Morphology
The meaning 'a device or object that emits light' is directly and compositionally derivable from combining 'light' (illumination) with 'source' (origin). This noun–noun composition is a common, literal pattern in English and has clear parallels in many languages (e.g. Spanish 'fuente de luz'), so a B1 learner who knows both constituents will readily understand it.
Etymology
Light source comes from a simple image: the light coming from a source like the sun or a lamp. So, it means 'a thing that gives light', for example a bulb or a candle used to light a room.
