    Description: [0001] The invention relates to a sealing arrangement, in particular for lamp housings. Such arrangements are known per se.
    Usually seals are inserted between two housing halves and clamped by means of screws such that the seal is firmly pressed between the housing halves. The seal is preferably formed circumferentially. However, these sealing ends have the disadvantage that they must be inserted during assembly in one half of the housing in order then to be able to put on and screw the other half of the housing. So that the seal does not slip when the two housing parts are screwed together, additional precautions must be taken, for example in the form of a positive engagement grip of the seal with one of the housing parts. If, for example, the device or one of the two housing halves is attached to a ceiling or a wall of a room, and if, for example, a person arrives at the interior of the device for maintenance purposes, he must remove the housing half facing him, i. H. unscrew, for example. The problem posed is that the seal may fall off upon removal of this housing part. Only if the seal is fixed in one of the housing halves, for example jammed, can this be prevented. Ie. one of the housing halves must be provided with appropriate Fi¬xierstrukturen to hold the seal in position. This leads to a structurally complex design and relatively expensive production.
    Another disadvantage is that these seals must have a relatively large bearing surface to the respective housing half. This is particularly due to the fact that such seals must be relatively stiff in order to be able to oppose the pressure due to the screwed-together housing halves a corresponding resistance.
    Alternatively, it is also conceivable to effect the sealing effect by pressing small areas mithohem pressure in soft sealing material, which has a highly strained material, Spannn corrosion, embrittlement and cracking over the life result. In order to avoid a deflection of the housing halves, often rigid geometries with inevitably large component height are necessary. Nevertheless, tensions in the material, crack formation at the screw positions as well as a possible component deflection between the screw positions can usually not be avoided.
    The object of the invention is to counter the disadvantages of the prior art.
    This object is solved by the subject matter of the independent claims. Advantageous developments are specified in the subclaims.
    According to the invention, a device having a first housing portion, a second housing portion and a seal is provided. The seal is formed of a flexible and preferably reversible (elastic) material. It is further formed and arranged between the two housing sections, that it is pressed sealingly in a pressed-in, zwi¬schen the two housing sections. The sealing effect or the pressing is achieved by an adhesion effect is achieved between the seal and adjacent housing sections. Because of this, an interior space enclosed by the housing sections and the gasket is sealed at the junctions between the gasket and the respective housing section so that no unwanted substances such as liquids can enter the interior space. This is particularly necessary for appliances that are to be operated in humid environments such as a bathroom. If fluid is present, the electronics commonly provided in such an interior could be damaged. Further, due to the adhesion action in this state, the gasket is prevented from detaching from the adjacent housing portion to a predetermined extent. This has the advantage that any thermal and / or mechanical effects acting on the device do not have immediate or no effect on the tightness. Mechanical effects can arise due to screwing the device on a support body such as a wall or ceiling of a room by due to the tightening the material of one or both housing sections so under mechanical tension that deformed this Mate¬rial. Thermal effects can occur especially in the above-mentioned wet rooms. For example, if the damp room is a bathroom, a person's shower or bath causes a temperature increase in the room which can easily rise above normal room temperatures of, for example, 22 ° C. In contrast, ventilating the room in the winter can lead to a temperature fall, which can also have an unfavorable effect. Such temperature changes typically result in thermal material changes in the housing due to expansion or contraction of its material. The adhesion effect also has the advantage that the sealing surface of the seal relative to the respective housing portion can be minimized.
    The device preferably further comprises a tensioning means. The clamping means is arranged so that it compresses the housing sections in each case in the direction of seal, that the seal between the two housing sections is sealingly pressed. It is thus in the pressed-in state. Ie. the clamping means counteracts any expansion of the seal and ensures the seal to the housing sections.
    The tensioning means is preferably formed by means of elastically formed brackets. These are arranged on the outer circumference of the two housing sections surrounding them umord¬net. The brackets are pressed apart from the two housing sections and the intervening seal and thus tightened; or vice versa: the clamps compress the housing sections and the intermediate seal. Ie. The term tensioning means does not necessarily refer to a single part. This arrangement is particularly easy to manufacture and in particular for flat-construction devices, ie devices with in particular a flat-building first housing portion suitable. Although screws are also possible, but they require due to the necessary screw a certain height dergesamten arrangement.
    The aforesaid adhesion effect is preferably at least partially achieved by the seal being formed and arranged such that a suction effect is created between the seal and at least one of the two housing sections when pressed in. This seems contradictory at first sight as the housing sections and seal are compressed become. However, this configuration makes it possible for mechanical loads occurring in the drive, such as distortion, vibrations and the like, which could force the housing sections apart, to be compensated for at least to a certain extent due to the suction effect of the seal. As a result, the sealing effect is maintained even under these circumstances. The measure is determined by the force achieved by the suction action and the extent to which the seal can relax before it has to lift off one of the housing sections.
    This suction effect is preferably achieved by the seal in a Nichtein¬ pressed state with the at least one housing portion completely encloses a cavity which is at least reduced in the press-in state of the seal. The suction thus arises due to a negative pressure between the seal and adjacent housing portion. The overpressure arises because the elastic material of the gasket tends to deform from the mold in the press-in state towards its shape in the non-press-in state and thus to enlarge the said cavity again.
    The cavity is preferably formed by the seal has on a side facing the at least one housing portion side facing in the direction of the at least one Gehäuseab¬ section concavity. This makes it possible to be able to apply the seal to a respective substantially planar surface. The housing therefore requires no special structures.
    Each of the aforementioned seals can be positively engaged with at least one of the two Gehäuseab¬schnitte. On the one hand, an adhesion effect to one of the housing sections can thereby be effected. On the other hand, this makes it possible to first place the seal on a housing section and to be able to bring it into positive engagement with it, before the other housing section is put on.
    Each seal may be formed of a two-component material. This can be made by injection molding. This allows the use of a dimensionally stable material for any positive engagement and a less dimensionally stable, but more elastic and conforming material for the sealing portion of the gasket, for example around the area of the positive engagement. The seal can therefore be force and / or positively mounted on the respective Gehäuseabschnitt.
    Preferably, the seal is formed circumferentially. As a result, it is possible to apply the seal in a sealing manner on flat surfaces of the housing sections. The housing sections do not require any extra support structures for the seal or structures which sealingly abut the free ends of the seal.
    The seal is preferably cut out of a continuous material. The resulting two free ends of the cut piece are joined together. The joining can take place, for example, by means of fusing, gluing or else by means of positive engagement with one another. This production is particularly inexpensive and yet the gasket can be used as a circumferential seal with the housing sections. In addition, it can be changed in length to different types of housing even during one and the same production cycle and thus adaptable.
    Preferably, the seal is formed of a silicone. In particular, this material can be used very well in the electronics sector owing to its chemical component resistance. An alternative material is silicone compounds which form a type of sticky or strongly adhesive surface and are thus particularly suitable for the sealing according to the invention. Again, alternatively, a hot melt adhesives are suitable which can be used as silicene and in particular can be used for encapsulation of / with illuminants. These substances have a high temperature and media resistance and can be highly transparent. Another suitable material is elastomer with crosslinked or closed-pored surface. As a result, a particularly good seal is achieved. Finally, an adhesion adhesive can also be used, which then bears permanently on one of the housing sections in a permanently sealing manner.
    The gasket may also include a layer of adhesion enhancing liquid. As a result, the actual sealing material may consist of a less adhesion-active material.
    However, this liquid may also have a lower adhesive force than the übri¬ge seal with respect to the respective adjacent housing portion. This makes it possible to provide sealing sections which sealingly abut the housing sections and are sealed to one another via the fluid. This makes it possible to arrange the sealing portions in advance on the housing sections or form. When the housing sections are assembled, the sealing sections are sealingly engaged with each other via the fluid. This allows disassembly of one housing section from the other without damaging or otherwise damaging the seal.
    Preferably, the liquid is an adhesive. This allows the use of two components that would have a greater adhesion force to each other than with the adhesive therebetween. So the housing sections can be easily taken apart here again.
    The aforementioned devices also preferably each have a Druckregulierungs¬ section. This is designed to allow pressure equalization of an interior space enclosed by the gasket and the housing sections to an immediate vicinity of the device. This avoids the case that, for example due to a heat development inside the device, an overpressure can build up in relation to the immediate surroundings of the device and thus be able to push the seal outwards. Otherwise, this could lead to an at least partial loss of the sealing effect of the seal against the housing sections. However, the pressure regulating portion is designed not to let moisture through.
    The seal can be configured as a molded part, molded part, extruded part or coextrusion part. Consequently, many and inexpensive production methods are possible.
    Each of the aforementioned devices may be formed as a lamp. In particular, in these devices, the above-mentioned heat generation may be generated inside the device. In addition, luminaires are often suspended in damp rooms, so that the density in relation to moisture is relevant. Leaks could lead to damage in the Elek¬ronik and / or malfunction, for example due to corrosion in the device.
    The seal can also be provided with light bulbs themselves. Thus, a combined lighting and sealing module is produced, which can be inserted into the housing sections as a whole. It only requires a connection to an external power supply. Or, however, a wireless energy transmission can be provided, for example using a planar coil.
    Advantageously, the lighting means are mounted on at least one circuit board and interconnected. The interconnection is known to be such that the bulbs can be made to glow when an electrical energy is applied. The circuit board allows the positionally accurate fixing and electrical connection of the lamps. The at least one printed circuit board is encapsulated in the seal, combined with the aforementioned advantages with regard to the seal provided with lighting means.
    Preferably, at least one of the at least two housing sections and / or the seal is / are formed from a translucent material. If only the gasket is made of such a material, indirect lighting is possible. If it is translucent together with a housing section, the light can escape in the direction of the housing section and laterally in the region of the seal. If all three parts are translucent, an all-round luminous lamp is produced, as is the case with an incandescent lamp.
    Further features and advantages of the invention will become apparent from the following description of preferred embodiments. 1 shows a luminaire according to an embodiment of the invention, [0029] FIG. 2 shows the luminaire in an exploded view from below in FIG. 1, [0030] FIG. 3 shows a sectional view along a line A - A in FIG. FIG. 4 shows the right-hand section of the luminaire of FIG. 3 with a clamp, [0032] FIG. 5 shows a seal according to a second embodiment of the invention, and [0033] FIG. 6 shows the seal of FIG. 5 in a perspective view.
    The invention will be described by way of example with reference to a lamp 1.
    Figure 1 shows the lamp 1 in a perspective view in the direction of Anbring¬seite on a wall or a ceiling of a room. Ie. the lamp 1 radiates downwards in FIG. The lamp 1 consists essentially of three housing parts 20, 30, 50. The Gehäuseteile 20, 30 include not shown here bulbs 6 a. The housing part 50 essentially contains the operating device for the luminaire 1 and thus provides a Betriebsgehäusedar. The operating housing 50 is sealingly attached to the housing part 30 or formed integrally therewith. The housing part 20 is, as explained in more detail later, preferably designed in the direction housing part 30 open. At the rear end side of the operating housing 50, there is a connection element 2 for connecting a power supply line. an external power supply cable. This can come from a mains voltage connection or from another luminaire 1, so that a through-wiring is created.
    On the opposite end side, the operating housing 50 is closed by means of a cover 51, which is fastened by means of screws 52 to the operating housing 50. The connecting element 2 and the cover 51 are advantageously each attached to the operating housing 50 in a moisture-tight manner. Ie. the parts received in the operating housing 50 are at least protected from outside moisture. Further, a clamp 60 is preferably arranged here by clamping on the upper side of the operating housing 50, which has a screw opening 61 in the center. This opening is used for attaching the bracket 60 beispiels¬weise on a ceiling of a room, a holder or the like. The lamp 1 is ein¬ simply fixed by means of clipping into the bracket 60 and mounted in the room accordingly.
    Figure 2 shows the lamp 1 of Figure 1 in an exploded view of a side opposite to Figure 1 side, d. H. from the side into which the light 1 radiates its light.
    Here it is particularly easy to see that the operating housing 50 and the housing part 30 are formed open to each other in an overlap region. Due to its design, the operating housing 50 is preferably completely open on the side pointing in the direction of the housing part 30. Since the housing part 30 in this area has a larger area than said side of the operating housing 50, the housing part 20 here has a Durchgangsöffnnung 22 which is slightly smaller than the open side of the operating housing 50. This makes it possible, the operating housing 50 sealingly to put the housing part 20 and spielsweise by gluing to fix it.
    In thus open to one side of the interior of the operating housing 50 beispielhaftein is arranged in an operating device that has a holder 8, on which the electronic Bau¬elemente of the operating device for the lamp 1 are arranged or mounted.
    At the rear side facing the front side, the operating housing 50 on the cover 51 with a through hole 53 for a connection element, not shown. This connection element is preferably sealingly attached to the lid 51. At the other end side of the operating housing 50 is the connection element 2.
    The housing part 30 has on a side facing away from the operating housing 50 side a preferably circumferentially formed projection 32 which has a certain distance with respect to a non-be-signed outer edge of the housing part 30. On this projection 32, a seal 10 is preferably placed positively. The seal 10 is made of a material that can exert a certain adhesive force on this housing part 30 when placed on the housing part 30. This allows the gasket 10 to adhere to the housing part 30 and not fall off, for example, in a ceiling construction. The housing part 20 is accordingly placed on the side facing away from the housing part 30 of the seal 10 and fixed to the housing part 30, for example by means of brackets 40 shown here, of which only one is provided with reference numerals. In this case, the seal 10 is slightly compressed so that it rests against the housing part 30 and 20 at least in a moisture-tight manner. The contact pressure must only be so high that the seal 10 seals off an interior space 5 which exists between the housing parts 20, 30 and the seal 10.
    For placing the brackets 40, the housing parts 20, 30 with each other vertically aligned clamping portions 21, 31. These are formed in the example shown so that the brackets 40 are unable to bend the housing parts 20, 30. Furthermore, power transmissions can be realized via the sections 21, 31, if they are made of metal, in order, for example, to ground the luminaire 1. The brackets 40 have a substantially U-shaped cross-section which is enclosed by two mutually parallel projections 41. Ie. the brackets 40 each have a recess 42. In the interior 5, four printed circuit boards 3 are arranged by way of example here, which carry light bulbs 6 which are not visible here, for example in the form of LEDs, and one of which is provided with reference numerals.
    FIG. 3 shows a sectional view of the luminaire 1 along a line A-A in FIG. 1.
    In the middle, an accumulator 7 can be seen schematically in section, which is arranged in the holder 8 of the operating device specified above. Behind the operating device there is the cover 51 with the through-opening 53. As can be seen, the operating housing 50 and the housing part 30 are formed as an example with one another. The bracket 60 has at upper corner portions recesses 63. Furthermore, in the middle of the screw opening 61 can be seen hinted. On the right and left side here in FIG. 3, the clamp 60 has two clamping sections 62 in the form of resilient clip sections. The slightly spaced free ends of these clamping sections 62 clamp the lamp 1 or its operating housing 50 firmly in the clamp 60.
    The printed circuit boards 3, one of which is shown here, are preferably fastened by means of screws 4, 4 on the housing part 30. Each printed circuit board 3 comprises a plurality of lighting means 6, which are formed here in the form of LEDs. Accordingly, the housing part 20 is preferably formed of a transparent material. Thus, the lamp 1 is able to radiate light into the respective space.
    Here right and left side of the circuit board 3 is in cross-section, the seal 10 to recognize, which is formed circumferentially. Furthermore, the protrusion 32 angege¬ above with respect to Figure 2 can be seen, which protrudes from a housing part 20 facing the inside of the housing part 30 in the direction of the housing part 20. On this, the seal 10 is placed formschlüssige engaged.
    Figure 4 shows the right portion of the lamp 1 of Figure 3 enlarged in the neck and provided with a bracket 40. Again, the arrangement of the circuit board 3 with illuminants 6 in the interior 5 including mounting screw 4 can be seen. The screws 4 need not necessarily have a fastening function. They may additionally or alternatively be designed to ground the circuit board 3 or the circuit realized thereon, or to couple it mechanically and / or electrically in an insonstant manner.
    In this view, it is particularly easy to see how the seal 10 is placed with a Ausneh-mung 16 on the projection 32 of the housing part 30. The seal 10 is formed in the example shown in cross-section X-shaped. Ie. the seal 10 has widened foot portions 11, 12 on its side facing the housing part 20 and the housing part 30. These are designed such that they exert a certain adhesive force on the adjacent housing part 20, 30 or their side facing them. In the example shown, this can be done by means of pressing the material against the seal 10.
    The foot sections 11, 12 are preferably formed of a material which is less dimensionally stable than the rest of the seal 10, but which forms an adhesion to the adjacent housing part 20, 30. As a result, the foot sections 11, 12 arrive sealingly in contact with the housing parts 20, 30 when the gasket 10 is inserted, but at the latest when the clips 40 are pushed on. Advantageously, the adhesion causes the housing parts 20, 30 to be incapable of detaching from the gasket 10. This design allows the manufacture of the gasket, for example as a coextrusion part or profile.
    Alternatively or additionally, between the seal 10 and exemplified the Gehäu¬seteil 20 a suction effect can be achieved, as will be described below with reference to Figure 5. Due to the cross-sectional shape of the seal 10, this has a respective recess 14, 15 in the direction of the interior 5 and in the direction away from the interior 5. The bracket 40 has, due to its groove-shaped formation on an inner space 42 which serves the receiver of the assembled housing parts 20, 30 with intermediate seal 10. The projections 41 have on their sides facing each other in the region of their free end surfaces 44, which face away from each other in the direction of the free end and thus form a Anlauf¬ bevel for the assembled housing parts 20,30. If the clip 40 is pushed from the left onto the housing 20, 30, the protrusions 41 are forced apart due to the chamfers 44, so that the clip 40 with its spring-formed protrusions 41, 41 compresses the housing parts 20, 30 and thus against the inside ¬ ordered seal 10 urges. As a result, the seal 10 is arranged sealingly against the inner sides of the housing parts 20, 30 facing it.
    The projections 41 have in the region of their free ends a respective section 43. The sections 43 have a smaller distance to each other than the other areas of the projections 41 to each other. This makes it possible for the clip 40 to rest against the housing parts 20, 30 in clamping or clamping manner only in the region of the sections 43, 43. The abutment area is preferably such that the protrusions 43, 43 press centrally against the seal 10. As a result, the pressure of the clamp 40 is introduced via the sections 43, 43 and the housing halves 20, 30 substantially perpendicularly and advantageously along one and the same line of force into the seal 10 or its center. As a result, there is no force on the seal 10 which could force the seal 10 to the right or to the left. Ie. the seal 10 is securely held in position.
    FIG. 5 shows a seal 10 according to a second embodiment of the invention.
    The seal 10 differs from the first embodiment of the invention substantially in that here the recess 16 is missing. Furthermore, the seal 10 beispiels¬haft in the region of the foot portion 11 on a concavity. As a result, the seal 10 forms an upper side of a preferably circumferential recess 13. Due to the circumferential design of the seal 10, the latter, with the housing part 20 placed thereon, not shown here, initially encloses a cavity. When the clip 40 is pushed onto the housing parts 20, 30 as described above, the housing part 20 is urged toward the housing part 30, and the cavity between the seal 10 and the housing part 20 is preferably completely closed. Ie. the air between the seal 10 and the housing part 20 is completely displaced. Due to the flexible design of the seal 10, there is thus a depression between the housing part 20 and the seal 10, which ensures that the housing part 20 is retained on the seal 10 to a predetermined extent. This predetermined measure corresponds to the holding force resulting from the depression between the seal 10 and housing part 20.
    Thus, as described above, if the luminaire 1 is mounted on the ceiling side, and if the brackets 40 are removed for maintenance, the housing part 20 can not readily fall off. As a result, the operating safety is increased, and the person can not be injured by a falling cover.
    The above-mentioned brackets 40 cause that also here the seal 10 is securely held in position.
    FIG. 6 shows the seal 10 of FIG. 5 in a perspective view. The recess 13 is exemplarily formed on the here upwardly facing side of the seal 10. Furthermore, the foot sections 11, 12 can be seen by way of indication, as well as the recesses 15, 16 formed therebetween.
    The invention is not limited to the embodiments described above.
    For example, the seal 10 shown in Figure 5 may also have a corresponding recess 13 on its underside. Further, the recesses 16 may be formed on both sides of the gasket 10. In addition, the recess 16 and the projection 32 corresponding therewith can assume any cross-sectional shape which serves to bring the seal 10 into contact with the respective housing part. For example, provision may be made for the projection 32 to have a mushroom-shaped cross-sectional shape, with the result that the seal 10 engages behind it with a preferably complementary recess 16 and is therefore retained on the housing part 30, for example. The recess 16 is designed so that the seal 10 due to its material safely acquires an adhesive effect with the housing part 30.
    The seal 10 has, at least on the sealing surfaces facing the housing parts 20, 30, an elastic sealant which can connect to the adjoining housing part by means of lesser forces than the force generated by the clamps 40. The sealant thus forms an at least water-impermeable bond with the housing part by means of adhesion.
    Preferably, the sealing effect is carried out immediately upon application of the seal 10 to the housing part 20, 30. For this purpose, the seal 10 may be formed of a modified material having only a touch and a low contact pressure on the housing part 20, 30, for example, only due to the weight of the seal 10 requires. For this purpose, silicone compounds are suitable which form a "sticky" or strongly adhesive surface, so that the sealing effect occurs very quickly. Furthermore, silicone is very suitable for the electronics sector because it is chemically resistant.
    If the seal 10 is also given a suitable shape as described above, for example by forming an elastic, concave shape according to the principle of a suction cup with an elongated extent, it is possible to increase the number and bearing width of closure elements such as the aforementioned clamps 40 to reduce. Furthermore, the contact surface of the seal 10 on the housing part 20, 30 can be reduced. Due to the suction effect, the seal 10 generates the necessary holding forces themselves. It only needs to be prevented from relaxing again, for which purpose the aforementioned clamps 40 are mentioned by way of example. Instead of the brackets 40 but also, for example, a screw zwi¬schen two housing parts 20, 30 is conceivable that sets the seal 10 under tension.
    In order to prevent heat evolved in operation in the interior space 5 from acting outwardly of the seal 10 with respect to the housing 20, 30 and possibly reducing the sealing effect, it is preferably provided that at a location of the housing 20, 30 or the operating housing 50 an air-permeable membrane is ausgebil¬det, which ensures that in the interior 5 no pressure can occur. Alternatively, a shape is possible with which the seal 10 comes to lie in the direction of the housing exterior on a respective side of the housing part 20, 30. This would mean that the overpressure presses the seal 10 against this very side of the respective housing 20, 30 and can not press out of it. The seal 10 remains in position, and the sealing effect is maintained upright.
    The moisture-proof arrangement of the seal 10 on the housing parts 20, 30 makes it possible to use such a device or luminaire 1 in humid rooms, for example in bathrooms.
    The seal 10 may be made of various materials. For example, it can be provided that the seal 10 is formed in the center, that is to say in a region which does not bear against one of the housing parts 20, 30, from a relatively dimensionally stable material. At its housing parts 20, 30 facing portions, the seal 10 is formed from a suitable for the Dich¬tungswirkung, causing the aforementioned adhesion material. This makes it possible to form the seal 10 as a molded, injection-molded, extruded, or co-extruded part.
    Although the seal 10 has been shown to be circumferential, it is clear that it can not be formed circumferentially. It can, for example, be supported with its two free ends on one of the housing parts 20, 30, or be pushed into the respective housing part 20, 30 via a Fe-der-Nut connection, for example. Such a tongue-and-groove connection can be realized, for example, by means of a dovetail guide. It must therefore abut with its free ends on the face side on one of the housing parts 20, 30 only in each case in a sealing manner. This could be useful in devices in which a cover must be abgedich¬ as a housing part with respect to another housing part with a corresponding opening. For this purpose, the seal 10 may be sealingly attached outside the hinging of the lid to the other housing part on the cover or other housing part. When the cover is closed, its edges to be sealed and the edges of the other housing part to be sealed come into sealing engagement with the seal 10.
    Or a part of the seal 10 is disposed on a housing portion, and the other part on the other housing portion. When joining both Gehäuseab¬schnitte the two parts of the seal 10 come at their free ends together sealingly conditioning, either by force and / or interlocking mesh.
    Both types of seals 10 (circumferential and non-circumferential) can be formed by producing an endless profile, for example by means of coextrusion, which is then cut to length in accordance with the desired length of the seal 10. After cutting to length, the gasket 10, when it is to be circumferentially formed, is connected together at its thus two free ends.
    Further, it may be provided that at the portions of the sealing system with the housing part 20, 30, a liquid with adhesion-enhancing effect is applied. This allows the housing parts 20, 30 to be able to disassemble without losing the seal arrangement, or the seal 10th to have to exchange. This can alternatively or additionally be achieved by the seal 10 with two housing parts 20,30 positively engages. This can be achieved by simply placing the housing parts 20, 30 on top of each other. For this purpose, both housing parts 20, 30 on the mutually facing sides or surfaces projections, for example, have circular cross-section, and the seal 10 has on corresponding, opposite portions concave, preferably complementary to the projections formed recesses auf.Sind the side of these recesses nor the foot sections 11, 12, it may be ensured that the gasket 10 securely seals, although possibly the free-standing protrusions forming the recess are forced apart by the corresponding protrusions on the housing sides 20, 30.
    Furthermore, instead of the recess 16, the seal 10 can also have a projection, which is inserted in a sealing manner in a corresponding recess on or in the respective housing part 20, 30. The seal 10 may preferably be formed of a material having a Shore hardness according to the dimension A30 or A10. It can be formed from any elastomer which has a cross-linked, ie closed-cell surface and thus comes into secure sealing with the respective housing part 20, 30. If the seal 10 is formed, for example, from silicone, this can be formed transparently. This makes it possible to integrate lighting means 6 in the seal 10, d. H. preferably with the seal 10 to encase. This can of course also be done with other Bauelemen¬ten or with the entire circuit boards 3 or other electronic components or circuits. As a result, finally, a complete lighting and sealing module can be formed, which simply has a maximum of two Anschlüs¬se outward for contacting with the operating device and otherwise only be placed as a whole between the housing parts 20, 30, and the lamp 1 is complete as soon as the housing parts 20, 30 are fixed to each other.
    The adhesion effect between the seal 10 and the adjacent housing section 20, 30 provided in the context of the invention can be designed so strongly that, for example, the housing section 20 is held in the ceiling-mounted luminaire 1 solely by the seal 10. In order to avoid that for unforeseeable reasons, despite everything during the Be¬triebs the housing portion 20, which may be formed, for example, as a disc drops down (which could be caused for example by the heat occurring during operation in the interior 5hervor), are additional Fortifications for example in the form of the aforementioned brackets 40 providable. The brackets 40 are primarily a safety measure in this case, but they do not play a decisive role in particular for the sealing effect between the seal 10 and the housing sections 20, 30. Thus, preferably, the clamps 40 serve to ensure the permanent sealing effect between the seal 10 and housing sections 20, 30.
    The aforementioned recess 13 serves, as described, to form a cavity here to the housing portion 20. It is clear that this recess 13 can take any other form, provided that the cavity to the adjacent housing portion 20, 30 at the
    Pressing the seal 10 in its press-in state on ebendiesen housing portion 20, 30zum at least reduced, if not eliminated. The adjacent housing portion 20, 30 need not have a flat bearing surface for the seal 10 with respect to the cavity. It should only be shaped so that, when the gasket 10 is not pressed, this area completely encloses a cavity. For example, this surface could have a convexity in the direction of seal 10, the curvature of which, however, is less than the curvature of the aforementioned concavity 13.
    Also, the surface of this housing section 20, 30 could, for example, have a Konkavi¬tät and the seal 10 may be flat on the opposite edge. The cavity therebetween is also at least compressed when the gasket 10 and the corresponding housing section 20, 30 are compressed, thus again producing the aforementioned suction effect.
    Although the invention has been described in conjunction with a luminaire, it is to be understood that the invention is applicable to any apparatus which requires sealing its interior to the exterior.
    It is essential that the seal 10 has due to an adhesion effect with the respective adjacent housing part 20, 30 as a housing portion and thereby adheres to this housing part 20, 30 with relatively small forces and allows a seal, either by means of suitable material selection and / or correspondingly formed contours / structures.
    As a result, the invention provides an enormously simple solution to realize housing of at least moisture-sealed exterior, in particular electronic devices to realize, and with simple and inexpensive means. Moreover, such seals can be made very small, so that at least material is saved.
