維持が困難となり、風圧が特に大きくなると破損してし
まうことすらあった。Conventionally, a single reflecting plate made of a paraboloid of revolution has been used to focus light rays or electromagnetic waves traveling from one direction onto one location. The reflector shown in this drawing has a large surface area when installed outdoors, and is therefore affected by wind speed.When the wind speed is high, wind pressure makes it difficult to maintain the set position and direction. If it got particularly large, it could even get damaged.

するのは困難であった。In addition, manufacturing a paraboloid of revolution is more complicated and difficult as it is larger, so an accurate paraboloid of revolution is manufactured from one large plate surface IL'1, and it also has sufficient wind pressure resistance. It was difficult to complete it as something.

かつ径は小さく、外側寄りの、前記角度の大きな反射環
５程長さは短くかつ径は大きく構成されている。The focusing section 1 is fixed on a column 4 that is erected on the pace 3. The reflecting section 2 is composed of a plurality of reflecting rings 5, 5 each made of a truncated conical surface having different angles with the axis.1 The reflecting rings 5, 5 are on the same axis The reflective ring 5a that makes the smallest angle with the axis X is located 1 lillion closer to the center X, the reflective ring 5b that makes the largest angle with the axis X is located on the outermost side, and each of the reflective rings 5, 5 The conical inner surface of each reflecting ring 5.5 serves as a reflecting surface 6 for light rays or electromagnetic waves. The angle is such that the light beam or electromagnetic wave coming in the direction of the arrow from the radiation source S located at the position shown in FIG. The length of each reflecting ring 5, 5 in the axis X direction is determined by the length of the reflecting ring 50, which captures the light ray or electromagnetic wave incident in the direction of arrow A, or the ray reflected by the reflecting surface 6 in the direction of arrow B. The length is set so as not to hinder the focusing of electromagnetic waves to the focusing portion 1, and therefore, as shown in the figure, the longer the reflecting ring 5 is arranged closer to the axis, making a smaller angle with the axis X,
In addition, the diameter is small, and the closer to the outside the reflective ring 5 is, the larger the angle, the shorter the length and the larger the diameter.
また反射部２の各反射環５，５は各相対位置を軸心Ｘ方
向に同心で僅に移動調節可能とされ、前記軸心Ｘは集束
部１を中心に回動可能とされている。Further, the respective relative positions of the reflecting rings 5, 5 of the reflecting section 2 can be adjusted by slightly moving concentrically in the direction of the axis X, and the axis X can be rotated about the focusing section 1.
本発明の反射部２は前述のごとく、多数の反射環５，５

隙が設けられているので、風が自由に通過しうるため、
風速の大な天候下においても風圧による影響が少なくな

のずれを生ずることもない。As described above, the reflecting section 2 of the present invention has a large number of reflecting rings 5, 5.
It is composed of a coaxially superimposed body of , and is shorter in the axis X direction than a conventional reflector made of a single paraboloid of revolution, and has a larger area facing the direction of the source S that can capture light rays or electromagnetic waves. Since a sufficient gap is provided between each of the reflective rings 5 and 50 constituting the reflective section 2, wind can freely pass through.
Even under weather conditions with high wind speeds, the influence of wind pressure is reduced, and therefore the installation position of the focusing device, particularly the reflecting section 2, will not be shifted due to wind pressure.
また個々の反射環５は、長さの短い截頭円錐面状であり
、単一の回転放物面よりなる従来の集中装置ｉＴと異な
り回転２次放物面でないので、その製作は容易であり、
その軸心とのなす角度も正確に形成することができる。In addition, each reflecting ring 5 has a short truncated conical shape and is not a quadratic paraboloid of rotation, unlike the conventional concentration device iT which is made of a single paraboloid of rotation, so it is easy to manufacture. can be,
The angle formed with the axis can also be accurately formed.

とするため、長さの短い各反射環５０反射面６を截頭円
錆１５面でなく、截頭円錐面に近い截頭回転放物面とす
る場合も、個々の反射環５の製作は容易である。In order to more accurately and reliably focus the light rays or electromagnetic waves on the focusing part 1, each of the short reflecting rings 50 and the reflecting surface 6 is made of a truncated rotating surface close to a truncated conical surface, rather than a truncated circular surface 15. Even when using an object surface, it is easy to manufacture each reflecting ring 5.

る。As mentioned above, in the conventional reflector made of a single paraboloid of revolution, the focusing part had to be located at focal position 1iii of the paraboloid of revolution, that is, always in front of the reflector. In the reflecting section 2 in which a large number of reflecting rings 5, 5 are arranged in a superimposed manner, the light rays or electromagnetic waves focused by the respective reflecting rings 5, 5 are reflected by the respective reflecting rings 5.5 as shown in the figure.
Since the focusing part 1 is fixed at a fixed position, the axes of the respective reflecting rings 5, 5 can be rotated around the focusing part 1, regardless of the focusing part 1. Since X can be rotationally aligned with the traveling direction of the light beam or electromagnetic wave from the radiation source S, the light beam or electromagnetic wave reflected and focused by each reflection ring 5, 5 is focused on the focusing section 1 as shown by arrow B. , it becomes extremely easy to extract the energy of a focused light beam or electromagnetic wave. Also, each reflective ring 5,5
The positioning in the axial center X direction becomes easy, the positioning mechanism between the focusing section 1 and the reflecting section 2 can be made easier, and the focusing efficiency as a focusing device can be maintained at a high level.

Depending on the type of light or electromagnetic waves to be focused, or the environmental conditions when exposed outdoors, a thin metal plate corrugated with a synthetic resin thin film and a synthetic resin surface metal plate, It may be constructed of a synthetic resin surface plated synthetic resin plate, and regardless of changes in external environmental conditions, it is possible to always maintain good focusing efficiency and reduce maintenance costs.

It is now possible to configure the reflector to be larger, making it possible to increase the area that can capture light rays or electromagnetic waves while being smaller, increasing the capture efficiency, and ensuring that there is sufficient air space between each reflective ring. Because of this, even when installed outdoors in strong winds, the wind can pass freely between the reflective rings, reducing the effects of wind pressure, without unnecessarily increasing the strength of each member. , it is lightweight, and the setting state of the entire focusing device including the reflecting section and focusing section can be maintained in good condition at all times, and each reflecting ring can be precisely and easily manufactured to the correct shape. Since the focusing part does not need to be provided in front of the reflective ring group,
The focusing section can be fixed, making it easy and reliable to take out the focused energy, and allowing only the reflecting section to rotate its axis in the direction of the radiation source. The mechanism can be simplified, the weight of the device can be reduced, and the focusing efficiency as a focusing device can be maintained at a high level. By adopting the configuration described in item 2, it is possible to finely adjust the focusing state of the light beam or electromagnetic wave, and it is possible to further enhance the function as a focusing device. As described in Section 4 or Section 5, by appropriately selecting the constituent material of the reflecting ring and the reflecting surface configuration, it is possible to maintain a reflecting surface with higher focusing efficiency and install a focusing device depending on the type of light ray or electromagnetic wave.
