  • ILLUMINATION DEVICE BASED ON LIGHT GUIDE WITH LIGHT SCATTERING PARTICLES AND LIGHT ANGLE SELECTION MODULE
    Publication number: 20150205031
    Abstract: An illumination device (1) is disclosed comprising a light guide (2) with embedded light scattering and/or reflecting particles (5), a first light emitting element (6a), and a second light emitting element (6b). The illumination device (1) is arranged such that for light rays emitted by the first light emitting element (6a), the angles of incidence of the light rays coupled into the light guide (2) are within a first angle interval, and such that for light rays emitted by the second light emitting element (6b), the angles of incidence of the light rays coupled into the light guide (2) are within a second angle interval, wherein the first angle interval and the second angle interval are different. An illumination device (1) is provided in which the amount of light that is out-coupled from the light guide (2) at selected positions can be adapted as desired, for example to give uniform lighting.
