DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of breeding and breeding small animals and plants such as ornamental creatures and farmed creatures.

[0002]

2. Description of the Related Art Some conventional animal rearing cases have a hot cathode fluorescent tube.

[0003] Further, there is an incandescent lamp, a halogen bulb, a mercury lamp and the like.

[0004] There is no living breeding case in which a fluorescent lamp device with a light control device is arranged.

[0005] There is no commercial power supply, a breeding case, or a light emitting unit disposed in a circulatory system thereof and an auxiliary circuit thereof are insulated.

[0006]

At present, the hot cathode fluorescent tube device provided in the ornamental fish breeding case is so large that it is arranged on the upper surface of the water tank, and there is a problem in the maintainability of the water tank.

Further, there is a risk of electric leakage or electric shock when the light emitting device disposed due to insulation problems falls into the water in the breeding case.

When an incandescent lamp or a halogen bulb is used, the power consumption is large, the illuminance corresponding to the power consumption is insufficient, and the temperature inside the case increases due to heat generation.

In the conventional light emitting device, since the size of the device is large, there have been problems in appearance deterioration and space utilization.

[0010] The so-called underwater fluorescent lamp provided in an ornamental fish breeding case cannot be arranged in a small living breeding case because of its large size.
The resulting electric shock and destruction of the device were problems.

In a conventional breeding case, the illuminance is not controlled in a 24-hour cycle or in the nature of spring, summer, autumn and winter.

[0012]

The purpose of the present invention is to provide a living breeding case according to the present invention in view of the problems of the prior art, which enhances the maintainability of the living breeding case, and if the lighting device disposed in the case has any cause. The purpose of the present invention is to produce a light that is safe and has a good appearance without electric shock even if it falls into the water or breaks down in the water, and that matches the natural cycle.

[0013]

In order to achieve the above-mentioned object, in the breeding case according to the present invention, the cold cathode fluorescent tube is housed in a safe insulated outer case, and the cold cathode fluorescent tube is stored in the breeding case and its circulatory system. It succeeded by isolating the circuit and the commercial power supply and supplying low voltage power. In addition, by providing a dimming circuit, the illuminance was successfully adjusted in a natural cycle.

[0014]

With the above configuration, it is possible to provide a biological breeding case which can reduce the size of the lighting portion of the biological breeding case and safely arrange it, and can produce a change in illuminance close to a natural environment with high maintenance and good appearance. It has become possible.

According to FIG. 9A, the lighting fixture can be fixed to the living-body breeding case wall surface 11 with the sucker-like fixing portion 21. In addition, it is possible to arrange a reflector g for the purpose of producing a brighter interior of the breeding case and preventing light from leaking to the outside.

According to FIG. 9B, the lighting fixture fixing portion 22 is detachably attached to the fixed bar 12 arranged on the upper surface of the water tank.
It is fixed by the fastener 30 via the second. The fastener 30 is a screw-like one, a fitting-like one,
Any type of clip or the like can be used as long as it can be fixed according to the purpose.

According to this figure, it is shown that one or more cold cathode fluorescent tubes a are arranged and that the shape of the outer case d may be any shape.

The reflecting plate g is made of metal or resin, or has a fluorescent tube body provided with these functions.
In the case where the protective case has the function and the case where the power supply circuit shown in FIG. 3 is provided, a partition which can be a reflection plate can be arranged between the circuit b and the fluorescent tube a. It is shown that any arrangement can be used as long as the arrangement takes into account the reflection and the leakage of light to the outside.

As described above, if it is possible to use the cold-cathode fluorescent tube to produce a bright interior of the breeding case, it is not shown in the drawing, but can be incorporated into the lid or device on the top of the breeding case, Indicates that any form, such as incorporating inside or outside the breeding case, can be placed anywhere.

Also, by arbitrarily setting the filling and the luminous body inside the cold cathode fluorescent tube. Fluorescent tubes of various wavelengths can be provided.

In the conventional ornamental fish lighting, a hot-cathode fluorescent tube having a tube diameter of 22.5 mm, a length of 330 mm, and a power consumption of 10 W is used for a water tank having the size shown in FIG. , Length 360mm, depth 100mm,
It becomes large with a height of about 60 mm.

When the cold cathode fluorescent tube device of the present invention is used, the above-described two devices corresponding to 4 W are temporarily enclosed in a transparent insulating protective case, and a device provided with a power supply circuit inside as shown in FIG. Similarly, even if it is provided on the top of the water tank,
mm, depth 40mm, height 40mm and volume
/3.75 times. When all the power supply circuits are arranged outside as shown in FIG. 4 and only the fluorescent tube and the insulating protective case are arranged in the water tank as shown in FIG. 1, the device to be arranged is 300 mm in length, Depth 10mm, height 10
The volume can be reduced to about 1/72 times as much as the volume, and about 1/35 times as much as the weight.

Here, length 300 mm, depth 180 m
m, there is a plastic breeding case with a height of 180 mm. Lamp power consumption of 4 W similar to FIG.
A thing provided with a reflection plate as shown in FIG.
An illuminometer was placed on the bottom surface at the center of the case to block the influence of external light, and the illuminance was measured. The result was 980 LUX for one cold cathode fluorescent tube and 1812 LUX for two tubes. Similarly, when a commercially available slide light 360 (supplied with a hot cathode fluorescent tube 10W manufactured by Nissau Co.) was similarly installed and the illuminance was measured, it was 1568 LUX. In this fluorescent light device,
The fluorescent tube was not protected by acrylic or glass, and the light of the fluorescent tube was directly radiated into the case. Also,
The same measurement was performed with a 6 W fluorescent lamp device (protected by an acrylic case) attached to a commercially available hot cathode fluorescent tube, and the result was 480 LUX.

If a tube having a tube diameter of about 4 mm or 6 mm is used, one cold cathode fluorescent tube can be used and a commercial product for ornamental fish, 10 W
Illuminance similar to or higher than that of the fluorescent lamp device can be obtained. This is a device smaller than the conventional hot-cathode fluorescent tube 10W alone. Of course, the volume can be further reduced by making the insulating protective case circular, flat, or elliptical.

FIG. 10 shows an embodiment using an ultraviolet ray generating cold cathode fluorescent tube a3. This device is used for growing aquatic organisms, and has a casing h using ultraviolet-resistant resin.
It is a mechanism that circulates water inside the interior. Ultraviolet ray generating cold cathode fluorescent tube a3 is made of quartz glass
1, which is insulated and protected. Reference numeral h1 denotes a water supply / drain port, which is designed to supply water from one of the left and right sides and drain the water in the opposite direction.

Although the conventional apparatus employs a hot cathode fluorescent tube, the apparatus is large and has a problem of space. However, according to the present invention, the apparatus can be mounted in a small aquarium, and a biological breeding case and its circulatory organ are provided. The diameter of the device part arranged in the system is 30 mm
Something is possible.

This means that the amount of expensive quartz glass or UV-resistant resin used can be reduced, and the cost can be greatly reduced.

In addition, a straight tube or another shape of an ultraviolet ray generating cold cathode fluorescent tube can be arranged in accordance with the specifications shown in FIG. 5, and even if the device is destroyed by providing an insulating transformer outside, electric leakage or electric shock (commercial power supply) may occur. Danger of insulation from the ground) is also avoided. In addition, when a lamp or the like is destroyed and the inverter circuit is in a no-load state, a high voltage is generated. Therefore, it is possible to incorporate a safety device capable of detecting the state and stopping oscillation from the inverter circuit. .

In the present invention, a dimming function can be added to the power supply circuit, unlike the conventional hot-cathode fluorescent tube device arranged in a living breeding case.

With conventional hot cathode fluorescent tubes, dimming is not easy except for special ones. This means that an arbitrary brightness can be set manually or mechanically or by using a timer together with the volume in a living breeding case in which the same cold cathode fluorescent tubes are arranged.

FIG. 11 is a simplified diagram of one embodiment of the dimming circuit. Dimming can be performed by providing a duty generation circuit w and turning on and off the inverter circuit b1 at a frequency of about 100 Hz. The power receiving terminal u2 can receive power such as AC or DC depending on the circuit design. In addition, the duty generation circuit w has a 365
A day timer can be provided to perform the duty control or the power supply stop for each time to enable dimming according to the purpose. In addition, illuminance management in consideration of the latitude of the country of origin of the breeding organism and weather conditions can also be performed by the power supply circuit provided with the storage circuit.

When breeding an organism, the organism has a rhythm to light. In a conventional fluorescent tube arranged in a breeding case, it is forced to select whether it has a certain amount of output or not. In the present invention, by adding a timer and a luminous flux adjusting device to the power supply circuit, when turned on, the luminous flux is set to be low, the luminous flux is raised like a sunrise in the natural world, and the highest output power is supplied when the value is at noon in the natural world, It is possible to control such that the output gradually decreases as the day inclines, and the power supply is stopped at the time of sunset. These rhythms differ depending on the breeding organism, but the power supply circuit can control the spring, summer, autumn and winter illuminance according to the organism throughout the year. It is also possible to assume a rainy day or a cloudy day.

When breeding an organism that is sensitive to moonlight, it is possible to provide lighting that can be used as moonlight at night according to the natural cycle.

For example, using one cold cathode fluorescent tube,
Illuminance management that can be performed during the day is performed by a power supply circuit, and the illuminance is gradually decreased, and power supply is stopped about 30 minutes after a normal sunset time. However, at that time, in the natural world, if the power supply is stopped for a half month, the power supply corresponding to the power supply may be performed without stopping, and the illuminance that may be a half month may be maintained. Then, at midnight, at the time when the half moon disappears from the horizon, it should be turned off. In addition, if the moon is a full moon, power supply may be performed so that the illuminance is the full moon after sunset. These can be controlled by the power supply circuit for 24 hours or throughout the year.

When breeding organisms that tend to be sensitive to wavelength, one or more cold cathode fluorescent tubes are used for daylighting and another fluorescent tube is used for moonlighting. It is also possible to incorporate the LED or the surface light emitter into the living breeding case arrangement lighting unit x of the present invention.

FIG. 12 is a diagram showing one embodiment of a simple circuit according to the present invention in which LEDs are arranged. A timer or the like is provided in the duty generation circuit to adjust the time and illuminance, and the LED 50 and the LED 5 are connected via the switching transistor m5.
1 is configured to supply power. At this time, the number of LEDs can be any number as long as it is one or more. In addition, power can be supplied in combination with a cold cathode fluorescent tube, or can be supplied independently to an LED.

FIG. 13 is a diagram showing one embodiment of a simple circuit diagram according to the present invention provided with a surface light emitter. As in FIG. 12, the structure is such that power is supplied from the duty generation circuit to the surface light emitter 60 via the inverter circuit b2.

These weak light source power supply circuits can be arranged in the breeding case arrangement illumination unit x and the external arrangement power supply circuit y. Also, the illuminance can be adjusted by the power supply circuit for 24 hours a year, similarly to the cold cathode fluorescent tubes.

When growing underwater organisms, it is necessary to take into account the scattering and absorption of light in the water, which changes the spectral characteristics and illuminance under the water.

These can be controlled by one or more circuits by using one or more fluorescent tubes or weak light sources by using one or more fluorescent tubes or weak light sources with reference to the spectral characteristics, color temperature, and illuminance of the natural world.

[0054]

As described above, a cold-cathode fluorescent tube and a weak light source are used in a breeding case to provide a safe and highly maintainable living breeding case for breeding creatures.
