Definitions

  • the invention relates to a lamp with a pivotable and detachable light head.
  • Such a luminaire is known from the prior art, for example in the form of a recessed ceiling luminaire.
  • the light head of the lamp is suitable for receiving a light source and is pivotably and / or rotatably mounted on a holding element or mounting ring. By rotating or pivoting the light head with respect to the holding element, the direction of the light output of the lamp can be changed.
  • the light head and the holding element are permanently built into one another.
  • the complete luminaire i.e. the light head and the holding element, has to be changed or the light head has to be dismantled at least laboriously by loosening several separate fasteners (e.g. screws, nuts, washers, etc.).
  • KR 2012 0036553 A discloses a lighting device with a ceiling lamp which is arranged in an annular mounting element and which is pivotably and detachably connected to coupling holes in the mounting element via a telescopic pivot rod and a rotation rod formed integrally with the lamp.
  • the lamp holder for a lamp.
  • the lamp holder has an outer ring with a cylindrical outer wall, with which the lamp can be inserted into installation openings and can be fixed in the installation openings by holding elements arranged on the outer ring.
  • the lamp holder also has a pot-shaped inner ring which, inserted into the inner diameter of the outer ring, is fixed on the outer ring so as to be pivotable about a pivot axis transverse to the central axis of the outer ring and into which a lamp can be inserted and pivoted with the inner ring.
  • the invention is based on the object of providing a correspondingly improved lamp.
  • the luminaire should enable the light head to be changed easily, that is to say without dismantling the holding element or laborious dismantling.
  • the invention relates to a luminaire, having a light head for receiving a light source, and a holding element, the light head being mounted on the holding element so as to be pivotable about a pivot axis by means of a pivot bearing.
  • the lamp according to the invention is characterized in that the pivot bearing has a first connection part on the holding element and a second connection part on the light head. At least one of the connecting parts has a first latching element that is pretensioned towards the other connecting part when viewed in the direction of the pivot axis.
  • the first latching element interacts with a corresponding second latching element of the other connecting part - that is to say at least by virtue of its pretension - in such a way (non-positively) around the
  • the light head and the holding element can be detachably connected in an assembly direction essentially transversely to the pivot axis and pivotably around the pivot axis.
  • the invention has the particular advantage that due to the prestress acting essentially perpendicular to the direction of installation - that is, the force-fit connection - the light head can be installed and removed quickly and easily. For this purpose, only the light head needs to be guided in the assembly direction relative to the holding element. For example, all that is required for dismantling is a manual tensile force that exceeds the preload of the first latching element.
  • the light head and the holding element are thus provided in a simple manner in a modular manner.
  • the structure of the pivot bearing can also be simplified overall.
  • separate fastening means can be dispensed with, since the pretensioning function, which is used for easy (dis) assembly and also for storage, is provided in an integrated manner in the pivot bearing.
  • the first latching element preferably has a latching part which is formed in such a way as to protrude at least partially in the direction of the pivot axis towards the second latching element; that is, has a protruding area.
  • the second latching element has a recess corresponding to the latching part, in which the first latching element - preferably at least by means of its protruding area - is detachably received and pivotable about the pivot axis and, in particular, is latched into place.
  • the locking part and the recess thus allow an effective interaction of the two locking elements to form the non-positive connection and thus the pivot bearing.
  • the latching part is preferably rounded, round or spherical in at least one area in which it interacts with the second latching element - preferably in the protruding area.
  • the locking part is preferably spherical; so a ball. Accordingly, the latching part and the second latching element can be brought into an interaction position and securely held there independently of a pivot angle of the pivot bearing formed in this way. The forces exerted by the preload can also be evenly distributed.
  • a spherical design in particular allows a simple, since geometrically dependent automatic centering of the pivot bearing components and thus the components of the light head and holding element ..
  • the first latching element preferably has an elastic element for pretensioning along - that is, in the direction - of the pivot axis and preferably for pretensioning the latching part, in particular towards the other connecting part.
  • the elastic element can for example be designed as a spring and in particular a helical spring. Accordingly, the first latching element can be constructed from simple components which at the same time allow reliable and effective pretensioning.
  • the first latching element preferably also has a sleeve in which the elastic element and the latching part are received to form a pressure piece.
  • the sleeve can preferably have spring support areas for captive storage of the spring viewed in the direction of the pivot axis.
  • the sleeve can have locking part support areas for captive storage of the locking part, viewed in the direction of the pivot axis.
  • the design as a pressure piece enables the use of simple components to provide the first latching element.
  • the spring support areas are preferably arranged opposite the latching part with respect to the spring and allow a simple and weight-saving provision of a securing device for the spring.
  • the latching part support areas are preferably arranged opposite the spring support area with respect to the spring and allow a simple and weight-saving provision of a securing device for the latching part and thus the components of the first latching element as a whole.
  • a pressure piece can thus be handled separately and thus easily made available as part of the pivot bearing.
  • the first connecting part preferably has two receiving jaws and a spring element.
  • the two receiving jaws are arranged to encompass the first latching element, preferably the sleeve or a bearing housing carrying the sleeve.
  • the spring element is arranged in such a way that it at least partially engages around the receiving jaws in order to press the receiving jaws against the first latching element in order to fasten the first latching element, preferably the sleeve or the bearing housing, to the holding element. Accordingly, there is a simple but firm and secure attachment of the first latching element to the holding element.
  • the spring element is preferably a wire spring or a leaf spring. This is advantageous in terms of production technology and also allows particularly simple handling when attaching the spring element to the receiving jaws.
  • the receiving jaws are preferably formed from plastic. This material is particularly suitable for realizing suitable elastic properties of the receiving jaws. Overall, the entire holding element made of plastic or Metal (e.g. sheet metal) or other known materials for lamp bodies.
  • the light head can also be made of plastic or metal (for example sheet metal or aluminum) or other known materials for light bodies.
  • the receiving jaws and the holding element are preferably formed in one piece with one another, as a result of which both manufacture and assembly are simplified and few individual parts are required.

  • the first connection parts are preferably provided on opposite sides of the holding element, preferably on the inside, and the second connection parts on opposite sides of the light head, preferably on the outside. This enables a stable connection, which is provided and supported on both sides, by the pivot bearing.
  • the light head preferably has at least two webs which extend on both sides of the second connection part essentially in the assembly direction in order to guide the first connection part to the second connection part during the assembly of the light head and the holding element. Accordingly, the assembly of the light head on the holding element can be carried out easily in a defined guide.
  • the light head has a stop in its mounting direction (i.e. the relative direction of movement of the light head for mounting along the mounting direction) in front of the second connecting part, in order to stop the first connecting part in a connecting position of the connecting parts when the light head and the holding element are mounted.
  • the stop defines an end position in the assembly direction.
  • the stop and the webs preferably form a U-shaped assembly guide. This results in a clear assembly direction. All of this leads to a further simplification of the assembly.
  • the holding element preferably has an opening in which the light head is detachably and pivotably received.
  • the holding element can preferably be formed as a ring which delimits the opening on the circumferential side.
  • the opening enables the light head to be easily inserted up to its connection position and sufficient play for its pivoting. Is provided as a closed ring the holding element is also provided in a dimensionally stable manner and can safely function as an installation ring.
  • the width of the light head preferably decreases, preferably steadily, at least in the area of the pivot axis and particularly preferably at least in a ramp section starting from the second connecting part in the direction of its (i.e. the light head) assembly direction.
  • the light head particularly preferably has a substantially frustoconical shape. The light head thus forms a type of lead-in bevel on its outer surface, which enables simple and defined guidance of the light head during its assembly up to its connection position with the holding element.
  • the light head preferably also has a light source, such as an LED light source (LED: light-emitting diode), for emitting light from the lamp.
  • a light source such as an LED light source (LED: light-emitting diode)
  • LED light-emitting diode

  • Such a light source basically has a comparatively low weight with high efficiency and a long service life.
  • the pivot axis preferably extends essentially perpendicular to an optical axis of the luminaire and preferably the main emission direction, which are generally identical.
  • the light output can thus also be provided and adjusted as uniformly as possible with a view to a possible pivoting range.
  • the light head is preferably arranged in a (swivel) range from -90 ° to + 90 ° or -60 ° to + 60 ° or -45 to +45 or -30 to +30 with respect to the holding element so that it can be swiveled on the latter.
  • the invention is not restricted to the preceding value ranges. In principle, any swivel range is conceivable. It is also conceivable that the pivoting ranges differ on each side. The luminaire thus enables any swivel range to be selected and can therefore be used in a wide range of applications.

  • the lamp 100 or the holding element 2 can also have a holding ring 7. By means of this, for example, the holding element 2 can be fixedly mounted on the luminaire housing 101.
  • the retaining ring 7 is part of a sliding ring bearing in order to be able to rotate around the retaining element 2 - here preferably around a vertical axis extending in the assembly direction Z2 - and thus to increase the degrees of freedom of the alignment of the light head 1.
  • the luminaire 100 When the luminaire 100 is in operation, a user can manually pivot the light head 1 about the pivot axis X6 (and, if necessary, also rotate it about the vertical axis) in order to adjust the alignment of the light output.
  • the first connecting parts 8 exert holding forces on the second connecting parts 10 in the direction of the swivel axis X6, so that a swiveling holding or latching connection is provided.
  • the light head 1 is preferably snapped onto the holding element 2 by means of spring forces.
  • Several partial areas of the lamp 100, or of the light head 1 and the holding element 2 can be designed to be conductive, for example made of metallic materials, in order to be able to conduct an electrical current through the holding element 2 and the light head 1 to the light source.
  • each latching part 16 is preferably pressed against the upper edge of the recess 18 shown here. Due to its spherical shape, the force acts obliquely on the ball 16 so that a portion of the force results in the direction of the pivot axis X6, as symbolized by the arrow 16.4.
  • the latching part, or each latching part, of the first latching element could be arranged on the light head and the corresponding recess, or the respective recess, of the second latching element could be provided in the holding element. So the pivot bearing of this alternative embodiment is formed inversely with respect to the embodiment shown.
  • the lamp 100 could have only a single first connection part 8 and a single second connection part 10.
  • the lamp 100 can, for example, have a conventional rotatable bearing opposite this detachable pivot bearing 6 in order to produce a pivot connection around the pivot axis X6 that is securely supported on both sides.
  • the present invention is not restricted to the exemplary embodiment described above, provided that it is covered by the subject matter of the following claims. In particular, all features of the exemplary embodiment can be provided and combined in any desired manner and number. In addition, the present invention is directed independently, in addition to the lamp 100, to a correspondingly configured light head 1.
