摘要:
A light-emitting device comprising a solid-state light source (3), at least one conversion element (4) and a light-scattering element (6), wherein the solid-state light source (3) is provided to emit a first part (511) of a primary radiation for entry into the light-scattering element (6) and a second part (512) of a primary radiation for entry into the conversion element (4) for at least partial conversion into at least one secondary radiation (521, 522), the light-scattering element (6) is provided to generate a mixed radiation (5) having a Lambertian light distribution pattern from the first part (511) of the primary radiation, the secondary radiation (521, 522) and a portion of the second part (512) of the primary radiation that has not been converted in the conversion element (4), and the first part (511) of the primary radiation leaves the light-emitting device without having passed the conversion element (4).
