Description

  The present invention relates to an auxiliary light for enabling a ship to safely berth at a port or other quay at night.

  Conventionally, auxiliary lights called quay beacon lights have been installed on the quay so that ship operators can safely berth at night. It was designed to be recognized by the light from this auxiliary light. And this auxiliary lamp as shown in, for example, Patent Document 1 has been proposed.

JP 9-203027 A

  However, due to the recent increase in size of container ships and the like, such auxiliary lights cannot visually recognize the light emitted from the auxiliary lights just before the quay, making it difficult to work at night. This is because in the case of the auxiliary light, light in two different directions is irradiated from the horizontal direction and the direction inclined by 20 ° to 50 ° with respect to the vertical plane. As it arrives, the location of the bridge (bridge) is high, resulting in a blind spot where both lights in two different directions cannot be seen, making it impossible to see the light in two different directions from the ship, and the distance between the quay and the ship. This is because the situation is difficult to grasp.

  Also, when installing the above auxiliary lights on the existing quay, the construction work is large, such as foundation work for installation and power supply, etc., so it cannot function sufficiently as auxiliary lights and is almost popular. There is no current situation.

An object of the present invention is to eliminate such drawbacks, and is a projection window capable of emitting horizontal light from a light source and a projection capable of emitting vertical light from a light source. A berthing lamp in which a window is attached to one case, and a light emitting diode that emits light in the horizontal direction and a light emitting diode that emits light in the vertical direction are separately provided in the case so that each of them is turned on. some of the light to is characterized in the Turkey be irradiated tilt seaward.
According to this docking light, you can see the horizontal light that is lit from a distance between the ship and the quay, and from the time when the distance to the quay is relatively close to the time when the ship is completely berthed. Since the vertical light that is lit can be seen continuously, it is possible to berth more safely. In particular, from the time when the distance to the quay is relatively close to the time when the berth is completely touched, light in a direction inclined to the sea side can be seen in addition to the light in the vertical direction. It can be recognized and can berth more safely.

Since the light source for illuminating the two directions of light of different horizontal and vertical directions is a light emitting diode, less the cross-sectional core, do not take more than usage costs power consumption reduced, thereby prolonged use.

It is desirable to flash the respective light emitting diode for irradiating a light emitting diode and the vertical direction of the light irradiating the horizontal direction of the light. In this way, you can see the flashing horizontal light from a distance between the ship and the quay, and it also flashes from when the distance to the quay is relatively close until it completely touches the berth. You can see the light in the vertical direction constantly, so you can touch the shore more safely. In particular, by flashing the light, the operator can be alerted and can be aware that he is approaching the quay.

  It is desirable to make the light color of the light emitting diode that emits light in the horizontal direction different from the light color of the light emitting diode that emits light in the vertical direction. In this way, the operator can recognize that he is approaching the quay from the difference in light color between the light in the horizontal direction and the light in the vertical direction.

  It is desirable to make the blinking rhythms of the light emitting diode that emits light in the horizontal direction and the light emitting diode that emits light in the vertical direction different. In this way, the operator can recognize that he is approaching the quay from the difference in the blinking rhythm of the light in the horizontal direction and the light in the vertical direction.

  It is desirable to adopt a solar cell system as the power source of the light emitting diode and further mount a secondary battery. In this way, not only a land power supply is unnecessary, but there is no need for external power supply by an independent power supply system, and wiring and piping are also unnecessary.

  It is desirable to attach a raising material to the left and right of the lower surface of the case in the front-rear direction so that the space under the case between the two raising materials becomes a cavity. If it does in this way, since the water which flows on the quay flows down to the sea from the cavity part under a case, the drainage of a quay can be improved.

  It is desirable that the size of the case be a size that can be installed between the car stops provided on the quay. If it does in this way, a docking light will become compact and the occupation area can be made small.

According to the first aspect of the present invention, the light in the horizontal direction that is lit can be visually recognized from a distant place where there is a distance between the ship and the quay. Because the vertical light that is lit during this period can be seen continuously, it is possible to berth more safely. In particular, from the time when the distance to the quay is relatively close to the time when the berth is completely touched, light in a direction inclined to the sea side can be seen in addition to the light in the vertical direction. It can be recognized and can berth more safely.

Since the light source is a light emitting diode, less the cross-sectional core, do not take more than usage costs power consumption reduced, thereby prolonged use.

According to the invention described in claim 2, the blinking horizontal light can be visually recognized from a distant place where there is a distance between the ship and the quay, and from when the distance to the quay becomes relatively close, until the pier is completely touched. Since the vertical light that flashes during this period can be seen continuously, it is possible to berth more safely. In particular, by flashing the light, the operator can be alerted and can be aware that he is approaching the quay.

According to the invention described in claim 3, it can be recognized that the quay is approaching from the difference in light color between the light in the horizontal direction and the light in the vertical direction.

According to the invention of claim 4, it can be recognized that the quay is approaching from the difference in the blinking rhythm of the light in the horizontal direction and the light in the vertical direction.

According to the fifth aspect of the present invention, not only a land power supply is unnecessary, but there is no need for external power supply by an independent power supply system, and wiring and piping are also unnecessary.

According to invention of Claim 6 , since the water which flows on a quay flows down into the sea from the cavity part under a case, the drainage of a quay can be improved.

According to the seventh aspect of the present invention, the docking lamp becomes compact and its occupied area can be reduced.

An embodiment of a docking light according to the present invention will be described with reference to the drawings. FIG. 1 shows an example of a case of a landing light according to the present invention, and FIG. 2 shows an example of a landing light using this case.
The case 1 of the docking light A is a so-called bowl-shaped one, and can be made of, for example, an aluminum alloy. When the case 1 is made of this material, it is not only difficult to be corroded but also excellent in strength.

  On the front surface of the case 1, a light projection window 2 that can irradiate light from the light source in the horizontal direction is provided in the vertical direction. Further, on the upper surface of the case 1, a light projection window 3 that can irradiate light in the vertical direction from the light source is provided in the horizontal direction. Both light projection windows 2 and 3 can be formed, for example with an acrylic board.

  In correspondence with the two light projection windows 2 and 3, a light emitting diode 2 a that emits light in the horizontal direction and a light emitting diode 3 a that emits light in the vertical direction are arranged in the case 1. 2B shows a case where four light emitting diodes 2a and 2a are arranged for one light projection window 2, and FIG. 2A shows a case where one light emission window 3 is provided. In this example, two light emitting diodes 3a and 3a are arranged.

A solar cell panel 4 is provided on the upper surface of the case 1, and various devices 4a to be attached to the solar cell panel 4 are attached as shown in FIG. The solar cell panel 4 is indispensable for adopting a solar cell system as a power source for the light emitting diodes 2a and 3a. By adopting this system, a land power source becomes unnecessary.
When the light emitting diodes 2a and 3a are used as the light source of the berthing light A, there is little disconnection, less power consumption, no use cost, and long-term use.

In the case where the docking lamp A is placed on the quay B, and is far in distance between the ship S and the quay B, visible light L ₁ in the horizontal direction as shown in FIG. 5 (a), between the time the distance is relatively close to the ship S and the quay B until completely berthing can also constantly visible vertical light L ₂ as shown in Figure 5 (b). Therefore, there is no blind spot area as in the prior art, and it is possible to safely berth while constantly recognizing the sense of distance between the quay B and the ship S.

The light emitting diode 2a for irradiating the light in the horizontal direction and the light emitting diode 3a for irradiating the light in the vertical direction may be provided separately, and each of them may be lit, but each may be blinked. Thus, visible light L ₁ of the horizontal direction of flashing from a distance which is the distance between the ship S and the quay B, until completely berthed from the time the distance is relatively close to the quay B since also it constantly viewing the vertical direction of the light L ₂ the flashing between, can be more safely berthing. In particular, the operator can be alerted by blinking the light, and can be aware that he is approaching the quay B.

  In addition, the light color of the light emitting diode 2a that emits light in the horizontal direction can be made different from the light color of the light emitting diode 3a that emits light in the vertical direction. In this way, the boat operator can recognize that he / she is approaching the quay B from the difference in light color between the light in the horizontal direction and the light in the vertical direction.

  Further, the blinking rhythm of the light emitting diode 2a that emits light in the horizontal direction and the light emitting diode 3a that emits light in the vertical direction can be made different. In this way, the boat operator can recognize that he is approaching the quay B from the difference in the blinking rhythm of the light in the horizontal direction and the light in the vertical direction.

Furthermore, some of the vertical direction of the light L ₂ is are be irradiated inclined to the sea side. In this way, from the time when the distance to the quay B becomes relatively short until it completely touches the pier, light in a direction inclined to the sea side can be visually recognized in addition to the light L _{2 in the} vertical direction. You can recognize that you are approaching the shore, and can berth more safely.

  Here, a case where a solar cell system is adopted as a power source of the light emitting diodes 2a and 3a and a secondary battery indicated by a reference numeral 5 in FIG. 3 is mounted is illustrated. When the secondary battery 5 is mounted, not only a land power supply is unnecessary, but there is no need for external power supply by an independent power supply system, and wiring and piping are also unnecessary. In FIG. 3, each device in the case 1 is shown with the side cover of the case 1 removed.

  On the other hand, the case where the raising materials 6 and 6 are attached to the left and right of the lower surface of the case 1 in the front-rear direction and the bottom of the case 1 between the raising materials 6 and 6 is a cavity is illustrated here. . In this case, since the water flowing on the quay B flows down to the sea from the hollow portion 7 (see FIG. 4) under the case 1, drainage of the quay B can be improved. The raising material 6 can be made of stainless steel, for example.

  Further, here, the case 1 is illustrated in the case where the size of the case 1 is set to a size that can be installed between the car stopper C and the car stopper C provided on the quay B. In this case, the berthing light A becomes compact, and the occupied area can be reduced. Therefore, as shown in FIG. 4, the compact landing light A can be installed between the car stop C and the car stop C, and the installation on the existing quay wall is easy and easy to spread.
