Definitions
- Damp room luminaire with at least one barrier between a trough-shaped housing and a cover
- the invention relates to a moisture-proof luminaire according to the preamble of claim 1 or 12.
- a moisture-proof luminaire of this type is formed with a two-part overall luminaire housing, one part of which is a trough-shaped housing, the fastening elements for attachment to a carrier, for. B. a wall or a ceiling, and the other part is formed by an at least partially transparent cover, which is detachably connected by closure elements to the trough-shaped housing.
- a carrier for. B. a wall or a ceiling
- the other part is formed by an at least partially transparent cover, which is detachably connected by closure elements to the trough-shaped housing.
- at least one lamp is arranged, which is connected mechanically and electrically, and whose light emitted during operation emits through the transparent cover for room lighting.
- a moisture-proof luminaire of the type specified at the outset is, for. B. described in EP 0 785 391 A1.
- this known light fixture for the cover on the trough-shaped housing are in principle C-shaped closure elements, which are designed as separate components, and of which one end region of the C-shape engages with a locking leg in a pocket-shaped undercut on the trough-shaped housing, over the Gap extends between the trough-shaped housing and the cover and extends with its other end region of the C-shape behind an edge of the cover with a certain tension and thereby compresses the trough-shaped housing and the cover with a certain elastic clamping tension.
- the peripheral wall of the housing branches in the region of the peripheral housing edge with an outer and an inner edge region, which extend transversely to the plane of the housing opening and end at the housing edge.
- the cover has a central edge area that extends like a comb between the outer and the inner edge area at a lateral distance, the edge of the cover extending to the outer edge area and on the end face thereof
- the comb-like interdigitated edge areas form a barrier against the entry of water into the interior of the luminaire, there is a risk that water due to capillary action through the joint between the edge of the cover and the outer edge area between the latter and the middle one Edge area penetrates.
- the invention is based, to improve the protection against the ingress of water in the region of the joint between the housing and the cover in a damp room luminaire of the types specified. This object is solved by the features of claim 1 or 12. Advantageous developments of the invention are described in the associated subclaims.
- the edge region of the cover lies against at least one edge or surface of the groove wall.
- the barrier effect against the ingress of water is improved by the contact of the edge of the central edge region on the outer and / or on the inner taper, because this contact results in a circumferential barrier in the sense of an annular seal.
- Another advantage is that the abovementioned system can form the stops through which the housing and the cover are spaced apart and abut one another in a specific position. Since such a stop extends all around, the contact position is very stable. Special stops between the housing and the cover can thus be omitted, which contributes to simplification.
- the locking web is arranged in the overlap area, wherein it extends from the outer edge area of the housing or from the central edge area of the cover in the direction of the other opposite edge area.
- annular space in the groove opposite the edge region of the cover. This free space can serve to accommodate an annular seal, which enables the dividing joint between the housing and the cover to be sealed.
- the locking web is also advantageous to arrange the locking web at a distance from the edge of the cover that extends along the edge regions. This gives the outer edge area the shape of an effective drip edge.
- FIG. 1 shows a moisture-proof luminaire according to the invention in a perspective bottom view
- Fig. 2 shows the left half of the lamp in vertical cross section and in an enlarged view Presentation
- FIG. 4 shows the parting area according to FIG. 3 in a modified configuration and enlarged view.
- the main parts of the moisture-proof luminaire designated in its entirety by 1 in FIG. 1, are a trough-shaped housing 2, a cover 4 releasably connected to it by a plurality of closure devices 3 arranged around the circumference, and a cover 4 in the cavity 5 between the trough-shaped housing 2 and the cover 4 arranged lamp 6, which is connected and held to at least one mechanical and electrical connecting element, not shown.
- the closure devices 3 are present in all exemplary embodiments.

- This protection can be in the area of the parting line 7 by overlapping and z. B. comb-like, interlocking and circumferentially extending edge regions of the housing 2 and the cover 4 be splash-proof.
- the edge areas can e.g. B. be formed by web walls 8a, 8b, 8c, which form a labyrinth that offers protection against the ingress of splash water.
- the trough-shaped housing wall 2a branches in its free edge region to two web walls 8a, 8b, which have a transverse distance from one another that is greater than an edge region 8c of the edge region of the cover 4, which encloses a transverse distance between the edge regions 8a, 8b.
- the edge regions or web walls 8a, 8b, 8c project transversely to the division joint 7 or transversely to the plane of the housing opening from the housing wall or from the edge region of the cover 4.
- the division joint 7 can preferably be sealed in addition to the labyrinth by an annular seal which has a sealing ring D which, for. B. is arranged in the base of the circumferential groove 2b present between the web walls 8a, 8b, and against which the web wall 8c presses.
- the sealing ring D is made of soft material, e.g. B. from a foam tape.
- the outer wall web 8b of the housing wall 2a is part of a widening step 9 in the free edge region of the housing wall 2a.
- the housing wall 2a has on its one carrier, for. B. a ceiling or wall of a room, facing plant side 11 fasteners 12, which are used for attachment to the carrier.
- the lamp 1 has an elongated and straight shape, the length L1 of which is a multiple of its width B.
- the housing 2 and the cover 4 were shaped accordingly. This consists at least in their housing 2 facing away, z. B. domed area or in the embodiment as a whole of a transparent material, for. B. glass or plastic through which the light of the lamp 6 in the main emission direction S but also radiates to the sides.
- the closure device 3 has a closure element 3a in a basically C-shaped longitudinal cross-sectional shape, the end regions of which are designated 3 b, 3 c, the upper end region 3 b engages behind the trough-shaped housing 2 and at the same time, preferably by clamping, engages in a pocket 13 in the housing 2, which is open to the side facing away from the division joint 7, and with two opposing pocket walls 13 a, 13 b, which extend approximately parallel to the longitudinal central plane 15, with or without undersize to the size of the end region 3 b is adjusted.
- the recess 13 can extend continuously in the longitudinal direction of the lamp 1.
- the closure element 3a extends from the end region 3b essentially in a shape adapted to the associated outer shape of the housing 2 on the outside of the lamp housing toward the cover 4, it extending beyond the dividing joint 7 and with the associated end region 3c a widening step 10 at the Cover 4 engages behind, optionally engages in a recess 10a formed thereon.
- the latter is done with an angled or curved inward extending rear gripping leg 3d forming the end region 3c, which is secured in its rear gripping position by a securing device 14.
- the securing device 14 can be formed in that the rear gripping leg 3d is elastically prestressed obliquely inwards against the widening shoulder 10 with respect to the longitudinal center plane 15 of the lamp 1 extending transversely or at right angles to the dividing joint 7, so that this tension forces it inwards and not outwards pulls.
- This is achieved in that the rear grip of the end region 3 c is arranged at a distance a from the longitudinal central plane 15, which is greater than the distance b of the rear grip of the end region 3b from the longitudinal central plane 15 an elastic tension on the widening step 10, the rear gripping legs 3d have a tensioning force 16, the effective direction of which includes an acute angle W1 with the longitudinal center plane 15.
- This tensioning force can be based on an elastic bending of the end region 3b and / or the end region 3c and / or the shape of the closure element 3a following and widening the widening step 9 with respect to the step shape.
- the closure element 3a is formed by a web 3e extending flatly over its entire length, the thickness of which is denoted by d.
- the end region 3b of the closure element 3a projecting in a hook shape towards the free end region 3c can be arrested by a locking device 17 in the pocket 13 against unwanted pulling out and thus loosening.
- the lock can, for. B. based on a transverse to the end portion 3b and against the side walls of the pocket 13 effective clamping action.
- a securing of the end region 3b in the pocket 13 can thus be ensured, which prevents the closure element 3a from being unintentionally released and lost.
- the transverse dimension of the groove 2b is greater than the thickness of the central web wall 8c, which results in a distance c between the inner web wall 8a and the middle web wall 8c and a distance d between the outer web wall 8b and the middle web wall 8c.
- the distances c, d result circumferential annular gaps between the comb-like web walls 8a, 8b, 8c.
- FIGS. 3 and 4 constructions are shown which are intended to and may make it more difficult or prevent barriers against the ingress of water from outside through the division joint 7.
- the first construction is arranged at a distance d or overlap area between the outer web wall 8b and the central web wall 8c and, according to FIGS. 2 and 3, is formed by a barrier web 19 which projects from one of the two web walls 8b, 8c transversely to the opposite web wall and protrudes from the central web wall 8c to the outer web wall 8b in the exemplary embodiment.
- the locking web 19 is preferably arranged in the foot region of the inner web wall 8c. It has proven to be particularly advantageous to arrange the locking web 19 at a distance e from the free edge of the outer web wall 8b, this dimensioning relating to the mounting position of the housing 2 and the cover 4.
- the ring height f of the barrier web 19 extending parallel to the distance d is somewhat smaller than the distance d, so that there is an annular gap or distance g between the barrier web 19 and the opposite inner surface of the web wall 8b, which gap is preferably less than half the distance d.
- the shoulder surface of the barrier web 19 facing away from the free edge of the outer web wall 8b is preferably inclined towards the free edge of the outer web wall 8b.
- the inner web wall 8a can be made shorter than the outer web wall 8b, which saves material and weight.
- two mutually independent constructions are provided for improving the resistance to the ingress of water.
- a second construction is a modification of the first construction 1, wherein a barrier web 19a instead of the central web wall 8c protrudes from the outer web wall 8b to the central web wall 8c.
- the z. B. from the middle wall web 8c projecting locking web 19 may have a converging cross-sectional shape towards its free end, which according to FIG. B. is sawtooth-shaped, the side surface facing in the free edge of the central web wall 8c is inclined with respect to the vertical central plane 15, while the side surface facing away from the free edge of the web wall 8c runs approximately at right angles to the vertical longitudinal center plane 15.
- Such a cross-sectional shape and configuration results in a locking web 19 in the form of a sealing lip which, if it is dimensioned so long that its free edge lies against the respectively opposite web wall, when the housing 2 and the cover 4 or the web walls 8a are plugged together, 8b, 8c is bent elastically without hindering the plugging together and performs a sealing function due to its elastic restoring force.
- FIG. 4 shows by way of example that two locking webs 19a, 19 can be arranged one behind the other and can protrude from the web walls 8b, 8c lying opposite one another.
- the preferably elastically insertable and extractable locking web 19 can be arranged behind the non-deployable and extractable locking web 19a, the latter performing the function of a locking element and z. B. may have a small dimension h, the z. B. is less than half the distance d.
- the locking web 19a can thus be formed by non-circumferential locking elements, which can consist in the circumferential direction of a plurality of circumferential sections arranged one behind the other, for. B. from circumferentially spaced cams arranged z. B. have a round cross-sectional shape visible in FIG. 4 or a hemispherical cross-sectional shape.
- a spacing d forms a first chamber 22a within the barrier web 19 in the form of a sealing lip if a sealing ring D is provided or the second construction is provided.
- the second construction which can be provided in combination with the first construction in the exemplary embodiment according to FIG. 4, has on the inside on the outer web wall 8b a taper 23a of the groove 2b, which is formed by a convergent boundary surface 23c of the outer web wall 8b, wherein the middle web wall 8c rests against the taper 23a in its free edge area, preferably with a boundary surface 8d, which is also convergent towards its free end, and forms an annular seal. If the middle web wall 8c is additionally supported on the inside on the inner web wall 8a, an adequate seal can be achieved with the middle web wall 8c by a linear or planar contact of the free end region of the middle web wall 8c.
- the inner web wall 8a opposite the taper 23a can also have a taper 23b which is delimited by a convergent boundary surface 23d against which the middle web wall 8c rests, preferably also with a convergent boundary surface 8e.
- the boundary surfaces 23c, 23d, 8e, 8d are preferably symmetrical with respect to the central axis of the central web wall 8c.
- a small distance i is preferably present between the central web wall 8c and the inner web wall 8a, in order to ensure a play of movement during assembly or disassembly.
- the convergence of the taper 23a can be formed in that the outer web wall 8b extends converging overall in the associated wall area, preferably obliquely, as shown in FIG. 4.
- a sealing ring preferably made of elastic material, can optionally be arranged in the base of the groove 2b, against which the free edge of the central web wall 8c presses, thereby additionally sealing the dividing joint 7 thus formed is.
- a comparable sealing ring can also be used in the second Chamber 22b be arranged and cooperate with the free edge of the central web wall 8c.
- the housing 2 and the cover 4 are preferably made of plastic, wherein they are each made in one piece by injection molding with the associated web walls 8a, 8b, 8c and the one or more locking webs 19.
