ラムの挿入させる。The illustrated illumination device with a framing function has a reflector 10 and a longitudinal layer filament L.
The housing 8 includes a housing 8 containing a light emitting source 9 constituted by 1 and 1. The inner surface of the reflector 10 forms a granite pattern, a rough, bubbly or prickly pattern, creating a scattered light beam. The fact of having a light source with an axial filament avoids the development of a central shadow. This housing has one or more slides or guides 12
including the insertion of a diaphragm formed by one or more plate members.

A plurality of apertures 14c are formed, each corresponding to a character.

直角でない角度をもつ対照物をフレームぎめさせる。The diaphragm shown in FIG.
It consists of plate members 16 which, once inserted into the corresponding guides 12 of the housing 8, form a polygonal opening 14 (square in this example) between the plate members. The shape and dimensions of this opening 14 can be deformed by sliding or moving one or several plate members 13 in the radial direction (arrow I), and further between the guide 12 and the plate member 16. By providing one play, these plate members are also moved slightly rotationally (arrow...), thereby modifying the final central non-illuminated part of the light source or contrast with non-perpendicular angles. Frame things.
本発明の重要点は、ダイヤフラムを発光源の極く近ぐに
配置したこと、及びこれら二つの要素間には光学的要素
を挿入していないことである。従ってこのダイヤフラム
は発光源？、１０．１１によって発せられた発光光線を
直接に制限する。The key point of the invention is that the diaphragm is placed very close to the light source and that no optical element is inserted between these two elements. Therefore, is this diaphragm the source of light? , 10.11.
さらに、ハウ・ランプ８の前方部分には焦点合わせ可能
なレンズ１６を具備する滑動式対物レンズ１５が配設さ
れる。Furthermore, a sliding objective 15 with a focussable lens 16 is arranged in the front part of the Howe lamp 8 .

無くすことによって、このような照明装置の発光効率は
同一出力に対し現用の装置の効率よりも３０〜８０％高
い。さらに、コンデンサを無くすことは、装置の全体的
な障害、特にその価格と同様にその長さを減する。As can be seen from the figure, the luminescence of such a lighting device can be improved by using lamps with granite pattern, textured or stylus reflector and axial filament, i.e. by eliminating the capacitor. The efficiency is 30-80% higher than that of current equipment for the same power output. Furthermore, eliminating the capacitor reduces the overall complexity of the device, especially its length as well as its price.

効率を増大する。This is of no concern since to date it has been shown that it has not been possible to obtain precise and focused framing capabilities to directly limit the light rays emitted from the light source. <There is one thing to do. However, this is not only possible but also reduces cost and bottlenecks and increases the efficiency of the device.
