Abstract

Bei einer Taschenleuchte (1) mit einer Halogenglüh­ lampe (11) besteht das Reflektor- und Linsensystem aus ei­ nem elliptischen Reflektorteil (12), das in Ausstrahlungs­ richtung mit einem kugelzonenförmigen Reflektorteil (13), dessen grössere Öffnung zum elliptischen Reflektorteil (12) hinzeigt, fest verbunden ist. Ausserdem beinhaltet das Sy­ stem eine asphärische Sammellinse (16), die in einem ge­ wissen Abstand - in Ausstrahlungsrichtung - vor dem Re­ flektor (12, 13) angebracht ist. Zwischen dem kugelzonen­ förmigen Reflektorteil (13) und der asphärischen Sammel­ linse (16) ist zusätzlich entweder fest eine Lochblende (14) mit variabler Blendenöffnung (15) oder längs der optischen Achse verschiebbar eine Lochblende mit fester Blendenöff­ nung angebracht. Mit Hilfe des Reflektor- und Linsensy­ stems sowie der Blende lassen sich mit der Taschenleuchte Lichtkegel mit variablem Öffnungswinkel erzeugen, wobei die beleuchteten Bildflächen eine sehr helle und völlig gleichmässige Ausleuchtung mit einer scharfen Begren­ zung aufweisen. With a flashlight (1) with a halogen glow lamp (11) the reflector and lens system consists of egg nem elliptical reflector part (12) which is in emission direction with a spherical zone-shaped reflector part (13), its larger opening to the elliptical reflector part (12) indicates is firmly connected. The Sy also includes stem an aspherical converging lens (16) in a ge know distance - in the direction of radiation - in front of the re flector (12, 13) is attached. Between the spherical zones shaped reflector part (13) and the aspherical collection lens (16) is either either a fixed aperture (14) with variable aperture (15) or along the optical A pinhole with a fixed aperture is displaceable on the axis attached. With the help of the reflector and lens system stems and the bezel can be adjusted with the flashlight Generate a cone of light with a variable opening angle, whereby the illuminated picture areas a very bright and complete uniform illumination with a sharp limit have tongue.
