    ADJUSTABLE OPTICAL SYSTEM
    The invention relates to a lamp with an adjustable optical system for adjusting an optic relative to a light emitting area.
    By means of an additional spring element F (for example, a spring made of spring steel), it is known from the prior art to couple several optics together in such a way that by means of a relative movement between the two optics, for example by means of a positioning ring S - the distance between the two optics and the optics with respect to the light source (in particular an LED) can be changed so as to vary the light path of the lamp (see Figure 1).
    It has now been found in the prior art that the known systems are complicated in their production and limited in their function.
    Starting from the known prior art, it is now an object of the present invention, the previously known systems in particular manufacturing technology and functional, e.g. with regard to recovery, sealing and adjustment properties.
    This object is solved by the subject matter of the independent claims. The dependent claims further form the central idea of the invention in a particularly advantageous manner.
    To solve this problem, the invention according to a first aspect of the invention relates to a luminaire with optical system, in particular for radiator optics with adjustable Lichtabstrahlwinkel and / or adjustable lens arrays (eg straight line of light and individual adjustment as a wallwasher function), provided which an optical element of the optical system (For influencing light by means of its optical range), a light emitting area for receiving a light source, which cooperates optically with the optical element, a manipulation element for relative change in position of the optical element with respect to the light emitting area, and a spring element, which is designed such that it in the relative position change of the optical element exerts a restoring force on the optical element. The invention is characterized in that the spring element is integrally formed with the optical element. The fact that the spring element with the optical element is now integrally formed, the number of functional parts and thus the manufacturing and assembly costs can be reduced, without the functionality, such. the provision to the original optic position to restrict the luminaire. In the context of the invention, "optical system" is understood to mean the one or more optical elements or elements that together determine the emission characteristic of the luminaire.
    Preferably, the manipulation element is designed such that it causes the relative change in position of the optical element by a rotational movement. Thus, a simple relative change in position of the optical element is provided by the simple rotational movement.
    In order to effect a desired optical effect between the optical element and the light emitting area in a simple manner, the manipulation element may also be designed such that it causes the relative change in position of the optical element substantially along an axis connecting the light emitting area with the optical element. A "connecting axis" is understood here to mean, in particular, a straight line connecting the two elements or regions (for example, perpendicular to the plane spanning the elements / regions), which may be congruent, in particular, with a light axis or optical axis of a light source to be provided.
    Preferably, the manipulation element is designed such that it causes the relative change in position of the optical element additionally or alternatively substantially transversely to an axis connecting the light emitting area with the optical element. By changing the position transversely to the axis connecting the light emitting area with the optical element, a further degree of freedom is provided, so that an additional optical effect can be effected between the optical element and the light emitting area; so the radiation characteristic can be set / changed as desired.
    The optical element is preferably formed (under "trained" is in the context of the invention, in particular designed and intended) that it can be tilted by the relative position change with respect to the light output by the manipulation element. Due to the tilting of the optical element with respect to the light emitting area, the radiation characteristic can be selectively adjusted / changed, in particular with respect to the emission direction.
    The spring element may be at least fixed with its free end relative to the light emitting region and / or the light emitting region facing the end of the optical element may be substantially fixed pointwise relative to the light emitting area, whereby by a change in position of the optical element with respect to the light emitting area a particularly simple tilting of Optical element is provided around the fixed area / point as a hinge relative to the light emitting area. By "selectively fixed" in the context of the invention is meant a connection of the corresponding elements, which is designed such that it allows a pivotal pivoting movement about this point.
    Preferably, a translation element is further provided, which is designed such that it can translate the rotational movement of the manipulation element in a translational movement particularly preferably transversely to and / or along an axis connecting the light emitting area with the optical element axis, so that the relative change in position of the optical element can be made with respect to the light emitting area and / or the optical element with respect to the light emitting area can be tilted. By the translation element thus a simple mechanical solution is provided to translate the rotational movement of the manipulation element to a translational movement for relative change in position of the optical element.
    The translation element may also be an eccentric, whereby in particular a translation element for the optical system is provided, which is both easy to manufacture and easy to assemble.
    Preferably, the manipulation element can also be designed such that its rotational movement is a screwing movement about an axis connecting the light emitting area with the optical element. As a result, a particularly simple and space-saving manipulation element is provided in order to change the optical element in its position.
    Further, a second optical element may be provided for the lamp, wherein the second optical element is held by the spring element of the first optical element in a position relative to the light emitting area. An advantage of this embodiment is in particular that both the first optical element can be reset by the restoring force to its original position by the spring element and the second optical element can be held in position, whereby the assembly cost can be further reduced. The second optical element may alternatively or additionally also be formed in accordance with the first optical element, whereby the advantage is obtained that by manipulating the first optical element only both the position of the first and the position of the second optical element can be changed to e.g. to cause an optical effect between the optical elements and the light emitting area. Alternatively, it is also conceivable that the second optical element interacts with its spring element with the spring element of the first optical element, while the second optical element is held in position relative to the light emitting area, that the relative change in position of the first optical element with respect to the light emitting area via both spring elements can take place. By interaction of the spring elements of the optical elements can in particular be effected that the spring constant of the optical system is changed without changing the spring elements of the optical elements themselves, which in turn reduces the manufacturing and assembly costs.
    Preferably, the manipulation element has a support on which at least one or more of the optical elements is resiliently received by means of the spring elements / are. A particularly simple construction for a multiplicity of the optics according to the invention is thus provided, in order, in addition to the change in the emission characteristic, in particular also by the spring elements, to effect a tolerance compensation with respect to the illuminants associated with the optics elements.
    To simplify the production of the carrier with the one or more optical elements and to save additional assembly steps, the carrier may also be integrally formed with the one or more optical elements.
    The material of the optical element may be an optical silicone, which in addition to the optical properties of the material and in particular the mechanical properties can be advantageously used for the optical system, in particular for the spring elements.
    The optical element may be an auxiliary lens and / or light-directing lens. Moreover, the invention is not limited to any particular type of optics or lens.
    According to a second aspect, the invention relates to a luminaire with optical system, comprising an optical element, a light emitting area for receiving a light source, which optically cooperates with the optical element, a positioning element for the defined positioning of the optical element, and a spring element, which is designed such in that it fixes the optical element in the defined position by means of a restoring force of the spring element on the positioning element. The embodiment is characterized in that the spring element is integrally formed with the optical element. Characterized in that the spring element is formed integrally with the optical element, the manufacturing and assembly costs can be kept low, since the number of functional parts is reduced. Furthermore, it can be ensured by the spring element on the positioning that the optical element is installed in the defined position, whereby the assembly cost can be further reduced. The positioning element can be a stop or a different type of receptacle (for example in the form of a projection or a receiving groove) or else an adjustable manipulation element, as has already been described above. Incidentally, all the features mentioned with respect to the first aspect are equally applicable to the second aspect of the invention.
    According to a third aspect, the invention relates to a lighting system, comprising a luminaire according to the invention with a light source (preferably LED or LED module), wherein the luminous means preferably has a main radiation direction, which particularly preferably extends along a light axis or optical axis. This very particularly preferably corresponds to that axis which connects the light emission area with the optical element.
    According to a fourth aspect, the invention further relates to an optical element, in particular a lens, for a luminaire according to the invention wherein the optical element integrally formed spring elements, to provide the optical element in the luminaire by the restoring force of the spring element positionally positioned. The spring element may in this case have integrally formed spring arms, which extend away from an outer edge region of the optical element.
    Some embodiments of the invention are explained below with reference to the accompanying drawings. Like reference numerals are used for the same features. FIG. 1 shows a sectional view of a luminaire known from the prior art, FIG. 2 shows a sectional view of the luminaire according to the invention in accordance with a first embodiment

    Embodiment.
    Figures 2 and 11 show exemplary lamps 10 according to preferred embodiments of the invention. The lamp 10 has an optical element 1. This can be any kind of optics; especially any kind of lenses. The luminaire further has a light emitting area 2 for receiving a luminous means 21 (for example LED or LED module) which interacts optically with the optical element 1. The combination of luminaire 10 and luminous means 21 is also referred to as a luminaire system 100 in the context of the invention. Furthermore, the luminaire 10 has a spring element 4 which exerts a restoring force upon manipulation of the optical element 1 and / or its positional positioning on / in a positioning element of the luminaire 10. The optical element 1 is formed integrally with the spring element 4.
    Since the spring element 4, which may be any or arbitrarily designed elastic element, is formed integrally with the optical element 1, the known from the prior art additional spring can be omitted and thus the manufacturing and assembly costs are reduced. Preferably, the spring element 4 is formed integrally with the optical element 1 in the form of spring arms 41. The spring arms 41 can be varied by material thickness and / or geometric configuration, thus e.g. to allow a defined adjustment of the optical elements 1 in a manipulation of the same. The spring arms 41 can thereby extend away from the edge region of the optical element 1 and preferably towards the axis of symmetry of the optical element 1, so that a substantially C-shaped cross section of the optical element 1 integrally formed with the spring element 41 results. Advantageously, the cross-section or the material thickness of the spring arms 41 varies with their extension, so that the spring arms 41, e.g. increase or decrease with increasing distance to the optical element 1 in their cross-section or increase or decrease in their material thickness. Advantageously, the cross section is adapted to the load curve in the spring element 4.
    Further, the lamp 10 and the optical system may have a preferably in series switched second optical element 5, which according to the first optical element 1 has an integrally formed spring element 6. The optical element 5 is preferably held in a position relative to the light emitting area 2, e.g. the optical element 5 with the side facing away from the side having the spring element 6 rests on a projection 70 of a housing part 7 and the spring element 6 of the second optical element 5 interacts with the spring element 4 of the first optical element 1 and thereby against the projection 70 of FIG Housing part 7 is pressed and thus held in position relative to the light emitting area 2. Other receiving areas of the lamp 10 are conceivable. It can also be seen easily that the second optical element 5 is not only formed according to the first optical element 1, but also how this is arranged / oriented and thus the side of the second optical element 5, which faces away from the spring element 6 having side the spring element 4 of the first optical element 1 cooperates - that is in contact or operative connection -, and the spring element 6 rests on the projection 70 of the housing part 7. In this case, the second optical element 5 can change its position relative to the light emission area 2 as a function of the relative change in position of the first optical element 1. Advantageously, it can be provided that the first spring element 4 on the one hand and the second spring element 6 on the other hand differ in their geometric configuration, so that different spring constants of the optical elements 1 and 5 result. In this case, the positional changes of the optical elements 1 and 5 relative to the light emitting area 2 would differ due to the different spring constants, e.g. to achieve a desired visual effect. Moreover, it is also conceivable to arrange more than two optical elements relative to one another or to connect them in series, wherein the optical elements are held in a position relative to the light emitting area 2 and / or can be formed according to the first optical element 1. Preferably, the optical elements may also be integrally formed with each other.
    Preferably, the optical elements 1, 5 are additional lenses and / or light-directing lenses, particularly preferably lenses with a concave and / or convex shape. The material of the optical elements may be an elastic material with optical properties, preferably an optical silicone. The integrally formed spring elements 4 and optical elements 1 can be produced together with the optical element 1 preferably via the primary molding process (for example injection molding process) of optical silicone materials or elastomers.
    The optical element 1, 5 with the integrally formed spring elements 4 itself forms an independent inventive part of this invention.
    The luminaire 10 can also have a positioning element 3, 8 for the defined positioning of the optical element 1, in particular with respect to the luminaire 10 or the light emission region 2. Such a positioning element 3, 8 can, for example, a receptacle in the form of a (circumferential) groove, e.g. be in a housing part 7 of the lamp 10, in which the optical element 1, for example, engages edge side with a flange 80, and / or a vorbezeichneter projection 70 on which the optical element 1 (edge side surface) is applied to be secured against falling out axially. To position the optical element 1 defined, find the spring elements 4 application, which are designed so - for example. So with their free ends, for example. In the receptacle or on another part of the lamp 10 are supported - that they the optical element 1 in the defined position by means of a restoring force of the spring element 4 on the positioning element 3, 8 defines. Thus, a secure fit or a secure position positioning of the optical element 1 relative to the positioning element 3, 8 can be achieved.
    In a preferred embodiment, the positioning element is designed such that it allows a manipulation - ie a movement (sbeeinflussung) - of the optical element 1, in particular with respect to the light emitting area 2. For this purpose, the positioning element is designed as a manipulation element 3 for the relative change in position of the optical element 1 with respect to the light-emitting region 2.
    For this relative position change, the lamp 10, as shown in Figure 2, preferably a manipulation element 3, which is particularly preferably a collar 32. Other embodiments of a manipulation element are conceivable in principle, with some preferred and non-exhaustive examples being described within the scope of the invention. The adjusting ring 32 has a thread, so that the adjusting ring 32 can be screwed into a corresponding thread 33 in the housing part 7. By such a configuration, the rotational movement of the adjusting ring 32 can be translated into a screwing. The adjusting ring 32 can be screwed circumferentially onto the optical element 1, so that preferably the optical region of the optical element 1 is not influenced by the adjusting ring.
    By the rotational movement of the adjusting ring 32 can thus change the position of the optical element 1 relative to the light emitting area 2. If the free end of the spring element 4 is in a fixed position relative to the light emission region 2 or on the second optical element 5 or in another moved or stationary position relative to the light emission region 2, then the spring element 4 applies a restoring force to the optical element 1 as a function of the change in position by the manipulation element 3, preferably by the adjusting ring 32, from. By the restoring force is thus ensured that in a manipulation to the starting position, the optical element 1 can be returned to its original position and position, without e.g. due to soiling, tolerance differences or the like occupy a position other than the original position.
    In the case that the second optical element 5 is provided, then in an embodiment of the second optical element 5 according to the first optical element 1 and the same orientation of the two optical elements 1, 5, the position of the second optical element 5 relative to the light emitting area 2 in dependence the rotational movement of the adjusting ring 32 is changed so that the restoring force of the spring element 6 for the second optical element 5 has the same function as the restoring force of the spring element 4 for the first optical element 1. In the event that the second optical element 5 in a position relative to the light emitting area. 2 is held or preferably the second spring element 6 cooperates with the first spring element 4 of the first optical element 1, the force acts proportional to the Ersatzfederkuststante both spring elements 4 and 6 as restoring force for the optical element 1 on the one hand and as a force that holds the second optical element 5 in position , on the other hand. The relative change in position preferably takes place along an axis connecting the light emission area 2 with the optical element 2; Particularly preferably, the connecting axis corresponds to the main emission direction of the luminous means 21, ie its light axis or optical axis.
    Figures 3, 4, 5 and 6 show a second embodiment of the lamp according to the invention. It is advantageous in this embodiment that the optical system or each or at least part of the optical elements 1 of the luminaire 10 can execute a lateral shift, which is preferably a movement transversely to the axis connecting the light output region 2 to the optical element 1.
    The luminaire 10 may have a carrier 34 which can accommodate at least one optical element 1, preferably a plurality of optical elements 1, particularly preferably in the form of a matrix, raster or cluster arrangement such as an intent cluster arrangement. Moreover, it is also conceivable that the carrier 34 is integrally formed with the plurality of optical elements 1, whereby manufacturing and assembly costs can be further reduced. The carrier 34 may be arranged parallel to a housing part 71 which has the light emitting area 2, wherein preferably each of the optical elements 1 is associated with a lighting means 21.
    The optical elements 1 are preferably connected to the free end of the spring elements 4 to the carrier 34, so that a manipulation of the carrier 34 causes the aforementioned restoring force of the spring elements 4. For this purpose, the optical element 1 is preferably fixed with its / its light emitting region 2 facing side / end of the optical element 1 substantially pointwise relative to the light emitting area 2. This selective fixation of the optical element 1 serves as an articulated fastening of the optical element 1 with respect to the light emitting area 2, around which the optical element 1 is pivotably provided.
    For this purpose, a part of the spring element 4 (for example, another spring arm) fix the associated optical element 1 with its free end articulated relative to the light emitting area 2. Preferably, this part of the integrally formed spring 4 may be provided on the side of the light entry region 2 of the optical element 1, which is associated with the lighting means 21.
    The carrier 34 is preferably transversely to the light emitting region 2 with the optical element 1 connecting axis particularly preferably in a plane parallel to the housing part 71 translationally movable / movable. About a translation element, the rotational movement of the manipulation element 31 in the translational movement of the carrier 34 can be set over. Vorteihafterweise the translation element is an eccentric 311, wherein a first part 3111 of the eccentric 311 is rotatably provided in the housing part 71 and a second part 3112 of the eccentric 311 is rotatable and provided with a deviating from the first part of the Ezenters 311 pivot point in the carrier 34 so that itself upon rotation of the eccentric 311, the carrier 34 can translate. In contrast to the side of the carrier 34 having the eccentric 311, a second eccentric 312 configured according to the eccentric 311 can also be provided. By rotation of the manipulation element 3 or the eccentrics 311 and 312, the carrier 34 and thus the optical elements 1 can be positioned transversely to the axis connecting the light emission region 20 to the optical element 1, which preferably corresponds to the main emission direction of the light source 21, in its position or position . Orientation relative to the light emitting area 2 are changed, for example to achieve a certain optical effect. The restoring force of the spring element 4 or of the spring elements 4 also ensures that the optical element 1 or the plurality of optical elements 1 can be returned to its original position. The resilient suspension of the optical elements 1 in the carrier 34 alone can also already cause the provision of the optical system in a lamp 10, a tolerance compensation of the individual optical elements 1 to the associated light emitting area 2, in particular to the associated light source is provided.
    In the event that the optical element 1, for example. About a free end of one of the spring elements 4 relative to the light emitting area 2, preferably on the housing part 71, is fixed, can by the translational movement of the carrier 34 transversely to the light emitting area 2 with the Optic 1 connecting axis, the optical element 1 tilted - so pivoted about the fixing point - are, for example to achieve a further visual effect. Again, by the restoring force of the spring element 4, which may additionally act counter to the tilt, ensuring that the optical elements 1 can be reset to its original position.
    The carrier 34 can also be moved in a direction other than the axis connecting the light emitting region 2 to the optical element 1. Thus, it can likewise be provided that the carrier 34 can additionally or alternatively be moved along the axis connecting the light output region 2 to the optical element 1. It is thus also conceivable to provide a plurality of carriers 34 with optical elements 1 in series, preferably according to the first embodiment in FIG.
    Figures 7 and 8 show a third embodiment of the lamp 10 according to the invention. At least one or more of the optical elements 1 is / are resiliently received on the carrier 34. The support element 34 preferably has ribs or a frame 341, wherein the optical elements 1 are arranged between the ribs 341 and the optical elements 1 are connected to the ribs 341 by means of the free ends of the spring elements 4. The spring elements 4 are preferably designed such that the restoring force can act in the direction of all conceivable degrees of freedom (ie along and about each spatial axis X, Y, Z, in particular in the direction of the spring arms 4). This is preferred by the geometric configuration of the spring element 4 in the form of a spring, spiral, snake or shaft. In this embodiment, it is also advantageously possible to manipulate the individual optical elements 1, for example, individually in their orientation with respect to the luminous means 21.
    Figures 9 and 10 show a fourth embodiment of the lamp 10 according to the invention, this embodiment differs from the third embodiment in that the spring arms 4 are web-like and the optical elements 1 thus can be tilted in particular and the restoring force of the spring elements 4 against the tilting effect. This embodiment essentially shows a carrier 34 with optical elements 1 according to the second embodiment of Figures 3 to 6, wherein in the latter, however, several optical elements 1 are provided between two ribs 341, which in each case via their spring elements 4 - ie the free ends thereof - coupled together are.
    The carriers 34 of the third and fourth embodiments can also be used in the lamp 10 according to the second embodiment. Also differently configured carrier 34 can be used in a lamp 10. Depending on the design of the lamp 10 and the carrier 34 may be adjusted as desired. For example, it is not limited to a rectangular or square frame shape.
    A further advantage of the present invention is also that by means of the integrally formed spring element 4, a tolerance compensation of the optical elements 1 with respect to the light source 21 is made possible. This is particularly advantageous in the case of a cluster arrangement in which numerous optical elements 1 are provided which, due to the resilient function, are preferably aligned individually with respect to their associated lighting means 21.
    The invention is not limited to the embodiments described above as long as it is encompassed by the subject matter of the following claims. All features described above or features shown in the figures can be combined with each other in any advantageous manner within the scope of the invention. In particular, the invention is not limited to the geometrical design examples of the optical elements, spring elements, carrier, lamp (nge-housing), manipulation element, positioning elements.
