Patent Publication No. 2002-4252

The present invention is not limited to lighting in the bathroom, but is a compact and underwater lighting that can be provided as a lighting effect for an event or church wedding, a reception for a wedding reception, or a shining toy by giving shine to almost the entire surface of the lighting device. The purpose is to provide.

The underwater lighting device according to the present invention comprises a transparent or translucent hollow container provided with a large number of irregularities on at least an inner wall surface of a wall surface or an inner wall surface, or a hollow container provided with a large number of holes on the surface of the hollow container. In the case of a hollow container without a hole, the container floats on the water surface, and when a hole is made in the wall of the container, the container sinks. In any case, since the heavy light emitting device is fitted to the lower part of the hollow container, the energizing terminal or switch is in contact with water.

The overall shape of the hollow container includes characters and animals, and the shape and color are not limited.
In addition, a light-emitting device including a light-transmitting sealed case that houses a light-emitting element, a battery, and a circuit has a waterproof structure.

If the bottom of the sealed case of the light emitting device is flattened, a stable set is possible. Light emitting elements include krypton spheres, halogen spheres, and light bulbs, but light emitting diodes with low power consumption are optimal. The light emitted from the light emitting element hits the transparent irregularities on the inner wall of the hollow container and is irregularly reflected, and part of the light is directly emitted from the hole and the whole container is shining.

Alternatively, the light emitted from the light emitting element is first diffused by the light diffuser in the sealed case or the light diffusing portion of the case wall, and further, the light strikes the transparent irregularities on the inner wall of the hollow container and the entire container has a shine. Such a double diffusion structure is effective for LEDs having directional characteristics.
Further, the production and decoration effects are improved by adopting a configuration in which a plurality of light emitting elements are arranged, a configuration in which the circuit is a flashing circuit, a configuration in which the LED is flashing, and a configuration in which the light emission color changes with time.
By making the bottom of the sealed case openable and closable so that the battery can be replaced, it can be used repeatedly.

The underwater lighting tool of the present invention may be floated on the water surface or submerged in water, or the lower part of the lighting tool may be used by immersing it in water, and is not limited to underwater words.

When it is put into water, light emission starts automatically, and the light emitted from the light-emitting element is diffusely reflected by the irregularities on the inner wall surface, and the entire surface of the container shines. It is possible to provide an underwater illuminator having a production effect and a decoration effect. In addition, the underwater lighting device of the present invention can be enjoyed by itself, but if it is floated on the surface of a large number of water tanks, bathtubs, pools, etc., and each has a different light emission color, it is possible to enjoy beautiful effects.

Hereinafter, the form of the first embodiment of the underwater illumination tool of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the skin layer of the hollow container 2 is made of a wall made of a small lump such as a sphere or a pellet, and a required portion of the wall has a hole 10 generated between the spherical or pellet lumps, The outer surface is smooth, and the inner surface is uneven, with a number of protrusions of spherical or pellet-like lumps protruding.

The wall of such a shape is such that the surface of the small block melts and adheres to each other while the small block of ethylene vinyl acetate copolymer resin pellets is put into a spherical mold and heat-molded while giving a rotational motion. Connect together. The outer surface is melted and softened and becomes smooth. By this method, a spherical hollow container 2 having a diameter of 65 mm is formed. A hole having a diameter of 33 mm is provided in the lower portion of the hollow container 2, and a dome-shaped sealed transparent case 6 having a flat bottom having a diameter of 33 mm and a height of 38 mm is inserted into the hole so that the bottom portion is exposed and fixed.

The inside of the transparent case 7 is divided into two upper and lower chambers, and the lower chamber contains a circuit 5 for flowing a current of 10 mmA to 20 mmA, an LED, and a battery. Two energizing terminals exposed to the outside are connected to the circuit 5 at the bottom of the transparent case 6, and a weak current flows between the terminals in contact with water, the circuit 5 enters, and the rated current flows and lights. To do. The lit light is reflected and diffused by hitting an indeterminate transparent lump or a transparent lump containing bubbles contained in the upper chamber of the transparent case 6. The diffused light hits the unevenness of the inner wall of the hollow container 2 from the transparent case 6, and is further diffused and emitted from the entire container. Further, light is emitted from the through-hole 10 to shine as a whole.

The form of 2nd Example of the underwater lighting fixture of invention is demonstrated referring drawings.

The locking frame 12 is fitted into the lower opening of the hollow container 2. The light emitting device 7 is detachably attached to the locking frame 12 (FIG. 3). The light emitting device 7 is covered with a sealed case 6 as in the first embodiment, and the light at the tip of the light emitting device 7 strikes the irregularities on the inner wall of the hollow container 2 from the case 6 and is diffused and emitted from the entire container. Therefore, in this embodiment, the light diffuser 11 is not necessarily required. In addition, there exists the following advantages by setting it as the structure which attaches | detaches the light-emitting device 7 detachably like a present Example. When the battery runs out, it can be used repeatedly by replacing it with a new light emitting device 7. If a defective light emitting device 7 is found during mass production, the light emitting device may be replaced. Only the light emitting device 7 that has passed the water resistance test in advance can be used.

Therefore, as shown in FIG. 2 and FIG. 4, when a little water is put into a glass or white container and the lighting device of the present invention is placed therein, the light is emitted as described above. Many can be arranged to create expressions. Needless to say, it will be taken out after use and turned off if water is blown.
