    The invention will be explained in more detail below with reference to an exemplary embodiment and with reference to the drawings. 1 shows a perspective sketch in the manner of an exploded view of a luminaire according to the invention, [0022] FIG. 2 shows a perspective sketch of the separated optical element, [0023] FIG. 3 shows a cross section through the carrier element, the LED [0024] FIG. 4 is a side view of the optical element, before connection to the carrier element, [0025] FIG. 5 is a perspective detail sketch around a central region of the optical device
    And Fig. 6 is a perspective detail sketch of an end portion of the optical element.
    Fig. 1 shows a perspective sketch in the manner of an exploded view of an exemplary embodiment of a lamp according to the invention. The luminaire has an elongate carrier element 1. In this case, the support element 1 can be designed profile-like. In particular, the carrier element 1 may be formed as a sheet metal profile part. As a result, the carrier element 1 can be produced particularly inexpensively.
    Furthermore, the lamp has an LED light source 5 for generating a light. The LED light source 5 is arranged on the carrier element 1.
    Furthermore, the lamp has an optical element 3 for influencing the light. The optical element 3 is generally oblong, so that it extends along a longitudinal axis L. Correspondingly, the optical element 3 has two end regions 36, 37 with respect to the longitudinal axis L, as well as a central region 35 located between the two end regions 36, 37. In this case, the optical element 3 is parallel to the longitudinal extension L of the longitudinal axis L Carrier element 1 is arranged.
    In terms of manufacturing technology, the optical element 3 is made of a plastic. For example, it may be designed as a plastic injection molded part.
    In Fig. 2 is a perspective sketch of the separated optical element 2 is shown. 4 shows a side view of the optical element 3 in a state before connection to the carrier element 1.
    The design of the luminaire is such that the optical element 3 is under a bending stress when it is connected as intended with the carrier element 1. Vorzugswei-se is the design here such that the optical element 3 as such, so if it is not yet connected to the support member 1, has a slight Kriimmung, and indeed-as in Fig. 4 indicated - such that the optical element 3 on one side, which in the finished assembled light to the support member 1 has slightly concave.
    For example, it can be provided that this curvature in a first approximation has a radius of curvature which is greater than three times, preferably greater than five times the extension of the optical element 3 along the longitudinal axis L. To assemble the lamp can then the optical element 3 are connected to the support member 1 such that the curvature is at least substantially canceled; In this way it can be achieved that the optical element 3 forms a particularly suitable, dense system on a further component of the luminaire, that is, for example, on the carrier element 1 and / or on the LED light source 5. Thus, a particularly cause reliable positioning of the optical element 3 with respect to the LED light source 5, which is advantageous with respect to the accuracy of the light influencing.
    In the example shown, the design is such that the LED light source 5 has an LED board 2, and LEDs 6, which are arranged on the LED board 2; In this case - the LED board 2 is pressed by the optical element 3 against the support element 1 - in the assembled state of the lamp. The described slightly curved execution of the optical element 3, a corresponding Andriicken is particularly suitable. In particular, the distance between the LEDs 6 and the optical element 3 can thereby be set particularly precisely. Preferably, the LED board 2 is elongate, extending parallel to the carrier element 1.
    As in the example shown, the case preferably further comprises at least one connecting element 4 for supporting the optical element 3 on the carrier element 1, wherein the at least one connecting element 4 with respect to the longitudinal axis L at the central region 35 of the optical Elements 3 is arranged attacking, in particular within the corresponding middle fifth of the optical element 3. The mentioned curvature can be canceled in the course of assembly of the lamp particularly suitable when the optical element 3 is held on the support member 1, that the at least one connecting element 4 exerts a force on the optical element 3 which acts perpendicular to the longitudinal axis L, that is to say in particular as indicated in FIG. 1 by an arrow R, which shows the effective direction of the connecting element 4. Preferably, the connecting element 4 is a screw; In particular, it can advantageously be provided that - as indicated in FIG. 1 - two connecting elements 4 or two screws are provided, which are preferably arranged opposite one another with respect to the longitudinal axis L.
    By using a screw can also achieve that the optical element 3 can not be dismantled without the aid of a tool; This is advantageous with respect to the safety of the luminaire, since the LED board 2 can generally carry high-voltage voltage.
    In the example shown, the optical element 3 has a plurality of lens areas 32, wherein the design is such that in each case one of the LEDs 6 is associated with one of the lens areas 32. The LEDs 6 are preferably arranged along a straight line parallel to the longitudinal axis L, the lens regions 32 also being arranged on a straight line parallel thereto.
    In the example shown, the optical element is designed analogously with respect to the longitudinal axis L on the two opposite sides. In the following, therefore, particular attention is given to the design on one side of the longitudinal axis L. 3, a cross-section through the optical element 3, the carrier element 1 and the LED light source 5 is sketched, at the level of the end region 36 of the optical element 3. As shown, the lens regions 32 are in a section normal to the longitudinal axis L is preferably formed in a middle area of the optical element 3; As is apparent from Fig. 2, while the two connecting elements 4 with respect to the longitudinal axis L and the lens portions 32 on the optical element 3 on two opposite sides.
    In the example shown, the optical element 3 has two screw domes or screw channels 39 for guiding the two connecting elements 4, which are accordingly arranged opposite each other with respect to the lens areas 32. Preferably, further connections which fix the optical element 3 with respect to the carrier element 1 along the longitudinal axis L are not provided; Thus, the risk of cracking of the screw 39 can be kept very small.
    Preferably, the lamp is designed such that the optical element 3 is not fixed at its two end portions 36, 37 in a direction of the longitudinal axis L relative to the Trägerele-element 1 in its position, in particular in both, by the longitudinal axis L. fixed directions. Further preferably, the design is such that the optical element 3 is fixed at its two end portions 36, 37 in a direction transverse to the longitudinal axis L relative to the support member 1 in position, in particular in those two directions which are transverse to the longitudinal axis L and are perpendicular to the direction of action R of the connecting element 4. In this way, it can be achieved that a relative movement between the two end regions 36, 37 of the optical element 3 on the one hand and the carrier element 1 or the LED board 2 on the other hand in a direction parallel to the longitudinal axis L is possible, transversely thereto However not.
    This is advantageous because in the case of a temperature change, for example due to operation, it can happen that the optical element 3 and the carrier element 1 undergo different changes in length, so that in principle there is a risk that this will result in unwanted effects Tensions arise. Due to the fact that the end regions 36, 37 of the optical element 3 are not fixed in a direction parallel to the longitudinal axis L, in particular in both directions defined by the longitudinal axis L, corresponding compensatory movements may possibly take place here, so that such stresses are avoided.
    Preferably, between the support element 1 and the optical element 3 a
    Detent connection formed. This makes it possible to effect the described positional relationship particularly suitable. In the example shown, the optical element 3 for this purpose latching elements 31, which interact to form the latching connection with shoulder surfaces 11 of the support element 1. The latching elements 31 and the shoulder surfaces 11 are configured profile-like, parallel to the longitudinal axis L. In the example shown, the optical element 3 on both sides of the lens elements 32 each have seven locking elements 31, a total of fourteen latching elements 31. The shoulder surfaces 11 are preferably formed by the profile shape of the support member 1, so that on each side of the lens elements 32 each have a school terfläche 11 is formed.
    In the example shown, the LED board 2 with respect to the longitudinal axis L on a central region 25 which is arranged fixed in a direction of the longitudinal axis L against the optical element 3 in its position, in particular in both, by the longitudinal axis L fixed directions. This makes it possible to achieve that a relative movement between the LED board 2 on the one hand and the carrier element 1 or the optical element 3 on the other hand, caused by a temperature change, remains relatively small. In particular, this makes it possible to achieve that the lens regions 32 only move relatively little relative to their respectively associated LEDs 6 along the longitudinal axis, so that the optical effect of the optical element 1 depends very little on the temperature change.
    Manufacturing technology advantageous may be provided for this purpose that the LED board 2 has a recess 29 in its central region 25 and the optical element 1 engaging in this recess 29, in particular formschliissig is arranged engaging. FIG. 5 shows a perspective sketch about the central region 35 of the optical element 3. In the example shown, the optical element 3 has a positioning element 33 for the corresponding positive engagement in the recess 29. For example, the positioning element 33 may be arranged or formed on the screw dome 39.
    In the example shown, the optical element 3 also has a further positioning element 34, which serves for positioning the optical element 3 relative to the carrier element 1. Preferably, the further positioning element 34 is arranged or formed on the screw dome 32.
    Preferably, the LED board 2 is not fixed at its two, formed with respect to the longitudinal axis L end portions 26, 27 in a direction of the longitudinal axis L against the optical element 3 in position, in particular in the two, through the Longitudinal axis L fixed directions. Further preferably, the design is such that the LED board 2 is arranged fixed at its two end regions 26, 27 in a direction transverse to the longitudinal axis L with respect to the optical element 3 in its position. As a result, analogously to the securing of the position of the optical element 3 relative to the carrier element 1, the LED board 2 can be correspondingly suitably arranged in relation to the optical element 3. Correspondingly, the design is in particular such that the LED board 2 at its two end regions 26, 27 is fixed in position relative to the optical element 3 in its two directions which run transversely to the longitudinal axis L and thereby perpendicularly to it the direction of action R of the connecting element 4th
    To achieve this arrangement can - as in the example shown the case and sketched in more detail in Fig. 6 - the optical element 3 at one of its two end portions 36, 37 have an arm portion 38, wherein the LED board 2 in one of its end portions 26, 27 a, designated in Fig. 1, further recess 28 and the arm portion 38 of the optical element 3, in particular with a corresponding projection 382 is arranged engaging in the further recess 28 of the LED board 2. Preferably, the design is analogous to the corresponding other end region. Since, in the example shown, the design with respect to the lens elements 32 is analogous on both opposite sides, a total of four corresponding arm regions 38 and corresponding further recesses 28 are thus formed.
    Thus, a suitable lateral, ie directed transversely to the longitudinal axis L guidance of the LED board 2 can be effected by the arm portions 38, that is, by the leadership, the LED board 2 can not emigrate laterally relative to the optical element 3. In the direction of the longitudinal axis L, however, there is a certain amount of play that allows mutual shifting due to temperature fluctuations.
    The LED board 2 is thus fixed in its central region 25, in particular in its corre sponding middle fifth, relative to the carrier element 1, at its two end regions 26, 27, however, a certain length compensation can take place.
    In the example shown, the arm region 38 also has an abutment region 381, which is designed for a planar abutment against the LED board 2. This makes it possible to achieve that the optical element 1 presses particularly suitably against the LED board 2 and the latter accordingly advantageously holds in position.
    By the described design can be achieved that the optical element 3 - with a suitable optical accuracy of the lamp - can be made comparatively long; For example, the length of the optical element 3 may be more than 30 cm, preferably more than 40 cm.
    For mounting can be provided that in a first step, the LED board 2 is placed on the optical element 3, in such a way that the positioning elements 33 of the optical element 3 in the recesses 29 of the LED board. 2 intervene as planned. In a subsequent, second step, the carrier element 1 is connected to the optical element 3 by means of the latching connection. In a subsequent, third step, the optical element 3 is then firmly connected to the carrier element 1 by means of the at least one connecting element 4 or by means of the two screws; In this case, the slight tendency of the optical element 3 to be canceled and the optical element 3 applies precisely to the LED board 2.
    In terms of manufacturing technology, the aforementioned tendency of the optical element 3 to be achieved in the course of production by means of an injection molding tool can be achieved by a corresponding control of the cooling. For this purpose, the injection molding tool can be designed so that the optical element 3 is initially formed without the Kriimmung, but during the Abkiih-lungsphase a one-sided stronger cooling takes place and thereby the gewiinschte Kriimmung is generated.
    In the luminaire according to the invention, a particularly precise contact of the optical element 3 over its entire length on the LED board 2 or the carrier element 1 can be achieved. Thus, in particular, it can be ensured that a precisely defined distance is maintained between the lens sections 32 and the respective associated LEDs 6. In addition, the carrier element can be designed as a sheet metal profile part and thus relatively inexpensive.
