Definitions

  • the invention relates to a lamp, in particular an outdoor lamp, which has a device for attachment to a lamp post, which allows to position the lamp relative to the mast in different inclinations.
  • a mast mounting which allows a lamp head to pivot relative to the mast, can be carried out.
  • an outdoor lamp with a device for mast fixing which also allows adjusting the angle of inclination relative to the horizontal.
  • the adjustment mechanism has been integrated into the luminaire housing. He provides a curved mounting flange, which has slots through which the lamp housing can be fixed in different angular positions by means of screws.
  • the adjustment mechanism only allows a pivoting of the lamp by a few degrees. The adjustment range can not be increased because the contact surface on the lamp housing, in which the flange is screwed, includes only a short circular section, which is determined by the shape of the housing.
  • the attachment mechanism is based on a frictional engagement between the attachment flange and the luminaire housing. So that the frictional connection can safely carry even heavy luminaire housing, high clamping forces must be applied by a correspondingly high number of screw connections between the mounting flange and the housing.
  • Object of the present invention is to provide a lamp with adjustable mast attachment available, which allows a large adjustment range and safe handling.
  • a lamp in particular an outdoor lamp, which is adapted for mounting on a mast

  • the determination of the bearing element in the housing or a component connected to the mast is effected by a positive connection, which can be formed in a plurality of angular positions.
  • a positive connection is suitable for holding heavy lights without the need for very strong clamping forces, as they are necessary to form a conclusion.
  • the receiving space for the bearing element is integrated into the housing or a mast stoolen component, so that both the design and the functionality advantages over mast fastenings are given, which have an exposed hinge point.
  • a clamping device which is adapted to fix the positive connection between the bearing element and the receiving space in the housing in one of the selected angular positions.

  • a screw thread has the advantage that much higher clamping forces can be applied by a high torque.
  • a combination between a spring and a screw mechanism is also provided as a clamping device. In this case, by increasing the torque on the screw thread, the spring can be compressed, so that the clamping force applied to the parts to be engaged by the spring is increased. To release the clamping device, the screw connection can be loosened counter to the spring force until the clamping force has been reduced to such an extent that rotation of the lamp housing relative to the bearing element in the receiving space is possible.
