<p>The application concerns a lighting system with an optical device with a cylindrical liquid lens, of the electro wetting type; an emission unit in a position between a vertex and a focus of an elliptical or parabolic mirror. The optical device comprises two layers of apposed cylindrical liquid lenses (11,12), either in parallel or transverse to the lenses of other layer. The liquid lenses are separated fully or partly in one layer from each other by partition walls (35,37). The liquid lenses in one layer may share a liquid (122) with liquid lenses in the other layer.</p> |
