Abstract

A luminaire trough (50) which is designed to be connected to a light-permeable cover (20) in order to form a closed luminaire housing, has ribs (70, 80) projecting into its interior, which are designed for releasably holding a carrier element (100). are designed for lighting units.

Description

The present invention relates to a lighting pan, which is intended to form a closed luminaire housing together with a translucent cover. Furthermore, the invention relates to a luminaire housing for a luminaire, wherein the luminaire is in particular a so-called wet room luminaire.

Moisture-proof luminaires are luminaires that are used in environments in which u.a. An increased humidity may be present. It may therefore be, for example, work halls or garages and areas that are not completely closed to the outside. In this case, since the intrusion of dirt or dust and especially moisture into the interior of a luminaire should be avoided to avoid damaging the electronic components that are responsible for the light generation, the luminaires must be suitably sealed from the environment , In this context, so-called. Protection classes are defined, which set depending on their class certain requirements for the sealing of the lamp housing.

A closed luminaire housing usually consists of at least two components, on the one hand a responsible for the light output cover and on the other hand to be connected to the cover so-called. Light well. At least the luminaire pan is in this case usually designed pot or trough-like to create a receiving space in which then sealed against the environment, the other components of the lamp, in particular those components that are responsible for the light generation, can be arranged. While for manufacturing reasons, lamp trays are often realized in the form of correspondingly punched and bent sheet metal parts, this possibility for realizing a moisture lamp rather not because such made of sheet metal housing can be sealed only very expensive to the environment. Therefore, lighting trays for wet room lights are preferably made of plastic and are hereby produced in particular by injection molding, since in this way an integrally executed and thus closed lamp tray can be realized.

At the same time, however, a corresponding light well must also be designed such that it allows arranging and fixing the other components in the receiving space. However, such measures often lead to the housing produced by injection molding still needs to be processed in addition to provide the necessary mounting options.

The present invention is therefore based on the object to provide a novel way to realize a light bulb, which can be easily manufactured and opens up the possibility in any case to fix the additional components of the light in the interior in a simple manner.

The object is achieved by a luminaire pan, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The light box according to the invention is characterized in that are provided for releasable support, in particular a support member for light emitting units in the interior of the light bulb protruding ribs. These extend integrally from the corresponding side walls of the luminaire pan, so that they can be made in a simple manner. At the same time, these ribs allow easy insertion and possibly removal of a support element for the lamp units.

According to the invention, therefore, a luminaire trough is proposed, which is designed to be connected to a translucent cover to form a closed luminaire housing, wherein the luminaire trough has in its interior projecting ribs, which are designed for releasable mounting of a support member for lighting units. Preferably, in this case, the ribs are arranged on two opposite side walls of the lamp pan.

According to a preferred embodiment of the present invention, it can be provided here that at least two different types of ribs are present, which each have a latching recesses provided for latching to the carrier element. Here, however, the recesses of the various rib types are designed differently, such that they jointly fix the support member in a predetermined position. In this case, provision may be made, in particular, for the ribs of a first type to fix the carrier element in at least one first direction and for the ribs of the second type to fix the carrier element in a second direction substantially perpendicular to the first direction. The appropriate choice of ribs facilitates the insertion of the support member into the lamp housing, which is then fixed in spite of everything in the desired position.

It may further be provided that at least a part of the ribs has recesses for latching a cable holder. Such elements are, for example, then advantageous if along the lamp housing cables - eg. For a through-wiring - to be stored. Here too, the ribs of the luminaire pan according to the invention are thus deliberately designed such that a correspondingly defined bearing of the cables can be achieved solely by the engagement of corresponding cable holders, without these having to be attached to the luminaire pan in an expensive manner by additional fastening measures.

According to a further advantageous embodiment, it may further be provided that at least a part of the ribs has additional passage openings. These can also be used to lay other elongated components along the lamp housing or to attach additional components to the ribs.

Often have light housing on their outer sides due to appropriate regulations symbols such as warning symbols and the like. These are usually applied to this after production of the lamp pan, for example. In the form of embossing or printing or sticking. In all cases, however, additional steps are required to realize the symbol on the outer surface of the lamp housing.

According to a particularly preferred embodiment, it is therefore provided to make the warning symbol on the outer surface of the lamp pan such that it is formed by a plurality of step-like mutually offset surface sections. Such a symbol, which may represent, for example, a voltage warning lightning bolt, can then be created in an efficient manner in the context of manufacturing the lamp pan by means of injection molding. This special, inventive design of the warning symbol leads to the fact that, despite everything, the luminaire pan after injection molding in a simple manner from the injection mold can be removed from the mold. Thus, the effort to realize a lamp is reduced again overall.

In order to be able to form the desired sealed luminaire housing together with a cover, the luminaire trough according to the invention may preferably have a circumferential sealing channel, wherein a seal is arranged in the bottom area of the sealing channel. In this case, it can be provided, in particular, that an outer wall of the sealing channel has latching recesses facing the channel, which then interact in a corresponding manner with latching projections of the cover. Furthermore, an inner wall of the channel can have recesses lying opposite the latching recesses. This measure, in turn, facilitates the subsequent removal of the trough from the tool after the luminaire trough has been produced by means of injection molding.

In order to supply power to the components inside the luminaire, external power supply cables must be routed inside the luminaire housing. Thus, luminaire trays often have one or more areas which are broken out of the trough to form feedthrough openings. Such areas are also provided in the luminaire trough according to the invention, wherein according to a particularly preferred embodiment at least one of these areas is formed centrally in a bottom surface of the luminaire trough. Usually, such areas are provided on the end surfaces or in the end regions of the bottom surface. In the case of the luminaire trough according to the present invention, corresponding areas for forming feed openings may also be provided at these locations; in addition, however, a corresponding area is now provided centrally or centrally, which provides greater flexibility in supplying the luminaire with power and thus in positioning the luminaire Luminaire opened. The luminaire tub can, for example, consist of PC or PMMA. In the case of the use of PMMA, a translucent design of the lamp pan would result, which can possibly be used to achieve additional lighting effects in the context of a secondary light output.

According to the invention, a luminaire housing is also proposed in particular for a damp-proof luminaire, wherein the housing is formed by a luminaire tub of the type just described as well as a cover to be connected to the luminaire tub. In this case, it may be provided, in particular, that the cover and the tub each consist of the same material. Such, preferably sorted realization of both housing parts made of the same material leads to the advantage that no temperature difference between different housing components is to be feared. This effect could possibly lead to shifts, which can adversely affect the functionality of the seal as well as the locking. However, such problems are avoided in the preferred embodiment in that both housing components are made of the same material and accordingly expand or contract in a similar manner.

In a luminaire according to the invention, which has a luminaire housing of the type just described, may also be preferably provided that in the luminaire housing means for Light generation are arranged. These can be arranged in particular on a device carrier, which is releasably locked to the lamp pan. In this case, the device carrier may have light passage openings, which allow passage of light from a region of the housing, in which the means for generating light are arranged, in a region of the device carrier opposite the means for generating light. This can then be used in the event that the light sump is at least partially translucent, although primarily to emit the light generated by the bulbs on the cover, but to enter a portion of the light in the opposite region of the housing and then over to radiate the housing pan.

In the 1 and 2 are initially two perspective views of a generally with the reference numeral 1 provided wet room light shown, which is therefore intended in particular for use in areas where, inter alia, an increased humidity may be present. The lamp 1 should therefore in particular be designed such that the penetration of dust and / or moisture in the interior of the lamp 1 is avoided. By the sealing measures described in more detail below, the light should 1 then meet the requirements of protection class IP65, ideally IP66 class.

Essential components of the lamp 1 are a so-called light bulb 50 , a cover 20 as well as a detail described below, in the 1 and 2 unrecognizable equipment carrier, in the of the lamp 50 and the cover 20 is enclosed space and carries the responsible for the production of light components. The luminaire housing is thus by the components to be interconnected luminaire trough 50 and cover 20 educated. These enclose an elongated receiving space for the other components of the lamp 1 ,

It is intended that cover 20 and luminaire tub 50 made of the same material. This is a first particularity over previously known solutions, since due to the different requirements so far was rather intended to form the lamp pan of a first material and to form the responsible for the light output cover of a second material. As a rule, materials were used for the luminaire tub, which in particular made it possible to seal the luminaire interior against external influences. The cover, in turn, was made of a material that met the optical requirements for light output.

In the present case, however, it is now envisaged that the luminaire tub 50 and cover 20 sorted of the same material, which may be provided, for example, according to a first preferred embodiment, Polycarbonate (PC) is used for both components. This plastic material can be designed both opaque and opal, in which case for the tub 50 Preferably, an opaque material is selected, while the cover 20 opal is executed. That is, the cover 20 has in this case at least slightly light scattering properties, resulting in a homogeneous, uniform light output.

According to another advantageous variant, it can be provided that both lighting pan 50 as well as cover 20 made of polymethyl methacrylate (PMMA) are formed. It is a material that can be made crystal clear. This choice of material then leads to light not only on the cover 20 can emerge, but also on the also translucent running tub 50 , This can be used to the housing of the lamp 1 overall lightening or over the tub 50 to achieve an indirect light output.

However, in both variants, as already mentioned, there are luminaire troughs 50 and cover 20 from the same materials, which also brings with it the advantage that with temperature fluctuations both housing components 20 . 50 expand or contract in the same way. This means that temperature fluctuations can not lead to a negative impact on the sealing measures described in more detail below. This will seal the luminaire 1 additionally improved against external influences.

Another special feature of the lamp 1 is that apart from the sealing material described below, the sealing of the lamp interior to external influences exclusively by the two housing components (tub 50 and cover 20 ) and both housing components 20 . 50 are designed so that they can be connected to each other without additional aids. Ideally, there is the cover 20 and the lamp tray 50 completely made of a single material (such as polycarbonate or polymethyl methacrylate) without, for example, in the connection area additional flexible materials are used, as is the case with many known solutions. This leads to a simplified production of both housing parts 20 . 50 because these can be produced in a simple manner by injection molding as described below. On the other hand, the renunciation of additional connection and sealing measures requires a special interaction of the two housing components 20 . 50 in the connection area to achieve the desired connection and sealing.

In this connection, the detailed design of the cover will first be described below 20 with the measures provided for the connection to the luminaire trough 50 to be discribed. This should be especially based on the 5 to 9 respectively.

The 5 and 6 initially show the complete light cover 20 in a perspective view, on the one hand from the inside ( 5 ) as well as from the outside ( 6 ). The cover 20 This has an elongated, dome-shaped shape and is smooth on their outer surfaces. Cleaning the surfaces of the luminaire responsible for the light output in the first place 1 This makes it much easier. Also, the risk of accumulation of dirt particles on the surface of the lamp 1 is reduced.

On the inside of the dome shape, however, is the cover 20 over its substantially entire surface with refractive structures, in the illustrated embodiment with longitudinally extending ribs 24 Mistake. These may for example have a prismatic, triangular in cross-sectional shape, to that about the cover 20 emitted light in the desired manner in the transverse direction to influence. However, other prism structures (eg matrix-like) could also be used here. It should be noted, however, that these refractive structures 24 only optically effective if the material of the cover 20 has no or at least only low light-scattering properties. That is, these structures 24 come primarily in the variant to bear in which the cover 20 is formed of PMMA.

The shape of the cover 20 is chosen such that it is designed to be approximately trapezoidal both in a section perpendicular to the longitudinal direction and perpendicular thereto. Here, however, the floor area 21 curved in the areas of the side walls 22 and the end faces 23 above. This shape leads to increased mechanical stability of the cover 20 , avoids sharp edges on the outside of the cover 20 which could adversely affect the light output, and in turn facilitates cleaning of the surfaces responsible for the light output. The floor area 21 can like the representations of the 3 and 4 can be removed slightly concave, whereby the light output can be additionally influenced in the desired manner.

The for latching the cover 20 with the light bulb 50 as well as for the sealing of the lamp housing responsible components can in particular the 7 to 9 be removed.

Here it is first evident that the sloping outward side walls 22 and end faces 23 the cover 20 in a circumferential jetty 26 go over, which is approximately perpendicular to the plane of the bottom surface 21 is aligned and in a sealing channel of the luminaire tub described in more detail below 50 should intervene. This uninterrupted over the entire circumference extending web 26 should then provide in cooperation with a recorded in the sealing channel sealing material for the actual sealing of the lamp interior.

In addition, the cover points 20 but also one from the top edge of the sealing bar 26 right-angled outward splash guard edge 25 on, in particular in 7 is recognizable. In the assembled state of the luminaire housing, this covers the sealing channel of the luminaire tub 50 and thus prevents any influence of spray water or the like which acts directly on the sealing area. The risk of a dynamic pressure acting on the seal is thus avoided. This is a supplementary protective measure which does not prevent the fundamental penetration of moisture into the interior of the luminaire (this is to be achieved through the interaction of the seal and the sealing web 26 be achieved), by which, however, an additional protection of the lamp 1 is achieved.

Also this splash guard edge 25 preferably extends fully over the entire outer circumference of the cover 20 , but is interrupted at individual points. These are those locations where the latching areas 30, which a tool-free locking of the cover 20 with the light bulb 50 allow, are provided. Several of these rest areas 30 are evenly distributed over the circumference of the cover 20 provided, wherein a single latching area in the 8th and 9 is shown enlarged.

The rest area 30 In this case, in particular, one knows on the outer circumference of the sealing web 26 provided, web-like locking projection 31 on, at its bottom by two trapezoidal supporting webs 32 is supported. This latching projection 31 with the support webs 32 should then be in a corresponding recess of the lighting pan 50 intervention. However, at a later date to release the locking between cover again 20 and luminaire tub 50 to allow, is above the locking projection 31 in the splash guard 25 a rectangular opening 28 provided, via which an access to the locking projection 31 is possible. Here is an interruption of the splash guard edge 25 before that the subsequent release of the catch between cover 20 and luminaire tub 50 allows.

At the same time, of course, there is a risk that this interruption in the splash guard 25 Water penetrates into the sealing area of the luminaire housing. To prevent this, there are two additional vertical bars 29 provided, which extends from the end portions of the opening 28 down to the locking projection 31 extend. These bridges 29 , which has a smaller depth than the locking projection 31 have, are in the latched state of the lamp housing on both sides of the locking recess described in more detail below on the wall of the lamp cover 50 on, so that splash water in the area above the locking projection 31 can penetrate here, but then will not penetrate further into the connection area, since this area completely through the corresponding wall of the housing pan and through the webs 29 and the locking projection 31 is enclosed. The bridges 29 and the locking projection 31 bridge accordingly the opening 28 Splash guard edge, so that a total of all-round splash guard in the area of the connection between the cover 20 and tub 50 is achieved.

Furthermore, on the inside of the sealing edge 26 on both sides of the resting areas 30 one more jetty each 27 intended. These additional bars 27 support the interaction of the latching areas 30 the cover 20 with corresponding locking means of the tub 50 , which will be explained in more detail below.

In addition to mention is, moreover, that the circumferential splash guard edge 25 In addition to their actual, described above function of protection against water spray also serves as a stacking aid. That is, several lights covers 20 The illustrated type can be stacked on each other in a simple manner, with a cover 20 then with the lower edge of the sealing web 26 on the splash guard edge 25 the cover underneath 20 rests. This facilitates storage and transport of the cover 20 , Furthermore, the shape of the cover is chosen such that it can be produced in a simple manner as part of an injection molding as already mentioned.

The design of the light bulb 50 can the 10 to 17 and 19 will be taken, in the following, first for the sealing connection of the tub 50 with the cover 20 essential features should be explained.

The light bulb 50 This case initially has a pot-shaped or trough-like configuration and corresponds in terms of their dimensions substantially the dimensions of the cover 20 , At the bottom surface 51 as well as the front sides 53 can be realized here later cable feeds, via which the electronic components inside the lamp 1 be connected to external power supply lines.

The two side walls 52 and the end walls 53 the luminaire tub 50 in this case include one of the cover 20 facing opening, wherein according to the enlarged view of 13 the luminaire tub 50 in this area the opening is double-walled. Strictly speaking, according to the sectional view according to 14 the side and end walls 52 . 53 first by a first bridge 62 extended. Further, the tub 50 through a second, angled running bridge 61 laterally expanded, this second outer web 61 then substantially parallel to the inner web 62 runs, but this slightly overshadowed. In this way, a completely the opening of the tub 50 comprehensive sealing channel 60 formed, whose outer wall through the bridge 61 and its inner wall through the bridge 62 is formed and in its bottom area a seal 63 having. Preferably, this seal is after manufacture of the tub 50 in the channel 60 foamed or introduced by alternative methods and then forms a contact surface for the lower edge of the sealing web 26 the cover 20 , This reaches over the entire circumference of the canal 60 in this one and effected by their attachment to the seal 63 in that the interior of the luminaire housing is protected against dust and / or moisture.

A reliable holder of the cover 20 at the light trough 50 is by resting areas 65 achieved, which increases in the representation according to 13 are recognizable. These resting areas 65 are formed by the outer web 61 a thickening 66 that faces the interior of the sealing channel 60 is facing and a detent recess or recess 67 having. This recess 67 However, only penetrates the thickening 66 but not the entire outer bridge 61 , The housing of the tub 50 is therefore also closed in this area to the outside.

The positioning of the latching areas 65 corresponds to the arrangement of the previously described locking areas 30 the cover 20 , When assembling the light bulb 50 with the cover 20 So grab the locking projections 31 in the associated recesses 67 one. The at the bottom of the locking projections 31 provided angled executed support webs 32 in this case form a run-on slope when placing the cover 20 on the tub 50 a lateral emigration of the outer bar 61 cause. This will be a joining between tub 50 and cover 20 facilitated.

After the cover 20 then with the sealing bar 26 sufficiently in the sealing channel 60 was introduced, engage the locking projections 31 and footbridges 32 completely in the corresponding recesses 67 the luminaire tub 50 one and the outer dock 61 can move back to the original position. This provides a reliable and stable support between cover 20 and tub 50 guaranteed, wherein the dimensions of the responsible for the locking components as already mentioned are chosen such that the lower edge of the sealing web 26 the cover 20 in abutment against the bottom of the canal 60 provided seal 63 passes and thereby the desired protection of the interior of the lamp housing is achieved.

As further based on 14 can be seen, is in this assembled state then the circumferential splash guard 25 the cover 20 on the face of the outer bridge 61 in order to ensure, in addition to the internal seal, the splash guard already described and to prevent the penetration of larger particles into the area of the seal. Openings exist only through the recesses 28 the splash guard edge 25 in the range of individual locks. These openings are required to at a later date, a release of the catch between the tub 50 and cover 20 to enable. However, the rooms are then as already mentioned by the lateral webs 29 from the inside to the outer bridge 61 the tub 50 abut, as well as by the locking projection 31 enclosed. In this area entering liquid or dirt particles can not easily into the sealing channel 60 reach.

This defined interaction between the latching areas 30 the cover 20 and the rest areas 65 the tub is further supported by the fact that on the inner circumference of the sealing edge 26 provided ridges 27 in the assembled state at the channel 60 facing side of the inner web 62 the tub 50 issue. That is, the components of the cover responsible for latching and sealing 20 be supported by the additional support using the bars 27 defined in a certain position with respect to the cooperating elements of the tub 50 held.

A release of the catch between cover 20 and luminaire tub 50 then done by having over the opening 28 of the Splash guard edge 25 a tool, such as a flat-head screwdriver is inserted in the region of the latch. By turning this tool or screwdriver can then locally the outer web 61 the tub 50 be bent outwards, so that the locking projection 31 the recess 67 can leave. In this way, so in a very simple and intuitive way, the locking between cover 20 and luminaire tub 50 be solved again. As already mentioned, this is only possible with the help of an appropriate tool, which is usually available at any time. The webs prevent this 29 and the locking projection 31 Also, when inserting the tool this inadvertently seals 63 touched and possibly damaged.

Overall, in this way, in a simple way, a reliable sealing connection between cover 20 and luminaire tub 50 can be achieved, however, if necessary, can be solved without problems again. It is - as in 13 recognizable - provided that the latching recess 67 opposite the inner jetty 62 an opening or recess 68 having. This is indeed for the later use of the light bulb 50 and also for the interaction with the cover 20 not relevant, but it facilitates the manufacture of the tub 50 by injection molding. Through the recess 67 corresponding opening 68 Namely, a demolding of the lamp pan 50 much easier after injection molding from the corresponding injection molding tool.

Other special features of the luminaire tub 50 relate to the possibilities for supplying external power supply lines and measures that allow the arrangement of components for generating light within the luminaire housing. These properties will be explained in more detail below.

With regard to the possibility of supplying external power supply lines are on the lights 50 several possibilities for forming a feed opening provided. These are areas 54 . 55 and 56 After making the tub 50 are initially closed, but - in the present case - have annular material weakening, which allow the breaking or removal of circular housing sections. In this way then feed openings can be created, can be passed through the cable into the lights inside. These openings can then be sealed by appropriate additional measures such as spouts or the like.

A special feature of the illustrated luminaire tub 50 is now that, as is usual, the areas for forming supply openings exclusively in the end regions of the luminaire pan 50 are provided but beyond a central cable feed is also possible. In the illustrated tub 50 are therefore corresponding areas 54 with material weakenings initially centrally in the bottom surface 51 the tub 50 intended. In addition, there are additional areas 55 and 56 in the end areas of the floor area 51 as well as the front surfaces 53 educated. Depending on the type of installation of the lamp or its field of application, therefore, the supply of an external power supply cable can be adapted in a flexible manner.

Furthermore, at the end regions of the bottom surface 51 two mutually parallel suspension channels 57 educated. These allow the intervention of, for example, a clamp, with a suspension rope for suspending the lamp 1 connected is. Such brackets are already known and allow in a simple way a suspension or pendulum suspension of a lamp 1 , In the present case, the length of the channels 57 in which the arms of the suspension bracket are then to engage, dimensioned such that a certain clearance for the positioning of the suspension bracket remains. This also makes the flexibility in terms of the arrangement of the lamp 1 elevated.

The just mentioned suspension channels 57 can also fulfill another function. Because that's the channels 57 enclosing areas of the housing form linear surface sections, which in particular also on the curved configuration executed the other outside of the lamp pan 50 survive, these areas can also be used as a support or storage areas, which in turn a simple stacking of the same lighting trays 50 is possible. As well as in connection with the cover 20 This therefore leads to a simplified storage and improved transport of the tub 50 to the place of final luminaire assembly.

Other special features of the luminaire tub 50 relate to the design of the interior. It can be seen in particular that along the inner walls of the two side surfaces 52 the tub 50 spread ribs 70 . 80 are positioned. These serve on the one hand to increase the stability of the tub 50 , but especially the tool-free arrangement and attachment of other lighting components.

In this case, two different types of ribs are provided according to the illustrated embodiment, which are designed differently. In the illustrated embodiment are on one side of the tub 50 two ribs of the first type 70 and four ribs of the second type 80 intended. The ribs of the first type 70 , which are positioned longitudinally at the second and fifth positions in the present case, will be explained first below. Of course, it would also be conceivable to vary the arrangement and the number of different types of ribs.

The shape of a rib of the first type 70 is in particular in 12 as well as in 15 recognizable. This initially has a first lower portion 71, which - due to the curved outer shape of the tub 50 - Has approximately the shape of a quarter-ellipse and as shown with a vertical first edge 72 and a horizontal second flank 73 is provided. From this first section 71 is separated above the horizontal flank 73 another rib section 74 formed, which is executed approximately in the form of a right triangle, however, wherein the hypotenuse is angled. Together with the top edge 73 of the first rib section 71 - And the side wall of the housing - closes the second rib section 74 a recess 75 a, which serves the holder of the device carrier described in more detail below. At her to the center of the light sink 50 facing the end here has the horizontal edge 73 Furthermore, a slight elevation, through which the recess 75 is limited laterally.

The lower rib section 71 points in the area of the vertical edge 72 In addition, an approximately triangular further recess 76 on. This allows according to the representation according to 15 the latching of an in 16 individually illustrated cable holder 90 , This - formed for example - plastic - holder 90 is basically about C-shaped with a central leg 91 , the side in two inclined side legs 92 passes, which at its outer end in turn parallel to the central leg 91 extending end region 93 exhibit. In this end area is in each case a Einschlitzung 94 provided so that in the recess 76 the rib 70 latched end portion 93 the lower portion of the rib 70 embraces. This cross-like mesh of rib 70 and wire holder 90 causes this in the in 15 fixed position shown. Because the wire holder 90 is symmetrical and with the corresponding opposite rib 70 the tub 50 cooperates in the same way, this can in a simple manner in the illustrated arrangement in the light well 50 be locked. Feet formed on the underside of the central area 91 95 support the wire holder 90 on the bottom surface of the tub 50 from. Between this floor surface and the wire holder 90 In this case, cables can be routed through several in the tub 50 Fixed wire holders are stored so that they are along the bottom surface of the tub 50 run and not affect the further arrangement of additional components in the luminaire housing.

In the illustrated configuration, the corresponding recesses are 76 for holding the wire holder 90 at the ribs of the first type 70 intended. Of course, corresponding recesses could, however, also be provided additionally or alternatively in the subsequently described ribs of the second type 80. The number of wire holders to be used 90 This can optionally be increased, which depends on the length of the lamp 1 makes sense.

A release of the latch between wire holder 90 and luminaire tub 50 can be achieved in a simple manner that on the central area 91 of the owner 90 pressed or dragged on this area. Due to the flexibility here are the end areas 93 of the wire holder 90 pulled slightly inwards, allowing the latching with the corresponding rib 70 is solved.

Furthermore, it is provided that the ribs of the first type 70 laterally offset to the recess 76 a passage opening 78 exhibit. This may optionally be used to carry additional cables or lines, if desired. Again, that such an opening 78 optionally also in the ribs of the second type 80 could be provided.

The shape of the ribs of the second type 80 can also 12 be removed. These consist primarily of a lower section 81 that has a straight vertical edge 82 having. As mentioned earlier, this lower rib section could 81 Recesses or openings corresponding to the recess 76 or the opening 77 the ribs of the first type 70 be provided.

The upper end of this lower rib area 81 is with a triangle-like projection 83 provided, in turn, with the side wall of the tub 50 - A recess 84 limited. In contrast to the recess 75 However, the first rib 70 here is the recess 84 not limited to the top, since here the rib 80 only through a narrow bridge 85 is continued.

More ribs 88 are also provided on the front end portions of the lamp cover 50. These ribs facing the interior 88 (please refer 11 ), however, extend only over the height of the inner web 62 of the sealing channel 60 and are perpendicular to those on the long sides of the tub 50 arranged ribs of the first and second type 70 respectively. 80 oriented. Among other things, they also support the stacking of several similar lighting trays 50 ,

The function of the previously explained ribs 70 . 80 and 88 in connection with the attachment of the device carrier will be explained below. Previously, however, based on the 17 and 18 yet another special feature of the luminaire tub 50 described. This has on the outside at least one in 17 recognizable warning symbol 250 with a flash warning of voltage in the present case 251 on. Of course, there are of course various possibilities, this warning symbol 250 after production of the luminaire tub 50 to attach to the outside. For example, a corresponding embossing of this symbol would be conceivable 250 or, of course, gluing or printing on the luminaire tub 50 , In the present case, however, it is provided that the symbol in the context of the manufacture of the tub 50 created simultaneously during injection molding.

For this purpose, a special slide used in the injection molding tool is provided, which in 18 shown and with the reference numeral 300 is provided. The fact is used that the illustrated triangular symbol 250 with the lightning contained in it 251 by using a tool area with surface areas 301 . 302 and 303 can be realized, which are executed steppedly offset from each other. At the first surface area 301 , which forms a first part of the interior of the triangle, so closes the second surface area 302 on, the shape of the lightning 251 and opposite to the first area 301 is slightly increased. The triangle is finally completed by the area area 303 which in turn increases to the second area 302 is executed. This special embodiment of the slider 300 As a result, during the injection molding process, the symbol 250 - With then corresponding stepwise offset surface areas - directly on the outside of the lamp cover 50 can be applied, despite all, however, a subsequent demolding of the tub 50 is easily possible. In this way, so the goal can be achieved in a very simple and elegant way, the lights 50 exclusively by injection molding and to avoid subsequent additional steps.

The third essential component of the moisture-proof luminaire 1 is the already mentioned equipment carrier 100 who first in the 20 and 21 is shown. It is an elongated sheet metal part, at which the responsible for the production of light components of the lamp 1 to be mounted. A central, plate-shaped area 101 This is elongated and slightly shorter than the actual length of the lamp 1 , On both sides of the plate-shaped area 101 points the gear tray 100 profiled side legs 102 on that in their end areas 103 Are bent in a U-shape.

The configuration of these profiles or the side legs 102 For example, the representation in 24 be removed. It allows latching with the luminaire pan 50 , In this case, then in the locked state, the in 19 recognizable arrangement results. Visible is how the U-shaped bent end portions 103 the side leg 102 of the device carrier 100 with the recesses 75 and 84 the ribs 70 respectively. 80 interact. In particular, it can be seen that the second upper rib section 74 the rib of the first type 70 a limit stop for the end areas 103 in a direction perpendicular to the plane of the opening of the housing pan 50 forms. The projections 83 the ribs of the second type 80 in turn, form a lateral boundary for the side legs 102. Both rib types 70 . 80 So fix the side legs 102 primarily in one direction each, with both directions substantially perpendicular to each other, so that the equipment carrier 100 overall in the desired position on the housing pan 50 is fixed. The shaping of the corresponding projections or ribs in this case facilitate the insertion of the U-shaped bent and thus having a certain flexibility end region 103 in the recesses 75 . 84 the ribs 70 . 80 , allowing easy insertion of the device carrier 100 in the housing pan 50 is possible. However, this locking is also turn solvable, provided for maintenance, a replacement or removal of the device carrier 100 is desired.

The equipment carrier 100 serves both the holder of the responsible for the generation of light bulbs, in the present case a plurality of LED boards 130 and opposite the positioning of another, for the power supply of the LED boards 130 responsible components. These are appropriate operating devices 140 . 141 and terminals 142 . 143 , Which are then connected via cables not shown with the guided into the interior of the lamp power supply lines or from the operating devices 140 . 141 to the LED boards 130 to lead.

Both the LED boards 130 as well as the components responsible for the power supply 140 to 143 So be through the equipment carrier 100 held, with the components on both sides of the plate-shaped area 101 are positioned. It is provided that on that side of the plate-shaped area 101 on which the LED boards 130 be arranged, frustoconical spacers 110 are formed. These spacers 110 form increased contact surfaces for the LED boards 130 so that these - such as in the 24 and 25 recognizable - have a certain distance h to the surface of the plate-shaped portion 101.

This illustrated spaced arrangement of the LED boards 130 brings several advantages.

Firstly, there is only a very weak direct thermal coupling between the LED boards 130 and the operating devices 140 . 141 in front. Both components - ie LED boards 130 and operating devices 140 . 141 - generate during operation of the luminaire 1 Heat, which in the case of excessive thermal coupling would risk that the heat is transferred to the other component and ultimately be too high, unsuitable for operation temperatures that could possibly lead to damage. The spaced arrangement using the spacers 110 now leads as far as possible to a thermal decoupling between the components, so that this danger is avoided.

Another advantage is that attachment measures for example for the LED boards 130 not to interference with the arrangement of the other components on the opposite side of the equipment carrier 100 to lead. As in particular the representation of 25 can be removed, is provided, the LED boards 130 with the equipment carrier 100 to screw. The spacers 110 each have their upper, flat contact area 111 Holes or general openings 112 on, passing a screw 115 enable. This screw 115 would be without the spacers 110 the plate-shaped area 101 of the device carrier 100 penetrate and survive on the opposite side. Here they would then possibly the arrangement of the control gear 140 . 141 or the like, which is due to the inventive use of the spacers 110 now no longer a problem. In the same way leads the fixing of the terminals 142 . 143 with corresponding locking pins which the plate-shaped area 101 of the device carrier 100, not to affect the arrangement of the LED boards 130. The available area of the plate-shaped area 101 can therefore be used efficiently for the arrangement of components for light generation.

The spacers 110 are preferably an integral part of the device carrier 100. This is generally formed by a corresponding stamped and formed sheet metal part, in which case the spacers 110 be formed by punching and stamping of the corresponding area. Ideally, the spacers 110 are, as already mentioned, frustoconical with a flat bearing surface. They are also designed curved in two mutually perpendicular planes, whereby their stability is increased, so that the LED boards 130 be stored reliably and stably. Stable storage of the boards 130 This is also supported by the fact that the spacers 110 as in particular in 21 recognizable in the longitudinal direction of the device carrier 100 are positioned alternately offset from one another. A single board 130 should be on at least three spacers 110 rest, whereby a defined storage is achieved. This could be the spacers 110 Of course, alternatively or in addition to the opposite side of the device carrier 100 be provided and accordingly one of the plate-shaped area 101 spaced arrangement of the operating devices 140 . 141 enable.

Fixing the boards 130 on the equipment carrier 100 takes place as already mentioned preferably by means of screwing, wherein the board 130 on at least three spacers 110 outsourced. It is preferably provided that the board 130 - Seen in the longitudinal direction - is fixed centrally, is mounted at the two end portions with a certain play. This can be realized, for example, by virtue of the fact that the circuit board 130 has a circular hole for screwing in the center, whereas oblong holes are provided on the end regions. In the same way, however, the sequence of slot - hole - slot can also at the openings 112 in the bearing surfaces 11 the spacer 110 be provided. By this measure, different longitudinal expansions due to the different types of material can be collected, although the board 130 due to the central fixation basically in the desired position with respect to the device carrier 100 is positioned.

When mounting the lamp 1 So it is envisaged that first of the equipment carrier 100 equipped with the components responsible for the generation of light. It then results in the 22 and 23 identifiable configuration, whereby still a wiring between operating device 140 and the LED board 130 is to perform. Since both components are positioned on opposite sides of the device carrier 100, So must the connection cable over a border area of the equipment carrier 100 from one side to the other side. For this it is provided that - as in 21 recognizable - in the front end area of the device carrier 100 a recess 116 is trained. This is the operating device 140 with the LED board 130 Connecting - not shown in the figures - cable should hereby through this recess 116 be guided, wherein the configuration of the recess of a 116 and the arrangement of the LED board 130 chosen such that the board 130 with its front end region already in the region of the recess 116 protrudes. This is to avoid that from one side to the other side of the device carrier 100 guided cables on the peripheral region of the recess 116 immediately applied and, where appropriate, during the manufacture of the device carrier 100 resulting burrs or sharp edges damage to the insulation of the cable takes place. Of course, the shape of the recess could also be otherwise chosen to achieve this purpose. Basically, however, it is desired that the cable is not in contact with sharp edges of the equipment carrier 100 arrives.

The equipment carrier 100 As already mentioned, it is preferably produced as part of a stamping / embossing process, this being done in one operation. This procedure has the advantage that the individual elements of the device carrier 100 So the spacers 110 , Openings, latching openings and the like. In a very precise manner aligned and positioned. This opens up the possibility of the equipment carrier 100 automated to equip eg with the help of a robot, where appropriate provided index openings, which set used for mounting reference positions, simultaneously with the other elements during manufacture in the equipment rack 100 can be introduced.

The corresponding equipped and wired equipment rack 100 is then in the housing tray 50 used and there in the manner described above with the help of ribs 70 and 80 latched or snapped. The frontal ribs 88 the tub 50 in this case form a centering or guide, so that a correspondingly suitable positioning of the device carrier 100 in the housing of the lamp 1 is relieved.

As already mentioned, it is provided in a special variant for the luminaire housing that not only the cover 20 but also the housing tub 50 translucent designed to achieve a secondary light output here. The light used for this purpose should also be from the LEDs 131 the LED boards 130 Thus, so that it is necessary that a light transmission is made possible in the housing area in which the operating equipment 140 . 141 are arranged. This is made possible in the case illustrated by the fact that the plate-shaped region 101 has light passage openings on both longitudinal sides 117 having. The oval in the present case (other forms would of course also conceivable) executed and preferably punched out light passage openings 117 These are located laterally to the areas where the LED boards or the operating devices 140 . 141 be positioned and should not be obscured by these components. Stray light or on the inside of the cover 20 reflected light can then pass through these light openings 117 in the cover 20 enter the remote area of the lamp housing and here on the translucent executed housing tray 50 be delivered. To increase the efficiency of the use of the LED boards 130 generated light is the device carrier 100 preferably designed reflective. For this purpose, it can either consist of a reflective material or be correspondingly reflective coated or painted.

Finally, the equipment carrier 110 also be used to hold a so-called. Primary optics, before the actual light output through the cover 20 the light 1 that from the LED boards 130 to influence generated light. The use of a corresponding primary optics 150 that in the 26 to 29 is shown is particularly advantageous if for the cover 20 the light 1 a material is chosen which is not very light-scattering. Without the use of a light-scattering primary optics, the LEDs would then be in this case 131 the LED boards 130 to recognize as a single point-shaped light sources, which is usually due to the desire for a uniform or homogeneous light output of disadvantage. The illustrated primary optics is thus provided in particular for the case that the cover 20 PMMA, although it could of course also be used in the variant in which the cover 20 Made of PC.

In such a case, it is then provided that in the 26 to 29 illustrated primary optics 150 on the equipment carrier 100 to fix. This primary optics 150 consists of a light-scattering material (for example PC), which initially causes a diffuse scattering of the light. The basic form of primary optics 150 This corresponds approximately to that of the lamp cover 20 , Also, the primary optics 150 is so elongated and dome-shaped, so they the LED boards 130 can spread over. At the front end of primary optics 150 are on both sides locking projections 155 intended. These are located on each downwardly projecting webs 156 the optics 150 and are sized so that they from the outside in corresponding locking openings 120 of the device carrier 100 intervention. These detent openings 120 are in the side legs 102 of the device carrier 100 educated.

The bridges 156 the primary optics 150 So overlap laterally the plate-shaped area 101 of the device carrier 100 so that the latching projections 155 from the outside into the recesses 120 can intervene. Over the wider circumference, the primary optic lies on the surface of the plate-shaped area 101 of the device carrier 100 and engages in this case both the LED boards 130 as well as the light passage openings 117 , An unwanted, not by primary optics 150 influenced light emission is prevented in this way. However, this may possibly be the peripheral form of the primary optics 150 be chosen such that a smaller, for example, a corner region of the plate-shaped area 101 of the device carrier 100 remains free, so not from the primary optics 150 is covered. In this area, for example, a status LED can be positioned, which indicates the operating status of the lamp 1 signaled. To improve the visibility of such a status LED, it is advantageous if their light is not mixed as possible with the light of the actual LEDs 131, so not by the primary optics 150 what is guaranteed by the measure referred to.

For releasing the locking between the device carrier 100 and primary optics 150 only need the webs 156 be bent laterally so that the locking projections 155 the recesses 120 being able to leave. An assembly consisting of equipment carrier 100 and thus locked primary optics 150 is in 29 shown. This assembly can then in the whole and thus in a simple manner in the manner described above in the light bulb 50 be used. The primary optics 150 is not in the area of the U-shaped end areas 103 the side leg 102 so that the latching of the device carrier 100 with the tub 50 is not affected.

Finally, there is an advantageous feature of the primary optics 150 in the illustrated embodiment is that these seen in the longitudinal direction by corresponding ribs 157 , which grooves from the outside 158 in the radiating surface of the optics 150 form into successive segments 159 is divided. That by the primary optics 150 So influenced light exists before going through the actual cover 20 the light 1 is made, from individual sub-bundles, the respective segments 159 the primary optics 150 correspond.

In the case of a uniform light output over the entire length of the device carrier 100 away, this initially only leads to an interesting lighting effect is achieved because the light is easily perceptible subdivided into individual clusters. Alternatively, the segmental subdivision of the primary optics 150 However, also be used to actually about individual longitudinal sections of the lamp 1 to give away different light. As a result, for example, there is the possibility not only one of the lamp 1 assigned area to illuminate, so to lighten, but it could also be conveyed in this way, information or advice. A corresponding control of the LED boards 130 So it could then be used, one over the different segments 159 to generate timed light output, for example, a along the light 1 moving running light is generated, which signals a preferred direction (for example, a rescue route or the like). Also could be a light output in different colors across the individual segments 159 be made, which is then used for example in the sense of a parking lot lighting, to represent whether a lying below the light parking lot is occupied or available.

Overall, therefore, different lighting effects can be achieved with the aid of the illustrated luminaire. The luminaire is characterized in particular by the fact that the various components can be manufactured in a simple manner and mounted accordingly.
