Abstract
A lighting device includes a semi-rigid arm having a tubular shape and an arm cavity, and proximal and distal ends, which can be brought into various positions, a lighting head which is attached to the distal end of the arm and supported by the arm, a support body with a receptacle cavity which accommodates the proximal end of the arm to support the arm, and an inner support sleeve which is disposed at the proximal end of the arm at least partially in the arm cavity.
Claims29
A lighting device, comprising:
- a semi-rigid arm configured to be brought into various positions in all directions, the arm having a tubular shape and an arm cavity, and proximal and distal ends;
- a lighting head which is attached to the distal end of the arm and supported by the arm;
- a support body having a receptacle cavity configured to accommodate the proximal end of the arm to support the arm;
- an inner support sleeve which is disposed at the proximal end of the arm at least partially in the arm cavity, wherein the portion of the inner support sleeve at least partially disposed in the arm is disposed in the arm cavity with a radial clearance of less than 1 millimeter;
- and
- a supply cable that extends through the inner support sleeve to the lighting head.
A trunk element, comprising:
- a flexible semi-rigid tubular body with a tubular cavity;
- a receptacle body with a receptacle cavity which accommodates one end of the tubular body;
- and
- an inner support sleeve which is arranged at an end of and at least partially within the tubular body, the support sleeve including a central opening configured to allow passage of a supply cable through the support sleeve, wherein the inner support sleeve is made of metal.
A support sleeve for a lighting device, the lighting device including a semi-rigid arm configured to be brought into various positions in all directions, the arm having a tubular shape and an arm cavity, and proximal and distal ends, and a lighting head which is attached to the distal end of the arm and supported by the arm, and a support body having a receptacle cavity configured to accommodate the proximal end of the arm to support the arm,
- the support sleeve configured to be inserted into the arm cavity of the semi-rigid arm of the tubular shape, the support sleeve including a central opening that allows passage of a supply cable through the support sleeve, wherein the supply cable comprises a strain relief element, and wherein the inner support sleeve has a support sleeve inner projection which functions as an abutment for the strain relief element of the supply cable when a tensile force is exerted on the supply cable in the proximal direction.
A lighting device, comprising:
- a semi-rigid arm configured to be brought into various positions in all directions, the arm having a tubular shape and an arm cavity, and proximal and distal ends;
- a lighting head which is attached to the distal end of the arm and supported by the arm;
- a support body having a receptacle cavity configured to accommodate the proximal end of the arm to support the arm, wherein the arm has an arm inner surface facing the arm cavity and an opposite arm outer surface, and wherein the receptacle cavity of the support body has a radial receptacle cavity inner surface which is at least one of radially clamped and glued to the arm outer surface in an area of the proximal end of the arm;
- an inner support sleeve which is disposed at the proximal end of the arm at least partially in the arm cavity;
- and
- a supply cable that extends through the inner support sleeve to the lighting head.
