【発明の詳細な説明】
（産業上の利用分野）
本発明は、例えば、太陽光発電装置の集光装置として、
また、汎用光検出素子に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applicable to, for example, a light concentrating device for a solar power generation device.
The present invention also relates to a general-purpose photodetecting element.
（従来の技術）
従来の集光型光検出装置では、光を集光検出するなめに
レンズまたは反射鏡等を、あるいは波長変換フィルム板
を必要とした。(Prior Art) Conventional condensing type photodetecting devices require a lens, a reflecting mirror, or a wavelength conversion film plate in order to condense and detect light.
（発明が解決しようとする課題）

、レンズまたは反射鏡等では、移動する光源に対して、

光能力が低下した。(Problems to be Solved by the Invention) In conventional condensing type photodetecting devices, in order to condense and detect light, a lens or a reflecting mirror or the like is used to detect a moving light source.
When the focus of the light shifts, the light-gathering ability decreases significantly, which necessitates the use of a tracking device. In addition, even in the case of a wavelength conversion film plate, when the incident light moves from a direction perpendicular to the light-receiving surface, the light-gathering ability decreases.

色素４は、励起され蛍光６を発生させる。(Means for Solving the Problems) FIG. 1 is an explanatory diagram of an omnidirectional condensing type photodetecting device of the present invention. Incident light 5 enters from the circumferential surface of the cylindrical receiver 1 and hits fluorescent dyes 4 dispersed within the cylindrical receiver 1. Fluorescent dye 4 is excited and generates fluorescence 6.

両端面で蛍光６は、外へ出る。その端面に、光検出素子
２を置いておけば光を検出できる。Fluorescence 6 generated inside the cylindrical receiver 1 travels in various directions, but due to the difference in refractive index between the cylindrical receiver 1 and the outside, it is reflected on the inner circumferential surface of the cylindrical receiver 1. Fluorescent light 6 exits from both end surfaces of 1. If a photodetector element 2 is placed on the end face, light can be detected.
（作用）
本発明の無指向性集光型光検出装置では、受光面が平面

光能力がどの点でも一定である。よって入射光が円周方
向に移動しても集光能力は変化しない。(Function) In the omnidirectional condensing photodetector of the present invention, the light receiving surface is not a flat surface but a circumferential surface of a cylindrical light receiver, so that the light condensing ability is constant at any point on the circumference. Therefore, even if the incident light moves in the circumferential direction, the light gathering ability does not change.
（実施例）

転によって起きる太陽光の移動に対しても集光能力が常
に一定であるので、追尾装置を必要としない。(Example) The following is an example of the present invention. When the omnidirectional condensing photodetector of the present invention is used as a sunlight concentrator, it can also be used to condense sunlight against movement of sunlight caused by the rotation of the earth. Since the optical power is always constant, no tracking device is required.

きる。Furthermore, when used as a solar power generation device, the output power from the photodetector, such as a solar cell, is always constant with respect to the movement of sunlight, which means that when using a tracking device, The conversion efficiency of the DC/AC converter can be improved compared to a conventional fixed type solar power generation device in which the output power changes with the movement of the sun.
また、汎用光検出素子においても、円柱受光器の円周面

えるばかりではなく、円柱受光器の円柱の長さにより、
受光器の受光面積を任意に決めることができる。In addition, even in general-purpose photodetecting elements, there is no directivity on the circumferential surface of the cylindrical photodetector, and it can not only be treated as an omnidirectional condensing photodetecting device, but also due to the length of the cylinder of the cylindrical photodetector.
The light receiving area of the light receiver can be arbitrarily determined.

ての光を同時に集光検出することもできる効果がある。(Effects of the Invention) The omnidirectional condensing photodetector of the present invention does not require the use of lenses, reflectors, etc. to condense and detect light.
There is also no need to track a moving light source.This is because the light-receiving surface of the cylindrical receiver is not a flat surface but the circumferential surface of the cylinder, so the light-gathering ability is constant at any point on the circumference. This is due to a number of reasons. Therefore, even if the incident light moves in the circumferential direction, the light-gathering ability does not change.Furthermore, the omnidirectional condensing photodetector of the present invention can simultaneously condense all the light coming from the circumferential direction of the cylinder. There are effects that can also be detected.
