Definitions

  • the present invention relates to a lamp with two housing parts that can be rotated relative to one another about an axis of rotation and a stop for limiting the rotational movement of the housing parts.
  • one of the housing parts is provided for mounting the luminaire on a surface (e.g. wall or ceiling).
  • the other housing part usually carries the illuminant, which, due to the rotatable arrangement with respect to the fixed housing part, can be rotated around the defined axis of rotation and can thus be aligned as desired over the specified rotation angle range.
  • a lamp usually has a (rotary) stop.
  • This usually has two stop partners, which work equally with one another in both directions of rotation, in that they come into contact with one another after almost one complete revolution in order to limit the rotational movement of the housing parts with respect to one another.
  • one of the stop partners of the stop is usually provided on the permanently mounted housing part and the other stop partner is provided on the housing part rotatable relative thereto in such a way that the stop limits the rotation of the lamp after an essentially almost complete rotation.
  • the area of application of the lamp is limited to below 360 °, usually around 350 ° to 355 °.
  • the reason for this is the width of the mutually corresponding stop partners, which, due to their given width in the direction of rotation, do not allow a complete 360 ° rotation.
  • Luminaires with housing parts that can be rotated relative to one another are known from WO 2011/019945 A1 , EP 2 757 308 A1 , US 2009/213595 A1 , EP 1 174 307 A2 and EP0508142 A2 .
  • the present invention relates to a lamp with a first housing part and a second housing part, which can be rotated relative to one another about an axis of rotation.
  • the luminaire also has a stop which is designed in such a way that the housing parts can rotate relative to one another in both opposite directions of rotation of the housing parts around the axis of rotation (or an angle of rotation of the housing parts).
  • the stop has a first stop part, which is connected to the first housing part, and a second stop part, which is connected to the second housing part.
  • the stop parts are designed in such a way that they interact to limit the rotary movement in each direction of rotation, preferably cooperate at a stop point.
  • At least one of the stop parts is designed to be flexible in such a way that this flexible stop part (11) is deformed when the two stop parts (11, 21) interact by rotating the housing parts (10, 20) relative to one another, so that the stop is at least seen in the direction of rotation can be offset.
  • a "stop point” is understood to mean the point of point, line or surface contact between the stop partners - that is, the stop parts - during the effective contact of the two to limit the rotational movement or the rotational angle.
  • a lamp with such a stop By means of a lamp with such a stop it is made possible that two housing parts which can be rotated relative to one another are limited in their rotational movement on the one hand, while at the same time a deformation of at least one of the stop parts caused by the interaction of the stop parts while maintaining the rotation angle-limiting effect of the stop parts is in turn a comparison to conventional fixed stops increased angle of rotation of the housing parts relative to each other.
  • a lamp can be provided with a corresponding stop which, for example, enables a complete 360 ° rotation of the housing parts relative to one another.
  • the stop thus offers an enlarged range of the angle of rotation with at the same time reliable rotation limitation in comparison to comparable lights with a rigid fixed stop, as is known from the prior art. Thanks to its flexible design, the stop can also be optimally adapted to the given conditions.
  • the stop parts are designed in such a way that they interact to limit the rotational movement in each direction of rotation at a stop point, the at least one stop part being so flexible that the stop point, viewed against the direction of rotation of the housing part having this stop part, is seen with respect to this housing part by deformation of the at least one stop part is relocatable. Due to the safe offset of the stop point, a safe installation in a defined point, as previously defined, can be made possible over the entire effective range of the stop.
  • the stop parts are preferably located in a movement path of the respective other stop part when the housing parts are rotated relative to each other. This enables a direct interaction of the stop parts, which in turn results in a simplification of the structure of the lamp.
  • the at least one stop part can be provided pivotably so that when the two stop parts interact by rotating the housing parts relative to one another, the at least one stop part is flexibly pivoted, preferably the stop point is offset by deformation of the at least one stop part.
  • the pivotable stop part can have a film hinge via which it is flexibly connected to the associated housing part.
  • the flexible stop part can maintain its flexibility as a result of the material, for example by manufacturing it from a flexible or elastic material, and / or due to its geometry, for example through an area of small material thickness.
  • the flexible stop part can be an element made of a flexible or elastic material, which is located, for example, in the path of movement of the other stop part when the housing parts are rotated relative to each other.
  • an elastic block is conceivable here, which is located in the movement path of the other stop element and thus can be elastically deformed on both sides by the other stop element in such a way as to increase a rotational angle range of the housing parts relative to one another in comparison to a block or stop part made of a rigid material.
  • One of the stop parts can be designed to be flexible - as described above for the at least one stop part - while the other stop part is designed to be rigid.
  • both stop parts are designed to be flexible and thus both stop parts are designed as the flexible stop part described above.
  • the desired offset of the stop point can be set in any way using both stop parts.
  • the stop can be designed to increase an angle of rotation of the housing parts relative to each other by the amount of the deformation-related offset of the flexible stop part in the direction of rotation, preferably by the amount of the offset of the stop point in the respective direction of rotation.
  • An increase in the angle of rotation of the housing parts relative to one another per direction of rotation can preferably be from 1 ° to 20 °, more preferably from 2 ° to 10 °, and particularly preferably from 2.5 ° to 5 °. In this way, a defined increase in the angle of rotation can be achieved by means of the stop. This is preferably chosen such that it compensates for at least the width of the stop.
  • the stop is preferably designed in such a way that the housing parts can be rotated relative to one another around the axis of rotation by (a rotation angle of) at least 360 ° due to the deformation of the flexible stop part or the offset of the stop point.
  • a rotation angle of at least 360 ° due to the deformation of the flexible stop part or the offset of the stop point.
  • the stop parts preferably have a defined width, the amount of the deformation-related offset of the flexible stop part seen in the direction of rotation, preferably the amount of the offset of the stop point, seen in the respective direction of rotation at least a part and particularly preferably at least the entire width of the stop parts compensates.
  • the amount of offset of the stop point or the amount of movement or (elastic) deformation is preferably at least half the sum of the width of the first and second stop parts. In this way, viewed in both directions of rotation, the width of the stop part can at best be completely compensated and thus, for example, a complete 360 ° rotation can be made possible, while the stop remains equally effective.
  • the stop parts viewed in the direction of rotation, each have a width between 0.2 and 20 mm, more preferably between 0.5 and 10 mm.
  • the present invention can thus be used equally for both comparatively wide and narrow stop parts.
  • the stop parts preferably have two stop areas offset from one another when viewed in the direction of rotation, which are designed such that, depending on the direction of rotation, they interact with the facing stop area of the other stop part, preferably to form the stop point.
  • a stop part can serve in both directions of rotation in the case of a substantially 360 ° rotation to the stop, so that the complexity of the lamp or the stop can be designed to be significantly reduced overall.
  • the at least one stop part can have a preferably rigid stop head for interacting with the other stop part to limit the rotary movement. Furthermore, the at least one stop part can furthermore have a flexible stop arm which connects the stop head to the associated housing part and is also designed in such a way that it enables the flexible stop part to be deformed, preferably the offset of the stop part or the stop point at least in the direction of rotation D1, D2 seen. In this way, a particularly simple configuration of a corresponding stop of a lamp according to the invention can be provided and the same can be manufactured particularly easily.
  • the at least one stop part preferably its stop head over its stop arm, can be positioned between two opposite ones as seen in the direction of rotation defined stop positions be flexibly movable. In this way, a stop can be provided which makes it possible to provide a defined stop relative to one another in both directions of rotation independently of the direction of rotation of the two housing parts.
  • the at least one stop part can furthermore have two stop elements which are spaced apart from one another as seen in the direction of rotation and which form the defined stop positions.
  • the stop positions are thus provided by preferably simple structural stoppers in order to provide the stop positions in a defined manner.
  • the at least one stop part preferably its stop head over its stop arm, can be flexibly movable between the two stop positions in such a way that the flexible stop part when interacting with the other stop part depends on the direction of rotation and when the flexible stop part is deformed, preferably the flexible stop arm and in particular when Offset of the stop point with which one of the stop elements can come into contact to limit the rotary movement. In this way, the stop can be safely brought into engagement, while after the maximum offset of the stop part or the stop point, a defined rotational movement or rotational angle limitation can be reliably provided.
  • the first stop part is preferably formed integrally with the first housing part.
  • the second stop part can also be formed integrally with the second housing part.

  • the stop is preferably designed in such a way that a limiting force of the stop for limiting the rotational movement does not or only slightly increases with increasing deformation or with increasing displacement of the flexible stop part, preferably with increasing displacement of the stop point.
  • the stop therefore does not act (strongly) against the rotary movement and does not push the housing parts again in the opposite direction after the rotary movement has ended.
  • the said limiting force increases with increasing deformation or increasing offset. This can then be the case if no defined stop positions or stop elements are provided.
  • a maximum stop can be set, for example, depending on the material or through the geometric design of the stop parts, while at the same time it causes a reliable rotation limitation even with increasing rotation angle in order to hold the housing parts securely by means of the stop.
