Patent ID: 7648256

Claim:
A lighting system comprising: a first light source emitting first light rays; a second light source having a light emitting point partly displaced from the first light source and emitting second light rays whose wavelength differs from a wavelength of the first light rays; a first lens including a first lens side facing the first and second light sources, and a second lens side being opposite to the first lens side, the first lens side which refracts and collimates the first and second light rays, the second lens side which includes a plurality of juxtaposed first lenticules and refracts the first and second light rays collimated by the first lens side; and a second lens including a third lens side facing the second lens side, the third lens side which includes a plurality of juxtaposed second lenticules and refracts the first and second light rays refracted by the second lens side, wherein each of the first lenticules has a convex surface curved outward toward the third lens side; each of the second lenticules has a convex surface curved outward toward the second lens side; each of the second lenticules correspond to each of the first lenticules on a one-to-one basis; the first lenticules collect the first and second light rays on the corresponding second lenticules, respectively; and a part of a first illumination area of the first and second light rays refracted by one of the first lenticules and one of the second lenticules overlaps with a part of a second illumination area of the first and second light rays refracted by another one of the first lenticules and another one of the second lenticules.
