BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub lighting device for illuminating the inside of a bathtub with bath water stored in the bathtub.

0002

2. Description of the Related Art Conventionally, there is a bathtub lighting device as shown in FIG. 2 for illuminating bath water in a bathtub 1. This bathtub lighting device is constructed so that a power supply section 9 provided close to the bathtub 1 is connected to an electric wire 11 from a lighting fixture 10 installed on the side wall 1a of the bathtub 1 with waterproof treatment. ing.

0003

By the way, when installing the lighting fixture 10 in the bathtub 1, the following electrical circuit is required by law for the lighting fixture 10. In other words, an insulated high voltage transformer 12 is provided in the middle of the wiring, and its primary side,
An overcurrent breaker 13 (breaker) is installed on the secondary side. Furthermore, the connection with the electric wire 11 from the secondary side is made using the plug connector 1.
4, and the electric wire 11 must be wired with a metal tube 15. Further, special type 3 grounding work 16 must be performed from the metal pipe 15 and the grounding electrode of the outlet, and first grounding work 18 must be performed from the contact prevention plate 17 of the insulated high voltage transformer 12. For this reason, in the conventional example as described above, the number of parts increases, and the construction to install the lighting fixture 10 in the bathtub 1 becomes large-scale, and there is a problem that it cannot be easily installed. there were.

[0004] The present invention aims to solve the above-mentioned problems, and it is possible to reduce the number of parts, reduce the amount of work required for construction, and safely install the system without making the installation work large-scale. The present invention aims to provide a bathtub lighting device that can provide

[0005]

[Means for Solving the Problems] In the present invention, in order to achieve the above object, a lighting device 3 is arranged in another room adjacent to the bathroom 2 so as to be located above the upper edge of the bathtub 1,
The through hole 4 provided in the side wall 1a of the bathtub 1 is closed with a transparent plate 5 provided inside the side wall 1a, and the optical fiber cable 6 led out from the lighting device 3 is connected to the through hole 4 provided in the side wall 1a. This is a bathtub lighting system that faces the inside of the bathtub.

[0006]

[Operation] The light from the lighting device 3 is irradiated into the bathtub 1 from the transparent plate 5 via the optical fiber cable 6, so that the interior of the bathtub 1 is illuminated.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on illustrated embodiments. The bathtub lighting device is composed of a lighting device 3 installed outside the bathroom 2 and an optical fiber cable 6 led out from the lighting device 3. The lighting device 3 is placed in another room adjacent to the bathroom 2.
is arranged at a higher position than the upper edge (flange portion) of the bathtub 1 in other rooms. The lighting device 3 is connected to a power source in another room by direct connection to indoor wiring or by a plug-in connector, and grounding work for the lighting device 3 is not required by law. A through hole 4 is provided in the side wall 1a of the bathtub 1.
The through hole 4 is closed by a transparent plate 5 arranged inside the side wall 1a. Here, the transparent plate 5 is arranged inside the side wall 1a while ensuring watertightness, so that bath water in the bathtub 1 does not enter into the through hole 4. An optical fiber cable 6 is led out from the lighting device 3, and the tip of the optical fiber cable 6 passes through the bathroom wall 7 and is disposed in the through hole 4 provided in the side wall 1a.

[0008] Thus, the light from the lighting device 3 is irradiated into the bathtub 1 via the optical fiber cable 6 and the transparent plate 5.
Bath water in the bathtub 1 is illuminated by light from the lighting device 3. Here, when light is irradiated into the bath water in the bathtub 1, which is called a milky bath, and which generates micro bubbles in the bath water, the irradiated light becomes diffused by the micro bubbles, resulting in a lighting effect. It will improve.

Since the bathtub lighting device is constructed as described above, that is, the bathtub lighting device is composed of the lighting device 3, the optical fiber cable 6, and the transparent plate 5 as the lowest members. This means that there is no need to attach or install additional parts due to legal regulations, and the bathtub lighting system can be configured with a reduced number of parts, and the construction period can be shortened. It can be easily installed. Furthermore, since the lighting device 3 is placed at a higher position than the upper edge of the bathtub 1 in other rooms, even if bath water is transmitted through the optical fiber cable 6, the base end of the optical fiber cable 6 will not pass through. Since it is arranged at a higher position than the hole 4, bath water does not enter into the lighting device 3.

Effects of the Invention As described above, in the bathtub lighting device of the present invention, the lighting device is arranged in another room adjacent to the bathtub so as to be located above the upper edge of the bathtub, and is installed on the side wall of the bathtub. The through hole is closed with a transparent plate provided inside the side wall.
The optical fiber cable led out from the lighting device is exposed to the through hole provided in the side wall, so when installing the device, there is no legal restriction as in the past, and it is easy to install. It is possible to reduce the number of parts and labor required for construction, and does not require large-scale installation work, unlike conventional It can be installed in a state where electrical safety is ensured without an isolation transformer or grounding work. Furthermore, the lighting device is placed above the upper edge of the bathtub in other rooms so that it will not be submerged in bath water.
