Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fishing light device used in a fishing boat for catching fish such as pike.
[0002]
[Prior art]
Conventionally, in the fishing of Pacific saury, many fish collecting lights are attached to a plurality of rod-shaped lamps protruding from the periphery of the fishing boat toward the sea, and the fishing lights are repeatedly turned on and blinked to collect the fish in the net. The method of catching is adopted. As such a fish-collecting light, for example, an incandescent light bulb using a filament lamp of about 500 to 750 W (watt), or a lamp having a built-in filament / halogen lamp in the lamp is generally used. About 20 rods are attached to about 20 to 30 rod-shaped lamps, respectively. The present applicant has disclosed a technique relating to a ballast for instantaneously lighting such a lamp (for example, see Patent Document 1).

[0004]
[Problems to be solved by the invention]
However, conventional fishing lamps using incandescent bulbs or filament / halogen lamps have problems in terms of life and illuminance, and there is a danger that non-lighting may occur during operation and illuminance may be insufficient. Because of the low illumination of one of the lamps, it was necessary to attach many to the rod-shaped lamps, so that the frequency of replacement was high and a large number of new spare fishing lights had to be provided. In addition, in order to turn on a large number of conventional fish collecting lights, it was necessary to operate a large-capacity generator. Further, it is preferable that the fish collected from the Pacific saury is white light close to daytime sunlight, but the conventional incandescent lamps and filament / halogen lamps have a slightly yellowish emission color.
[0005]
On the other hand, the use of small discharge lamps such as metal halide lamps as fish-collecting lamps has been considered, but this kind of small discharge lamp takes time to relight after turning off the light, For example, since a high pulse voltage of about 20,000 volts is applied, there is a problem that a short circuit (short circuit) easily occurs in a base or a socket of a lamp.
[0006]
The present invention has been made in view of the above circumstances, and can repeatedly perform lighting and blinking in a short time, can obtain necessary illuminance with a small number of lamps, and can obtain white light suitable for fish collection. It is an object of the present invention to provide a fish-collecting light device that can achieve high luminous efficiency.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the power generated by the generator turns on the fish-collecting lamp constituting the discharge lamp via the ballast body side circuit and the instantaneous re-lighting circuit. The discharge lamp is a long arc type discharge tube in which a plurality of metals are sealed together with xenon gas inside a lamp body made of hard glass formed in an elongated cylindrical shape, A trigger wire constituting an electrostatic coupling is provided around the periphery along the longitudinal direction. By providing a trigger wire that forms an electrostatic coupling around the lamp body with a long arc type discharge tube, lighting and blinking can be repeated in a short time, and the illuminance required by a small number of lamps By filling a plurality of types of metals together with xenon gas, white light suitable for fish collection can be obtained, and the luminous efficiency can be increased.
[0008]
In the invention described in claim 2, the lamp body has an outer diameter of 12 to 20 mm and a light emission length of 250 to 350 mm, so that the light emission length can be lengthened and the required illuminance can be obtained with a small number. .

The high-voltage pulse generation circuit 27 is a circuit that generates a high-voltage pulse when the relay 26 is turned on and a power supply voltage is applied. The high-voltage pulse is applied to the input side of the high-frequency transformer 29 connected to the power supply line. Connected to be. The lamp voltage detection circuit 28 is a circuit that, when the relay 26 is turned on and the power supply voltage is applied, detects a voltage applied to the fish catching lamp 14 and detects a constant lighting voltage to turn on the switch. This switch is connected in series to the exciting coil of the relay 26. The instantaneous relighting circuit 13 is connected to a position close to the discharge lamp 30 in order to avoid the attenuation of the high-voltage pulse.
[0013]
In the discharge lamp 30, insulators 32, 32 are attached to both ends of a lamp body 31 made of hard glass formed in an elongated cylindrical shape, and arc terminals 34, 34 are arranged inside thereof so as to face each other. The connection terminals 33, 33 are attached to 34, 34, and the total length (A) between both insulators 32, 32 is formed to be, for example, 300 to 400 mm, preferably about 360 mm.

[0014]
In the fish-collecting light device 10 having the above-described configuration, a large number of the fish-collecting lights 14 equipped with the discharge lamps 30 are attached to a rod-shaped lighting device or the like provided on a fishing boat, and each of the fish-collecting lights 14 is connected to the output terminal of the instantaneous relighting circuit 13. To start lighting, first, the generator 11 is started and the breaker 21 is turned on. When the power supply voltage transformed by the transformer 22 of the ballast main body side circuit 12 is applied to the instantaneous relighting circuit 13, the timer circuit 25 Is activated, the relay 26 is turned on, and the high-voltage pulse generated from the high-voltage pulse generation circuit 27 is applied to the fish collecting lamp 14 via the high-frequency transformer 29 to start lighting. Simultaneously, when the relay 26 is turned on, the lamp voltage detection circuit 28 operates, detects the voltage applied to the fish collecting lamp 14, and turns off the relay 26 when the lighting voltage is detected. When the fish lamp 14 is not turned on, the relay 26 is turned off after 10 seconds set by the timer circuit 25, and the operations of the high voltage circuit generation circuit 27 and the lamp voltage detection circuit 28 are stopped. If an abnormality occurs in the fish collecting light 14 and the light is turned off, the off state of the relay 26 is maintained. The ballast body side circuit 12 constitutes a phase advance circuit, the phases of the input voltage waveform and the input current waveform match, and the input current at the time of starting is smaller than that during lighting, so that the efficiency of the generator 11 is improved It is not necessary to increase the capacity, and the difference between the ballast short-circuit current and the lamp current is small, so that the life of the fishing light 14 is prolonged. Further, the instantaneous re-lighting circuit 13 uses the timer circuit 25 and the lamp voltage detecting circuit 28 in combination to turn off the high-voltage pulse applied from the high-voltage pulse generating circuit 27 to the fish-collecting lamp 14. It is turned off and is not damaged by the failure of the timer circuit 25.
[0015]
Since the fish collecting lamp 14 is formed in a slender cylindrical shape and has a relatively long light emission length (B), the light emitting portion becomes larger and larger than that of a conventional filament lamp or a short arc type small discharge lamp. The required illuminance can be obtained with a small number of lamps. Further, since a plurality of types of metals are sealed together with xenon gas, white light close to sunlight suitable for fish collection can be obtained. Further, since the trigger wire 35 constituting the electrostatic coupling is provided on the outer peripheral portion along the longitudinal direction of the lamp main body 31, relighting is facilitated.
[0016]
In the above embodiment, the electric characteristics, shape, and the like of the discharge lamp 30 constituting the fish-collecting lamp 14 can be arbitrarily determined. However, it has been found that the one described in the embodiment can obtain preferable results.
[0017]
