    2016-04-27P41601072SEOO/IFG Lighting device TECHNICAL FIELDThis invention relates to a lighting device according to the preamble of claim1. ln particular, the invention relates to a lighting device for a bathroom mirror.
    BACKGROUND OF THE INVENTION Backiighting of bathroom mirrors is known from e.g. US2007/0211452. A lightsource is provided in a support structure behind the mirror glass and the lightis allowed to pass through the glass panel via openings in the reflecting layerprovided onto the glass.
    The sealing of the lighting electronics, which is necessary for use in a humidspace such as a bathroom, is arranged behind the mirror glass inUS2007/0211452 so as to allow exchange of the mirror glass without havingto break the sealing.
    Although devices of the type exemplified in US2007/0211452 generallyprovides for a better lighting than traditional non-backlighting lighting designs,there is a desire for more modern solutions that are adapted to the state-of-the-art electronics and that have even better lighting capabilities.
    SUMMARY OF THE INVENTION An object of this invention is to provide a lighting device for use with e.g.bathroom mirrors that exhibits various improved features compared to knownlighting devices. This object is achieved by the device defined inindependent claim 1. The dependent claims contain advantageous embodiments, further developments and variants of the invention.
    The invention concerns a lighting device for wall mounting, said lightingdevice having an inner side intended to face the wall and an outer sideintended to face away from the wall, wherein the lighting device comprises:an electrical light source; an outer plate having one or several regionsconfigured to be translucent or transparent to light; and a support structureconfigured to hold the light source and the outer plate in place and to allowthe lighting device to be mounted to the wall. The lighting device isconfigured to direct light emitted from the light source in an outwardsdirection through the translucent/transparent regions of the outer plate, andthe outer plate is detachably connectable to the support structure.
    The invention is characterized in that the lighting device further comprises atranslucent/transparent light distribution plate that extends in a plane at aninside of the outer plate when the outer plate is connected to the supportstructure, wherein the light source is arranged at an edge of the lightdistribution plate so as to direct light into the light distribution plate via saidedge, wherein the support structure comprises a first frame elementextending along said edge of the light distribution plate, and wherein the lightsource and the edge of the light distribution plate are arranged in a slotprovided in the frame element.
    Such a design has several advantageous effects. The use of a lightdistribution plate makes it possible to achieve a uniform distribution of lightand since the light source is placed at the side thereof the device can bemade thinner than if the light source is placed behind the mirror glass, i.e.between the glass and the wall. Such a design is also suitable for making useof a LED-strip containing a number of LEDs distributed over the striparranged along the edge of the light distribution plate. A light sourcedistributed in such a way along the edge or, even better, along oppositeedges makes the light distribution even more uniform.
    Light distribution plates are known as such. The light enters the platesideways in the direction of the plane of the plate, distributes in the plate,deflects towards the outer plate, typically a mirror glass panel, and goes in anoutwards direction through the translucent/transparent regions of the outerplate. To improve the light distribution plate”s capability to direct light outthrough its front side towards the outer plate, the bottom/inside of the lightdistribution plate can be provided with e.g. etched lines or printed dots, orparticulates can be added to the plate itself (which usually is made ofPMMA). Some light is directed out through the front side of the lightdistribution plate also without etched lines etc., for instance because ofimpurities present in the PMMA material or because of (slight) density variations in the material.
    The slot arranged in the frame element is advantageous for housing the lightsource and the edge of the light distribution plate and for holding thesecomponents in place. ln addition, this design is advantageous for arranging asealing inside or adjacent to the slot of the frame element for protectionagainst intrusion of water and other material or objects so as to form a safeelectrical enclosure for the light source (such as protection class lP44). Forinstance, a transparent or translucent sealing can be arranged between the light source and the edge of the light distribution plate inside the slot.
    Typically, the outer plate is a mirror glass panel comprising a reflective metallayer that has been removed over some region(s) to allow the light to passthrough. As an alternative or complement to the reflective metal film, theouter plate may be provided with a picture, a painting or similar. Such pictureor painting may contain parts that to some degree allows light to pass andsuch parts may form the one or several regions configured to be translucent or transparent to light. ln an embodiment of the invention the support structure comprises an outerelement connected to the outer plate, wherein the outer element is configured to be detachably connectable to the frame element. This enablesan efficient connection (and disconnection) with high strength and appealingappearance. The outer element may, for instance, be arranged to be inserted into the frame element along its direction of extension. ln an embodiment of the invention the frame element and the outer elementare provided with a connection arrangement comprising a first connectionpart that extends along the frame element and a second connection partarranged on the outer element, wherein the second connection part fits intoor onto the first connection part in such a way that the outer element can beattached to or detached from the frame element by sliding the outer elementalong the frame element. ln an embodiment of the invention the support structure comprises a secondframe element extending along an edge of the light distribution plate oppositeto that of the first frame element, wherein the support structure furthercomprises at least one inner element that connects the first and secondframe elements. Preferably, the inner element is arranged on an inner side ofthe light distribution plate. Preferably, the light distribution plate has an upperand a lower edge, as e.g. a substantially rectangular light distribution plate,wherein the first and second frame elements are arranged at said upper andlower edges. The at least one supporting inner element, preferably at leasttwo, can thus extend vertically between the two frame elements. This way itis possible to provide a support structure with high strength, and havingsubstantially horizontal frame elements makes it more easy to hold the lightdistribution plate in place (since the plate can "rest" on the edge placed in theslot of the lower frame element).
    Preferably, the second frame element is arranged in the same way as thefirst frame element, which for instance means that a further light source isarranged in a slot provided in the second frame element, where the lightsource is arranged to direct light into the light distribution plate via the edge opposite to that of the first frame member. Besides providing for goodsupport of the light distribution plate, this provides for a very uniformdistribution of light over the light distribution plate, due to the arrangement oflight sources at opposite edges. As a consequence, the light is also veryevenly distributed over the outer plate. ln an embodiment of the invention the light distribution plate has asubstantially rectangular shape, wherein the first and second frame elements are arranged along a lower and an upper edge of the light distribution plate. ln an embodiment of the invention the device comprises a sealing configuredto provide an electrical enclosure for the light source. Preferably, the sealingis configured to allow use of the device in bathrooms and similar spaces.lP44 is usually the required protection class for such applications. Althoughthe device may be used in other less humid places with a lower requirementfor electrical sealing, such as in living rooms or hotel foyers, the inventivedevice is particularly suitable for use in bathrooms, kitchens, etc., whichrequire a proper electrical sealing.
    The sealing is arranged in connection to the frame element and the lightdistribution plate so that the outer plate can be attached and detached to thedevice without having to break or even pay attention to the sealing. This wayit is possible to mount the "Chassis" of the device to the wall in a first pre-installation step, i.e. the parts of the support structure holding the lightdistribution plate, the light source and the electronic components forconnecting the light source to a power supply, and install the outer plate in alater stage. For instance, the pre-installation can be carried out by a buildingconstruction company and the particular selection of outer plate design canbe done later by the persons who will live in the house or apartment. Also,the outer plate can easily be exchanged, even in a bathroom application.
    The chassis is preferably designed in such a way as to prevent manipulationof the sealing. The sealing is made in the factory under strict product qualitycontrol and the sealing should not be broken etc. when the chassis producthas left the factory. ln an embodiment of the invention the sealing is translucent/transparent andarranged between the light source and the edge of the light distribution plate.Preferably, the sealing extends along and around the edge of the lightdistribution plate. A conventional sealing is generally non-transparent andcannot be arranged between the light source and the edge of the lightdistribution plate. ln an embodiment of the invention the sealing is arranged inside the slot ofthe frame element. The sealing is thereby covered and protected by the frame element. ln an embodiment of the invention the slot is provided with a space adaptedto the size and outer shape of the sealing so as to keep the sealing in place.This dispenses with the need for adhesives etc. to fix the sealing andprovides for a time-efficient installation of the sealing. Further, this way itbecomes possible to arrange the electronic sealing in the frame element(with the light source arranged below/inside of the sealing) and let the sealingseal against the frame element. This simplifies the structure and themanufacture of the device compared to letting the sealing seal only againstthe light distribution plate.
    Moreover, by carefully designing and manufacturing the space and thesealing with small tolerances so that the sealing fits precisely into the space,a sealing made of a rather stiff material can be used (in contrast to aconventional sealing where a flexible material such as rubber is to besomewhat compressed and thus needs a pressure to provide a good sealingeffect). The possibility to use a stiffer material has the advantages that i) it makes installation of the sealing easier (e.g. in the case where the frameelement is of an extruded profile type where the sealing is to be inserted froman end of the frame), ii) it makes it easier to find a material with suitableoptical properties, and iii) a stiffer material can be used not only for sealingbut also for supporting (part of) the weight of e.g. the light distribution plate. ln an embodiment of the invention the sealing has an H-shaped cross-section, wherein the horizontal part of the H is located between the lightsource and the edge of the light distribution plate. The four end parts of thefour “legs” of the H, as well as the outer sides of the H, are suitable for beingused as sealing surfaces against surfaces inside the frame element.Preferably, the edge of the light distribution plate is arranged onto thehorizontal part of the H, or at least with its edge located close to and directedtowards the horizontal part of the H. One pair of the spaced-apart “legs”projecting from the horizontal part of the H is preferably arranged so as toextend somewhat along opposite sides of the light distribution plate.Accordingly, the edge of the light distribution plate is positioned in a U-shaped part of the H-shaped sealing. ln an alternative example, the sealinghas a U-shaped cross-section, where the edge of the light distribution plate is arranged in the "bottom" of the U. ln an embodiment of the invention the sealing is made of polycarbonate. ln an embodiment of the invention the first frame element has an elongatedshape and has a cross-section that is substantially the same along itslongitudinal axis. Typically, the frame element is an extruded aluminiumprofile. ln an embodiment of the invention an inner side of the first frame element isprovided with an opening configured to receive a fastening element forconnecting the supporting inner element to the frame element. This could bea circular hole configured to receive a screw. ln an extruded profile, the opening extends along the entire frame element. ln such a case the width ofthe elongated opening is configured to receive a screw for fastening the supporting inner element. ln an embodiment of the invention the outer plate and the light distributionplate are substantially parallel to each other, when the outer plate isconnected to the support structure. ln an embodiment of the invention the outer plate, when connected to thesupport structure, substantially covers the light distribution plate. ln an embodiment of the invention the outer plate is made of glass. ln an embodiment of the invention the light distribution plate is made ofpolymethyl methacrylate (PMMA). Preferably, the light distribution plate isconfigured to direct transversally directed light out through its front side towards the outer plate. ln an embodiment of the invention the outer plate has one or several regionsprovided with a layer configured to reflect light directed inwardly towards the outer plate so as to function as a mirror. ln an embodiment of the invention the light source comprises a plurality oflight sources distributed along the edge of the light distribution plate.Preferably, the light source comprises a LED-strip or similar with a plurality ofLEDs (light emitting diodes) distributed along the strip. The strip is preferablya form of elongated printed circuit card with LEDs and connections arrangedin the card. Such circuit cards are stiff and can be inserted from an end of theframe into a channel, slit or similar extending along the frame profile,preferably along a bottom of the slot arranged in the frame profile. ln an embodiment of the invention the lighting device comprises a protectionplate arranged on the inner side of the light distribution plate. A main purposeof the protection plate is simply to protect the inner side of the lightdistribution plate from impacts etc. Another purpose is to reflect light that isdirected inwards. The protection plate can be made of plastics or metal andmay be white to reduce absorption of light. Preferably, the protection plate isarranged adjacent to the light distribution plate with an edge aligned with theedge of the light distribution plate, and with both edges arranged along with each other in the slot provided in the frame element.

    DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION Figure 1 shows, in a perspective view, an embodiment of a lighting device 1mounted onto a wall 40 above a sink 41 in a bathroom 42. ln this example the lighting device 1 is a lighted bathroom mirror.
    Figure 2 shows, in a perspective view, an outer front side of the lightingdevice 1 of figure 1. The outer side is substantially covered by an outer plateor panel 7 that is made of transparent glass and that has a metallic light-reflecting layer provided onto its back (inner) side so as to function as amirror. The outer plate 7 has, in this example, one frame-like region 2 that istransparent to light and a central region 3 functioning as the mirror. That is,only the central region 3 is provided with the metallic light-reflecting layer. Aswill described below, light is directed in an outwards direction through the frame-like region 2 such as to illuminate a person in front of the mirror.
    Various shapes and designs are possible for the transparent and thereflecting regions 2, 3. For instance, one can start out from a mirror panelfully covered with a reflective layer on its backside and blast any regions,pattern, text, logo etc. in the reflective layer so as to remove the reflective layer and make certain regions or a certain pattern etc. transparent.
    Figure 2 further shows a lower and upper outer element 4, 5 forming part of a support structure configured to hold e.g. a light source 10 (see figs. 6 and7) and the outer plate 7 in place and to allow the lighting device 1 to bemounted to the wall 40. The outer elements 4, 5 are connected by gluing tothe outer plate 7, and the outer element 7 is, via the outer elements 4, 5detachably connectable to the support structure (see e.g. figure 5).
    Figure 2 also shows end plates 6 that are screwed into the support structure(on both sides, left and right) and hold the outer plate 7 in place. 11 Figure 3 shows, in a perspective view, an inner rear side of the lightingdevice 1 of figure 1. The main plate intended to face inwards towards the wall40 is a protection plate 8, the purpose of which is mainly to protect a lightdistribution plate 9 arranged adjacent to the protection plate 8 (see fig. 6).The light distribution plate 9 and the protection plate 8 have the same size(but not the same thickness).
    Figure 3 further shows the following parts of the support structure: a lowerand upper frame element 11, 12 and a first and second inner element 13, 14that connect the lower and upper frame elements 11, 12 on the inner side ofthe light distribution plate 9 and the protection plate 8. As will be described inmore detail below, the light distribution plate 9 and the protection plate 8 areattached to the lower and upper frame elements 11, 12, which in turn areconnected and held together by the first and second inner elements 13, 14,which thus hold the device 1 together and provides for connection to the wall40. The lower and upper frame elements 11, 12 extend along opposite edges of the combined protection plate 8 and light distribution plate 9.
    The upper frame element 12 is in figure 3 covered by small cover platesscrewed into the element 12. Similar cover plates may be attached to the lower frame element 11.
    Figure 3 further shows some screws and holes for attaching the innerelements 13, 14 to supporting screws in the wall 40, and also a box 15containing electronic components for connecting the light source 10 to apower outlet and for electronic surveillance of the device 1. Electrical cablesetc. are not shown in the figures. The electronics box 15 is configured toexhibit protection class lP44, as also the cable connections to the box 15 and to the light source 10.
    Figure 4a shows an exploded view of the inner, wall-mounted parts of thelighting device of figures 1-3. To assemble these inner parts of the device 1, 12 the lower and upper frame elements 11, 12 are arranged on the lower andupper parts of light distribution plate 9 and protection plate 8 by inserting alower and an upper edge of these plates 8, 9 into a slot 20 of frame elements11, 12 (see also fig. 6). Thereafter, the inner elements 13, 14 are connectedto the frame elements 11, 12 by screwing into an elongated opening 26 thatextends along each of the frame elements 11, 12 at a backside thereof (seefig. 6).
    The slot 20 contains also the light source 10 and a sealing 22 arranged toprovide an electronic enclosure for the light source and its electricalconnections (see fig. 6). The light source 10 and the sealing 22 are arrangedin the slot 20 before inserting the corresponding edge of the plates 8, 9 intothe slot 20.
    The frame elements 11, 12 are extruded aluminium profiles and exhibitaccordingly a cross section that is the same along the profile.
    The parts of the device 1 shown in figure 4a may be called the chassis of thelighting device 1. This chassis can be pre-fabricated at a production site,which both provides for an efficient manufacture and makes it possible toensure the quality of the chassis in particular with regard to the electronicsealing of the light source 10. The chassis is not intended to be dissembledafter having left the production site. The prefabricated chassis can bemounted to the wall and be electrically connected. The outer plate 7 can be attached to the chassis at a later stage.
    Figure 4b shows an exploded view of an outer component of the lightingdevice of figures 1-3. This outer component comprises the outer plate 7, themirror panel, and the supporting lower and upper outer elements 4, 5 that areglued to the outer plate 7 at a lower and upper edge thereof. Also the lowerand upper outer elements 4, 5 are extruded aluminium profiles and exhibitaccordingly a cross section that is the same along the profile. 13 Figure 5 shows the connection of the outer component of figure 4b to theinner wall-mounted parts of figure 4a. A protrusion 23 that extends alongeach of the outer elements 4, 5 fits into a corresponding opening 24 thatextends along each of the frame elements 11, 12 (see fig. 6) so that the outerplate 7 can be connected to the chassis by inserting the protrusions 23 of theouter elements 4, 5 into the openings 24 of the frame elements 11, 12 andsliding the outer plate 7 (and the outer elements 4, 5) sideways as indicated by the arrows in figure 5. ln a last step, the left end plates 6 are attached.
    To remove the outer plate 7, typically for replacing it for another design orbecause it is broken, the end plates 6 are removed on one side of the device1 followed by sliding the outer plate 7 sideways to disconnect the outerelements 4, 5 from the frame elements 11, 12.
    Figure 6 shows a vertical cross section of the lighting device of figures 1-3,including a magnified view of a lower part of the lighting device 1. The crosssection is taken along the left supporting inner element 14 and thus alsothrough the electronic box 15 (the details inside the box 15 are not shown).
    The magnified view in figure 6 shows a cross section of the lower frameelement 1 and how the various parts of the device 1 are connected to andarranged in the lower frame element 11. The parts, arrangements,connections etc. are similar at the upper frame element 12 (but mirror-inverted). The description below is directed to the lower part of the device 1(including e.g. the lower frame element 11) but holds also for the upper partof the device (including e.g. the upper frame element 12).
    The inner side of the lower frame element 11 (left side in figure 6) is providedwith the elongated opening 26. A screw 27 for holding the inner element 14 is fastened into the elongated opening 26. 14 The light source 10 is in this case a LED strip in the form of an elongatedprinted circuit board that is arranged in an open channel in the bottom of theslot 20 in the lower frame element 11. The LED strip is provided with aplurality of LEDs distributed along the strip (see also fig. 7). The LED stripcan be inserted in the channel from an end of the frame element 11. Afterinsertion the LED strip stays in place by the walls of the channel. The stripLEDs andconnections for connecting the strip to cables in turn connected to the contains conductive tracks for connecting the individual electronic box 15.
    A sealing 22 with an H-shaped cross section is provided in the slot 20 of thelower frame element 11 and provides an electrical enclosure (IP44) for thelight source 10. Thus, all electronic components of the device 1 areconfigured to be used in a bathroom mirror application. The sealing 22extends along the frame element 11. The sealing 22 is arranged so that thecentral horizontal part of the H-shaped sealing 22 is positioned horizontally(when the device 1 is mounted to the wall 40) with a lower side facingdownwards towards the LED strip 10 and un upper side facing the edge ofthe light distribution plate 9 (and the edge of the protection plate 8). Asshown in figure 6, the slot 10 is provided with a space adapted to the sizeand outer shape of the sealing 22 so as to keep the sealing in place. Thesealing 22 seals against the walls and bottom of the slot 20 so as to form theelectrical enclosure for the light source 10 arranged below the sealing 22.(The light source 10 is of course arranged above the sealing 22 in the corresponding slot 20 in the upper frame element 12).
    The light distribution plate 9 (and its protection plate 8) is inserted into theslot 20 so that the edge of the light distribution plate 9 (and the edge of theprotection plate 8) becomes positioned at a distance from the opening of theslot 20. ln this example, the edges of the two plates 8, 9 are placed onto thehorizontal part of the H-shaped sealing 22 between one of pair of "legs" ofthe H-shaped sealing 22.
    The sealing 22, or in this case rather the horizontal part of the H-shapedsealing 22, is thus arranged between the light source 10 and the edge of thelight distribution plate 9. To allow light to pass, the sealing 22 is in thisexample made of transparent polycarbonate. The light source 10 is thusarranged at the edge of the light distribution plate 9 and is capable ofdirecting light into the light distribution plate 9 via its edge.
    When the outer plate 7 is connected to the support structure, i.e. when theouter elements 4, 5 are connected to the corresponding frame elements 4, 5,the transparent light distribution plate 9 extends in a plane at an inside of theouter plate 7.
    When the light source 10 is switched on, light is emitted in a directiontowards the edge of the light distribution plate 9. As indicated by the arrowsin the magnified view of figure 6, the light passes through the transparentsealing 22 (or at least through the part of the sealing 22 arranged betweenthe light source 10 and said edge) and enters sideways into the lightdistribution plate 9, wherein the light is deflected in an outwards directiontowards the outer plate 7. The light becomes evenly distributed in the lightdistribution plate 9, in particular because the light sources are distributedalong opposite edges of the light distribution plate 9, and the light directedtowards the outer plate 7 therefore also becomes evenly distributed.Accordingly, the light passing out through the transparent region 2 of the outer plate 7 is also evenly distributed.
    Figure 6 shows further that, as mentioned in relation to figure 5, each of theouter elements 4, 5 is provided with a protrusion 23 that extends along theouter element 4, 5 and fits into the corresponding opening 24 extendingalong each of the frame elements 11, 12. As shown in figure 6, the outerplate 7, to which the outer elements 4, 5 are glued, can be connected to thecorresponding frame element 11, 12 by inserting the protrusions 23 of the 16 outer elements 4, 5 into the corresponding openings 24 of the frameelements 11, 12 sideways from an end position. The protrusion 23 andreceiving opening 24 are arranged in such a way that when the protrusion 23is fitted into the opening 24, the frame and outer elements cannot beseparated in a direction away from each other (i.e. outwards from the wall 40)but only by a motion sideways in relation to each other (i.e. along the frameand outer elements).
    The frame elements 11, 12 are further proved with a number of openings, thepurpose of which are to prevent too large material thickness, or at least a toolarge variation in thickness, of the frame elements 11, 12. This is related tothe production method (extrusion in this case). lf the thickness of the materialis too large or varies too much, the shape of the element can be affectedduring cooling of the component. Examples of such openings are the roundcentrally located part of the opening 26 and the opening on the underside ofthe lower frame element 11. Also the outer element 4 is provided with such amaterial thickness reducing opening (in the protruding part 23 that fits into the recess 24 of the frame element 11).
    Figure 7 shows a sectional view of a lower corner of the lighting device 1 offigures 1-3. Figure 7 shows, for instance, that the light source 10 comprises aplurality of LEDs distributed along the strip extending along (below) the edgeof the light distribution plate 9). The nearest outer half of the sealing 22 hasbeen removed in figure 7; the inner half end part of the sealing 22 is shown tothe left in figure 7 and a section through the nearest outer half is shown to the right.
    From e.g. figures 4b and 5 it can be seen that the light distribution plate 9 hasa substantially rectangular shape, wherein the first and second frameelements 11, 12 are arranged along a lower and an upper edge of the lightdistribution plate 9. 17 From e.g. figures 5-7 it can be seen that the outer plate 7 and the lightdistribution plate 9 are substantially parallel to each other, when the outerplate 7 is connected to the support structure (i.e. to the frame elements 11,12). lt can also be seen that the outer plate 7, when connected to the supportstructure, substantially covers the light distribution plate 9. ln this example, the outer plate 7 is made of glass and the light distributionplate 9 is made of polymethyl methacrylate (PMMA). The supportingstructure (inner elements, frame elements, outer elements) is made of aluminium.
    The invention is not limited by the embodiments described above but can bemodified in various ways within the scope of the claims. For instance, theouter plate 7 and the light distribution plate 9 do not necessarily have to befully transparent but could be translucent to a certain degree, and the transparency/translucency may vary over the area of the plates.
    Further, it is not necessary to direct light into two opposite edges of the lightdistribution plate 9; in particular for smaller devices (smaller outer plates) itmight be sufficient to provide a light source only at one edge of the plate 9.lrrespectively of the number and type of light source used, the light may bedirected into the light distribution plate 9 by more indirect means than described above, e.g. via mirrors or light guides.
    As an alternative, the protruding part 23 can be arranged on the frameelement 11, 12 and the receiving opening 24 on the outer element, 4, 5. As afurther alternative the outer plate 7 may connected to the support structure byother means, such as by using outer elements configured to be hooked onto the upper frame element 12.
