Definitions

  • the invention relates to a lamp with a lamp head and a lamp arm rotatably connected to the lamp head.
  • Luminaires of the type mentioned are known in principle from the prior art.
  • a lamp is usually an LED spotlight, which can be mounted on the lamp arm at a certain point, for example on a ceiling or wall.
  • the lamp arm is rotatably connected to the lamp head, so that the lamp head can be rotated around two axes of rotation, that is to say around a pivot and a tilt axis, and can be aligned in a corresponding position and / or orientation.
  • Such lights are used, for example, as museum spotlights. It is known to lock the axes of rotation to hold the respective position and / or orientation of the lamp head, i.e.
  • the invention is thus based on the object of creating a lamp of the type mentioned in which the axes of rotation are easier, i.e. H. in particular can be locked faster and more reliably.
  • a lamp according to the invention in particular an LED spotlight, has: a lamp head (for emitting light), a lamp arm, and a swivel joint for rotatable connection of the lamp head with the lamp arm, so that the lamp head can be aligned with respect to the lamp arm via a first and a second axis of rotation of the swivel joint.
  • the lamp also has a locking element which is set up to be moved between a release position in which the lamp head can be aligned via the (i.e. both) axes of rotation, and a locking position in which the (i.e. both) axes of rotation are locked.
  • the (that is, both) axes of rotation can be locked at the same time or released at the same time to align the lamp head.
  • a fitter therefore only has to operate one locking element or perform a locking movement (turning, pulling, pressing etc. of the locking element) in order to lock or hold the lamp head in a defined position and / or orientation.
  • the number of locking elements and locking steps is thus reduced, making the axes of rotation of the lamp easier, i.e. H. in particular can be locked faster and more reliably. Because of the only one locking element, the manufacturing effort is also reduced, so that the lamp is in particular easier to assemble and more cost-effective to manufacture.
  • the lamp also has: a first locking element, which can be moved between a first release position in which the lamp can be aligned via the first axis of rotation, and a first locking position in which the first axis of rotation is locked (blocked), and a second Locking element which can be moved between a second release position, in which the lamp can be aligned via the second axis of rotation, and a second locking position, in which the second axis of rotation is locked.
  • the locking element interacts with at least (or only) one of the locking elements in such a way as to move both locking elements simultaneously between their release position and their locking position.
  • the first locking element is preferably arranged with respect to the second locking element in such a way that by moving the first locking element from the first release position into the first locking position, the second locking element simultaneously moves the second locking element from the second release position to the second locking position is moved. Consequently, the first locking element simultaneously serves as a connecting element for transmitting a movement of the locking element to the second locking element. A particularly compact arrangement of the locking elements can thus be achieved.
  • the first locking element can be arranged with respect to the second locking element in such a way that by moving the first locking element from the first release position into the first locking position, the first locking element comes into non-positive and / or form-fitting contact with the second locking element in order to move the second locking element away from the second To move the release position into the second locking position.
  • the second locking element can be moved reliably into the locking position by means of the first locking element, in particular only by the force of the first locking element for locking the first axis of rotation. By reducing this force, the locking elements can also simply be moved back into the respective release position.
  • the first locking element In the first locking position, the first locking element is in non-positive and / or positive contact with the swivel joint in order to lock the first axis of rotation. Since the swivel joint or the structure of the swivel joint rotates with the first axis of rotation, the first axis of rotation can thus be locked particularly easily by means of the first locking element.
  • the first locking element is a tensioning element which can be moved from the first release position into the first locking position by tensioning (tightening) the tensioning element by means of the locking element.
  • the first locking element can easily be moved into the first locking position, namely in particular only by a single, in particular linear tensioning movement by the locking element.
  • the first locking element or the clamping element can be moved into the first release position by releasing the tensioning element.
  • the tensioning element since the tensioning element is only subjected to tensile stress, the tensioning element can thus be produced simply and with little material, for example as a tensioning strap.
  • the second locking element is preferably in non-positive and / or form-fitting contact with a third locking element, which is non-rotatably provided with respect to the second axis of rotation, around the second To lock rotation axis.
  • the second axis of rotation can thus be locked particularly easily due to the additional friction between the swivel joint and the third locking element.
  • the third locking element is preferably provided non-rotatably with respect to the lamp arm, for example by means of a force fit and / or form fit. Consequently, the third locking element rotates with the lamp arm about the second axis of rotation. In this way, the third locking element can simply be provided non-rotatably with respect to the second axis of rotation.
  • the third locking element can be clamped between the swivel joint and the second locking element in order to lock the second axis of rotation.
  • the locking effect of the second locking element on the third locking element and thus the second axis of rotation can be increased so that the second axis of rotation can be locked particularly easily.
  • the third locking element can be a disk. Because of the particularly thin-walled design of the disk, this benefits efficient production of the third locking element. In addition, a particularly compact arrangement of the second and third locking elements can thus be achieved.
  • the second locking element can be movably received by the swivel joint, in particular movably in a translatory manner, in order to be moved between the second release position and the second locking position.
  • the second locking element can be moved easily, reliably and in a compact manner between the second release position and the second locking position.
  • the second locking element can be designed as a shoe, that is, corresponding to a brake shoe. Due to the massive design of the jaw, the second axis of rotation can thus be locked particularly well in the second locking position. In addition, the stability of a second locking element configured in this way is improved.
  • the locking element is preferably only functionally connected to the first locking element.
  • the locking element is preferred only connected directly to the first locking element, the locking element being indirectly connected to the second locking element, namely via the first locking element.
  • the locking elements can thus be arranged in a particularly compact manner.
  • the locking element can be operated by means of a tool and / or without tools.
  • the force for locking the axes of rotation can be brought about by means of the locking element in a particularly simple manner.
  • the locking element can, for example, have an operating area formed integrally with the locking element, so that the operability of the locking element is improved because of the unnecessary tool.
  • the locking element is a screw (e.g. adjusting screw), so that the locking element can be moved between the release position and the locking position by a screwing movement of the screw, i.e. preferably the first locking element can be moved between the first release position and the first locking position.
  • a screwing movement of the screw i.e. preferably the first locking element can be moved between the first release position and the first locking position.
  • the swivel joint can have an opening, in particular a passage opening, in which the lamp arm is rotatably mounted in order to be rotatable about the second axis of rotation.
  • the lamp arm can thus be particularly easily mounted in the swivel joint so that it can rotate around the second axis of rotation.
  • the lamp preferably has a securing element, for example a securing ring, for axially securing the lamp arm with respect to the second axis of rotation.
  • the third locking element is preferably provided between the securing element and the swivel joint in order to be axially secured with respect to the second axis of rotation. This is of particular benefit to a compact arrangement of the third locking element with respect to the securing element and the swivel joint.
  • the swivel joint can be rotatably mounted in a bearing area of the lamp, preferably rotatably with an inhibition.
  • the inhibition in particular has the effect that the lamp head can maintain a defined alignment (position / orientation) even in the unlocked state or in the first release position, but can still easily be aligned around the first axis of rotation.
  • the first axis of rotation and the second axis of rotation are preferably not aligned parallel to one another.
  • the first axis of rotation is preferably oriented perpendicular to the second axis of rotation. It is particularly preferred if the first axis of rotation is perpendicular to the second axis of rotation.
  • the axes of rotation can thus be arranged particularly compactly with respect to one another.
  • the lamp arm and / or the swivel joint can (each) have a structure, for example a stop, for limiting the rotational mobility of the second axis of rotation.
  • the rotational mobility is preferably limited at an angle of rotation of 360 ° +/- 5 °.
  • the structure on the side of the swivel joint can be provided movably with respect to the swivel joint in such a way that when the structure on the side of the lamp arm interacts (i.e. mechanical contact) with the structure on the side of the swivel joint, the lamp arm in a defined angle of rotation range, in particular in a rotation angle range of 0 ° to 10 °, around the second axis of rotation is still rotatable.
  • a fitter who aligns the lamp head about the second axis of rotation can perceive a haptic feedback shortly before the rotational mobility of the second axis of rotation is limited by the mechanical interaction of the structures.

  • the locking element 60 can be connected to an end region 31 of the tensioning element 30, so that by means of the locking element 60, in particular by moving the nut 61 along the screw shaft 62 or by moving the screw 60 as a whole, this end region is moved away from the swivel joint 4, in order thus to tension (tighten) the tensioning element 30 and in To bring frictional and / or positive contact with the swivel joint 4. That is to say, the end region 31 can have the aforementioned surface with which the nut 61 can be brought into contact.
  • the end region 31 can be formed by the two ends of the tensioning element or tensioning strap 30, which, viewed in the direction of the manipulation direction of the locking element 60, preferably overlap (see, for example Figure 8 ).
  • the end region 31 or the two ends forming the end region 31 can each have a passage opening 32 through which the screw shaft 62 is guided so that the nut 61 is then screwed onto the screw shaft 62.
  • the tensioning element 30 does not have to have an end region 31, so that the tensioning element 30 can also be provided endlessly.
  • the locking element 60 is set up according to the invention to be moved between a release position in which the lamp head 2 can be aligned via the axes of rotation 5, 6, and a locking position in which the axes of rotation 5, 6 are (simultaneously) locked. In the exemplary embodiment shown in the figures, this takes place in that the locking element 60 interacts with at least one of the locking elements 30, 40 in such a way as to move both locking elements 30, 40 simultaneously between their release position and their locking position.
  • the first locking element 30 is arranged with respect to the second locking element 40 in such a way that by moving the first locking element 30 from the first release position into the first Locking position at the same time the second locking element 40 is moved from the second release position into the second locking position.
  • the first locking element 30 is arranged with respect to the second locking element 40 in such a way that by moving the first locking element 30 from the first release position into the first locking position, the first locking element 30 comes into non-positive and / or positive contact with the second locking element 40 in order to thereby also to move the second locking element 40 from the second release position into the second locking position.
  • the first locking element 30 can, for example, at least partially surround the second locking element 40 in order to thus define an area or space in which the swivel joint 4, the second locking element 40 and preferably the third locking element 50 are provided.
  • this area is narrowed or reduced, so that the first locking element 30 comes into non-positive and / or positive contact with both the swivel joint 4 and the second locking element 40, ie clings to the swivel joint 4 and the second locking element 40.
  • the non-positive and / or positive contact between first locking element 30 and swivel joint 4 causes the first locking position, i.e. locking of the first axis of rotation 5 provided by swivel joint 4.
  • first locking element 30 and second locking element 40 causes First, that the second locking element 40 is moved in the direction of the swivel joint 4 and the third locking element 50 in order to finally reach the second locking position, that is to say, for example, to come into non-positive and / or positive contact with the third locking element 50. Consequently, the second axis of rotation 6 is then also locked.
  • first locking element 30 is thus preferably provided as a tensioning element, it at least partially surrounds or wraps around both the swivel joint 4 and the second locking element 30, for example in the form of a circular arc 33 wrapping around the swivel joint 4 and the second locking element 30
  • the space in which the swivel joint 4, the second locking element 40 and preferably the third locking element 50 are provided is thus particularly defined by the circular arc 33, so that the aforementioned narrowing or reduction of this area by tensioning (tightening) the tensioning element 30 and thus Reduction in the diameter of the circular arc 33 is effected.
  • the respective surface of the swivel joint 4 and the second locking element 40 which can be brought into non-positive and / or positive contact with the clamping element 30, has a shape that corresponds to that of the clamping element 30, in particular that of the circular arc 33. It can thus be effected that the swivel joint 4 and the second locking element 40 simply come into flat contact with the clamping element 30.
  • both turning axes 5, 6 can be locked or released at the same time by means of only one locking element 60, that is to say in particular the two locking elements 30, 40 can be moved into their respective locking position.
  • this can take place in that the fixing element 60 is functionally (directly) connected only to the first locking element 30.
  • the locking element 60 interacts both with the first locking element 30 and with the second locking element 40, that is to say is (directly) functionally connected to them.
  • the second locking element 40 can function in accordance with the first locking element 30, i.e. like the preferred clamping element described above, a single locking element interacting with both clamping elements at the same time in order to simultaneously move them into their respective locking position (and also back into their respective release position) move.
  • the lamp 1 can furthermore have a lamp housing 70 in which at least the swivel joint 4 and preferably the locking elements 30, 40 and particularly preferably the third locking element 50 are provided or received.
  • the lamp arm 3 connected to the swivel joint 4 preferably protrudes from the lamp housing 70.
  • the lamp housing 70 can also accommodate the carrier plate 14.
  • the luminaire housing 70 can also have lighting means (for example LEDs) and / or other electrical and / or electronic components (not shown in detail) for operating the luminaire 1.
  • the lamp housing 70 preferably has a cylindrical shape.
  • a lamp head attachment 71 can be connected to the lamp housing 70, for example by means of appropriate fastening means (screw connection, clip connection or other non-positive and / or positive fastening means).
  • the lamp head attachment 71 preferably has the light emission opening of the lamp head 2.
  • the locking element 60 can be provided in the lamp housing 70 in such a way that it can be operated from outside the lamp housing 70, in particular from a rear side of the lamp housing 70.
  • the lamp housing 70 has a cover part 72 which has the rear side of the lamp housing 70 and in which the locking element 60 is mounted, for example via a through-hole is, so that the locking element 60 is accessible from outside the lamp housing 70 and can therefore be operated.
  • the cover part 71 preferably has a shape which corresponds to that of the lamp housing 70, for example a circular shape.
  • the cover part 71 is connected to the lamp housing 70 preferably via at least one fastening means 72 (screw, etc.), preferably via two fastening means 72.
