  The present invention relates to a lamp for a light emitting buoy and a light emitting buoy.

Japanese Utility Model Publication No. 3-53399 Japanese Patent No. 274000945 Japanese Utility Model Publication No. 64-39195

  In Patent Document 1, a support column that supports a lamp is configured by a double cylinder including a cylindrical support body and a cylindrical transparent cylinder provided with a gap around the support body. There is disclosed a buoyant lamp in which solar cells are arranged in a hexagonal column shape in a gap therebetween and a storage battery is accommodated inside a support. Illustrative examples of the lamp include a halogen lamp, an incandescent bulb, and a light emitting diode (LED) housed in a transparent lamp.

  Patent Document 2 discloses a cylindrical mirror body, a large number of light emitting diodes arranged radially in two stages on the outer periphery, a cylindrical transparent case surrounding them, and a horizontal arrangement at the upper end of the mirror body. There is disclosed a buoyant lamp including a solar cell. In this buoyant lamp, the light emitting unit described above is arranged at the upper end of the column body, and is used by floating on the sea surface with a floating body provided at the lower part of the column body.

  Patent Document 3 discloses a saddle-type flashing light emitting buoy in which a solar cell and a light emitting diode are provided substantially horizontally at the upper end, a storage battery is accommodated at the lower end, and the light emitting diode flashes.

  Since the buoyant lamp of Patent Document 1 is configured to incorporate a solar cell or a storage battery into a support column that supports the lamp, the lamp at the upper end can be made small and stable overall. Moreover, since the lamp is at the upper end, the visibility is high. However, the space for housing the solar cell is reduced, and the power generation amount is reduced because the space is close to the water surface. This reduces the amount of light emitted from the lamp.

  In the buoyant lamp of Patent Document 2, since the solar cell and the light emitting diode are accommodated in one transparent case, an airtight structure is easily obtained, and the solar cell is arranged horizontally at the upper end, so that the amount of power generation is large. . However, since the solar cell covers the upper side of the light emitting diode, it is difficult to visually recognize the light emitting diode when viewed from a high position.

  In the light emission blinking buoy of Patent Document 3, the above-described problems of the buoyant lamps of Patent Document 1 and Patent Document 2 are solved. However, since the light emitting part and the solar cell are arranged in the immediate vicinity of the water surface, it becomes difficult to see because it gets wet with seawater, and there is a risk that a drifting object may hit the light emitting part.

  The present invention eliminates the problems of the above-described conventional buoyant lamp, the visibility of the light emitting part is high, the amount of power generation can be increased, and the lamp for the light emitting buoy that can construct the airtight structure relatively easily. It is a technical issue to provide. Furthermore, the present invention has a technical problem to provide a light emitting buoy having the above-mentioned advantages, and further, the lamp is high from the surface of the sea or the water, the light of the lamp is easily visible, and the lamp is not likely to collide with drifting objects.

  A light emitting buoy lamp according to the present invention (Claim 1) is a lamp provided at an upper end of a light emitting buoy, and includes a base, a cylindrical support member rising from the base, and a support member below the support member. A plurality of solar cells arranged so as to surround, a power storage means for storing electric power obtained by the solar cells, a plurality of light emitting diodes attached in an annular shape to the outer peripheral surface of the support member, and detecting sunlight Control that causes the power storage means to store the power generated by the solar cell when the light sensor detects sunlight, and causes the light-emitting diode to emit light when the light sensor does not detect sunlight. And a transparent cylindrical cover that is airtightly attached to the base so as to cover the light emitting diode and the optical sensor.

  In such a light emitting buoy lamp, it is preferable that the base has an annular support surface that extends horizontally outward from the lower end of the support member, and the solar cell is mounted on the support surface ( Claim 2). In this case, it is preferable that the solar cell has a thin donut-like shape and a plurality of outer peripheral portions thereof are pressed against the base by a mounting block (Claim 3). A cylindrical second support member is continuous below the support member, the solar cell is attached to the outer peripheral surface of the second support member, and the cover is supported by the first support member and the second support member. The member may be covered airtightly (Claim 4).

  The light emitting buoy according to the present invention (Claim 5) is characterized by comprising any one of the above-mentioned lamps, a column supporting the lamp at the upper end, and a float attached to the lower part of the column.

  A lamp for a light emitting buoy according to the present invention (Claim 1) forms an airtight container in which an airtight container is maintained by a base and a transparent cylindrical cover attached to the base, and a light emitting diode and a control unit are formed therein. Is housed. Therefore, the airtight structure is simple, the number of parts is small, and the manufacture is easy. Further, since the solar cell is arranged not to support the support member but to surround the support member below the support member, the area can be increased and the amount of power generation is increased. As a result, the amount of light emission can be increased. Furthermore, since the solar cell is provided below the support portion that supports the light emitting diode, the light generated by the light emitting diode is not disturbed by the solar cell and has high visibility.

  In such a lamp, when the base has an annular support surface that extends horizontally outward from the lower end of the support member, and the solar cell is mounted on the support surface (Claim 2), Since it is easy to receive sunlight in a time zone where the amount of light is strong, the amount of light emitted by the solar cell is large. Moreover, the solar cell does not hinder the visibility of the light emitting diode.

  When the solar cell has a thin donut-like shape and a plurality of outer peripheral portions are pressed against the base by a mounting block (Claim 3), the area of the solar cell can be increased, and Installation work is easy.

  A cylindrical second support member is continuous below the support member, the solar cell is attached to the outer peripheral surface of the second support member, and the cover includes the first support member and the second support member. When covering airtightly (Claim 4), an installation space can be made small, maintaining the area of a solar cell.

  Since the light emitting buoy of the present invention (Claim 5) is provided with any of the above-mentioned lamps at the upper end of the support column, the lamp equipped with the electric system can be protected from water droplets scattered from the water surface. Furthermore, since the lamp is much higher than the water surface, visibility is high.

  Next, embodiments of a lamp and a light emitting buoy according to the present invention will be described with reference to the drawings. 1 is a partially sectional side view showing an embodiment of a lamp of the present invention, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIGS. 3a and 3b are enlarged views of portions A and B in FIG. 4 is an electric circuit diagram showing an embodiment of the control unit of the lamp of FIG. 1, FIG. 5 is an electric circuit diagram showing another embodiment of the control unit of the lamp of FIG. 1, and FIG. 6 is another example of the lamp of the present invention. FIG. 7 is a sectional view taken along line VII-VII in FIG. 6, FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 6, and FIG. 9 is still another embodiment of the lamp of the present invention. FIG. 10 is a side view showing an embodiment of a light emitting buoy according to the present invention, and FIG. 11 is a plan view showing a use state of the light emitting buoy according to the present invention.

  A lamp 10 shown in FIG. 1 includes a sealed container including a base 11 and a bottomed cylindrical transparent case 12 that is airtightly fixed to the base, and an internal structure accommodated in the sealed container. . The base 11 has a disk shape having a diameter about 2 to 3 times that of the case 12 (see FIG. 2), and a cylindrical support protrusion 13 for supporting the case 12 is integrally provided at the center. The base 11 is made of metal, in particular aluminum. On the upper surface of the base 11, a thin plate-shaped donut-like solar cell panel 14 having a hole through which the support protrusion 13 is passed in the center is attached (see FIG. 2).

  Inside the case 12, cylindrical support members 15 and 16 fixed to the base 11 are arranged. The support member includes a large-diameter lower support member 15 and a small-diameter upper support member 16, and the upper support member 16 is fixed to the upper end of the lower support member 15 with a screw or the like. However, it is also possible to mold both together. The solar cell panel 14 is formed by integrally arranging a plurality of solar cells 17 radially. A number of light emitting diodes 18 are attached around the upper support member 16, and a storage battery 19 and a control unit 20 are accommodated in the lower support member 15.

  A female screw 13 a is formed on the inner surface of the support protrusion 13 of the base 11 and is screwed with a male screw formed on the outer periphery of the lower end of the case 12. A cylindrical portion 22 for fixing the column 21 protrudes from the lower surface of the base 11. A female screw 22 a is formed on the inner periphery of the cylindrical portion 22, and is screwed with a male screw on the outer periphery of the column 21. A sealing material 23 such as an O-ring is interposed between the upper end of the support protrusion 13 and the case 12 so as to be airtight. On the outer surface side near the lower end of the case 12, a step portion 24 with which the sealing material 23 abuts is formed. The base 11 is usually formed of a metal such as aluminum, but may be made of a synthetic resin. In the case of synthetic resin, it is screwed to a flange or the like provided at the upper end of the column 21. A male screw may be formed on the outer periphery of the cylindrical portion 22 and screwed into the inner periphery of the column 21.

  The case 12 has a bottomed cylindrical shape with a closed upper end, and is a transparent cylindrical member made of synthetic resin such as acrylic resin or polycarbonate, glass, or a synthetic resin sheet and glass. The top surface of the case 12 is hemispherical, but may be flat. Further, the case 12 can be formed in a rectangular tube shape. By making the case 12 transparent, the light emitting diode 18 can be visually recognized from the outside. The case 12 may be a cylinder, and a transparent lid may be provided on the upper end thereof. The lid is also preferably transparent, but may be a metal such as aluminum.

  On the upper surface of the base 11, the lower surface of the lower support member 16 is fixed from below the base 11 with screws 26 or the like. In this embodiment, the lower support member 15 has a bottomed cylindrical shape, and is cylindrical as shown in FIG. The upper support member 16 has a smaller diameter than the lower support member 15, and includes a connecting portion (flange) 27 that fits with the upper end of the lower support member 15 at the lower end. The upper support member 16 is substantially cylindrical except for the flange 27. It is good also as a rectangular tube type. The flange 27 is fixed to the upper end of the lower support member 15 with a screw or the like. Thus, by making the diameter of the upper support member 16 smaller than the diameter or passing of the lower support member 15, it is difficult to hit the light emitting diode 18 when the case 12 is attached to or detached from the base 11.

  The support members 15 and 16 can be integrally formed from a synthetic resin such as polyvinyl chloride or polyethylene. However, it may be divided into two or more parts, and may be assembled by bonding. It may also be made of metal. The overall height of the support members 15 and 16 is preferably set such that there is a gap between the upper end and the inner surface of the case 12. However, the protrusion provided on the upper end or the outer periphery may be brought into contact with the case 12.

  As described above, the solar battery panel 14 is thin and has a donut shape. In this embodiment, the solar cell panel 14 uses a plurality of, for example, 10 to 20, rectangular solar cells 17 arranged radially on a substrate and connected in series or in parallel by wires 17a. One solar cell 17 may be a module in which a plurality of cells are combined. A solar cell may be further provided around the lower support member 15, thereby increasing the amount of power generation. In the above embodiment, as shown in FIG. 2, the solar cell panel 14 has a single donut shape, but two or three or more semicircular or fan-shaped solar cell panels may be combined. Good. Lead wires for taking out electric power from the solar cell panels 14 penetrate the lower support member 15 and are connected to the internal control unit 20.

  The solar cell panel 14 is fixed to the base 11 by a mounting block 27 shown in FIG. The mounting block 27 has a rectangular parallelepiped shape with a lower portion cut out in a rectangular shape, and a cushioning material 28 such as rubber is provided on the lower surface of the cutout portion to protect the solar cell panel 14. A female screw 29 is formed on the mounting block 27 in the vertical direction. And it is fixed with the screw 30 inserted from the lower side of the base 11. The upper end of the female screw 29 is screwed with a lower end of a bird rod 31 that protrudes upward so that the bird does not stop. The bird guard 31 may be directly attached to the base 11. Although not shown, if the bird guard 31 is provided close to the case 12, it is possible to prevent the bird from stopping on the case 12.

  As shown in FIG. 3a, a plurality of the light emitting diodes 18 are arranged on a rectangular substrate 32, for example, one in each of the upper, lower, left and right corners, and one in the center. As shown in FIG. 2, the number of the substrates 32 is eight, for example, and 40 light emitting diodes 18 can be arranged on the circumference. Two or more substrates 32 may be arranged vertically. Further, about 1 to 2 pieces can be provided on one substrate, and about 12 to 20 pieces can be arranged around the upper support member 16 in a horizontal row. For a small lamp (see FIG. 9), which will be described later, such a lamp with a reduced amount of light can also be used. Lead wires of the respective light emitting diodes 18 are connected in parallel by a printed wiring provided on the substrate 32, and pass through the upper support member 16 and are connected to the control unit 20 inside the lower support member 15.

  A storage battery 19 is accommodated in the lower support member 15 as power storage means. As the storage battery 19, a rechargeable battery such as a nickel metal hydride battery (Ni-HM battery), a nickel cadmium battery, or a lithium battery is used. An electric double layer capacitor can also be used. However, when a large number of light emitting diodes are lit, it is preferable to use a storage battery having a high electric capacity such as a nickel metal hydride battery and capable of charging and discharging. This storage battery 19 is for storing the electric power generated by the solar battery 17 during the day and for illuminating the light emitting diode 18 at night.

  One of the substrates 32 is provided with a photosensor (phototransistor 39 in FIG. 4) such as a photodiode or a phototransistor. This optical sensor switches the connection between the solar battery 17 and the storage battery 19 to the connection between the storage battery 19 and the light emitting diode 18 when the surroundings become dark. The output of the light sensor switches on / off of the light emitting diode 18 via a relay (symbol L in FIG. 4). The optical sensor is provided in the vicinity of the upper end opening inside the upper support member 15. As a result, the ship's illuminating light does not directly hit the light sensor at night, and malfunctions are unlikely to occur. However, a part of the solar cell 17 may be transparent and disposed inside thereof, or a hole may be formed in the substrate of the solar cell 17 so as to penetrate the hole. Moreover, it can replace with an optical sensor and can also employ | adopt the control method which detects the electric power generation amount of the solar cell 17, and switches when the electric power generation amount becomes smaller than a setting amount.

  FIG. 4 shows an electric circuit of the control unit 20 for controlling the solar cell 17, the light emitting diode 18, the storage battery 19, and the phototransistor 39 as an optical sensor. Such an electric circuit is printed on a substrate and is housed in the lower support member 15 together with the storage battery 19. Thereby, the control part 20 can be protected from sunlight. In this electric circuit, the solar cell 17 is connected to the storage battery 19 in parallel.

  The positive line 35 of the solar cell 17 is connected to the positive side of the storage battery 19 via a Schottky barrier diode 36 in order to prevent backflow from the storage battery 19 to the solar battery 17 side. The minus side wire 37 is connected to the minus side of the storage battery 19 as it is. A Zener diode 38 is interposed between the plus line 35 and the minus line 37 to prevent overcharging. The symbol SW is a switch for turning off the entire circuit in the summer season when nori is not cultivated.

  A phototransistor 39 is used as an optical sensor. The collector of the phototransistor 39 is connected to the plus line 35, and the emitter is connected to the minus line 37 via the resistor R1. The output signal of the phototransistor 39 is connected to the base of a transistor TR that controls blinking of the light emitting diode 18 via a blinking circuit including a capacitor C1 and a resistor R1.

  The output of the transistor TR repeats ON / OFF every short time, for example, every 1 to 10 seconds, according to a time constant determined by the blinking circuit. Thereby, the light emitting diode 18 blinks. In addition, the time when the light emitting diode 18 is shining is made shorter than the time when it is off. Thereby, power consumption can be reduced. The light emitting diode 18 is connected in parallel to the storage battery 19. That is, the storage battery 19 is a power source for the light-emitting diode 18 and also a power source for a control circuit for outputting a signal for switching on / off the light-emitting diode 18 and a signal for blinking.

  FIG. 5 is an electric circuit diagram showing another embodiment of the control unit 20, in which the light emitting diode 18 is turned on / off via a relay L driven by a power transistor PTR. In this electric circuit, the solar battery 17 is divided into a first solar battery 17a and a second solar battery 17b, and the storage battery 19 is divided into a first storage battery 19a and a second storage battery 19b, and the first solar battery 17a is respectively a first storage battery. 19a is connected in parallel, and the second solar cell 17b is connected in parallel with the second storage battery 19b. The reason for this division is to drive the light emitting diode 18 via the relay L on the one hand and to drive the phototransistor 39 on the other hand.

  The output side of the power transistor PTR is connected to operate the coil Lc of the normally open relay L. The contact Ls of the relay L is closed when the coil Lc is energized. Thereby, ON / OFF of the light emitting diode 18 can be switched.

  In the lamp 10 configured as described above, since the base 11 and the case 12 are joined in an airtight or liquidtight manner, the internal electrical components are protected from seawater and sea breeze. And since the place to seal is only the connection part of case 12 and base 11, there are few places to seal. Therefore, it is easy to manufacture and has a high sealing function. Further, the light emitting diode 18 is integrally provided on the cylindrical support member (upper support member 16), and the storage battery 19 and the control unit 20 are accommodated inside the support member (lower support member 15). Other electrical related items can be grouped together, and manufacturing is easy.

  The lamp 40 in FIG. 6 includes a case 12 having two stages of an upper case 12a and a lower case 12b, and a solar cell 17 attached directly around the lower support member 15. The reason why the case 12 is two-staged is to share the small lamp 41 shown in FIG. 9 with parts, and can be a single-stage case. As shown in FIG. 7, the lower support member 15 has a cylindrical shape with a pentagonal cross section, and has five solar cells 17 attached thereto. Further, the upper support member 15 has a cylindrical shape as shown in FIG. 8 and has eight substrates 32 attached thereto. Since the other points are substantially the same as the lamp 10 of FIG. 1, the same parts are denoted by the same reference numerals and description thereof is omitted. The lamp 40 can reduce the area of the base 11 and the entire lamp 40 can be reduced.

  A small lamp 41 shown in FIG. 9 has an upper case 12a in the lamp 40 of FIG. 6 attached to a base 11 to form a sealed container, and a lower support member 15 and an upper support member 16 similar to those in FIG. The solar cell 17 is disposed on the outer peripheral surface of the lower support member 15, and the light emitting diodes 18 are arranged on the upper support member 16 in one or two stages. The storage battery, control unit, optical sensor, and the like are the same as in FIG. Since the number of the light emitting diodes 18 is small, the capacity of the solar cell 18 or the storage battery is small. And the case 12a etc. can be shared with the lamp 10 of FIG. The number of the light emitting diodes 18 may be about 4 to 6 in the circumferential direction and about 2 steps in the vertical direction. In that case, the power consumed by the light emitting diode is small, and the storage capacity may be small. Therefore, an electric double layer capacitor can be used as the power storage means.

  FIG. 10 shows a light emitting buoy 42 using the lamp 10 of FIG. As the lamp, the lamp 40 in FIG. 6 or the small lamp 41 in FIG. 9 may be used. The lamp 10 is fixed to the upper end of the column 14, and a float 43 is attached around the lower part of the column 14. In this embodiment, the float 43 is configured as an annular body having a hole 44 penetrating the support column 14 at the center. However, a plurality of floats may be fixed around the column 14. The annular float 43 or each float is preferably made of a foamed resin having durability against seawater such as foamed urethane.

  A connection ring 45 is provided at the lower end of the support column 14, and a weight 47 is connected to the connection ring 45 via a connection line 46 such as a chain, a wire, or a string. By sinking the weight 47 on the sea floor, the lamp 10 can be floated at a predetermined position on the sea surface 48 so as not to be washed away. The connecting cable 46 may be connected to a nori culture net or the like.

  In the light emitting buoy 42 used as described above, since the light sensor (reference numeral 39 in FIG. 4) detects sunlight during the daytime, the light emitting diode 18 is not lit and the power generated by the solar cell 17 is supplied to the storage battery 19. Stored. The solar cell 17 directly receives sunlight shining from above and generates power. In the light emitting buoy in which the solar cell 17 is provided on the support member 16, even light reflected from the sea surface 48 generates power. Moreover, since the solar cell 17 is arrange | positioned in the perimeter so that the support member 16 may be surrounded, the solar cell 17 generate | occur | produces strong electric power by receiving direct sunlight even in the time zone when the sun inclined.

  Then, at night, when the light sensor 34 hardly detects sunlight, the contact of the relay L is turned ON, and the light emitting diode 18 is lit by the power stored in the storage battery 19. Since the light emitting diodes 18 are arranged all around, they can be viewed from any direction. Moreover, since it is arrange | positioned in multiple steps up and down, visibility is good and it is easy to distinguish from the light of a land. Furthermore, since there is no obstruction such as solar cells at the upper end, visibility is high even when looking down from a nearby ship.

  As described above, the light emitting buoy 42 can be automatically switched on / off without performing any operation of lighting / extinguishing. Moreover, since the electric power generated by the solar battery 17 is stored in the storage battery 19 and the light emitting diode is lit by the electric power, it is not necessary to replace the battery. Further, the light-emitting diode 18 has extremely high durability as compared with a light bulb or the like. In particular, when the light-emitting diode 18 is blinked, the light-emitting diode 18 is further improved in durability by increasing the interval between lighting to about several seconds. Therefore, it is almost maintenance-free. For example, when used as a light emitting buoy to indicate the position of the laver culture net, it is only necessary to leave it on the sea surface during the laver culture season, until after the next aquaculture period, Just go to land and perform the necessary maintenance. The switch (SW in FIG. 4) is turned off during periods when it is not used.

  FIG. 11 shows an embodiment of a position display device 50 for a laver culture net 49 using a plurality of the light emitting buoys 42. The position display device 50 includes a large light emitting buoy 42 having the lamp 10 shown in FIG. 1 at four corners of a nori culture net 49 and a small lamp 41 shown in FIG. A plurality of small light emitting buoys 51 are arranged. In this case, the connecting rope 46 of the light emitting buoys 42 and 51 is connected to the aquaculture net 49.

  Although the diameter of the upper support member 16 is smaller than the diameter of the lower support member 15 in the embodiment, it may be the same diameter. In that case, the support member can be easily manufactured by cutting the pipe. In addition, the upper support member 16 and the lower support member 15 are each formed in a cylindrical shape or a rectangular tube shape, but may be tapered or a truncated pyramid shape so that the upper diameter is reduced. Moreover, it can also be set as a continuous integral taper surface or a truncated pyramid shape. In this case, in a lamp provided with a solar cell on the lower support member 15, the solar cell 17 faces obliquely upward, so that the amount of power generation increases. Further, since the light emitting diode 18 is also obliquely upward, visibility is improved. Moreover, the surface of the range which supports the light emitting diode 18 of a supporting member can also be made into a mirror surface. In that case, the light from the light emitting diode 18 is emitted forward without waste.

  The portion of the support member 16 that supports the solar cell 17 may be further divided into an upper portion and a lower portion, and a surface that faces obliquely upward may be provided on the upper portion, and a surface that faces obliquely downward may be provided on the lower portion. In that case, the solar cell provided at the upper part so as to face obliquely upward becomes easy to receive the sunlight directly, and the solar cell provided so as to face the lower part of the lower part becomes easy to receive reflected light from the sea surface.

  In the above-described embodiment, the light emitting diodes 18 are arranged on the substrate 32, but may be directly provided on the surface of the support member 16. However, when the support member 16 is made of a conductive material such as a metal, the light emitting diodes 18 are arranged after providing an insulating layer. The same applies to the solar cell 17. When the light emitting diode 18 is arranged by providing an insulating layer on the metal supporting member 16 having high heat conductivity such as aluminum, the supporting member 16 is cooled by seawater through the base 11 and the support column 14, thereby the light emitting diode 18. Therefore, there is an advantage that the deterioration due to heat generation of the light emitting diode 18 is suppressed and the life is extended.
