Definitions

  • the present invention relates to a lamp with a lamp housing for accommodating a light source and a suspension bracket for suspension—that is, mechanical attachment—of the lamp housing.
  • suspension brackets have the advantage that they are basically easy to manufacture, can be designed in any way and can also carry heavy loads.
  • the suspension brackets can also be designed in such a way that they are at best not visible or only visible with difficulty at the operating location of the lamp.
  • Such suspension brackets can also be easily adapted to different types of lights or used with them.
  • the use of suspension brackets for attachment is particularly advantageous for large-area types of luminaires, since any desired spacing between attachment points on the luminaire body can be selected for simple attachment by appropriately spreading the bracket, in order to achieve optimal load distribution.
  • the present invention relates to a lamp which has a lamp housing for accommodating a light source.
  • the lamp has a suspension bracket for hanging the lamp housing.
  • the suspension bracket in turn has a support leg and at least one or more fastening legs extending away from the support leg.
  • the respective fastening leg has, at its end remote from the support leg, a fastening structure via which the suspension bracket is connected to the lamp housing is attached.
  • the lamp also has a retaining bracket.
  • the holding bracket in turn has a contact leg, which is connected with a contact section to the suspension bracket, lying flat on a flat support side of the support leg facing the lamp housing.
  • the retaining clip has a mounting leg with a mounting section for mounting the lamp on a fastening area.
  • the attachment area can preferably be a suspension or a horizontal cable attachment or an attachment surface or any other type of attachment area.
  • At least the mounting section of the mounting leg is arranged on a side of the support leg that faces away from the contact leg and at a distance from the support leg such that the support leg is provided between the contact leg and the mounting section.
  • the retaining clip also has a connecting leg which connects the contact leg and the mounting leg to one another.
  • connection between the contact leg and the mounting leg can be used flexibly via the connecting leg.
  • a corresponding distance between the mounting leg and the contact leg can be varied as desired by the length of the connecting leg.
  • parts located between the contact leg on the one hand and the assembly leg on the other hand can be bypassed as desired using the connecting leg.
  • the contact leg or at least its contact section is preferably plate-shaped and preferably extends in a contact plane.
  • the contact leg can thus be designed in a particularly simple manner. Basically, with the plate-shaped design, it is also conceivable for the contact leg to have certain structural elements which result in an increase in the stability of the component. For example, the bending of end edges and the like are conceivable here.
  • the mounting leg or the mounting section can also be plate-shaped and preferably extend in a mounting plane. The same applies here as was said above with regard to the plate-shaped contact leg.
  • the system level and the assembly level can be aligned parallel to one another. As a result, the force is distributed as evenly as possible.
  • the contact leg and the mounting leg can be designed in the same way for easy resting on corresponding fastening areas or on the carrier leg. This not only simplifies the production of the retaining bracket, but also enables the lamp to be installed as simply and intuitively as possible.
  • the system level and the assembly level can also be aligned perpendicular to one another.
  • the contact level can be provided in the manner described above for horizontal, flat support, while the mounting level can be configured, for example, in a defined vertical alignment.
  • the mounting level can thus be designed, for example, for insertion into a fastening area designed as a corresponding opening. It is also easy to mount, for example, on a cable attachment.
  • the mounting portion may preferably have a clamp structure to clamp a part of the mounting portion for mounting the lamp; this preferably solvable.
  • the clamping structure can particularly preferably have a cable bushing for accommodating a cable section of a cable attachment to be clamped as the attachment area.
  • the cable attachment can, for example, run vertically as a suspension to form a pendant lamp or horizontally. In this way, a simple installation of a lamp can be made possible.
  • the connecting leg may preferably be separated into two sections which are connected for relative rotation about a pivot axis to selectively change the position of the mounting leg relative to the abutment leg. It is thus possible, for example, to pivot the mounting leg or its mounting section by a certain amount—for example, about a horizontally aligned axis of rotation. It is thus possible, for example, to use the mounting leg to mount the light over a large area and thus securely on sloping ceiling sections.
  • One of the sections can preferably be formed integrally with the mounting leg. Alternatively or additionally, it is preferably conceivable that the other section is formed integrally with the contact leg.
  • the two sections can preferably each have a flat rotating section, which preferably lie flat against one another in a rotating plane perpendicular to the axis of rotation. At least one or both of the sections can preferably extend along a plane, preferably along the plane of rotation.
  • the two sections can also have corresponding structural sections distributed around the axis of rotation, by means of which defined angular positions of the two sections relative to one another around the axis of rotation can be adjusted through interaction.
  • the two sections can also have part of an angle indicator, by means of which the relative angular position of the two sections with respect to one another around the axis of rotation can be read off.
  • the rotatable design of the connecting leg can be designed in any way in order to provide the simplest possible, flexible but nevertheless secure light fixture. Detailed explanations of the above-described features of the connecting leg are given below.
  • the contact limb can have at least one extension section which rests flat against the or one of the fastening limbs. In this way, the bearing surface of the contact leg can be further increased. Due to the resulting greater distribution of the load, an even more secure fastening of the lamp can be provided, since a type of double-layer holding structure is created in this way. This also increases the rigidity of the entire light fixture.
  • the contact limb can also have a plurality of extension sections, which can then each lie flat against one of the fastening limbs. In this way, the effect of the extension sections can be further increased.
  • the load can be distributed in different directions, which can be advantageous in the event of lateral forces on the light (e.g. wind loads when used outdoors).
  • a safe distribution of force can also be provided in the event that the luminaire should be equipped with a twistable connecting leg.
  • the extension section or sections can preferably extend away from the contact section; and preferably closed. In this way, a large contact leg is provided. The stability of the contact leg is further increased by the flowing, integral transition from the contact section to the extension section.
  • the extension section or sections can preferably each be designed in the form of a plate and more preferably each extend in one extension plane.
  • the extension section can also be produced in a particularly simple manner.
  • the contact plane if present, can particularly preferably be inclined with respect to the plane(s) of extension, which results in particular stability of the contact leg designed in this way in three dimensions.
  • suspension bracket has a plurality of attachment legs, these can extend away from opposite sides of the carrier leg. This can result in a maximum spread of the suspension bracket and the load can particularly preferably be distributed evenly (e.g. symmetrically).
  • the present invention also relates to a lamp having a lamp housing for accommodating a light source.
  • the lamp also has a suspension bracket for suspending the lamp housing.
  • the suspension bracket in turn has a support leg and at least one or more fastening legs extending away from the support leg. At its end facing away from the support leg, the respective fastening leg has a fastening structure, via which the suspension bracket is fastened to the lamp housing.
  • the lamp also has a retaining bracket.
  • the holding bracket in turn has a contact leg which is connected to the suspension bracket with a contact section lying flat on a flat carrying side of the carrier leg.
  • the retaining clip has a mounting leg with a mounting section for mounting the lamp on a mounting area.
  • the attachment area can be any type of attachment area, such as a suspension or a horizontal cable attachment or an attachment surface.
  • the retaining bracket also has a connecting leg, which connects the contact leg and the mounting leg to one another. The connecting leg is separated into two sections which are connected for relative rotation about a pivot axis to selectively change the position of the mounting leg relative to the abutment leg.
  • a particularly simple, flexible and yet secure lamp attachment can be provided by means of the attachment structure described above.
  • a rotatable section of the mounting bracket in the area of the connecting leg, the function of turning and thus increasing the flexibility of the lamp attachment is placed in an area independent of direct attachment points of the mounting bracket to the suspension bracket on the one hand and to the attachment area on the other.
  • the rotatability can also be designed in any way, since it is independent of the attachment of the retaining clip.
  • a rotation of the lamp housing on the one hand in relation to a fastening area and on the other hand around any and arbitrarily oriented axes of rotation can also be provided as desired.
  • One of the sections may preferably be integrally formed with the mounting leg.
  • the other of the sections can preferably be formed integrally with the abutment leg. In this way, a particularly simple and, moreover, particularly stable construction can be provided in each case.
  • the two sections can preferably each have a flat rotary section which rests flat against one another in a plane of rotation perpendicular to the axis of rotation. In this way, a rotating function that is safely guided on the one hand and securely connected and securely supported on the other hand can be provided, which is equally simple, flexible and safe.
  • At least one or both of the sections may extend along a plane; preferably along the plane of rotation.
  • the design of the respective sections can be simplified, while at the same time their function of allowing a safe and easy turning movement is supported.
  • the corresponding sections are not only easy to produce, but also easy and intuitive to assemble.
  • the two sections can preferably have corresponding structural sections distributed around the axis of rotation, by means of which defined angular positions of the two sections relative to one another around the axis of rotation can be adjusted through interaction. In this way it can be made possible that clearly defined angular positions can be set. Because of the structural interaction, not only is there a safe and defined angular position, but the components can also remain safely in the given angular position.
  • the two sections may include part of an angular indicator by which the relative angular position of the two sections about the axis of rotation can be read.
  • this angle display can be provided, for example, by simple notches or recesses.
  • boreholes can be provided in one of the sections, which preferably allow the view of the other section and there—depending on the rotational position correspondingly releases other angle display areas.
  • an exact indication of the angle can be provided accordingly on the elements, so that an arbitrarily fine reproduction and adjustment of the angular position is possible.
  • the support side can preferably be a flat side of the support leg that faces and/or faces away from the lamp housing.
  • a particularly simple and stable lamp attachment can be provided in the case of a support side facing the lamp housing.
  • a particularly simple installation can be made possible in the case of a support side facing away from the lamp housing. If the support side faces both the lamp housing and away, the contact leg encompasses the support leg, which leads to a particularly stable, secure and preferably also rigid lamp attachment.
  • the contact leg according to the second aspect can also preferably have at least one extension section which lies flat against the or one of the fastening legs.
  • the contact limb can also have a plurality of extension sections, which can each lie flat against one of the fastening limbs.
  • the extension section or sections can extend away from the contact leg; preferably closed.
  • the extension section or sections can each be designed in the form of a plate and particularly preferably each extend in one extension plane.
  • the suspension bracket has a plurality of attachment legs, these may extend from opposite sides of the support leg.
  • the advantages result in the same way for the same feature according to the first aspect, to which reference is therefore made at this point.
  • the contact leg or at least its contact section according to the second aspect can also be plate-shaped and particularly preferably extend in a contact plane. If extension sections are present, the contact plane can also preferably be inclined with respect to the extension plane(s) according to the second aspect.
  • the axis of rotation can preferably be aligned parallel to the contact plane and, if present, preferably also parallel to the extension plane(s).
  • the rotary movement can thus be carried out easily with a particularly favorable force distribution.
  • the mounting leg or the mounting section can also be plate-shaped in a lamp according to the second aspect and preferably extend in a mounting plane.
  • the advantages arise in the same way as previously described. In this case it is conceivable that the axis of rotation is aligned parallel to the mounting plane.
  • the suspension bracket and/or the retaining bracket of a lamp according to the second aspect can also be produced as a bent part or a stamped and bent part.
  • the present invention also relates to a lamp, which has a lamp housing for accommodating a light source.
  • the lamp also has a suspension bracket for hanging the lamp housing.
  • the suspension bracket in turn has a support leg and at least one or more fastening legs extending away from the support leg. At its end facing away from the support leg, the respective fastening leg has a fastening structure, via which the suspension bracket is fastened to the lamp housing.
  • the lamp also has a mounting element for mounting the lamp a mounting area.
  • the fastening area can be any type of fastening area, for example a fastening surface such as a wall or ceiling of a room/building.
  • the mounting element in turn has a carrier body with a receiving space for receiving at least part of the carrier leg in a supporting manner in an insertion direction via an insertion opening of the carrier body.
  • the mounting element has a bolt.
  • the latch can be moved between a locking position, in which a locking section of the latch delimits the receiving space on the side of the insertion opening in such a way that the carrier leg inserted into the receiving space is locked towards the insertion opening, and a release position in which the locking section opens the receiving space on the side of the insertion opening exposed for optional load-bearing receiving and removal of the support leg via the insertion opening.
  • a simple, flexible and at the same time secure attachment option can be created by means of the attachment structure described above.
  • the light can be designed flexibly according to the circumstances. So it is conceivable, for example, to enable an equally secure mounting even with a low height of the mounting element, for example with a flat ceiling mounting, in order to provide the lamp as close as possible to a mounting area.
  • the use of a bolt offers the simplest possible, flexible but nevertheless secure and intuitively operable fastening option.
  • the insertion opening can preferably extend into a receiving opening in which a supporting part of the carrier leg is held in a supporting manner when the carrier leg is received in the receiving space.
  • a particularly simple but secure structure for receiving and holding the carrier leg and thus the lamp as a whole can thus be created. This is also particularly easy to produce and can ultimately also be used intuitively by the operator.
  • the carrier body can preferably have a mounting section for mounting the lamps on the fastening area. In this way, a defined section be provided, by means of which a simple and defined yet safe installation of the lamp is made possible in a mounting area.
  • a carrier section in which the insertion opening and, if present, also the receiving opening is/are formed, can preferably extend away from the mounting section.
  • a particularly stable mounting element can thus be provided. This can also be made in a particularly simple manner.
  • the bolt can preferably be moved around a pivot axis between the locking position and the release position.
  • the latch is provided to be movable in a different way and, for example, can be moved in a translatory manner between the locking position and the release position.
  • a combined movement of rotation and translation is also conceivable.
  • the provision of a pivotable or rotatable bolt about a defined pivot axis represents a particularly simple provision of a movable bolt. This can be provided, for example, simply by providing a corresponding screw connection as the pivot point.
  • the pivot axis can also be an imaginary pivot axis, which results, for example, in the case of a bolt that is designed integrally with the carrier body and can be pivoted elastically.
  • the pivot axis can be aligned perpendicular to the direction of use. An overall compact design of the elements can thus be provided.
  • the latch may further include a pivot portion that extends between the pivot axis and the locking portion.
  • the bar can thus be produced in a particularly simple manner. Due to the length of the pivoting section, a possible lever arm on the bolt and the necessary pivoting movement of the bolt to enable movement between the locking position and the release position can also be flexibly adapted to the circumstances and wishes.
  • the bolt can have a manipulation section for manual actuation of the bolt.
  • the manipulation section is preferably exposed to the outside provided.
  • the manipulation section protrudes from the carrier body; preferably in a direction opposite to the direction of use.
  • the bolt can therefore be easily operated.
  • it can be provided to save space.
  • the bolt can be provided by particularly simple means, while at the same time enabling particularly high flexibility and secure attachment.
  • the bolt can have a connecting section, which preferably extends between the pivoting section on the one hand and the manipulation section on the other hand.
  • the pivoting section and the connecting section can particularly preferably extend in a straight line away from one another.
  • the bolt can thus not only be provided in a particularly simple manner. It also enables a particularly high level of flexibility through appropriate design and length of the respective sections. In addition, a high stability of the bolt and thus a secure locking can be made possible by appropriate design of the bolt.
  • the latch can preferably be formed integrally with the carrier body. This can particularly preferably be done by freeing up the material of the carrier body and preferably of the mounting section. In this way, on the one hand, a bolt that is particularly stable in terms of function can be provided. On the other hand, components can still be saved, which in turn facilitates the assembly of a corresponding lamp or at least the assembly element.
  • the bolt is biased towards the locking position.
  • the bolt can always be held securely in the locking position, which further increases the security of the fastening function of the lamp.
  • the lamp can also have a spring element for prestressing the bolt towards the locking position.
  • the spring element is preferably supported on the carrier body; is therefore provided between the carrier body and bolt.
  • a corresponding preload can thus be provided in a simple manner.
  • the corresponding spring force can be set as desired, so that the given requirements can be taken into account in a flexible manner without impairing safety.
  • the spring element can be provided separately.
  • a spiral spring or the like is conceivable here, for example.
  • the spring element is formed integrally with the latch and/or the carrier body.
  • the spring element can be provided as a protruding element of the bolt, which is correspondingly supported on a part of the carrier body (e.g.
  • the mounting element in order to be (further) prestressed preferably when the bolt moves from the locking position to the release position in order to thus always pushing the bolt into the locking position.
  • the integral design enables a particularly simple and inexpensive manufacture with few components.
  • the provision of the spring element as a separate component in turn has the advantage that the desired spring force can be adjusted in any way and in a particularly fine manner.
  • the carrier body or its carrier section can particularly preferably have two webs, which more preferably extend parallel away from the mounting section.
  • the webs can preferably be axially spaced from one another with respect to the pivot axis and/or delimit the receiving space between them and/or extend away from opposite sides of the mounting section, viewed in the axial direction with respect to the pivot axis.
  • a carrier body or a carrier section can thus be provided which has a three-dimensional and therefore particularly stable structure.
  • a carrier body designed in this way can also be provided in a simple manner, for example by bending over corresponding side edges of the mounting section.
  • the provision of the support section in the form of, for example, two or more webs is also advantageous in terms of material, since on the one hand less material is required and on the other hand the component weight is low and the component stability is high at the same time.
  • the carrier body can have a U-shaped cross section. If present, the webs of the carrier section can form the two lateral legs of the U and the mounting section can form the connecting leg of the U. In this way, a particularly simple and at the same time stable carrier body can be provided.
