It is clear that using it directly as light energy is the most efficient as there is no conversion loss.For example, sunlight collected outdoors is guided through a light guide to a place that requires illumination, such as indoors. It has been proposed that the light be used as a light source for the propagation of microorganisms such as chlorella, for promoting the health of the human body, etc. Although not limited thereto, the present invention was made as part of the effective use of solar energy as described above, and utilizes solar energy that has been focused by a lens system and transmitted through a light guide. The object of the present invention is to provide a light radiator that can emit light efficiently and uniformly using a simple and inexpensive device.

照番号を付してある。The reflective member 2 has a spiral surface 2' shaped like a viscous plastic plate-like member twisted a predetermined number of times around its long axis, and has a spiral surface 2' that is parallel to the long axis and around the long axis. holes or grooves 4 for arranging the light guides 1 at predetermined angular intervals;
4..., through which the light guide 1 can be disposed and supported parallel to the long axis and at predetermined angular intervals around the long axis. . Therefore, the light emitted from the end of the light guide 1 is reflected by the reflective surface 2'' of the reflective member 2.
However, in this case, if the light emitting end of the light guide 1 is arranged at a predetermined interval along the long axis direction of the reflecting member 2, the light will be reflected over the entire length of the reflecting member 2. Therefore, light can be emitted substantially uniformly in the radial direction. The transparent cylindrical sealed container 3 is used to prevent dust from adhering to the surface of the reflective member 2 and reduce the reflection efficiency, or to prevent light from being used for culturing chlorella as described later. This is to protect the conductor from easily separating from the reflective member 2, which also serves to support the light guide, but it is not necessarily necessary depending on the usage situation.
FIG. 3 is a side view for explaining another embodiment of the present invention, in which parts having the same functions as in FIG. 1 are given the same reference numerals.

'' and is reflected by the inner wall of the transparent or translucent cylindrical sealed container 3 and radiated out of the cylindrical sealed container 3.
Therefore, the optical radiator according to this embodiment cannot emit light as uniformly as the optical radiator shown in FIG. Furthermore, since there is no need for a work step for supporting the light guide on the reflective member, the structure is simple and the manufacturing cost is low. In the embodiment shown in FIG. 3, it is also possible to make the upper end surface 3a1 of the cylindrical sealed container 3, the lower end surface 3b1, the side wall surface 3c on the light guide introduction end side, etc. semitransparent or reflective surfaces. By doing so, the light can be more effectively radiated in the radial direction of the optical radiator, which is very effective when the optical radiator according to this example is used as a light source for a chlorella culture device described later. be. In addition, in the embodiment shown in Fig. 3, it is also possible to introduce the optical conductor cable from both the upper end surface and the lower end surface of the cylindrical sealed container. can be radiated in the radial direction of the cylindrical sealed container. Figure 4 shows
This is a side view for explaining another embodiment of the present invention, and as shown in the figure, the radius of the reflecting member 2 is gradually increased along the length direction of the cylindrical sealed container 3. The light emitted in the radial direction of the light radiator can be made more uniform along the length of the light radiator.
