Morphology

arc + lamp

The meaning 'a lamp that emits light by an electric arc' is directly derivable from combining 'arc' (an electric discharge that creates light) and 'lamp' (a light source). This noun–noun compound is compositional and non-idiomatic, so a B1 learner who knows both constituents should readily infer the MWE meaning despite its technical nature.

Etymology

The name arc lamp comes from the bright arc of light that jumps between two rods inside the lamp. That's why arc lamp means a lamp that makes light by an electric arc.
