Description
Indbvaninaslampe.Indbvaninaslampe.
Opfindelsen angår en indbygningslampe til montering i bygningselementer såsom lofter, hvor indbygningslampen omfatter en lyskilde, som er monteret i et inddækningshus, hvor lyskilden er monteret til en frontpart og udsender lys gennem en frontplade, og hvor der mellem frontparten og frontpladen er en luftspalte, og hvor inddækningshuset er forbundet til en kabeltilslutnings- og/eller transformatorenhed.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a recessed luminaire for mounting in building elements such as ceilings, wherein the recessed luminaire comprises a light source which is mounted in a cover housing, wherein the light source is mounted to a front portion and emits light through a faceplate and wherein there is an air gap between the front portion and the faceplate. wherein the cover housing is connected to a cable connection and / or transformer unit.
Det er kendt at fremstille indbygningslamper som typisk monteres i lofter, hvilket betyder at indbygningshøjden ønskes minimeret.It is known to manufacture recessed lamps which are typically mounted in ceilings, which means that the recessed height is desired to be minimized.
Af den årsag er indbygningslamper ofte to-delte, således at lyskilden er placeret i et inddækningshus, der er adskilt fra en transformatorenhed, som anvendes når lyskildens driftsspænding er lavere lysnettets spænding, hvilket eksempelvis er tilfældet for halogen eller LED baserede lyskilder.For this reason, recessed lamps are often two-part, so that the light source is located in a cover housing separate from a transformer unit which is used when the operating voltage of the light source is lower the voltage of the mains, as is the case for halogen or LED based light sources, for example.
I de hidtil kendte typer indbygningslamper er inddækningshuset og transformatorenheden normalt forbundet med et mekanisk beslag.In the known types of recessed lamps, the cover housing and the transformer unit are usually connected to a mechanical bracket.
Det har imidlertid vist sig at der er nogle ulemper ved den kendte teknik, herunder at nye typer lyskilder såsom halogen eller LED baserede ikke kan anvendes i de hidtil kendte indbygningslamper, idet de udvikler så megen varme, at inddækningshuset opvarmes til en temperatur, der er højere end den, der maksimalt kan tillades for eksempelvis at opnå den nødvendige CE godkendelse af indbygningslamper, der skal sælges i EU.However, it has been found that there are some disadvantages of the prior art, including that new types of light sources such as halogen or LED based cannot be used in the previously known built-in lamps, because they develop so much heat that the cover housing is heated to a temperature that is higher than the maximum allowed, for example, to obtain the necessary CE approval for recessed lamps to be sold in the EU.
Desuden er det en ulempe, at det er relativt bekosteligt at fremstille og montere de mekaniske beslag, som anvendes til at forbinde inddækningshus og kabeltilslutnings- og/eller transformatorenheden. De hidtil anvendte mekaniske beslag er desuden ikke fleksible nok til mange montage situationer.Furthermore, it is a disadvantage that it is relatively expensive to manufacture and assemble the mechanical fittings used to connect the cover housing and the cable connection and / or transformer assembly. Furthermore, the mechanical fittings used so far are not flexible enough for many mounting situations.
Det er derfor et formål med opfindelsen at forbedre teknikken til fremstilling af indbygningslamper.It is therefore an object of the invention to improve the technique of manufacturing recessed lamps.
Opfindelsens formål tilgodeses ved en fremgangsmåde af den i indledningen til krav 1 angivne type, som er karakteristisk ved, at der mellem lyskilden og inddækningshuset er placeret et varmeskjold.The object of the invention is met by a method of the type specified in the preamble of claim 1, which is characterized in that a heat shield is placed between the light source and the cover housing.
På denne måde bliver det således muligt at anvende eksempelvis LED baserede lyskilder, idet varmeskjoldet reducerer opvarmningen af inddækningshuset til et niveau, der kan CE godkendes.In this way, it becomes possible, for example, to use LED-based light sources, since the heat shield reduces the heating of the cover housing to a level that can be CE approved.
Som angivet i krav 5 er det endvidere et særkende ved opfindelsen at inddækningshuset er forbundet til en kabeltilslutnings- og/eller transformatorenhed via et fleksibelt bælte.Further, as claimed in claim 5, it is a feature of the invention that the cover housing is connected to a cable connection and / or transformer unit via a flexible belt.
Hermed opnås at de relativt bekostelige og ufleksible mekaniske beslag kan erstattes af et enkelt, billigt og eftergiveligt bælte eksempelvis fremstillet i gummi.The result is that the relatively expensive and inflexible mechanical fittings can be replaced by a simple, cheap and resilient belt, for example made of rubber.
Øvrige hensigtsmæssige udførelsesformer for indbygningslampen er angivet i kravene 2 til 4 samt 6 til 10.Other suitable embodiments of the recessed lamp are given in claims 2 to 4 and 6 to 10.
Opfindelsen skal herefter nærmere forklares under henvisning til tegningerne, på hvilke:The invention will now be explained in more detail with reference to the drawings, in which:
Fig. 1 viser en foretrukket udførelsesform af indbygningslampen.FIG. 1 shows a preferred embodiment of the recessed lamp.
Fig. 2 viser en delvist adskilt indbygningslampe.FIG. 2 shows a partially separated recessed lamp.

Fig. 4 viser et forstørret udsnit af fig. 3FIG. 4 shows an enlarged section of FIG. 3
Fig. 5 viser et forstørret udsnit af fig. 3.FIG. 5 shows an enlarged section of FIG. Third
På fig. 1 er med 1 betegnet vist en indbygningslampe som er fremstillet i henhold til opfindelsen.In FIG. 1, with a designation 1, is shown a built-in lamp made according to the invention.
Indbygningslampen 1 indeholder en lyskilde 2 som er monteret til en frontpart 16 og som afgiver lys fra en frontplade 3, hvor der er en luftspalte 15 mellem frontparten 16 og frontpladen 3.The recessed lamp 1 contains a light source 2 which is mounted to a front part 16 and emits light from a front plate 3, where there is an air gap 15 between the front part 16 and the front plate 3.
Lyskilden 2 er placeret i et inddækningshus 4, som via et fleksibelt bælte 5 er forbundet til en transformatorenhed 6, som anvendes til transformering af lysnettets spænding til den driftsspændingen for lyskilden 2.The light source 2 is located in a cover housing 4 which is connected via a flexible belt 5 to a transformer unit 6 which is used to transform the voltage of the mains to the operating voltage of the light source 2.
Luftspalten 15 anvendes til luftcirkulation således at varmen fra lyskilden 2 kan ledes væk fra indbygningslampen 1, idet indbygningshuset 4, der omslutter lyskilden 2 bag frontpladen 3, er lufttæt, således at varm luft ikke kan penetrere indbygningshuset og derved opvarme bagvedliggende bygningsdele.The air gap 15 is used for air circulation so that the heat from the light source 2 can be dissipated away from the built-in lamp 1, the housing housing 4 enclosing the light source 2 behind the faceplate 3 being airtight, so that warm air cannot penetrate the housing and thereby heat the underlying building parts.
På fig. 1 ses endvidere at transformatorenden 6 i den viste foretrukne udførelsesform er forbundet med en kabelmonteringsenhed 8 der anvendes til tilkobling til lysnettet.In FIG. 1, it is further seen that, in the preferred embodiment shown, the transformer end 6 is connected to a cable mounting unit 8 used for connection to the mains.
Transformatorenheden 6 og kabelmonteringsenheden 8 er forbundet med et fleksibelt bælte 7.The transformer unit 6 and the cable mounting unit 8 are connected to a flexible belt 7.
Det fleksible bælte 5 såvel som det fleksible bælte 7 kan være fremstillet i et polymert materiale såsom i et gummi-materiale.The flexible belt 5 as well as the flexible belt 7 may be made of a polymeric material such as a rubber material.
Ved at anvende et fleksibelt polymert bælte 5,7 til at forbinde de forskellige enheder som indgår i indbygningslampen 1 opnås at den mekaniske kobling er billig at fremstille, let at montere og minimalt pladskrævende.By using a flexible polymeric belt 5.7 to connect the various units included in the recessed lamp 1, it is achieved that the mechanical coupling is inexpensive to manufacture, easy to assemble and minimally space consuming.
I fig1 ses desuden at inddækningshuset er forsynet med et antal fortrinsvis to befæstigelsesorganer 17, som består af vinklede pladestykker, som kan drejes og bevæges med en skrue, hvorved befæstigelsesorganerne 17 kan anvendes til at fastgøre indbygningslampen 4 til loftet hvori den placeres.In Fig. 1 it is further seen that the cover housing is provided with a number of preferably two fastening means 17, which consist of angled plate pieces which can be rotated and moved with a screw, whereby the fastening means 17 can be used to secure the built-in lamp 4 to the ceiling in which it is placed.
Fig. 2 viser en delvist adskilt indbygningslampe 1 hvor det ses at frontpladen 3 med tilhørende lyskilde 2 og omsluttende varmeskjold 9 befæstes til inddækningshuset 4 ved anvendelse af et antal fortrinsvis 4 friktionselementer som i den viste foretrukket udførelsesform består af bladfjedre 18.FIG. 2 shows a partially separated recessed lamp 1 where it is seen that the front plate 3 with associated light source 2 and enclosing heat shield 9 is attached to the cover housing 4 using a number of preferably 4 friction elements which in the preferred embodiment shown consist of leaf springs 18.
I fig. 3 er vist et snitbillede af den foretrukne udførelsesform af indbygningslampen som er vist i fig. 1.In FIG. 3 is a sectional view of the preferred embodiment of the recessed lamp shown in FIG. First
Af fig. 3 ses at der mellem lyskilden 2 og indbygningshuset 4 er placeret et varmeskjold 9.In FIG. 3 it is seen that a heat shield 9 is located between the light source 2 and the housing 4.
Varmeskjoldet 9 er lufttæt og omslutter lyskilden 2 i retning mod indbygningshuset 4 hvorved opvarmningen af indbygningshuset fra lyskilden 2 reduceres markant i forhold til de hidtil kendte indbygningslamper, som ikke er forsynet med et varmeskjold 9.The heat shield 9 is airtight and encloses the light source 2 in the direction of the housing 4, whereby the heating of the housing from the light source 2 is markedly reduced compared to the previously known built-in lamps which are not provided with a heat shield 9.
Varmeskjoldet 9 omslutter lyskilden 2 således at luftspalten 15 kan skabe luftcirkulation omkring lyskilden 2, og dermed afgive varme til omgivelserne i samme retning som den, hvor lyskilden afgiver lys.The heat shield 9 encloses the light source 2 so that the air gap 15 can create air circulation around the light source 2, thus delivering heat to the surroundings in the same direction as the light source emits light.
Desuden fordeler varmeskjoldet 4 den bagudstrålende varme hvilket reducerer lokale punktopvarmninger af inddækningshuset 4, som kan være kritisk i forbindelse med produktgodkendelse.In addition, the heat shield 4 distributes the backward radiating heat which reduces local point heating of the cover housing 4, which may be critical in connection with product approval.
Forsøg har vist at den ønskede varmespredning optimeres ved anvendelse af aluminium til fremstilling af varmeskjoldet 4.Tests have shown that the desired heat dissipation is optimized using aluminum to produce the heat shield 4.
I en foretrukket udførelsesform kan varmeskjoldet 9, foruden at fungere som termisk isolator mellem lyskilden 2 og indbygningshuset 4, anvendes til at fastholde lyskilden 2.In a preferred embodiment, the heat shield 9, in addition to acting as a thermal insulator between the light source 2 and the housing 4, can be used to hold the light source 2.
Fig. 4 viser et forstørret udsnit A af fig. 3, hvoraf det ses, at toppen af inddækningshuset 4 er forsynet med et varmefordelingslag 13 som fortrinsvis er fremstillet i aluminium samt et termoisolationslag 14, hvilket kan være hensigtsmæssigt for reduktion og fordeling af varmeafgivelsen af opgivelserne.FIG. 4 shows an enlarged section A of FIG. 3, from which it is seen that the top of the cover housing 4 is provided with a heat distribution layer 13 which is preferably made of aluminum as well as a thermoisolation layer 14, which may be suitable for reducing and distributing the heat release of the particulates.
Det fremgår endvidere af fig. 4, at inddækningshuset 4 befæstiges til det fleksible bælte 5 ved anvendelse af monteringsstag 19, som ved opvarmning kan deformeres i toppen og derved sammenholde enhederne.It is furthermore apparent from FIG. 4, the cover housing 4 is fastened to the flexible belt 5 by using mounting bracket 19 which, by heating, can be deformed at the top and thereby compare the units.
I en foretrukket udførelsesform kan varmeskjoldet 4 være udformet, så det indeholder en ventilator, som kan monteres i volumet anført ved 12.In a preferred embodiment, the heat shield 4 may be configured to contain a fan which can be mounted in the volume indicated at 12.
En ventilator kan forbedre luftcirkulationen mellem varmeskjoldet 4 og lyskilden 2 og dermed reducere den indre opvarmning af indbygningslampen 1.A fan can improve the air circulation between the heat shield 4 and the light source 2, thus reducing the internal heating of the recessed lamp 1.
I fig. 5 er vist et forstørret udsnit B fra fig. 3 med en foretrukket udførelsesform af indbygningslampen 1, hvor lyskilden og det delvist omsluttende varmeskjold 9 via aksler 10 er forbundet til forpladen 3 og derved drejes et antal grader for justering af lysretningen.In FIG. 5 is an enlarged section B of FIG. 3, with a preferred embodiment of the recessed lamp 1, where the light source and the partially enclosing heat shield 9 are connected via shafts 10 to the front plate 3, thereby rotating a number of degrees to adjust the light direction.
Akslerne 10 er påvirket af fjedre 11 således at fjederkraften giver en vis friktion, hvilket sikrer, at lyskilden 2 forbliver i den position hvortil den drejes.The shafts 10 are actuated by springs 11 so that the spring force gives some friction, which ensures that the light source 2 remains in the position to which it is rotated.
