Morphology

luminous + intensity + unit

The phrase is compositionally transparent: 'luminous' (relating to light) + 'intensity' (strength/amount) + 'unit' (measurement standard) clearly yields a measurement for the amount/strength of light. Although it's a technical term, the constituent meanings combine in a straightforward noun-noun compound pattern that a B1 learner who knows the individual words can infer.

Etymology

Luminous intensity unit may come from the old practice of using a single candle as the standard of light: a candle's flame was an easy way to compare lights. The words luminous ('light'), intensity ('brightness') and unit ('one measure') explain why it now means 'a standard measure of how much light goes in one direction'.
