Morphology

luminance + unit

The meaning is directly compositional: 'luminance' (brightness) combined with 'unit' (a measure) yields 'a unit for measuring luminance,' so the sense can be derived from the parts. The noun–noun measurement pattern is standard and cross-linguistically common, so a B1 learner who knows both constituents should understand the MWE.

Etymology

The term luminance unit comes from the words luminance (the amount of light a surface sends to our eyes) and unit (one fixed measure). Imagine measuring how bright one small square of a screen is; that standard number is the 'luminance unit', which is why the phrase means 'a measure of brightness'.
