    ARRANGEMENT FOR STORING AND PROTECTING AN ELECTRIC GUIDING PCB, IN PARTICULAR AN LED BOARD
    The present invention relates to an arrangement which is provided for storing and for protecting a current-carrying printed circuit board, wherein it is in the circuit board esp. Umeine LED board, which is provided for a high-voltage operation.
    If LEDs are used in luminaires, that is to say for illumination purposes, it should be noted that these LEDs have relatively small dimensions in comparison to conventional light sources such as fluorescent lamps or the like. LEDs are often referred to as punctiform light sources, which accordingly are not optimally suited for uniform light output over a larger area. Therefore, to realize a surface light source, it is necessary to disperse a plurality of LEDs, for example, to be arrayed on a circuit board, and then disposed at a certain distance from the board, a light emitting element which is so light scattering that the individual LEDs are no longer recognizable as individual points of light. Such lights are meanwhile a variety of form in use.
    Basically, depending on Verschaltungsart the LEDs on the corresponding board two ways to operate the LEDs. An operation is known in the so-called small protective voltage, in which therefore only a low voltage is applied to the LEDs themselves and to the feeding lines or printed conductors, which is harmless in case of accidental mixing. In this case, however, the use of special operating equipment is required, which are relatively expensive. Preference therefore so-called hochvolt¬ operated LED boards are used, in which concern the corresponding lines Spannun¬gen, which may be dangerous for humans. Corresponding protection standards therefore stipulate that safety measures must be taken to ensure adequate protection against electric shock. Although this in turn leads to additional measures, however, since high-voltage-operated LED boards can generally be operated more efficiently and are less expensive, this nevertheless represents the preferred variant for LED operation. It should also be taken into consideration that, as a rule, even with operation with protective extra-low voltage a certain shielding of the LEDs from external influences, in particular from accidental contact is required to avoid in particular so-called ESD damage.
    To realize a corresponding contact protection different variants are known from the prior art. For example, solutions are known in which a glass-clear plastic disc is placed inside the lamp in front of the LED board. However, a component of this type is expensive and may possibly impair the light output and thus lead to a reduction of the efficiency. Furthermore, a Verkaps¬lung the LED board is known from the prior art. In this case, the board is inserted into a housing bolted to the translucent cover, forming a so-called light engine. This in turn is snapped into the actual box-shaped lamp housing, so that a double-walled housing construction is formed, by which a accidental touching the LED board is excluded. In order to increase the efficiency, a highly reflective film is placed directly on the LED board in this case, which in turn reflects back reflected light within the light engine and directs it in the direction of the light exit surface of the luminaire. This second variant is also relatively expensive in terms of its construction and requires a relatively deep configuration of the luminaire housing.
    In addition to the disadvantages already described, these known from the prior art solutions also lead to a not inconsiderable additional effort when mounting the light. Because, however, due to the appropriate standards not on a suitable
    Protection of the LED boards can be waived, is increasingly looking for ways to ensure the protection of the LED boards easier.
    The present invention is therefore based on the object to offer a novel possibility, which makes it possible to achieve the prescribed protection of live circuit boards, esp. Of LED boards in a simple and fast way.
    The object is achieved by an arrangement for storing and protecting a current-carrying printed circuit board, esp. An LED board, with the features of claim 1.Vorteilhafte further developments of the invention are the subject of the dependent claims.
    The solution according to the invention is characterized by its simple structure, which allows cost-effective production of the corresponding components involved. Due to the small number of components used, the assembly is further simplified, since no longer need to be mounted by means of special measures additional protection element within a luminaire. Instead, the arrangement according to the invention can be preassembled with the corresponding LED board in a simple manner as a structural unit and then arranged in the luminaire. Nevertheless, it is ensured that the pertinent standards with regard to the protection against electric shocks and the like are complied with.
    The inventive arrangement initially consists essentially of two Elemen¬ten which protect the LED board from both sides. A first element is a plate-shaped carrier element, on which the circuit board is to be arranged. On the opposite side of the carrier element of the circuit board, a plate-shaped protective element according to the invention is further provided, which is connected to the carrier element, so that hereby a corresponding sandwich arrangement is formed, in which the LED board is reliably protected protected between Trä¬gerelement and protective element. According to the invention, it is provided here that the carrier element has support elements for supporting the protective element as well as securing elements. These securing elements are designed in such a way that the protective element has to be displaced from the carrier element in a certain pre-defined direction relative to the carrier element in order to be removed. That is, in the final mounting situation, the protective member is fixed to the support member such that it can only be moved in one direction to be released from the support member. However, in order to prevent this, the arrangement according to the invention additionally comprises a releasably secured to the carrier element locking element which blocks in the assembled state, a sliding of the protective element in the disassembly position.
    According to the present invention, therefore, an arrangement for storing and for protecting a current-carrying printed circuit board, esp. An LED board is proposed, which comprises a plate-shaped support member for the circuit board and a plate-shaped support member to be arranged opposite protective element, wherein the protective element is secured to the support member. According to the invention, the carrier element has contact elements for supporting the protective element and securing elements which are designed such that the protective element first has to be displaced in a first direction relative to the carrier element for removal from the carrier element, the arrangement further comprising a locking element releasably secured to the carrier element, which immontierten state blocks a displacement of the protective element.
    Preferably, the securing elements are formed by hooks which form Ausnehmun¬gen, in which engages the protective element in the mounting position. The hooks hereby are all erected in the same direction, so that the orientation of the hooks defines the direction in which the protective element would have to be displaced for release from the carrier element. The above-mentioned locking element then only has to be arranged and designed such that it prevents a displacement of the protective element in this direction.
    Preferably, at least some of the hooks are arranged on the support elements, with the support elements and / or the safety elements particularly preferably being formed integrally with the support element. This may in particular be the case when the support element is formed by a sheet metal part, in which case the support elements and / or the securing elements are formed by tabs punched out and bent out of the sheet metal part. In this case, the arrangement according to the invention for the storage and protection of the LED board actually only consists of three units, namely the carrier element with the support and securing elements, the protective element and the Verriegelungsele¬ment. All three parts can be produced in a simple and cost-effective manner.
    The locking element itself is preferably formed by an angled, esp. A Z-shaped holding part. This can be attached, for example, by means of a screw on the Trä¬gerelement. It can esp. Provided that the screw comprises two screws, so that a release of the protective element of the support element after releasing the two screws, so after performing two mutually inde pendent work steps, each requiring the use of a tool is possible. Hier¬durch the corresponding standards that are intended to prevent accidental contact with the LED board, clearly met.
    The protective element itself is preferably formed by a transparent plastic plate. This can either be closed continuously or, if appropriate, have corresponding light passage openings in the region of the LEDs. Due to the corresponding distance between the protective element and the LED board, with a corresponding choice of the dimensions of the light passage openings, it can again be ensured that the LEDs are not accidentally touched. In this case, the protective element would not necessarily have to be designed to be transparent, but could alternatively also form a reflective element with individual openings for the LEDs.
    Finally, therefore, a solution for arranging and protecting LED boards in lights is provided by the solution according to the invention, which is characterized by their simple structure and fast assembly, despite all the appropriate safety regulations are reliably maintained can.
    The invention will be explained in more detail with reference to the accompanying drawings. FIG. 1 shows a perspective view of a carrier element of the invention
    Arrangement; Figure 2 is a side view of the carrier element of Figure 1; Figure 3 shows the embodiment of a protective element of the arrangement according to the invention; FIG. 4 shows the protective element arranged on the carrier element and secured; Figure 5 is an enlarged view of the locking element; FIG. 6 shows the protective element connected to the carrier element in a lateral view, and [0023] FIG. 7 shows an enlarged illustration of a partial region of FIG. 6.
    A first essential element of the arrangement according to the invention is the already mentioned support element, which is shown in more detail in Figures 1 and 2. It consists of a plate-shaped sheet metal part 11, which is specially deformed at certain points in the manner described in more detail below. With regard to its external dimensions, the carrier element 10 corresponds approximately to the circuit board to be protected and to be accommodated. In the present case, therefore, a rather square shape is provided, which is made sloping in the corner regions, which could, for example, represent a useful configuration when using an LED board provided as a light source for a luminaire with a circular housing. However, the arrangement according to the invention can be applied to any forms of LED boards and is not limited to the illustrated configuration.
    The carrier element 10 initially serves as a central holding element for the subsequent assembly, which is formed by the carrier element, the LED board and the protective element. It is to give this arrangement a certain stability and at the same time constitute a protection for the back of the LED board. Accordingly, preferably, the carrier element 10 consists of a sheet-metal part which has been correspondingly punched out and deformed. It also has elements for attachment, for example, to the Leuchtenwan¬ne a lamp housing, these elements in the present case by four Bohrun¬gen 12, by means of which a Schraubbefestigung can be made on the housing, are realized. However, these holes 12 could also be used to screw the LED board to be mounted on the support member 10. Smaller and distributed over the entire surface of the support member 10 arranged punch-outs 13 also provide a Aufla¬ge for - not shown in the figures - LED board.
    The support member 10 is to be connected at the same time with the beschrie¬benen further described protective element, in such a way that between the two elements the LED board is added. That is, the protective element should be arranged at a certain distance from the surface of the sheet metal part 11 and secured there, which is made possible by means of the measures described in more detail below.
    These measures consist esp. In that first on the sheet metal part 11 of the support member 10 a plurality of support elements 15 are provided which are in turn distributed over the surface of the support member 10 away formed to support the protection element distributed as large as possible. It is thus prevented that the generally consisting of plastic protective element, which thus has a certain flexibility, can bend because of lack of loca¬ler support and rest on the LED board.
    In Figures 1 and 2, these support elements are verse¬hen with the reference numeral 15. These are tabs punched out of the sheet metal part 11 and bent out substantially perpendicular to the plane of the sheet metal part 11, with a total of 13 support elements being provided in the exemplary embodiment shown. As can be seen from the illustration of FIG. 1, these may well be oriented differently from each other and also be of different lengths. However, in accordance with the representation of FIG. 2, they generally have an identical height h, by which the distance of the protective element from the upper side of the sheet metal part 11 is determined. The protective element placed on this support elements 15 is then arranged over the entire surface parallel to the support element 10 at the predetermined distance h.
    On some support elements 15 also special security elements 16 are formed in the form of hooks. In the present case, eight of the support elements 15 on a corresponding hook 16, these hooks 16 in principle wei¬sen in the same direction. By the orientation of these hooks 16 a certain direction is defined, in which - as will be described in more detail below - the protective element against the Trägerele¬ment 10 must be moved to this from the assembled state to solve be arranged front and at the rear end of a Aufla¬geelement 15 forming tab. As already mentioned, it is not absolutely necessary that each support element 15 has a hook 16. There should be only a sufficient number of hooks 16 distributed over the entire surface of the support member 10 away present. The hooks 16 are slightly higher than the support surface or support edge of the support elements 15, but they form a recess 17 which extends in the amount of this Auflage¬fläche or support edge.
    The to be arranged on the support member and to be connected thereto Schutzele¬ment 20 is shown in plan view in Figure 3. In the present case, this is a plate-shaped element of transparent plastic, which corresponds approximately to the dimensions of the carrier element 10 with regard to its external dimensions. However, these dimensions need not agree 100%, but instead the shape of the protective element 20 will usually be chosen to be as large as possible over the entire surface of the
    Luminaire housing extends across. In other words, in the opened state of the luminaire from its light exit side, the protective element 20 can not be grasped and the LED board can be touched.
    The protective element 20 should therefore be connected in the simplest possible way to the carrier element 10, for which purpose on the carrier element 10, the previously described Auflageelemente15 and hooks 16 are provided. The protective element 20 has distributed over the plate 21hinweg the positions of the hooks 16 corresponding recesses 22. In other words, in the present case, a total of eight recesses 22 are provided in the transparent protective element 20, whose positions or their distribution correspond to the arrangement of the hooks 16 on the carrier element 10.
    The dimensions of these recesses 22 are chosen such that the Schut¬zelement 20 from the top - substantially perpendicular - can be placed on the support element 10 or its support elements 15 such that the hooks 16 with their web-like Sections can reach through the recesses 22. After the protective element 20 has been placed on the carrier element 10 in this way, then both elements are horizontally slightly displaced relative to one another in such a way that the circumferential areas of the recesses 22 of the protective element 20 into the hooks 16 or the recesses 17 of the hooks 16 intervention. According to the illustration according to FIG. 4, this means that the protective element 20 will easily move in the direction of the arrow relative to the carrier element 10, so that it is then hooked to the carrier element 10 at the respective positions of the hooks 16.
    In this position of the protective member 20, the locking member 30 shown in Figs. 4 and 5 is attached to the support member 10. It is a Z-shaped bracket whose upper horizontal portion 31 engages over the end region of a recess 23 of the protective element 20. At the same time, the vertical portion 32 abuts against the end surface of the protective member 20. In the mounted state of the Verriegelungsele¬ments 30 thus a movement of the protective element 20 against the direction of the Pfeilvon Figure 4, ie a movement to release the entanglement between the carrier element 10 and protective element 20 is prevented. In this state, the protective element 20 is then secured to the Trä¬gerelement 10 and can not be easily solved by this. Here, the configuration shown in the side view in FIGS. 6 and 7 results, wherein it can be seen that due to the distributed arrangement of the hooks 16 and the recesses 22, the protective element 20 is secured to the carrier element 10 substantially over the entire area. In the intermediate space between the carrier element 10 and Schut¬zelement 20 then the LED board not shown in the figures can be arranged.
    The locking element 30, so the Z-shaped bracket is preferably secured by means of a screw connection having two screws 35 to the support member 10. By this measure, it is ensured that a release of the lock between carrier element 10 and protective element 20 is made possible only after loosening both screws 35. Thus, two work steps to be performed independently of one another with a tool are required in order to release the protective element 20 from the carrier element 10. As a result, the corresponding standards for reliable protection of the LED board can be more reliably filled.
    An advantage of the inventive solution is also that the Verriegelungs¬ element 30 is only intended to prevent movement of the protective element 20 in the direction of Entriegelungsposi¬tion, but not a jamming of the protective element 20 with the Trä¬gerelement 10 is used. That is, preferably, the shape and position of the locking member 30 is selected so as to leave a certain small margin for moving the protective member 20. In this way it is ensured that at least slight different temperature-related expansions or movements between the protective element 20 and the carrier element 10 can occur and not to increased stresses within
    Plastic existing protective element lead, for example. To its damage leading.
    Ultimately, therefore, the protective element can be attached to the carrier element very easily and quickly, and in spite of everything reliably, reliably preventing later unintentional loosening. The solution according to the invention for receiving and protecting the LED board is characterized in particular by its simple structure and the small number of components used. As a result, on the one hand, the production costs as well as on the other hand, the effort during assembly significantly reduced.
    Finally, it should be noted that in the embodiment described above, the arrangement according to the invention, including the LED board, forms a structural unit which can be arranged in a luminaire housing. However, it would also be conceivable that the luminaire housing itself, which is usually formed from a sheet metal part, forms the carrier element of the arrangement according to the invention. In this case, the bottom surface of the luminaire housing is then preferably provided with the support elements and hooks according to the invention. After mounting the LED circuit board in the luminaire housing, the protective element is then fastened to the support element in the manner according to the invention, ie now on the housing bottom.
