Morphology

luminous + flux + unit

The phrase is directly compositional: 'luminous' (relating to light) + 'flux' (rate or flow of energy/quantity) + 'unit' (a measurement standard) combine to mean a measurement unit for luminous flux. This follows standard noun–noun technical composition and is cross-linguistically transparent, so a B1 learner who knows the constituents should be able to infer the meaning.

Etymology

Luminous flux unit comes from a simple image: luminous means light, flux means flow, and unit is a measure. Imagine light like water flowing and the unit counts how much light flows, so it means 'a unit used to measure how bright a light looks'.
