Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing lighting device comprising a metal vapor discharge lamp.

Traditionally, lighting equipment for fishing has consisted of an old-fashioned incandescent light bulb combined with a simple reflective shade, but in recent years, improvements have been made to lighting equipment for fishing in order to improve fishing efficiency. Ta.

As light sources, halogen incandescent bulbs have replaced the old incandescent bulbs, and mercury-thallium mixed metal vapor discharge lamps, which emit a large amount of green light, have come into use as discharge lamps, and the amount of fishing has decreased. As the number of lights has increased significantly, it has also become clear that the design of lighting equipment for fishing needs to be significantly changed.

The object of the present invention is a fishing lighting device equipped with a metal vapor discharge lamp, but as is well known, a metal vapor discharge lamp requires a power supply stabilizing device (commonly known as a ballast). However, it is inconvenient to use it by attaching it to the rope or top of the mast of a fishing boat.Furthermore, as we discovered during the research process for this invention, it takes a long time for the luminous intensity of metal vapor discharge lamps to stabilize. It was found that the stabilization time needed to be shortened, as the unstable ultraviolet light emitted during this time had a negative impact on fishing.

The purpose of the present invention is to provide a new lighting device that is a radical improvement of fishing lighting devices equipped with metal vapor discharge lamps from the above various viewpoints, and is characterized by the following: a starter box disposed above the reflector, a spacer separating the reflector and the starter box by a certain distance, a metal vapor discharge lamp disposed below the reflector, and adjacent to the metal vapor discharge lamp. A resistor consisting of a metal coil placed in a protective tube, a socket fixed to the reflector and receiving both ends of the metal vapor discharge lamp and the resistor, and fixed to the reflector or the starter box. and a starter circuit disposed within the starter box, and the metal vapor discharge lamp and a resistor are electrically connected in series.

The present invention will be described below with reference to embodiments and the drawings.

Figure 1 is an explanatory diagram of disassembly and assembly of the example lighting fixture;
Although the figure is also a front view, a substantially U-shaped arm 1 fixed to a predetermined member such as a mast of a ship is fixed to a rectangular parallelepiped-shaped starter box 2 so as to embrace it. The reflector 4 is a cylindrical spacer 3
The reflecting plate 4 and the starter box 2 are fixed to the lower part of the starter box 2 via the spacer 3, and the reflector 4 and the starter box 2 are spaced apart by the height of the Spencer 3. A pair of sockets 5 are fixed to the lower surface of both ends of the reflecting plate 4, and each socket 5 is formed with a holding hole into which the ends of two resistors 6 are inserted. The resistor 6 is made by inserting a resistance wire such as a nichrome wire or a kanthal wire into a protective tube such as an opaque quartz tube, and its both ends are fixed in the holding hole of the socket 5 with an adhesive or the like. be done. These two resistors 6 are connected in series within the socket 5, and a cable 9 connected to both ends of the series resistors 6, 6 communicates with the starter box 2.

A metal socket 7 for receiving both ends of the metal vapor discharge lamp 8 is connected below the socket 5, and the cable 10 for the metal vapor discharge lamp 8 held by this socket 7 is also connected to the starter box. It is connected to 2.

Note that the vibration isolation mechanism using springs inserted between the reflector 4 and the socket 5, and between the socket 5 and the socket 7 is omitted, but this vibration isolation mechanism allows the resistor 6 and the metal vapor discharge lamp to 8 etc. are protected from ship vibrations and shocks. Further, the area below the reflector plate 4 is covered with a transparent guard box (not shown) to prevent it from being exposed to seawater or the like.

Next, an example of an electric circuit will be described in FIG. 3. The metal vapor discharge lamp 8 and the resistor 6 are connected in series as shown in the figure, and the starter transformer 12 includes a bypass capacitor C ₁ , a delay switch 13, It is protected by a thermal switch 14. The delay switch 13 is an oil pot type in which the metal that operates the contact is immersed in oil, and the electromagnetic coil
Even if current flows through _R1 , the metal that operates the contact is immersed in oil, so it cannot move at high speed, and the normally closed delay switch 13 is configured to open two seconds after the electromagnetic coil _R1 is energized. ing. The thermal switch 14 is also a kind of delay switch, but 10
When the current is applied for more than a second, a bimetal (not shown) is activated by the heat generated by the resistor R, and the electromagnetic coil _R2 is energized to open the normally closed thermal switch 14.

When the breaker 16 is turned on and a start operation is performed, a current flows through the starter circuit of the power supply α→delay switch 13→thermal switch ₁₄ →primary winding T1 of the starter transformer 12→power supply β. When high voltage is generated across the secondary winding T ₂ of the transformer 12, the capacitor C ₃ is charged, and when this voltage reaches the withstand voltage of the spark gap SG, SG is discharged. High voltage, high frequency electricity is applied to _T3 . Therefore, even higher voltage and high frequency electricity is generated in the secondary winding T ₄ of the Tesla coil 15,
The metal vapor discharge lamp 8 is turned on. When this lights up, power supply α → resistor 6 → resistor 6 → Tesla coil 15
Current flows through the circuit of secondary winding T ₄ → metal vapor discharge lamp 8 → power supply β, and lighting is maintained.

At this time, as described above, the delay switch 13 is opened two seconds after the breaker 16 is closed, so no current flows through the transformer 12 from then on, so that the transformer 12 is protected. If, due to some abnormality, the breaker 16 does not turn on once it is closed, this closing operation must be repeated several times. Therefore, the time that the delay switch 13 is closed becomes longer, and the temperature of the transformer 12 increases, but the thermal switch 14 opens after 10 seconds, so no current flows through the transformer 12 from then on, so that the transformer 12 is protected. be done.

As described above, the transformer 12 is connected to the switch 13,
Protected by 14.

Since the present invention is as described above, it has the following technical effects.

(a) Since a resistor is used instead of a ballast, the resistor is extremely small and lightweight, and therefore the entire lighting device is also extremely small and lightweight. Furthermore, since the lash current is large, the light amount stabilization time can be shortened. For example, thallium iodide and mercury are sealed in a quartz bulb with an inner diameter of 28 mm, the distance between the electrodes is 11 cm, and a metal vapor discharge lamp with a power supply voltage of 240 V, a rated lamp current of 18 A, and a rated lamp voltage of 170 V is lit. , when using a ballast using a conventional chiyoke coil, the weight of the ballast itself is reduced.
50Kg, lash current 28A, stabilization time 3 minutes, but in this invention, using a Kanthal wire for the resistor and designing the whole to 4 ohms, the weight of the resistor is less than 1Kg, the lash current 52A, and the stabilization time is 3 minutes. The time is 20 seconds.

(b) Therefore, the negative effects of unstable ultraviolet rays can be prevented, and the heat generated by the resistor due to the large current flowing in the early stages of lighting, which originally has a negative impact on the electrical circuit, can be prevented from occurring in front of the reflector. , arranged in parallel with the metal vapor discharge lamp 8,
The metal vapor discharge lamp 8 is effectively used to heat it, and the space formed between the starter box 2 and the reflector 4 prevents any heat from being transmitted to the electric circuit inside the starter box. Therefore, it has the advantage of eliminating any heat shielding means for electrical circuit components.

(c) Since the resistance wire that makes up the resistor is housed in a protective tube, it is less likely to be damaged by sea breeze, and the lighting equipment is safe to handle.

As described above, the present invention has the advantage of being able to provide a fishing lighting device equipped with a metal vapor discharge lamp that is small, lightweight, convenient to use, and free from the adverse effects of unstable ultraviolet rays during the initial stage of lighting. be.
