た。The present applicant first focused sunlight using a lens or the like, introduced it into a light guide, and transmitted it to any desired location through the light guide for use in lighting or other purposes. We proposed various devices. Furthermore, in order to protect the lens from wind, rain, dust, etc., it has also been proposed to house the sunlight collecting device in a transparent capsule.

っている。As is well known, the solar light collecting device includes, for example, a large number of lenses 6, a parabolic concentrator, or a reflecting mirror, and the sunlight focused by the lenses or the parabolic concentrator is introduced into the optical conductor cable. The sunlight reflected by the reflected light is introduced into a light conduit or the like and transmitted to any desired location through the guide cable or light conduit.

に製造することが困難であった。Therefore, in the solar collector device as described above, conventionally,
The above-mentioned transparent capsule was made of acrylic, but since the transparent capsule introduces sunlight into the capsule, its surface was finished with a mirror finish to reduce light loss due to diffused reflection, etc. It is necessary to make the light homogeneous so that the light entering the capsule effectively reaches the lens, parabolic concentrator, or reflector. However, if transparent capsules are manufactured by injection molding or compression molding, it is difficult to achieve a mirror finish on the surface or to achieve a uniform finish on the whole, making it difficult to manufacture transparent capsules with desired characteristics at a low cost.

仕上げされている。Fig. 1 is a cross-sectional configuration diagram for explaining one embodiment of the present invention, and Fig. 2 is a plan view. In the figure, 10 is a lower mold, 2o is an upper mold, and Both the upper mold 2 and the upper mold 2 are approximately hemispherical, and the inner surface of the lower mold 10 and the outer surface of the upper mold 20 are mirror-finished.

厚さを均一にするもの−である。The inner surface of the lower mold and the outer surface of the upper mold are configured as concentric circles, and the radius of the upper mold is slightly smaller than the radius of the lower mold, and specifically corresponds to the wall thickness of the transparent capsule to be manufactured. It's getting smaller accordingly. 30 is the lower mold 10 and the upper mold 20
This capsule 30 is manufactured using the lower mold 10 and the upper mold 20 in the following manner, for example. First, when using the illustrated lower mold 10 and upper mold 20, a heating wire 11 made of nichrome wire or the like is formed on the outer surface of the lower mold 10, and a heating wire 21 of the same wire is formed on the inner surface of the upper mold 20. are arranged approximately equally, and are connected to a control device (not shown) through lead wires 12, 22, respectively. Further, the lower mold 10 and the upper mold 20 each have a flange portion 13° 23 on the opening side, and a spacer 1 having a uniform thickness over the entire circumference is provided on the outer circumference of the upper surface of the flange 13 of the lower mold.
4, and a large number of grooves 15 extending in the radial direction are provided on the upper surface of the spacer 14. This flange part 1
3.23 is the flange part 3 on the molded transparent capsule 30
This is for molding the lower mold 1 at the same time.

たされる。When manufacturing a transparent capsule using the lower mold 10 and upper mold 20 as described above, the lower mold 10 and the upper mold 20 are separated, and a predetermined amount of transparent resin, such as acrylic resin, is poured into the lower mold 10. At this time, the resin may be in a solid state or a molten state, and in any case, the lower mold 10 is heated by the heating wire 11 to bring the resin into a molten state. In this state, when the upper mold 20 is pushed into the lower mold 10, the space between the inner surface side of the lower mold 10 and the outer surface side of the upper mold 20 becomes narrower as it is pushed in. The resin 30 in this state flows in the direction of the arrow due to its fluidity, and when the upper mold 20 reaches the state shown in the figure, that is, when the upper mold 20 completely rests on the spacers 14 of the lower mold 10, The space formed by the lower mold 10, upper mold 20, and spacer 14 is filled with resin.

きる。That is, since the volume of the space formed by the lower mold 10, the upper mold 20, and the spacer 14, the coefficient of thermal expansion of the resin, etc. are known in advance, the amount of resin to be initially introduced can be determined from this. Therefore, as mentioned above, the lower mold 10 and the upper mold 20 are in the specified position! When brought into relationship, the resin may be exactly as shown.

みを生じないようにするものでもある。As described above, the present invention effectively utilizes the fluidity of the resin to form a substantially hemispherical transparent dome. When the space formed by the lower mold 10, the upper mold 20, and the spacer 14 gradually becomes narrower as described above, air is trapped in this space, inhibiting the flow of the resin or causing local pressure. This was provided to prevent the molded product from becoming non-uniform due to overheating, but at the same time, it also prevents the molded capsule from becoming distorted due to the flow of a slightly larger amount of resin. There is also.

理解できよう。Furthermore, as described above, the present invention utilizes the fluidity of the resin, but this fluidity is dependent on temperature, and if the temperature of the lower mold 10 and the upper mold 20 is low, the resin will flow less easily. , the temperature at the tip of the flow becomes low, which not only deteriorates the fluidity but also impairs the homogeneity. Heating wires made of nichrome wire or the like are arranged evenly on the sides and the inner surface of the upper mold 20, and these heating wires maintain the lower mold 10 and the upper mold 20 at a desired temperature to improve the fluidity of the resin. It is maintained constant. After the space formed by the lower mold 10, upper mold 20, and spacer 14 is filled with the resin 30 as described above, the heating wire is turned off and the temperature of the fluid such as gas, vapor, or liquid is controlled. In other words, the entire body is cooled while gradually lowering the temperature to harden the resin, and then the upper mold 20 is removed and the molded capsule 3 is removed.
Take out 0. In addition, in the above, the lower mold 10 and the upper mold 20
We explained an example of temperature control by installing a heating wire in the
The temperature control of the upper mold and the lower mold, and the temperature control of melting and solidification of the resin, etc., are not limited to the above-mentioned embodiments. It will be readily understood that the temperature may be controlled by injection of fluid such as gas, steam, or liquid, or the temperature of the entire room may be controlled.

り均一に温度制御することができる。FIG. 3 is a sectional view for explaining another embodiment of the heating means, in which the outer surface of the lower mold 10 is formed as a part of the fluid flow path wall on the outer surface side of the lower mold 10. A fluid flow path forming body 40 is provided to form a flow path 41, and a flow path 51 is formed on the inner surface side of the upper mold 20, with the inner surface of the upper mold 20 serving as a part of the fluid flow path wall. A fluid flow path forming body 50 is provided in the fluid flow paths 41 and 51, and a temperature-controlled fluid is passed through the fluid flow paths 41 and 51 as shown by the arrows ○ and A. Since the temperature of the upper mold is constant throughout, no localized high temperature or low temperature areas occur, allowing more uniform temperature control.
