Morphology

light + upon

The sense 'to discover by chance' is partially derivable because 'light' here uses the archaic/poetic sense 'to alight/land' and with 'upon' implies landing on or encountering something. However, that verbal sense of 'light' and the preposition 'upon' are relatively rare/archaic, so a B1 learner who only knows the common senses may not reliably predict the idiomatic meaning.

Etymology

The phrasal verb light upon comes from the image of a beam of light suddenly falling upon an object and making it visible. That's why light upon means 'to discover or find something by chance'.
