Abstract

The reflector is for radiation generators, esp. for ultraviolet and infrared radiators having light sources with a slot shaped radiation outlet surface. The reflector is spiral shaped when viewed from the side and the radiation source is located inside the track of the centre of curvature of the reflector. The longitudinal extension of the reflector is made to correspond to that of the radiation source. The spiral shape of the reflector is a reproduction of a logarithmic spiral or alternatively of an amhimedic, hyperbolic or parabolic spiral.

Description

"Reflektor für Strahlenquellen" "Reflector for radiation sources"

Die Erfindung betrifft einen Reflektor für Strahlenquellen, insbesondere Ultraviolett-, Infrarot-Strahler, Lichtquellen und dergleichen, mit spt£örmiger Strahlenaustrittsfläche.The invention relates to a reflector for radiation sources, in particular Ultraviolet, infrared emitters, light sources and the like, with latex Beam exit surface.

Reflektoren bekannter Bauart für stabförmige oder ähnlich räumlich ausgedehnte Strahlenquellen reflektieren einen Teil der Strahlung auf die Strahlenquelle zurück, wodurch ihr Wirkungsgrad erheblich vermindert wird.Known design reflectors for rod-shaped or similar three-dimensional extensive radiation sources reflect part of the radiation onto the radiation source back, which significantly reduces their efficiency.

Es war zwar aus der deutschen Patentschrift 806 001 und der deutschen Patentschrift 808 701 bekannt, Reflektoren für ausgedehnte Lichtquellen so zu gestalten, daß der Reflektor Evolventenbögen folgt. Dabei mündete jedoch entweder die Spitze direkt auf dem Umfang der Lichtquelle oder beide Evolventenbögen stießen unter einem Winkel zusammen.It was from the German patent specification 806 001 and the German Patent 808 701 known to design reflectors for extended light sources so that the reflector follows involute arcs. However, either the tip ended here right on the perimeter of the light source or both involute arcs butted under one Angles together.

Aufgabe der Erfindung ist es, einen Reflektor für Strahlenquellen mit spaltförmigem Strahlenaustritt so auszubilden, daß die Strahlenquelle innerhalb der Bahn des Kr'urigsmittelpunktes der Krümmung des Reflektors liegt.The object of the invention is to provide a reflector for radiation sources with a gap-shaped beam exit so that the radiation source is within the path of the center of the curvature of the reflector lies.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß der Reflektor in der Seitenansicht spiralförmig ausgebildet ist und dann die Strahlenquelle innerhalb der Bahn des KrUrnrnungsmittelpunktes des Reflektors angeoranet ist sowie daß die Längsausdehnung des Reflektors derjenigen der Strahlenquelle angepaßt ist.This object is achieved according to the invention in that the reflector is formed spirally in the side view and then the radiation source within the path of the center of the curve of the reflector is anoranet and that the Longitudinal extension of the reflector is adapted to that of the radiation source.

Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further refinements of the invention are attached to the subclaims remove.

Die Erfindung hat gegenüber Reflektoren mit Evolventenbögen den Vorteil, daß die Spiralform keine Spitze aufweist, daher einfacher herstellbar ist und trotzdem die Eigenabschattung der Strahlenquelle vermieden wird und zugleich eine bessere Richtcharakteristik der reflektierten Strahlung erreicht wird.The invention has the advantage over reflectors with involute arcs, that the spiral shape has no point and is therefore easier to manufacture and yet the self-shadowing of the radiation source is avoided and at the same time a better one Directional characteristic of the reflected radiation is achieved.

Weiterhin bietet der erfinaungsgemäße Reflektor den Vorteil, daß die Strahlenquelle von außen völlig abgedeckt, also unzugänglich sein kann. Dadurch bietet er einen Berührungsschutz, wie ihn die Reflektoren mit Evolventenform nicht bieten können Verschiedene Ausführungsbeispiele der Erfindung sind in den beigefügten Zeichnungen rein schematisch dargestellt, ohne die Erfindung hierauf zu beschränken.Furthermore, the reflector according to the invention offers the advantage that the Radiation source completely covered from the outside, so it can be inaccessible. Through this it offers protection against accidental contact that the reflectors with involute shape do not Various embodiments of the invention are set out in the accompanying drawings Drawings are shown purely schematically, without restricting the invention thereto.

Es zeigen: Figur 1 die Seitenansicht eines Reflektors mit logarithmischer Spiralform, Figur 2 die Seitenansicht eines Reflektors mit einer Spiralform, die einer Exponentialfunktion folgt, Figur 3 die Seitenansicht eines Reflektors mit parabolischer Spiralform.They show: FIG. 1 the side view of a reflector with a logarithmic mixer Spiral shape, Figure 2 shows the side view of a reflector with a spiral shape, the follows an exponential function, FIG. 3 shows the side view of a reflector parabolic spiral shape.

In allen drei Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen. Es bedeutet S die Strahlenquelle. Der Reflektor R erstreckt sich von A über M bis B, und die Bahn des Krümmungsmittelpunktes erstreckt sich von C über N nach D.In all three figures, the same parts are given the same reference numerals Mistake. It means S the radiation source. The reflector R extends from A. across M to B, and the path of the center of curvature extends from C across N to D.

Innerhalb des Reflektors sind die Strahlengänge der einzelnen Strahlen angedeutet. Die Pfeile zeigen die Richtung der Aussendung an.The beam paths of the individual rays are inside the reflector indicated. The arrows indicate the direction of the transmission.

Wie ersichtlich, zeigen die aus einem Spalt austretenden Strahlen eine gute Richtcharakteristik und sind von hoher Ausbeute, weil keine Verluste durch Eigenabschattung der Strahlenquelle mehr auftreten. Ferner ist die Herstellung gegenüber den bekannten Reflektoren wesentlich kostengünstiger L e e r s e i t eAs can be seen, show the rays emerging from a gap have a good directional characteristic and are of high yield because there are no losses through Self-shadowing of the radiation source occur more. Furthermore, the manufacturing is opposite the known reflectors much cheaper R e r s e i t e
