Description

[Detailed Description of the Invention] The present invention relates to the improvement of a battery-powered underwater lamp for attracting fish, and more specifically, the invention mainly uses a combination of a discharge tube that emits ultraviolet rays intermittently and a translucent material equipped with a phosphorescent pigment to alternate between light and dark. This invention relates to an underwater light for attracting fish that emits light continuously.

Some fish, such as squid, have so-called "phototaxis" which allows them to approach a light source when stimulated by light.

Therefore, fishing lights called urabi were lit to illuminate the sea surface.
Although such phototaxis is used to gather and capture fish, it has the disadvantage that the fish are distributed widely due to light scattering.

In order to solve these problems, battery-powered underwater lamps have been used in which the light source is housed in a small waterproof capsule and the tip of the capsule is illuminated.

By the way, it is known that the highest value of the visual sensitivity curve of fish is in blue-green light with a wavelength of approximately 510 mm, and a fluorescent discharge tube that emits blue-green light with a wavelength of around 510 mm is usually used as a light emitting source.

Specifically, for example, a pronking oscillation circuit is connected to a battery, a series circuit of a stabilizing resistor and a fluorescent discharge tube is connected to the output winding of the transformer, a pulse is generated by the bronking oscillation circuit, and a pulse is generated by the transformer. The pressure was raised to continuously light the fluorescent discharge tube.

As is well known, animals tend to pay more attention to objects that are moving than to objects that are stationary.

The same is true for fish, and it is thought that they are more easily stimulated by a light whose brightness changes repeatedly than by a light that is turned on continuously.

Therefore, the purpose of this invention is to be able to change the brightness periodically with an extremely simple device configuration, thereby further improving
To provide an underwater light for attracting fish that can enhance the effect of attracting fish.

Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is an explanatory diagram showing an embodiment of the present invention.

A discharge tube 1 that mainly emits ultraviolet light, a blinking circuit 2 for the discharge tube 1, and a battery 3 serving as a power source are housed in a waterproof capsule 4.

The waterproof capsule 4 has a two-part structure so that the battery 3 can be easily replaced, and the capsule main body 5 and the light-transmitting camp 6 are screwed together via a packing I, so as to be in a liquid-tight state.

The inner surface of the light-transmitting camp 6 is coated with a luminescent pigment 8.

Luminous pigments have the property of absorbing and accumulating light from the sun, electric lights, fluorescent lamps, and ultraviolet lamps, and then gradually releasing and emitting the accumulated light after the light stops arriving. The cycle of one light emission can be repeated any number of times.

For example, there is a zinc sulfide based pigment (ZnS-Cu) as a storage pigment that emits light around 510 rran, which is preferred by fish, and it is preferable to use such a phosphorescent pigment.

Since the shorter the wavelength of the stimulating light beam is, the more effective it is for luminescence, the discharge tube 1 is preferably filled with an inert gas or a mixture thereof that mainly emits ultraviolet rays.

The blinking circuit 2 is connected between both terminals of the battery 3 by a spring 9 housed in the capsule body 5 and a lead plate 10, and causes the discharge tube 1 to blink at a preset period.

An example of the blinking circuit 2 is shown in FIG.

A blocking oscillation circuit 12 is connected to the battery 3, and a discharge tube 1 and a capacitor 1 are connected to the output winding 13a of the transformer 13.
4, a rectifying diode 15, and a stabilizing resistor 16 are connected in series.

The output voltage of the battery 3 is boosted to a voltage at which the discharge tube 1 can be discharged by the operation of the fronting oscillation circuit 12 and the transformer 13, and the obtained high-voltage pulse output is half-wave rectified by the rectifying diode 15, and then by the stabilizing resistor 16. The capacitor 14 is charged via the capacitor 14.

Since the charging current of the capacitor 14 is limited by the stabilizing resistor 16, the terminal voltage of the capacitor 14 gradually increases.
When the discharge starting voltage of the discharge tube 1 is reached, the discharge tube 1 discharges.

Then, the voltage of the capacitor 17 suddenly drops, and the discharge tube 1 is no longer able to maintain the discharged state, and the discharge stops.

Since the pronking oscillation circuit 12 operates continuously, after the discharging stops, the capacitor 17 starts charging again.
Since this charging and discharging process is repeated thereafter, the discharge tube 1 blinks.

The cycle of this blinking is approximately determined by the time constant of the stabilizing resistor 16 and capacitor 14, so by selecting the resistance value or capacitance value appropriately, you can set any blinking state from a blinking state close to continuous lighting to a faulty light with a long cycle. can do.

It goes without saying that the rectifying diode 15, the stabilizing resistor 16, and the discharge tube 1 can be connected in any order.

When ultraviolet light is emitted from the discharge tube 1, the phosphorescent pigment 8 applied to the inner surface of the transparent camp 6 is stimulated to emit light.

When the discharge v1 stops, the phosphorescent pigment 8 gradually releases the accumulated light, and the phosphorescent luminescence continues until the discharge tube 1 discharges next.

Since this process is repeated thereafter, Camp 6 does not flicker on and off, but periodically repeats light and dark, making it look like an animal and stimulating the fish.

- Luminous intensity when the underwater lamp according to the present invention is in operation
fIl is shown in FIG.

The time TI is the luminous state when ultraviolet rays are being emitted from the discharge tube 1, and the time T2 is the phosphorescent luminescent state when the discharge of the discharge tube 1 is stopped, and the light becomes brighter as time passes. You can see how the value changes periodically.

In the above embodiment, the phosphorescent pigment is applied to the inner surface of the translucent camp 6, but the phosphorescent pigment may be mixed and molded at the time of molding the translucent camp, or a phosphorescent pigment may be applied between the discharge tube and the translucent camp. Alternatively, a luminescent pigment may be coated or mixed on the glass of the discharge tube.

In short, any structure is sufficient as long as the ultraviolet rays emitted by the discharge are irradiated onto the phosphorescent pigment and the resulting light is emitted to the outside of the waterproof capsule 4.

As described above, the present invention is an underwater light for attracting fish that combines a discharge tube that mainly emits ultraviolet rays, its blinking circuit, and a transparent material having a luminescent pigment placed around the discharge tube, so it has an extremely simple device configuration. Despite this, continuous and periodic changes in brightness can be obtained, making it look like an animal, and it can provide stronger stimulation to fish than just continuous lighting, so it is extremely effective at attracting fish. 5 things fish like
If a luminescent pigment having an emission wavelength of around 10 rrrm is used, the fish-attracting effect can be further improved, and the practical effect is very large.
