Definitions
- the present invention relates to an optics system for lights with an optics carrier serving to accommodate optics elements, as well as a lighting system with a light and an optics system of the prescribed type placed on top of it.
- Luminaires and optics that can be used for them are known in principle. By means of the optics, a defined light emission characteristic of the lamp should be provided and, if necessary, be able to be changed. In a simple variant, certain optical elements, such as lenses and associated diffuser disks, are fixedly mounted at various fixed distances from the light source in order to obtain a desired light image. In order to get a different light image, different optics must be used in this lall.
- solutions are also known in which the optical elements are provided so as to be adjustable with respect to the light source.
- solutions of any complexity for the electrical or mechanical adjustment of the optical elements are known, which generally require the use of a new lamp that has this technology installed.
- the present invention relates to an optical system for lights.
- This has an optics carrier or a carrier housing.
- the optics carrier extends in a straight line along a longitudinal axis between a light entry opening and a light exit opening.
- the optics carrier is or preferably extends in the form of a tube and particularly preferably has a cylindrical shape.
- the optics carrier limited between the Openings i.e. the light entry opening and the light exit opening
- An inner wall of the optics carrier directed toward the receiving space has at least two or a plurality of structural sections arranged axially offset relative to one another with respect to the longitudinal axis, each for detachably holding one of the optics elements in the receiving space.
- any desired light image can be generated using arbitrarily selected optical elements.
- any optical elements can be selectively inserted into any of the positions that are axially offset from one another in the structural sections. Since these structural sections are provided axially offset from one another along the longitudinal axis, any optical element or any combination of optical elements can be arranged at the desired axial distance from the light source or luminaire, or the optical elements can also be provided at any desired distance from one another depending on the number of structural sections - so arranged in series with each other - are.
- a beam angle can be varied (reduced or extended) along the longitudinal axis (thus achieving a zoom effect) and/or the sharpness of a light cone in the edge area can be optionally softened by providing them differently along the longitudinal axis, in order to achieve so-called "beam shaping". “-Effect to achieve or to make the edge area either sharp-edged (more) or soft (er).
- a wide variety of light images can be generated in this way, while the overall structure of the optical system is particularly simple and its provision is made possible in a cost-effective manner. Due to the detachable mounting of the optics elements, an adjustment of the light image can also be easily implemented, so that the handling of the optics system is particularly easy overall.
- the structural sections can preferably each be provided circumferentially along the inner wall and preferably in a plane perpendicular to the longitudinal axis or extend accordingly.
- a secure positioning of an optical element can be achieved by correspondingly defined structural sections that are preferably clearly aligned with respect to the direction of light emission.
- the structural sections can have regions distributed around the circumference or can extend in a closed manner around the circumference. Depending on requirements, a desired mount for the optical elements can thus be provided. While an arrangement of the structural sections distributed around the circumference requires less material and less coverage of the optical elements, a closed arrangement on the circumference makes it possible Design of the structural sections an all-round secure support or storage of an optical element and an overall stable design of the support housing.
- the structural sections can each have groove sections which extend around the longitudinal axis and are open radially with respect to the longitudinal axis towards the receiving space. In this way, the optical elements can be securely inserted into precisely these groove sections in a particularly simple manner and thus optimally mounted with respect to the longitudinal axis.
- the groove sections can preferably be designed as annular grooves, which are preferably designed to be closed all the way around the longitudinal axis. Ring grooves not only form a particularly secure and stable mount for the optics element, but also allow an operator to attach the optics element intuitively.
- the circumferentially closed design increases the overall stability of the carrier housing, so that it can be designed with less material use due to the structuring, which in turn is reflected in a more cost-effective production.
- the groove sections preferably widen radially with respect to the longitudinal axis and toward the receiving space. In this way, a safe introduction of the optical element into the groove sections is made possible. In addition, certain tolerances can be compensated in this way; this both with respect to the longitudinal axis in the radial and in the axial direction.
- a corresponding optical element to be accommodated can be provided with a defined oversize, which is then inserted into the outwardly tapering groove sections and thus pressed in and thus held securely.
- the structural sections can be provided at least in part equidistantly along the longitudinal axis.
- the optical elements can be arranged in defined, fixed and preferably uniform steps as desired at different distances from the light entry opening or the light exit opening and thus a light provided with the optical system. This is particularly advantageous in the case of an optical system with a large number of structural sections, since in this way a light emission characteristic can be adapted, preferably linearly.
- the optics carrier can have a round or polygonal cross section.
- the round configuration enables particularly simple production.
- a polygonal cross-section can, for example, serve to prevent the optical elements from rotating relative to the carrier housing if the optical elements are designed accordingly. This can also be advantageous for aesthetic reasons.
- the grip of the carrier housing can be increased by a polygonal cross-sectional shape.
- the carrier housing itself can also be accommodated in a preferably non-rotatable manner in relation to other components, as is described below by way of example with a view to a system housing.
- the optics carrier can preferably be tubular or cylindrical.
- the optics carrier is thus designed to be simple in structure with a high degree of functional flexibility.
- the optics carrier and at least its inner wall can be mirror-symmetrical with respect to a mirror plane having the longitudinal axis. On the one hand, this is advantageous in terms of manufacturing technology. A simple and clear structure can also be provided in this way, which in turn enables intuitive operation of the optical system.
- the optics carrier can preferably be composed of (at least) two partial elements.
- the partial elements are particularly preferably (at least) two half-shell elements.
- a parting plane of these partial elements preferably has the longitudinal axis.
- a particularly simple construction of the carrier housing can thus be provided.
- the provision of the carrier housing in separable partial elements also enables a particularly simple insertion of the optics elements into the open optics carrier, which is then closed in a particularly simple manner by joining these two partial elements.
- a separable or divisible configuration and function of the sub-elements enables the optical elements to be easily inserted and/or changed at any time, in that the receiving space and thus the structural sections can be easily uncovered by this separation.
- the partial elements can particularly preferably be identical.
- the use of identical parts in turn has an advantageous effect on cost-effective production of the same. Only one tool is required to produce the entire carrier housing. Incorrect installation can also be avoided in this way.
- the sub-elements can each have coupling structures in order to connect the sub-elements to one another.
- the connection is preferably detachable.
- the connection can also preferably be made without tools.
- a simple and stable connection of the sub-elements can be provided. Since these are also preferably provided outside the receiving space, they collide neither with the structural sections nor with any optical elements that are to be received.
- the coupling structures are thus outside of one Light passage distance, so that they - for example due to shading - do not have a negative effect on the light image.
- the coupling structures can also be provided on the face side in connection areas of the sub-elements lying in the parting plane, so that they are provided completely hidden in the assembled state.
- the coupling structures are preferably provided on an outer wall of the carrier housing facing away from the receiving space.
- the partial elements can be connected to one another in an articulated manner via a joint section around a pivot axis in order to pivot the partial elements relative to one another and thus selectively uncover the receiving space for inserting the optical elements into the structural sections.
- an articulated section enables the partial elements to be handled in a manner that prevents them from being lost.
- a defined positioning of the partial elements relative to one another is automatically provided. Overall, the handling during assembly or adjustment of the light image is thus simplified.
- the coupling structures can have the joint section (or vice versa).
- the coupling structures can be designed in such a way that they are provided, for example, on two opposite sides with respect to the longitudinal axis on the carrier housing or the partial elements. If the coupling structure is separated on one of the sides while it is maintained on the other side, the coupling structure on the same other side can be used as a joint section.
- one sub-element in a coupling structure has a projection (e.g. pin or pin) extending parallel to the longitudinal axis and the counterpart of the coupling structure on the other sub-element has a corresponding recess (e.g.
- two coupling structures can be provided on each side of the carrier housing, axially offset along the longitudinal axis, which have protruding projections directed in opposite directions or towards one another, which engage in correspondingly provided recesses (i.e. e.g. directed towards or away from each other).
- an overall safe coupling of the sub-elements can be provided, while the coupling structure can be used at the same time in a particularly simple manner, optionally as a joint section.
- the pivot axis particularly preferably runs parallel to the longitudinal axis.
- a particularly simple pivoting of the partial elements can thus be made possible. This is given in particular when, as described above, the coupling structures have the articulated section.
- the optics carrier or its partial elements can be produced as an injection molded part.
- the optics carrier can thus be provided in a particularly simple manner.
- the separate variant of the optics carrier in two or more sub-elements enables particularly simple production here, since demoulding of these components after the injection molding process is particularly simple and non-destructive with regard to the injection mold, especially when the structural sections are designed in the form of grooves.
- an overall cost-effective production of the carrier housing can be made possible.
- the optics system can also have a system housing for accommodating the optics carrier, which surrounds the optics carrier on the outside on the peripheral side.
- the optics carrier can thus be used as a type of cartridge which can be inserted into the system housing in a simple manner after the optics elements have been accommodated in the desired structural sections.
- additional coupling structures may be omitted, since the optics carrier is preferably held together by the system housing.
- the optics carrier can be inserted into the system housing along the longitudinal axis. Such an axial insertion enables the optical system to be assembled in a particularly simple and at the same time secure manner. A subsequent adjustment of the light image by moving the optical elements can also be made possible in a simple manner by simply pulling the optics carrier out of the system housing, moving the optics elements and pushing the optics carrier back in.
- the system housing and the optics carrier or the carrier housing can have corresponding connection structures on the sides facing one another (ie the side of the optics carrier directed radially outwards and the inside of the system housing directed radially inwards). These can guide the housings during insertion along the longitudinal axis, preferably relative to one another, or they can guide the optics carrier during insertion along the longitudinal axis relative to the system housing. More preferably, the connecting structures can be designed in such a way that they prevent the housings (ie the system housing and the carrier housing or optics carrier) from rotating relative to one another about the longitudinal axis. This enables simple and reliable installation with a defined alignment of the housings to one another. Incorrect installation can also be avoided by appropriate design of the connection structures, for example by providing and/or designing the connection structures asymmetrically are and only a clear assignment - so with respect to the longitudinal axis circumferential orientation to each other - allows assembly.
- the system housing can also have two holding sections, which hold the optics carrier axially between them and particularly preferably clamp it.
- the holding sections can preferably be provided on the opposite ends of the optics carrier axially with respect to the longitudinal axis.
- the holding sections can preferably be webs that protrude radially inwards with respect to the longitudinal axis.
- the respective holding section can have an annular projection that protrudes radially inward in the form of a ring.
- One of the holding sections can be detachably provided on/in the system housing.
- the optics carrier can thus be exposed axially in a simple manner, for example by removing this detachable holding section, in order to remove the optics carrier for the purpose of adjusting the light image, for example.
- the releasably provided holding section can be attached, for example, by a rotary movement; For this purpose, it can preferably have a corresponding screw or bayonet structure, which is designed to correspond with a corresponding counter-structure on the side of the system housing.
- the optics system can also have an attachment which is preferably detachable on the side facing the light exit opening and is provided in such a way that light emitted via the light exit opening passes through the attachment for light emission from a lamp equipped with the optics system.
- the attachment can be designed in any way and be designed and provided, for example, to fulfill aesthetic, optical, manufacturing or static tasks. For example, in the simplest embodiment, it can be a simple decorative ring. It can also be a designed lamp attachment. It can also be an attachment that defines the light cone, for example.
- the attachment may also include optical features such as a reflector.
- the attachment can also be made of a reflective material, for example.
- the attachment can have one of the holding sections. This is particularly useful for the detachable version.
- the structure of the optical system as a whole can be simplified.
- a light image can also be adjusted overall in a particularly simple manner in that the optics carrier is exposed by automatically removing the attachment together with the holding section, and the optics elements can thus be adjusted can be removed.
- the attachment can then be exchanged, if required and without additional installation effort. After inserting the optics carrier and putting on (e.g. screwing on) the attachment together with the holding section, the optics system is then ready for operation again.
- the attachment can be provided on the optics carrier or, if present, on the system housing.
- the optics system is therefore of particularly simple design and the attachment of the attachment can be effected in a simple manner.
- the attachment can preferably carry an optics part (for example a lens or a diffuser) in a preferably detachable manner and in such a way that the light passing through the attachment at least partially passes through the optics part for optically influencing the light.
- the optical function of the optical system can be expanded with the attachment.
- the optics system On its side facing the light entry opening, the optics system can have a fastening section for fastening the optics system to a lamp in such a way that light from the lamp passes through the optics system along the longitudinal axis first via the light entry opening and then through the light exit opening.
- a simple attachment of the optics system to a lamp can be provided. Since this is also provided on a side facing the light entry opening, a corresponding luminaire can be provided in an optimized manner with regard to the optical system and preferably close to the light entry opening. A particularly compact design can also be achieved in this way.
- the fastening sections can be provided on the optics carrier or, if present, on the system housing. An overall particularly simple design of the optical system can thus be provided.
- the fastening section can preferably have a thread or part of a bayonet connection in order to fasten the optical system preferably by relative rotation about the longitudinal axis.
- An equally intuitive and secure attachment of the optical system can thus be provided. This can also be operated intuitively by an operator, thus reliably avoiding Lehle installation.
- the optical system can also preferably have at least one optical element, as has already been described above.
- the optical element is then inserted into one of the structural sections so that it can be removed in such a way that a light that is coupled via the light entry opening and light that is coupled out again via the light exit opening can use the optical element for the optical Influencing the light at least partially and preferably completely passes through.
- the optics element preferably extends transversely or perpendicularly to the longitudinal axis over the entire recording space in order to be arranged in a safe and defined manner in the light path.
- a corresponding optical element can be provided in any desired and particularly simple manner for the defined setting of a desired light image.
- the optical system can preferably have at least two optical elements, each of which is inserted in one of the structural sections in such a way that they are spaced apart from one another when viewed axially with respect to the longitudinal axis (i.e. in a row with respect to one another with respect to the longitudinal axis) in such a way that via the Light coupled into the light entry opening and coupled out again via the light exit opening passes through the at least two optical elements for optically influencing the light at least partially and preferably completely.
- a combination of optical elements can thus be provided in a simple manner and a light image can be varied in a defined manner by variations of their relative axial distance from one another with respect to the longitudinal axis.
- the optics elements particularly preferably have a peripheral contour on the outside, which corresponds to the contour of the optics carrier in the area of the structural sections. A defined alignment and a secure fit of the optics elements in the optics carrier can thus be ensured. A desired light pattern can thus be achieved particularly precisely and also maintained during the period of operation.
- the optics elements can be clamped at least partially or closed on the outside circumferentially by the optics carrier radially with respect to the longitudinal axis in order to ensure a particularly firm and secure fit of the optics elements.
- the optical elements can be selected from at least one from the group of lenses, such as lens lenses, or diffuser disks, such as diffuser disks, and the like.
- the invention is not limited to any specific optical element here. By providing one or more optical elements at any distance from a light source and relative to one another if there are several optical elements, countless light emission characteristics or light images can be made possible using this optical system. This is all the more the case if an attachment provided on the light exit opening is also provided with corresponding further optical parts.
- the optics system is arranged in relation to the lamp and these are preferably connected to one another via the fastening section such that light from the lamp first passes through the optics system via the light entry opening and then the light exit opening for light emission from the lighting system.
- any desired light image can be generated, which in turn can be adjusted in a particularly simple manner by exchanging the optical elements in type and/or sequence and/or position with respect to the structural sections and thus the lamp or be adjusted.
- the lamp can be any type of lamp that can be equipped with a corresponding optical system.
- it can be a spotlight or spotlight or a downlight and much more.
- It can also be a surface-mounted lamp, recessed lamp, pendant lamp, floor lamp, table lamp and much more.

- the figures show two exemplary embodiments of a lighting system 1 according to the present invention or individual components thereof.
- Figures 1 to 3 and 6 show a lamp S as part of the lighting system 1.
- FIG. 4 also shows an optics system 2 of the lighting system 1 (in FIG. 3 only a part thereof), which also represents an independent part of the present invention and is therefore initially described below.
- the optics system 2 for lights S has an optics carrier 3 .
- This extends in a straight line and here preferably in a tubular or cylindrical manner between a light entry opening LE and a light exit opening LA along a longitudinal axis A.
- the optics carrier 3 delimits a receiving space R between the openings LE, LA for accommodating optical elements 4, 5.
- the optical elements 4 , 5 can be, for example, a lens 4, such as a Frensel lens, or a diffusing disk 5, such as a diffuser disk, and the like.
- an inner wall 30 of the optics carrier 3 directed towards the receiving space R can have at least two structural sections 31 which are arranged axially offset relative to one another with respect to the longitudinal axis A, each for the detachable mounting of an object element 4, 5 in the receiving space R .
- a total of twelve such structural sections 31 are provided in the illustrated exemplary embodiments. These are also provided here with a unique numbering (here 1 to 12; cf. FIG. 5) in order to ensure error-free insertion of the optical elements 4, 5 at defined positions in order to achieve a desired light image.
- the structural sections 31 can each be provided or extend circumferentially along the inner wall 30 and preferably in a plane perpendicular to the longitudinal axis A, and thus, as can be seen in FIGS. 2, 5 and 6, form uniform structures.
- the structural sections 31 can each extend around the longitudinal axis A, as can be seen, for example, in FIG. 1 . This can be made possible, for example, by providing the structure sections with structure areas distributed over the circumference or, as shown in the exemplary embodiment, by a structure that is closed all the way round. Consequently, the structural sections 31 can have groove sections which are open radially with respect to the longitudinal axis A towards the interior 30, such as these in particular in FIGS.
- the groove sections can, as shown, be designed as annular grooves, which preferably—as here—are designed to be closed all the way around the longitudinal axis A.
- the structural sections 31 thus form a particularly secure receptacle for the optical elements 4, 5, as will be described below.
- the groove sections can expand radially with respect to the longitudinal axis A and towards the receiving space R. Consequently, the groove sections form a kind of guide bevel in order to enable particularly simple insertion of the optics elements 4 , 5 and preferably also to accommodate any play between the optics element 4 , 5 and the optics carrier 3 .
- the structural sections 31 can be provided at least in part along the longitudinal axis A, preferably equidistantly, in order to enable a defined and uniform adjustment and therefore positioning of the optical elements 4, 5, preferably to achieve a (preferably linear ) to allow change of a light emission characteristic.
- the optics carrier 3 can have a round cross section. This can be provided in a particularly simple manner in terms of manufacturing technology.
- Other cross-sectional shapes are also conceivable, such as polygonal cross-sectional shapes of any kind, such as quadrangular, pentagonal, hexagonal, octagonal, square, rectangular, etc.
- the optics carrier 3 or, as can be seen for example from FIGS.
- the optics elements 4, 5 can thus be accommodated in a particularly simple manner and the optics carrier 3 can be produced easily.
- the optics carrier 3 can be composed of two or more partial elements 32 here.
- the partial elements 32 can preferably be half-shell elements.
- a parting plane of the optics carrier 3 for forming or separating the partial elements 32 can preferably have the longitudinal axis A, as can be derived from FIGS. 4 and 5, for example.
- the partial elements 32 are preferably of identical design.
- the production of the same and thus of the optics carrier 3 as a whole can therefore be carried out particularly easily and with little use of tools.
- the partial elements 32 can each have coupling structures 33, 34 in order to connect the partial elements 32 to one another.
