れる。``Conventional technology'' Conventionally, when growing plants in cultivation conditions where sunlight is insufficient or impossible, portable potted plants are usually moved to a window to receive sunlight, and other The current situation is that there is no suitable method for this, and it is considered difficult. Examples of technical documents regarding daylighting devices or illumination devices using artificial light energy include the following: Japanese Patent Publication No. 53-29614 discloses that a greenhouse for horticulture is equipped with a reflective plate whose angle can be adjusted through a frame. This is a reflective lighting device for greenhouses, etc. for horticulture, which has a configuration that changes the angle of the reflector in accordance with the irradiation angle of sunlight, and is
The publication describes a plant cultivation method that uses selenium or selenide as a reflector and/or filter for light rays when growing and cultivating plants. Furthermore, in JP-A-58-56617, a plurality of red, green, and blue monochromatic cathode ray tubes are arranged, and the light given to cultivated plants is adjusted by adjusting the light emission of each cathode ray tube. This is a lighting device for plant cultivation that can vary the illuminance and wavelength of energy, and these devices can be found here and there in technical literature.

要因となるものである。``Problems the invention seeks to solve'' Conventional general lighting methods are limited to simple, portable lighting methods, and are unsuitable for other types of cultivated plants. Also, according to technical documents, such as Japanese Patent Publication No. 53-29614, it is true that sunlight can be applied to areas that are rarely exposed to sunlight, such as the shadows and corners of buildings, but at least the roof is translucent. It is a necessary condition that the member has the properties. Therefore, there are problems such as, for example, ordinary houses and buildings constructed with other materials cannot be expected to receive sufficient light, and maintenance is difficult because the fixtures can be installed outdoors. Furthermore, Japanese Patent Publication No. 58-10042 describes a cultivation method that uses selenium or selenide, and the purpose and purpose of the cultivation method is that it supplements the amount of light or obtains the entire amount of light as in the present invention. it's different. Furthermore, JP-A-58-56617 utilizes artificial light energy, and is a completely different idea from the present invention, which effectively utilizes sunlight, as its gist and purpose are different. death,
There is also the problem of requiring resources. Insufficient light also causes a decline in photosynthetic activity, hindering growth, and is a major factor in reducing yields and deteriorating the quality of fruits, such as lack of sweetness.

As in the invention of JP-A No. 148010, it is a part of the focusing member and cannot sufficiently block infrared rays, or as in the invention of JP-A-59-147305, in a configuration in which the infrared filter rotates, focusing is not necessarily possible. Infrared rays are not sufficiently blocked by the components, and additional equipment is required, especially for rotating the infrared filter, making the device complex and large, making it unsuitable for general household lighting equipment for plant cultivation. There are issues such as being

向上すること等の利点がある。"Function" Next, the function of the present invention will be explained. Plants 2 grown in areas of building 1 that are hardly exposed to sunlight, such as in the shadows of other buildings or in corners, naturally receive insufficient light. However, in this invention, the reflector,
The sunlight A that has been focused through a focusing member 4 such as a convex lens is incident on an optical fiber 3, etc., and since this focusing member 4 is equipped with an infrared absorption filter 5, infrared rays are removed and mainly visible light is produced. only is incident. This incident light is propagated in a zigzag pattern within the core of the optical fiber 3 or the like disposed within the building 1, reaches its tip, and is radiated. Therefore, the plant 2 located near the tip will be irradiated, and a sufficient amount of light can be expected. In addition, as mentioned above, the infrared absorption filter 5
Since it was configured to absorb infrared rays,
Infrared rays, which have a large thermal effect when absorbed by objects and turn into thermal energy, do not enter the optical fiber 3, etc., thereby preventing burning of the optical fiber 3, etc. due to heat, and infrared rays that would otherwise enter the core are removed. Therefore, only this excluded amount of visible light is incident, and there are advantages such as an increase in the amount of visible light of the optical fiber 3, which improves its propagation ability.

A cultivated plant 2 is placed in the shade of a building or other building, or in a place that is not exposed to sunlight at all, and near this plant 2 there is an optical fiber 3 or an optical fiber cable wired inside the building 1. The tip of the optical fiber 3 or the other end of the optical fiber cable is located outside the building 1, in this example, on the roof of the building 1; positioned. Reference numeral 4 denotes a focusing member for converging sunlight A, which is made of a convex lens or a reflecting mirror. ing. Incidentally, the infrared absorption filter 5 is disposed integrally with the focusing member 4 in a stationary state. For example, as shown in FIG.
Alternatively, an infrared absorbing filter 5 (not shown) may be provided on the converging side of the focusing member 4 to remove infrared rays from the sunlight that enters the focusing member 4 in advance. The focusing member 4 is installed on the roof of the building 1 via a frame (not shown), but it may also be installed at another location by wiring the optical fiber 3 or the like, or it may be installed at a location corresponding to the irradiation angle of the sunlight A. It can also be made movable. Although the focusing member 4 equipped with the infrared absorbing filter 5 has been described above, an ultraviolet absorbing filter (not shown) may be attached thereto depending on the case.
Furthermore, by installing a spectroscopic member (not shown) such as a concave lens or a convex mirror at the tip of the optical fiber 3, it is expected that the light will be further divided and irradiated onto a wide range of plants, and that the number of optical fibers 3 will be reduced. can.

This has the effect of allowing visible light to propagate by this amount, and ultimately it can be expected to reliably and easily expand the amount of propagated light and reduce the number of optical fibers through this expansion. Through expansion, there are practical effects such as being able to provide sufficient lighting to cultivated plants in a building or achieving a reduction in the size of an infrared absorption filter.
