Morphology
The phrase is a straightforward adjective + noun composition: 'ultraviolet' names a type of radiation and 'source' denotes an origin or emitter, so the combined meaning 'an object that emits ultraviolet radiation' is directly derivable. This is a regular, compositional pattern found across languages, so a B1 learner who knows both words would readily infer the MWE's meaning.
Etymology
Ultraviolet source comes from the idea of light 'beyond violet' in a rainbow. People found a strange, invisible light just past the violet color, so a lamp or object that makes that light was called an ultraviolet source. That's why today it means a device that gives off ultraviolet light.
