Description
本發明係有關一種將來自外部的太陽光於建築物的室內導光，照明室內之光傳送裝置。The present invention relates to an optical transmission device for guiding sunlight from the outside to a room of a building to illuminate the room.
近年來，省能源及減少二氧化碳之排出以進行環境保護之必要性受到矚目，作為用以因應該要求之手段之一，係有如下之提議，即，經由以反射率高之構件來構成內面之通道而將太陽光取入室內，俾作為照明光源利用之光傳送裝置(參照下述專利文獻)。In recent years, the need to save energy and reduce the emission of carbon dioxide for environmental protection has attracted attention. As one of the means for responding to the demand, there is a proposal to form an inner surface via a member having a high reflectance. In the channel, the sunlight is taken into the room, and the light is used as an illumination source (see the following patent document).
此種裝置由於可不將能量轉換為電氣等其他的能量而直接加以使用，故能源利用效率高，對於省能源及減少二氧化碳之排出係有貢獻。Since such a device can be directly used without converting energy into other energy such as electricity, the energy utilization efficiency is high, and it contributes to energy saving and carbon dioxide emission reduction.
譬如，專利文獻1之光傳送裝置，如專利文獻1之第5圖所示，係以採入太陽光(自然光)1之採光口2，以及將太陽光(自然光)1導入室內之光通道4而構成。光通道4係如第4(b)圖所示，剖面為矩形狀，內面以作為反射面之筒狀構件而構成。由採光口2採入之太陽光(自然光)1係邊於光通道4內反射邊受到導引，再由光取出口8而向室內6送光。由於光傳送裝置必須將採入之光效率良好地導入室內，故筒狀構件之內面係以正反射率高之材料構成。For example, the optical transmission device of Patent Document 1, as shown in Fig. 5 of Patent Document 1, is a lighting port 2 for collecting sunlight (natural light) 1, and a light channel 4 for introducing sunlight (natural light) 1 into the room. And constitute. As shown in Fig. 4(b), the optical channel 4 has a rectangular cross section, and the inner surface is formed of a cylindrical member as a reflecting surface. The sunlight (natural light) 1 collected by the lighting port 2 is guided while being reflected by the light passage 4, and is then sent out to the room 6 by the light extraction port 8. Since the light transmitting device must efficiently introduce the collected light into the room, the inner surface of the tubular member is made of a material having a high regular reflectance.
又，於筒狀構件進行加工時需要進行彎折加工，而加 工部易破裂之材料並不適用。此時，以加工性優異之材料形成筒狀物，並於該筒狀物之各面貼附高反射板之平板來形成光傳送裝置。如此，貼附平板時，需較多的材料費且加工步驟數增加，製造成本提高。Moreover, it is necessary to perform bending processing when processing the cylindrical member, and Materials that are easily broken by the Ministry of Construction are not applicable. At this time, a cylindrical material is formed of a material having excellent workability, and a flat plate of a high-reflection plate is attached to each surface of the cylindrical body to form an optical transmission device. Thus, when the flat plate is attached, a large material cost is required, the number of processing steps is increased, and the manufacturing cost is increased.

然而，即使筒狀構件之內面的正反射率高，依加工方法，光的傳送效率仍會有大幅變化。However, even if the regular reflection rate of the inner surface of the cylindrical member is high, the light transmission efficiency largely changes depending on the processing method.
又，不易以一體物來構成光傳送裝置，且多有藉由連結多數筒狀構件而構成之情況。此時，依筒狀構件之連結方法，光的傳送效率亦會大幅變化。進而，必須使用可於筒狀物進行加工之材料。Further, it is difficult to form the optical transmission device as a single body, and many of them are configured by connecting a plurality of cylindrical members. At this time, depending on the method of connecting the tubular members, the light transmission efficiency also largely changes. Further, it is necessary to use a material that can be processed in a cylinder.
本發明係有鑑於上述習知之問題點而創作完成者，目的在於提供一種可效率良好地傳導太陽光之光傳送裝置。The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an optical transmission apparatus that can efficiently transmit sunlight.
依本發明之一觀點，係提供一種光傳送裝置，具有取入太陽光之採光部，且將由該採光部取入之前述太陽光導至室內，於室內放光者，其特徵在於包含有：筒狀構件，係彎折以金屬為主材料之板體，並藉由固定該板體相對向之端部群而形成為筒狀者；及帶狀構件，係捲繞端面群碰 接而連結之二個前述筒狀構件之連結部，固定該二個筒狀構件者。According to one aspect of the present invention, there is provided an optical transmission device comprising: a lighting unit that takes in sunlight, and directs the sunlight taken in by the lighting unit into a room, and emits light indoors, and is characterized in that: The member is formed by bending a plate made of a metal as a main material, and is formed into a tubular shape by fixing the opposite end groups of the plate body; and the band member is a group of winding end faces The connecting portions of the two tubular members that are connected to each other are used to fix the two tubular members.
依本發明之光傳送裝置，由於只需將帶狀構件捲繞於連結部就可固定二個筒狀構件，因此光傳送裝置中，完全不會有在與傳送方向為相對側處反射光之障礙物。因此，進入光傳送裝置內之太陽光不會於該連結部返回原處，可反覆進行反射而往前進。故，可提高光之傳送效率。又，只需將帶狀構件捲繞於連結部就可固定二個筒狀構件，因此連結作業係為簡單。According to the optical transmission device of the present invention, since the two tubular members can be fixed by winding the band member around the joint portion, the light transmitting device does not reflect light at the side opposite to the conveying direction. obstacle. Therefore, the sunlight entering the light transmitting device does not return to the original portion of the connecting portion, and can be reflected and moved forward. Therefore, the light transmission efficiency can be improved. Further, since the two tubular members can be fixed by winding the band member around the connecting portion, the connecting operation is simple.
再者，帶狀構件宜以金屬為主材料，且位於前述筒狀構件側之表面宜為光反射面。藉此，二個筒狀構件之連結部即便多少有些間隙，亦可防止光洩漏，故對於提高光之傳送效率係有助益。Further, the strip member is preferably made of a metal material, and the surface on the side of the cylindrical member is preferably a light reflecting surface. Thereby, even if there is a slight gap between the joint portions of the two tubular members, light leakage can be prevented, which is advantageous for improving the light transmission efficiency.
依本發明之另一觀點，係提供一種光傳送裝置，具有取入太陽光之採光部，且將由該採光部取入之前述太陽光導至室內，於室內放光者，其特徵在於包含有：筒狀構件，係彎折以金屬為主材料之板體，並藉由固定該板體相對向之端部群而形成為筒狀者；及凸緣部，係設置於各前述筒狀構件之端部者；藉由讓前述凸緣部群碰接且加以固定而連結前述筒狀構件。According to another aspect of the present invention, there is provided an optical transmission apparatus comprising: a lighting unit that takes in sunlight, and directs the sunlight taken in by the lighting unit into a room, and emits light indoors, and includes: The tubular member is formed by bending a plate made of a metal as a main material, and is formed into a tubular shape by fixing the end portion of the plate body opposite thereto; and the flange portion is provided in each of the cylindrical members The end member is connected to the tubular member by abutting and fixing the flange portion group.
依本發明之其他的光傳送裝置，係藉由設置於筒狀構件之凸緣部而連結筒狀構件群，因此於光傳送裝置內，完全不會有在與傳送方向為相對側處反射光之障礙物。故，進入光傳送裝置內之太陽光不會於該連結部加以折返，可 反覆進行反射而往前進。因此，可提高光的傳送效率。According to another optical transmission device of the present invention, since the cylindrical member group is connected to the flange portion of the tubular member, no light is reflected in the optical transmission device at the side opposite to the transport direction. Obstacle. Therefore, the sunlight entering the light transmitting device does not fold back at the connecting portion. Repeat the reflection and move forward. Therefore, the light transmission efficiency can be improved.
依本發明之光傳送裝置，雖連結多數筒狀構件，但於光傳送裝置內，完全不會有在與傳送方向相對側處反射光之障礙物，故可提高光之傳送效率。According to the optical transmission device of the present invention, since a large number of cylindrical members are connected, in the optical transmission device, there is no obstacle that reflects light at the side opposite to the transport direction, so that the light transmission efficiency can be improved.

光傳送裝置101係以螺栓、螺帽等而安裝於固定在屋內的樑11之光傳送裝置固定部10。將光傳送裝置101固定於光傳送裝置固定部10，係利用光傳送裝置101之帶狀構件7來進行。即，讓螺栓9通過設置於帶狀構件7之孔穴8與設置於光傳送裝置固定部10之孔穴9，並以未圖示之螺帽加以緊固而固定光傳送裝置101。又，實際上於房屋雖有屋頂與天花板但第1圖中省略。The optical transmission device 101 is attached to the optical transmission fixing portion 10 of the beam 11 fixed in the house by bolts, nuts, or the like. Fixing the optical transmission device 101 to the optical transmission device fixing portion 10 is performed by the band member 7 of the optical transmission device 101. In other words, the bolt 9 is passed through the hole 8 provided in the belt-shaped member 7 and the hole 9 provided in the optical transmission fixing portion 10, and is fastened by a nut (not shown) to fix the optical transmission device 101. In addition, although the house has a roof and a ceiling, it is omitted in FIG.
(採光部之構成)(Composition of the lighting department)
本實施形態中，光傳送裝置101之採光部1的採光面， 如第1圖所示，係形成為相對於水平面而傾向南側，即，南側較北側低地形成。採光面之傾斜度宜依太陽為正午時之高度而適宜地設定，俾使得採入之光量為最多。In the embodiment, the lighting surface of the lighting unit 1 of the optical transmission device 101 is As shown in Fig. 1, it is formed to be inclined to the south side with respect to the horizontal plane, that is, the south side is formed lower than the north side. The inclination of the lighting surface should be appropriately set according to the height of the sun at noon, so that the amount of light collected is the most.
採光面係依筒狀構件之剖面形狀而有各種形狀。作為四角形狀之採光面的配置方式，可以有讓採光面之一邊朝南向，並讓其一邊為最低地加以配置之方式，抑或讓採光面之頂點朝南向，並讓其頂點最低地加以配置之方式等。採光面係譬如沿傾斜的平面，裁切光傳送裝置之端部(採光部)而形成。The lighting surface has various shapes depending on the cross-sectional shape of the tubular member. As a configuration of the four-corner lighting surface, one side of the lighting surface may be oriented southward, and one side may be disposed at a minimum, or the apex of the lighting surface may be oriented southward, and the apex of the lighting surface may be minimized. Configuration method, etc. The lighting surface is formed, for example, along an inclined plane and cuts an end portion (lighting portion) of the light transmitting device.

(筒狀構件之構造及製造方法)(Structure and manufacturing method of cylindrical member)
第2(a)乃至(c)圖係顯示本發明第1實施形態之筒狀構件之構造及製造方法的剖面圖。2(a) to 2(c) are cross-sectional views showing the structure and manufacturing method of the tubular member according to the first embodiment of the present invention.
筒狀構件12乃至14，係以本體12a,13a,14a與位於外側之凸部(固定板體緣部之部分)12b,13b,14b構成。本體12a,13a,14a之內壁係作為正反射率高之反射面。The tubular members 12 to 14 are constituted by the bodies 12a, 13a, 14a and the convex portions (portions of the fixed plate body edges) 12b, 13b, 14b located on the outer side. The inner walls of the bodies 12a, 13a, 14a serve as reflecting surfaces having a high regular reflectance.
本體12a,13a,14a之剖面形狀可為圓形者(第2(a)圖)、正方形13a者(第2(b)圖)或長方形14a者(第2(c)圖)，抑或雖未圖示，但亦可為其他的多角形及橢圓形者。凸部(固定板體緣 部群之部分)12b,13b,14b為保持其等之形狀，係施有所謂卷邊加工之處。目前市售之正反射率高的材料中，於卷邊加工部都會部分地斷裂，無法進行此卷邊加工。因此，有無法於具有卷邊加工部之筒狀構件施行加工之問題。The cross-sectional shape of the main bodies 12a, 13a, 14a may be circular (second (a)), square 13a (second (b)) or rectangular 14a (second (c)), or not The figure, but can also be other polygons and ovals. Convex (fixed plate body edge) The parts of the group) 12b, 13b, and 14b are so-called hemming processing places in order to maintain their shape. Among the commercially available materials having a high positive reflectance, the hemming processing portion is partially broken, and the hemming processing cannot be performed. Therefore, there is a problem that it is impossible to perform processing on the tubular member having the hemming working portion.
筒狀構件12乃至14係如下述地加以製作。The tubular members 12 to 14 are produced as follows.
以金屬為主材料之正方形或長方形之板體相對向的兩緣邊部中，將一側的緣邊部往下側彎折而形成第1鉤狀部，並將另一側之緣邊部往上側彎折而形成第2鉤狀部。接著，將板體捲曲或彎折成剖面為預定的形狀，讓板體相對向之兩緣邊部排整，將第1鉤狀部的彎折部分***第2鉤狀部之中。其次，按壓填住鉤狀部而加以固定。施行所謂卷邊加工。Among the two rim portions in which the square or rectangular plate body of the metal-based material is opposed, the one edge portion is bent downward to form the first hook portion, and the other side edge portion is formed. The upper side is bent to form a second hook portion. Next, the plate body is crimped or bent into a predetermined shape, and the plate body is aligned with respect to both edge portions, and the bent portion of the first hook portion is inserted into the second hook portion. Next, the hook is pressed and fixed to fix it. The so-called hemming processing is performed.
筒狀構件12乃至14之具體例係如下述實施例所述。Specific examples of the tubular members 12 to 14 are as described in the following embodiments.

第3圖、第4圖係顯示本發明第1實施形態之筒狀構件的連結方法及連結部之構造之圖，第3(a)圖係立體圖，第3(b)圖係筒狀構件連結後由第3(a)圖之I方向所示之側面圖，第4圖係沿著第3(b)圖之Ⅱ-Ⅱ線的剖面圖。任一者皆顯示筒狀構件之剖面形狀為圓形的態樣。3 and 4 are views showing a connection method of a tubular member according to the first embodiment of the present invention and a structure of a connection portion, a perspective view of a third (a) diagram, and a connection of a tubular member of a third (b) diagram. The side view shown by the direction I of Fig. 3(a), and Fig. 4 is a cross-sectional view taken along line II-II of Fig. 3(b). Either one of them shows a circular shape of the cylindrical member.
有關筒狀構件之連結方法，如第3(a)圖所示，首先，讓二個筒狀構件4及5之凸部4b,5b碰接，讓二個筒狀構件4及5的端面群相接觸地加以連結。Regarding the method of joining the tubular members, as shown in Fig. 3(a), first, the convex portions 4b, 5b of the two cylindrical members 4 and 5 are brought into contact, and the end faces of the two cylindrical members 4 and 5 are brought together. Connected in contact.
其次，準備寬度為5cm程度，且長度係較筒狀構件之外側圓周多長出某程度的較長之帶狀構件7。帶狀構件7之材 料可使用與筒狀構件之材料相同，以金屬為主材料之帶狀的板體。一面宜為正反射率高之光反射面。Next, a long strip-shaped member 7 having a width of about 5 cm and a length longer than the outer circumference of the tubular member is prepared. The material of the strip member 7 As the material of the cylindrical member, a strip-shaped plate body mainly composed of metal can be used. One side should be a light reflecting surface with a high regular reflectance.
接著，以帶狀構件7捲繞二個筒狀構件4及5的連結部之周圍，俾讓帶狀構件7之光反射面為面向二個筒狀構件4及5的連結部。如第3(a)圖所示之帶狀構件7，係顯示實際上拔出捲繞連結部之周圍時的形狀。即，帶狀構件7係沿著包含有凸部4b,5b之筒狀構件4及5的外周而加以捲繞，帶狀構件7一側之端部與另一側之端部係於凸部4b,5b之上方疊合而加以固定。參照第4圖，進而詳細說明於凸部4b,5b周邊之帶狀構件7之構造時，帶狀構件7係一側的端部於凸部4b,5b之側部的下側加以彎折，且另一側之端部於凸部4b,5b之上部加以彎折，讓一側之端部與另一側之端部在凸部4b,5b之上方疊合而加以固定。一側之端部與另一側之端部的固定，如第1圖及第4圖所示，係於將光傳送裝置101安裝於室內的光傳送裝置固定部10時，同時進行。固定之手段可為習知者，譬如此實施形態，可適用經由帶狀構件7一側之端部與另一側端部之孔穴8而進行的螺栓、螺帽的固定方法。或者亦可適用螺釘及點熔接之固定方法。又，光傳送裝置101固定於室內且支撐於帶狀構件7時，帶狀構件7雖會彎折但不會拉展，係保持於第4圖之形狀。Next, the belt-shaped member 7 is wound around the connecting portions of the two tubular members 4 and 5, and the light reflecting surface of the belt-shaped member 7 is a connecting portion facing the two cylindrical members 4 and 5. The strip-shaped member 7 shown in Fig. 3(a) shows the shape when the periphery of the winding joint portion is actually pulled out. That is, the belt-shaped member 7 is wound around the outer circumference of the tubular members 4 and 5 including the convex portions 4b, 5b, and the end portion on the side of the belt-shaped member 7 and the end portion on the other side are attached to the convex portion. 4b, 5b are superimposed and fixed. Referring to Fig. 4, in detail, in the structure of the strip-shaped member 7 around the convex portions 4b, 5b, the end portion of the strip-shaped member 7 side is bent at the lower side of the side portions of the convex portions 4b, 5b. The other end portion is bent at the upper portion of the convex portions 4b, 5b, and the end portion of the one side and the other end portion are superposed on the convex portions 4b, 5b to be fixed. The fixing of the end portion on one side and the end portion on the other side is performed simultaneously when the optical transmission device 101 is attached to the optical transmission device fixing portion 10 in the room as shown in Figs. 1 and 4 . The means for fixing may be a conventional embodiment, and a method of fixing a bolt or a nut through the hole 8 on the side of the belt-shaped member 7 and the other end may be applied. Or it can be applied to the fixing method of screws and spot welding. Further, when the optical transmission device 101 is fixed indoors and supported by the belt-shaped member 7, the belt-shaped member 7 is bent but does not stretch, and is held in the shape of Fig. 4.
如此，藉由包覆凸部4b,5b且固定帶狀構件7，可防止狀構件4,5之旋轉及其他動作而更加強固地固定筒狀構件4,5。As described above, by covering the convex portions 4b, 5b and fixing the band-shaped member 7, the rotation of the members 4, 5 and other operations can be prevented, and the tubular members 4, 5 can be more firmly fixed.
以上，依第1實施形態，由於只需將帶狀構件7捲繞於 連結部就可固定二個筒狀構件4,5，故於光通道內完全不會有在與傳送方向為相對側處反射光之障礙物。因此，第1圖中，由連結部之左側進入的太陽光，不會在此連結部折返回原點(左側)，可反覆地進行反射而向右側前進。是故，可提高光的傳送效率。As described above, according to the first embodiment, it is only necessary to wind the band member 7 around The connecting portion can fix the two cylindrical members 4, 5, so that there is no obstacle in the optical passage that reflects light at the side opposite to the conveying direction. Therefore, in the first drawing, the sunlight entering from the left side of the connecting portion is not folded back to the origin (left side) at the connecting portion, and can be reflected and moved forward to the right side. Therefore, the light transmission efficiency can be improved.
又，由於只需將帶狀構件7捲繞於連結部就可固定二個筒狀構件4,5，因此連結作業係為簡單。Further, since the two tubular members 4, 5 can be fixed by simply winding the band member 7 around the connecting portion, the connecting operation is simple.
進而，捲繞帶狀構件7，俾讓帶狀構件7之光反射面為面向二個筒狀構件4及5的連結部，且帶狀構件7係支撐光傳送裝置並且帶狀構件7之光反射面可充分地覆蓋連結部，因此即使於二個筒狀構件4及5的連結部多少出現間隙，亦可藉由帶狀構件7之光反射面而反射由間隙洩漏出之光並使其返回筒狀構件4及5內。藉此，可防止光洩漏，提高光的傳送效率。Further, the belt-shaped member 7 is wound so that the light-reflecting surface of the belt-shaped member 7 is a joint portion facing the two cylindrical members 4 and 5, and the belt-shaped member 7 supports the light-transmitting device and the light of the belt-like member 7 Since the reflecting surface can sufficiently cover the connecting portion, even if a gap is formed between the connecting portions of the two tubular members 4 and 5, the light leaking from the gap can be reflected by the light reflecting surface of the strip member 7 and Return to the inside of the tubular members 4 and 5. Thereby, light leakage can be prevented and the light transmission efficiency can be improved.
(第2實施形態)(Second embodiment)
(光傳送裝置之整體構成)(The overall structure of the optical transmission device)
第2實施形態之光傳送裝置除二個筒狀構件本身之構造，及二個筒狀構件之連結部的構造外，係具有與第1圖之光傳送裝置之整體構成相同的整體構成。The optical transmission device according to the second embodiment has the same overall configuration as the overall configuration of the optical transmission device of Fig. 1 except for the structure of the two tubular members themselves and the structure of the connection portions of the two tubular members.
(筒狀構件之構造)(construction of cylindrical member)
第5(a)圖係顯示本發明第2實施形態之筒狀構件的構造之立體圖。顯示筒狀構件之剖面為圓形之態樣。Fig. 5(a) is a perspective view showing the structure of the tubular member according to the second embodiment of the present invention. The cross section of the cylindrical member is shown to be circular.
筒狀構件之本體15a,16a與凸部15b,16b係使用與第1實施形態相同構造者，但第2實施形態之筒狀構件15,16係與 第1實施形態不同，進而於筒狀構件之本體15a,16a及凸部15b,16b之端部設置凸緣部15c,16c。凸緣部15c,16c係譬如藉由熔接而設置於本體15a,16a及凸部15b,16b。第5(a)圖中，標號15b,16b係位於施有所謂卷邊加工之外側，為凸部(固定板體緣部群之部分)。The main bodies 15a, 16a and the convex portions 15b, 16b of the tubular member are the same as those of the first embodiment, but the tubular members 15, 16 of the second embodiment are In the first embodiment, the flange portions 15c and 16c are provided at the end portions of the main bodies 15a and 16a and the convex portions 15b and 16b of the tubular member. The flange portions 15c, 16c are provided to the bodies 15a, 16a and the projections 15b, 16b, for example, by welding. In Fig. 5(a), reference numerals 15b and 16b are located on the side other than the so-called hemming processing, and are convex portions (portions of the edge portion of the fixed plate body).
又，筒狀構件之本體15a及16a之剖面形狀為圓形外，亦可適用矩形或多角形。Further, the main bodies 15a and 16a of the tubular member have a circular cross-sectional shape, and a rectangular shape or a polygonal shape may be applied.
再者，第5(a)圖中，雖僅於筒狀構件之本體15a,16a與凸部15b,16b之一端設置凸緣部15c,16c，但進而連結新的筒狀構件時，亦可於筒狀構件之本體15a,16a與凸部15b,16b之兩端設置凸緣部15c,16c。Further, in the fifth (a) diagram, the flange portions 15c and 16c are provided only at one of the main bodies 15a and 16a of the tubular member and the convex portions 15b and 16b. However, when a new tubular member is connected, Flange portions 15c, 16c are provided at both ends of the main bodies 15a, 16a and the convex portions 15b, 16b of the tubular member.
(筒狀構件之連結方法及連結部之構造)(Connection method of tubular member and structure of connecting portion)
第5(a)、(b)圖係顯示本發明第2實施形態之筒狀構件之連結方法及連結部的構造之圖，第5(a)圖為立體圖，第5(b)圖為筒狀構件連結後之側面圖。5(a) and 5(b) are views showing a method of connecting the tubular members and a structure of the connecting portion according to the second embodiment of the present invention, wherein FIG. 5(a) is a perspective view, and FIG. 5(b) is a tube. Side view of the connected members.
如第5(a)圖所示，將剖面為圓形且於兩側具有凸緣部15c,16c之二個筒狀構件15,16，在連接凸緣部15c,16c後，讓螺栓通過於設置在凸緣部15c,16c之孔穴15d,16d並以螺帽加以緊固，藉此而固定凸緣部15c,16c並連結二個筒狀構件15,16。此時，宜讓二個筒狀構件15,16之相互的凸部15b,16b之位置一致地而進行連結。又，固定凸緣部15c,16c之方法，除藉由螺栓、螺帽固定之方法外，亦可為習知者，譬如可適用藉由螺釘固定之方法，或是藉由點熔接固定之方法等。As shown in Fig. 5(a), the two cylindrical members 15, 16 having a circular cross section and having flange portions 15c, 16c on both sides are passed through the flange portions 15c, 16c to allow the bolt to pass through. The holes 15d, 16d provided in the flange portions 15c, 16c are fastened by nuts, thereby fixing the flange portions 15c, 16c and connecting the two cylindrical members 15, 16. At this time, it is preferable to connect the positions of the convex portions 15b and 16b of the two tubular members 15 and 16 in unison. Moreover, the method of fixing the flange portions 15c, 16c may be a conventional method other than a method of fixing by a bolt or a nut, such as a method of fixing by screws or a method of fixing by spot welding. Wait.
將此實施形態之光傳送裝置固定於屋內時，係利用凸 緣部15c,16c而進行。即，通過凸緣部15c,16c之孔穴15d,16d的螺栓，係進而通過如第1圖所示之屋內的光傳送裝置固定部10之孔穴，並藉由螺帽加以緊固而將凸緣部15c,16c固定於光傳送裝置固定部10。When the optical transmission device of this embodiment is fixed in the house, the convexity is utilized. The edges 15c, 16c are performed. That is, the bolts passing through the holes 15d, 16d of the flange portions 15c, 16c are further passed through the holes of the fixing portion 10 of the optical transmission device in the room as shown in Fig. 1, and are fastened by the nuts to be convex. The edge portions 15c, 16c are fixed to the optical transmission device fixing portion 10.
如以上，依本發明第2實施形態之筒狀構件，由於係藉由設置在筒狀構件15及16之本體15a,16a外部的凸緣部15c,16c來連結二個筒狀構件15及16，故於光傳送裝置內，完全不會有在與傳送方向相對側處反射光之障礙物。是故，於第1圖中由連結部之左側進入的太陽光，不會在該連結部返回原處(左側)，係反覆地進行反射而向右側前進。因此，可提高光的傳送效率。As described above, in the tubular member according to the second embodiment of the present invention, the two cylindrical members 15 and 16 are connected by the flange portions 15c and 16c provided outside the main bodies 15a and 16a of the tubular members 15 and 16. Therefore, in the optical transmission device, there is no obstacle at all in the side opposite to the conveying direction. Therefore, in the first drawing, the sunlight entering from the left side of the connecting portion does not return to the original portion (left side) at the connecting portion, and is reflected repeatedly and proceeds to the right side. Therefore, the light transmission efficiency can be improved.

The acrylic resin was coated on the film with a thickness of 10 μm, and then silver plating (silver mirror reaction) was applied to the acrylic resin at a thickness of 100 nm, and the acrylic resin was coated with a thickness of 1 μm on the silver plating. Thereby, a plate made of a metal having a light reflection surface having a high positive reflectance as a main material (reflectance: 95%) was obtained. The plate body was formed into a tubular member having a square cross-sectional shape of 13.3 mm and having a length of 17 cm, and the opposite ends of the plate body were subjected to hemming processing and fixed. In this manner, three inner wall systems were fabricated as the tubular members of the light reflecting surface.

The cross-sectional area of the tubular member is the same as the cross-sectional area of the tubular member of the second embodiment.
(比較例1)(Comparative Example 1)
使用板厚0.2mm之電鍍鋅鋼板(一面之鍍鋅量：10g/m2 、雙面鍍敷)，並於其表面進行鉻酸鹽處理，被覆25mg/m2 之Cr，並於一面之Cr被膜上以厚度10μm而被覆丙烯酸樹脂，其次，於丙烯酸樹脂上以厚度100nm被覆鍍銀(銀鏡反應)，進而，於鍍銀上以厚度1μm被覆丙烯酸樹脂。藉此，獲致以具有高正反射率之光反射面的金屬為主材料之板體(反射率：95%)。捲繞該板體，形成內徑為ψ 15cm、長度為51cm且剖面形狀為圓形的筒狀構件，並於板體相對向之緣部施行卷邊加工並加以固定。An electrogalvanized steel sheet having a thickness of 0.2 mm (galvanizing amount of one side: 10 g/m 2 , double-sided plating) was used, and chromate treatment was applied to the surface thereof to coat Cr of 25 mg/m 2 and Cr on one side. The acrylic resin was coated on the film with a thickness of 10 μm, and then silver plating (silver mirror reaction) was applied to the acrylic resin at a thickness of 100 nm, and the acrylic resin was coated with a thickness of 1 μm on the silver plating. Thereby, a plate made of a metal having a light reflection surface having a high positive reflectance as a main material (reflectance: 95%) was obtained. The plate body was wound to form a cylindrical member having an inner diameter of 15 cm and a length of 51 cm and a circular cross section, and was crimped and fixed to the opposite edge portion of the plate body.

The plate body was wound to form a cylindrical member having an inner diameter of 15 cm and a length of 51 cm and a circular cross section. Although the edge of the plate body was subjected to crimping, a part of the crimped portion was damaged. . As described above, in Comparative Example 2, the characteristics were not evaluated because the hemming working portion was broken.
如此，製作以一個內壁作為光反射面且內徑為ψ 15cm、長度為51cm之筒狀構件而構成的光傳送裝置。Thus, an optical transmission device having a cylindrical member having an inner wall as a light reflecting surface and having an inner diameter of 15 cm and a length of 51 cm was produced.
(特性評價)(characteristic evaluation)
有關以實施例1~3及比較例1做成的光傳送裝置，係以第6(a)圖所示之方法來評價光傳送性能。With respect to the optical transmission apparatuses manufactured in Examples 1 to 3 and Comparative Example 1, the optical transmission performance was evaluated by the method shown in Fig. 6(a).
(光傳送性能)(optical transmission performance)
光傳送性能之評價係如第6(a)圖所示，藉由下述動作而進行，即，使用人工太陽照射燈20，以入射角60°而將光入射於各光傳送裝置18之一方，並於另一方之端面使用照度計19來測量照度。如第6(b)圖所示，照度係於中央部一處與周邊部四處，合計五處來加以測量。將評價結果顯示於表1。於表1中，有關照度，係顯示合計五處之測量值後之值。As shown in Fig. 6(a), the optical transmission performance is performed by using the artificial solar irradiation lamp 20 to inject light into one of the optical transmission devices 18 at an incident angle of 60°. The illuminance is measured using an illuminometer 19 on the other end face. As shown in Fig. 6(b), the illuminance is measured at one of the central part and the surrounding part, and is measured in five places. The evaluation results are shown in Table 1. In Table 1, the illuminance is the value after the total of five measurements.
如表1所示，實施例1~3之照度係大致與比較例1之照度相同。即，實施例1~3之光傳送裝置即便連結三個筒狀構件而加以製作，仍與使用沒有連結部之一個筒狀構件的比較例1為同程度的光傳送等級。又，有關剖面形狀之影響，由實施例1與實施例3之比較，照度係大致相同。因此，於光傳送性能上未見到差異。As shown in Table 1, the illuminances of Examples 1 to 3 were substantially the same as those of Comparative Example 1. In other words, the optical transmission apparatuses of the first to third embodiments were produced by connecting three cylindrical members, and the optical transmission level was the same as that of the comparative example 1 in which one cylindrical member having no connection portion was used. Further, the influence of the cross-sectional shape is substantially the same as that of the first embodiment and the third embodiment. Therefore, no difference was observed in the light transmission performance.
(第3實施形態)(Third embodiment)
其次，說明有關本發明第3實施形態之光傳送裝置之構成。Next, the configuration of the optical transmission device according to the third embodiment of the present invention will be described.
此實施形態之光傳送裝置與第1與第2實施形態不同之點，係在於採光部設置傾斜角度或傾斜方向不同的數個採光面。其他構成則與第1圖相同。The optical transmission device of this embodiment differs from the first and second embodiments in that the lighting unit is provided with a plurality of lighting surfaces having different inclination angles and oblique directions. The other configuration is the same as in the first figure.
(第1例)(1st example)
第7(a)、(b)圖係顯示有關本發明第3實施形態之第1例之採光部之圖。第7(a)圖為立體圖，第7(b)圖為沿著第7(a)圖之Ⅲ-Ⅲ線之剖面圖。7(a) and 7(b) are views showing a lighting unit according to a first example of the third embodiment of the present invention. Fig. 7(a) is a perspective view, and Fig. 7(b) is a cross-sectional view taken along line III-III of Fig. 7(a).
第1例之採光部21包含有二個採光面21a,21b，該等採光面都朝向南方，但傾斜角度不同。可依季節而分開使用。譬如由太陽高之春至夏，係以來自傾斜角度小之採光面21a的採光為主，太陽低之秋至冬，則以來自傾斜角度大之採 光面21b為主。圖中，標號22係構成光傳送裝置之筒狀構件。The lighting unit 21 of the first example includes two lighting surfaces 21a and 21b, all of which face south, but have different inclination angles. Can be used separately according to the season.
