Description

  The present invention relates to a stabilizer for a fishing light.

  Fishing boats that capture fish such as squid, mackerel and saury use incandescent and discharge lamps as fish collection lights. In the case of a large ship, it has two generators as the main power supply and auxiliary equipment, so the incandescent lamp and the discharge lamp can be used separately in separate circuits. In most cases, only the main engine is installed.

  For this reason, in the case of a small boat, in order to use both an incandescent lamp and a discharge lamp as a fish collection lamp, it is necessary to connect the incandescent lamp and the discharge lamp in parallel to the output of the main engine.

  By the way, adjusting the brightness of the incandescent lamp is generally handled by making the voltage of the generator significantly variable. Therefore, when the discharge lamp is connected in parallel to the incandescent lamp, it is stable enough to handle this voltage change. A vessel is required. For this reason, the conventional ballast is provided with a low voltage input terminal and a high voltage input terminal on the input side of the ballast in order to cope with the change in the voltage applied to the ballast. These input terminals are set to be switched on the terminal block in accordance with the voltage level.

  However, when the output level of the generator is frequently changed, it is difficult to perform the switching operation at the terminal block each time. As a result, when the incandescent lamp is used together with the discharge lamp, an excessive voltage is applied to the ballast, which may cause a burnout accident.

  For this reason, it has been difficult for small ships that rely only on the main engine to use discharge lamps with higher illuminance efficiency than incandescent lamps for safety reasons, resulting in poor fish collection efficiency.

  The object of the present invention is therefore to provide a stabilizing device for a fishing light which can solve the above-mentioned problems in the prior art.

  In order to solve the above-mentioned problems, according to the present invention, in a fish-collecting lamp stabilizing device comprising a ballast for a discharge lamp having a plurality of input terminals corresponding to input voltages on the input side, the fish-collecting lamp stabilizing device A voltage sensor for detecting a level of a supply voltage to the power supply, and a main relay for switching the connection so that the supply voltage can be connected to any one of the plurality of input terminals. According to the present invention, there is proposed a stabilizing device for a fish collection lamp, wherein the main relay is controlled according to an output, and the supply voltage is applied to an input terminal corresponding to a level of the supply voltage among the plurality of input terminals. .

  According to the present invention, even if the supply voltage level changes, the supply voltage can be applied to the input terminal corresponding to the supply voltage level among the plurality of input terminals of the ballast, following the change. Even when an incandescent lamp is provided, it is possible to effectively prevent an excessive voltage from being applied to the ballast.

  Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a circuit diagram showing an example of an embodiment of a stabilizing device for a fishing light lamp according to the present invention. In the stabilizer 1 for a fish collecting lamp, 2 is a ballast, 3 is a discharge lamp, and an output voltage from a generator (not shown) applied to the power receiving terminals T1 and T2 is supplied to the discharge lamp 3 through the ballast 2, The discharge lamp 3 is configured to emit light. An incandescent lamp 4 is also connected between the power receiving terminals T1 and T2, and the output voltage from the generator is directly applied to the incandescent lamp 4.

  The ballast 2 includes a high voltage input terminal 2A and a low voltage input terminal 2B, and the power receiving terminal T1 is connected to either the high voltage input terminal 2A or the low voltage input terminal 2B by the main relay 5.

  That is, the main relay 5 is composed of a relay coil 5A and a relay switch 5B. A high voltage input terminal 2A and a low voltage input terminal 2B are connected to the contacts a and b of the relay switch 5B, respectively, and a switching piece C of the relay switch 5B is connected to the switching piece C. The power receiving terminal T1 is connected via the wiring L1.

  One end of the relay coil 5A is connected to the power receiving terminal T2, and the other end is connected to the contact b, that is, the low voltage input terminal 2B via the relay switch 6B of the auxiliary relay 6.

  Reference numeral 7 denotes a voltage sensor for detecting the level of the supply voltage supplied between the power receiving terminals T1 and T2, and the voltage sensor 7 determines whether the level of the supply voltage is higher or lower than a set value. It is the composition which becomes.

  The relay coil 6A of the auxiliary relay 6 is connected to the output side of the voltage sensor 7, and when the level of the supply voltage becomes lower than the set value by the voltage sensor 7, the voltage sensor 7 causes a current to flow through the relay coil 6A. The relay switch 6B is closed.

  Since the fish lamp stabilizing device 1 is configured as described above, if the voltage supplied between the power receiving terminals T1 and T2 is the rated voltage, the level of the supply voltage becomes higher than the set value by the voltage sensor 7. Since the voltage sensor 7 does not pass a current through the relay coil 6A, the relay switch 6B is opened. Therefore, since no exciting current flows through the relay coil 5A, the relay switch 5B is switched as shown in the figure, and the supply voltage is applied to the high voltage input terminal 2A. Therefore, a predetermined voltage is applied to the discharge lamp 3.

  On the other hand, if it is determined that the supply voltage supplied between the power receiving terminals T1 and T2 is lower than the set value, the voltage sensor 7 causes a current to flow through the relay coil 6A, so that the relay switch 6B is closed. It becomes. For this reason, an exciting current flows through the relay coil 5A, the relay switch 5B is switched as indicated by a dotted line in the figure, and the supply voltage is applied to the low voltage input terminal 2B. Therefore, a predetermined voltage is applied to the discharge lamp 3 in spite of a decrease in the supply voltage.

  In this way, the terminal connection on the input side of the ballast 2 is automatically switched in accordance with the level change of the supply voltage supplied between the power receiving terminals T1 and T2, so that the brightness of the incandescent lamp 4 is adjusted. Even if this is dealt with by greatly varying the voltage of the generator (not shown), the voltage can be automatically controlled within the rated range of the ballast so that an excessive voltage is not applied to the ballast 2.

  As a result, the discharge lamp 3 can be supplied with electric power within a certain range even when the supply voltage fluctuates greatly, and the incandescent lamp 4 is mixed in the same circuit and the voltage is greatly varied. However, the ballast 2 can be used without affecting the burnout due to the excessive voltage, the damage due to the overcurrent of the discharge lamp 3, and the life.

  Although one embodiment has been described above, the present invention is not limited to this embodiment. For example, instead of the relay switch 6B, a thyristor photocoupler may be used, or a plurality of devices may be used to switch the stage finely.

The circuit diagram which shows an example of embodiment of this invention.
