特開平１０−２０８５０３号公報JP-A-10-208503

ところで、照度等の投光性能をコスト的に有利に高めることを目的として、上記のような、製品として完成された投光器のランプ笠内部に、新たに反射板を組み込むための技術的手段の開発を、本発明者らは進めている。 By the way, for the purpose of increasing the light projection performance such as illuminance in a cost-effective manner, the development of technical means for incorporating a new reflector inside the lamp shade of the projector completed as described above. The present inventors are proceeding.

しかしながら、ランプ笠の先端開口部は、既に前面ガラスが取外し困難に取り付けられていて閉塞されていることから、ガラス板を取り外し、反射板を、ランプ笠の先端開口部を通じてランプ笠の内部に組み込むということは、非常に難しい。 However, since the front opening of the lamp shade has already been closed because the front glass is difficult to remove, the glass plate is removed, and the reflector is incorporated into the lamp shade through the tip opening of the lamp shade. That is very difficult.

また、ランプ交換等のため、ランプ笠の基端部は開口していて、該基端開口部は、光源筒の先端部をランプ笠の基端部に接続することにより閉じられ、接続を解除することにより開かれるようになされているが、基端開口部の開口サイズは、反射板のサイズより小さく、そのため、反射板を、ランプ笠の基端開口部を通じてランプ笠の内部に組み込むということもできない。 In addition, the base end of the lamp shade is open for lamp replacement, etc., and the base end opening is closed by connecting the tip of the light source tube to the base end of the lamp shade and the connection is released. Although the opening size of the base end opening is smaller than the size of the reflector, the reflector is incorporated into the lamp shade through the base end opening of the lamp shade. I can't.

本発明は、上記のような問題点に鑑み、新たな反射板を投光器のランプ笠の内部に容易に組み込むことができて、照度等の投光性能をコスト的に有利に高めることができる、投光器への反射板の取付け方法を提供することを課題とする。 In view of the problems as described above, the present invention can easily incorporate a new reflector into the lamp shade of the projector, and can effectively increase the light projection performance such as illuminance. It is an object of the present invention to provide a method for attaching a reflector to a projector.

上記の課題は、先端部が前面ガラスで閉塞されると共に、基端部に開口を有し、かつ、内部の空間が基端開口部のがわから先端がわに向けて奥広がり状となっているランプ笠が備えられ、該ランプ笠の前記基端開口部が、光源筒の先端部をランプ笠の基端部に接続することにより閉じられ、接続を解除することにより開かれるようになされている投光器を対象とした反射板の取付け方法であって、
該反射板は、元サイズが前記ランプ笠の基端開口部の開口サイズよりも大きく、縮小可能であり、縮小することによりランプ笠の基端開口部を通じてランプ笠の内部に挿入配置することができるようになされたものからなっていて、
該反射板を用い、光源筒とランプ笠との接続を解除してランプ笠の基端開口部を開いた後、縮小状態の反射板をランプ笠の基端開口部を通じて内部空間に挿入し、しかる後、該反射板を元サイズに戻してランプ笠内の所定の位置に配置することを特徴とする投光器への反射板の取付け方法によって解決される（第１発明）。 The above problem is that the front end portion is blocked by the front glass, the base end portion has an opening, and the internal space is widened from the base end opening portion toward the front end toward the front end. A lamp shade is provided, and the base end opening of the lamp shade is closed by connecting the distal end of the light source tube to the base end of the lamp shade and opened by releasing the connection. A reflector mounting method for a projector that is,
The reflector has an original size larger than the opening size of the base end opening of the lamp shade and can be reduced, and can be inserted into the lamp shade through the base end opening of the lamp shade by being reduced. It was made up of things that were made possible
After opening the base end opening of the lamp shade by releasing the connection between the light source tube and the lamp shade using the reflector, the reduced reflector is inserted into the internal space through the base end opening of the lamp shade, Thereafter, the problem is solved by a method of attaching the reflector to the projector, wherein the reflector is returned to its original size and disposed at a predetermined position in the lamp shade (first invention).

この方法では、反射板は、元サイズがランプ笠の基端開口部の開口サイズよりも大きいが、縮小することが可能であり、縮小することによりランプ笠の基端開口部を通じてランプ笠の内部に挿入配置することができるようになされたものからなっていて、そのような反射板を用い、光源筒とランプ笠との接続を解除してランプ笠の基端開口部を開いた後、縮小状態の反射板をランプ笠の基端開口部を通じて内部空間に挿入し、しかる後、該反射板を元サイズに戻してランプ笠内の所定の位置に配置するものであるから、新たな反射板を、前面ガラスを取り外すことなく、投光器のランプ笠の内部に容易に組み込むことができて、照度等の投光性能をコスト的に有利に高めることができる。 In this method, the reflector has an original size larger than the opening size of the base end opening of the lamp shade, but can be reduced, and by reducing the size, the inside of the lamp shade is passed through the base end opening of the lamp shade. After using the reflector to release the connection between the light source tube and the lamp shade and opening the base end opening of the lamp shade, the size is reduced. The reflector in the state is inserted into the inner space through the base end opening of the lamp shade, and then the reflector is returned to its original size and arranged at a predetermined position in the lamp shade. Can be easily incorporated into the lamp shade of the projector without removing the front glass, and the light projection performance such as illuminance can be advantageously improved in terms of cost.

第１発明において、前記反射板は、反射板本体材と、形状保持材とを構成部品として備え、
反射板本体は、周方向において多角形であると共に基端がわから先端がわに向けて直線状に開いていく多角の角錐筒状をしていて、前記ランプ笠の基端開口部の開口サイズよりもサイズが大きく、面と面との境界部である屈折稜線部を軸として面と面を相対的に回動させることができるようになされており、回動させることによりサイズを縮小させることができるようになされており、縮小することによりランプ笠の基端開口部を通じてランプ笠の内部に挿入することができるようになされているものからなっていて、
前記形状保持材は、元サイズ状態の前記反射板本体の基端部に係合状態に取り付けられるリング状板からなっていて、反射板本体の基端部に係合状態に取り付けられることにより、反射板本体における隣り合う面部間の各屈折角度を所定の特定角度に保持して反射板本体を縮小前の元サイズ、元形状に保持するようになされたものからなっており、
縮小状態の前記反射板本体をランプ笠の基端開口部を通じて内部空間に挿入し、そこで反射板本体を元サイズ、元形状に戻した後、該反射板本体の基端部に前記形状保持材を係合状態に取り付けることで、元サイズ、元形状に保持された反射板本体を形成するとよい（第２発明）。 1st invention WHEREIN: The said reflecting plate is equipped with a reflecting plate main body material and a shape maintenance material as a component,
The reflector body is polygonal in the circumferential direction and has a polygonal pyramid shape that opens straight from the base end toward the end, and the opening size of the base end opening of the lamp shade The size is larger than the surface, and the surface and the surface can be rotated relative to each other about the refracting ridge line, which is the boundary between the surfaces, and the size can be reduced by rotating the surface. It is made to be able to be inserted into the inside of the lamp shade through the proximal end opening of the lamp shade by being reduced,
The shape holding material is composed of a ring-shaped plate that is attached to the base end portion of the reflector main body in the original size state, and is attached to the base end portion of the reflector main body. Each refraction angle between adjacent surface portions in the reflector main body is held at a predetermined specific angle, and the reflector main body is made to hold the original size before reduction, the original shape,
The reflector body in the reduced state is inserted into the internal space through the base end opening of the lamp shade, and after the reflector body is returned to its original size and shape, the shape retaining material is attached to the base end of the reflector body. It is good to form the reflector main body hold | maintained at the original size and the original shape by attaching to an engagement state (2nd invention).

この方法では、反射板を構成する反射板本体が、周方向において多角形であると共に基端がわから先端がわに向けて直線状に開いていく多角の角錐筒状をしていることにより、照度等の投光性能を非常に高いものにすることができる。 In this method, the reflector main body constituting the reflector has a polygonal pyramid shape that is polygonal in the circumferential direction and has a base end that opens linearly from the end toward the end. Light projection performance such as illuminance can be made extremely high.

しかも、反射板本体は、ランプ笠の基端開口部の開口サイズよりもサイズが大きいが、面と面との境界部である屈折稜線部を軸として面と面を相対的に回動させることができるようになされていると共に、回動させてサイズを縮小させることにより、ランプ笠の基端開口部を通じてランプ笠の内部に挿入することができるようになされていて、縮小状態の反射板本体をランプ笠の基端開口部を通じて内部空間に挿入するようにしているので、反射板本体をその元サイズにかかわらず、ランプ笠の内部に容易に組み込むことができるのはもちろん、
サイズ縮小のための回動は、多角の角錐筒状の形状における面と面との境界部である屈折稜線部を軸として行われるものであるから、縮小、復元のためにそのような回動を反射板本体に行わせても投光性能が損なわれることはない。 Moreover, the reflector body is larger in size than the opening size of the base end opening of the lamp shade, but the surface and the surface are relatively rotated around the refracting ridge line portion that is the boundary between the surface and the surface. The reflector body in a reduced state can be inserted into the inside of the lamp shade through the base end opening of the lamp shade by rotating and reducing the size. Is inserted into the inner space through the base end opening of the lamp shade, so that the reflector body can be easily incorporated into the lamp shade regardless of its original size.
Since the rotation for size reduction is performed with the refracting ridge line portion, which is the boundary between the surfaces in the polygonal pyramid shape, as the axis, such rotation for reduction and restoration is performed. Even if the reflector body is used, the light projecting performance is not impaired.

そして、反射板本体の構成要素として、更に、形状保持材を備え、該形状保持材は、リング状板からなっていて、ランプ笠の内部空間に挿入しそこで元サイズ、元形状に戻した反射板本体の基端部に係合状態に取り付けることで、元サイズ、元形状に保持された反射板本体を形成するようにしているので、上記のように縮小変形可能であると言いながら、元形状に戻せば、形状保持材によって、元サイズ、元形状をしっかりと保つことができて、組込み後における反射板本体の投光性能を高いものに保つことができる。 Further, as a component of the reflector main body, a shape-retaining material is further provided, and the shape-retaining material is a ring-shaped plate, and is inserted into the inner space of the lamp shade, and is then returned to its original size and shape. By attaching to the base end of the plate body in an engaged state, the reflector plate body held in the original size and shape is formed, so it can be reduced and deformed as described above. If it returns to a shape, the original size and the original shape can be firmly maintained by the shape-retaining material, and the light projecting performance of the reflector main body after incorporation can be kept high.

第２発明において、前記反射板が、前記形状保持材を挟んで前記反射板本体とは反対側の基端がわに備えられる基端がわ反射板本体を備え、
該基端がわ反射板本体の先端部に前記形状保持材が予め取り付けられたものを用い、
縮小状態の先端がわ反射板本体をランプ笠の基端開口部を通じて内部空間に挿入し、そこで該先端がわ反射板本体を元サイズ、元形状に戻した後、該先端がわ反射板本体の基端部に、前記基端がわ反射板本体付きの形状保持材を係合状態に取り付けて、元サイズ、元形状に保持された先端がわ反射板本体を形成するとよい（第３発明）。 In the second invention, the base plate provided with a base end opposite to the main body of the reflector opposite to the main body of the reflector with the shape holding member interposed therebetween,
The base end is used in which the shape retaining material is attached in advance to the distal end portion of the reflector main body,
The reduced-end tip reflector body is inserted into the internal space through the base end opening of the lamp shade, and after returning the tip reflector body to its original size and shape, the tip is attached to the reflector body. It is preferable that the base end portion of the base plate is attached with the shape holding member with the base end of the reflector plate body in an engaged state, and the tip end held in the original size and shape is formed as a base member of the base plate (third invention). ).

この場合は、反射板が、先端がわ反射板本体に加え、更に、基端がわ反射板本体を備えたものであるから、照度等の投光性能をより一層高いものにすることができる。 In this case, since the reflecting plate is provided with the leading edge reflecting plate body in addition to the leading edge reflecting plate body, the light projecting performance such as illuminance can be further enhanced. .

しかも、該基端がわ反射板本体の先端部に前記形状保持材が予め取り付けられたものを用い、縮小状態の先端がわ反射板本体をランプ笠の基端開口部を通じて内部空間に挿入し、そこで該先端がわ反射板本体を元サイズ、元形状に戻した後、該先端がわ反射板本体の基端部に、前記基端がわ反射板本体付きの形状保持材を係合状態に取り付けて、元サイズ、元形状に保持された先端がわ反射板本体を形成するようにしているので、ランプ笠内の元サイズ、元形状に戻した先端がわ反射板本体の基端部に対する形状保持材の取付けを、先端がわ反射板本体を手で操作しながら行うことができて、先端がわ反射板本体基端部への形状保持材の取付けを容易にすることができる。 In addition, the base end is used in which the shape-retaining material is previously attached to the distal end portion of the reflector body, and the reduced distal end is inserted into the internal space through the proximal end opening of the lamp shade. Therefore, after the tip of the wrinkle reflector main body is returned to the original size and shape, the tip end is engaged with the base end portion of the wrinkle reflector main body with the shape holding material with the base reflector. Because the tip that is held in the original size and shape is attached to the base, it forms the wrinkle reflector body. The shape holding member can be attached to the base plate while the tip end reflector body is manually operated, and the tip holding member can be easily attached to the base end portion of the tip reflector portion.

本発明の、投光器への反射板の取付け方法は、以上のとおりのものであるから、新たな反射板を投光器のランプ笠の内部に容易に組み込むことができて、照度等の投光性能をコスト的に有利に高めることができる。 Since the method of attaching the reflector to the projector according to the present invention is as described above, a new reflector can be easily incorporated into the lamp shade of the projector, and the projection performance such as illuminance can be improved. The cost can be advantageously increased.

次に、本発明の実施形態を図面に基づいて説明する。 Next, embodiments of the present invention will be described with reference to the drawings.

図１〜図５に示す実施形態の、投光器への反射板の取付け方法において、１が、製品として完成された投光器、２が新たな反射板である。 In the embodiment shown in FIG. 1 to FIG. 5, 1 is a projector that is completed as a product, and 2 is a new reflector.

投光器１は、図１（イ）、図４及び図５に示すように、光源筒３と、ランプ笠４とを備えている。ランプ笠４は、先端部が前面ガラス５で閉塞されていると共に、基端部に開口４ａを有し、かつ、内部の空間４ｂが基端開口部４ａのがわから先端がわに向けて奥広がり状となっている。 The projector 1 includes a light source tube 3 and a lamp shade 4 as shown in FIGS. The lamp shade 4 is closed at the front end portion by the front glass 5 and has an opening 4a at the base end portion, and the inner space 4b extends from the side of the base end opening portion 4a toward the tip side. It is spread.

光源筒３は、ランプ６を接続するソケット７を備えたもので、ランプ笠４とは周方向における一カ所において枢結されており、ランプ笠４の基端開口部４ａは、該枢結部８を軸として光源筒３を回動させて光源筒３の先端部をランプ笠４の基端部に接続することにより閉じられ、光源筒３を逆方向に回動させて接続を解除することにより開かれるようになされている。 The light source tube 3 is provided with a socket 7 for connecting a lamp 6, and is pivotally connected to the lamp shade 4 at one place in the circumferential direction, and the proximal end opening 4 a of the lamp shade 4 is connected to the pivot portion. The light source tube 3 is rotated about the axis 8 and closed by connecting the distal end portion of the light source tube 3 to the base end portion of the lamp shade 4, and the connection is released by rotating the light source tube 3 in the reverse direction. It is made to be opened by.

そして、反射板２は、図１（ロ）に示すように、先端がわ反射板本体９と、形状保持材１０と、基端がわ反射板本体１１とを、構成部品として備えている。 As shown in FIG. 1 (b), the reflecting plate 2 includes a tip reflecting plate main body 9, a shape holding material 10, and a base end reflecting plate main body 11 as components.

先端がわ反射板本体９は、図２（イ−１）（イ−２）に示すように、周方向において多角形であると共に、基端がわから先端がわに向けて直線状に開いていく多角、具体的には例えば１６角の角錐筒状の多面体からなっていて、図１（イ）に示すように、ランプ笠４の基端開口部４ａの開口サイズよりもサイズが大きい。そして、該先端がわ反射板本体９は、図３（イ）（ロ）に示すように、面９ａと面９ａとの境界部である屈折稜線部９ｂを軸として面９ａと面９ａを相対的に回動させることができるようになされており、回動させることによりサイズを縮小させることができるようになされており、図３（ハ）、図４（ハ）（ニ）に示すように、縮小することによりランプ笠４の基端開口部４ａを通じてランプ笠４の内部に挿入することができるようになされている。 As shown in FIGS. 2 (A-1) and (A-2), the distal end reflection plate main body 9 is polygonal in the circumferential direction, and the base end is opened linearly from the end toward the end. It consists of a polyhedron, specifically, a 16-sided pyramid-shaped polyhedron, and is larger than the opening size of the base end opening 4a of the lamp shade 4 as shown in FIG. Then, as shown in FIGS. 3 (A) and 3 (B), the leading edge reflector main body 9 has the surface 9a and the surface 9a relative to each other with the refracting ridge line portion 9b as the boundary between the surface 9a and the surface 9a as an axis. 3 (c), 4 (c) and 4 (d) as shown in FIGS. 3 (c), 4 (c) and 4 (d). By being reduced in size, it can be inserted into the lamp shade 4 through the base end opening 4a of the lamp shade 4.

屈折稜線部９ｂを軸として面９ａと面９ａを相対的に回動させることができるようにするため、一方の面をもう一方の面に被らせるようにしてこれら面と面とを蝶番でつないだり、あるいは、面と面との間にスリットを入れると共にスリットを入れた部分に金属硬化による破断を防ぐテープ補強をすることなど、種々の構造が採られてよい。 In order to allow the surface 9a and the surface 9a to be rotated relative to each other with the refracting ridge line portion 9b as an axis, the surface and the surface are hinged so that one surface is covered with the other surface. Various structures may be employed, such as connecting them, or inserting a slit between the surfaces and reinforcing the slits with tape to prevent breakage due to metal hardening.

形状保持材１０は、図１（ロ）、図２（ロ−１）（ロ−２）に示すように、元サイズ状態の先端がわ反射板本体９の基端部に係合状態に取り付けられるリング状板からなっていて、先端がわ反射板本体９の基端部に係合状態に取り付けることにより、先端がわ反射板本体９における隣り合う面部９ａ，９ａ間の各屈折角度を所定の特定角度、本実施形態では正１６角形における辺と辺のなす角度に保持して、先端がわ反射板本体９を縮小前の元サイズ、元形状に保持するものである。 As shown in FIG. 1 (B), FIG. 2 (B-1) and (B-2), the shape retaining material 10 is attached to the base end of the wrinkle reflector main body 9 in an engaged state. Each of the refraction angles between the adjacent surface portions 9a, 9a of the reflective reflector main body 9 is determined by attaching the distal end of the reflective reflector main body 9 to the base end of the reflective reflector main body 9 in an engaged state. Is held at the angle formed by the sides of the regular hexagon in this embodiment, and the leading edge reflector main body 9 is held at the original size and shape before reduction.

基端がわ反射板本体１１は、形状保持材１０を挟んで、先端がわ反射板本体９とは反対側の、基端がわに備えられる反射板本体で、先端がわ反射板本体９と同じく、周方向において多角形であると共に、基端がわから先端がわに向けて直線状に開いていく多角、具体的には例えば１６角の角錐筒状の多面体からなっている。なお、本実施形態では、基端がわ反射板本体１１は、ランプ笠４の基端開口部４ａの開口サイズよりもサイズが小さく、そのため、先端がわ反射板本体９の場合のような縮小機能は、備えられていてもよいし、備えられていなくてもよい。 The proximal end reflector body 11 is a reflector body provided on the opposite side of the distal end reflector body 9 with the shape holding material 10 interposed therebetween, and the distal end reflector body 9 is provided on the proximal end. Similarly, it is a polygon in the circumferential direction and has a polygon whose base end is linearly opened from the end toward the end, specifically, for example, a 16-sided pyramidal polyhedron. In the present embodiment, the base end reflector body 11 is smaller in size than the opening size of the base end opening 4a of the lamp shade 4, so that the tip is reduced as in the case of the base reflector body 9. The function may be provided or may not be provided.

そして、該基端がわ反射板本体１１は、投光器への組込み取付けに際して、図５（ヘ）に示すように、予め、その先端を、形状保持材１０に取り付けて、形状保持材１０と一体化させておく。 When the base end reflector body 11 is assembled and mounted to the projector, as shown in FIG. 5 (f), the tip is attached to the shape holding member 10 in advance and integrated with the shape holding member 10. I will make it.

形状保持材１０に対する基端がわ反射板本体１１の取付け、及び、先端がわ反射板本体９に対する形状保持材１０の取付けのため、本実施形態では次のような構造が採用されている。即ち、図２（イ−１）（イ−２）に示すように、先端がわ反射板本体９の基端部には、形状保持材１０を構成するリング状板の板面に沿うことのできる複数の内向き張出し板部９ｃ…が周方向に間隔的に設けられると共に、各内向き張出し板部９ｃに通孔９ｄが設けられている。また、図２（ハ−１）（ハ−２）に示すように、基端がわ反射板本体１１の先端部にも、形状保持材１０の板面に沿うことのできる複数の外向き張出し板部１１ｃ…が周方向に間隔的に設けられると共に、各外向き張出し板部１１ｃに通孔１１ｄが設けられている。そして、図２（ロ−１）に示すように、形状保持材１０には、先端がわ反射板本体９がわの通孔９ｄ…と、基端がわ反射板本体１１がわの通孔１１ｄ…とに対応する多数の通孔１０ｄ…が、周方向間隔的に設けられている。 In order to attach the base end reflecting plate main body 11 to the shape holding member 10 and to attach the shape holding member 10 to the tip end reflecting plate main body 9, the following structure is adopted in this embodiment. That is, as shown in FIGS. 2 (A-1) and (A-2), the distal end of the base plate portion of the reflector plate main body 9 is along the plate surface of the ring-shaped plate constituting the shape holding material 10. A plurality of inward extending plate portions 9c... That can be formed are provided at intervals in the circumferential direction, and through holes 9d are provided in each inward extending plate portion 9c. Further, as shown in FIGS. 2 (C-1) and (C-2), a plurality of outward projections whose base ends can also extend along the plate surface of the shape-retaining material 10 at the distal end portion of the reflector main body 11 as well. Plate portions 11c are provided at intervals in the circumferential direction, and through holes 11d are provided in each outwardly extending plate portion 11c. As shown in FIG. 2 (B-1), the shape-retaining material 10 has a leading edge reflecting plate body 9 having a through hole 9d, and a base end reflecting plate body 11 having a through hole. A plurality of through holes 10d corresponding to 11d are provided at intervals in the circumferential direction.

それにより、形状保持材１０に対する基端がわ反射板本体１１の取付けは、基端がわ反射板本体１１の先端の各外向き張出し板部１１ｃを、通孔１１ｄ，１０ｄを一致させるように、形状保持材１０の板面に沿わせ、ビス又はボルトを通して締結するというようにして行うことができるようになされている。また、形状保持材１０に対する先端がわ反射板本体９の取付けは、先端がわ反射板本体９の基端の各内向き張出し板部９ｃを、基端がわ反射板本体１１の外向き張出し部１１ｃとは周方向に位相を異ならせて通孔９ｄ，１０ｄを一致させるように、形状保持材１０の板面に沿わせ、ビス又はボルトを通して締結するというようにして行うことができるようになされている。 Thereby, the base end reflector plate main body 11 is attached to the shape maintaining material 10 so that the outwardly extending plate portions 11c at the tip end of the base end reflector main body 11 are aligned with the through holes 11d and 10d. It can be carried out by following the plate surface of the shape-retaining material 10 and fastening with screws or bolts. In addition, the distal end reflector plate body 9 is attached to the shape retaining member 10 by extending the inwardly projecting plate portions 9c at the proximal end of the distal end reflector body 9 to the outwardly extending base plate reflector 11 from the proximal end. It is possible to carry out such that the phase is different from that of the portion 11c in the circumferential direction so that the through holes 9d and 10d coincide with each other along the plate surface of the shape-retaining material 10 and tightened through screws or bolts. Has been made.

なお、ビス又はボルトに代えてリベットで取り付けるようにしてもよいし、また、図２（ロ−３）に示すように、形状保持材１０に、先端がわ反射板本体９の取付けのために設けられる通孔をスリット孔１０ｅに代え、先端がわ反射板本体９の基端部の張出し板部９ｃを貫通状態に差し込んで、内向きに屈曲させて取り付ける構成などが採用されてもよく、種々の取付け構造が採用されてよい。 In addition, you may make it attach with a rivet instead of a screw | thread or a volt | bolt, and as shown in FIG. Instead of the through hole provided in place of the slit hole 10e, a configuration in which the protruding plate portion 9c of the base end portion of the reflective reflector main body 9 is inserted into a penetrating state and bent inwardly may be adopted. Various attachment structures may be employed.

投光器１への反射板２の取付けは、まず、図４（イ）（ロ）に示すように、投光器１を、ランプ笠４の先端部を下にするようにして置き、図示しないロックを解除して光源筒３を回動させ、光源筒３とランプ笠４との接続を解除し、ランプ笠４の基端開口部４ａを開く。次いで、図４（ハ）（ニ）に示すように、縮小状態にした先端がわ反射板本体９を、ランプ笠４の基端開口部４ａを通じてランプ笠４の内部空間に挿入し、そこで、図５（ホ）に示すように、先端がわ反射板本体９を元サイズ、元形状に戻す。戻すのは、手をランプ笠４の基端開口部４ａを通じてランプ笠４の内部空間に入れて行うようにすればよい。サイズの縮小や復元のための回動は、多角の角錐筒状の形状における面９ａと面９ａとの境界部である屈折稜線部９ｂを軸として行われるから、縮小、復元のためにそのような回動を先端がわ反射板本体９に行わせても投光性能が損なわれることはない。また、先端がわ反射板本体９は、元形状に戻せば、形状保持材１０によって、元サイズ、元形状をしっかりと保つことができて、組込み後における先端がわ反射板本体９の投光性能を高いものに保つことができる。 To attach the reflector 2 to the projector 1, first place the projector 1 with the tip of the lamp shade 4 facing down as shown in FIGS. Then, the light source tube 3 is rotated, the connection between the light source tube 3 and the lamp shade 4 is released, and the base end opening 4a of the lamp shade 4 is opened. Next, as shown in FIGS. 4 (a) and 4 (d), the reduced leading edge reflector main body 9 is inserted into the interior space of the lamp shade 4 through the proximal end opening 4a of the lamp shade 4, As shown in FIG. 5 (e), the leading edge reflector main body 9 is returned to its original size and shape. The return may be performed by putting the hand into the internal space of the lamp shade 4 through the proximal end opening 4 a of the lamp shade 4. The rotation for reducing or restoring the size is performed with the refracting ridge line portion 9b, which is the boundary between the surface 9a and the surface 9a, in the polygonal pyramid-like shape as an axis. Even if the tip is made to rotate the tip of the reflector main body 9, the light projecting performance is not impaired. In addition, if the leading edge reflector main body 9 is returned to its original shape, the original size and original shape can be firmly maintained by the shape-retaining material 10, and the leading edge reflecting plate body 9 can be projected after being assembled. High performance can be maintained.

しかる後、図５（ヘ）（ト）に示すように、予め、基端がわ反射板本体１１が取り付けられている、基端がわ反射板本体１１付きの形状保持材１０を用い、先端がわ反射板本体９の基端部に、基端がわ反射板本体１１付きの形状保持材１０をビス又はボルトで係合状態に取り付けて、元サイズ、元形状に保持された先端がわ反射板本体９を形成する。予め、基端がわ反射板本体１１が取り付けられている形状保持材１０を用いるから、ランプ笠４内の元サイズ、元形状に戻した先端がわ反射板本体９の基端部に対する形状保持材１０の取付けを、基端がわ反射板本体１１を手で操作しながら行うことができて、先端がわ反射板本体９の基端部への形状保持材１０の取付けを容易にすることができる。 Thereafter, as shown in FIGS. 5F and 5G, the shape holding member 10 with the base end reflecting plate main body 11 attached to the base end in advance is used, and the tip end is used. A shape holding material 10 with a base end reflector plate body 11 is attached to the base end portion of the base plate reflector 9 in an engaged state with screws or bolts, and the tip held in the original size and shape is fixed. The reflector main body 9 is formed. Since the shape-retaining material 10 to which the base end reflector body 11 is attached in advance is used, the original size in the lamp shade 4 and the tip returned to the original shape retain the shape with respect to the base end portion of the base part 9. The material 10 can be attached while the base end reflector body 11 is operated by hand, and the front end of the shape reflector 10 is easily attached to the base end part of the base plate 9. Can do.

最後に、図５（チ）に示すように、光源筒３を回動させて、光源筒３の先端部をランプ笠４の基端部に接続し、ランプ笠４の基端開口部を閉じる。なお、その際に、光源筒３のソケット７に接続しているランプ６が基端がわ反射板本体１１と干渉するような場合は、図示しないが、基端がわ反射板本体１１にランプ６を避ける切欠きを設けておくようにするとよい。以上のようして、投光器１に反射板２を組み込むことができる。 Finally, as shown in FIG. 5 (h), the light source tube 3 is rotated to connect the distal end portion of the light source tube 3 to the proximal end portion of the lamp shade 4, and the proximal end opening of the lamp shade 4 is closed. . In this case, if the lamp 6 connected to the socket 7 of the light source tube 3 interferes with the base plate 11 at the base end, although not shown, the base end is connected to the base plate 11 at the base end. It is advisable to provide a notch that avoids 6. As described above, the reflector 2 can be incorporated into the projector 1.

このように、上記の方法によれば、新たな反射板２を、ランプ笠４の前面ガラス５を取り外すことなく、投光器１のランプ笠４の内部に容易に組み込むことができて、照度等の投光性能をコスト的に有利に高めることができる。 As described above, according to the above method, the new reflector 2 can be easily incorporated into the lamp shade 4 of the projector 1 without removing the front glass 5 of the lamp shade 4. The light projection performance can be advantageously increased in terms of cost.
