The mesh visualization reveals two distinct parts: an outer tan/gold bezel ring (housing) and an inner white/metallic LED emitter disk with a spoke/fan pattern. Segmenting the inner disk from the top view (click at [256, 230]) produced a clean selection of the full emitter surface in all six views, confirmed as distinct from the outer housing by a separate segmentation experiment that isolated the tan ring without selecting the inner emitter. The inner emitter disk is the light-emitting equivalent of the bulb in this recessed LED downlight fixture.",
