    description
    LONG LED LIGHT
    The invention relates to an elongated LED light (LED: light-emitting diode), also referred to herein as "LED bar light".
    The applicant sells under the name TECTON a lighting system with a mounting rail and a corresponding LED bar light, which is intended to be fixed from below to the mounting rail. In the mounting rail electrical conductors run to power the lamp.
    The lamp has an elongated, profile-like support element. By means of a, arranged on the support element, so-called rotary knob, the lamp can be mechanically connected by locking with the support rail; In addition, can be produced by the rotary knob when making the mechanical connection and an electrical contact with the conductor tracks in the mounting rail, so that in this way a power supply of the lamp is guaranteed.
    As compared to a lamp with a fluorescent lamp as a light source with a corresponding LED lamp of the rotary knob from the bottom is not accessible, the LED light is designed such that the rotary knob has a side actuating arm having an opening in the carrier element engages and can be actuated from the outside.
    It has now been found that in principle there is the possibility that over the opening through which the actuating arm of the rotary knob protrudes, a certain unwanted light emission takes place. This is because part of the light emitted by the LEDs can be reflected and thrown back up within a light emitting area and then exit through the opening through which the operating arm protrudes; this is generally undesirable, in particular it is usually perceived as unpleasant.
    In order to prevent a corresponding light emission through the opening of the support element, the use of separate cover elements would be conceivable that cover the opening accordingly. However, this is associated with increased assembly costs; Moreover, there is basically the risk of incorrect installation of the cover elements.
    The invention has for its object to provide a corresponding improved light; In particular, the luminaire should allow easy manufacture and have a reduced probability of light leakage through the opening of the actuating arm.
    This object is achieved according to the invention with the object mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.
    According to the invention, a lamp is provided which has a profile-like support member which extends along a longitudinal axis, an LED light source, and a holding member for mounting the lamp to a, in particular in the form of a support rail formed light carrier. In this case, viewed in a cross section normal to the longitudinal axis through the carrier element, a first compartment and a second compartment are formed, wherein the LED light source is arranged in the first compartment and the holding element in the second compartment.
    The support member is formed from a bent component, such that viewed in the cross section, the first compartment and the second compartment are completely separated from each other by a separation region of the support member.
    Characterized in that the carrier element is formed from a bent component, it can be particularly easy and inexpensive to divide. Nevertheless, the formation of the two compartments makes it possible to ensure that no light from the first compartment, in which the LED light source is located, penetrates into the second compartment and leaves the luminaire in an undesired manner.
    Preferably, a fold is formed by the support member for complete separation of the two compartments. In this way, advantageously, a corresponding passage of light from the first to the second compartment can be prevented with particular reliability. If the fold comprises a 180 ° bend, it can be designed with particularly advantageous use of space.
    Preferably, in the cross-section, the second compartment, at least in a first approximation, a U-shape with a first U-leg, a second U-leg and one, the two U-legs connecting connecting leg, wherein the fold a through the first U-leg defined plane interspersed. In this way, a passage of light from the first compartment into the region of the first U-leg can be particularly suitably prevented, in particular if the fold is formed between the separation area and the first U-leg. This is particularly advantageous if in the first U-leg, a passage opening for an actuating arm or the like of the holding element is formed.
    Preferably, the connecting leg is at least predominantly formed by the separation region. As a result, in particular a small-scale design is possible.
    Preferably, the first U-leg has a recess, in particular a passage opening, wherein the holding element is arranged passing through the recess. In this way it is possible to achieve that the holding element can be operated particularly suitably from an outside area of the luminaire.
    Preferably, viewed in the cross section, the first compartment, at least in a first approximation, a further U-shape with a further first U-leg, another second U-leg and one, the two other U-legs connecting connecting leg, the latter at least predominantly formed by the separation area. As a result, a particularly suitable use of space is made possible in particular for the design of the lamp.
    Preferably, viewed in the cross section of the separation region of the support member is formed by a preferably rectilinear leg, which consists only of a layer of the component. As a result, in particular the carrier element can be made particularly material-saving. In this case, in particular, in a space-saving manner, preferably the LED light source and / or the holding element are arranged supported on the separating region. In this case, the LED light source is preferably arranged on a first side of the separating region and the holding element is arranged on a second side of the separating region lying opposite the first side.
    Preferably, the carrier element consists of a sheet metal part. This is manufacturing technology advantageous.
    The invention will be explained in more detail below with reference to an embodiment and with reference to the drawings. 1 shows a perspective sketch of an exemplary embodiment of a luminaire according to the invention, [0021] FIG. 2 shows a perspective sketch of a support element of the luminaire, [0022] FIG. 3 shows a cross-sectional sketch of the support element, [0023] FIG 4 shows a cross-sectional sketch of the carrier element with an LED light source and an optical element, and [0024] FIG. 5 shows a perspective sketch of a holding element of the luminaire.
    Fig. 1 shows a perspective sketch in the manner of an exploded view of an embodiment of a lamp according to the application. The luminaire comprises a profile-like carrier element 1 which extends along a longitudinal axis L. In particular, the longitudinal axis L here runs parallel to the axis defined by the profile shape of the carrier element 1. Furthermore, the lamp comprises an LED light source 2. The LED light source 2 is used to generate a light that is emitted by the lamp.
    As indicated in Fig. 5, the lamp further comprises a holding element 3, for example in the form of a lever, in particular in the form of a rotary knob. The holding element 3 is configured to hold the lamp to a light carrier. The light carrier may, for example, be a mounting rail, in particular a mounting rail of a lighting system. Accordingly, the light carrier may also be elongate, being oriented parallel to the light when the light is arranged on it as intended by the holding element 3. The luminaire can accordingly be a continuous line luminaire.
    In Fig. 3 is a cross section of the support member 1 is sketched normal to the longitudinal axis L. Viewed in this cross section, a first compartment I and a second compartment II are formed by the carrier element 1. 4, a corresponding cross-section is sketched, which further shows the LED light source 2. The LED light source 2 is arranged in the first compartment I. As implicitly evident from FIG. 5, the holding element 3 is arranged in the second compartment II.
    As indicated by way of example in FIG. 4, the luminaire may have a light exit region 5 through which the light generated by the LED light source 2 passes into an outer region of the luminaire. In particular, the light exit region 5 can be formed by a light emission opening of the first compartment I. In the example shown, an optical element 4 for influencing the light emitted by the LED light source 2 is arranged between the LED light source 2 and the light exit region 5.
    The carrier element 1 is advantageously formed from a bent component, in particular a bent sheet metal part. The carrier element 1 can therefore be a sheet-metal profile part, with the axis given by the profile shape running parallel to the longitudinal axis L.
    As is apparent from Fig. 3, the component is bent such that viewed in the cross section, the first compartment I and the second compartment II are completely separated from each other by a separation region 11 of the support member 1. In this way, the likelihood that light of the LED light source 2 from the first compartment I penetrates into the second compartment II and subsequently - undesirably - leaves the luminaire can be reduced.
    As can be seen by way of example from FIG. 3, a fold 12 is preferably formed by the carrier element 1 for complete separation of the two compartments I, II. In particular, the fold 12 comprises a 180 ° bend. In the example shown, the fold 12 is formed by a bend with a, parallel to the longitudinal axis L extending bending line. The 180 ° bend is designed such that contact the two, adjacent to the bending line portions of the support member 1 area. This allows a particularly space-saving, suitable separation of the two compartments I, II.
    As further shown in Fig. 3 shows an example, preferably in the cross section, the second compartment II, at least in a first approximation, a U-shape with a first U-leg 14, a second U-leg 15 and one, the two U - legs 14, 15 connecting connecting leg on; In this case, furthermore, the design is preferably such that the fold 12 passes through a plane E defined by the first U leg 14. In the example shown, this plane E runs parallel to the longitudinal axis L. In particular, the first U-leg 14 and the second U-leg 15 can be provided for attaching the luminaire to the luminous carrier for connecting the luminaire.
    Advantageously, the connecting leg of said U-shape of the second compartment II may be at least predominantly formed by the separation region 11 of the support element 1. The fold 12 is preferably formed between the separation region 11 and the first U-leg 14. Further preferably, the design is such that the
    Bend line of the fold 12 runs on a first side of the plane E and a central region of the separation region 11 on the opposite side of the second E level.
    As exemplified in Figures 2 and 5, the first U-leg 14 preferably has a recess 141, in particular a passage opening, wherein the holding element 3, the recess 141 is arranged to pass through. In the example shown, the holding element 3 is formed by a rotary knob, which has an actuating arm, wherein the actuating arm passes through the recess 141, so that a suitable operation from outside the light is possible.
    The design is, for example, such that by an actuation of the actuating arm of the rotary knob between a mounting position and an operating position reciprocates, in particular can be rotated. In the mounting position, the lamp can be attached to the light carrier, so for example the mounting rail. Once the lamp is positioned as intended with respect to the light carrier, the actuating arm can be actuated so that the rotary knob is rotated from the mounting position to the operating position. In the operating position, the lamp is provided as for an operation of the lamp, connected to the light carrier, that is arranged mechanically held on the light carrier.
    Preferably, the holding element 3 is further designed so that it not only serves for the mechanical support of the lamp to the light carrier, but also allows an electrical connection between the light carrier and the lamp, said electrical connection is made when the holding element 3 is in the operating position, but not when the holding member 3 is in the mounting position. Accordingly, the holding element 3 for this purpose has in particular electrical contact areas, which are configured, for example, to contact corresponding electrical conductor tracks which are arranged in the light carrier or the mounting rail for the power supply of the luminaire.
    By the fold 12, the recess 141 can be covered, so to speak, from the side of the first compartment I ago, so that a corresponding passage of light is prevented at this point.
    Further preferably, in the cross section, the first compartment I, at least in a first approximation, another U-shape with another first U-leg 16, another second U-leg 17 and one, the other two U-legs 16, 17 connecting connecting leg, wherein the latter is at least predominantly formed by the separation area 11. The light exit region 5 may in particular be formed between the further first U-leg 16 and the further second U-leg 17.
    In the example shown, the separation area 11 is designed plan, so that by him another level E 'is set, which is preferably oriented perpendicular to the first-mentioned, that is defined by the first U-leg 14 level E perpendicular. For example, it can be provided that the luminaire is aligned for operation in relation to the vertical such that the separating region 11 or the further plane E 'is oriented horizontally.
    Accordingly, here extend the first U-leg 14 and the second U-leg 15 of the U-shape of the second compartment II, starting from the separation area 11 and the further level E 'in a first direction - here as after " Above "- and the other first U-leg 16 and the other second U-leg 17 of the U-shape of the first compartment I in the corresponding opposite direction - also referred to as" down ".
    In the example shown, the design of the carrier element 1 is such that the distance δ1 between the first U-leg 14 and the second U-leg 15 is slightly smaller than the distance 82 to the other first U-leg 16 and the other second U-legs 17. For example, it may be provided that the relationship 3/4 52 <51 <82 applies.
    Preferably, viewed in the cross section, the separating region 11 of the carrier element 1 is formed by a preferably rectilinear leg which consists only of one layer of the component.
    As in the example shown, the case, the LED light source 2 and / or the holding element 3 are preferably mounted on the separation region 11. In particular, the LED light source 2 is arranged on a first side of the separating region 11 -in this case below-and the holding element 3 is arranged on a second side of the separating region 11 lying opposite the first side-here above.
    At the separation area 11, a bearing element 115 may be formed, for example in the form of a curved punched, which serves for pivotal mounting of the retaining element 3.
    The LED light source 2 comprises, for example, a circuit board 21 with LEDs 22 arranged thereon, which is arranged on the separating region 11-for example, directly.
    Preferably, the support member 1 further comprises a further fold 13, which is designed with respect to a, parallel to the longitudinal axis L extending, indicated in Fig. 3, the center plane M of the lamp analogous to the first-mentioned fold 12. Preferably, the second U-leg 15 is further formed corresponding symmetrically to the first U-leg 14; Particularly preferably, the carrier element 1 is configured symmetrically overall with respect to the center plane M.
    In particular, the luminaire enables a cost-effective production; the carrier element 1 can be advantageously produced by bending, for example, roll bending. An unwanted passage of the emitted light from the LED light source 2 in the second compartment II, in which the holding element 3 is arranged, can be practically prevented. In particular, it is not necessary here that subsequently separate elements must be inserted or mounted.
