triangular prism desk lamp 3d model

A revolutionary luxury desk lamp built around optical refraction as its core design and functional principle. A solid equilateral triangular prism of optical borosilicate glass 10cm per side sits at the apex of the lamp, mounted on a frictionless rotating platform allowing 360-degree manual rotation. A focused warm white LED beam 5700K enters one face of the prism and exits as a continuous visible light spectrum projected outward, casting a rainbow of refracted light across desk and wall surfaces that shifts and rotates as the prism turns. The prism is held by two ultra-thin titanium rods 2mm diameter forming a minimal open cradle. The entire assembly sits on a single slender hollow stem of brushed steel 8mm diameter 52cm tall routing all wiring internally. Base is a flat rectangular slab of polished white Carrara marble 24cm long 10cm wide 2cm thick, flush rear cable exit, touch dimmer on marble surface. Single object, white background, photorealistic PBR, ultra detail.
