Abstract
A light source device for a fiber optic illumination system comprises a solid-state light emitting element having an emission surface shaped in quadrate, a light collection lens system with a positive power comprising at least a plano-convex lens, and a reflection member having a cylindrical reflection surface therein, all of which are arranged in this order coaxially with one another along a principal axis passing a center of the light emitting element, wherein the plano-convex lens is placed with a plane surface thereof directly facing and located at a space distance apart from the emission surface so as to form a virtual image of the emission surface.
Claims4
A light source device for an illumination system having a light guide means, said light source device comprising:
- a solid-state light emitting element capable of emitting its light from an emission surface which is shaped in quadrate and has a principal axis at an axial thereof;
- a light collection lens system having a positive power which includes at least a plano-convex lens and is arranged coaxially with said solid-state light emitting element along said principal axis;
- and
- a reflection member having a cylindrical reflection surface therein, said reflection member being arranged coaxially with side said solid-state light emitting element along said principal axis on a side opposite to said solid-state light emitting element with respect to said light collective lens system;
- wherein said plano-convex lens is placed with a plane surface thereof directly facing and located at a space distance apart from said emission surface so as to form a virtual image of said emission surface.
