Definitions

  • the present invention relates to a lamp according to the preamble of claim 1 and an adapter for such a lamp according to claim 15.
  • Various systems are known in the field of luminaires for mounting at least one luminaire with at least one illuminant on, in or on a holder on e.g. a wall, a ceiling, a piece of furniture or the like.
  • a bracket is firmly attached to the wall, the ceiling, etc., in or on which at least one lamp can then be mounted.
  • the luminaire can only be fastened in exactly one place in the holder or it can e.g. in the case of cable systems or in the case of rail systems, at least one lamp can be variably attached at least along a longitudinal direction of the holder.
  • the lamp can also be designed to be able to be moved on or in the holder.
  • Several lights can also be attached to, in or on the same holder.
  • holders of this type in the form of rail holders usually have a body which is long and rigid in the longitudinal direction as a rail and which, for example, by means of screws e.g. can be firmly attached in holes in the wall, ceiling, etc.
  • the luminaire can be placed on or in the rail and held in this way.
  • This can be done via an adapter, which can be connected to the lamp on one side and designed for fastening on or in the rail on the other side.
  • the adapter can be designed to be inserted into the rail in a first rotational position about its vertical axis in a first direction of the vertical axis and to be held in the rail in the opposite direction of the vertical axis by rotation about the vertical axis, e.g. by an engagement inside the rail that can be caused by the rotation.
  • the housing can have a fastening means in the form of a housing nose on each side in the direction of the longitudinal axis towards the rail, which can protrude into the rail in such a way that the housing lugs can be gripped laterally on both sides in the direction of the transverse axis. If the adapter and the housing including housing lugs are firmly connected to one another in this state, the housing lugs engaging in the rail can prevent the adapter from rotating about the vertical axis and thereby secure the adapter in the second rotational position.
  • the housing on the lamp e.g. Arranged around a lamp extension between the adapter and the illuminant and is both displaceable in the direction of the vertical axis and rotatable about the vertical axis. If the adapter was brought into the held state in the second rotational position, the housing can be rotated about the vertical axis and displaced in the direction of the vertical axis via the adapter such that the housing lugs engage in the rail.
  • the housing and the housing lugs are usually fastened in this position by means of a nut with an internal thread, which is arranged around the lamp extension between the lamp and the housing.
  • the lamp extension has an external thread in the area in which the nut for fastening the housing is to be arranged.
  • the second step usually requires two hands because the housing has to be moved in the direction of the vertical axis towards the rail and held there with one hand, while the other hand is used to move and then screw the nut onto the external thread of the lamp extension. This can be very inconvenient and uncomfortable for the user, especially when mounting overhead and on a ladder.
  • the EP 3 091 276 A1 describes a lamp for fastening in a holder, in particular in a rail holder, with an adapter for engaging in the holder, the adapter in a first Rotational position inserted about a vertical axis in the holder and can be held in a second rotational position about the vertical axis in the holder in a direction of the vertical axis, and with at least one fastening means for engaging in the holder, the fastening means in the second rotational position of the adapter the holder can be inserted so that the adapter is secured in the second rotational position.
  • the engagement of the fastening means in the holder can be secured by the spring force of a spring element, the adapter and the fastening means being movable relative to one another in the direction of the vertical axis and being rotatable relative to one another about the vertical axis.
  • the EP 3 086 031 A1 describes a similar luminaire for fastening in a holder, in particular in a rail holder, in which instead the fastening means by rotating the adapter about the vertical axis from the first rotational position of the adapter into the second rotational position of the adapter by contacting the holder against the spring force of the spring element can be moved so that the fastener does not block the rotational movement of the adapter.
  • An object of the present invention is to provide a lamp of the type described in the introduction, so that the mounting of the lamp on, in or on a holder can be further simplified for the user. This should be done as simply, inexpensively and / or safely as possible. Additionally or alternatively, the fastening means should be as inconspicuous as possible for the user. At least an alternative to known lights of this type is to be created.
  • the present invention thus relates to a luminaire for fastening in a holder, in particular in a rail holder, with an adapter which is embodied in a first rotational position about a vertical axis in the holder and in a second rotational position about the vertical axis in the holder
  • the adapter having a mounting projection which is designed to be rotatable about the vertical axis such that the mounting projection in the first rotational position releases the insertion of the adapter into the mounting and holds the adapter in the mounting in the second rotational position can.
  • such a lamp has a mounting projection, which can be aligned with the mounting by rotating about its vertical axis in such a way that the mounting projection coincides sufficiently with a receiving opening of the mounting in the first rotational position about the vertical axis, so that the adapter is inserted into the direction of the vertical axis in the receiving opening of the holder is not hindered.
  • the adapter is in the receiving opening of the bracket positioned, the bracket projection can be brought into its second rotational position by rotating about the vertical axis, in which the bracket projection can bring about a preferably form-fitting hold against the insertion direction along the vertical axis, for example by engaging behind a receptacle of the bracket, so that the lamp by means of the adapter in the Bracket can be held.
  • the lamp according to the invention is characterized in that the adapter has a securing element which is designed to be moved perpendicular to the vertical axis between a release position and a securing position, the securing element also being designed to release the rotational mobility of the mounting projection in its release position and in its securing position to prevent.
  • the securing element can move between its release position and its securing position radially to the vertical axis.
  • the securing projection in its second rotational position can be secured by the securing element in its securing position, preferably by means of a positive and / or non-positive mechanical connection between the body of the securing projection and the securing element or other elements of the adapter. Options for such a mechanical connection are preferably described in more detail below.
  • the securing element can be arranged fixedly along the vertical axis relative to the adapter, so that the height of the securing element is automatically maintained when it is installed on the ceiling.
  • the mounting projection is formed in one piece or in one piece with a mounting element, the mounting element having a recess which extends away from the vertical axis and is oriented at a fixed angle about the vertical axis to the mounting projection, and wherein the securing element is one Has projection, which is designed to engage in the securing position in the recess of the mounting member.
  • a one-piece design of the mounting projection with the mounting element is to be understood to mean that these elements are manufactured separately and then assembled to form a common component.
  • a one-piece design of the mounting projection with the mounting element is to be understood to mean that these were made together from one material and thus form a common component without further assembly steps.
  • a recess is to be understood as the absence of a material of an element.
  • a recess can also be referred to as an opening or recess.
  • the recess of the holding element extends radially away from the vertical axis and is thus oriented in the direction in which the securing element can be moved from its release position into its securing position and vice versa.
  • This fixed angle about the vertical axis is to be selected such that, in the second rotational position of the mounting projection, it can, as described above, perform its holding function with respect to the mounting and in this rotating position the recess of the mounting element is radially aligned with the axis on which can be moved radially to the vertical axis along the securing element or its projection between its release position and its securing position.
  • the mounting projection can be secured in its second rotational position by bringing the projection of the securing element radially toward the vertical axis into its securing position and engaging with its projection in the recess of the mounting element.
  • the lamp has an operating element which is designed to be rotatable about the vertical axis, the operating element being further configured to be rotated about a vertical axis by a user, and the operating element being designed and arranged such that it cannot rotate relative to the mounting element is.
  • Such an operating element can be designed as a separate body of the adapter.
  • the control element can in particular be arranged and designed to be easy to handle for a user in order to be reached and operated by the user with his fingers.
  • the control element can also be designed to be visually appealing to the user, which may not be necessary for the other parts of the adapter, in particular if they do not appear to the outside when used.
  • the user can use the control element to rotate the mounting element between its first and second rotational positions. In this way, the mounting element and in particular its mounting projection can be made accessible to the user from the outside.
  • the operating element has a recess which coincides with the recess of the holding element.
  • Providing the control element with a recess as described above and letting it coincide with the recess of the mounting element can make it possible to ensure the interaction of the securing element and mounting element described above through the control element.
  • a projection of the securing element can simultaneously engage in the recess of the operating element and in the recess of the holding element in order to achieve the effect described above.
  • the lamp has a rail element which is designed to be inserted into the holder and at least substantially, preferably completely, to be received by the holder about the vertical axis, the rail element being designed to be non-rotatable with respect to the holder, wherein the bracket projection relative to the rail element is designed to be rotatable about the vertical axis.
  • the rail element as part of the adapter of the lamp is preferably longer in a preferred direction of extension perpendicular to the vertical axis than to the further direction of extension perpendicular thereto, which can result in an elongated rail-like appearance of the rail element, which can lead to the designation as a rail element.
  • the rail element can serve direct contact of the adapter with the holder and for this purpose are at least essentially taken up by the holder about the vertical axis.
  • the rail element allows the rail element to engage in the holder from the inside, so that the mechanical connection between the adapter of the lamp and the holder can remain hidden from the holder itself for the user. This can improve the optical appearance of the adapter or the lamp in the assembled state for the user. If the rail element is preferably completely absorbed by the holder, this effect can be increased or improved.
  • the rail element is in this case secured against rotation by the holder, so that the rail element can only be moved translationally in the direction along the vertical axis and radially to the vertical axis, but rotational movements can be prevented by the mutual blocking of the rail element and holder.
  • the mounting projection Since the mounting projection is at the same time rotatable about the vertical axis relative to the rail element, the mounting projection can be moved by a rotary movement about the vertical axis between the first rotational position and the second rotational position and thus prevent the adapter from moving in the second rotational position against the insertion direction along the vertical axis .
  • the securing element is designed to be movable relative to the rail element perpendicular to the vertical axis.
  • the rail element is designed to at least substantially, preferably completely, accommodate the holding element.
  • the mounting element can be hidden from the user to the extent that the rail element itself can be received by the mounting. This can preferably be done completely. As a result, the optical impression of the adapter or the light for the user can always be improved by the functionally interacting mechanical elements being concealed from the outside.
  • the rail element has a first rail element part and a second rail element part, preferably consists of a first rail element part and a second rail element part, the securing element engaging around the two rail element parts in sections such that the two rail element parts are held together by the securing element .
  • the rail element can be formed in two parts, the two rail element parts preferably being of identical design and being able to interact with one another in such a way that they together form the rail element.
  • This can keep the manufacturing costs of the rail element low because two identical parts are used and therefore only one type of rail element part has to be manufactured.
  • This advantage can be increased particularly in that the rail element consists exactly of the two rail element parts and no additional additional elements are used to form the rail element.
  • this can also be simplified in that the securing element engages around the two rail element parts in sections such that the two rail element parts are held together by the securing element.
  • Such gripping can take place, in particular, perpendicular to the elongated direction of extension of the rail element and the securing element, i.e. perpendicular to the direction radial to the vertical axis, on which the securing element can be moved between its release position and its securing position.
  • This direction can also be referred to as the transverse direction of the rail element.
  • additional means for connecting the two rail element parts such as e.g. mechanical locking elements and / or cohesive connections by adhesive and the resulting material and assembly time, are dispensed with.
  • the securing element in addition to the previously described function of securing the mounting projection in its second position, can have the further function of holding the two rail element parts together. This can keep the number of components of the adapter used and the assembly steps required for this particularly low.
  • the holding element has a holding area and a transition area along the vertical axis, the transition area perpendicular to the vertical axis being smaller than the holding area, and the two rail element parts each having a constriction element which are designed to form the transition area of the holding element to grip together in such a way that the holding area can be held by the constriction elements in a direction of the vertical axis.
  • the mounting element along the vertical axis with its mounting area has a portion of its mounting element body that is wider or thicker than an adjacent transition area radially to the vertical axis.
  • a holding area can be created on the head side of the holding element, which can bring about a form-fitting hold in the direction of the vertical axis against the insertion direction in relation to the narrowing elements of the rail element.
  • the constriction elements can encompass the transition area.
  • the constriction elements are correspondingly radial to the vertical axis formed such that the transition area of the mounting element is not touched and at the same time the mounting area can be held in a positive manner in the direction of the vertical axis.
  • This can allow a secure hold in the direction of the vertical axis of the mounting element by the rail element and at the same time ensure the relative rotational mobility of the mounting element with respect to the rail element about the vertical axis.
  • the latter can ensure that the mounting projection of the mounting element, as described above, can be rotated about its vertical axis between its two rotational positions with respect to the rail element.
  • the mounting element must be arranged with its mounting area in two corresponding mounting element receptacles of the mounting rail parts before the assembly of the two rail element parts. This applies accordingly to the transition area of the mounting element between the two constriction elements of the rail element parts. Only then are the two rail elements joined and secured to form the rail element.
  • the lamp has a spring-elastic contact element which is designed to be spaced from an electrical conductor of the holder in the release position of the securing element and to contact the electrical conductor of the holder in the securing position of the securing element, the securing element being a Comprises pressure element with a wedge-shaped area, which is designed to deflect the resilient contact element during the movement of the securing element from the release position into the securing position towards the electrical conductor of the holder.
  • Such a spring-elastic contact element is to be understood as an electrically conductive body which, due to its material properties and its dimensions, is designed to be resiliently deformed in a spatial direction with respect to a fixed section and to be able to bend back automatically into the starting position due to the spring force.
  • An electrical conductor such as a sheathed copper cable, can be connected to the fixed section, so that this area of the spring-elastic contact element or its contact element body can also be referred to as a connection area.
  • the contact element body of the spring-elastic contact element can extend away from this connection area in such a way that the spring-elastic bending behavior described above can be enabled perpendicular to this direction of extension in at least one spatial direction.
  • the resilient contact element can be arranged in the adapter or in the rail element in such a way that the resilient contact element can be bent towards an electrical conductor of the holder in order to contact it and thereby an electrically conductive connection between an electrical To produce conductors of the holder and the electrical conductor of the lamp according to the invention connected to the connection area of the contact element body.
  • the resilient bending of the resilient contact element towards the electrical conductor can be carried out by a pressure element of the securing element, which can be wedge-shaped for this purpose.
  • the tip of the wedge-shaped area of the pressure element of the securing element can thus point radially towards the vertical axis and continuously widen in a transverse direction perpendicular to the translational radial direction of movement of the securing element between its release position and its securing position.
  • the resilient contact element can be increasingly bent through the wedge-shaped area of the pressure element of the securing element towards the electrical conductor of the holder when the securing element is pushed or pressed by the user from its release position radially to the vertical axis in its securing position.
  • the resilient contact element has been bent sufficiently from the wedge-shaped area of the pressure element of the securing element towards the electrical conductor of the holder in order to contact the electrical conductor of the holder and to establish an electrically conductive connection. Due to the resilient properties of the resilient contact element, this electrical contact with the electrical conductor of the holder can be canceled by the user moving the securing element radially from the securing position away from the vertical axis into its release position, since this also causes the wedge-shaped area of the pressure element of the securing element is removed again from the resilient contact element and this resiliently can return to its initial position in which the resilient contact element is spaced from the electrical conductor of the holder.
  • the securing element in addition to the function of securing the mounting projection in its second rotational position, can also perform the function of making electrical contact between the adapter of the lamp and the mounting.
  • this function can be implemented without the user having to take any further measures or without additional components of the adapter of the lamp being required for this.
  • This can allow a particularly simple implementation of the functions described above. Since additional components can be dispensed with at the same time, the costs for implementing these functions can also be kept low. This can also apply to the required installation space, since the functionality described above can be implemented within the securing element or within the rail element.
  • the resilient contact element has a contact projection for contacting the electrical conductor, the rail element, preferably the first rail element part or the second rail element part, having a through opening for the contact projection of the resilient contact element.
  • the contact projection in particular in the release position of the securing element, can at least partially or preferably completely disappear in the rail element, so that the insertion of the adapter into the holder in one direction along the vertical axis cannot be hindered by the contact projection of the resilient contact element.
  • This can also protect the contact projection from damage etc. when not in use. Furthermore, damage from the contact protrusion to other elements such as e.g. packaging of the adapter of the lamp can be prevented.
  • the securing element has a latching element which is arranged in a latching receptacle of the rail element, the latching element being designed to be moved within the latching receptacle of the rail element by the release position of the securing element in its securing position and to latch in its securing position .
  • the securing element can be automatically secured in the securing position. This can ensure that the securing position of the securing element is maintained once it has been effected by the user, so that the bracket projection in its second rotational position can also be indirectly secured as a result. To effect this via such mechanical means can make it possible to remove this securing position again without destroying it.
  • Realizing this via a snap-in receptacle can be mechanically simple, inexpensive and saves installation space, and can be implemented by an integral design of the rail element or the rail element parts.
  • Letting the locking element of the securing element run in a locking receptacle of the rail element can simultaneously limit the translational mobility of the securing element to the extension of the locking receptacle of the rail element and thereby exert a leading effect.
  • the course of the latching element of the securing element in the latching receptacle of the rail element can also simultaneously ensure that the securing element cannot be removed from the rail element or that this is made sufficiently difficult to prevent unintentional removal. At the same time, this can cause the securing element to hold on the rail element and still enable its translational mobility.
  • the mounting projection is designed to engage laterally to the adapter, preferably laterally to the mounting element, in the mounting, preferably in a receptacle of the mounting, in its securing position.
  • the adapter of the luminaire according to the invention can be at least partially accommodated inside the holder and thus hidden from the user's view.
  • a secure hold of the corresponding elements of the adapter can also be achieved in this way, since these can at least partially encompass the holder in some spatial directions and thereby be held in a form-fitting manner.
  • the bracket projection can provide a secure hold relative to the bracket or its corresponding receptacle. Overall, this can result in a simple, secure and space-saving and visually appealing hold of the adapter of the lamp in the holder. This can apply in particular to a holder as a rail holder.
  • two mounting projections opposite one another with respect to the vertical axis are provided, preferably two securing elements opposite one another with respect to the vertical axis are provided.
  • the two holding projections opposite one another with respect to the vertical axis which can be operated and act together, as previously described for a holding projection, can in particular improve the hold in the holder for the adapter of the lamp.

  • a stable and permanent arrangement of the lamp along the vertical axis relative to the holder can be ensured, which can improve the visual impression for the user with regard to the lamp or achieve the desired view.
