    LIGHTING BRACKET FOR A LIGHT BAND LAMP
    The present invention relates to a light source carrier for a continuous-line luminaire, and a continuous-line luminaire with such a luminous means carrier.
    A variety of different continuous line lights is known from the prior art. With continuous row luminaires or trunking systems, above all, large rooms (for example supermarkets, factory halls, office rooms, etc.) can be equipped with long light lines adapted to these rooms. Usually, these strip lights have U-shaped strip lights, in which the wiring, the (control) electronics and the illumination means are arranged.
    To simplify the assembly, it is also known to construct the continuous line lights as far as possible with modular units. For example, DE 20 2012 101 765 U1 discloses to arrange a first module in the form of a device carrier and a second module in the form of a luminous means carrier in a U-shaped light band rail. In this case, the illuminant carrier in particular has a luminous-element board with light-emitting diodes arranged thereon or with light-emitting diodes which can be arranged thereon, wherein a heat-sink is usually arranged on the illuminant plate and is thermally connected to the illuminant plate. The thermal connection between the light-emitting diode board and the heat sink is usually provided in such a way that the light-emitting plate is adhesively bonded to the heat sink by means of a thermally highly conductive adhesive. As an alternative to the use of an adhesive, it is also known to screw the light-emitting plate to the heat sink at various locations, so that reliable contacting of the light-emitting plate with the heat sink can be ensured.
    In practice, it has now been shown that the light-emitting plate and the heat sink have a different thermal expansion behavior (in particular due to the use of different materials with different thermal expansion coefficients). Therefore, in practice, it can happen that high voltages occur at the connection of the light emitting diode board to the heat sink, which can lead to cracking in the light emitting diode board or even to the breakage of the light emitting diode board.
    Based on this prior art, the present invention has the object to provide a light source carrier with a light-emitting board and a thermally connected to the light-emitting plate heat sink, in which the risk of cracking due to different thermal expansion of the light-emitting plate and the heat sink prevented or is significantly reduced.
    These and other objects, which will be referred to in the following description or may be recognized by those skilled in the art, are solved by the subject matter of the independent claims.
    An illuminant carrier according to the invention for a continuous-line luminaire comprises: [0008] at least one illuminant board with light-emitting diodes arranged thereon; [0009] at least one heat sink thermally connected to the illuminant board; - Wherein the phosphor plate is rigidly connected to the cooling body at a central region, such that in the central region substantially no relative movement between the light-emitting plate and the heat sink is possible; - Wherein the phosphor board is connected to at least two other areas floating with the heat sink, so that the light-emitting circuit board is arranged outside the central region relative to the heat sink movable on the heat sink.
    In other words, the present invention proposes to connect the phosphor plate only at one area, namely at the central region rigidly connected to the heat sink. A central region in the sense of the present invention is to be understood as meaning a central region of the illuminant circuit board. For example, in a preferably used rectangular light emitting diode board, this is the area at which intersect the lines of symmetry of the light emitting diode board. By the proposed connection of the light-emitting plate to the heat sink, there is thus the possibility that the light-emitting plate and the heat sink can expand differently without the possibility of stress occurring at the connection areas. At the same time a secure thermal connection of the light-emitting plate is ensured with the heat sink.
    Preferably, the phosphor board is rigidly connected in the central region by a rivet, screw and / or clip connection with the heat sink. For example, the illuminant board in the central region at one or more adjacent Gewindesnahmein) of the heat sink are bolted to this.
    Advantageously, the at least two other areas where the light-emitting plate is floatingly connected to the heat sink, provided on two opposite end portions of the light-emitting plate.
    Further, it is preferred that at least one of the floating connections of the light emitting diode board is provided with the heat sink by at least one latching connection by means of a latching element which is provided on a termination connector of a continuous line light.
    Advantageously, the termination connector comprises at least one further latching element in order to lock the termination connector with a correspondingly formed receptacle of the illuminant carrier. The use of such a termination connector is particularly preferred since a particularly stable design of the illuminant carrier can be provided thereby.
    Advantageously, the termination connector further comprises a positioning and / or spacer element, which can be arranged in the frontal region between the illuminant carrier and a light band rail of a continuous-line luminaire. As already stated above, in a modular strip lighting system, the various modules are arranged in a substantially U-shaped light rail, thereby a more accurate positioning of the light source carrier in the U-shaped light rail can be provided by the positioning and / or spacer that a connection of the illuminant carrier can be done with the equipment carrier easier.
    Preferably, at least one of the floating connections of the light-emitting plate is provided with the heat sink by at least one locking connection by means of a locking element which is provided on a connector assembly which is adapted to electrically connect the light source carrier with a device carrier of a continuous line light. In other words, in this preferred embodiment, at least one of the floating connections is provided by a connector assembly that electrically connects the illuminant carrier to the device carrier. Accordingly, in this embodiment, no separate component (for example in the form of a termination connector) is needed.
    Preferably, at least one latching element of the termination connector and / or the connector assembly by at least one correspondingly formed recess of the illuminant carrier can be brought into engagement with the light-emitting circuit, in such a way that the locking element laterally surrounds the heat sink and holds the light-emitting plate in contact with the heat sink , By such a connection is thus the possibility that the light-emitting plate and / or the heat sink can expand differently, in the longitudinal direction of the light-emitting plate by a relative movement with respect to the locking element and in the transverse direction by pushing apart the locking element.
    Advantageously, at least one latching element of the termination connector and / or the connector assembly by at least one correspondingly formed recess of the illuminant carrier can be brought into engagement with the light source board, such that the latching element protrudes through the heat sink and the light-emitting circuit board and the light-emitting plate in contact with the heat sink holds. In this embodiment, the locking element thus does not comprise the heat sink laterally, but is guided through the heat sink and through the light-emitting circuit board and latched thereto, in which case a correspondingly large recess in the heat sink and in the light-emitting circuit board is provided, so that a floating Connection of the lamp board is made possible with the heat sink.
    Furthermore, it is advantageous if the recess is provided by the phosphor plate (30) and / or by the heat sink (31) as a slot.
    Preferably, the illuminant carrier has at least one guide and / or Anlagewandungsabschnitt on or in which the light-emitting plate can be arranged with the heat sink. Such a guide and / or Anlagewandungsabschnitt can be provided, for example, by a circumferential wall portion of the illuminant carrier surrounding the light-emitting plate and the heat sink.
    Advantageously, at least one of the floating connections of the light-emitting plate is provided with the heat sink by at least one screw or rivet connection. The floating connection can be provided by a corresponding loose / loose screw or rivet connection, for example by not firmly screwing the illuminant plate to the heat sink (i.e., the screw is easily loosened so as to permit relative movement of the illuminant board to the heat sink).
    As already stated above, the light-emitting board seen in plan view, a substantially rectangular shape.
    Furthermore, the present invention relates to a strip light with at least one light source carrier described above.
    Hereinafter, a detailed description of the figures will be given. 1 shows a schematic view of a luminous means carrier (without illuminant plate and without heat sink), which is arranged in a U-shaped light band track of a continuous line luminaire; Figure 2 is a schematic view of a terminating connector with which a floating connection of a light emitting panel can be provided with a heat sink; FIG. 3 shows the termination connector from FIG. 2 in a further view; Figure 4 is a schematic view of a lamp carrier with a Leuchtmittelpla tine, which is connected by means of a termination connector shown in Figures 2 and 3 at an end region with a heat sink; 5 shows a cross section through the light source carrier shown in Figure 4.
    Figure 1 shows a schematic cross-sectional view of a U-shaped light rail 1, in which the various modules of a strip light can be arranged, wherein in the U-shaped light rail 1 shown in Figure 1 only one inventive illuminant carrier 5 is arranged (without light source board and without heat sink).
    As can be clearly seen in Figure 1, the lamp carrier 5 is locked by means of several oppositely arranged spring elements 6 with the u-shaped light rail 1 in the area of two lectures 7 of the light rail 1. In this case, the illuminant carrier 5 has a U-shaped cross section which is adapted to the cross section of the light band rail 1 and projects beyond the light band rail 1.
    At the base of the U-shaped cross-section, the illuminant carrier 5 has two recesses 8, through which a latching element of a terminating connector (see FIG
    Connector assembly, which is designed for electrical connection of the illuminant carrier 5 with a device carrier arranged underneath (not shown).
    Adjacent to the recesses 8, the illuminant carrier 5 has in its base two opposite guide and / or Anlagewandungsabschnitte 9, wherein the light-emitting circuit board and its associated heat sink in the region between the guide and / or Anlagewandungsabschnitten 9 can be arranged ( see Figures 4 and 5).
    Further, the illuminant carrier 5 comprises in a region under its base two opposing receptacles / grooves 10, in which a further latching element of the termination connector can be latched to connect the termination connector with the illuminant carrier 5.
    FIG. 2 shows a schematic view of a terminating connector 20 which can be connected to the illuminant carrier 5 shown in FIG.
    The termination connector 20 in this case comprises two opposite latching elements 21, which are arranged corresponding to the recesses 8 of the illuminant carrier 5 on the termination connector 20.
    Furthermore, the terminating connector 20 comprises two further opposing latching elements 22 which are designed to engage in the receptacles 10 provided on the illuminant carrier 5. Furthermore, the terminating connector 20 comprises a positioning and / or spacing element 23 which is to be introduced into the region between the illuminant carrier 5 and the light rail 1, preferably in a form-fitting manner.
    FIG. 3 shows a further schematic view of the terminating connector 20, with identical parts being given the same reference numerals.
    4 shows a schematic view of a luminous means carrier 5, in which a light-emitting plate 30 (with light-emitting diodes 33 arranged thereon) is thermally connected to a heat sink 31, wherein the light-emitting plate 30 is connected to the heat sink 31 in a central region by means of two (adjacent) Screw 32 are rigidly connected and in a front region by means of a termination connector 20 (ie by a lateral engaging behind the locking elements 21 of the heat sink 31 on an upper side of the light-emitting plate 30, so that the light-emitting plate 30 is held or pressed onto the heat sink 31).
    As can be clearly seen in Figure 4, allows the floating connection in the frontal region, that the light-emitting plate 30 and the heat sink 31 move relative to each other, namely in the longitudinal direction of the illuminant carrier 5, characterized in that the light-emitting circuit board 30 and the heat sink Slide 31 under the locking elements 21 of the end connector 20 and in a direction transverse to the longitudinal extent of the illuminant carrier 5 in that the locking elements 21 are pressed apart by the light-emitting plate 30 and by the heat sink 31.
    Despite the possibility of relative movement to each other ensures the locking connection (or even below explained in more detail alternative fastening means of a screw) that the light-emitting plate 30 and the heat sink 31 are held in a thermally effective connection to each other.
    FIG. 5 shows a schematic cross-sectional view of the illuminant carrier 5 shown in FIG. 4 in a region of the latching elements 21. The same parts are in turn provided with the same reference numerals.
    As an alternative to the lateral arrangement of the latching elements 21 shown in the figures, it is possible to guide snap-in elements through the illuminant board 30 and through the heat sink 31, in which case a correspondingly large recess in the illuminant board 30 and in the heat sink 31 is, so that further a floating arrangement, ie a relative movement of the heat sink 31 to the light-emitting plate 30, is made possible.
    Further, there is the possibility of providing a floating connection in the end regions (instead of the illustrated termination connector 20) in that the light-emitting plate 30 is screwed to the heat sink 31, in which case a loose screw is provided, in turn, a relative movement of the To allow heat sink 31 to the lamp board 30 (which is preferably supported by the use of a slot through which screw is passed). The screw connections can also be provided at the same positions as the locking elements 21 shown in the figures, in which case the screw head engages around the heat sink 31 and the light-emitting plate 30 laterally.
    The present invention is not limited to the previously described preferred embodiments as long as it is encompassed by the subject matter of the following claims. In particular, the present invention is not limited to the use of the termination connector 20 shown. Furthermore, different connections can be used in the respective end regions (for example, a floating connection can be provided on one side by means of the termination connector 20, and on the opposite side by means of a loose screw connection).
