Nærværende opfindelse angår et lysarmatur med fæste for en holder til en elektrisk lyskilde.The present invention relates to a light fixture with bracket for a holder for an electric light source.

Ifølge gældende elektrotekniske normer kræves en minimumafstand mellem stærkstrømsledninger, som er fast-5 gjort ved en glødelampes holder, så at disse er adskilt på en berørings- og ovérslagssikker måde.According to current electrotechnical standards, a minimum distance between high current lines, which is fixed at the holder of an incandescent lamp, is required so that they are separated in a touch and cover-safe manner.

Dette krav baserer sig på, at en sædvanlig PVC-isoleret installationsledning risikerer at skades af varmeudviklingen fra f.eks. en 60 eller 75 watt gløde-10 lampe i et stærkstrømsanlæg.This requirement is based on the fact that a conventional PVC insulated installation pipe risks being damaged by the heat generation from e.g. a 60 or 75 watt glow-10 lamp in a high-power system.

Sædvanligvis løser armaturfabrikanten dette problem gennem at udruste armaturen med en i passende afstand fra lampeholderen beliggende plint, samt varmebe-standigt isolerede ledere fra plinten til holderens til-15 slutninger. Derved kan elinstallatøren montere sine sædvanlige installationsledninger i plinten.Usually, the luminaire manufacturer solves this problem by equipping the luminaire with a terminal located at a suitable distance from the lamp holder, as well as heat-resistant insulated conductors from the terminal to the holder terminals. This allows the electrician to install his usual installation wiring in the terminal block.

Dette arrangement indebærer dog en væsentlig fordyrelse af produktet, gennem behovet for en plint, var-mebeståndigt isoleret ledning og monteringen af disse på 20 armaturen.However, this arrangement involves a substantial costing of the product, through the need for a plinth, heat-resistant insulated wire and the mounting thereof on the luminaire.

Formålet med nærværende opfindelse er at frembringe et armatur, som opfylder nævnte krav på en enklere og billigere måde.The object of the present invention is to provide a luminaire which satisfies said requirements in a simpler and cheaper way.

Et lysarmatur ifølge opfindelsen er ejendommeligt 25 ved, at armaturdelen er forsynet med i det mindste én skillevæg på den i forhold til fæstet modsat liggende side af armaturdelen, at fæstet er afsluttet med en fra nævnte side tilgængelig åbning, og at skillevæggen er således placeret i forhold til åbningen og har en sådan 30 udstrækning, at den tvangsmæssigt fastlægger en acceptabel berørings- og overslagssikker afstand mellem tilslutningsledninger til tilslutningsorganer hos den lampeholder, som er beregnet til at optages i fæstet langs en forudbestemt strækning fra nævnte tilslutningsorga-35 ner.A light fixture according to the invention is peculiar in that the luminaire part is provided with at least one partition on the opposite side of the luminaire part, that the luminaire is completed with an opening available from said side and that the partition is thus placed in in relation to the aperture and has such an extent that it forcibly establishes an acceptable touch and clearance safe distance between connecting leads to connecting means of the lamp holder which is intended to be received in the bracket along a predetermined distance from said connecting means.

Ifølge en egnet udførelsesform for opfindelsen slår skillevæggen uden nævneværdig afstand bro overAccording to a suitable embodiment of the invention, the partition wall bridges without appreciable distance

2 nævnte åbning og er hensigtsmæssigt i det mindste 8 mm bred.2 is suitably at least 8 mm wide.

Ifølge yderligere en egnet udførelsesform grænser to skillevægge med en indbyrde mellemliggende 5 luftspalte indtil lampeholderens tilslutningsende og afstanden mellem skillevæggenes fra hinanden bortvendende sider er mindst 8 mm.According to a further suitable embodiment, two partitions adjoin an intermediate air gap until the terminal end of the lamp holder and the distance between the sides of the partitions facing away are at least 8 mm.

Hensigtsmæssigt slutter skillevæggenes frie, fra armaturen bortvendende kanter sig desuden til indersiden 10 af en armaturen omsluttende ramme.Conveniently, the free walls of the partitions facing away from the luminaire further end up on the inside 10 of a luminaire enclosing frame.

Ifølge yderligere en fordelagtig udførelsesform for opfindelsen har en fra slidsvæggen udgående tværvæg på hver side af skillevæggen en slidsformet gennemføring for tilslutningsledningerne.According to a further advantageous embodiment of the invention, a transverse wall extending from the slit wall on each side of the partition has a slit-shaped passage for the connection lines.

15 Opfindelsen forklares i det følgende nærmere un der henvisning til tegningen, hvor fig. 1 er et snit gennem en ramme med et lysarmatur ifølge opfindelsen, og fig. 2 viser undersiden af armaturdelen.BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in greater detail below with reference to the drawings, in which: FIG. 1 is a section through a frame with a light fixture according to the invention; and FIG. 2 shows the underside of the luminaire part.

20 Fig. 1 viser en over en koblingsdåse 10 i en væg li monteret belysningsarmatur 12 med armaturramme 13 og kuppel 14. I armaturdelen 12 er ved hjælp af en snaplås 15 anbragt en lampeholder 17 for glødelampens 16 lampeholder 17, til hvilken der er ført 25 tilslutningsledninger 18 og 19. Disse er anbragt i tilslutningsorganer henholdsvis 20 og 21 ved soklens 17 tilslutningsende 17a.FIG. 1 shows a lighting fixture 12 mounted over a switch box 10 in a wall luminaire 12 with luminaire frame 13 and dome 14. A lamp holder 17 for the lamp bulb 17 of the incandescent lamp 16 is provided by means of a snap lock 15 and 25 19. These are arranged in connecting means 20 and 21, respectively, at the connecting end 17a of the socket 17.

Armaturdelen 12 er som vist i fig. 2 forsynet med et kasseformet indre rum 22, som afgrænses af 30 sidevægge 23 og 24 samt en tværvæg 25. Rummet 22 deles af to skillevægge 26 i to større afdelinger 27 henholdsvis 28 samt én mindre mellemliggende afdeling 29. Slidsen 30 i tværvæggen 25 fører ind til begge de større afdelinger 27 og 28.The luminaire part 12 is shown in FIG. 2 is provided with a box-shaped inner compartment 22, which is bounded by 30 side walls 23 and 24 and a transverse wall 25. The compartment 22 is divided by two partitions 26 into two larger compartments 27 and 28, respectively, and one smaller intermediate compartment 29. The slit 30 in the transverse wall 25 enters to both major divisions 27 and 28.

35 Yderligere vægge 31 og 32 i armaturdelen 12 definerer et hylsterformet fæste, i hvilket lampeholde- 3Additional walls 31 and 32 of the luminaire portion 12 define a casing-shaped bracket in which the lamp holder 3

ren 17 kan indføres til en låsestilling bag snaplåsen 15, til anlæg mod en flange 33, som omgiver en åbning 33a. Lampeholderen 17 er af standardtype og forsynet med sådanne styreorganer, at den kun kan anbringes i 5 fæstet i én af to drejefaste stillinger (den ene 180° drejet fra den anden). I begge disse drejestillinger slutter begge skillevæggene 26 sig til holderenden 17a på en sådan måde, at tilslutningsorganerne 20, 21 vender mod hver sin af afdelingerne 27 og 28.Clean 17 can be inserted into a locking position behind snap lock 15, for abutment against a flange 33 surrounding an opening 33a. The lamp holder 17 is of a standard type and is provided with such control means that it can only be placed in 5 fixed in one of two pivotal positions (one 180 ° turned from the other). In both of these pivot positions, both partitions 26 join to the retainer end 17a in such a way that the connecting means 20, 21 face each of the sections 27 and 28.

10 Armaturen 12 er endvidere forsynet med et skruehul 34 til fastgørelse på rammen 13, der på sin side er forsynet med ikke-viste fastgørelsesskruer i væggen 11, og en forhøjning 12a; som letter placeringen af de fra dåsen 10 kommende tilslutningslednin-15 ger 18 og 19.The luminaire 12 is further provided with a screw hole 34 for fastening to the frame 13, which in turn is provided with non-shown fastening screws in the wall 11, and an elevation 12a; which facilitates the placement of the connecting lines 18 and 19 coming from the can 10.

Forud for monteringen af rammen 13 over dåsen 10 demonteres armaturdelen 12. Derefter laver man et hul i en i en åbning 13a i rammebundens indsat blød-plastbeslag 35 og nul- og faseledninger 18, hen-20 holdsvis 19 igennem til dåsen 10. Derefter kan rammen 13 skrues fast på væggen 11. Ledningerne 18, 19 afskæres derefter i en passende længde, afisoleres i enderne og føres ind i tilslutningsorganerne 20 henholdsvis 21 i den i armaturdelen 12 monterede gløde-25 lampeholder 17. Nu er armaturdelen 12 klar til at blive monteret i rammen 13, hvilket sker ved at man samtidig tilser, at ledningerne 18, 19 indføres i hver sin slids 30, placerer armaturdelen på dens rette sted i rammen 13 og trækker den til med en ikke vist skrue 30 i skruehullet 34. Ledningerne er nu effektivt adskilt på en strækning fra tilslutningsorganerne 20, 21 og i det mindste til slidserne 30 i termisk sikker afstand fra nævnte tilslutningsorganer. Dette gør det således muligt at anvende sædvanlige installationsledninger, 35 som ellers ikke ville være termisk tilfredsstillende, og som installatøren selv tilslutter direkte i glødelampeholderen .Prior to mounting the frame 13 above the can 10, the luminaire portion 12. is removed from a hole in a soft-plastic bracket 35 and inserted in the opening of the frame bottom and zero and phase leads 18, 19 respectively to the can 10. Then the frame 13 is screwed onto the wall 11. The cables 18, 19 are then cut to a suitable length, stripped at the ends and inserted into the connecting means 20 and 21 respectively of the filament 25 lamp holder 17 mounted in the fixture 12. The fixture portion 12 is now ready to be mounted in the frame 13, which is done by simultaneously ensuring that the wires 18, 19 are inserted into each slot 30, placing the luminaire part in its proper place in the frame 13 and tightening it with a screw 30 not shown in the screw hole 34. The wires are now effectively separated on a stretch from the connecting means 20, 21 and at least to the slots 30 at a thermally safe distance from said connecting means. This makes it possible to use conventional installation wires, which would otherwise not be thermally satisfactory and which the installer himself plugs directly into the incandescent lamp holder.
