Luminous body
First Claim
1. A luminous body comprising:
- a housing with a light emission surface and a plurality of light sources arranged in the housing, wherein the housing comprises;
at least a first optical medium with a first optical scattering power, into which medium the light of the light sources is coupled; and
a plurality of second optical medium elements with a second optical scattering power disposed in the housing, wherein each of the second optical medium elements comprises a plurality of particles, and each of the second medium elements is disposed over a respective one of the light sources.

Abstract
A luminous body is described, in particular in the form of a planar lighting device for general lighting or for back-lighting of displays, which luminous body comprises a plurality of light sources (2), for example LED elements, arranged in a housing (10), in particular an optical waveguide plate (1). The optical waveguide plate (1) forms a first optical medium (1) with a first optical scattering power, into which the light of the light sources (2) is coupled. Furthermore, at least one second optical medium (5) with a second optical scattering power is provided, such that the light propagating in the second optical medium (5) is at least substantially coupled in from the first optical medium (1), and the scattering power of at least one of the media is chosen for the purpose of influencing the flow of light in the housing (10) such that a given brightness distribution of the light on the light emission surface (4) is achieved.
