    description
    LONG LED LIGHT WITH OPTICAL ELEMENT
    The invention relates to an elongate LED lamp with an optical element.
    The applicant distributes under the trade name TECTON trunking systems with elongated LED lights. These lights have a profile-like housing and an existing plastic optical element. The optical element is connected to the housing by means of a foam bead in order to achieve protection class IP 50. As a result, the assembly process is relatively expensive and expensive.
    The invention has for its object to provide a corresponding improved LED light; In particular, the LED light should allow easier installation.
    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, wherein by the support member, a side wall and a parallel to the latter further side wall of the lamp are formed. Furthermore, the luminaire comprises an LED light source, which is arranged on the carrier element, and an elongated, parallel to the longitudinal axis extending optical element for optically influencing a, emitted from the LED light source light, wherein the optical element between the side wall on the one hand and the another side wall is arranged on the other hand. The side wall is elastically arranged against the pressing of the optical element.
    Characterized in that the side wall elastically presses against the optical element, the transition region between the side wall and the optical element can be particularly easily dense, for example, make dustproof; in particular, it is not necessary to apply a foam bead. Thus, the installation of the lamp is facilitated. Preferably, the optical element has a sidewall region extending parallel to the longitudinal axis over a length, through which a planar outer surface is formed, the sidewall of the carrier element being disposed adjacent to the outer surface of the sidewall region over its entire length. In this way, advantageously, a suitable tightness can be achieved over the entire length of the side wall region.
    Preferably, the side wall of the support member has two legs, which form a V-shape viewed in a cross section normal to the longitudinal axis, wherein one of the two legs is arranged pressingly against the optical element. In this way, manufacturing technology can advantageously achieve an elastic property of the side wall of the carrier element that is suitable for the abovementioned pressing arrangement.
    Preferably, the optical element is held by means of a latching connection to the carrier element. As a result, the optical element can be particularly easily connected to the carrier element for mounting the lamp.
    Preferably, the optical element is also arranged held via a screw on the support element. This allows a particularly secure hold of the optical element on the carrier element.
    Preferably, the latching connection comprises at least one, formed on the side wall portion of the optical element latching element. In this way, the latching connection can be particularly close and thus effectively formed at the point at which the correspondingly tight transitional region between the optical element and the carrier element is located.
    Preferably, the latching connection is formed by the at least one latching element on the one hand and one of the two legs of the side wall of the carrier element on the other. In this way, the locking connection can be particularly simple and yet effective.
    Preferably, the lamp further comprises a further elongate, extending parallel to the longitudinal axis optical element for influencing the optical light emitted from the LED light source, wherein the further optical element is arranged overlapping in the direction of the longitudinal axis with the first-mentioned optical element. As a result, the transition region between the two optical elements can be designed to be particularly dense in a suitable manner. In terms of manufacturing technology, the optical element and the further optical element are preferably shaped in such a way that they-viewed in a section parallel to the longitudinal axis-have intermeshing, in particular interlocking, end regions.
    Preferably, the lamp is designed such that the optical element and the further optical element are arranged parallel to the longitudinal axis with play. This makes it particularly suitable in the case of temperature fluctuations absorb changes in length of the two optical elements.
    Preferably, the lamp further comprises a front part, which is connected to a longitudinal end region of the support member with the latter, wherein the optical element is arranged adjacent to the end part. In this way, a corresponding density can be achieved particularly suitably at the respective front end region of the optical element.
    Preferably, the lamp further comprises a holding element for supporting the lamp, in particular on a mounting rail, wherein the support element is designed such that viewed in a section normal to the longitudinal axis through the support member, a first compartment and a second compartment are formed which are completely separated from each other by a separation region of the carrier element and wherein in the first compartment the LED light source is arranged and in the second compartment the holding element. In this way, a suitable tightness between the two compartments can be achieved; thus greater freedom is given with respect to the design of the retaining element. In addition, it can be achieved in this way that no light from the first compartment enters the second compartment and leaves the lamp from there, which is generally undesirable.
    In terms of manufacturing technology, the carrier element consists of a bent component, in particular of a bent sheet metal part, wherein the separating region is formed by at least one loop-like region of the carrier element.
    The invention will be explained in more detail below with reference to an embodiment and with reference to the drawings. 1 shows a sketch in the manner of an exploded view of a luminaire according to the invention with an optical element, [0019] FIG. 2 shows a sketch of a cross section through the luminaire, [0020] FIG. 3 shows a partial region of the sketch Fig. 2 is a side wall of the Trägerele element and a side wall portion of the optical element, Fig. 4 is a sketch of a partial longitudinal section through the lamp at a transition region between the optical element and another optical element, Fig. 5 a sketch of a longitudinal section through an end portion of the lamp and Fig. 6 is a perspective sketch of a holding element of the lamp.
    Fig. 1 shows a perspective sketch of an embodiment of a lamp according to the application. The lamp comprises a profile-like support element 1, which extends ent long a longitudinal axis L. In terms of manufacturing technology, the carrier element 1 can consist of a bent component, for example of a bent sheet-metal part. Preferably, the support element 1 is generally elongate, so that its largest extension runs parallel to the longitudinal axis L.
    By the support member 1, a side wall 11 and a parallel to the latter further side wall 12 of the lamp is formed.
    Further, the lamp includes an LED light source 2, which is arranged on the carrier element 1, and an elongated, extending parallel to the longitudinal axis L optical element 3 for optically influencing a light emitted from the LED light source 2, wherein the optical element 3 between the side wall 11 on the one hand and the further side wall 12 on the other hand is arranged.
    In Fig. 2 is a cross section through the light normal to the longitudinal axis L sketched. Fig. 3 shows a portion of Fig. 2 in more detail. As in the case of the example shown here, the carrier element 1 may in particular have a U-shaped region in a first approximation, wherein the two side walls 11, 12 form the U-legs of this area and a connecting leg 17 connecting the two U-legs by a further portion of the support element 1 is formed.
    In this description, it is assumed that the lamp relative to the vertical is oriented so that the connecting leg 17 is aligned horizontally and the two U-legs or the two side walls 11,12 of the connecting leg 17 downwards extend. In general, however, a different orientation of the luminaire may be provided.
    By the two free, in this case lower end portions of the two side walls 11, 12, a light exit region of the lamp is preferably formed, through which the light emitted by the LED light source 2 at least partially leaves the luminaire. The optical element 3 is arranged here in this light exit area. In particular, can be formed by a downwardly facing surface of the optical element 3, a light exit surface 39 of the lamp.
    The optical element 3 may, as in the example shown here, be a lenticular element. The optical element 3 is preferably made of a solid material, such as plastic; For example, the optical element 3 may be an injection-molded part. In particular, the optical element 3 is preferably designed so that it consists of only one piece.
    The LED light source 2 can advantageously, as shown, be arranged on a downwardly facing surface region of the connecting leg 17.
    The LED light source 2 advantageously has a printed circuit board 21, as well as a plurality of LEDs 22 arranged on a downward-pointing surface region of the printed circuit board 21, which are preferably arranged along a straight line parallel to the longitudinal axis L. As can be seen by way of example from FIG. 1, the optical element 3 preferably has a plurality of lens regions 37, which extend in particular along a line parallel to the longitudinal axis L. In this case, the design is in particular such that each of the LEDs 22 is associated with exactly one of the lens regions 37.
    In the example shown is formed by the U-shaped portion with the two side walls 11,12 on the one hand and the optical element 3 on the other hand, an interior 15 of the lamp, wherein the LED light source 2 is disposed in this interior space 15.
    The lamp is designed such that the side wall 11 of the support member 1 is arranged elastically pressing against the optical element 3. In this way, manufacturing technology can advantageously achieve that the interior 15 is protected against the penetration of dust, flies and the like. In particular, this allows the luminaire to be suitably designed so that it fulfills the IP 50 degree of protection.
    As sketched by way of example in FIG. 1, the optical element 3 preferably has a side wall region 31 extending over a length X, parallel to the longitudinal axis L, through which a planar outer surface 311, designated in FIG. 2, is formed. wherein the side wall 11 of the support member 1 is disposed across the entire length X abutting the outer surface 311 of the side wall portion 31.
    Specifically, the optical element 3 may be shaped to have a laterally extending wing-like portion 32 in a cross-section normal to the longitudinal axis L, the side wall portion 31 extending upward from the wing-like portion 32 , In the example shown, part of the light exit surface 39 is formed by a lower area of the wing-like area 32.
    The elastic property of the side wall 11 of the support member 1 can be particularly suitably achieved when the side wall 11 has two legs 111, 112 which form a V-shape viewed in a cross section normal to the longitudinal axis L, wherein one of the two legs 111, 112 oppressively against the optical element 3 is arranged. Viewed in the cross section, an "inner" leg 112 is formed in this way with respect to a center axis M of the luminaire by one of the two legs 111, 112 and an "outer" leg 111 by the other. In the example shown, the sidewall region 11 presses with it an upper end portion of the inner leg 112 against the optical element. In this way, with a simple achievement of the desired elasticity allows a particularly suitable use of space.
    Preferably, the optical element 3 is held by means of a latching connection to the support element 1. As a result, the optical element 3 can be particularly easily connected to the carrier element 1 during assembly of the luminaire.
    In addition, the optical element 3 may be arranged held on the carrier element 1 via a screw connection. In this way, a particularly reliable mounting of the optical element 3 on the carrier element 2 can be achieved. As indicated in FIGS. 1 and 3, the optical element 3 may advantageously have at least one screw opening 36 through which at least one screw 7 is guided.
    To form the latching connection, a latching element 33 is preferably formed on the side wall portion 31 of the optical element 3, which is formed in particular with respect to the central axis M facing away from the side wall portion 31 to the outside. The latching element 33 is designed to be particularly space-saving at an upper end region of the side wall region 31. As in the example shown, the latching connection is formed by the at least one latching element 33 on the one hand and one of the two legs 111, 112 of the side wall 11 of the carrier element 1, here the inner leg 112 on the other. In particular, the at least one latching element 33 may be a latching nose, which encompasses an upper end area of the inner leg 112 in a latching manner.
    As can be seen by way of example from FIG. 2, the connection between the optical element 3 and the further side wall 12 of the carrier element 1 is preferably designed analogously to the described connection between the optical element 3 and the first-mentioned side wall 11 of the carrier element 1. In particular, the optical element 3 and the carrier element 1 can be designed symmetrically with respect to the center axis M of the lamp. Accordingly, the optical element 3 can in particular have a corresponding further side wall region 31 'with at least one further latching element 33', which is designed analogously to the first-mentioned sidewall region 31 with the first-mentioned at least one latching element 33; the further side wall 12 of the carrier element 1 can have corresponding legs 111 ', 112', which are designed analogously to the first-mentioned legs 111, 112, so that thus a further inner leg 112 'and a further outer leg 111' are formed are.
    In the example shown, the optical element 3 also has a corresponding further wing-like region 32 ', from which the further side wall region 31' extends upwards. The light-emitting surface 39 is formed by the first-mentioned wing-like region 32 and the further wing-like region 32 '.
    As is apparent from Fig. 1, it can be provided that on the side wall portion 31 and analogously to the further side wall portion 31 'each have a plurality of locking elements 33 and 33' along the longitudinal axis L are formed. A suitable tightness can be achieved in that the upper end portion of the inner leg 112 is elastically disposed against the flat outer surface 311 of the side wall portion 31, over the entire length λ of the side wall portion 31, so that a correspondingly dense, quasi-continuous Investment line or connecting line is formed. Preferably, the design on the opposite with respect to the median plane M side as mentioned analog, in particular identical.
    Preferably, the side wall portion 31 extends over the entire length of the optical element 3. In other words, the length of the optical element 3 is equal to the length λ of the side wall portion 31. In this way, the described tightness can be advantageous over the entire Achieve length of the optical element 3.
    Fig. 4 shows a partial longitudinal section through the lamp. As can be seen from this section, the luminaire can also have a further optical element 4 for optically influencing the light emitted by the LED light source 2, which, like the first-mentioned optical element 3, is elongate and extends parallel to the longitudinal axis L. Since a corresponding optical element can be designed in terms of manufacturing technology comparatively simply up to a certain length, the further optical element 4 makes it possible in particular for the luminaire as a whole to have a particularly great length.
    The further optical element 4 is arranged overlapping in the direction of the longitudinal axis L with the first-mentioned optical element 3. In this way, a suitable dustproof connection can advantageously be formed in this area as well. In addition, it can be achieved so that the transition region between the optical element and the further optical element when viewing the lamp in the operating state appears to be particularly conspicuous.
    Preferably, the optical element 3 and the further optical element 4 are shaped such that they - in a section parallel to the longitudinal axis L considered - interlocking, in particular interlocking intermeshing end portions 39, 49 have. In this way, as it were, a "male" end region 39 can be formed on the first-mentioned optical element 3, and on the other optical element 4 a "female" end region 49 correspondingly shaped for this purpose can be formed.
    Preferably, the design is such that the optical element 3 and the further optical element 4 are arranged parallel to the longitudinal axis L with clearance. In this way it is possible that the two optical elements 3, 4 can expand in the event of a temperature fluctuation without undesirable stresses occurring and can also contract again without the overlap dissolves. 4, a state is shown in which the overlap of the two optical elements 3, 4 is almost dissolved. In an operational state, however, it is provided that the overlap is more pronounced, so that the desired tightness is effected. A mere end-side joining of the two optical elements 3, 4 would not ensure appropriate appropriate tightness.
    Fig. 5 shows a sketch of a longitudinal section through a preferably further provided front part 5 of the lamp, which is connected at a longitudinal end region of the support member 1 with the latter. Preferably, the design is such that the optical element 3 is arranged adjacent to the front part 5. This makes it comparatively easy to form the desired tightness.
    In particular, the front part 5 for this purpose have a downwardly facing wall portion 51, which is arranged in abutment against the optical element 3. In the example shown, the optical element 3 for this purpose has an end-face end region with an upwardly pointing surface region, which the downwardly facing wall region 51 of the front part 5 makes correspondingly tight contact. In this way, the desired tightness can be achieved, whereas here, too, with a mere butt-end joining such a tightness would not be achieved.
    In this way, moreover, the front part 5 is particularly noticeable when looking outside the lamp. This makes it possible, in particular, to achieve a particularly homogeneous light output range.
    The luminaire can be provided to be mounted on a luminous carrier element, for example a mounting rail (not shown in the figures). In particular, the luminaire may be a continuous line luminaire.
    For this purpose, the lamp may have a perspective and exemplary in Fig. 6 sketched holding element 6, for example in the form of a rotary knob. The support element 1 is designed such that - as shown in Fig. 2 - viewed in a section normal to the longitudinal axis L viewed through the support member 1, a first compartment, corresponding to the above-mentioned interior 15 and a second compartment 16 are formed by a separation region of the support element 1, which is formed in particular by the connecting leg 17 of the U-shaped region, are completely separated from each other. In the first compartment 15, the LED light source 2 is arranged. In the second compartment 16, the holding element 6 is arranged. Due to the separation between these two compartments 15, 16 can be achieved that dust or the like from the second compartment 16 can not get into the first compartment 15. This is advantageous with respect to the design possibilities of the second compartment 16; in particular it can be provided that the second compartment 16 has a hole 161, for example in the form of a punched-out, which can be penetrated by the holding element 6; This makes it possible to form a suitable operating option for the retaining element 6. For example, the holding element 6 in the form of a rotary knob having an actuating arm which is arranged leading through the hole 161, so that an operation from the outside is well possible, especially if the lamp is mounted on the light-emitting element, so for example the mounting rail.
    In addition, can be suitably achieve by the separation of the two compartments 15, 16 that no light of the LED light source 2 from the first compartment 15 enters the second compartment 16 and out of this - undesirably - passes to the outside.
    In order to form the separation region 17, provision can be made in particular for the carrier element 1 to form at least one loop-like region 18.
    The lamp according to the application is characterized by a particularly cost-effective and process-safe production by a suitable tightness, in particular dustproofness; Ingress of dust, but also small flies u. s. w. in an interior of the lamp can be suitably prevented. For example, the luminaire is particularly suitable for use in a grocery store or the like.
