    description
    LIGHTBAND SYSTEM LUMINAIRE WITH REFLECTOR, LIGHTBAND SYSTEM AND OPTICAL LENS ELEMENT The invention relates to a luminaire for use in a light band system, the luminaire comprising a luminaire housing, an LED light source (LED: light-emitting diode), an optical lens element and a reflector. The invention further relates to a corresponding light band system and a corresponding optical lens element.
    Such a lamp is known from DE 20 2012 100 628 U1. With this lamp, it is provided that the reflector is snapped onto the housing of the lamp from the outside. Therefore, the reflector extends significantly beyond the housing when viewed in the direction of light emission. This usually affects the external appearance of the lamp.
    The invention has for its object to provide a corresponding improved lamp. In particular, the luminaire is intended to offer advantageous properties with regard to the design options for the external appearance, with the reflector being easy to install. In addition, a corresponding light band system and a corresponding optical lens element are to be specified.
    This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are specified in the dependent claims.
    According to the invention, a luminaire for use in a continuous row system is provided which has an elongated luminaire housing which extends along a longitudinal axis, and an LED light source arranged in the luminaire housing for generating a light. Furthermore, the lamp has an optical lens element for influencing the light, and a reflector for further influencing the light. The reflector is arranged directly on the optical lens element.
    As a result, the reflector can be particularly suitably coupled directly to the optical lens element, with a particularly small-scale design being made possible overall. This is also particularly advantageous with regard to the design of the external appearance of the luminaire and also of the light band system.
    Preferably, the reflector is arranged reversibly detachably held on the optical lens element. This makes it particularly easy to disassemble and reassemble. A particularly simple handling is possible if the reflector is arranged held on the optical lens element via a snap-in connection.
    Preferably, the optical lens element is formed to extend along the longitudinal axis, wherein it has a U-shaped recess viewed in a cross section normal to the longitudinal axis and the reflector is arranged engaging in the recess. In this way, a particularly reliable mounting of the reflector on the optical lens element is made possible.
    Preferably, the optical lens element has a lens area for influencing the light, wherein - viewed in cross section - the recess is formed on one side next to the lens area. The reflector is particularly suitable for achieving light emission from the luminaire towards one side, i.e. for asymmetrical light emission.
    Preferably, the optical lens element on an edge region of the recess has a contact surface for contacting the reflector. This enables a particularly precise alignment of the reflector with respect to the optical lens element.
    Preferably, the reflector has a knob that snaps into the recess 1/13
    AT16316U1 2019-07-15 Austrian
    Patent Office is arranged. This is advantageous with regard to a particularly reliable mounting and positioning of the reflector.
    Preferably, the optical lens element is symmetrical with respect to a central plane of the lamp. In this way, it can be achieved in particular that the reflector can be easily arranged on two opposite sides with respect to the longitudinal axis.
    Preferably, the reflector is formed to extend along the longitudinal axis, wherein viewed in a cross section normal to the longitudinal axis, it has a concave reflection surface for directing the light. This enables particularly effective light control.
    Preferably, the design is such that - viewed in cross section - the light through the optical lens element is divided into two separate main parts, one of the two main parts falling on the reflection surface of the reflector and the other main part not on the reflection surface falls. In this way it can be achieved, for example, that the main portion that is not reflected on the reflection surface is used to illuminate a lower region of a wall and the main portion that is reflected on the reflection surface is used to illuminate an upper region of the wall.
    According to a further aspect of the invention, a light band system is provided which has a day rail extending along a longitudinal axis and a lamp according to the invention which is arranged held in the mounting rail.
    Preferably, the support rail in a cross section normal to the longitudinal axis viewed in a first approximation to a U-shape, so that two U-legs are formed, the lamp being arranged within the space that extends between the two US legs , This enables a particularly unobtrusive design.
    Preferably, the reflector is also arranged within the space that extends between the two U-legs. In this way, it can be achieved, in particular, that the appearance is not impaired by a reflector projecting above the mounting rail.
    Preferably, a light exit opening for the light is formed by the free end regions of the two U-legs, the light exit opening being covered by a translucent cover. In particular, the reflector can be arranged behind the cover in a particularly inconspicuous manner. If the cover is cloudy or milky, the risk of unwanted streaking can be reduced.
    According to a further aspect of the invention, an elongated, along a longitudinal axis extending optical lens element is provided for a lamp, which is designed for use in a light band system and has an elongated lamp housing extending along the longitudinal axis and one, in the lamp housing arranged LED light source for generating a light, in particular for a lamp according to the invention. The optical lens element has a lens area for influencing the light. When viewed in a cross section normal to the longitudinal axis, the optical lens element has a U-shaped recess which is designed to hold a reflector.
    The invention is explained below using an exemplary embodiment and with reference to the drawings. Show it:
    Fig. 1, 2, 3, 4 show a cross-sectional sketch of a lamp according to the invention, a cross-sectional sketch of the optical lens element of the lamp, a cross-sectional sketch of the reflector of the lamp , a cross-sectional sketch of a trunking system with a lamp according to the invention and

    AT16316U1 2019-07-15 Austrian
    Figures 5a and 5b two cross-sectional sketches to illustrate the division of light by the optical lens element into two main parts.
    Fig. 1 shows a cross section through a lamp according to the invention. The lamp has an elongated lamp housing 1 which extends along a longitudinal axis. As in the example shown, the luminaire housing 1 is preferably designed as a profile element, the profile axis being directed parallel to the longitudinal axis. Fig. 1 shows a cross section normal to the longitudinal axis or normal to the profile axis.
    Preferably, the lamp housing 1 is viewed in normal cross section in a first approximation U-shaped, so that a first U-leg 17, a second U-leg 18 and one, the two U-legs 17, 18 connecting leg 19 formed are.
    The luminaire is designed for use in a light band system, the light band system preferably comprising - as outlined in FIG. 4 in a corresponding cross section, a support rail 10 extending along the longitudinal axis. The design is such that the lamp is or can be arranged held in the mounting rail 10, for example via a snap connection. In particular, the cross-section of the support rail 10 can also have a U-shape as a first approximation, so that two U-legs 11, 12 are also formed by the support rail, the lamp being or being arranged within the space that is between extends the two U-legs 11, 12 of the mounting rail 10.
    Furthermore, the lamp has an LED light source 2 arranged in the lamp housing 1 for generating a light. In the example shown, the LED light source 2 comprises an LED circuit board 16, on which a plurality of LEDs 15 are arranged, the LEDs 15 preferably being arranged in such a way that they form a row extending parallel to the longitudinal axis. Accordingly, the lamp can be referred to as an LED bar lamp.
    A light outlet opening 13 for the light generated by the LED light source 2 is preferably formed by the free end regions of the two U-legs 11, 12 of the mounting rail 10. Furthermore, the light exit opening 13 is preferably covered by a translucent cover 14.
    The light band system can be provided to be oriented for operation in such a way that the light is emitted by the lamp in the lower half-space, as indicated in Fig. 4 by an arrow R. For example, it can be provided that the mounting rail 10 is fastened to a ceiling, for example directly or via suspension elements, the two U-legs 11, 12 pointing vertically downward. Such an orientation is assumed in this description. In general, however, a different orientation of the carrier element 10 with respect to the vertical can also be provided.
    In the light strip system considered here, the design is such that the mounting rail 10 extends further along the longitudinal axis - that is, it has a greater length than the lamp. Rather, the mounting rail 10 is preferably so long that a plurality of corresponding lights can be arranged in an analogous manner adjacent to one another on the end faces. In this way, a particularly long light band can be created with the continuous row system and several corresponding luminaires.
    Furthermore, the lamp has an optical lens element 3 for influencing the light. In particular, the optical lens element 3 has a lens area 6 for this purpose, the optical lens element 3 being arranged such that the major part of the light generated by the LED light source 2 passes through the lens area 6. The design is preferably such that no further element for optically influencing the light is arranged between the LED light source 2 on the one hand and the lens region 6 on the other hand.
    In particular, as sketched in FIG. 1, the lens region 6 can have an indentation formed by a concave shape on its side facing the LED light source 2 and, for example, have convex and concave sections on the opposite side
    AT16316U1 2019-07-15 Austrian
    Patentamt sen. In this case, the LED light source 2, in particular with its LEDs 15, can be arranged so as to engage in the indentation in terms of lighting technology.
    Preferably, the optical lens element 3 can in particular be arranged directly on the luminaire housing 1, for example on the connecting leg 19 of the luminaire housing 1. A particularly simple mounting option is provided if a latching connection is provided here.
    Furthermore, the lamp has a reflector 4, which is designed to further influence the light. The reflector 4 is arranged directly on the optical lens element 3. In the exemplary embodiment shown, the reflector 4 is designed in such a way that it at least predominantly directs the portion of the light striking it with respect to the direction R to one side, so that asymmetrical light emission is achieved. This can be desirable, for example, if a vertical wall is to be illuminated, which is located on the corresponding side at an angle below the lamp.
    The reflector 4 is reversibly detachably arranged on the optical lens element 3 in the embodiment shown, in particular it is arranged on the optical lens element 3 via a snap connection. In this way it can be achieved that the reflector 4 can be removed from the lamp in a particularly easy-to-use manner and can be reinstalled.
    [0038] The optical lens element 3 is preferably designed to extend along the longitudinal axis. Viewed in cross section normal to the longitudinal axis, it preferably has a U-shaped recess 5, the reflector 4 being arranged to engage in the recess 5. This enables a particularly stable mounting of the reflector 4 on the optical lens element 3. In the example shown, the recess 5 is elongated, with its longitudinal axis extending essentially perpendicular to the main extension of the two U-legs 17, 18 of the lamp housing 1 or horizontally in the orientation considered here. This enables a particularly suitable stable suspension of the reflector 4.
    The recess 5 is - viewed in the normal cross-section - formed on one side next to the lens region 6, with reference to FIG. 1 to the left of the lens region
    6. The desired asymmetrical light control by the reflector 4 can thus be achieved in a particularly suitable manner.
    As shown by way of example, the reflector 4 can have, in particular, a knob 8 for a particularly suitable holder, which is arranged engagingly engaging in the recess 5.
    2, the optical lens element 3 is sketched separately in cross section. It can be seen that a recess 29 corresponding to the knob 8 and shaped in the recess 5 can be provided for a particularly suitable latching connection between the optical lens element 3 and the reflector 4. Fig. 3 shows the reflector 4 separated in a corresponding cross-sectional view.
    Advantageously, the optical lens element 3 can be designed profile-like, for example as an extruded component, the corresponding profile axis extending parallel to the longitudinal axis. The optical lens element 3 can advantageously be made of a plastic such as PC (polycarbonate). The optical lens element 3 can advantageously be designed as an ESD protective part (ESD: electrostatic discharge). It is particularly advantageous here if the optical lens element 3 is connected to the lamp housing 1 in such a way that it cannot be removed from the latter without a special tool.
    [0043] The reflector 4 can at least essentially also be designed in profile-like manner, the corresponding profile axis extending parallel to the longitudinal axis. The reflector 4 can have a plurality of corresponding knobs 8 extending in a row along the longitudinal axis. This is a particularly stable connection between the optical

    Patent Office
    Lens element 3 and the reflector 4 allows.
    For a particularly suitable light control, the reflector 4 preferably has a reflection surface 9 which, viewed in the normal cross section, is concavely curved.
    5a and 5b show two schematic sketches for an embodiment in which the design is such that - viewed in a cross section normal to the longitudinal axis - the light generated by the LED light source 2 through the optical lens element 3 is divided into two separate main parts, a first main part H1 and a second main part H2. For example, a so-called batwing distribution can be formed. The two main parts H1, H2 are designed symmetrically, in particular with respect to the direction R. In FIG. 5a only the first main part H1 is indicated by exemplary light beams, in FIG. 5b the second main part H2 is correspondingly indicated. The first main portion H1 falls on the reflection surface 9, but the second main portion H2 does not. For example, a vertical wall can advantageously be illuminated, which is located on the right below the lamp 1. The first main portion H1 can be used to illuminate an upper wall area and the second main portion H2 to illuminate a lower wall area.
    It is particularly advantageous if the cover 14 is cloudy or milky, because this can reduce or even exclude the risk of unwanted streaking.
    As is the case in the example shown, the reflector 4, viewed in normal cross section, can have an upper horizontal leg 20 which is or can be arranged to engage in the recess 5 of the optical lens element 3 and on which the knobs 8 are integrally formed. Furthermore, the reflector 4 can have a lower horizontal leg 21 which - in the orientation considered here - extends below the upper horizontal leg 20, a curved section 23 being formed between the upper horizontal leg 20 and the lower horizontal leg 21 which the reflection surface 9 is formed. The reflector 4 advantageously also has a contact leg 22 which extends obliquely upwards from the lower horizontal leg 21, specifically from the end region of the lower horizontal leg 21 opposite the curved section 23. The contact leg 22 is designed to be arranged adjacent to the lower free end region of the first U-leg 17 of the lamp housing 1. This enables a particularly precise alignment or positioning of the reflector 4 relative to the lamp housing 1.
    Also for a particularly precise alignment of the reflector 4, the optical lens element 3 can furthermore have a contact surface 7 for contacting the reflector 4 at an edge region of the recess 5.
    Furthermore, the optical lens element 3 is preferably designed symmetrically with respect to an in particular vertical central plane M of the lamp. In the example shown, this center plane M runs through the LEDs 15 of the LED light source 2. In this way it can be achieved that the reflector 4 can either be arranged on one of the two sides of the lens region 6 or can be snapped onto the optical lens element 3.
    The reflector 4 can generally be connected to the optical lens element 3 as provided, regardless of whether the lamp is arranged in the mounting rail 10 or not.
    4, the design is preferably such that the reflector 4 extends only on one side of the central plane M, ie does not reach through the central plane M when connected to the optical lens element 3 as intended is.
    As further sketched as an example in FIG. 4, the reflector 4 is preferably also arranged within the space that is between the two U-legs 11, 12

    Patent Office of the support member 10 extends. The light exit opening 13 for the light formed by the free end regions of the two U-legs 11, 12 is, as mentioned above, preferably covered by a translucent cover 14. As a result of the design described, the reflector 4 is located behind the cover 14, as seen by a viewer of the light band system. Therefore, the design described is advantageous with regard to the design options for the external appearance of the light band system.
