Description
【考案の詳細な説明】 この考案は集光型スポットライトに関するものである。[Detailed explanation of the idea] This invention relates to a condensing spotlight.
従来例を第１図ないし第３図に示している。Conventional examples are shown in FIGS. 1 to 3.
すなわち、この補集光型スポットライトは、フランジ１

する。In other words, this supplementary light type spotlight has flange 1
is attached to the ceiling or wall, a rotary shaft 2 is rotatably attached to the flange 1, one end of the arm 3 is rotatably attached to the rotary shaft 2, and a shade 4, which becomes the main body of the device, is rotatably attached to the other end of the arm 3. As shown in FIGS. 2 and 3, the lamp socket 5 is attached to the inner bottom of the shade 4, and the pin 7 of the micro halogen lamp 6 is inserted into the lamp socket 5. The opening edge of the parabolic reflector plate 8 is aligned with the opening edge of the parabolic reflector plate 8, and the rubber ring 9 is attached to the reflector plate so that the filament 6a of the lamp 6 is positioned at the focal point of the rubber ring 9.
１０はキャップである。ところが、この集光型スポット

置がずれてランプフィラメントが反射板の焦点位置に合
わないという欠点があった。10 is a cap. However, in this condensing spotlight, as shown in FIG.
Since this was determined by inserting the filament into the socket 5 and the bottom surface of the glass part 6b coming into contact with the surface of the socket 5, the position of the filament 6a (dimension l from the shade 4) varies due to variations in the glass thickness that occur during glass molding. In addition, due to dimensional variations in the shade itself, the focal position of the reflector 8 is shifted and the lamp filament is not aligned with the focal position of the reflector.
したがって、この考案の目的は、ランプ光源点と反射体
の焦点とを簡単かつ精度良く合わすことができる集光型
スポットライトを提供することである。Therefore, an object of this invention is to provide a condensing spotlight that can easily and precisely align the lamp light source point and the focus of the reflector.
この考案の一実施例を第４図および第５図に示す。An embodiment of this invention is shown in FIGS. 4 and 5.
すなわち、この集光型スポットライトは、ランプピン１
１を長く延出してランプソケット５に最大量差し込むと
ともにガラス６ｂの底面がソケット表面に当接しないよ
うにし、そのランプピン１１の長さを一定にする。In other words, this condensing spotlight has lamp pin 1
The length of the lamp pin 11 is made constant by extending the length of the lamp pin 11 and inserting it into the lamp socket 5 by the maximum amount, and by preventing the bottom surface of the glass 6b from coming into contact with the socket surface.
またセード１２の内底面に反射板台１３を取付け、反射
板台１３に反射体１４を取付けてセード１２の開口縁は
フリーになるようにする。Further, a reflection plate stand 13 is attached to the inner bottom surface of the shade 12, and a reflector 14 is attached to the reflection plate stand 13, so that the opening edge of the shade 12 is made free.
その他の構成は第１図ないし第３図のものと同様である
。The other configurations are the same as those in FIGS. 1 to 3.
このように構成し７たため、ランプフィラメント６ａの
位置決めは採寸されたランプピンの長さによって決定さ
れ、この長さおよびソケット５の最大差し込み量のばら
つきはガラス成形による肉厚のばらつきと比較して皆無
に近い程少なく、また反射板１４は反射板台１３に取付
けられるのでセード１２と比較して寸法ばらつきは小さ
く、よつてランプフィラメント６ａを反射体の焦点に精
度良く簡単に合致できることとなる。With this configuration 7, the positioning of the lamp filament 6a is determined by the measured length of the lamp pin, and the variation in this length and the maximum insertion amount of the socket 5 is negligible compared to the variation in wall thickness due to glass molding. Moreover, since the reflector plate 14 is attached to the reflector stand 13, the dimensional variation is smaller than that of the shade 12, so that the lamp filament 6a can be easily aligned with the focal point of the reflector with high accuracy.
以上のように、この考案の集光型スポットライトは、ラ
ンプをランプピンによりランプソケットに挿着してガラ
ス部がソケットに接触しないようにするとともに反射体
のランプ挿入用開口の縁部を反射板台に取り付けるよう
にしたため、ランプの交換ができるとともに反射体を変
形することがなく安価にでき、しかも反射体の焦点に対
してランプの発光点をばらつきなく正確に位置決めてき
るという効果を有する。As described above, in the condensing spotlight of this invention, the lamp is inserted into the lamp socket with the lamp pin to prevent the glass part from touching the socket, and the edge of the lamp insertion opening of the reflector is connected to the reflector. Since the lamp is mounted on a stand, the lamp can be replaced, the reflector is not deformed and the cost is reduced, and the light emitting point of the lamp can be accurately positioned with no variation in relation to the focal point of the reflector.
