Description

  The present invention relates to a warning light.

  When carrying out maintenance and repair work of the road surface on the expressway, traffic restrictions are required to secure a working space. In addition, when traffic regulation is implemented, in order to ensure the safety of the operator and the occupants of the traveling vehicle, the traffic regulation is notified to the driver who is traveling toward the traffic regulation area, especially from the upstream side. To change lanes etc.

  For such a demand, for example, in Patent Document 1, there is known a light emitting display plate which includes a battery and urges a lane change to a distant traveling vehicle by emitting an LED as a light source.

JP 2012-132248 A

  Usually, when traffic control is implemented, a load cone or the like for guiding a traveling vehicle, for example, over several tens of meters, is disposed upstream of the work space, and light emission as described above is further upstream of these low cones. A display board and a warning light for notifying a driver who is traveling toward the traffic regulation area from the upstream side are notified of the traffic regulation.

  Here, when using a warning light that has a light emitting element for emitting warning light and includes a battery that supplies power to the light emitting element, the remaining capacity of the battery decreases and the light emitting element decreases during traffic control. It is necessary to turn off and ensure that the warning function of the warning light is lost.

  However, with the conventional warning light, it is not possible to check the remaining battery capacity of the warning light located at the top of the traffic regulation area while the worker is in the work space. Therefore, when the battery remaining capacity decreases during traffic control and the luminance of the light emitting element decreases or disappears, the operator can not immediately notice it, and the warning function of the warning light is reduced or lost. There is a risk of continuing.

  Moreover, in order to obtain the light emission state of the warning light during traffic control in the first place, it is necessary for the operator to move to the first position of the traffic restriction area and directly check the light emission state of the warning light. However, moving the worker to the first position in the traffic control area is dangerous and causes a problem in terms of safety.

  This invention is made in view of such a problem, and an object of the present invention is to provide art which an operator can grasp easily while remaining in a work space of a battery of a warning light.

  According to an embodiment of the present invention, a warning light for notifying a driver of a traveling vehicle of a traffic restriction, displaying a battery, a first light emitting element for notifying the traffic restriction, and a remaining capacity of the battery And a second light emitting element, and an irradiation direction of the second light emitting element is a back direction of an irradiation direction of the first light emitting element.

  According to the above aspect, since the display of the remaining battery capacity is irradiated in the back direction of the irradiation direction of the warning light, the remaining capacity of the battery of the warning light can be easily grasped while the worker is in the work space.

It is a front view of a warning lamp of a 1st embodiment of the present invention. It is a side view of a warning lamp of a 1st embodiment of the present invention. It is a rear view of the warning lamp of a 1st embodiment of the present invention. The example which applied the warning lamp of 1st Embodiment of this invention to traffic regulation is shown. It is a front view of a warning lamp of a 2nd embodiment of the present invention.

  Hereinafter, a warning lamp 1 according to an embodiment of the present invention will be described with reference to the drawings.

First Embodiment
FIG.1, FIG.2, and FIG.3 are schematic block diagrams which show the structure of the warning lamp 1 of 1st Embodiment. FIG. 1 shows a front view of the warning lamp 1 of the present embodiment, FIG. 2 shows a side view of the warning lamp 1, and FIG. 3 shows a rear view of the warning lamp 1.

  First, the configuration of the warning lamp 1 will be described with reference to FIGS. The warning lamp 1 is configured to include a light emitting unit 100 and a power supply unit 200.

  The light emitting unit 100 includes a light emitting unit 110 having a plurality of high brightness LEDs on the front side (front side). Here, the “front side” is a side that coincides with the irradiation direction of the warning light for notifying the traveling vehicle of traffic regulation. That is, the irradiation direction of the light emitting unit 110 is the front direction of the warning lamp 1. In addition, the “irradiation direction” here is a direction in which the luminous intensity is the largest when viewed from the light source when the light emitting unit 100 emits light.

  The light emitting unit 110 emits warning light for notifying of traffic regulation. The light emitting unit 110 according to the present embodiment is configured by arranging the red LED element 110r, the orange LED element 110y, and the blue LED element 110b at predetermined intervals. Therefore, the warning lamp 1 of the present embodiment can emit warning lights of at least three or more colors.

  The LED elements (110r, 110y, 110b) of the respective colors disposed in the light emitting unit 110 use high-brightness LED elements which can be easily viewed even in a distant traveling vehicle. The luminous intensity of each LED element in the present embodiment is set to a value capable of realizing (irradiating) an amount of light equal to or greater than the amount of light of the general warning lamp placed on the road.

  Further, in the example shown in FIG. 1, a total of 36 light emitting elements (high luminance LEDs) of six in the horizontal direction and six columns in the vertical direction are provided. More specifically, from the top, two rows in the vertical direction, a total of 12 red LED elements 110r, below that, two rows in the vertical direction, a total of 12 orange LED elements 110y, further below that, in the vertical direction A total of 12 blue LED elements 110b are arranged in two rows.

  With such an arrangement, in the light emitting portion 110, a red region R in which twelve red LED elements 110r are arranged, an orange region Y in which twelve orange LED elements 110y are arranged, and twelve blue LED elements Three regions, blue region B in which 110b are arranged, are configured. The red area R, the orange area Y, and the blue area B form a planar light emitting area by a plurality of LEDs of the same color, so the luminance can be increased as the whole light emitting area, and visibility from a distance can be enhanced. it can. However, the number balance of these arrangement and each color LED element is an example, and is not limited to what is illustrated. For example, the LED elements of each color may be arranged by being divided horizontally for each row, or may be arranged irregularly.

  The handle portion 12 is a substantially U-shaped grip portion provided on the warning lamp 1 so that a part thereof protrudes upward.

  The bracket 13 is a substantially U-shaped attachment (attachment portion) provided on the warning lamp 1 so that a part thereof protrudes downward. In the bracket 13 of this embodiment, screw holes are processed, and two pedestals 14 are attached by bolting. Thereby, the warning light 1 can be placed on the road surface via the pedestal portion 14.

  The bracket 13 and the pedestal portion 14 may be configured to be attachable to a guard rail, a regulation sign, a regulation car used for traffic regulation, heavy machinery and the like by changing the shapes and the like. For example, the warning lamp 1 can be configured to be attachable to a metal part of a heavy machine by providing a magnet at the bottom of the pedestal portion 14.

  The power supply unit 200 includes a battery 201 for supplying power to the light emitting unit 110, a power switch 210 (see FIG. 3), an operation switch 220, and a charging connector 230. Then, on the back of the power supply unit 200, a battery remaining capacity display unit 240 which is a feature of the present invention is provided (see FIG. 3).

  The battery 201 is desirably small and light in weight and large in capacity in consideration of portability. For example, a lithium iron phosphate battery is used. The capacity of the battery 201 may be, for example, a sustainable capacity for about 10 hours in a state where all of at least one color area (for example, the red area R) of the light emitting unit 110 is lit.

  The power switch 210 is a switch that switches ON / OFF of the warning light 1. When the power switch 210 is switched to the on state, the power switch 210 supplies the power of the battery 201 to the LED element of the light emitting unit 110.

  The operation switch 220 is a switch for changing the light emission pattern of the LED element in the light emitting unit 110. The light emission pattern of this embodiment is, for example, as follows. First, when the power switch 210 is switched to ON, only the red region R is lit (initial state). Here, when the operation switch 220 is pressed, the red region R is turned off and only the orange region Y is turned on. When the operation switch 220 is further pressed, the orange area Y is turned off and only the blue area B is turned on. Then, when the operation switch 220 is pressed, the blue area B is extinguished, and only the red area R blinks. As described above, the warning light 1 is configured such that when the operation switch 220 is pressed, the light emission patterns set in advance are sequentially switched.

  The charge connector 230 is a connector to which a power cable or the like for charging the battery 201 from an external power source is attached. That is, the warning light 1 is configured to be able to charge the provided battery 201 by the external power supply.

  Next, with reference to FIG. 3, the remaining battery charge display unit 240 will be described.

  The remaining battery charge indicator 240 is attached to the back of the warning light 1 as shown. The battery remaining capacity display unit 240 includes a red LED element 240r, an orange LED element 240y, and a blue LED element 240b, and emits light (remaining capacity display light) capable of recognizing the remaining capacity of the battery 201. The irradiation direction of the remaining capacity display light emitted by the LED elements of each color constituting the battery remaining capacity display unit 240 is the back direction of the warning lamp 1 as illustrated.

  That is, the irradiation direction of the LED elements (240r, 240y, 240b) of each color constituting the battery remaining capacity display unit 240 is the back direction of the irradiation direction of the LED elements (110r, 110y, 110b) constituting the light emitting unit 100. . In other words, the battery remaining capacity display unit 240 emits the LED light for displaying the battery remaining amount in the direction opposite to the direction in which the light emitting unit 110 emits the warning light.

  Further, as the red LED element 240r, the orange LED element 240y and the blue LED element 240b constituting the battery remaining capacity display portion 240, light emitting elements capable of realizing a luminous intensity visible even from a distance are employed. In other words, the light intensity of each of the LED elements (240r, 240y, 240b) in the present embodiment may be sensitive to human eyes in the distance. For example, the battery remaining capacity display unit 240 of the present embodiment is configured to be distinguishable from a position at which the remaining capacity display light is separated by 50 m or more. In other words, at least one of the LED elements of each color constituting the battery remaining capacity display unit 240 is configured to be able to check the lighting / non-lighting from a position at a distance of 50 m or more.

  Then, the battery remaining capacity display unit 240 acquires the charge capacity of the battery 201, and displays the remaining capacity by the LED elements 240r, 240y, 240b based on the acquired size of the charge capacity (that is, the remaining capacity of the battery 201). Control the lighting pattern of light.

  For example, the remaining battery charge display unit 240 lights up as follows according to the remaining charge capacity of the battery 201. That is, the battery remaining capacity display unit 240 lights only the blue LED element 240b until the charge amount of the battery 201 reaches half capacity (50%) from full charge (100%), and the remaining capacity is 49% to 20%. Up to%, the orange LED element 240y is turned on, and for the remaining capacity of 19% to 10%, the red LED element 240r is turned on. Then, when the remaining capacity becomes 9% or less, the red LED element 240r is blinked.

  In addition, said lighting pattern is an example and is not restricted to this. For example, nothing is turned on until the remaining capacity falls below 50%, the remaining capacity falls to 49% or less and the red LED element 240 is turned on, and when the remaining capacity falls below 20%, the red LED element 240 blinks You may configure it. That is, the number of colors of the LED elements constituting the battery remaining capacity display portion 240 and the light emission pattern thereof are not particularly limited, and at least the remaining capacity is reduced before the remaining capacity reaches 0% (requiring charge Is configured to be recognizable.

  Next, referring to FIG. 4, an example in which the warning light 1 of the first embodiment of the present invention is applied to traffic control on a motorway 1000 will be shown.

  FIG. 4 shows a state in which traffic restriction for securing the work space is performed when performing repair work on a road. Specifically, an automobile road 1000 shown in FIG. 4 has lanes 1100 and 1200 traveling in the same direction, and in the lane 1100 in contact with the roadside zone 1300, a work area for repairing the road surface. Traffic regulations have been implemented to secure 2000. In the lanes 1100 and 1200, the traveling direction of the vehicle is defined in the direction from the lower side to the upper side in FIG. Further, at the most upstream side of the work area 2000, a regulated car 300 provided with a sign for notifying the repair work site is stopped. In addition, the control vehicle 300 is an example, Comprising: It will not specifically limit, if it is a general vehicle arrange | positioned at a construction site, such as a sign car, a construction machine (heavy machine), for example.

  A plurality of road cones 400 arranged at equal intervals are arranged around the work area 2000 (see hatching area), and on the upstream side, three arrow signs for prompting the traveling vehicle to change lanes are provided. It is arranged.

  Then, the warning lamp 1 is placed further upstream of the arrow mark. The light emitting unit 110 of the warning lamp 1 emits warning light in the front direction (irradiation direction 1a) to notify traffic regulation to a vehicle traveling from the upstream toward the repair work site. On the other hand, the battery remaining capacity display unit 240 of the warning lamp 1 emits remaining capacity display light capable of recognizing the remaining capacity of the battery 201 in the back direction (irradiation direction 1b).

  The remaining capacity display light emitted toward the irradiation direction 1b can be identified from a distance of 50 m or more as described above. Therefore, while the worker in the work area 2000 is in the work area 2000 where safety can be ensured, the light emission of the light emitting unit 110 according to the remaining charge amount of the warning light 1 placed far away, that is, the remaining charge amount You can check the status.

  The warning light 1 of the first embodiment described above is a warning light for notifying the driver of the traveling vehicle of the traffic restriction, and the battery and the first light emitting element for notifying the traffic restriction (LED elements 110r, 110y 110b) and a second light emitting element (LED elements 240r, 240y, 240b) for displaying the remaining capacity of the battery, and the irradiation direction of the second light emitting element is the back direction of the irradiation direction of the first light emitting element. It is. Thus, the light emission (warning light) of the first light emitting element of the light emitting unit 110 informs the traveling vehicle of the existence of traffic restriction, and the display of the remaining battery charge is irradiated in the back direction of the warning light irradiation direction. Thus, the remaining capacity of the battery 201 of the warning light 1 can be easily grasped while the operator is in the work space. As a result, the remaining capacity of the battery 201 becomes zero during traffic control, and it is possible to prevent the warning light from being turned off unexpectedly.

  In addition, the operator does not have to move to the installation position of the warning light 1 (the most upstream position of the traffic restriction area) to confirm the battery charge amount of the warning light 1 during traffic restriction, so Safety can be improved.

  Further, according to the warning lamp 1 of the first embodiment, a vehicle for displaying the area to the driver is disposed in the area where traffic regulation is performed, and the warning lamp 1 is disposed on the road upstream of the vehicle. In this case, the luminous intensity of the second light emitting element (LED elements 240r, 240y, 240b) is set to a luminous intensity that can be recognized by an operator who is downstream of the vehicle. Moreover, a vehicle here is a regulation vehicle, a sign car, or a construction machine. As a result, the remaining battery capacity of the warning light 1 can be easily identified even by a worker present at a position distant from the installation place of the warning light 1 (e.g., a position separated by 50 m or more).

Second Embodiment
Next, a warning lamp 1 according to a second embodiment of the present invention will be described with reference to the drawings.

  FIG. 5 shows a front view of the warning lamp 1 of the second embodiment of the present invention. The same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The warning lamp 1 of the second embodiment is provided with a recorder 500 on the top of the light emitting unit 100 toward the front side of the light emitting unit.

  The recorder 500 includes the camera 500a, and also includes therein a controller including a CPU, a memory, and the like, and a non-volatile memory such as an SD card. The controller always records the video data acquired by the camera 500a in the memory. Not only video but also audio may be stored simultaneously. Furthermore, a sensor for detecting an impact may be provided, and when an impact is detected, video data before and after the time when the impact is detected may be extracted and recorded in the non-volatile memory.

  The specifications of the recorder 500 may be the same as those of a conventionally known drive recorder. However, since the recorder 500 of the present embodiment is provided to the warning light 1 and is usually used outdoors, it is preferable that the recorder 500 have high waterproofness and dust resistance to the internal circuit.

  With such a configuration, in the warning lamp 1 arranged as shown in FIG. 4, even if the traveling vehicle erroneously attempts to rush into the work area 2000, it can be recorded in the non-volatile memory as video data. Since it can be done, it can be used as an analysis of the cause of the accident and as research data for accident prevention measures.

  As mentioned above, although embodiment of this invention was described, the said embodiment is only what showed one of the application examples of this invention, and the meaning which limits the technical scope of this invention to the specific structure of the said embodiment is not.

  For example, although the battery according to the embodiment of the present invention has been described by way of example of the lithium iron phosphate battery, it is not limited thereto, and may be a small, lightweight and high capacity battery. For example, a lithium ion polymer battery or a nickel hydrogen battery may be used.

  Further, the light intensity of each LED element, the duration of the battery (10 hours), and the distance capable of identifying the remaining capacity display light described in the present specification are exemplifications and not limited thereto. For example, 50 m mentioned above as the distance that can identify the remaining capacity display light is the distance that is required depending on the road conditions where the construction site such as repair work is done and the traffic regulation mode (length in the vehicle travel direction of traffic regulation area) And may be, for example, 30 m. Note that these prescribed values are not exact values, and include values slightly higher or lower. Further, these prescribed values may be appropriately adjusted in consideration of the total charge amount of the battery 201 mounted on the warning lamp 1, the weight of the battery 201, the current consumption amount of each LED light emitting element, and the like.

  Further, the light emitting element as the light source described above does not necessarily have to be an LED, and may be, for example, a flash.
