Document Type and Number:
WIPO Patent Application WO/2012/101096
Kind Code:
A3
Abstract:
The lighting device (1) comprises a plurality of light sources (3) which are spaced apart from each other, a reflector (4) for reflecting at least a part of the light (B1, B2, B3) emitted by the light sources (3) and light mixing optics (8) for the spatial mixing of light (B1, B2, B3) emitted into a penumbral shadow area (HS) of the lighting device (1). The light mixing optics (8) is a transparent optics the surface (9) of which comprises at least one light-deflection structure (10, 12a, 12b, 13) designed to deflect incident light (B1, B2, B3) in an at least partially anisotropic fashion.
