OPTICAL SYSTEM FOR GENERATING COMPOSITE LIGHT BEAM HAVING WIDE APERTURE ANGLE

Title:

OPTICAL SYSTEM FOR GENERATING COMPOSITE LIGHT BEAM HAVING WIDE APERTURE ANGLE

Document Type and Number:

Japanese Patent JP2012216542

Kind Code:

A

Abstract:

To provide an optical system capable of widening an aperture angle of the composite light beam at the outlet of light modules.

The optical system 14 generates composite light beams along an optical axis X from a light source 12. The composite light beams include at least one center light beam and at least one peripheral light beam surrounding the center light beam, and are directed toward a light diffuser for re-distributing the composite light beams by a prescribed method on a plane orthogonal to the optical axis X. The optical system generates the center light beams and/or the peripheral light beams on a second plane including the optical axis X, and beams 16.1, 16.2, 17.1, 17.2 of the center light beams and/or the peripheral light beams are constructed so as to be inclined to the optical axis X on the both sides of the optical axis X to form the center light beams and/or the peripheral light beams.
