Definitions
- the present invention relates to a lamp with a lamp body and a light passage element to be optionally attached thereto, through which light from an illuminant accommodated in the lamp body can pass together.
- Luminaires of the type mentioned are known in principle. Luminaires can be equipped with the appropriate attachments for optical guidance of the light. These attachments are, for example, screwed on or attached to the lamp body by means of fastening means such as screws. When an attachment is screwed on, there is often a risk that it will become detached from the lamp during operation. All the more so when the attachment is a lens, which in turn has rotatable parts for setting or varying a defined light output, the manipulation of which can also affect the connection of the lens to the lamp body.
- Bolted variants are known in which an integrated geometry is intended to prevent loosening. However, this can be skipped if the lamp is in an inclined position (e.g.
- human intervention when used as a spotlight) or if human intervention occurs, and thus cause the attachment to become detached from the lamp body.
- human intervention can be, for example, the turning of the parts to adjust the light output, which is necessary to operate the lamp.
- additional fasteners results in increased assembly and component costs.
- the invention relates to a lamp which has a lamp body for accommodating a light source.
- the lamp body in turn has a light exit opening for the exit of light from the light source accommodated, preferably in a light emission direction.
- the lamp also has a light passage element, which can optionally be mechanically coupled to the lamp body in such a way that the light emitted via the light outlet opening of the light source accommodated can pass through the Light passage element for light emission of the lamp passes.
- the lamp body has a first coupling section and the light passage element has a second coupling section, which interact in such a way that the light passage element can be rotated about an axis of rotation relative to the lamp body between an assembly position, in which the lamp body and the light passage element can be separated from one another, and a coupling position , in which the lamp body and the light passage element are mechanically coupled to one another, is movable.
- the lamp body has a first latching section and the light passage element has a second latching section, which in the coupled position can be latched together in a latching connection such that relative rotatability between the lamp body and light passage element around the axis of rotation is prevented.
- the lamp according to the invention can thus be assembled by means of a rotary movement, ie in particular by means of a screwing movement, in order to mechanically couple the lamp body and the light passage element to be optionally fastened to it.
- latching sections are integrated into the two elements to be coupled, which engage in a latching connection in the coupled position, precisely in order to prevent the two components from becoming detached as a result of a rotary movement about the axis of rotation.
- the axis of rotation can preferably extend along the direction of light emission. A particularly simple structure and intuitive assembly are thus made possible.
- the coupling sections preferably together form a bayonet connection.
- a different type of screw connection is also conceivable.
- corresponding screw connections form a particularly simple and intuitive coupling option.
- a simple structure with an intuitive coupling option can also be provided.
- One of the coupling sections can have a receiving groove running at least partially around the axis of rotation and the other of the coupling sections can have a coupling projection that can be moved in the receiving groove and is guided by the rotary movement.
- This can be, for example, the above-described screw connection or bayonet connection or a different type of corresponding connection.
- This is particularly simple in terms of its structure.
- the lamp can have a plurality of first and second coupling sections, which are preferably distributed uniformly around the axis of rotation. In this way, the security of the coupling connection can be increased. In addition, assembly is made easier. In particular, with an arrangement distributed uniformly around the axis of rotation, a secure and tilt-free assembly and connection can also be made possible.
- the latching connection is preferably detachable. It is thus possible in a simple manner, once the light passage element has been provided, to simply remove it again if necessary and, if necessary, to replace it with another light passage element. This further increases the overall flexibility of the lamp.
- One of the latching sections can have a latching projection and the other of the latching sections can have a latching recess. These are preferably designed in such a way that the latching projection engages in the latching recess in the coupling position to form the latching connection. A simple configuration of the latching connection is thus provided.
- the latching projection can preferably extend radially with respect to the axis of rotation and further preferably protrude toward the axis of rotation.
- the detent recess in turn can preferably extend radially with respect to the axis of rotation and also preferably extend outwards toward the axis of rotation.
- the latching recess is preferably delimited on both sides by latching wall sections, at least as seen in the direction of the rotary movement.
- a secure and defined locking connection can thus be provided in the coupling position.
- the latching sections can also be held securely in the latching connection in the coupling position with respect to the rotary movement.
- At least the latching wall section directed toward the assembly position can have a circumferentially running ramp section in order to guide the latching projection toward the latching projection upon rotation from the assembly position to the coupling position.
- the latching wall section facing away from the assembly position can protrude radially higher than the other with respect to the latching recess with respect to the axis of rotation locking wall section. In this way, it can easily be ensured that when the coupling position is reached, the locking sections securely engage in a locking connection and cannot be rotated beyond the coupling position, since the locking wall section that protrudes higher serves as a kind of stop for the locking projection in the direction of the rotary movement.
- At least one of the latching sections can be prestressed, preferably radially with respect to the axis of rotation, in the direction of the other latching section in the coupling position or in the direction of the latching connection in order to urge into the latching connection in the coupling position. In this way, it is particularly easy to ensure that the locking connection is made in the coupling position between the two locking sections mentioned.
- the latching sections are preferably designed in such a way that the at least one prestressed latching section is deflected counter to the prestressing, preferably radially with respect to the axis of rotation, during rotation from the assembly position to the coupling position, in order to push into the latching connection in the coupling position counter to the deflection.
- the deflection is preferably brought about by guiding over the ramp section.
- the pretensioned locking section can have a spring element in order to correspondingly pretension this locking section.
- the spring element can be a simple spring.
- the spring element can also have an elastically deformable body, such as a rubber element.
- the spring element can also be a resilient pressure piece which has a ball which is accommodated in a housing and protrudes outwards through an opening in the housing in a partially exposed manner. Also carried in the housing is a spring which biases the ball toward the opening. The ball is movable away from the opening into the interior of the housing against the spring force of the spring.
- the prestressed latching section can be movable, counter to the prestress, into a release position, preferably radially with respect to the axis of rotation, in order to allow relative rotatability between the lamp body and the light passage element even in the coupling position; preferably at least towards the assembly position.
- the snap-in connection can be released in a simple manner if required and the light passage element can thus be released from the lamp body by a rotary movement about the axis of rotation counter to a fastening direction.
- the prestressed latching section can have a release section via which an operator can move the prestressed latching section into the release position.
- the release section can be a release projection, for example.
- the latching section can thus be moved into the release position in a simple manner.
- the release section can preferably be provided or protrude outwards through an opening in the part of the lamp body and the light passage element that has the pretensioned latching section and particularly preferably end flush with the part at least in the coupling position. In this way, the release section can be provided in an easily accessible manner. In particular when the release section is integrated flush, unintentional triggering of the release section and thus movement of the prestressed latching section into the release position can be avoided. In addition, a flush integration of the release section can be advantageous for aesthetic reasons.
- the lamp body and/or the light passage element as a fastening part can (each) have a latching element which has one of the latching sections, preferably the prestressed latching section, and also a mounting section for detachable fastening to the fastening part.
- the corresponding locking portion can be provided independently.
- the use of materials advantageous for the snap-in connection can be selected, which can deviate, for example, from the other materials of the fastening part having the snap-in element. An overall optimized lamp can thus be provided.
- the latching element can be mounted pivotably on the fastening part by means of the mounting section. In this way, different positions of the locking element can be easily adjusted. In addition, the assembly of the locking element can be easily enabled.
- the latching element can be fastened to the fastening part via the mounting section in such a way that the latching element can be moved between an installation position in which the latching element can be removed from the fastening part and an operating position in which the latching element holds the latching section in the position for forming the latching connection is. Between these two positions, the latching element can preferably be provided so that it can be pivoted by a defined angle a, this angle a being 90°, for example.
- the latch member can be assembled in a simple manner while at the same time it is provided to be securely fastened in the operative position. Thus, an unintentional release of the latching element can be avoided in particular during the assembly of the components.
- the latching element can preferably be fastened to the fastening part via the mounting section in such a way that the latching section can be moved into the release position as desired. The release position can thus be reached in a simple manner and with a simple construction of the lamp.
- the mounting section and the latching section can be connected to one another via a connecting section.
- the locking element is thus constructed in a simple manner and can be easily produced.
- the latching element can preferably be provided as an aluminum die-cast part or injection-molded part.
- the mounting section can have bearing projections on both sides opposite of the connecting section, which engage in opposite bearing receptacles of the fastening part, viewed in the direction of the rotary movement, for the pivotable mounting of the latching element, preferably about a pivot axis.
- a simple, movable and here preferably pivotable mounting of the latching element can be provided, which also enables a secure movement or pivoting of the latching element.
- the distance between the bearing mounts is preferably selected to be greater than the length of one of the bearing projections and the width of the connecting section together, viewed in the direction of the rotary movement or in the axial direction of the pivot axis. It is thus possible in a simple manner, in order to mount the latching element, to first introduce the latter with one of the bearing projections into one of the bearing receptacles.
- the locking element is slightly tilted, for example. The locking element can then be tilted straight in such a way that the other bearing projection is aligned with the opposite bearing receptacle.
- the other bearing projection can also be inserted into the corresponding bearing mount, so that the latching element is supported securely and firmly—here pivotably—on the corresponding fastening part.
- the fastening part can preferably have a holding section which, in the position for forming the latching connection, preferably in the operating position, delimits the latching element and preferably its connecting section on both sides, seen in the direction of the rotary movement, in such a way that the latching element remains fastened in the fastening part by means of the mounting section (hence ie is not laterally displaceable along the pivot axis) and in this state the associated latching section can also preferably be moved into the release position.
- the holding section can preferably be through in Seen in the direction of rotation opposite holding wall sections of the fastening part can be formed. The latching element is thus held securely on the fastening part, in particular during operation.
- the lamp can also have spring parts which are provided axially with respect to the axis of rotation between the lamp body on the one hand and the light passage element on the other.
- the spring parts can preferably be distributed around the axis of rotation and also preferably distributed evenly.
- it is intended to axially brace the lamp body and the light passage element, at least their coupling sections, at least in the coupling position (with respect to the axis of rotation).
- the lamp also has a lamp, preferably having an LED (light emitting device; light-emitting diode), which is accommodated in the lamp body in such a way that light from the lamp is received via the light exit opening and, if the light passage element is mechanically coupled to the lamp body, also through the Light passage element for light emission of the lamp occurs.
- LED light emitting device
- the use of light-emitting diodes as lighting means enables a cost-effective solution for providing lighting means with a particularly long service life.
- the light passage element can, for example, be a ring, such as a decorative ring.
- the light passage element is any type of optical attachment, such as a lens or an objective.
- the optical attachment can in turn have an optical element such as a lens or a diffuser and the like and also combinations thereof.
- the optical element is particularly preferably provided such that it can be displaced or displaced along the light emission direction or axially along the axis of rotation.
- the optical attachment can have at least two housing parts that can be rotated relative to one another, by a distance between the optical element and the lamp body along the light emission direction or axially along the axis of rotation to change optionally, wherein one of the housing parts has the second coupling portion and the second latching portion and preferably the other of the housing parts carries the optical element.
- the light output of the illuminant can thus be changed or influenced in a simple manner.
- the above-described latching connection also makes it possible, even when housing parts of an optical attachment are provided that can be rotated relative to one another, to stably maintain a mechanical coupling between the lamp body and the light transmission element, which is provided here by means of a screw connection, and to avoid loosening the same, even if the optical attachment is used to adjust the optical light output manipulated by turning.
- the housing elements of the light passage element (such as the aforementioned ring or the housing parts) can be produced, for example, by means of injection molding or die-cast aluminum.

- the figures show an exemplary embodiment of a lamp 1 according to the present invention.
- 2 shows different components for the formation of alternative exemplary embodiments of the lamp 1 according to the invention.
- the lamp 1 has a lamp body 2 for accommodating a light source, not shown in detail here.
- the light source can preferably have an LED or another light source.
- the lamp body 2 has a light exit opening 23 for the exit of light from the light source accommodated in a light emission direction A.
- the lamp body 2 has a cylindrical lamp housing 20 here by way of example. However, other housing shapes are also conceivable. As shown, the lamp body 2 can have a rigid and tubular holder 21 here, via which the lamp body 2 can be carried, preferably rotatably and pivotably, in order to change the light emission direction A.
- the supporting parts or housing elements of the lamp body 2, for example the lamp housing 20 or the holder 21, can be produced, for example, as an injection molded part, sheet metal parts, aluminum die-cast parts and the like.
- the lamp body 2 preferably has a connection element 22 at the end of this holder 21 which is remote from the lamp body 2 .
- the lamp body 2 can preferably be connected electrically and/or mechanically at the place of use via this connection element 22 .
- connection element 22 for the electrical and mechanical coupling is designed, for example, in an elongate support rail.
- the lamp 1 or its lamp body 2 can also have a different design and can be designed, for example, in any form as a built-in lamp, surface-mounted lamp or pendant lamp.
- the lamp 1 also has a light passage element 3, which can optionally be mechanically coupled to the lamp body 2 in such a way that the light emitted via the light exit opening 23 from the light source accommodated passes through the light passage element 3 to emit light from the lamp 1.
- 1 shows the lamp 1 with the lamp body 2 and the light passage element 3 mechanically coupled thereto.
- 2 shows an example of three possible variants of a Light passage element 3 dismantled from the lamp body 2 state.
- the light passage element 3 can be designed, for example, as a ring, such as a decorative ring.
- the light passage element 3 according to the variants in FIG. 2 is designed as an optical attachment, such as a lens or an objective.
- the optical attachment can preferably have an optical element 30, such as a lens or a diffuser.
- the optical element 30 can be provided fixed in the light passage element 3, as shown in the variant at the top left in FIG. It is also conceivable that the optical element 30 can be displaced along the light emission direction A (i.e. when the light passage element 3 is mechanically coupled to the lamp body 2) or axially along the axis of rotation D (cf. Fig. 2; lower variant) or displaced (cf. Fig. 2; variant above middle) is provided.
- the optical attachment can have, for example, at least two housing parts that can be rotated relative to one another. These are, for example, coupled to one another in such a way that by rotating the housing parts relative to one another, they are offset axially with respect to one another. It is also conceivable for the optics element to be suspended in the housing parts in such a way that it is axially displaced relative to one another by rotating the housing parts. Thus, a distance of the optical element 30 to the lamp body 2 along the light emission direction A or axially along the axis of rotation D can be optionally changed.
- the illuminant is accommodated in the lamp body 2 in such a way that its light passes through the light exit opening 23 and, when the light passage element 3 is mechanically coupled to the lamp body 2, also through the light passage element 3 to emit light from the lamp 1.
- An optical element such as a lens, can preferably be arranged in the light exit opening 23 in order to emit the light of the illuminant in a desired manner; preferably in such a way as to direct it into and through the light passage element 3 for the light output of the lamp 1.
- a light mixing chamber can extend between the light exit opening 23 or the lens arranged therein and the illuminant—particularly when LEDs are used as illuminants—in order to homogeneously mix the light emitted by the illuminant.
- the lamp body 2 has a first coupling section 4 and the light passage element 3 has a second coupling section 5 .
- These coupling sections 4, 5 interact in such a way that the light passage element 3 can be rotated by means of a rotary movement about the axis of rotation D relative to the lamp body 2 between an assembly position in which the lamp body 2 and the light passage element 3 can be separated from one another and a coupling position (cf. Figures 1 and 4), in which the lamp body 2 and the light passage element 3 are mechanically coupled to one another, is movable.
- the axis of rotation D preferably extends along the light emission direction A, as is indicated in FIG. 1, for example.
- the coupling sections 4, 5 can together form a bayonet connection.
- One of the coupling sections (here the first coupling section 4) can have a receiving groove 40 running at least partially around the axis of rotation D, as can be seen from the detailed illustration in FIG.
- This receiving groove 40 forms a part of the aforementioned bayonet connection, for example.
- the receiving groove 40 can also be a different type of thread, for example of a conventional design.
- the other of the coupling sections can have a coupling projection (not shown) which can be moved in the receiving groove 40 and is guided by the rotary movement.
- the coupling projection can be, for example, a pin-like protruding element or a counter-thread or the like.
- the lamp 1 can have a plurality of first and second coupling sections 4, 5, which are preferably provided in a uniformly distributed manner around the axis of rotation D. In the exemplary embodiment shown, three such pairs of coupling sections are provided, for example.
- the lamp 1 can also have spring parts (not shown) which are provided axially with respect to the axis of rotation D between the lamp body 2 and the light passage element 3 and preferably distributed around the axis of rotation D (preferably evenly distributed). These spring parts are intended to axially brace the lamp body 2 and the light passage element 3 and at least their coupling sections 4, 5, at least in the coupling position.
- three recesses 24 provided over the circumference of the lamp body 2 are clearly visible in FIG. 3, one of which can also be seen in a side view in FIGS.
- the corresponding spring element can be inserted into these recesses 24 .
- This can be, for example, an element made of an elastic material, such as a rubber stopper, or a resilient pressure piece.
- This spring part then protrudes with a resilient end outwards from the recess 24 and towards the light passage element 3 in the installed position.
- the lamp body 2 also has a first latching section 6 and the light passage element 3 has a second latching section 7, which in the coupled position can be latched together in a latching connection (cf. Fig. 4) such that relative rotation between the lamp body 2 and the light passage element 3 is possible the axis of rotation D around is prevented.
- the latching connection is preferably detachable.
- one of the latching sections can have a latching projection 70 and the other of the latching sections (here the first latching section 6) can have a latching recess 60. These are designed in such a way that the latching projection 70 engages in the latching recess 60 in the coupling position to form the latching connection.
- the latching projection 70 preferably extends radially with respect to the axis of rotation D and preferably protrudes toward the axis of rotation D.
- the two latching sections 6, 7 are preferably of complementary design in order to form a secure latching connection when the two latching sections 6, 7 are coupled.
- the latching recess 60 is preferably delimited on both sides by latching wall sections 61, 62, at least as seen in the direction R of the rotary movement. This ensures secure latching with the latching projection 70 while maintaining the latching connection.
- At least the latching wall section 61 directed towards the assembly position preferably has a ramp section 63 which runs circumferentially and here is directed outwards, ie radially away from the axis of rotation D.
- This ramp section 63 makes it possible to guide the latching projection 70 towards the latching recess 60 during rotation from the assembly position to the coupling position.
- the locking wall section 62 facing away from the assembly position preferably protrudes radially higher with respect to the locking recess 60 with respect to the axis of rotation D (in the present case, therefore, seen outwards with respect to the axis of rotation D, as can be seen, for example, in Fig. 9) than the other locking wall section 61.
- the higher protruding Latching wall section 62 thus forms a stop for latching projection 60, viewed in the direction of rotation toward the coupling position, when latching sections 6, 7 are moved from the assembly position into the coupling position.
- At least one of the latching sections (here the first latching section 6) is preferably biased in the direction of the other latching section (here the second latching section 7) in the coupling position or in the direction of the latching connection. This is preferably radial with respect to the axis of rotation D. This prestress is intended to ensure that the at least one prestressed latching section 6 pushes into the latching connection in the coupling position, so that the latching connection can be securely established and maintained.
- the latching sections 6, 7 are preferably designed in such a way that the at least one prestressed latching section (in this case the first latching section 6) is deflected counter to the prestressing during rotation from the assembly position to the coupling position. This is indicated by way of example in FIG. 5 , the arrow K describing the direction of the deflection and the arrow V the direction of the prestressing force acting on the locking section 6 .
- the deflection is preferably generated by guiding via the ramp section 63 in that the latching projection 70 is supported on the ramp section 63 in a guided manner during a rotary movement of the lamp body 2 relative to the light passage element 3 .
- the prestressed latching section 6 preferably has a spring element 8 in order to correspondingly prestress this latching section 6 .
- the spring element 8 is shown, for example, as a resilient pressure piece.
- the spring element 8 here has a sleeve-shaped housing 80 in which a ball 81 protrudes partially outwards (in Figures 4 and 5 downwards) through an opening 82 of the housing 80 and towards the opening 82 by means of a supported spring 83 is biased.
- the spring element 8 designed as a resilient pressure piece is inserted with the sleeve-shaped housing 80 here in the region of the latching section 6 or in a latching element 9, which will be described below, and is supported on a support section 25 of the lamp body 2 accordingly.
- the ball 81 is shown overlapping the support section 25 in FIG. The ball 81 actually supported on the support section 25 would compress the spring 83 by the amount of the overlap and thus increase the prestressing force in direction V.
- the spring element 8 can also be provided in a different way.
- a simple spring can be provided, or the spring element 8 can be formed of an elastic material such as a rubber block.
- the prestressed latching section 6 can be moved counter to the prestressing into a release position (cf. FIG Lamp body 2 and light passage element 3 to allow in the coupling position (see. Fig. 5); preferably at least towards the assembly position. Due to this mobility into the release position shown in FIG. 5, the latching connection can be released in a simple manner in order to detach the lamp body 2 and the light passage element 3 from one another by a corresponding relative rotary movement towards the assembly position, as is then shown in FIG. 2 by way of example is. In this way, the light passage element 3 can optionally be removed from the lamp body 2 in order to service it, for example, or to replace it with another light passage element 3 .
- the prestressed latching section 6 can preferably have a release section 64, via which an operator can move the prestressed latching section 6 into the release position (cf. FIG. 5).
- the release section 64 can be, for example, a release projection.
- this release section 64 can preferably provide sufficient space to accommodate the spring element 8 in a recess 65 provided therein, as can be seen, for example, in FIGS.
- the release section 64 can preferably protrude or be provided to the outside through an opening 26 of the part having the prestressed latching section 6 (in this case the lamp body 2). At least in the coupling position, the release section 64 is preferably flush with the said part (here the lamp body 2) on the outside, as can be clearly seen in particular from FIGS.
- the lamp body 2 or the light passage element 3 can—then as a fastening part—have the previously mentioned latching element 9 .
- the latching element 9 has one of the latching sections (here preferably the prestressed latching section or the first latching section 6).
- the latching element 9 also has a mounting section 90, by means of which the latching element 9 is fastened to the fastening part (here the lamp body 2); this preferably solvable.
- the latching element 9 is mounted pivotably on the fastening part 2 by means of the mounting section 90, as can be seen, for example, by looking at FIGS. 8 and 9 together.
- the latching element 9 preferably pivots about a pivot axis S of the mounting section 90.
- the latching element 9 is preferably fastened to the fastening part 2 via the mounting section 90 in such a way that the latching element 9 can be switched between an installation position (cf.
- the latching element 9 can also be fastened to the fastening part 2 via the mounting section 90 in such a way that the latching section 6 can optionally (also) be moved into the release position (cf. FIG. 5).
- the assembly section 90 thus offers the possibility of simple assembly as well as reliable, guided mobility of the latching element 9 for clear and defined guidance of the latching section 6, in particular between the operating position (see FIG. 4) and the release position (see FIG. 5). .
- the mounting section 90 can be connected to the latching section 6 via a connecting section 91 of the latching element 9.
- the locking element 9 formed in this way is preferably formed integrally, for example as an aluminum die-cast part or injection-molded part.
- the mounting section 90 can have bearing projections 92, 93 projecting on both sides opposite the connecting section 91, viewed in the direction R of the rotary movement, which can be pivoted in opposite bearing receptacles 94, 95, viewed in the direction R of the rotary movement of the latching element 9, as can ultimately be seen in FIGS.
- the distance X between the bearing mounts 94, 95 can be greater than the length L of one of the bearing projections 92 and the width B of the connecting section 91 viewed together Y in direction R of the rotary movement, as shown in Figures 6 and 7, for example is. In this way, it is possible, as indicated in FIG.
- the fastening part (here the lamp body 2 ) can also have a holding section 27 .
- this holding section 27 can limit the latching element 9 and preferably its connecting section 91 on both sides, viewed in direction R of the rotary movement, in such a way that the latching element 9 is fastened to the fastening part 2 by means of the mounting section 90 remains and in this state particularly preferably the associated latching section 6 can be moved (pivoted here) into the release position (cf. FIG. 5).
- the holding section 27 is preferably formed by two or here also several opposite holding wall sections 28, 29 of the fastening part 2 and, in the operating position of the locking element 9, holds it between them as seen in direction R of the rotary movement, so that a sideways movement of the locking element 9 for releasing the same is blocked .
- Some of the retaining wall sections 28, 29 are here formed adjacent to the bearing receptacles 94, 95 to ensure stable mounting and support over a large pivoting range (towards the operating position and in the operating position) (cf. the respective right-hand ones in Figs. 7-9 ).
- the respective coupling section 4, 5 and/or latching section 6, 7 can be provided on a separate coupling part 10.
- the coupling part 10 can then be mounted, for example, on the lamp housing 20 in order to form the lamp body 2 in this way.
- the light passage element 3 can also be equipped with a corresponding coupling part.
- These coupling parts 10 can be produced, for example, by means of aluminum die casting or injection molding.
- the coupling section 4, 5 and the latching section 6, 7 can also be formed integrally with the corresponding lamp body 2 or light passage element 3.
- the invention is not limited here by the exemplary embodiments described above.
- the housing parts In the configuration of the light passage element 3 as an optical attachment with several mutually rotatable housing parts, it is conceivable that one of the housing parts has the second coupling section 5 and the second latching section 7 and preferably the other of the housing parts carries the optical element.
- the housing parts can be produced, for example, by means of injection molding or die-cast aluminum.
