High-pressure discharge lamp

A high-pressure discharge lamp as motor car head lamp having a ceramic discharge vessel is proposed, which lamp is compact and has a relative simple construction.

The discharge vessel is positioned in the outer tube, and held at both ends by 2 expansion joints. These expansion joints are fixed to the feed-troughs, which are embedded in sealing disks. These disks are fritted to the outer tube to make a gas tight sealing. The disks can be shifted before fixing, to align the discharge vessel with the outer tube.

A model is shown in the figure.

The thus formed lamp has a relative low labour content.
