A wall or otherwise mounted light has a transparent cover (14) surrounding a lamp (16) housing (17) with a circular transparent section below a mounting surface (12). This section radiates intense useful light (15) while the surrounding cover transmits (31) diffused back lighting (33).

Description

Die Erfindung betrifft eine Anbauleuchte gemäß dem Oberbegriff des Anspruches 1.The invention relates to a surface-mounted luminaire according to the preamble of claim 1.

Eine derartige Anbauleuchte ist aus Fig.2 des DE 2 99 08 139 U1 in der Form einer lichtleitenden, vor allem über ihre Ränder abstrahlenden Platte, bekannt; das entsprechende Produkt ist unter der Handelsbezeichnung "Golden Eye" am Markt. Die Lichtplatte erfährt ihre Einstrahlung aus einem, in eine Durchgangsöffnung in der Platte eingesenkten, Halogenlampen-Strahlergehäuse, dessen Seitenwand wenigstens teilweise lichtdurchlässig ist. Die Lichtplatte wird vor einer Montagefläche, etwa in Form der Bodenplatte eines Oberschrankes der Küchenzeile über einer Arbeitsplatte, mittels einer einseitig am Glasrand angreifenden L-förmigen Halterung freitragend befestigt. Ein eigentliches Leuchten-Umgehäuse weist diese Anbauleuchte deshalb nicht auf.Such a surface-mounted luminaire is shown in Fig.2 of DE 2 99 08 139 U1 in the form of a photoconductive, especially on their edges radiating plate known; the corresponding product is marketed under the trade name "Golden Eye". The light plate undergoes its irradiation from a, in a through hole in the plate recessed, halogen lamp spotlight housing whose side wall is at least partially transparent. The light plate is mounted in front of a mounting surface, approximately in the form of the bottom plate of a wall unit of the kitchen unit above a worktop, cantilevered by means of an attacking on one side of the glass edge L-shaped bracket. An actual luminaire surrounding housing therefore does not have this surface-mounted luminaire.

Dagegen gehäuste Anbauleuchten sind etwa als die WIPO-Dreiecksleuchten auf dem Markt. Eine solche ist dafür bestimmt, mittels ihres Umgehäuses direkt unter die Montagefläche geschraubt zu werden, um aus dem in ihr Umgehäuse eingesetzten Halogenlampen-Strahlergehäuse heraus die darunter gelegene Arbeitsplatte zu beleuchten. Grundsätzlich kann eine solche Anbauleuchte aber auch vor einer vertikalen Wand montiert werden, etwa um die Absätze eines Treppenverlaufes auszuleuchten; wobei dann zum Blendschutz z.B. die Lichtleistung reduziert oder die Abstrahlrichtung der Normalen auf das Umgehäuse gegenüber, verschwenkt wird. Andere derartige Anbauleuchten bestehen aus einem länglichen, gewöhnlich ebenfalls aus Blech abgekanteten, kastenförmig geschlossenen Umgehäuse, in das etwa eine Zeile aus mehreren, gegen die darunter gelegene Arbeitsplatte gerichteten, Halogenlampen-Strahlerleuchten eingesetzt ist.Enclosed mounted luminaires are about as the WIPO triangle lights on the market. Such is intended to be screwed directly under the mounting surface by means of their Umgehäuses to illuminate from below the inserted in her surrounding housing halogen lamp spotlight out the underlying worktop. In principle, however, such a surface-mounted luminaire can also be mounted in front of a vertical wall, for example to illuminate the steps of a staircase; in which case, for example, reduces the light output for glare protection or the emission direction of the normal to the surrounding housing, is pivoted. Other such surface-mounted lights consist of an elongated, usually also folded from sheet metal, closed box-shaped enclosure, in which about a row of several, directed against the underlying worktop, halogen lamp spotlights is used.

Aus der DE 1 00 06 410 A1 (dort Fig.5 und Fig.7) sind gestreckte Deckenanbauleuchten mit Gasentladungs-Röhrenlampen hinter sichtseitigen Blendrastern bekannt. Beidseitig längs eines solchen Blendrasters erstrecken sich zwei konkav gekrümmte reflektierende Seitenflügel aus lichtdurchlässigem Material bis zur Anlage ihres jeweiligen freien Längsrandes gegen die Montagefläche. Sichtsseitig vor jedem dieser im Querschnitt geschwungen verlaufenden Reflektoren ist ein diesem gegenüber stärker gekrümmt verlaufender, einerseits am Blendraster gegenüber dem Reflektor versetzter und andererseits am gegenüberliegenden Längsrand des Reflektors endender Diffusor angeordnet. Dessen Versatz gegenüber dem Reflektor an der Längsseite des Blendrasters, quer zu seiner Längserstreckung, verhindert einen Blendeffekt infolge etwaiger direkter seitlicher Sicht gegen die Röhrenlampe. Dieser Versatz muß außerdem in einem ganz bestimmten Mindestverhältnis zur Flügelspannweite stehen. Er ermöglicht Lichteintritt von der Röhrenlampe durch eine Diffusorplatte hindurch in eine schmale dreieckförmige Lichtkammer hinter dem geschwungen verlaufenden Diffusor hinein, aus der dann die Abstrahlung durch den letzteren hindurch parallel zur Abstrahlung durch das Blendraster hindurch erfolgt. Da diese Abstrahlung aber nicht als ausreichend angesehen wird, ist hinter dem Blendraster, nämlich hinter jeder der beidseitigen Lichtkammern je eine weitere Röhrenlampe angeordnet, die durch den benachbarten Reflektor hindurch in dessen Lichtkammer einstrahlt.From the DE 1 00 06 410 A1 (There Fig.5 and Fig.7) are stretched ceiling mounted lights with gas discharge tube lamps behind visible side grids known. Along both sides of such a blind raster, two concavely curved reflective side wings of translucent material extend as far as their respective free longitudinal edge against the mounting surface. Seen in front of each of these curved in cross-section reflectors a more curved against this extending, on the one hand on the screen grid relative to the reflector offset and on the other hand at the opposite longitudinal edge of the reflector terminating diffuser is arranged. Its offset relative to the reflector on the longitudinal side of the screen grid, transverse to its longitudinal extent, prevents a glare effect due to any direct lateral view against the tube lamp. This offset must also be in a very specific minimum ratio to the wing span. It allows light entry from the tube lamp through a diffuser plate into a narrow triangular light chamber behind the curved diffuser, from which then the radiation through the latter takes place parallel to the radiation through the aperture grid. However, since this radiation is not considered sufficient, behind the glare grid, namely behind each of the two-sided light chambers each arranged a further tube lamp which radiates through the adjacent reflector into its light chamber.

Bei den zuvor erwähnten Anbauleuchten mit geschlossenem Umgehäuse besteht ein unangenehmer Helligkeitskontrast zwischen einerseits der örtlich scharf begrenzten gleißenden Intensität der gebündelten Abstrahlung aus der Gehäuseöffnung des Halogenstrahlergehäuses hinaus und andererseits dem Umgehäuse, in welches dieses Strahlergehäuse eingesenkt ist.In the case of the above-mentioned surface-mounted luminaires, there is an unpleasant brightness contrast between, on the one hand, the spatially sharply defined glittering intensity of the focused radiation from the housing opening of the halogen radiator housing and, on the other hand, the surrounding housing into which this radiator housing is sunk.

In Erkenntnis dieser Gegebenheiten liegt vorliegender Erfindung die technische Problemstellung zugrunde, bei einer preisgünstig fertigbaren und dennoch in ihrer Erscheinungsform vielfältig abwandelbaren Anbauleuchte gattungsgemäßer Art einen weniger krassen Beleuchtungseindruck zu erzielen und dadurch die Ausleuchtung visuell gefälliger zu gestalten und lichttechnisch noch zu verbessern.In recognition of these circumstances, the present invention is based on the technical problem to achieve a less glaring lighting impression at a reasonably priced and yet varied in their appearance versatile modification light generic type and thereby make the illumination visually pleasing and lighting technically even better.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Anbauleuchte gemäß den Merkmalen des Hauptanspruches ausgelegt ist, wonach das topfförmige Strahlergehäuse mit einer lichtdurchlässigen Wandung ausgestattet ist, durch die hindurch die eigentlich in Axalrichtung des Strahlergehäuses abstrahlende Lampe auch noch quer dazu abstrahlt; nämlich durch die Gehäusewandung hindurch in den seitlich sich anschließenden Hohlraum hinein, der rückwärtig durch die Montagefläche und im übrigen durch das Umgehäuse aus nun lichtdurchlässigem Material begrenzt ist. Dieses Kunststoffmaterial ist vorzugsweise nicht durchsichtig, sondern nur opak durchscheinend eingestellt und im Interesse einer diffusen Lichtabstrahlung mit aufgerauhter oder entsprechend lichtstreuend beschichteter Oberfläche ausgestattet. Das führt in der Einbauumgebung des Strahlergehäuses zu einer weniger intensiven zusätzlichen, geometrisch nach Maßgabe des Umgehäuses konfigurierten Lichtabstrahlung und dadurch zu einer angenehmen Helligkeitsabstufung vom hellen Lichtkegel des Nutzlichts aus dem Strahlergehäuse zur dunklen Umgebung der Montagefläche hin, mit gedämpftem Ausleuchten der Umgebung der hellen Nutzlichtzone auf der etwa darunter gelegenen Arbeitsplatte.This object is achieved in that the surface-mounted luminaire is designed according to the features of the main claim, after which the pot-shaped radiator housing is equipped with a translucent wall, through which radiates the actually radiating in the axial direction of the radiator housing lamp also transversely thereto; namely, through the housing wall into the laterally adjoining cavity, which is bounded at the rear by the mounting surface and, moreover, by the surrounding housing made of light-transmitting material. This plastic material is preferably not transparent, but only opaque translucent set and equipped in the interest of a diffuse light emission with roughened or correspondingly light-scattering coated surface. This results in the installation environment of the spotlight housing to a less intense additional, geometrically configured in accordance with the Umgehäuses light emission and thereby to a pleasant brightness gradation of the bright light cone of Nutzlichts from the spotlight housing to the dark environment of the mounting surface, with muted illumination of the environment of the bright Nutzlichtzone the worktop below it.

So wirkt das Umgehäuse des Strahlergehäuses nun nicht mehr als bloßes, visuell eher störendes Konstruktionselement zur Aufnahme des Strahlergehäuses, sondern als gefälliges Lichtobjekt. Diese Wirkung wird noch dadurch gefördert, daß seitlich durch das Strahlergehäuse hindurch in das lichtleitende Material des Umgehäuses Licht eingestrahlt wird, das daraus dann an der aufgerauhten oder mit Rauhlack belegten Oberfläche des Umgehäuses in der Umgebung des Strahlergehäuses großflächig abgestrahlt wird.Thus, the peripheral housing of the radiator housing now no longer acts as a mere, visually rather disturbing structural element for receiving the radiator housing, but as a pleasing light object. This effect is further promoted by the fact that light is radiated laterally through the radiator housing into the light-conducting material of the surrounding housing, which is then radiated over a large area thereof from the roughened or roughened surface of the surrounding housing in the vicinity of the radiator housing.

Jedenfalls werden für das nun strahlende Umgehäuse zweckmäßigerweise gefällige geometrische Formen unabhängig von den Einbauerfordernissen für das Strahlergehäuse in Betracht gezogen. Solche Formen sind abgesehen von der rechtwinklig zur Montageplatte begrenzten Kastenausbildung vor allem Formen, die aus der Ebene der Einbauhöhe des Strahlergehäuses zur Ebene der Montagefläche hin auslaufen, wie ein stumpfwinkliger Hohlkegelstumpf, ein Tellerprofil oder eine Hohlkugelkappe mit in ihren Polbereich eingesetztem Strahlergehäuse, aber auch etwa ein in Draufsicht dreieckförmiger oder rechteckiger Keil.In any case, conveniently compliant geometric shapes are considered regardless of the installation requirements for the radiator housing for the now radiant enclosure. Such forms are apart from the right angles to the mounting plate limited box training, especially forms that leak from the plane of installation height of the radiator housing to the mounting surface, such as an obtuse Hollow truncated cone, a plate profile or a hollow spherical cap with inserted into their pole area radiator housing, but also about a triangular in plan view or rectangular wedge.

Bezüglich zusätzlicher Alternativen und Weiterentwicklungen sowie deren Vorteilen wird außer auf die weiteren Ansprüche auf nachstehende Beschreibung eines in der Zeichnung vereinfacht aber angenähert maßstabsgerecht skizzierten bevorzugten Realisierungsbeispiels verwiesen. Die einzige Figur der Zeichnung zeigt im Axial-Querschnitt ein lichtdurchlässiges Strahlergehäuse in einem lichtleitenden, in diesem Falle flach hohlkegelstumpfförmigen Umgehäuse unter einer Montagefläche.With regard to additional alternatives and further developments as well as their advantages, reference is made to the following description of a preferred implementation example sketched in the drawing but approximately to scale, with the exception of the further claims. The single FIGURE of the drawing shows in the axial cross-section of a light-transmitting radiator housing in a light-conducting, in this case flat hollow truncated cone-shaped housing under a mounting surface.

Im skizzierten Realisierungsbeispiel liefert der Unterboden 11 etwa des Oberschrankes einer Küchenzeile die Montagefläche 12 für eine Anbauleuchte 13. Die weist in einem Umgehäuse 14 ein Strahlergehäuse 17 auf, das axial - und damit quer zur Montagefläche 12 - Nutzlicht 15 von einer hellen Lampe 16 abstrahlt. Bei dieser handelt es sich insbesondere um eine Halogenlampe, gegebenenfalls aber auch etwa um eine kompakte Leuchtstoff-Lampe vor einer planen Reflektorscheibe 32 auf dem Gehäuseboden des Strahlergehäuses 17. Nicht sichtbar ist in der Skizze, daß im Interesse eines axial flachen Strahlergehäuses 17 dessen Lampe 16 in einer quer zur Gehäuseachse 30 orientierten Steckhalterung ruht und die Versorgungsleitung dorthin durch eine Öffnung im axial hinteren Bereich des Strahlergehäuses 17 sowie eine örtlich korrespondierende Öffnung in der Strahler-Halterung 23 im Umgehäuse 14 verläuft.In the example of implementation sketched, the underfloor 11, for example, of the upper cabinet of a kitchen unit supplies the mounting surface 12 for a surface-mounted luminaire 13. The latter has a radiator housing 17 in a surrounding housing 14 which radiates useful light 15 from a bright lamp 16 axially and thus transversely to the mounting surface 12. This is in particular a halogen lamp, but possibly also about a compact fluorescent lamp in front of a plane reflector disk 32 on the housing bottom of the radiator housing 17. Not visible in the sketch that in the interest of an axially flat radiator housing 17 whose lamp 16th rests in a transverse to the housing axis 30 oriented plug holder and the supply line there through an opening in the axially rear portion of the radiator housing 17 and a locally corresponding opening in the radiator holder 23 in the housing 14 extends.

Bei skizzierten Beispielsfalle entspricht der Durchmesser des handelsüblich topfförmigen Strahlergehäuses 17 der kleineren Deckfläche eines Umgehäuses 14 in Form eines flachen, stumpfwinkligen Hohlkegelstumpfes, dessen umlaufende Wandung 18 sich von dieser Ebene axial bis zur Montagefläche 12 hin erstreckt und so dort die große Grundfläche des Kegelstumpfes aufspannt. Ein kaft- oder formschlüssig auf die Nutzlicht-Abstrahlöffnung 19 des Strahlergehäuses 17 aufsetzbarer Ring 20 ist als Berührungsschutz vor der Lampe 16 mit einer Scheibe 21 ausgestattet und dient im Übrigen als den Rand der Einsenköffnung 22 in der Wandung 18 umlaufend radial übergreifend kaschierender Kragen.In sketched example trap, the diameter of the commercially cup-shaped radiator housing 17 corresponds to the smaller top surface of a Umgehäuses 14 in the form of a flat, obtuse hollow truncated cone whose peripheral wall 18 extends axially from this plane to the mounting surface 12 and so spans there the large base of the truncated cone. A kaft- or positive fit on the Nutzlicht-radiation opening 19 of the radiator housing 17 attachable ring 20 is provided as a contact protection in front of the lamp 16 with a disc 21 and serves as the edge of the Einsenköffnung 22 in the wall 18 circumferentially radially overlapping laminating collar.

Das Strahlergehäuse 17 kann unmittelbar in der Einsenköffnung 22 im Umgehäuse 14 kraft- oder formschlüssig gehaltert sein. Zweckmäßiger sind jedoch an die Wandung 18 hinter ihrer Einsenköffnung 22 achsparallel das Strahlergehäuse 17 umgebend angeformte Halterungen 23, etwa wie skizziert in Form eines geschlossenen Hohlzylinders oder auch nur in Form einzelner achsparalleler Zungen (nicht dargestellt). An diese Halterung 23 können radial wirkende Federelemente angespritzt sein, aber bei Anwendung der Standardform von Halogenstrahlergehäusen 17 sind die schon in deren hohlzylindrische Gehäusewandung integriert.The emitter housing 17 may be retained in the housing housing 14 in a force-locking or form-fitting manner directly in the recessed opening 22. Appropriately, however, the radiator housing 17 are integrally formed on the wall 18 behind its Einsenköffnung 22 parallel to the axis Mounts 23, as sketched in the form of a closed hollow cylinder or only in the form of individual axially parallel tongues (not shown). At this bracket 23 radially acting spring elements may be injection-molded, but when using the standard form of Halogenstrahlergehäusen 17 which are already integrated in the hollow cylindrical housing wall.

Die Halterung 23 im Umgehäuse 14 zur Aufnahme des Strahlergehäuses 17 kann wie skizziert topfförmig mit einem geschlossenen Boden 24 ausgestaltet sein, um der Montagefläche 12 gegenüber einen Wärmeschutz zu realisieren und um durch diesen Boden 24 hindurch die Anbauleuchte 13 etwa mittels Schrauben 25 vor der Montagefläche 12 zu befestigen. Für diese Befestigung genügt es insbesondere bei geringerer thermischer Beanspruchung seitens des Strahlergehäuses 17 aber auch, statt eines geschlossenen Bodens 24 an das innere Ende der Halterung 23 nur eine diametral verlaufende Schiene anzuformen, oder sogar nur einige kurze, quer zur Gehäuseachse 30 radial abgewinkelte Laschen zur Aufnahme von Schraubenlöchern.The holder 23 in the surrounding housing 14 for receiving the radiator housing 17 may be designed as cup-shaped with a closed bottom 24 in order to realize the mounting surface 12 against thermal protection and through this floor 24 through the surface mounted light 13, for example by means of screws 25 in front of the mounting surface 12th to fix. For this attachment, it is sufficient in particular at lower thermal stress from the radiator housing 17 but also, instead of a closed bottom 24 to the inner end of the holder 23 to form only a diametrically extending rail, or even just a few short, transversely to the housing axis 30 radially angled tabs Inclusion of screw holes.

Bei dieser Montage der Anbauleuchte 13 liegt der freie Stirnrand 26 des Umgehäuses 14, seiner Einsenköffnung 22 axial gegenüber, bündig gegen die Montagefläche 12 an und begrenzt dadurch den Hohlraum 27 hinter der Wandung 18 des Umgehäuses 14. Die axiale Höhe des Umgehäuses 14 ist zweckmäßigerweise etwas größer als die axiale Länge der Halterung 23; womit einerseits eine ringsum satte Anlage des Umgehäuses 14 gegen die Montagefläche 12 und andererseits im Zentrum des Umgehäuses 14 eine zusätzliche thermische Entkopplung gegeben ist, die erforderlichenfalls durch nichtmetallische Abstandhalter 28 etwa in Form von Unterlegscheiben an den Schrauben 25 noch gefördert wird.In this mounting of the surface-mounted luminaire 13, the free end edge 26 of the surrounding housing 14, its Einsenköffnung 22 axially opposite, flush against the mounting surface 12 and thereby limits the cavity 27 behind the wall 18 of the Umgehäuses 14. The axial height of the Umgehäuses 14 is expediently something larger than the axial length of the bracket 23; on the one hand a round all-round investment of the Umgehäuses 14 against the mounting surface 12 and on the other hand in the center of the Umgehäuses 14 an additional thermal decoupling is given if necessary by non-metallic spacer 28 in the form of washers on the screws 25 is still promoted.

Zumindest die hohlzylindrisch umlaufende Seitenwand des in das Umgehäuse 14 eingesenkten Strahlergehäuses 17 besteht, wie dessen Halterung 23, aus lichtdurchlässigem Material, etwa hitzebeständig eingestelltem Acrylglas. Dadurch bewirkt die Lampe 16, neben ihrer durch die Spiegelplatte 32 dominierten axialen Hauptabstrahlung von Nutzlicht 15, in Querrichtung bezüglich der Gehäuseachse 30 eine Einstrahlung 29 in das lichtleitende Material der Wandung 18 des Umgehäuses 14. Aus dieser lichtleitenden Wandung 18 wird infolge deren Oberflächengestaltung die zentrale Einstrahlung 29 großflächig wieder ausgekoppelt, um dadurch das gesamte, das eigentliche Strahlergehäuse 17 einfassende, Umgehäuse 14 seiner geometrischen Form entsprechend in Streulicht 31 erstrahlen zu lassen, was in wünschenswerter Weise visuell von der sonst dominierenden, hellen zentralen Abstrahlöffnung 19 ablenkt.At least the hollow cylindrical circumferential side wall of the recessed into the surrounding housing 14 radiator housing 17, as the holder 23, made of translucent material, such as heat-resistant set acrylic glass. As a result, the lamp 16, in addition to its dominated by the mirror plate 32 axial main emission of useful light 15, in the transverse direction with respect to the housing axis 30, an irradiation 29 in the photoconductive material of the wall 18 of the Umgehäuses 14. From this photoconductive wall 18 is due to their surface design, the central Irradiation 29 coupled out over a large area again, in order to allow the entire, the actual spotlight housing 17 enclosing, surrounding housing 14 of its geometric shape in accordance with scattered light 31, which visibly detracts visually from the otherwise dominant, bright central radiation aperture 19.

Dieser Effekt der Verlagerung des visuellen Eindrucks vom Zentrum zum Umgehäuse 14 hin wird noch verstärkt, wenn dessen Wandung 18 zusätzlich dadurch aufgehellt wird, daß auch noch, axial versetzt gegenüber der Lichtleiter-Einstrahlung 19 in der Ebene der Einsenköffnung 22, parallel zur Oberfläche der Spiegelplatte 32 durch das Strahlergehäuse 17 hindurch eine Hinterleuchtung 33 der lichtdurchlässigen Wandung 18 des Umgehäuses 14 in seinem Hohlraum 27 erfolgt.This effect of shifting the visual impression from the center to the surrounding housing 14 is further enhanced when its wall 18 is additionally brightened by the fact that it is also offset axially relative to the optical fiber irradiation 19 in the plane of the recess 22, parallel to the surface of the mirror plate 32 through the radiator housing 17 through a backlight 33 of the translucent wall 18 of the Umgehäuses 14 takes place in its cavity 27.

Wenn entgegen der vereinfachten Darstellung in der Zeichnung kein Umgehäuse 14 mit im Querschnitt linearem Verlauf seiner Wandung 18 eingesetzt wird, sondern etwa ein tellerförmig oder kugelkappenförmig geschwungen verlaufendes und dementsprechend die Abstrahlrichtung des Streulichts 31 variierendes Umgehäuse 14, kommt die Oberflächengestaltung des Umgehäuses 14 besonders plastisch zur Geltung. Außerdem läßt sich dadurch die Intensität und räumliche Verteilung der Streulichtabstrahlung 31 in der Umgebung des Nutzlichts 15 konstruktiv in weiten Grenzen beeinflussen.If, contrary to the simplified representation in the drawing, no surrounding housing 14 is used with a linear cross-sectional profile of its wall 18, but about a plate-shaped or spherical cap-shaped curved extending and accordingly the emission direction of the scattered light 31 varying surrounding housing 14, the surface design of the surrounding housing 14 is particularly plastic validity. In addition, the intensity and spatial distribution of the scattered light emission 31 in the vicinity of the useful light 15 can thereby be structurally influenced within wide limits.

Eine Anbauleuchte 13, wie sie vor einer Wand oder insbesondere unter einer Tragplatte montiert wird und in ihrem Umgehäuse 14 ein Strahlergehäuse 17 für beispielsweise eine Halogenlampe 16 aufnimmt, erhält somit erfindungsgemäß ein gefälligeres Aussehen bei verbesserten lichttechnischen Eigenschaften, wenn unter fertigungsunkritischem Übergang von Blech auf lichtleitenden Kunststoff für das Umgehäuse 14 zusätzlich zur intensiven axialen Abstrahlung des Nutzlichts 15 aus dem Strahlergehäuse 17 heraus dessen Umgehäuse 14 eine Abstrahlung von weniger intensivem und dadurch die Formwirkung betonendem Streulicht 31 um den Nutzlichtkegel 15 herum liefert. Dafür strahlt die Lampe 16 zusätzlich durch die durchscheinende Wand des Strahlergehäuses 17 hindurch in die lichtleitende Wandung 18 des Umgehäuses 14 und / oder in den Hohlraum 27 hinter dieser Wandung 18 hinein, wobei die Helligkeitswirkung des Streulichts 31 gemäß der geometrischen Formgebung des Umgehäuses 14 variiert.A surface-mounted luminaire 13, as it is mounted in front of a wall or in particular under a support plate and accommodates a spotlight housing 17 for example, a halogen lamp 16 in its surrounding housing 14, thus receives according to the invention a pleasing appearance with improved photometric properties when under non-production critical transition from sheet to photoconductive Plastic for the surrounding housing 14 in addition to the intense axial radiation of the useful light 15 from the radiator housing 17 out the surrounding housing 14 provides a radiation of less intense and thus the shape effect accentuated stray light 31 to the Nutzlichtkegel 15 around. For this purpose, the lamp 16 additionally radiates through the translucent wall of the radiator housing 17 into the light-conducting wall 18 of the surrounding housing 14 and / or into the cavity 27 behind this wall 18, wherein the brightness effect of the scattered light 31 varies in accordance with the geometric shape of the surrounding housing 14.
