[Embodiment of the invention]

 FIG. 1 is an explanatory view of the overall configuration of the marker light according to the present invention, FIG. 2 is a top view, FIG. 3 is a front view, and FIG. 4 is a side view. The marker lamp 100 includes a dome-shaped light emitting unit 10 and a disk-shaped mounting unit 50. The light-emitting unit 10 includes a small solar panel 11 that performs solar power generation, a power storage unit 13 for storing power, for example, a lithium battery, a plurality of light-emitting bodies 15, and a control unit 17 that controls lighting and blinking of the light-emitting bodies 15. Has become.

The luminous body 15 is a red luminous body composed of a high-brightness LED (light-emitting diode) having a visible range of about 30 degrees. In this embodiment, four luminous bodies 15a, 15b, 15c, and 15d are used. It is juxtaposed. Each luminous body 15 is juxtaposed with an adjacent luminous body at an arrangement angle of 30 degrees when the center point of the marker lamp 100 is O. That is, the first light-emitting member 15a and the second light-emitting member 15b, the second light-emitting member 15b and the third light-emitting member 15c, and the third light-emitting member 15c and the fourth light-emitting member 15d. The radiators 15 are arranged radially so that the optical axis of each luminous body 15 is at an angle of 30 degrees. With this configuration, the marker lamp 100 can obtain a visible range of 120 degrees forward by the four light emitters 15.

Each light emitting body 15 is provided on a base 19 made of resin (for example, polycarbonate or the like). The pedestal 19 is provided with a recess 191. At this time, the concave portion 191 is formed such that the first light emitter 15a and the fourth light emitter 15d have an elevation angle γ of 5 degrees, and the second light emitter 15b and the third light emitter 15c have an elevation angle β of 10 degrees. Is formed. With this configuration, of the four light emitters, the two light emitters 15a and 15d disposed outside have an elevation angle of 5 degrees, can be viewed from a distance, and can be viewed inside. The two light-emitting bodies provided have an elevation angle of 10 degrees and can be viewed from a short distance. The pedestal 19 is fixed to a fixing plate 23 made of resin (for example, polycarbonate).

The fixing plate 23 is formed of a disk-shaped flat plate, and has a configuration in which a flange 233 is formed on the periphery when the pedestal 19 is fixed. The number of blinks of each light emitting body 15 is 60 to 80 times per minute. The control of the blinking, lighting, and turning off of each light emitter 15 is performed by the control unit 17.

The control unit 17 controls lighting and extinguishing according to the numerical value of the generated voltage of the solar panel 11. That is, a sensor is provided for detecting the amount of sunlight generated by the solar panel 11, and the detected amount from the sensor is input to the control unit 17. The control unit 17 has a comparison circuit for comparing the input voltage value with the set voltage value. For example, when the detection value (power generation amount) from the sensor becomes smaller than the specified value, it is determined that the light has become dark, and the light emitter 15 is turned on at the set number of blinks. When the detected value is larger than the specified value, it is determined that the day is during the day, and the light emitter 15 is turned off.

The control of the control device will be described with reference to a control flow shown in FIG. The process starts at step S10, compares the power generation value input at step S11 with the set value, and if the input value is large (YES), proceeds to step S12 to turn off the light emitting unit. Then, the process returns to step S11 and repeats the determination. If the value input in step S11 is smaller than the set value (NO), the process proceeds to step S13 to turn on the light emitting unit.

The light emitting section 10 configured as described above is covered with a dome-shaped cover section 20. The cover section 20 is made of a transparent polycarbonate resin, and a surface facing the light emitting body 15 is a lens body 25 (for example, a Fresnel lens). The cover 20 is fixed to the flange 233 of the fixing plate 23 by a fixing means such as an adhesive.

The disk-shaped mounting portion 50 includes an engaging portion 51 having a substantially L-shaped cross section and a flat-plate-shaped mounting body 53. The engaging portion 51 is connected to the flange 233 of the light emitting unit 10 via a waterproof packing 60. It is engaged and fixed. A plurality of screw holes 55 are formed in the mounting portion 50 at a plurality of locations.

A method of attaching the thus configured marker light 100 to an object to be attached will be described. For example, when the indicator light 100 is fixed to the laver shelf 200, the laver shelf 200 is sandwiched between the mounting plate 50 of the marker light 100 and the holding plate 70 as an attachment part. Then, the screw hole 55 of the mounting plate 50 and the holding plate 70 are fastened with the bolts 80 and the nuts 85, so that the marker light 100 can be mounted at a desired position of the laver shelf 200.

As described above, since the light emitting section 10 is covered with the dome-shaped cover section 20, the marker lamp 100 has an anti-wind wave resistance expected when installed on a marine facility such as a laver shelf. Shock can be reduced. It also has the function of washing away the salt adhering to the surface of the sign lamp when it dries with raindrops and waves. Further, by applying a zirconia silicon-based ceramic coating agent to the entire surface of the cover portion 20 and the mounting plate 50, a water-repellent film is formed, and the nonflammability, weather resistance, and corrosion resistance can be improved.

The number of times the light-emitting body 10 blinks is classified as a flashlight if the number of flashes is 120 or more per minute by the Maritime Collision Prevention Law. You are. The direction of light emission is set at an angle of 120 degrees to avoid confusion with landmarks, especially on roads. In addition, when used for fixed nets, such as large nets installed on the sea, or for marking offshore dikes, three or four marker lights will be radiated at one location so as to cover all directions. As a result, a 360-degree visible range can be obtained with the plurality of light emitters. In addition, the amount of power generated by the solar panel and the amount of power stored in the lithium battery, etc., are calculated based on the average amount of sunshine, even if there is no sunshine for two weeks after fine weather all day, for example, even if rainy or cloudy weather continues, Light emission is possible.

Next, another mounting method of the marker light will be described with reference to FIG. The mounting method shown in this embodiment shows a case where the marker lamp of the present invention is mounted on a support. A column mounting portion 750 having an L-shaped cross section is hung down at the center of the holding plate 700 as a mounting component. The L-shaped bent portion of the support mounting portion 750 is arranged along the corner of the support (not shown) and is held between the first holding member 770 and the second holding member 780. The first holding member 770 includes a bent portion 771 that can be superimposed on a corner portion (L-shaped bent portion) of the column mounting portion 750, and a plate-shaped retaining portion 773, 775. The second holding member 780 has a bent portion 781 that can be overlapped at the corner of the column and overlapped portions 783 and 785 that overlap with the holding portions 773 and 775 of the first holding member 770.

Then, the holding plate 700 is placed on the upper end of a pillar such as a marine facility, and the pillar mounting part 750 is overlapped with the corner of the pillar. Further, the column mounting portion 750 is held between the first holding member 770 and the second holding member 780 via the column, and the three members are fastened with fasteners such as bolts and nuts. Then, the marker lamp 100 is mounted on the holding plate 700 by the fasteners 80 and 85.

As described above, even when the attached portion is a column, the attachment can be easily performed. Also, in this embodiment, an example is shown in which the light emitting section is installed at the mounting section by the mounting means, but the light emitting section is installed by embedding it in a concrete section such as a seawall, a breakwater, an offshore breakwater, etc. of a specific fishing port or a sightseeing spot, and is installed at night.
