LIGHTING SYSTEM

摘要

The invention relates to a lighting system comprising: - a light source to emit light; - a transparent first optical element comprising at least one bounded space filled with blue phase mode liquid crystal material, wherein at least a part of the emitted light successively passes a first boundary surface and a second boundary surface of the bounded space, said first boundary surface being unparallel to said second boundary surface; and - electric means to apply an electric field to the bounded space substantially parallel to a direction of the emitted light incident on the first boundary surface of the at least one bounded space.
