Definitions

  • 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.
  • 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.
  • 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 very expensive compared to the environment.
  • luminaire trays for damp-proof luminaires are preferably made of plastic and in this case are used in particular Injection molding process produced, since in this way an integrally executed and thus closed lamp tray can be realized.
  • 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 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.
  • a luminaire trough 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.
  • the ribs are arranged on two opposite side walls of the lamp pan.
  • ribs are present, which each have a latching recesses provided for latching to the carrier element.
  • the recesses of the various rib types are designed differently, such that they jointly fix the support member in a predetermined position.
  • 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.
  • 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.
  • 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.
  • ribs 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.
  • 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.
  • 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.
  • 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.
  • a seal is arranged in the bottom area of the sealing channel.
  • 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.
  • 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.
  • luminaire trays In order to supply power to the components inside the luminaire, external power supply cables must be routed inside the luminaire housing.
  • 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.
  • at least one of these areas is formed centrally in a bottom surface of the luminaire trough.
  • such areas are provided on the end surfaces or in the end regions of the bottom surface.
  • corresponding areas for forming feed openings may also be provided at these locations, in addition, however, a corresponding area is now also centrally or centrally located provided, which opens up a greater flexibility in supplying the lamp with power and thus when positioning the lamp.
  • 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.
  • 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.
  • the cover and the tub each consist of the same material.
  • a luminaire according to the invention which has a luminaire housing of the type just described, it can furthermore preferably be provided that means for generating light are arranged in the luminaire housing.
  • 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.
  • FIGS 1 and 2 are first two perspective views of a generally provided with the reference numeral 1 wet room light shown, which is therefore intended in particular for use in areas where, inter alia, 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.
  • the luminaire 1 should then meet the requirements of the protection class IP65, ideally the class IP66.
  • Essential components of the luminaire 1 are a so-called luminaire trough 50, a cover 20 and a later described in more detail in the Figures 1 and 2 unrecognizable equipment carrier, which is arranged in the space enclosed by the lamp cover 50 and the cover 20 space and carries the responsible for the light generation components.
  • 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.
  • the cover 20 and the lamp cover 50 are 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.
  • materials were used for the luminaire tub, which in particular seal the luminaire interior against external influences enabled.
  • the cover was made of a material that met the optical requirements for light output.
  • luminaire trough 50 and cover 20 are sorted from the same material, for example, according to a first preferred embodiment may be provided that polycarbonate (PC) is used for both components.
  • PC polycarbonate
  • 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.
  • 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.
  • PMMA polymethylmethacrylate
  • luminaire trough 50 and cover 20 are made of the same materials, which, inter alia, also 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.
  • 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 are without additional tools can be interconnected.
  • the cover 20 and the lamp cover 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.
  • 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.
  • FIGS. 5 and 6 show first the complete light cover 20 in a perspective view, on the one hand from the inside ( FIG. 5 ) as well as from the outside ( FIG. 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.
  • the cover 20 is provided with light-refracting structures over its substantially entire area, in the illustrated embodiment with ribs 24 extending in the longitudinal direction.
  • 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.
  • other prismatic structures e.g., matrix-like
  • 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 shape leads to an increased mechanical stability of the cover 20, avoids sharp edges on the outside of the cover 20, which adversely affect the light output and in turn facilitates cleaning of the surfaces responsible for the light output.
  • the bottom surface 21 may in this case as the representations of FIGS. 3 and 4 can be removed 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 sealing of the lamp housing components can in particular the FIGS. 7 to 9 be removed.
  • the cover 20 also has a splash guard edge 25 projecting at right angles to the outside from the upper edge of the sealing web 26, which in particular is in FIG FIG. 7 is recognizable.
  • 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.
  • 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 in the FIGS. 8 and 9 is shown enlarged.
  • 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 engages on its Bottom supported 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.
  • 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.
  • a further web 27 is provided on the inside of the sealing edge 26 on both sides of the latching regions 30. 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.
  • 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, 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.

  • the luminaire trough 50 initially has a pot-shaped or trough-like configuration and essentially corresponds in terms of its dimensions to the dimensions of the cover 20. Cable troughs explained later on can be implemented on the bottom surface 51 and the end faces 53, via which the electronic components are located 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, wherein according to the enlarged view of FIG. 13 the lamp pan 50 is double-walled in this region of the opening.
  • the side and end walls 52, 53 initially extended by a first web 62.
  • 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.
  • 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.
  • 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.
  • latching portions 65 which increases in the representation according to FIG. 13 are recognizable.
  • These latching areas 65 are formed in that the outer web 61 has a thickening 66, which faces the interior of the sealing channel 60 and has a latching recess or latching recess 67. However, this recess 67 penetrates only the thickening 66, but not the entire outer Bar 61. The housing of the tub 50 is thus closed in this area to the outside.
  • the positioning of the latching regions 65 corresponds to the arrangement of the previously described latching regions 30 of the cover 20.
  • a loosening of the latching between the cover 20 and the lamp pan 50 then takes place 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 latching. 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.
  • luminaire pan 50 Other special features of the luminaire pan 50 relate to the possibilities for supplying external power supply lines and measures that allow the arrangement of components for light generation within the luminaire housing. These properties will be explained in more detail below.
  • a special feature of the illustrated lamp pan 50 is now that not normally provided as the areas for forming supply openings exclusively in the end portions of the lamp cover 50 but beyond a central cable feed is also possible.
  • corresponding areas 54 with material weakenings are initially provided centrally in the bottom surface 51 of the tub 50.

  • 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.
  • the just mentioned suspension channels 57 can also fulfill an additional function. 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.
  • luminaire pan 50 Other features 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 interior facing ribs 88 (see FIG. 11 ), however, extend only over the height of the inner web 62 of the sealing channel 60 and are oriented perpendicular to the arranged on the longitudinal sides of the trough 50 ribs of the first and second types 70 and 80, respectively. Among other things, they also support a stacking of a plurality of similar lighting trays 50.
  • FIGS. 17 and 18 briefly another special feature of the lamp tray 50 described. This has on the outside at least one in FIG. 17 recognizable warning symbol 250 with a lightning warning in the present case 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.
  • a special slide used in the injection molding tool is provided, which in FIG. 18 is shown and provided with the reference numeral 300.
  • 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.
  • the third essential component of the moisture-proof light 1 is the already mentioned equipment carrier 100, which is initially in the FIGS. 20 and 21 is shown. 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.
  • the device carrier 100 profiled side legs 102 which are bent in their end portions 103 U-shaped.
  • the configuration of these profiles or the side legs 102 can, for example, the representation in FIG. 24 be removed. It allows latching with the lamp cover 50, which in this case then in the locked state, the in FIG. 19 recognizable arrangement 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.
  • 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 ,
  • 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 light source units responsible for the generation of light, 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 connecting terminals 142, 143, which are then connected via cables not shown in detail with the power supply lines led into the lamp interior or lead from the operating devices 140, 141 to the LED boards 130.
  • Both the LED boards 130 and the components 140 to 143 responsible for the power supply are thus held by the equipment carrier 100, the components being positioned on both sides of the plate-shaped area 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 contact surfaces for the LED boards 130, so that these - such as in the FIGS. 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 has several advantages.
  • a further advantage is that fastening measures, for example for the LED boards 130, do not lead to impairments in the arrangement of the further components on the opposite side of the device carrier 100.
  • the spacers 110 in this case each have at their upper, flat support portion 111 holes or generally openings 112, 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.
  • 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 storage of the boards 130 is thereby also supported that the spacers 110 as in particular in FIG. 21 recognizable in the longitudinal direction of the device carrier 100 are alternately offset from each other.
  • a single board 130 should rest on at least three spacers 110, whereby a defined storage is achieved.
  • 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 mounted 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 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 slots can also be provided in the openings 112 in the bearing surfaces 11 of the spacers 110. By this measure, different longitudinal expansions due to the different types of material can be absorbed, however, due to the central fixation, the circuit board 130 is basically positioned in the desired position with respect to the device carrier 100.
  • the device carrier 100 is equipped with the components responsible for generating light. It then results in the FIGS. 22 and 23 recognizable configuration, where 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 it is provided that - as in FIG. 21 recognizable - in the front end portion of the device carrier 100, a recess 116 is formed.
  • 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.
  • 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 .
  • 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.
  • 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 corresponding equipped and wired device carrier 100 is then inserted into the housing tray 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 tub 50 in this case form a centering or guiding aid, so that a corresponding suitable positioning of the device carrier 100 in the housing of the lamp 1 is facilitated.
  • 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 originate from the LEDs 131 of the LED boards 130, so that 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.
  • the device carrier 100 is preferably carried out reflective.
  • it can either consist of a reflective material or be correspondingly reflective coated or painted.
  • 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 in the FIGS. 26 to 29 is shown is particularly advantageous if the cover 20 of the lamp 1, a material is selected, which is not very light scattering. 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.
  • This primary optic 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.
  • the primary optics 150 is thus designed elongated and dome-like, so that they can overlap the LED boards 130.
  • 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.
  • 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.
  • 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.
  • a status LED can be positioned, which signals the operating state of the lamp 1.
  • 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.
  • FIG. 29 An assembly consisting of equipment carrier 100 and thus latched primary optics 150 is in FIG. 29 shown. 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.
  • the primary optics 150 in the illustrated embodiment is that 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.
  • 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.
  • the luminaire is characterized in particular by the fact that the various components can be manufactured in a simple manner and mounted accordingly.
