Abstract
Description
Die Erfindung betrifft eine Leuchte, insbesondere eine Langfeldleuchte, mit einem Leuchtengehäuse, mindestens einem Primärleuchtmittel, einem dem Primärleuchtmittel zugeordneten optischen System und einem Sekundärleuchtmittel.The The invention relates to a luminaire, in particular a linear luminaire, with a luminaire housing, at least one primary illuminant, one of the primary illuminants associated optical system and a secondary illuminant.
Derartige Langfeldleuchten werden zur entblendeten Beleuchtung einer Sehaufgabe eingesetzt, insbesondere in Bürogebäuden und öffentlichen Gebäuden. Die Leuchtstofflampe fungiert dabei als Primärbeleuchtung, welche mit dem optischen System einen entblendet gerichteten Lichtstrahl auf die Sehaufgabe lenkt. Als optisches System kommen zusätzlich zu Reflektoren neben Rastern auch diffuse Leuchtabdeckungen in Form von Wannen oder Platten, vorzugsweise aus Kunststoff zum Einsatz.such Linear luminaires become glare-free lighting for a visual task used, especially in office buildings and public Buildings. The fluorescent lamp acts as a primary lighting, which with the optical system a blinding directed light beam on the Visual task distracts. As an optical system in addition to Reflectors in addition to grids and diffuse light covers in shape of trays or plates, preferably of plastic used.
Dabei werden öffentliche und private Gebäude immer häufiger außerhalb der Bürozeiten durch eine farblich abgesetzte Akzentbeleuchtung zur Erzeugung einer besonderen Atmosphäre eingesetzt. Für eine solche statische und farbliche Akzentbeleuchtung werden häufig Leuchtdioden in separaten Leuchten eingesetzt, was neben der technischen Beleuchtung für die Primärbeleuchtung weitere Leuchten erforderlich macht. Mitunter wird die farbig akzentuierte Sekundärbeleuchtung auch in den Gehäuserand der Primärbeleuchtung eingebaut.there become public and private buildings more frequently outside the office hours by a contrasting accent lighting to produce a special atmosphere used. For Such static and color accent lighting often become LEDs used in separate lights, which in addition to the technical lighting for the primary lighting makes additional lights necessary. Sometimes the color is accentuated secondary lighting also in the edge of the case the primary lighting built-in.
Ausgehend von dem eingangs genannten Stand der Technik liegt der Erfindung das technische Problem zugrunde, die zuvor genannten Nachteile zumindest teilweise zu vermeiden und eine gattungsgemäße Leuchte, insbesondere eine Langfeldleuchte, vorzusehen, die eine besonders einfache und unscheinbare Kombination der Primärbeleuchtung mit einer Akzentbeleuchtung ermöglicht.outgoing from the above-mentioned prior art, the invention the technical problem, the disadvantages mentioned above at least partly to avoid and a generic lamp, in particular a Linear luminaire, to provide a particularly simple and inconspicuous Combination of primary lighting with accent lighting.
Erfindungsgemäß wird dieses bei einer Leuchte der eingangs genannten Art dadurch gelöst, dass das Sekundärleuchtmittel als farblich akzentuiertes LED-Leuchtmittel oberhalb des Primärleuchtmittels angeordnet ist. Durch den Einsatz einer oder mehrerer, vorzugsweise farbiger LEDs innerhalb des optischen Systems der Primärbeleuchtung, können beide Lichtquellen ein und dasselbe optische System benutzen. Die besten Resultate bezüglich einer gleichmäßigen Ausleuchtung der Lichtaustrittsfläche werden erzielt, wenn die LEDs oberhalb des Primärleuchtmittels angeordnet sind. Bei der erfindungsgemäßen Ausbildung bildet das mit Leuchtstoffen beschlämmte Lampenrohr der Leuchtstofflampe einen primären Diffusor der Primärlichtquelle emittierten Lichtes, während die wannen- oder scheibenförmige Abdeckung der Leuchte als sekundäre Optik fungiert. Hierdurch werden Farberscheinungen in ungleichmäßiger Ausleuchtung auf der Wanne (Scheibe) der Leuchte erheblich minimiert oder durch geeignete Kombination auch gänzlich ausgeschlossen. Das optische System kann aus einer lichtstreuenden Abdeckung oder einem diffus streuenden Reflektor bestehen, z. B. für T5-Leuchtstofflampen. Vorzugsweise ist das farbig akzentuierte Sekundärleuchtmittel oberhalb des Primärleuchtmittels angeordnet. Das Primärleuchtmittel ist aufgrund des kompakten Aufbaus vorzugsweise als T5-Leuchtstofflampe ausgebildet. Die LED-Leuchtmittel sind vorzugsweise als LED-Streifen mit mehreren LED-Lampen ausgebildet und können entweder einfarbig oder unterschiedlich farbig ausgestaltet sein.According to the invention this in a lamp of the type mentioned solved in that the secondary illuminant as a color accentuated LED illuminant above the primary illuminant is arranged. By using one or more, preferably colored LEDs within the optical system of primary lighting, can both Light sources use the same optical system. The best Results re a uniform illumination the light exit surface achieved when the LEDs are located above the primary illuminant. In the embodiment of the invention forms the luminescent lamp lamp tube of the fluorescent lamp a primary Diffuser of the primary light source emitted light while the pan or disc-shaped cover the lamp as a secondary Optic acts. As a result, color effects in uneven illumination on the tub (disc) of the lamp significantly minimized or by suitable combination also thoroughly locked out. The optical system can be made of a light-scattering Cover or diffuse scattering reflector consist, for. B. for T5 fluorescent lamps. Preferably, the colored accentuated secondary illuminant is above the Primary light source arranged. The primary light source is due to the compact design preferably as a T5 fluorescent lamp educated. The LED bulbs are preferably designed as LED strips with multiple LED lamps and can either monochrome or differently colored be configured.
Vorzugsweise ist die Leuchte eine als sekundäre Optik fungierende Leuchtenabdeckung, z. B. aus einem opalen Kunststoff oder Glaskörper.Preferably the lamp is one as secondary Optically functioning light cover, z. B. of an opal plastic or vitreous body.
Weitere Einzelheiten, Vorteile und Details sind aus der beigefügten Figurenbeschreibung entnehmbar.
