Morphology

light + up + a + room

The combination 'light' + 'up' clearly yields the literal sense 'to illuminate,' and the figurative meaning of making someone or the mood 'brighter' is a straightforward metaphorical extension of illumination. This metaphor is common across languages so learners may guess a positive/mood-related sense, but because it involves a non-literal transfer from physical light to emotional effect it is not fully predictable without exposure.

Etymology

Light up a room comes from the simple picture of a lamp that turns on and fills a dark room with light. When someone smiles or brings joy they seem to light the room, so the phrase means 'to bring happiness or energy' to others.
