Lamp-housing assembly with axially and radially aligned and electrically coupled elements

A lamp-housing assembly for a detector of a sample separation apparatus for separating a fluidic sample, the lamp-housing assembly comprising:

• a lamp seat comprising a lamp-seat accommodation volume;
• a lamp configured to be inserted into the lamp seat;
• and
• a lamp cap configured to be mounted on the lamp seat and on the inserted lamp and comprising a lamp-cap accommodation volume, wherein:
• a lamp seat-sided portion of the lamp is arranged in the lamp-seat accommodation volume, and a lamp cap-sided portion of the lamp is arranged in the lamp-cap accommodation volume;
• the lamp-seat accommodation volume and the lamp-cap accommodation volume are different and separated from each other;
• and
• the lamp-seat accommodation volume is divided into at least two convection-inhibited separated staggered chambers.

A lamp for a detector of a sample separation apparatus for separating a fluidic sample, the lamp comprising:

• a lamp body;
• a first electric terminal and a second electric terminal disposed at axially opposing ends of the lamp body;
• and
• a thermally conductive and electrically insulating flange member arranged on the lamp body, wherein the flange member is configured to enhance an electric isolation of the first electric terminal with respect to the second electric terminal and is further configured to remove heat from the lamp body.
