Abstract:
A lighting system includes a first light source emitting first light rays; a second light source emitting second light rays, a first lens side which refracts the first and second light rays and collimates the refracted light rays; a second lens side which includes a plurality of first lenticules and refracts the first and second light rays; and a third lens side which includes a plurality of second lenticules and refracts the first and second light rays refracted by the second lens side.
