Linear light-emitting element, lamp assembly and motor vehicle

Abstract

A linear light-emitting element, having a lateral light exit region and including a core layer which is rod-shaped, at least one end face of the core layer receiving and allowing the entry of light from a light source, a cladding layer which envelops an outer peripheral surface of the core layer, the cladding layer having a smaller refractive index than that of the core layer, and light from the core layer entering the cladding layer by refraction, a transparent light exit layer which envelops an outer peripheral surface of the cladding layer, the transparent light exit layer transmitting light from the cladding layer, and a reflective layer which at least partially covers an outer peripheral surface of the transparent light exit layer, the reflective layer being at least partially opposite a lateral light exit region, reflecting light from the transparent light exit layer towards the lateral light exit region.

Dependencies are inferred from the claim text.
