DEVICE SUPPORT FOR LIGHT

The present invention relates to a device carrier for a luminaire, which is intended to carry both light-emitting units as well as the power supply of the lighting units provided operating devices. Furthermore, the present invention relates to a so-called light engine for use in a luminaire.

As a light engine usually that structural unit of a lamp is called, which is responsible for the generation of the light emitted by the lamp light. This unit thus includes, in particular, initially the necessary for the actual light generation bulbs, but possibly also additional components that are responsible for the power supply of the bulbs. Often, the bulbs are also assigned a so-called primary optics, which makes a first influence on the light generated by the bulbs.

While previously used as bulbs, for example, light bulbs or fluorescent lamps, which could be easily replaced by the consumer in the event of a defect, have now prevailed in the lighting technology bulbs on a semiconductor basis. In this case, the bulbs are then often formed by LED boards, in which one or more LEDs on a plate-shaped support, the board, are positioned. In comparison to the above-mentioned classic light sources, however, an exchange of individual LED boards is generally not easy to perform, which is why it is usually intended to position the LED boards on a so-called equipment carrier, which then with the boards as a unit in a lamp is arranged. It is often desirable for security reasons that the end user does not get access to the LED boards to avoid accidental touching of the LEDs or the current-carrying lines of the LED boards.

As a rule, LEDs can not be supplied directly with the supply voltage provided by the general power supply, a device is usually required to operate such bulbs, which converts the lamp externally supplied supply voltage into a suitable operating voltage for the LEDs. This operating device can be positioned separately from the bulbs within the luminaire and then connected to the bulbs via a flexible cable connection. To simplify the installation of the lamp and possibly later carried out maintenance measures, however, it would be advantageous if a lamp and the operating device comprehensive unit is present, which can be arranged and replaced in a single assembly step in the lamp. This means that ideally the operating device should also be positioned on the device carrier. However, it should be noted that both components, on the one hand bulbs and on the other hand operating device, generate heat during operation of the lamp, too high a thermal load on the LEDs and the operating device should be avoided.

The present invention is therefore based on the task to provide a device carrier for a lamp available, which is suitable both for holding the lamp and at least one operating device for the lamps, but in which a mutual negative thermal impairment of these components is avoided. Furthermore, the arrangement of both components on the equipment carrier should not lead to an increased space requirement.

The object is achieved by a device carrier for a lamp having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The device carrier according to the invention is formed by a sheet metal part, which has at least one plate-shaped area. This is used according to the invention, to both

Sides of the device carrier to position the components responsible for the light generation. That is, on one side of the device carrier or the plate-shaped area, the arrangement of the lamp units should be made, the opposite side is used for positioning of the operating device. In this case, however, it is provided according to the invention that at least not both component types, that is to say illuminant units and operating devices, rest flat on the plate-shaped region of the device carrier. Instead, the plate-shaped region has integrally formed spacers which protrude from the plane of the plate-shaped region into at least one of the two mounting regions and form elevated bearing surfaces for the illuminant units or the operating device.

According to the invention, a device support for a lamp is proposed, which is formed by a sheet metal part having a plate-shaped region, are formed by the two mutually opposite mounting areas, wherein a first of the two mounting areas for the arrangement of lighting units, in particular for Arrangement of LED boards is provided and wherein the second mounting area, which is opposite to the first mounting area, is provided for the arrangement of at least one operating device for powering the lamp units. According to the invention, the plate-shaped region has integrally formed spacers which protrude from the plane of the plate-shaped region into one of the two mounting regions and form elevated bearing surfaces for the illuminant units or the operating device.

Characterized in that the illuminant units or the operating device are positioned at a certain distance from the plane of the plate-shaped area with the aid of the spacers according to the invention, the fastening of the components is first facilitated on the equipment carrier. In particular, screwing, for example, the operating device with the equipment carrier now no longer causes that the projecting through the plane of the plate-shaped area screws prevent or affect an arrangement of the lamp units. Instead, lamp units and operating devices can now in fact be arranged directly opposite one another on both sides of the device carrier, without this leading to difficulties with regard to the arrangement of the fastening means. In this way, therefore, the space required for the equipment carrier or the light engine can be reduced. Another decisive advantage, however, is that the illuminant units and the operating device in any case have a certain distance from each other by the inventive design and accordingly reduces the risk of unwanted heat transfer. Even without additional cooling measures so both components can be arranged relatively close to each other, without overheating during operation is to be feared. With the help of the solution according to the invention, therefore, a very compact unit can be created, which includes all responsible for the light generation of a lamp components and can be mounted in a few steps in a luminaire.

As already mentioned, the spacers are integrally formed in the plate-shaped region of the device carrier. This is preferably done by the spacers are formed by embossing. It can be provided in particular that the spacers are curved in two mutually perpendicular directions. This leads to a very stable configuration of the spacers, so that the components arranged thereon, that is to say, for example, the illuminant units, can be stored in a defined manner.

The spacers are preferably formed approximately frusto-conical and may have openings for fastening means in particular in the region of their support surfaces. This may be, for example, simple holes or the like, by which a screwing of the component to be fastened is made possible with the equipment carrier. In order to ensure a surface-defined storage of the component to be fastened, in this case preferably the spacers along a longitudinal direction offset from one another.

[0012] In the device carrier according to the invention, it is thus provided that the illuminant units and the operating device are arranged on opposite sides of the device carrier. To power the illuminant units by the operating device so a corresponding cable connection must be performed from one side of the device carrier to the other. For this purpose, it can be provided according to a preferred embodiment, that the plate-shaped region has at least one recess, through which the guiding of the cable from one side to the other side is made possible. With a suitable positioning of the lamp units relative to the device carrier can be ensured in this case that no damage to the cable sheathing on edges of the sheet metal part is to be feared. In particular, it can be provided that the illuminant unit protrudes slightly into the region of the recess, so that the cable guided around the plate-shaped region does not bear against edges of the device carrier.

Depending on the lamp in which the device carrier according to the invention is to be used, it may be desired that light is emitted not only in the space to which the illuminant units are facing, but also in the opposite area, for example, a so-called indirect lighting to achieve or to lighten the luminaire housing in the form of accent lighting. In this case, it is often provided that additional illuminant units are arranged for this purpose on the side opposite the actual illuminant units side of the device carrier, which cause these additional light output.

According to a preferred embodiment of the invention, however, it can be provided that this secondary light output is also effected by the already existing illuminant units, which is made possible by the fact that the plate-shaped region has openings which a light passage from the first mounting area in which the lighting units are located, allow in the second mounting area. As a rule, at least part of the light generated by the lamp units will be reflected by components or other components of the lamp and fall back onto the equipment carrier. At least a portion of this light may then enter through the openings in the opposite area and then cause the above-mentioned secondary light output. However, in order to be able to use the light emitted by the lighting means as efficiently as possible overall, it is preferably provided that the device support itself consists of a reflective material or has a reflective coating or the like.

A simple attachment of the device carrier according to the invention to a lamp housing is preferably made possible by the fact that this has on two sides of the plate-shaped area extending profiles, which allow mounting in a lamp housing.

According to the invention, a light output unit or light engine is proposed for a luminaire, which has a device carrier according to the type described above, at least one arranged on one side of the plate-shaped area illuminant unit and at least one on the opposite side of the lamp unit operating device.

The invention will be explained in more detail with reference to the accompanying drawings.

Equipment carrier attached primary optics.

As a field of application for the device carrier according to the invention a so-called wet room lamp is described below. However, the concept according to the invention is not limited to such luminaire types as well as to the luminaire shape shown. For example, as an alternative to the elongated embodiment described below, the device carrier could also be made flat.

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

Essential components of the lamp 1 are a so-called light bulb 50, a cover 20 and a later described in more detail, in Figures 1 and 2 not recognizable equipment carrier, which is arranged in the space enclosed by the lamp cover 50 and the cover 20 and space carries the components responsible for the production of light. The luminaire housing is thus formed by the components to be interconnected luminaire trough 50 and cover 20. These enclose an elongated receiving space for the other components of the lamp 1.

It is envisaged that cover 20 and the lamp cover 50 are made of the same material. This represents a first special feature 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 provided that the lamp cover 50 and cover 20 sorted consist of the same material, which may be provided, for example, according to a first preferred embodiment that polycarbonate (PC) is used for both components. This plastic material may be both opaque and opal, then for the trough 50 preferably an opaque material is selected, while on the other hand, the cover 20 is made opal. That is, the cover 20 in this case has at least slightly light-scattering properties, resulting in a homogeneous, uniform light output.

According to another advantageous variant, it can be provided that both the luminaire trough 50 and the cover 20 are formed from polymethylmethacrylate (PMMA). It is a material that can be made crystal clear. This choice of material then leads to the fact that light can escape not only on the cover 20, but also on the also translucent executed tub 50. This can be used to lighten the housing of the lamp 1 in total or via the tub 50 an indirect light output achieve.

However, in both variants, as already mentioned, luminaire trough 50 and cover 20 are made of the same materials, which, inter alia, has 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. As a result, the sealing of the lamp 1 against external influences is further improved.

Another feature of the lamp 1 is that apart from the sealing material described below, the sealing of the lamp interior against external influences exclusively by the two housing components (tray 50 and cover 20) is achieved and both housing components 20, 50 are designed such that they can be connected together without any additional aids. Ideally, the cover 20 and the lamp pan 50 are made entirely 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, since they can be manufactured in a simple manner by injection molding as described below. On the other hand, the elimination of additional connection and sealing measures requires a special interaction of both housing components 20, 50 in the connection area in order to achieve the desired connection and sealing.

In this context, the design of the cover 20 with the measures provided for connection to the lamp pan 50 will be described in detail below first detail. This should be done in particular with reference to FIGS 5 to 9.

Figures 5 and 6 show the first complete lamp cover 20 in a perspective view, on the one hand from the inside (Figure 5) and on the other hand from the outside (Figure 6). The cover 20 in this case has an elongated, dome-shaped shape and is smooth on their outer surfaces. Cleaning the light emitting in the first place responsible responsible surfaces of the lamp 1 is thereby significantly facilitated. The risk of accumulation of dirt particles on the surface of the lamp 1 is reduced.

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

The shape of the cover 20 is chosen such that it is designed approximately trapezoidal both in a section perpendicular to the longitudinal direction and perpendicular thereto. In this case, however, the bottom surface 21 is curved in the areas of the side walls 22 and the end faces 23 via. This shaping 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 bottom surface 21 can in this case be taken as the representations of Figures 3 and 4 can be performed slightly concave, whereby the light output can be additionally influenced in the desired manner.

The responsible for the locking of the cover 20 with the lamp cover 50 and for the dressing of the lamp housing components can be taken in particular from Figures 7 to 9.

Here, it is first seen that the sloping outward side walls 22 and end faces 23 of the cover 20 merge into a circumferential ridge 26 which is aligned approximately perpendicular to the plane of the bottom surface 21 and engage in a sealing channel of the light well 50 described in more detail below should.

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, however, the cover 20 also has a splash guard edge 25 protruding outwardly from the upper edge of the sealing web 26 at right angles to the outside, which can be seen in particular in FIG. This covers in the assembled state of the lamp housing the sealing channel of the lamp pan 50 and thus prevents any force acting directly on the sealing area influence of spray or the like. The risk of a dynamic pressure acting on the seal is thus avoided. This is a supplementary protective measure that does not prevent the fundamental penetration of moisture into the interior of the lamp (this is to be achieved by the interaction of seal and sealing web 26), 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 points at which the latching regions 30, which enable a tool-free locking of the cover 20 with the lamp pan 50, are provided. Several of these latching areas 30 are uniformly distributed over the circumference of the cover 20, wherein a single latching area is shown enlarged in Figures 8 and 9.

In this case, the latching region 30 in particular has a web-like latching projection 31 which is provided on the outer circumference of the sealing web 26 and which is supported on its underside by two trapezoidal support webs 32. This latching projection 31 with the support webs 32 is then intended to engage in a corresponding latching recess of the lamp pan 50. However, in order to enable release of the latching between the cover 20 and the luminaire trough 50 at a later time, a rectangular opening 28 is provided above the latching projection 31 in the splashguard edge 25, via which access to the latching projection 31 is made possible. So here is an interruption of the splash guard edge 25, which allows the subsequent release of the locking between the cover 20 and the lamp cover 50.

At the same time, of course, there is the danger that penetrates through this interruption in the splash guard edge 25 water in the sealing region of the lamp housing. To prevent this, two additional, vertically extending webs 29 are provided, which extend from the end regions of the opening 28 down to the latching projection 31. These webs 29, which have a smaller depth than the latching projection 31, lie 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 pan 50, so that although splash water can penetrate into the region above the latching projection 31, Here, however, then not penetrate further into the connection area, since this area is completely enclosed by the corresponding wall of the housing tray and by the webs 29 and the latching projection 31. The webs 29 and the locking projection 31 accordingly bridge the opening 28 splash guard edge, so that a total of a completely circumferential splash guard in the region of the connection between the cover 20 and trough 50 is achieved.

Furthermore, on the inside of the sealing edge 26 on both sides of the latching regions 30 each have a further web 27 is provided. These additional webs 27 support the interaction of the latching regions 30 of the cover 20 with corresponding latching means of the tub 50, which will be explained in more detail below.

In addition to mention is incidentally that the circumferential splash guard edge 25 in addition to their actual, described above function of protection from spray water also serves as a stacking aid. That is, a plurality of lamp covers 20 of the type shown can be stacked on each other in a simple manner, with a cover 20 then rests with the lower edge of the sealing web 26 on the splash guard edge 25 of the underlying cover 20. This facilitates storage and transport of the cover 20. Furthermore, the shape of the cover is selected such that it can be produced as already mentioned in a simple manner in the context of injection molding.

The design of the lamp pan 50 can be seen in Figures 10 to 17 and 19, wherein the following for the sealing connection of the tub 50 with the cover 20 essential features are to be explained below.

In this case, the luminaire trough 50 initially has a pot-shaped or trough-like configuration and, with respect to its dimensions, essentially corresponds to the dimensions of the cover 20. On the bottom surface 51 and the end faces 53, cable feeds explained later can be realized, via which the electronic feeds Components inside the lamp 1 are connected to external power supply lines.

The two side walls 52 and the end walls 53 of the lamp cover 50 in this case comprise a cover 20 facing the opening, according to the enlarged view of Figure 13, the lamp cover 50 is double-walled in this region of the opening. Strictly speaking, according to the sectional view according to FIG. 14, the side and end walls 52, 53 are initially lengthened by a first web 62. Furthermore, the trough 50 is laterally expanded by a second, angled running web 61, wherein this second outer web 61 then extends substantially parallel to the inner web 62, but this slightly surmounted. In this way, a completely the opening of the tub 50 comprehensive sealing channel 60 is formed, the outer wall is formed by the web 61 and the inner wall by the web 62 and having a seal 63 in its bottom portion. Preferably, this seal is foamed after making the tub 50 in the channel 60 or introduced by alternative methods and then forms a contact surface for the lower edge of the sealing web 26 of the cover 20. This engages over the entire circumference of the channel 60 of time in this and effected by their attachment to the seal 63 that the interior of the lamp housing is protected from dust and / or moisture.

A reliable mounting of the cover 20 on the illuminated tub 50 is achieved by latching portions 65, which are enlarged in the representation of Figure 13 can be seen. These latching regions 65 are formed in that the outer web 61 has a thickening 66, which faces the interior of the sealing channel 60 and a latching recess or

Has locking recess 67. However, this recess 67 penetrates only the thickening 66, but not the entire outer web 61. The housing of the tub 50 is thus closed to the outside in this area.

The positioning of the latching regions 65 corresponds to the arrangement of the previously described latching regions 30 of the cover 20. When assembling the lamp cover 50 with the cover 20 so engage the locking projections 31 in the associated recesses 67 a. The provided on the underside of the locking projections 31 angled support webs 32 in this case form a run-on slope, which cause a lateral emigration of the outer web 61 when placing the cover 20 on the trough 50. As a result, an assembly between the tub 50 and cover 20 is facilitated.

After the cover 20 has been sufficiently introduced into the sealing channel 60 with the sealing web 26, the locking projections 31 and webs 32 fully engage in the corresponding recesses 67 of the lamp pan 50 and the outer web 61 can migrate back to the original position. As a result, a reliable and stable support between cover 20 and tray 50 is ensured, wherein the dimensions of the components responsible for the latching as already mentioned are selected such that the lower edge of the sealing web 26 of the cover 20 in abutment against those provided in the bottom region of the channel 60 Gasket 63 passes and thereby the desired protection of the interior of the lamp housing is achieved.

As can further be seen from FIG. 14, the circumferential splash guard edge 25 of the cover 20 then rests on the end face of the outer web 61 in this assembled state, in order to ensure the splash guard already explained in addition to the internal seal as well as the penetration to avoid larger particles in the area of the seal. Openings only exist through the recesses 28 of the splash guard edge 25 in the region of the individual latches. These openings are required in order to allow a loosening of the latch between the tub 50 and cover 20 at a later time again. However, as already mentioned, the corresponding spaces are then enclosed by the lateral webs 29, which abut against the outer web 61 of the trough 50 from the inside, and by the latching projection 31. In this area entering liquid or dirt particles can not easily get into the sealing channel 60.

This defined interaction between the latching portions 30 of the cover 20 and the latching portions 65 of the tub is further supported by the provided on the inner circumference of the sealing edge 26 webs 27 in the assembled state on the channel 60 side facing the inner web 62 of the tub 50 abut. That is, the components responsible for latching and sealing the cover 20 are defined by the additional support by means of the webs 27 defined in a certain position with respect to the cooperating elements of the tub 50 held.

A release of the latch between the cover 20 and the lamp cover 50 is then characterized in that over the opening 28 of the splash guard edge 25, a tool, such as a flat screwdriver is introduced into the region of the catch. By twisting this tool or screwdriver can then locally the outer web 61 of the trough 50 are bent outwardly, so that the locking projection 31 can leave the recess 67. In this way, so in a very simple and intuitive way the locking between the cover 20 and the lamp cover 50 can be solved again. As already mentioned, this is only possible with the help of an appropriate tool, which is usually available at any time. In this case, prevent the webs 29 and the locking projection 31 also that when inserting the tool accidentally touched the seal 63 and possibly this damaged.

Overall, a reliable sealing connection between the cover 20 and the lamp cover 50 can be achieved in this way so in a simple manner, however, can be solved in case of need again without problems. It is provided - as can be seen in Figure 13 - provided that the locking recess 67 opposite the inner web 62 has an opening or recess 68. Although this is not relevant for the later use of the lamp pan 50 and also for the interaction with the cover 20, it facilitates the production of the tub 50 by injection molding. By the recess 67 corresponding opening 68 namely a demolding of the lamp pan 50 is significantly facilitated after injection molding from the corresponding injection molding tool.

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

With regard to the possibility of supplying external power supply lines 50, several possibilities for forming a feed opening are provided on the lamp pan 50. These are areas 54, 55 and 56, which are initially closed after production of the tub 50, but - in the present case - have annular material weakenings, 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 lamp pan 50 is now that not as usual, the areas are provided for forming feed openings exclusively in the end portions of the lamp cover 50 but beyond a central cable feed is also possible. In the illustrated tub 50, therefore, corresponding areas 54 with material weakenings are initially provided centrally in the bottom surface 51 of the tub 50. In addition, additional portions 55 and 56 are formed in the end portions of the bottom surface 51 and the end surfaces 53. 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, two mutually parallel suspension channels 57 are formed at the end regions of the bottom surface 51. These allow the intervention of, for example, a clamp, which is connected to a suspension cable for suspending the lamp 1. Such brackets are already known and readily allow a cable 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 then to engage, such a measure that a certain clearance for the positioning of the suspension bracket remains. This also increases the flexibility with regard to the arrangement of the lamp 1.

The suspension channels 57 just mentioned can also fulfill a further function beyond this. Since the regions of the housing enclosing the channels 57 form linear surface sections which in particular also project beyond the curved configuration of the further outer side of the luminaire trough 50, these areas can also be used as bearing or storage surfaces, via which in turn a simple stacking is more uniform Lighting trays 50 is possible. As explained in connection with the cover 20 so this leads to a simplified storage and improved transport of the tub 50 to the place of final luminaire mounting.

Further features of the luminaire pan 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 of the trough 50 distributed ribs 70, 80 are positioned. These serve on the one hand to increase the stability of the tub 50, but in particular also 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, two ribs of the first type 70 and four are on one side of the tub 50

Ridges of the second type 80 are provided. The ribs of the first type 70, which are positioned longitudinally at the second and fifth positions in the present case, will be explained below first. 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 can be seen in particular in FIG. 12 as well as in FIG. This first has a first lower portion 71, which - due to the curved outer shape of the trough 50 - has approximately the shape of a quarter ellipse and is provided according to the illustration with a vertical first edge 72 and a horizontal second edge 73. Separated from this first section 71, a further rib section 74 is formed above the horizontal flank 73, which is designed approximately in the form of a right-angled triangle, although the hypotenuse is angled. Together with the upper edge 73 of the first rib portion 71 - and the side wall of the housing - includes the second rib portion 74 a locking recess 75, which serves to hold the device carrier described in more detail below. At its end facing the center of the luminaire trough 50, the horizontal edge 73 also has a slight elevation, by which the latching recess 75 is limited laterally.

In the region of the vertical edge 72, the lower rib section 71 moreover has an approximately triangular further latching recess 76. According to the illustration according to FIG. 15, this enables the latching of a cable holder 90 shown individually in FIG. 16. This holder 90, which is made of plastic for example, is basically configured C-like with a central leg 91 which laterally merges into two inclined side legs 92. which at its outer end in turn parallel to the central leg 91 extending end portion 93 have. In each case an insertion 94 is provided in this end region, so that the end region 93 latched into the recess 76 of the rib 70 engages around the lower region of the rib 70. This cross-like engagement of rib 70 and wire holder 90 causes it to be fixed in the position shown in FIG. Since the wire holder 90 is configured symmetrically and cooperates with the corresponding opposite rib 70 of the tub 50 in the same way, this can be locked in a simple manner in the illustrated arrangement in the lamp cover 50. In this case, feet 95 formed on the underside of the central region 91 support the wire holder 90 on the bottom surface of the trough 50. Accordingly, cables can be laid between this bottom surface and the wire holder 90, which are supported by a plurality of fixed in the tray 50 wire holder so that they extend along the bottom surface of the tub 50 and not affect the further arrangement of additional components in the lamp housing.

In the illustrated configuration, the corresponding recesses 76 are provided for supporting the wire holder 90 in the ribs of the first type 70. 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 90 to be used can hereby optionally be increased, which makes sense depending on the length of the lamp 1.

A release of the locking between the wire holder 90 and the lamp cover 50 can be achieved in a simple manner by being pressed onto the central region 91 of the holder 90 or pulled at this area. Due to the flexibility in this case, the end portions 93 of the wire holder 90 are pulled slightly inward, so that the latching with the corresponding rib 70 is released.

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

The shape of the ribs of the second type 80 can also be seen in FIG. These consist primarily of a lower portion 81, which has a straight vertical edge 82. As already mentioned, 81 recesses or openings corresponding to the recess 76 and the opening 77 of the ribs of the first type 70 could be provided in this lower rib portion.

The upper end of this lower rib portion 81 is provided with a triangular projection 83, which in turn defines - with the side wall of the trough 50 - a latching recess 84. In contrast to the recess 75 of the first rib 70, however, the latching recess 84 is not limited to the top, since here the rib 80 is continued only by a narrow web 85.

Further ribs 88 are further provided on the front end portions of the lamp pan 50. However, these ribs 88 facing the interior (see FIG. 11) extend only over the height of the inner web 62 of the sealing channel 60 and are oriented perpendicular to the ribs of the first and second types 70 and 80 arranged on the longitudinal sides of the tub 50. They support u.a. also a 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, a further particularity of the lamp pan 50 will be briefly described with reference to FIGS. 17 and 18. This has on the outside at least one recognizable in Figure 17 warning symbol 250 with a warning of voltage in the present case flash 251 on. In principle, there are, of course, various possibilities for attaching this warning symbol 250 on the outside after the luminaire trough 50 has been produced. It would be conceivable, for example, a corresponding embossing of this symbol 250 or, of course, a gluing or printing the light bulb 50. In the present case, however, provided that the symbol is created simultaneously during injection molding during the production of the tub.

For this purpose, a special slider used in the injection molding tool is provided, which is shown in FIG. 18 and provided with the reference numeral 300. In this case, use is made of the circumstance that the illustrated triangular-shaped symbol 250 with the flash 251 contained therein can be realized by the use of a tool region with surface regions 301, 302 and 303, which are designed to be staggered relative to one another. The first surface region 301, which forms a first part of the inner region of the triangle, is thus adjoined by the second surface region 302, which has the shape of the flash 251 and is slightly raised in relation to the first region 301. The triangle is finally completed by the surface area 303, which in turn is increased to the second area 302. This special embodiment of the slider 300 has the consequence that in the injection molding process, the symbol 250 - with then corresponding stepwise offset surface areas - can be applied directly to the outside of the lamp cover 50, despite all, however, a subsequent demolding of the tub 50 is possible. In this way, so the goal can be achieved in a very simple and elegant way to produce the lamp tray 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 apparatus support 100, which is initially shown in FIGS. 20 and 21. It is an elongated sheet metal part to which the responsible for the generation of light components of the lamp 1 are to be mounted. A central, plate-shaped region 101 is in this case elongated and dimensioned somewhat shorter than the actual length of the lamp 1. On both sides of the plate-shaped portion 101, the device carrier 100 profiled side legs 102 which are bent in their end portions 103 U-shaped.

The configuration of these profilings or the side legs 102 can be taken from the illustration in FIG. 24, for example. It allows latching with the luminaire pan 50, whereby in this case the latching state shown in FIG.

Order results. It can be seen how the U-shaped bent end regions 103 of the side legs 102 of the device carrier 100 interact with the latching recesses 75 and 84 of the ribs 70 and 80, respectively. In particular, it can be seen that the second upper rib portion 74 of the first type rib 70 forms a limit stop for the end portions 103 in a direction perpendicular to the plane of the opening of the housing pan 50. The projections 83 of the ribs of the second type 80, in turn, form a lateral boundary for the side legs 102. Thus, both rib types 70, 80 fix the side limb 102 primarily in one direction, wherein both directions are substantially perpendicular to one another, so that the device carrier 100 is fixed in the desired position on the housing pan 50 in total. The shaping of the corresponding projections or ribs in this case facilitate the insertion of the U-shaped bent and thus a certain flexibility end portion 103 into the recesses 75, 84 of the ribs 70, 80, so that a simple insertion of the device carrier 100 in the housing tray 50 is made possible , However, this latching can also be released manually, provided that replacement or removal of the device carrier 100 is desired for maintenance purposes.

The device carrier 100 serves to hold both the responsible for generating light bulbs units, in the present case a plurality of LED boards 130 and opposite the positioning of further, responsible for the power supply of the LED boards 130 components. These are corresponding operating devices 140, 141 and connection terminals 142, 143, which are then connected via cables, not shown, to the power supply lines routed in the interior of the lamp or lead from the operating devices 140, 141 to the LED boards 130.

Both the LED boards 130 and the responsible for the power supply components 140 to 143 are thus held by the equipment carrier 100, wherein the components are positioned on both sides of the plate-shaped portion 101. It is provided that on the side of the plate-shaped portion 101, on which the LED boards 130 are arranged, frusto-conical spacers 110 are formed. These spacers 110 form elevated bearing surfaces for the LED boards 130, so that they - as seen for example in Figures 24 and 25 - have a certain distance h to the surface of the plate-shaped portion 101.

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

On the one hand, there is only a very weak direct thermal coupling between the LED boards 130 and the operating devices 140, 141. Both components - ie LED boards 130 and operating devices 140, 141 - generate heat during operation of the luminaire 1, wherein in the case of excessive thermal coupling there would be a risk that the heat would be transferred to the other component and ultimately too high , temperatures not suitable for operation, which 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.

A further advantage is that fastening measures, for example for the LED boards 130 do not lead to impairment in the arrangement of the other components on the opposite side of the device carrier 100. As can be seen in particular from the illustration of FIG. 25, it is provided to screw the LED boards 130 to the device carrier 100. In this case, the spacers 110 each have bores or generally openings 112 at their upper, planar support region 111, which allow the passage of a screw 115. This screw 115 would penetrate without the spacers 110, the plate-shaped portion 101 of the device carrier 100 and protrude on the opposite side. Here then they would possibly hinder the arrangement of the operating devices 140,141 or the like, which now no longer represents a problem due to the use of the spacers 110 according to the invention. In the same way, attaching the terminals 142, 143 with corresponding latching pins which penetrate the plate-shaped area 101 of the device carrier 100 does not lead to impairment of the arrangement of the LED boards 130. The available area of the plate-shaped area 101 can therefore be efficient be used to arrange components for light generation.

The spacers 110 are preferably an integral part of the device carrier 100. This is generally formed by a suitably punched and formed sheet metal part, in which case the spacers 110 are formed by stamping and embossing 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 are stored reliably and stably. A stable mounting of the boards 130 is thereby also supported by the fact that the spacers 110, as can be seen in particular in FIG. 21, are positioned alternately offset from one another in the longitudinal direction of the device carrier 100. A single board 130 should rest on at least three spacers 110, whereby a defined storage is achieved. Of course, the spacers 110 could of course also be provided alternatively or additionally on the opposite side of the device carrier 100 and accordingly allow an arrangement of the operating devices 140, 141 spaced from the plate-shaped region 101.

The fixing of the boards 130 to the equipment carrier 100 is effected, as already mentioned, preferably by means of screwing, the board 130 being supported on at least three spacers 110. 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 e.g. be realized in that the circuit board 130 has a circular hole for screwing in the center, however, elongated holes are provided at the end regions. In the same way, however, the sequence of slot-hole slots can also be provided in the openings 112 in the bearing surfaces 11 of the spacers 110. As a result of this measure, different longitudinal expansions due to the different types of material can be absorbed, wherein, however, due to the central fixation, the circuit board 130 is basically positioned in the desired position with respect to the device carrier 100.

During assembly of the luminaire 1, it is thus provided that first the device carrier 100 is equipped with the components responsible for generating light. This then results in the recognizable in Figures 22 and 23 configuration, with still a wiring between the operating device 140 and the LED board 130 is performed. Since both components are positioned on opposite sides of the device carrier 100, so the connection cable must be guided over a peripheral region of the device carrier 100 from one side to the other side. For this purpose, it is provided that-as can be seen in FIG. 21 -a recess 116 is formed in the end-side end region of the device carrier 100. The operating device 140 with the LED board 130 connecting - not shown in the figures - cable is to be guided by this recess 116, wherein the configuration of the recess of a 116 or the arrangement of the LED board 130 is selected such that the Board 130 with its front end region already in the region of the recess 116 projects. In this way, it is to be avoided that the cable guided from one side to the other side of the device carrier 100 bears directly against the peripheral region of the recess 116 and, if appropriate, damage to the insulation of the cable takes place during the production of the device carrier 100 resulting burrs or sharp edges , Of course, the shape of the recess could also be otherwise chosen to achieve this purpose. In principle, however, it is desired that the cable does not come into contact with sharp edges of the device carrier 100.

As already mentioned, the device carrier 100 is preferably produced as part of a stamping / embossing process, this taking place in one operation. This approach 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 to automate the device carrier 100, e.g. be equipped with the help of a robot, where appropriate provided index openings, which set used for assembly reference positions, can be introduced simultaneously with the other elements during manufacture in the equipment carrier 100.

The appropriately equipped and wired device carrier 100 is then inserted into the housing pan 50 and there snapped or snapped in the manner described above by means of the ribs 70 and 80. The front-side ribs 88 of the trough 50 in this case form a centering or guiding aid, so that a correspondingly suitable positioning of the device carrier 100 in the housing of the luminaire 1 is facilitated.

As already mentioned, it is provided in a special variant for the luminaire housing, that not only the cover 20 but also the housing tray 50 is designed to be translucent in order to achieve a secondary light output here. The light used for this purpose should also come from the LEDs 131 of the LED boards 130, so it is therefore necessary that a light transfer into the housing area is made possible, in which the operating devices 140, 141 are arranged. This is made possible in the case shown by the fact that the plate-shaped region 101 has light passage openings 117 on both longitudinal sides. The in this case oval (other shapes would of course also conceivable) executed and preferably punched out light passage openings 117 are located laterally to those areas in which the LED boards or the operating devices 140, 141 are positioned and should not be covered by these components. Scattered light or light reflected on the inside of the cover 20 can then enter via these light passage openings 117 in the region of the luminaire housing facing away from the cover 20 and be emitted here via the translucent housing tub 50. In order to increase the efficiency of the use of the light generated by the LED boards 130 while the device carrier 100 is preferably carried out reflective. For this purpose, it can either consist of a reflective material or be correspondingly reflective coated or painted.

Finally, the device carrier 110 can also be used to hold a so-called. Primary optics, which should affect the light generated by the LED boards 130 light before the actual light output through the cover 20 of the lamp 1. The use of a corresponding primary optics 150, which is shown in FIGS. 26 to 29, is advantageous in particular when a material which is not highly light-scattering is selected for the cover 20 of the luminaire 1. Without the use of a light-scattering primary optics, the LEDs 131 of the LED boards 130 would then be recognizable as individual point-shaped light sources in this case, which is disadvantageous as a rule because of the desire for uniform or homogeneous light output. The illustrated primary optics is thus provided in particular for the case that the cover 20 consists of PMMA, wherein it could of course also be used in the variant in which the cover 20 is formed of PC.

In such a case, it is then provided to attach the primary optics 150 shown in FIGS. 26 to 29 to the device carrier 100. 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 the primary optics 150 corresponds approximately to that of the lamp cover 20. Also, the primary optics 150 is thus designed elongated and dome-like, so that they can overlap the LED boards 130. At the front end portions of the primary optics 150 locking projections 155 are provided on both sides. These are located on each downwardly projecting webs 156 of the optics 150 and are dimensioned such that they engage from the outside in corresponding latching openings 120 of the device carrier 100. These latching openings 120 are formed in the side legs 102 of the device carrier 100.

The webs 156 of the primary optics 150 thus engage laterally over the plate-shaped region 101 of the device carrier 100, so that the latching projections 155 can engage in the recesses 120 from the outside. Over the wider circumference, the primary optics lie on the surface of the plate-shaped region 101 of the device carrier 100 and in this case engage over both the LED boards 130 and the light passage openings 117. An unwanted light leakage not influenced by the primary optics 150 is prevented in this way. However, if appropriate, the circumferential shape of the primary optics 150 may be selected such that a smaller, e.g. a corner region of the plate-shaped region 101 of the device carrier 100 remains free, that is not covered by the primary optics 150. In this area, for example, a status LED can be positioned, which signals the operating state of the lamp 1. 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 is not scattered by the primary optics 150, which is ensured by the aforementioned measure.

To release the locking between device carrier 100 and primary optics 150 only the webs 156 need to be bent laterally so that the locking projections 155 can leave the recesses 120. A structural unit consisting of equipment carrier 100 and thus latched primary optics 150 is shown in FIG. This assembly can then be used in the whole and thus in a simple manner in the manner described above in the light bulb 50. The primary optics 150 is not located in the region of the U-shaped end regions 103 of the side legs 102, so that the latching of the device carrier 100 with the tub 50 is not impaired.

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 form grooves 158 in the radiating surface of the optical system 150 from the outside, is subdivided into successive segments 159. The light influenced by the primary optics 150 thus consists, before it is emitted by the actual cover 20 of the luminaire 1, of individual partial bundles which correspond to the respective segments 159 of the primary optics 150.

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, however, the segment-like subdivision of the primary optics 150 can also be used to actually emit different light over individual longitudinal sections of the luminaire 1. As a result, for example, there is the possibility not only to illuminate a region assigned to the luminaire 1, ie to lighten it, but also information or instructions could be conveyed in this way. A corresponding control of the LED boards 130 could then be used to generate a time-controlled over the various segments 159 light output, for example, a moving along the light 1 running light is generated, which is a preferred direction (for example, a rescue route or the like ) signals. Also, a light output could be made in different colors across the individual segments 159 away, 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 using the lamp shown. The luminaire is characterized in particular by the fact that the various components can be manufactured in a simple manner and mounted accordingly.
