    OPERATING DEVICE FOR A LAMP
    The present invention relates to an operating device for a lighting means and a Verfah¬ren for the production of the operating device. In this case, the operating device has improved properties with respect to electromagnetic interference and can be produced inexpensively by the method according to the invention.
    There are several methods for the production of operating devices for lighting, wherein a housing of the operating device is generally completely cast with a potting compound to dissipate the heat of built-in components on the potting compound.Another reason for the potting of the components is the copy protection, ie Reverse engineering is made considerably more difficult by casting, for example when bituminous asphalt is used as potting compound.
    The preparation is typically carried out so that an upper housing shell of the Gehäu¬ses is tilted to the side or down and then completely filled with potting material.
    A major disadvantage of the complete potting is that a Ausga¬sen the components is not possible or only very limited. As a result, damage can occur during operation that restrict or even damage the functionality of the operating device. Likewise, the potting compound may damage the devices, particularly when performing thermal cycling tests, and adversely affect the EMI performance of the operating device. In addition, full potting requires a large amount of potting material, which increases manufacturing costs.
    In DE 10 2010 027 980 A1 an operating device and a method is described in which the housing is only partially filled with potting material. In this example, the area not potted with encapsulant is filled with a filling material which is intended to compensate for the disadvantageous properties of a completely encapsulated housing.
    The present invention has as its object to provide an operating device for a lamp and a manufacturing method, whereby the problems described above can be avoided and in particular a cost-effective production and improved electromagnetic properties can be achieved.
    According to the invention, this object is achieved by a lighting device for a lighting device according to claim 1 and a method for producing an operating device according to claim 11.The dependent claims define further embodiments of the present invention.
    According to the invention, an operating device for a lighting device is provided which comprises a housing at least one component arranged in the housing. The at least one device may be on a printed circuit board or arranged in any other suitable manner in the housing. The housing is potted with a potting compound, wherein in the housing a non-potting filled with air bubble is present. The air thus trapped in the housing of the operating device prevents complete filling of the housing with the potting compound, so that the problems explained in connection with the prior art can be avoided. Since a part of the housing is not filled with the potting material, it is advantageous to reduce the material with respect to the potting material, which leads to a cost saving in the production of the operating device. Likewise, the EMI behavior, i. the electromagnetic interference characteristic of the operating device can be improved, and the components or circuit elements present in the housing of the operating device can outgas in the housing, which increases the service life.
    The printed circuit board preferably has at least one component which is arranged on the printed circuit board and is not completely cast with the potting compound, i. E. it extends at least partially into the air bubble. In this case, the at least one non-completely encapsulated component is preferably arranged on an upper side of the printed circuit board, while an underside of the printed circuit board is completely encapsulated with the casting compound. According to an advantageous embodiment, in particular components with larger heights, e.g. Capacitors or the like, arranged on top of the circuit board and not or not completely potted with the potting compound.
    The housing comprises according to a preferred embodiment, an upper and a separate separate lower housing part, wherein the upper housing part is inserted into the lower housing parts. The air bubble is preferably located in the upper housing part above the printed circuit board, while the lower housing part has an opening for filling the Ver¬gussmasse, i. the potting compound is thus filled into the housing via the lower housing part, the two housing parts being held in such a way that air remains trapped in the upper housing part. The two housing parts can be designed in the form of Gehäusescha¬len.
    In one embodiment, the housing is potted with the potting compound in such a way that the potting compound extends only over part of the outer surface of the upper housing part. In this embodiment, in particular, at least the upper side of the upper housing part can remain free of the potting compound. The advantage of this Ausführungsbei¬ game consists in a low material consumption of the potting material, resulting in a cost reduction in the manufacture of the operating device.
    In a further embodiment, the potting compound surrounds the outer surface of the upper housing part completely, so that the potting compound extends over the top of the upper housing part. In this embodiment, it is advantageously achieved that reverse engineering is made considerably more difficult and the operating device can fulfill a high safety standard.
    In order to achieve a certain safety standard and to use the operating device for certain applications, the housing can be encapsulated with the encapsulation compound for IPxx, so that the encapsulated housing has a certain degree of protection and the particular type of protection corresponds to a specific IP code. Where " IP " for " International Protection ", " xx " indicates the respective type of protection, with the first code of the IP code relating to dust protection and the second code to protection against water. The advantage of realizing a high safety standard for the operating device is that it is possible to use the device for a variety of possible applications requiring special protection against water or dust, etc. This is particularly important for applications outside of buildings (e.g., street lighting) or for applications where there is the potential for contact with water (e.g., aquariums, kitchens).
    The present invention is generally applicable to all types of lighting equipment such as electronic ballasts, controllers, transformers, or the like. According to one embodiment, the operating device may in particular be a LED converter for a LED lighting device.
    Furthermore, the invention comprises a method for producing such a Be¬triebsgerätes, wherein first the circuit board is inserted with the at least one component in the housing. Subsequently, the housing is potted with the potting compound, so that the non-potting filled with air bubble remains in the housing. Preferably, at least one device of the devices disposed on the circuit board is not completely potted with the potting compound and at least partially extends into the air bladder.
    [0016] If the operating device has two housing parts, the filling of the potting compound is preferably carried out via the lower housing part.
    In the following, embodiments of the invention will be described in detail with reference to the drawing.
    FIG. 1 shows an operating device according to the invention with an externally partially encapsulated housing.
    2 shows, by way of example, a further preferred embodiment of a control gear according to the invention, in which the housing is completely potted on the outside.
    Fig. 3 shows an illustration for explaining a method for producing a
    Operating device for a light source according to an embodiment of the invention.
    1 shows a housing 1 of an operating device for a lighting means. In the housing 1 is a circuit board 4, on which at least one component 5 is arranged. In FIG. 1, different components 5 are shown by way of example realize certain control functions for a light source. For example, the operating device may be an LED converter. The printed circuit board 4 is connected to a connecting cable 9 for connection to an external connection.
    In the illustrated embodiment, the housing 1 comprises two separate Gegehäuseteile 2.3 in the form of housing shells. In the housing 1, a potting compound 6 is filled with a container 10 via an opening 8 formed in the lower housing part 3, so that the potting compound rises from the bottom of the lower housing part 3 during filling of the potting compound, thereby filling the lower housing part 3 and into the upper one Housing part 2 passes. In the illustrated embodiment, the potting compound fills the upper housing part 2 only partially such that an air bladder 7 is present in the upper housing part 2. The air bladder 7 thus prevents a complete filling of the housing 1 with the potting compound.
    The air bubble 7 is formed so that at least one of the components 5 at least partially extends into the air bubble and thus is not completely surrounded by the Vergussmaterial7. The underside of the printed circuit board 4 is preferably completely covered by the Verguss¬ mass 6, so that the area of the housing 1 below the circuit board 4 is completely filled with the potting compound 4.
    The upper housing part 2 is inserted into the lower housing part 3. In the embodiment of FIG. 1, the potting compound extends only over a part of the outer surface of the upper housing part 2. The upper part of the outer surface of the upper housing part 2 is not surrounded by the potting compound 6. In this embodiment, therefore little Ver¬gussmaterial is used, resulting in a cost reduction in the manufacture of the operating device 1.
    If the filling of the housing 1 with the potting compound 6 is completed, the potting compound 6 can cure in the housing 1.
    The housing 1 may be formed in a preferred embodiment and potted with the potting compound 6 that it realizes a certain degree of protection, which corresponds to a certain IP code.
    Fig. 2 shows another embodiment of an operating device 1. The arrangement of the various components of the operating device corresponds to the arrangement of Fig. 1, where in contrast to Figure 1 in this embodiment, the potting compound 6 is filled in the lower housing part 3 in that the outer surface of the upper housing part 2 is completely surrounded by the potting compound 6. The advantage of this embodiment is that reverse engineering is made considerably more difficult and an increased safety standard of the housing can be achieved.
    Fig. 3 is a diagram for explaining a method of manufacturing an operating apparatus according to the present invention.
    In a step S1, a printed circuit board with at least one component is first inserted into an upper housing part of a housing. In a subsequent step S2, the upper housing part is inserted into a lower housing part of the housing. In a step S3, a potting of the housing with a potting material takes place, wherein the potting material is filled via the lower housing part such that in a step S4 an air bubble enclosed in the housing, preferably in the upper housing part thereof, remains.
    Alternatively, within the scope of the invention, an operating device for a lamp can be provided, which comprises a housing and components arranged therein, which are connected to each other, for example by means of a crimped connection (clip connection). In this case, the components are not arranged on a circuit board, but connected to each other and are used together in the housing.
