Patient lamps (wall)

Patient lamps are found, for example, in medical practices or by hospital beds. The fitting and wiring for these rotating, swivelling lamps are usually based on slip rings.

Detailed application description

Description of problem:

Patient lamps used in treatment and care facilities are characterised by high functionality and mobility and are often wall-mounted. In contrast to support arm lamps in operating theatres, design is also a criterion. However, a slimmer, more elegant design simultaneously means less space is available for installing the slip rings.

The slip rings have three electrical contacts for light. It must be possible to rotate them in all directions and they should additionally be small and pluggable. A patient lamp mounted on a wall bracket requires a total of three slip rings connected in series. The electrical specification is 5 A at 48 V DC.

Description of solution:

Cantilever mechanisms, spring arms and/or rotary joints are often used to mount patient lamps to the wall. In order to meet flexibility and functionality requirements despite the slimmer component design, 澳门新莆京网络平台 relies on its proven SA030 slip ring rotary joint with triple pole design. The rotary plug has a diameter of just 30 mm. Silver-plated punched bending parts, which are rated for 15 A at 48 V DC, were chosen for the load contacts. The contacts of the slip ring rotary joint have a graded diameter and radial spring mounting, allowing them to be separated or securely mated and turned in the axial direction. This simplifies the installation procedure: if the plug and socket are installed in the predetermined position, the mechanical parts and electrical connection can be assembled blind.
