Abstract
A thin-film LED (10, 20, 30) mounted on a substrate (5) and with a defined upper surface (2) approximately hemispherically emitting light, with the upper surface (2) being diffusively transmissive, a lower first layer of identically defined linear prismatic film (31) separated from the upper surface (2), a upper second layer of linear prismatic film (32), identical to but oriented orthogonally to the layer (31), and a circumferential vertical reflective wall (24) bordering on both of the first (31) and second layer (32) and extending height from the substrate (5) to the top of the second layer (32)
