Abstract

The channel type reflector for lamps has a concave reflecting surface around the lamp axis. This reflector is used for lamps of small surface area, and with high illumination density. The light is accurately guided with low loss of light, for example when using clear bulbs. The reflecting surface (3) consists of a number of strip shaped longitudinal reflectors. These elemental reflectors can have a convex or concave shape relative to their axis of orientation. This arrangement ensures that light diffusion losses are low and light is reflected accurately in the required direction.

Description

Rinnenreflektor Gutter reflector

Die vorliegende Erfindung bezieht sich auf einen Rinnenreflektor für Lampen,der eine um die als Lampenachse bezeichnete Orientierungsachse zylindrische oder gevölbte Reflexionsfläche aufweist.The present invention relates to a gutter reflector for Lamp, which has a cylindrical orientation axis called the lamp axis or has convex reflective surface.

Beim verwenden von Lampen mit einer grossen leuchtenden Fläche werden Reflektoren mit Spiegelreflexionsflächen zur Lichtlenkung verwendet. Je grösser die leuchtende Fläche ist, umso geringer sind die Anforderungen an die Genauigkeit der geometrischen Verhältnisse zwischen Reflexionsflächeund Leuchtfläche, ohne dass die Genauigkeit der Lichtlenkung beeinträchtigt wird.When using lamps with a large luminous area Reflectors with mirror reflection surfaces are used to direct light. The bigger the luminous surface, the lower the requirements for accuracy the geometric relationships between the reflective surface and the luminous surface without the accuracy of the light control is impaired.

Bei der Verwendung von Lampen mit kleiner Fläche hoher Leuchtdichte, wie z.B. Lampen mit Klarglaskolben, können meist keine Reflektoren mit Spiegelreflexionsflächen verwendet verden, da die geometrischenAbmessungen einer Lampe innerhalb zu weiter Grenzen schwanken, als dass eine brauchbare Lichtaenkung noch möglich wäre. FUr solche Lampen werden daher zur Lichtlenkung Reflektoren mit mikroskopisch rauhen, stark streuenden Reflexionsflächen verwendet. Die Lichtverluste bei solchen Reflektoren sind indessen gross.When using lamps with a small area of high luminance, such as lamps with clear glass bulbs can usually not have reflectors with mirror reflection surfaces are used because the geometric dimensions of a lamp are too wide within Limits fluctuate so that a useful deflection of the light would still be possible. For Such lamps are therefore used to direct light reflectors with microscopically rough, strongly scattering reflective surfaces are used. The light losses with such reflectors are, however, great.

Die vorliegende Erfindung stellt sich die Aufgabe, einen Rinnenreflektor für Lampen mit einer kleinen Fläche hoher Leuchtdichte und üblichen Abmessungstoleranzen zu schaffen, der bei geringen Lichtverlusten eine genaue Lichtlenkung ermöglicht.The object of the present invention is to provide a gutter reflector for lamps with a small area of high luminance and usual dimensional tolerances to create that enables precise light control with low light losses.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen: Fig.l Einen zur Lampenachse rechtwinkligen Querschnitt durch ein erstes Ausführungsbeispiel eines Rinnenreflektors, Fig.2 eine gleiche Darstellung wie Fig.l eines zweiten Ausführungsbeispiels und Fig.3 eine gleiche Darstellung wie Fig.l eines dritten Ausführungsbeispiels.The invention is illustrated by means of the accompanying schematic drawing for example explained. Show it: Fig.l One to the lamp axis right-angled cross-section through a first embodiment of a gutter reflector, FIG. 2 shows the same representation as FIG. 1 of a second exemplary embodiment and 3 shows the same representation as FIG. 1 of a third exemplary embodiment.

In der Zeichnung bezeichnet die Hinweisziffer 1 einen Rinnenreflektor mit der als Lampenachse 2 bezeichneten Orientierungsachse, zu der achsial die nicht dargestellte Lampenfassung in der Leuchte angeordnet ist. Die Innenseite des Reflektors 1 bildet die Reflexionsfläche 3, welche als Spiegelfläche ausgebildet und in Längsrichtung des Reflektors in aneinandergrenzende Streifen 4 unterteilt ist. Die Streifen 4 weisen einen gegen die Lampenachse 2 konvexen Querschnitt auf. Dadurch wird das Licht nicht in die Lampenachse 2 enthaltende Ebenen gestreut sondern nur in Richtungen, die zum Nutzlichtstrom beitragen.In the drawing, reference number 1 denotes a gutter reflector with the orientation axis designated as lamp axis 2, to which axially it is not The lamp socket shown is arranged in the luminaire. The inside of the reflector 1 forms the reflection surface 3, which is designed as a mirror surface and extends in the longitudinal direction of the reflector is divided into adjacent strips 4. The strips 4 have a cross section that is convex towards the lamp axis 2. This will make that Light is not scattered in planes containing lamp axis 2 but only in directions which contribute to the useful luminous flux.

Bei den Ausführungsbeispielen nach den Fig.2 und 3 bezeichnen gleiche Hinweisziffern aequivalente Teile wie in Fig.l. Im Unterschied zum ersten Beispiel sind in Fig.2 die Streifen 4 der Reflexionsfläche 3 gegen die Lampenachse 2 konkav und nicht konvex ausgebidet, wogegen beim Beispiel nach Fig.3 die einzelnen Streifen 4 einen V-förmigen Querschnitt aufweisen.In the embodiments according to FIGS. 2 and 3 denote the same Reference numbers for equivalent parts as in Fig.l. In contrast to the first example In Figure 2, the strips 4 of the reflective surface 3 are concave towards the lamp axis 2 and not convex, whereas in the example according to FIG. 3 the individual strips 4 have a V-shaped cross section.

Eine praktisch brauchbare Lichtlenkung wird bereits dann erreicht, wenn die im Bereich des Reflektorrandes 5 liegenden Teile der Reflexionsfläche 3 in Streifen 4 unterteilt sind. L e e r s e i t eA practically usable light control is already achieved when the parts of the reflective surface 3 located in the area of the reflector edge 5 are divided into strips 4.
