Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft eine Vorrichtung zur Beleuchtung mit einem Gehäuse, mit mindestens zwei in diesem angeordneten und von diesem getragenen Leuchtmitteln und mit elektrischen Steuermitteln zur Ansteuerung der Leuchtmittel. Derartige Beleuchtungsvorrichtungen werden z.B. zur Objektbeleuchtung in Einkaufszentren und hier insbesondere in speziellen Abteilungen, wie Bekleidungsbereiche, eingesetzt.The invention relates to a device for lighting with a housing, with at least two arranged in this and carried by this lamp and with electrical control means for controlling the lighting means. Such lighting devices are e.g. for object lighting in shopping centers and in particular in special departments, such as clothing areas used.

Stand der TechnikState of the art

Aus der DE 202 20 855 U1 ist eine Beleuchtungsvorrichtung bekannt, in welcher mehrere, in einem gemeinsamen Gehäuse untergebrachte Leuchtmittel mit unterschiedlichen Farbtemperaturen vorgesehen sind. Dabei ist wenigstens ein Kalttonleuchtmittel vorhanden, wobei die sich zu dem Gesamtlicht mischenden Lichtanteile der einzelnen Leuchtmittel dadurch variierbar sind, dass beide Leuchtmittel mittels eines Stereo-Potentiometers gegensinnig ansteuerbar sind. Da bei dieser Vorrichtung die Lichtanteile der einzelnen Leuchtmittel veränderbar sind, lassen sich individuelle Lichtbedingungen erzeugen.From the DE 202 20 855 U1 a lighting device is known in which a plurality of lamps housed in a common housing are provided with different color temperatures. In this case, at least one cold-tone illuminant is present, wherein the light components of the individual luminous means which mix with the total light can be varied in that both illuminants can be driven in opposite directions by means of a stereo potentiometer. Since the light components of the individual lamps can be changed in this device, individual lighting conditions can be generated.

Bei der Beleuchtung von Einkaufszentren ist es wünschenswert, eine Umschaltung der Beleuchtung von Tag- auf Nachtlicht vorzusehen, wobei tagsüber eine höhere Farbtemperatur des Lichts gewählt wird als in der Nacht. Für die Umschaltung der Lichtfarbe verwendet man in einer bekannten Lösung ein Konversionsfilter, das unter die Lampe geschwenkt wird. Alternativ dazu ist bekannt, eine Leuchte mit zwei getrennten Leuchtmitteln vorzusehen, wobei jedoch ein Nachteil dadurch entsteht, dass zum einen beide Leuchten keinen gemeinsamen Fokuspunkt aufweisen und sich zum anderen die beiden Leuchtmittel gegeneinander abschatten.When illuminating shopping malls, it is desirable to provide daylight switching to daylight, with a higher color temperature of the daytime being selected during the day than at night. For switching the light color is used in a known solution, a conversion filter, which is pivoted under the lamp. Alternatively, it is known to provide a lamp with two separate bulbs, but a disadvantage arises in that on the one hand, both lights have no common focus point and on the other, the two bulbs shade each other.

Aufgabe der ErfindungObject of the invention

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend weiterzuentwickeln, dass eine beleuchtungstechnisch optimierte Gestaltung erzielt wird. Zugleich soll sich die Vorrichtung in Serie zu effizienten Kosten mit möglichst geringem Bauteilaufwand herstellen lassen.The present invention has for its object to further develop a device of the type mentioned in that a lighting technology optimized design is achieved. At the same time, the device should be in Produce a series at an efficient cost with the lowest possible component cost.

Übersicht über die ErfindungOverview of the invention

Die Vorrichtung zur Beleuchtung von Objekten hat ein Gehäuse mit mindestens zwei in diesem angeordneten und von diesem getragenen Leuchtmitteln. Jedes der getrennt voneinander, zur Erzeugung einer jeweils vorgebbaren Farbtemperatur ansteuerbaren Leuchtmittel verfügt über eine separate Reflektoreinheit, mit dem es jeweils eine Lichtkammer bildet. Es sind Mittel zur gegenseitigen lichttechnischen Kopplung benachbarter Lichtkammern vorgesehen.The device for illuminating objects has a housing with at least two arranged in this and carried by this bulbs. Each of the separate from each other, for generating a respective predeterminable color temperature controllable lighting means has a separate reflector unit, with each of which forms a light chamber. Means are provided for mutual photovoltaic coupling of adjacent light chambers.

Nachfolgend werden spezielle Ausführungsformen der Erfindung definiert: Zunächst kann das Mittel zur gegenseitigen lichttechnischen Kopplung benachbarter Lichtkammern ein den Leuchtmitteln gemeinsam zugeordneter zweiter Reflektor sein. Der zweite Reflektor ist vorzugsweise durch ein sich oberhalb der Leuchtmittel durchgehend erstreckendes gewölbtes Band gebildet.In the following, specific embodiments of the invention are defined: First, the means for mutual photovoltaic coupling of adjacent light chambers may be a second reflector assigned to the light sources in common. The second reflector is preferably formed by an arched band extending continuously above the luminous means.

Alternativ oder ergänzend zum zweiten Reflektor sind die Mittel zur gegenseitigen lichttechnischen Kopplung benachbarter Lichtkammern lichtdurchlässige Bereiche an den benachbarten Reflektoreinheiten. Die lichtdurchlässigen Bereiche werden vorzugsweise durch Lochblenden in den einander zugewandten Lamellenbereichen der benachbarten Reflektoreinheiten gebildet. Die Lochblenden sind vorzugsweise jeweils im Bereich einer Mittellamelle der Reflektoreinheiten angeordnet.As an alternative or in addition to the second reflector, the means for mutual photovoltaic coupling of adjacent light chambers are transparent areas on the adjacent reflector units. The light-permeable regions are preferably formed by pinhole apertures in the mutually facing fin regions of the adjacent reflector units. The pinhole diaphragms are preferably each arranged in the region of a middle lamella of the reflector units.

Es sind zwei wahlweise schaltbare und/oder regelbare Leuchtmittel vorgesehen, wobei beide Leuchtmittel unterschiedliche Farbtemperaturen aufweisen können. Die jeweils aus Leuchtmitteln und die diesen jeweils zugeordneten separaten Reflektoreinheiten gebildeten Lichtkammern sind zum Objekt hin gemeinsam von einer Filterplatte abgeschlossen. Die Filterplatte ist für UV-Licht wirksam und gehärtet sowie vorzugsweise teilsatiniert, wodurch eine von der Satinierung ausgesparte Fläche verbleibt, die direkt unterhalb der Lichtaustrittsflächen aus den Lichtkammern liegt.There are two selectively switchable and / or controllable bulbs are provided, both bulbs may have different color temperatures. The light chambers formed in each case from light sources and the separate reflector units associated therewith are jointly closed by a filter plate towards the object. The filter plate is effective for UV light and cured and preferably partially satinated, leaving a recessed area of the satinization, which lies directly below the light exit surfaces of the light chambers.

Das Gehäuse ist z.B. von runder oder rechteckiger, insbesondere quadratischer, Gestalt. Am Gehäuse ist eine Gehäuseschulter vorhanden, die beim Einbau der Vorrichtung deren Abstützung in einer an einer Gebäudestruktur vorhandenen Aussparung dient. Die Gehäuseschulter ist beim bestimmungsgemässen Einbau in einer Variante an dem zum Raum hin gewandten Ende angeordnet. In einer anderen Variante ist die Gehäuseschulter in Richtung des zweiten Reflektors zurückgesetzt, so dass der erste Reflektor in den Raum ragt und von einem vorzugsweise transluzenten Ring umgeben ist.The housing is e.g. of round or rectangular, in particular square, shape. On the housing, a housing shoulder is present, which serves the installation of the device whose support in an existing on a building structure recess. The housing shoulder is arranged at the intended installation in a variant on the end facing the room. In another variant, the housing shoulder is set back in the direction of the second reflector, so that the first reflector protrudes into the space and is surrounded by a preferably translucent ring.

Die Lösung zeichnet sich dadurch aus, dass eine Einrichtung zur Beleuchtung von Objekten entsteht, bei der die Lichtkammer des derzeit ausgeschalteten Leuchtmittels durch einen Lichtanteil des eingeschalteten Leuchtmittels in der benachbarten Lichtkammer erhellt wird. Hierdurch ergibt sich eine einheitliche Lichtwirkung, ohne dass ungewollte Dunkelzonen im Gesamtreflektor entstehen. Dies erreicht man ohne aufwendige Bauteile.The solution is characterized in that a device for illuminating objects arises in which the light chamber of the currently switched off illuminant is illuminated by a light component of the switched on illuminant in the adjacent light chamber. This results in a uniform lighting effect, without causing unwanted dark zones in the overall reflector. This can be achieved without complex components.

Sind in einer Figur zum Zweck zeichnerischer Eindeutigkeit Bezugsziffern enthalten, aber im unmittelbar zugehörigen Beschreibungstext nicht erläutert, so wird auf deren Erwähnung in vorangehenden oder nachfolgenden Figurenbeschreibungen Bezug genommen. Im Interesse der Übersichtlichkeit wird auf die wiederholte Bezeichnung von Bauteilen in weiteren Figuren zumeist verzichtet, sofern zeichnerisch eindeutig erkennbar ist, dass es sich um "wiederkehrende" Bauteile handelt.The following definition applies to the entire further description. If reference numerals are included in a figure for the purpose of graphic clarity, but are not explained in the directly associated description text, reference is made to their mention in the preceding or following description of the figures. In the interest of clarity, the repeated designation of components in other figures is usually dispensed with, as far as the drawing clearly shows that they are "recurring" components.

Figuren 1A bis 1CFIGS. 1A to 1C

In dieser Figurengruppe hat die erfindungsgemässe Beleuchtungsvorrichtung die beispielhafte Gestalt einer runden Halbeinbauleuchte. Die Vorrichtung besteht im wesentlichen aus einem Gehäuse 1 mit einer zylindrischen Grundform. Das Gehäuse 1 sitzt innerhalb einer komplementären Aussparung 90, die in eine Gebäudestruktur 9 - z.B. eine Raumdecke oder ein Wandpaneel - eingebracht ist. Hierbei unterfasst eine nach aussen kragende Gehäuseschulter 10 den Rand der Aussparung 90. In den Raum ragend ist dem Gehäuse 1 ein Ring 15 aus vorzugsweise transluzentem Material vorgesetzt, der den ersten Reflektor 5 umgibt.In this group of figures, the lighting device according to the invention has the exemplary shape of a round semi-recessed luminaire. The device consists essentially of a housing 1 with a cylindrical basic shape. The housing 1 is seated within a complementary recess 90, which is introduced into a building structure 9 - for example a room ceiling or a wall panel. In this case, an outwardly projecting housing shoulder 10 underlines the edge of the recess 90. projecting into the space, the housing 1 is preceded by a ring 15 of preferably translucent material which surrounds the first reflector 5 .

Die Lichterzeugung erfolgt durch zwei Leuchtmittel 2a,2b, z.B. Hochdruckentladungslampen, wobei das Leuchtmittel 2a eine höhere Farbtemperatur (kältere Lichtfarbe) und das Leuchtmittel 2b eine niedrigere Farbtemperatur (wärmere Lichtfarbe) hat. Die beiden Leuchtmittel 2a,2b werden in Fassungen 4a,4b gehalten, die am Gehäuse 1 befestigt sind. Im Gehäuse 1 sind weitere herkömmliche elektronische Komponenten, wie Steuerglieder, Dimmer und elektronische Vorschaltgeräte, untergebracht, die nur schematisch angedeutet, und daher nicht bezeichnet sind. Jedes der Leuchtmittel 2a,2b weist eine separate Reflektoreinheit 3a,3b auf, die jeweils separate Lichtkammern a,b bilden, welche in das Innere eines darunter befindlichen ersten Reflektors 5 gerichtet sind. Der erste Reflektor 5 besitzt seitliche Durchbrüche 50 für den Lichtaustritt. Die Unterseite des ersten Reflektors 5 kann zum Raum hin mit einer transparenten Scheibe 6 abgeschlossen sein.The light is generated by two bulbs 2a, 2b, for example high-pressure discharge lamps, wherein the light source 2a has a higher color temperature (colder light color) and the light bulb 2b has a lower color temperature (warmer light color). The two lamps 2a, 2b are held in sockets 4a, 4b , which are fastened to the housing 1 . Housing 1 accommodates other conventional electronic components, such as control members, dimmers and electronic ballasts, which are indicated only schematically, and therefore not are designated. Each of the lighting means 2a, 2b has a separate reflector unit 3a, 3b , which respectively form separate light chambers a, b , which are directed into the interior of a first reflector 5 located thereunder. The first reflector 5 has lateral openings 50 for the light exit. The underside of the first reflector 5 can be closed to the room with a transparent pane 6 .

Die räumliche Trennung zwischen den Lichtkammern a,b der Reflektoreinheiten 3a,3b und dem ersten Reflektor 5 erfolgt durch eine Filterplatte 7, die als UV-Filterplatte ausgebildet ist. Sie besteht aus gehärtetem Material und ist auf ihrer Fläche teilweise satiniert, wobei der nicht-satinierte Bereich als ausgesparte Fläche 70 unterhalb der Lichtkammern a,b angeordnet ist. Zusätzlich wird der satinierte Bereich durch definiertes Streulicht aufgehellt. Die Reflektoreinheiten 3a,3b sind im Bereich ihrer einander zugewandten Mittellamellen als Lochblenden 30a,30b ausgebildet. Oberhalb beider Leuchtmittel 2a,2b ist ein durchgehender, sich entlang der Achse der Leuchtmittel 2a,2b erstreckender zweiter Reflektor 8 angeordnet, welcher derart gewölbt ist, dass das von ihm reflektierte Licht nach unten in die dem Leuchtmittel 2a,2b zugeordneten Reflektoreinheit 3a,3b strahlt. Gleichzeitig wird durch die Wölbung des zweiten Reflektors 8 erreicht, dass sich sein virtueller Brennpunkt nach oben hin verlagert und somit durch die Durchgängigkeit des zweiten Reflektors 8 bedingt, auch Licht des einen Leuchtmittels 2a in die Lichtkammer b der benachbarten Reflektoreinheit 3b strahlt und analog Licht des anderen Leuchtmittels 2b in die Lichtkammer a der zweiten Reflektoreinheit 3a gelangt.The spatial separation between the light chambers a, b of the reflector units 3a, 3b and the first reflector 5 is effected by a filter plate 7, which is designed as a UV filter plate. It is made of hardened material and is partially satin on its surface, wherein the non-frosted area is arranged as a recessed surface 70 below the light chambers a, b . In addition, the frosted area is brightened by defined stray light. The reflector units 3a, 3b are formed as pinhole apertures 30a, 30b in the region of their mutually facing center louvers . Above both light sources 2a, 2b there is a continuous second reflector 8 extending along the axis of the light sources 2a, 2b , which is curved in such a way that the light reflected by it is directed downwards into the reflector unit 3a, 3b associated with the light source 2a, 2b shine. At the same time, is achieved by the curvature of the second reflector 8 that its virtual focal point is displaced upwards and thus due to the continuity of the second reflector 8 and the light of a luminous means 2a radiates and into the light chamber b of the adjacent reflector unit 3b analog light of other bulb 2b passes into the light chamber a of the second reflector unit 3a .

Die erfindungsgemässe Vorrichtung arbeitet wie folgt: Es befindet sich jeweils eines der beiden Leuchtmittel 2a,2b im eingeschalteten Zustand, hier angenommen Leuchtmittel 2a. Das Licht in der Lichtkammer a des eingeschalteten Leuchtmittels 2a tritt durch die zugeordnete Reflektoreinheit 3a sowohl in den Bereich des ersten Reflektors 5 ein als auch über die Lochblenden 30a,30b und/oder den zweiten Reflektor 8 in die Lichtkammer b der benachbarten Reflektoreinheit 3b, dessen Leuchtmittel 2b momentan abgeschaltet ist. Hierdurch ergibt sich eine einheitliche Lichtwirkung unter Vermeidung von ungewollten Dunkelzonen im ersten Reflektor 5. Zudem entstehen zwei klare Fokuspunkte in den Reflektoreinheiten 3a,3b.The inventive device operates as follows: There is one of the two bulbs 2a, 2b in the on state, here assumed light source 2a. The light in the light chamber a of the switched on lighting means 2a both in the region of the first reflector 5 enters and through the pinhole 30a, 30b and / or the second reflector 8 in the light chamber b of the adjacent reflector unit 3b through the associated reflector unit 3a, whose Illuminant 2b is currently switched off. This results in a uniform lighting effect while avoiding unwanted dark zones in the first Reflector 5. In addition, two clear focus points in the reflector units 3a, 3b.

Figuren 2A bis 2CFIGS. 2A to 2C

Diese Figurengruppe zeigt die erfindungsgemässe Beleuchtungsvorrichtung in Gestalt einer quadratischen Einbauleuchte. Die nach aussen kragende Gehäuseschulter 10 des nun rechteckigen, vorzugsweise quadratischen Gehäuses 1, unterfasst wiederum den Rand der Aussparung 90, jedoch schliesst die Beleuchtungsvorrichtung quasi bündig mit der Aussenfläche der Gebäudestruktur 9 ab. Es ist kein Ring 15 vorgesehen, sondern die dem ersten Reflektor 5 optional vorzusetzende Scheibe 6 bildet den unteren Abschluss der Beleuchtungsvorrichtung. Ansonsten sind der innere Aufbau der Vorrichtung sowie deren Wirkungsweise zur zuvor beschriebenen runden Halbeinbauleuchte im Prinzip identisch.This group of figures shows the lighting device according to the invention in the form of a square recessed luminaire. The outwardly projecting housing shoulder 10 of the now rectangular, preferably square housing 1, in turn, underlies the edge of the recess 90, but the lighting device closes almost flush with the outer surface of the building structure 9. There is no ring 15 is provided, but the first reflector 5 optionally vorzusetzende disc 6 forms the lower end of the lighting device. Otherwise, the internal structure of the device as well as their mode of action for the previously described round semi-recessed luminaire are identical in principle.

Figuren 3A bis 3CFIGS. 3A to 3C

Diese Figurenfolge beruht auf einer Beleuchtungsvorrichtung, wiederum mit einem quadratischen Gehäuse 1, jedoch nun in der Anwendung als Halbeinbauleuchte. Das Gehäuse 1 ist innerhalb einer komplementären Aussparung 90 positioniert, die in der Gebäudestruktur 9 eingebracht ist. Erneut unterfasst die nach aussen kragende Gehäuseschulter 10 den Rand der Aussparung 90, und wiederum ist dem Gehäuse 1 ein zumindest partiell lichtdurchlässiger Ring 15 vorgesetzt, der den ersten Reflektor 5 umgibt. Damit kommt die Beleuchtungsvorrichtung etwa an ihrer mittleren Höhe an der Gebäudestruktur 9 zu liegen, wodurch sich die Einbautiefe verkleinert. Auch der innere Aufbau dieser Ausführungsform der Beleuchtungsvorrichtung sowie deren Wirkungsweise sind zu den vorherigen Ausführungsformen gleichartig.This sequence of figures is based on a lighting device, again with a square housing 1, but now in the application as semi-recessed luminaire. The housing 1 is positioned within a complementary recess 90 which is incorporated in the building structure 9. Again, the outwardly projecting housing shoulder 10 underlines the edge of the recess 90, and in turn the housing 1 is preceded by an at least partially transparent ring 15 which surrounds the first reflector 5. Thus, the lighting device comes to lie approximately at its average height on the building structure 9, whereby the installation depth is reduced. Also, the internal structure of this embodiment of the lighting device and its operation are similar to the previous embodiments.
