 8 is arbitrary, but it is a matter of course that the color having the most illumination effect is selected according to the weather conditions.

(2) During snowfall The control circuit 11 determines that there is snow and there is snow when the day / night detection sensor 13 is turned ON and the temperature detection sensor 14 and the rainfall detection sensor 17 detect certain values. And drive the LED.
At this time, the LED 8 emitting yellow light, which is not normal white light emission, may be driven to improve visibility.

(3) During a snowstorm,
The control circuit 11 has a snowstorm when the wind speed sensor 16 detects a wind speed above a certain value in accordance with the signals from the day / night detection sensor 13, the temperature detection sensor 14, and the rainfall detection sensor 17 of (2). It judges that it is a thing, and drives LED8 of yellow light emission. However, since there is snowstorm even during the day, even if the day and night detection sensor 13 is not driven, if the temperature detection sensor 15, the rain detection sensor 17 and the wind speed sensor 16 are driven, it is determined that there is a snowstorm and the LED 8 is turned on. To drive.

(4) During heavy rain,
The control circuit 11 determines that there is heavy rain when the rainfall detection sensor 17 detects a rainfall of a certain value or more, and drives the yellow light emitting LED 8 even when no signal is input from the day / night detection sensor 13.

(5) During heavy fog,
Regardless of the presence or absence of a signal from the day / night detection sensor 13, the control circuit 11 drives the yellow light emitting LED 8 when a signal of a certain value or more is input from the humidity detection sensor 15.

(6) If there is no car or traffic,
The control circuit 11 is provided with a well-known automobile or human body detection sensor (not shown) and controls the power of the LED 8 to be turned off when no signal is input from the automobile or human body detection sensor in order to prevent power consumption. If there is, the power supply is controlled to be ON, and the above operations (1) to (5) are prepared.

(7) synchronous drive,
Since the arrow blades 2 are installed along the road shoulder 5 at regular intervals, each lighting device is individually driven. However, since this makes noise, it is driven synchronously in the same area. For this reason, GPS and JJY20 are used.

(8) Voice drive,
The control circuit 11 outputs a sound for calling attention from a speaker or the like in conjunction with driving of the lighting device. This voice is particularly effective for motorcycles, bicycles and pedestrians.
Note that the light emission of the LED 8 is basically a flashing light emission, but a light emission that does not flash can be adopted depending on conditions.

  FIG. 6 shows a driving flow of the lighting device. When the control circuit is turned on and starts (S1), the day / night detection sensor 13 determines day and night (S2), and the temperature sensor 14 and the rainfall sensor 17 or humidity. The detection sensor 15 determines freezing (S3). If YES, the red LED 8 is caused to emit light (S5). If NO, it is determined whether the visibility is poor (S6). If YES, The yellow LED 8 is caused to emit light (S7). If NO, the green LED 8 is caused to emit light (S8), and when the day / night detection sensor 13 detects a certain brightness, the light emission of the LED 8 is turned off to prepare for re-drive (S9).

Further, even when the day / night detection sensor 13 does not detect nighttime, when the dense fog is detected, it is determined that the visibility is poor, the yellow LED 8 is caused to emit light (S10), and the dense fog is not detected. Alternatively, when no dense fog is detected on the way, the LED 8 is turned off to prepare for re-drive (S12).
In addition to the combination with the arrow blade 2 described above, the lighting device according to the present invention may be used in addition to a snow pole, a snow fence, an illumination lamp, or an emergency evacuation guide light, etc. It can also be used.
Moreover, you may make it use for this this illuminating device combining various surveillance cameras.
