Classification: CPC G  F | IPC F

Claim 0:
1. A light diffuser to receive first light and emit scattered light, the light diffuser comprising:
an incident surface to receive the first light;
a first light scattering portion including light scattering particles present in a medium, the first light scattering portion generating the scattered light by guiding the received first light and scattering the received first light with the light scattering particles; and
an emission surface to emit the scattered light,
wherein a concentration of the light scattering particles in the light diffuser is distributed such that the concentration increases non-linearly and discontinuously with distance from an incident edge in a light guiding direction of the first light,
wherein the light scattering particles are distributed to increase exponentially with the distance, and
wherein the light scattering particles are distributed to increase according to a fractional function.
