Description

  The present invention relates to a self-light-emitting sign corresponding to a power failure, which is installed at an intersection and lights up and displays a point name sign plate which displays the name of the point of the intersection so that it can cope with a power failure.

  The name of the point or the name of the point indicating the name of the point of intersection is usually attached to the intersection, and a point name sign board in which the name of the point is written on the reflection sheet is placed at an easy-to-see position for the driver above the intersection. However, since the conventional point name signboard is installed in a state where it does not emit light or is not illuminated, it is a signboard that is difficult for an automobile driver to see at night and at intersections without illumination. Moreover, since the point name sign board is usually installed above the intersection, it is difficult for the driver to see the light from the headlight of the car at night and to be seen by the driver.

  On the other hand, as a temporary stop sign board installed at an intersection, a light-emitting sign board that has been conventionally provided with a light emitter and that emits light at night is proposed in Patent Document 1 below.

JP-A-9-59943

  However, at normal intersections without a stop sign at night, there are no temporary stop signs such as reflective or internal lighting. The place name sign board is only installed in a state where it does not emit light.

  For this reason, even if a driver or a passerby of a car traveling at an intersection at night is installed with a point name sign board to provide a destination mark or guidance, the driver's attention and awareness are low. Tends to be careless ahead of the road. In addition, at night and at intersections where there are no traffic lights or road lights such as reflective or internal lighting, it is difficult for drivers or passers-by to recognize that they are intersections, which can lead to traffic accidents at night intersections. There was a problem.

  Also, even if there is a lighting facility that illuminates the intersection, this type of lighting facility illuminates the road surface at the center of the intersection, making it difficult to distinguish from street lights, and automobile drivers often do not notice the intersection.

  Furthermore, even if there is an intersection where a traffic light is installed, if there is a power outage in the event of a disaster or planned power outage, the traffic light will disappear. Even at an intersection, there was a problem that it was difficult to recognize the intersection at the time of a power failure, and it was easy to lead to a night traffic accident.

  The present invention has been made in view of the above-mentioned problems, and even during a power failure, the intersection point name sign board is lit and displayed at night so that the driver can recognize the existence of the intersection itself and prevent traffic accidents. The purpose is to provide a self-luminous sign that can be used in case of a power failure.

And a controller 6 as control means for controlling the LED 14 to light up.

  As shown in FIGS. 2 to 5, the point name sign plate 1 is configured to have a main body case 10 formed in a rectangular parallelepiped box shape, and a display surface is formed as a front opening 11 on the front surface of the main body case 10. And the translucent display board 12 which attached | subjected the point name to the front opening part 11 is attached facing the front via the packing 12a. As shown in FIGS. 4 and 5, the main body case 10 is formed in a box shape having a relatively thin front and rear width (for example, a thickness of 45 to 65 mm), and the front case 10a is connected to the front portion of the rear case 10b, and the hinge 10c. A fastening bracket 10d is attached to the opposite side of the hinge 10c so that the inside of the main body case 10 can be opened and closed during maintenance and inspection.

  The translucent display board 12 is formed of, for example, a translucent milky white synthetic resin board. As shown in FIGS. 5 and 6, the translucent display board 12 is made of a light-transmitting film such as blue with a character shape. A character sheet 17 having a point name formed by cutting is attached. The translucent display panel 12 is configured to illuminate and display the characters of the spot names by irradiating the backlight from behind the translucent display board 12 by a backlight device 13 disposed behind.

  In addition, the character sheet 17 stuck to the translucent display board 12 can also be formed using a translucent reflective sheet, for example, a point name is set to the rectangular white translucent reflective sheet used as a base sheet. The character reflecting sheet obtained by cutting out the characters and cutting out the character of the spot name from the chromatic light-transmitting reflecting sheet can be adhered to the cut-out portion of the white base sheet.

  The main body case 10 including the front case 10a and the rear case 10b is formed in a thin box shape by, for example, an aluminum plate, and a plurality of ribs 19 are welded in parallel in the vertical direction at intervals on the back surface of the rear case 10b. Is done. The plurality of ribs 19 are fixed for reinforcement and attachment, and are attached to the support column 20 using the ribs 19. When the body case 10 of the point name sign plate 1 is attached to the beam 21 of the support column 20 as shown in FIG. 1, it is fixed to the beam 21 of the support column 20 using a dedicated fixing bracket and rib 19. Yes.

  In the main body case 10, as shown in FIGS. 5 and 6, a backlight device 13 having a plurality of LEDs 14 and a light guide plate 15 is arranged in order to irradiate a backlight from behind the translucent display panel 12. Established. The backlight device 13 includes a light guide plate 15 made of a transparent synthetic resin plate on the front surface of the reflection plate 16, and a large number of light guide plates 15 are arranged only at the upper end of the light guide plate 15, or at the upper and lower ends, or along both end portions. The LED 14 is arranged facing inward. As shown in FIG. 6, a large number of fine V-grooves are formed on the back surface of the light guide plate 15, and light incident in the light guide plate 15 is guided by the fine V-grooves and the reflecting action of the reflection plate 16. The light is efficiently reflected in front of the light plate 15 and emitted. Further, as shown in FIG. 6, a diffusion sheet 15a is disposed on the front surface of the light guide plate 15, and the light guide plate 15 reflects the light incident from the edge thereof forward and diffuses the diffused light diffused through the diffusion sheet 15a on the front surface. The surface is emitted to the front side of the light guide plate 15.

  As shown in FIGS. 5 and 6, the periphery of the light guide plate 15 is held by a rectangular frame 18, and a substrate is disposed inside the frame 18, and a large number of LEDs 14 are arranged on the edge of the light guide plate 15. It is mounted at appropriate intervals with the part side facing. Thereby, the light irradiated from LED14 is entered into the light guide plate 15 from each side edge of the light guide plate 15, and the light reflected by the back surface of the light guide plate 15 and the front surface of the reflection plate 16 is diffused. The surface is emitted to the front side of the light guide plate 15 through 15a, and the entire surface of the translucent display plate 12 is irradiated with the backlight.

  The LED 14 has strong directivity and it is difficult to uniformly radiate the irradiation light to the surface, but the LED 14 is made to enter the irradiation light along the plane from each side edge of the light guide plate 15, and the back surface of the light guide plate 15 and the reflection plate The structure in which the light reflected by the front surface of 16 is emitted to the front side of the light guide plate 15 through the diffusion sheet 15a, thereby enabling uniform surface illumination while reducing the structure of the casing of the backlight device 13. Yes.

  In such a backlight device 13, for example, when the size of the light guide plate 15 is about 500 mm × 1200 mm, about 80 LEDs 14 are arranged in parallel facing the upper end of the light guide plate 15 at a pitch of about 15 mm. Can do. In this case, the power consumption of the LED 14 of the backlight device 13 is about 5 W, but the average plate surface illuminance of the light-transmitting display panel 12 is about 170 lx. The illuminance is high enough to be visible.

  As shown in FIG. 7, the control means for driving the LED 14 of the backlight device 13 is configured with a controller 6 that controls charging / discharging of the power storage unit 9 as a main part, and stores power generated by the solar cell 8. A body 9 and a day / night detector 7 for detecting daytime / nighttime and outputting a daytime signal or a nighttime signal are provided. The controller 6 is composed of a charge / discharge control circuit, an LED drive circuit, and the like. When a night signal is output from the night / day / night detector 7, the controller 6 supplies the power stored in the power storage unit 9 to the backlight device 13, When the daytime signal is output from the day / night detector 7 during daytime, the LED 14 is turned off and the electromotive force generated in the solar cell 8 is stored in the power storage unit 9 through the charge / discharge control circuit. It is like that. The day / night detector 7 detects the terminal voltage of the solar cell 8 and detects the night signal when the voltage is equal to or lower than the predetermined voltage. When the terminal voltage of the solar cell 8 exceeds the predetermined voltage, the day / night signal is detected. It can be configured to be detected.

  As shown in FIG. 1, the solar cell 8 is attached to the upper part of the column 20 of the traffic light 22, and the controller 6 and the power storage unit 9 are arranged in a control box 23 attached to the lower part of the column 20. The power storage unit 9 can be a secondary battery (capacity: about 12 V, about 44 Ah) such as a lithium ion secondary battery, a lithium ion polymer secondary battery, or a lead battery. Further, when a solar cell panel having a size of, for example, about 530 mm × 450 mm is used as the solar cell 8, electric power of about 16.4 V and 1.57 A can be generated. When the battery is charged, the point name sign board 1 can be turned on at night without charging during the day for about 7 days.

  In addition, as shown in FIG. 7, when not using the solar cell 8, it can replace with the solar cell 8 and can also comprise so that the electric power from the commercial power source S may be introduce | transduced into the controller 6, In this case, the commercial power source S The alternating current is converted to a direct current having a voltage of 12V and supplied to the controller 6. The controller 6 charges the power storage unit 9 using the power of the commercial power source S and lights the LED 14 at night using the power of the commercial power source S. Will be driven.

  For this reason, if a power failure occurs due to a disaster or the like when the commercial power source S is used, the power of the power storage unit 9 is discharged to drive the LED 14, but the power consumption of the LED 14 is small, For about 7 days, the LED 14 of the backlight device 13 can be turned on at night.

  As shown in FIG. 1, the self-light-emitting sign corresponding to a power failure having the above-described configuration is attached to the column 20 of the traffic light 22 installed in the vicinity of the intersection. As described above, the self-luminous sign corresponding to a power failure is attached to the part of the beam 21 attached to the upper part of the support column 20 of the traffic light 22 by using a dedicated fixing bracket. Note that, at an intersection without a traffic light, a dedicated support column is installed in the vicinity of the intersection, and the main case 10 of the self-luminous sign corresponding to a power failure is attached to the beam of the support column.

  Moreover, the solar cell 8 is attached to the upper part of the support | pillar 20, and the control box 23 incorporating the controller 6 and the electrical storage body 9 is attached to the lower part of the support | pillar 20. When the commercial power source S is not used, basically it is not necessary to connect to the commercial power source, so it is very easy to use at existing intersections and without affecting the lighting circuit of traffic lights. A self-luminous sign can be placed.

  When the daytime signal is output from the day / night detector 7 during the daytime, the controller 6 turns off the LED 14 and stores the electromotive force generated in the solar cell 8 in the power storage unit 9 through the charge / discharge control circuit.

  On the other hand, when the night signal is output from the day / night detector 7 at night, the controller 6 switches the power storage unit 9 from charging to discharging, and converts the power discharged from the power storage unit 9 to the LED 14 of the backlight device 13. To turn on the LED 14.

  Thereby, the light emitted from the LED 14 enters the light guide plate 15, the planar light is emitted through the diffusion sheet 15 a in front of the light guide plate 15 from the reflection plate 16, and translucent through the light guide plate 15 from the backlight device 13. A backlight is irradiated behind the display board 12, whereby the spot name sign board 1 is lit brightly.

  For this reason, the driver | operator of a motor vehicle can visually recognize the point name of an intersection easily at night, and can recognize the point. Furthermore, a driver of an automobile that passes through an intersection without a traffic light at night tends to overlook a spot name sign board in a dark state, but the translucent display board 12 of the spot name sign board 1 is provided by a backlight device 13. Since the display is lit, even if the intersection has no traffic light, it is possible to easily recognize the spot name and recognize the spot.

  In addition, the intersections without traffic lights at night are brightened by the lighting display of the point name sign board 1, so that the existence of the intersections can be easily recognized by the driver of the car, which makes it possible to prevent traffic accidents at night intersections. Occurrence can be prevented.

  On the other hand, when the commercial power supply fails during disasters or planned power outages, the traffic lights disappear at night at intersections with traffic lights. However, the controller 6 of the self-luminous sign corresponding to a power failure installed at the traffic signal at the intersection supplies the electric power discharged from the power storage unit 9 to the LED 14 of the backlight device 13 and drives the LED 14 to turn on. The sign board 1 is lit and displayed by the backlight device 13, and even if the commercial power supply is interrupted due to a disaster or planned power outage, the spot name sign board 1 is illuminated brightly to ensure the existence of an intersection. Can be recognized. In addition, when a disaster victim walks back on a dark road during a nighttime disaster, he / she can know where he / she is walking if he / she can see where he / she is walking if he / she sees the point name signboard lit at the intersection. be able to.

  In the above embodiment, the point name sign board 1 is installed on the column 20 at the intersection where the traffic signal 22 is present. However, the point name sign board 1 can be installed at the intersection where there is no traffic signal. In this case, the point name sign board 1 is attached using another sign post installed near the intersection or a dedicated post.

  Furthermore, in the self-light-emitting sign corresponding to a power failure according to the above embodiment, a human sensor for detecting a pedestrian is disposed at the intersection where it is installed, and when the pedestrian approaches the vicinity of the intersection, It is also possible to configure such that the detection signal is input to the controller, and the point name sign board 1 is displayed in a blinking manner or is turned on by changing the emission color. In addition, an automobile detection sensor that detects an automobile approaching the intersection is installed near the intersection. When the automobile approaches the intersection, a detection signal from the automobile detection sensor is input to the controller, and the point name sign board 1 is displayed blinking. Alternatively, it may be configured to display the lighting by changing the emission color.
