Morphology
The meaning 'a narrow column of light' is directly and transparently derived from combining 'light' (electromagnetic brightness) with 'beam' (a directed shaft or line); 'beam' already denotes a shaft, so the compound straightforwardly refers to that shaft of light. This noun-noun composition is cross-linguistically common (e.g., Spanish 'rayo de luz', French 'rayon de lumière') and would be immediately comprehensible to a B1 learner who knows both words.
Etymology
The noun light beam comes from the image of a straight, strong beam like a wooden bar shining with light. Imagine a narrow bar of light cutting through dark air, and that's why light beam means 'a narrow column of light' today.
