Morphology
The meaning 'energy carried by visible light' is directly and compositionally derived from 'luminous' (relating to light or emitting light) + 'energy' (power). This is a literal adjective+noun technical phrase following standard compounding patterns, so a B1 learner who knows both constituents can reasonably infer the meaning.
Etymology
The compound luminous energy joins luminous, meaning 'shining', and energy, meaning 'power', so imagine the power carried by a bright beam of light. That's why it means the 'energy carried by visible light'.
