Morphology

light + up + the + room

The literal composition 'light' (illuminate) + 'up' (increase/activate) + 'room' clearly yields 'illuminate the room,' and the figurative sense 'make a place feel joyful or lively' is a straightforward metaphorical extension of illumination. Because the emotional/figurative meaning follows a common light-as-positivity metaphor (found in many languages) but still requires mapping from physical to affective meaning, a B1 learner who knows the words may guess it in context but would not always derive the full sense without exposure.

Etymology

The idiom light up the room comes from the image of a person who seems to light a room like a lamp when they walk in. So, it means 'to make a place feel joyful, lively, or welcoming'.
