    description
    LAMP
    The present invention relates generally to the field of lights with sealing function.
    Examples of such lights are wet room lights, which provide a corresponding degree of protection (for example, at least IP67). Such luminaires generally have, on the one hand, a luminaire housing and, on the other hand, a cover provided on the light emission side or light exit side, which is translucent and, in particular, serves for the light emission of the luminaire. The lamp itself and preferably also the electronics of the lamp are surrounded by the lamp housing and the cover and preferably sealed according to the outside.
    To provide a correspondingly high degree of protection (eg. To avoid the ingress of water) are provided in such lights usually seals between the two aforementioned components. These seals require a relatively high contact pressure in order to achieve the desired tightness. This in turn requires a high stability of the lamp housing, the cover and the closures for connecting these two components. As a seal, for example, a classic seal, such as a ring cord seal used. This is provided between these two components such that the interior of the lamp is sealed to the outside. In this case, a corresponding seal can be provided or inserted laterally circumferentially. For this purpose, a groove is provided in which the seal is provided.
    An alternative embodiment is the introduction of a sealing foam, which is introduced in accordance between the two components to seal the interior to the outside. However, such foams absorb moisture to some extent, which has a detrimental effect on the sealing function and also on the durability of the seal, so that the requirements of a certain degree of protection may no longer be maintained.
    Also lights are known, which have a sealing lip between the lamp housing on the one hand and the cover on the other hand. Such a configuration usually requires additional mechanical support elements for holding the cover to the lamp housing.
    It is therefore an object of the present invention to provide a luminaire of the type mentioned, which ensures a secure seal of the lamp interior with a simple and secure connection of the luminaire components.
    This object is solved by the subject matter of the independent claim. The dependent claims further form the central idea of the invention in a particularly advantageous manner.
    The present invention relates to a luminaire, comprising a luminaire housing with a laterally closed edge, through which a light exit area is defined, and a translucent (eg. Transparent) cover, which is arranged in the light exit area. Furthermore, a circumferentially closed seal with a first and a second circumferentially closed sealing lip is provided. The first sealing lip extends between the edge and the cover and cooperates with a locking profile for sealing and holding the cover to the lamp housing. The second sealing lip extends between the lamp housing and the cover so as to bias the first sealing lip in sealing engagement with the locking profile. The sealing lips may be provided separately to form the seal or formed integrally with each other.
    By means of the lamp according to the invention, it is possible by the seal with two sealing lips both the function of sealing the lamp as well as the holder of the lamp components together - so in particular the cover in the lamp housing to accomplish in a simple manner. Different functions are provided by means of the sealing lips. To serve both sealing lips functionally according to the sealing of the lamp components to each other. While the first sealing lip also serves to hold the cover to the luminaire housing (= closure function), the second sealing lip, by means of appropriate design and arrangement, provides secure reception of the first sealing lip in the latching position while at the same time providing a relatively high contact pressure to achieve a desired tightness , In this way, a desired sealing function and support function can be achieved safely; without the use of additional and possibly separate support elements.
    According to a further aspect, the first sealing lip is preferably fixed with a fixed end to the cover or to the lamp housing. In the same way, the second sealing lip can be fixed with a fixed end to the cover or to the lamp housing. The respective free end of the sealing lip is then preferably in sealing contact with the respective other of the cover and the lamp housing in order to fulfill the functions described above. In their design as a sealing lip, these have a spring function when tightly formed by the correspondingly forced deformation in order to exert a biasing force against their deformation.
    The second sealing lip may extend transversely between the cover and the edge such that its fixed end is closer to the light exit region than its free end. In this way, in addition to a good sealing function in particular a bias to the first sealing lip can be achieved safely.
    In a preferred embodiment, the lamp further comprises a side facing away from the light exit region end of the edge extending away and the light exit area facing, circumferentially closed transverse wall of the lamp housing. The second sealing lip extends between the transverse wall and the cover to cooperate preferably with the transverse wall or the cover for sealing and biasing the first sealing lip. By providing the aforementioned transverse wall, a rear support of the second sealing lip can be provided, so that in a simple manner, a bias in the direction of the first sealing lip can be carried out to bias the first sealing lip in a secure manner to secure the cover. Since the transverse wall also extends transversely to the edge, a secure sealing engagement of the second sealing lip is made possible. The resulting by manufacturing tolerances and different thermal expansion of the lighting components three-dimensional relative movements are thus particularly effectively absorbed by the seal, so that the seal prestressing constant and thus the seal always remains reliably tight throughout the service life.
    The second sealing lip preferably extends transversely between the cover and the transverse wall such that its free end is closer to the edge than its fixed end. In this way, a reliable sealing function can be provided with appropriate biasing function.
    The first sealing lip may extend transversely between the cover and the edge such that its free end is closer to the light exit region than its fixed end. In this way, a corresponding holding function of the first sealing lip can be provided in cooperation with the corresponding latching profile. In addition, the sealing function is improved, since the first sealing lip is pressed in pressure from the outside more in the sealing and holding position.
    According to a preferred embodiment, the second sealing lip extends between the lamp housing, preferably the edge or the transverse wall, and the cover to cooperate preferably with a further latching profile for sealing and biasing the first sealing lip. In this way, the second sealing lip can be provided in addition to the first sealing lip in a sealing manner. In addition, by providing a further latching profile, a secure support of the second sealing lip can be provided in order to achieve a secure pretensioning of the first sealing lip in addition to the sealing function.
    Both the locking profile of the first sealing lip and the further locking profile of the second sealing lip may be part of the lamp housing or part of the cover and are particularly preferably formed integrally therewith. The locking profiles can be formed circumferentially closed. It is also conceivable that the locking profiles are designed in several parts and are then preferably distributed over the circumference of the lamp or the lamp housing (evenly).
    The cover may have a circumferentially closed and preferably annular web, which preferably extends with a defined distance D along the cover edge. The first sealing lip may be arranged on the web or abut gene on the web. Likewise, the second sealing lip can be arranged on the web or abut gene on the web. The web may protrude toward the transverse wall with respect to the remaining cover; So therefore protrude from the rest of the cover in one direction, which points to an inner region of the lamp housing. By providing the aforementioned web, a secure and preferably "invisible" attachment or contact of the seal or its sealing lips can be provided in order to reliably provide the multiple function of the seal.
    The cover can on the side facing away from the inner region of the lamp housing sides - ie on its outer side - and in particular on the opposite side of the web and at least in a region opposite the web have a structuring, which preferably extends to the nearest cover edge. In this way, the cover may be formed such that the intended bridge from the outside not or only a small extent (as such) can be seen to allow a substantially harmonious and uniform light output of the lamp on the cover and a uniform appearance of the light of to provide outside.
    The locking profile and, if present, that further latching profile can on one of the cover (in particular the radially end-side cover edge or the web) facing side of the edge or on a side facing the edge of the cover (in particular the radially end-side cover edge or the web ) be provided. The latching profile or the further latching profile can be designed as in the space between the edge on the one hand and cover (in particular the radially end-side cover edge or the web) on the other hand protruding projection. The preferred integral design of the locking profile with the cover or the lamp housing ensures that preferably no visible closure elements on the luminaire surface are visible outside, so that the aesthetic appearance of the lamp is improved. Thus, in addition costs for additional closure elements can be omitted.
    In a preferred embodiment, the sealing lips are directed away from each other (their main directions of extension are therefore not parallel and include an angle) and preferably spread apart from each other. By this oppositely directed extension of the sealing lips away from each other in particular the bias and thus the holding function of the seal can be securely provided, while at the same time by a corresponding provision of relatively high contact pressures, the sealing function is guaranteed to be sure.
    In a preferred embodiment, the first sealing lip in cross-section (ie in particular with respect. Their cross-sectional area) is formed stronger than the second sealing lip. The first sealing lip may have a higher spring constant than the second sealing lip. In this way it is possible, the sealing lip for holding function - ie the first sealing lip - form correspondingly stronger, in addition to the sealing function also safely accomplish the holding function. The second sealing lip, however, can be provided with less material and thus more cost-effective to provide their intended functions (seal and bias of the first sealing lip) material saving but safe.
    In a preferred embodiment, the seal - for example by means of a two-component injection technology - with the cover (eg. The web) or the lamp housing connected. Alternatively, the seal or at least one of the sealing lips may also be formed integrally with the cover or the luminaire housing. The seal can thus be provided safely and inexpensively in any way. In particular, when forming the seal by means of a two-component injection technology, the seal may be made of polyurethane (PUR). The cover itself is preferably made of a correspondingly known material, which is mechanically stable enough and also translucent. The material may, if desired, have light-influencing particles; For example, light-scattering and / or light-converting particles.
    The lamp housing, and preferably the transverse wall may have a circumferential guide web for the cover, which is located radially inwardly with respect to the seal and preferably extends to the light exit area or to the light exit surface. In this way, the cover with the inwardly projecting seal or the sealing lips can be defined defined to safely fulfill their functions.
    In one embodiment, between the cover, in particular the front-side cover edge, and the lamp housing, in particular the edge, a circumferential gap may be formed. However, it is also conceivable that the cover circumferentially and preferably rests flat on the edge, preferably pressed by means of the first sealing lip on the edge in abutment. In this way, an aesthetically harmonious luminaire with the least possible or no gap can be provided. By means of the sealing lips, the cover thus inserted is preferably centered in the luminaire housing. In particular, in the embodiment with circumferential gap so a uniform gap can be formed around it. The provision of the sealing lips also ensures a harmonious image even when looking into the gap, as essentially no support elements or the interior of the lamp can be seen. For this purpose, the seal can be provided from a corresponding material or in a corresponding color, so that it is visually not visible from the outside (disturbing) and also causes no shading effects.
    The cover, except for a possibly provided web, is preferably formed flat. Thus, a harmonious and aesthetic image of a lamp is produced for example for recessed lighting.
    Further aspects and advantages of the present invention will be described below with reference to the embodiments of the figures of the accompanying drawings.
    Figure 1 shows a side cross-sectional view of a lamp according to the invention according to a first embodiment, and Figure 2 shows a detail of a lamp according to the invention according to a second embodiment.
    Figures 1 and 2 show two embodiments of a lamp according to the invention 1. These are described below together and pointed out the differences. The luminaire 1 according to the invention has a luminaire housing 2. The luminaire housing 2 in turn has a laterally closed edge 3, by which a light exit area L is fixed. The luminaire housing 2 may be made of metal, for example a sheet metal, of plastic or other materials.
    Furthermore, the luminaire 1 has a translucent (eg transparent) cover 4, which is arranged in the light exit region L. The cover 4 may also be made of a plastic material or glass. Preferably, the cover is provided as an injection molded part.
    The lamp 1 also has a circumferentially closed seal 5. The seal 5 is preferably made of a soft component such as polyurethane (PUR) provided. The seal 5 can be made, for example, by means of a two-component injection molding process together with the cover 4. However, it is also conceivable that the seal 5 is produced on the side of the luminaire housing 2 and preferably together with it in a two-component injection molding process.
    The seal 5 has a first circumferentially closed sealing lip 51 and a second circumferentially closed sealing lip 52. Generally, the first sealing lip 51 extends between the edge 3 and the cover 4 and acts together with a locking profile 6 for sealing and holding the cover 4 to the lamp housing 2 together. In this case, the first sealing lip 51 with a fixed end 510 on the cover 4 (see Figures 1 and 2) or on the lamp housing 2 (not shown) may be arranged fixed. The respective free end 511 is then in sealing contact with the other of the cover 4 and the lamp housing 2. The locking profile 6 is provided on the side of the free end 511 on the corresponding component of cover 4 or - as shown - Luminaire housing 2 and preferably with this Component 2, 4 integrally formed. In the figures, the free end 511 here in its rest position (not biased state) is shown, wherein the first sealing lip 51 would of course be biased accordingly in operative connection and thus holds the cover 4 securely in the lamp housing 2. The bias not only causes the holding function, but also provides the sealing function.
    As shown in the figures, the first sealing lip 51 preferably extends transversely between cover 4 and edge 3, that their free end 511 is closer to the light exit region L than its fixed end 510. In this way, quasi the first sealing lip abuts 51 in the locking profile 6 in order to keep the cover 4 securely in the lamp housing 2. In addition, a secure sealing function is provided in this way, since the seal is pressed under load from the outside further in their sealing contact.
    In its most general form, the second sealing lip 52 extends between the lamp housing 2 and the cover 4 so as to bias the first sealing lip 51 in close contact with the locking profile 6. The second sealing lip 52 is thus provided such that it presses the first sealing lip in the latching position and thus improves the mounting of the cover 4 in the lamp housing 2 and at the same time by a correspondingly relatively high contact pressure, the sealing function of the seal 5 improves overall.
    Comparable to the first sealing lip 51 and the second sealing lip 52 may be fixed with a fixed end 520 on the cover 4 or a lamp housing 2, wherein the respective free end 521 in sealing engagement with the other of the cover 4 and the lamp housing. 2 stands. To illustrate the bias of the second sealing lip 52 and this - as the first sealing lip 51 - is shown in the non-biased state in the figures.
    In a preferred embodiment, which is not shown in the figures, the second sealing lip 52 extends between the lamp housing 2 (for example, the edge 3) and the cover 4, preferably with a further locking profile (not shown) for sealing on the one hand and bias of the first sealing lip 51 on the other hand cooperate. The second sealing lip 52 extends in such a way transversely between the cover 4 and the lamp housing 2 (for example, the edge 3) that its fixed end 520 is closer to the light exit region L as its free end 521. In this way, in particular the biasing effect of second sealing lip 52 are provided toward the first sealing lip 51 in the direction of action, in order to increase the holding and sealing function of the first sealing lip 51 and at the same time to achieve a high sealing effect of the second sealing lip 52 itself.
    In the embodiments shown in Figures 1 and 2, the lamp 1 further comprises a side facing away from the light exit region L end of the edge 3 and the light exit area L facing, circumferentially closed transverse wall 7 of the lamp housing 2. The second sealing lip 52 extends between the transverse wall 7 and the cover 4, preferably to cooperate with the transverse wall 7 and the cover 4 for sealing and biasing the first sealing lip 51. The second sealing lip 52 may extend transversely between cover 4 and transverse wall 7 such that its free end 521 is closer to the edge 3 than its fixed end 520. In this way, in addition to the function for biasing the first sealing lip 51, a particularly good Be provided sealing function, as in any penetrating moisture and in particular liquid or pressure on the second sealing lip 52 from the outside, this pressed into stronger sealing system and thus the sealing function is further improved.
    As shown in the figures, the cover 4 may have a circumferentially closed and preferably annular web 40. This web 40 may preferably extend with a defined distance D along the cover edge 41. By this offset D of the web 40 of the cover edge 41 of the web 40 is slightly recessed radially and thus not visible or difficult to see from the outside, so that the aesthetic appearance of the lamp 1 is improved overall. This is particularly advantageous in the case of a luminaire 1 according to the exemplary embodiment of FIG. 1, in which a peripheral gap S is formed between the cover 4, in particular the frontal cover edge 41, and the luminaire housing 2, in particular the edge 3. As a result of the rearward displacement of the web 40, it is thus not or only with difficulty visible from the outside through the gap S. By the seal 5, the cover 4 is preferably further centered with respect to the lamp housing 2; ie in particular transversely / radially in the light exit region L spanning plane.
    In an embodiment according to the figure 2, the cover 4 can also circumferentially and preferably rest flat on the edge 3 and is preferably pressed by means of the first sealing lip 51 on the edge 3 in Appendix. By dislocating the web 40, a protruding edge region 42 of the cover 4 can thus be provided, which protrudes beyond the edge 3, in order thus to harmoniously shape the appearance of the luminaire 1 from the outside.
    The cover 4, except for a possibly provided web 40, is preferably formed flat to form a total of the appearance of the lamp 1 aesthetically harmonious.
    The web 40 is preferably with respect to the rest of the cover 4 to the transverse wall 7 towards or is in a direction from the rest of the cover 4, which faces an inner region I of the lamp housing 2.
    In a preferred embodiment, the cover 4 on the inner region I of the lamp housing 2 side facing away 43, in particular on the web 40 opposite side 43 and at least in the web 40 opposite region structuring, which is preferably up extends to the nearest cover edge 41. Thus, the appearance of the lamp can be formed as harmonious as possible from the outside in Providence of a corresponding bridge.
    The locking profile 6 and, if present, the further locking profile can on one of the cover 4 and in particular the radially end-side cover edge 41 or the web 40 facing side of the edge 3 or on a side facing the edge 3 of the cover 4, in particular the radially end-side cover edge 41 or the web 40 may be provided. In this case, the latching profiles 6 are preferably formed integrally with the cover 4 or the luminaire housing 2 or its edge 3. Thus, a corresponding locking profile 6 can be provided for mounting in a simple manner and integrally with the corresponding component 2, 4. Likewise, an external appearance of the lamp 1 can thus be designed as harmonious as possible, since no latching profiles 6 are present or recognizable from the outside.
    The locking profile 6 and, if present, the further locking profile can be formed as in the space R between the edge 3 on the one hand and cover 4 (in particular the radially end-side cover edge 41 or the web 40) on the other hand protruding projection 8. Thus, a comparatively simple trained locking profile 6 can be provided in a simple manner, in which the first sealing lip 51 can snap in a simple manner when inserting the cover 4 in the lamp housing 2.
    In a preferred embodiment shown in the figures, the sealing lips 51, 52 are directed away from each other and preferably spread apart from each other. In this way, the above-described functions can be reliably provided, in which the sealing lips 51, 52 in opposite directions - ie towards each other - biasing and thus each produce a relatively high contact pressure. In this case, the second sealing lip 52 presses the first sealing lip 51 securely in its locking position and vice versa holds the first sealing lip 51, the second sealing lip 52 as well in safe investment to accomplish a total of a high sealing function at safe locking receptacle.
    In a preferred embodiment, as can also be seen from the figures, the first sealing lip 51 may have a greater cross section than the second sealing lip 52. The first sealing lip 51 may have a higher spring constant than the second sealing lip 52. Thus, the respective functions of the sealing lips 51, 52 can be met with the least possible use of materials. The first sealing lip 51 can safely fulfill the holding function with stronger training, while the second sealing lip 52 can meet the corresponding bias by smaller configuration, while both fulfill their sealing function safely.
    The seal 5 may, as already mentioned, be connected by means of a two-component injection technology with the cover or the web 40 or with the lamp housing 2. However, it is also conceivable that the seal 5 is formed integrally with the cover 4 and the lamp housing 2. The sealing lips 51, 52 may, as shown, be integrally formed in a part to form the seal 5. It is also conceivable that the sealing lips 51,52 are provided separately to form the seal 5.
    As can be seen in the figures, the lamp housing 2, preferably the transverse wall 7, a circumferential guide web 9 for the cover 4 - or the seal 5 or the web 40 - have. This guide web 9 is preferably located radially inward with respect to the seal 5 and extends toward the light exit region L. Thus, it provides a secure guidance of the cover 4 when inserted into the lamp housing 2 to safely place the seal 5 at the intended position, so that the seal 5 - or the sealing lips 51, 52 - can safely perform their multiple functions.
    The present invention is not limited by the above-mentioned embodiments, as far as it is covered by the subject of the following claims. For example, the positioning and fixing of the seal or its sealing lips 51, 52 are not limited by the present invention, provided that they extend between cover 4 and lamp housing 2 and can fulfill their intended functions safely. The design and dimensions of the luminaire components and seals and the choice of the respective materials are not limited by the present invention.
