Abstract

PROBLEM TO BE SOLVED: To increase a decorative effect, reduce heat generation, promote the growth of corals and water plants, and extend their lives by arranging high-intensity parallel light LED lamps having different luminescent colors for each block on a substrate provided on the water tank. SOLUTION: High-intensity parallel light reflection type LED lamps of red, green and blue, for example, are arranged in turn for each line or in turn in each line on the substrate of a radiation device 4 arranged on a water tank 1. The controller 7 of the radiation device 4 is provided with a switch 8 and a dimming volume 9, and living beings and molded objects 10 colored in red, green and blue are arranged in the water tank 1. When only the lamp of blue color is lighted, for example, the light environment of 450-550nm in the sea is reproduced. When the lamps are lighted at the ratio of the blue color of 20%, green color of 30%, and red color of 40%, the light quality balance near a light synthetic action curve is obtained, and the growth of water plants and corals is promoted. The life of the LED lamp is five times the life of the general fluorescent lamp or longer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lighting device for an aquarium.

[0002]

2. Description of the Related Art Hitherto, various structures have been implemented as a lighting device for an aquarium for storing appreciation fish, coral, aquatic plants, and the like. For example, in general, an oxygen supply device for supplying oxygen to the inside of the water tank is provided at the top of the water tank, a filter is provided at an appropriate position in the water tank, and a fluorescent lighting device is arranged at the top of the water tank.

[0003]

However, according to the lighting device for aquarium described above, the light of the fluorescent lamp is projected into the aquarium, but the decorative effect is small and the coral and the coral in the aquarium are increased to increase the water temperature. The growth promotion of plants such as aquatic plants is small,
There is a disadvantage that the life is short.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides an illuminating device for an aquarium which has a large decorative effect, promotes the growth of corals and aquatic plants in the aquarium, and generates less heat. Aim.

[0005]

The present invention according to claim 1 relates to an illuminating device for an aquarium in which an irradiating device is provided on an upper portion of an aquarium, and a decoration is arranged inside the aquarium. Further, on the upper part of the water tank, there is provided a substrate on which high-brightness parallel light LED lamps of different emission colors are arranged for each block. Then select the LED lamp as appropriate and turn it on.
The parallel light from the lamp is applied to the decoration inside the aquarium to promote the effects in the aquarium and the growth of living creatures.

According to a second aspect of the present invention, the decorative object of a plurality of colors is a shaped object or a plant, and the shaped object has red, green, and blue, and the parallel light from the LED lamp is supplied to the inside of the water tank. Irradiation is performed on the decoration to promote the production in the aquarium and the growth of coral and aquatic plants.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes an aquarium having a length of, for example, about 30 cm, a width of about 60 cm, and a height of about 40 cm, and is arranged at a store entrance, a hotel lobby, or the like. Reference numeral 2 denotes a filter device arranged on the upper portion of the water tank 1, which contains a filtering material therein. Reference numeral 3 denotes an air pump configured in combination with a filter device.

In FIG. 1 to FIG. 3, reference numeral 4 denotes an irradiation device arranged above a water tank, which is constructed using a high-brightness parallel light reflection type LED lamp. Reference numeral 5 denotes a substrate for supporting the LED lamps, and reference numeral 6 denotes LED lamps arranged in each row, which are configured using, for example, red, green, and blue LED lamps. For example, red, green, and blue LED lamps are alternately arranged for each row on a single substrate. Further, red, green and blue LED lamps may be arranged alternately in each row. FIG. 3 shows an irradiation device installed in parallel with the filter device, and an LED.
The lamps are configured in a 49 × 7 arrangement. Reference numeral 7 denotes a control unit of the irradiation device, 8 denotes a switch, and 9 denotes a light control volume. The irradiation time is set by a 24-hour timer.

Reference numeral 10 denotes a model placed inside the water tank, which is made of, for example, acrylic resin or methacrylic resin. Examples of the shaped object include fish and aquatic plants. Further, the modeled object is configured to be colored red, green, blue, or the like. In addition, creatures such as aquatic plants and corals other than fish are arranged as decorations inside the aquarium.

The above-described lighting device for an aquarium has the following operation. For example, when only the above-mentioned blue light LED lamp is turned on, an undersea light environment of 450 nm to 550 nm can be reproduced. When the LED lamp is turned on at a ratio of 20% of blue light, 30% of green light, and 40% of red light, the light quality balance approximates the photosynthesis action curve, and the growth of aquatic plants, corals and the like can be promoted. In addition, various colors can be obtained by changing the ratio of green light, blue light and red light of the LED lamp according to the color of fish, molded objects and creatures stored in the aquarium, depending on the application The production can be emphasized. When a fluorescent lamp generally used in the past is used as the irradiation device for the aquarium, the life is about 10,000 hours. However, the LED lamp has a life of 50,000 hours or more and is five times longer. It is life.

[0011]

Since the present invention is constructed as described above, the decorative effect of the aquarium is great, the growth of living things in the aquarium is promoted, and there is a special effect that the life is long.
