Abstract

Beleuchtungsvorrichtung, bestehend aus einer stabförmigen Lichtquelle (1) von einer bestimmten Länge, einem als Zylinder­ abschnitt ausgebildeter Reflektor (2), der zur stabförmigen Lichtquelle einen Abstand aufweist, der gleich oder kleiner ist als der Radius des Zylinders, einer zentrisch zur Mit­ telachse (x) in einem Abstand von der stabförmigen Lichtquelle und dem Reflektor angeordnete Linse (3). Dabei ist vorzugsweise in einem Radius zur Längsachse der stabförmigen Lichtquelle zwischen dieser und der Linse eine als Zylinderabschnitt ausgebildete Lichtblende (4) und ferner die stabförmige Licht­ quelle mit ihrer Längsachse (y) waagrecht und rechtwinklig zur Mittelachse (x) angeordnet. Lighting device consisting of a rod-shaped Light source (1) of a certain length, one as a cylinder section trained reflector (2), which is for rod-shaped Light source has a distance that is equal to or less is the radius of the cylinder, one centered on the center telachse (x) at a distance from the rod-shaped light source and the lens (3) arranged on the reflector. It is preferred in a radius to the longitudinal axis of the rod-shaped light source between this and the lens one as a cylinder section trained light diaphragm (4) and also the rod-shaped light source with its longitudinal axis (y) horizontal and perpendicular to Center axis (x) arranged.
