| 摘要 |
The invention relates to a luminous device (1) having a planar light emission characteristic, comprising a planar optical waveguide (2) having at least one light coupling-in surface and having at least one light coupling-out surface (3), and a light source (7) emissive with a first spectral characteristic, wherein the light source (7) is arranged in relation to the optical waveguide (2) in such a way that light emitted from the light source (7) can couple into the optical waveguide (2) via the light coupling-in surface. The optical waveguide comprises a light conversion substance that can be excited by the light from the first light source to emit a secondary radiation. |
