Abstract:
An optical lens, which, after acting upon each light ray emitted from a light-emitting device in which a plurality of light-emitting portions are arranged in an array, emits said light rays, comprising:one or a plurality of a first optical member arrays, each having a plurality of columnar optical members comprising first optical action portions in which a curved surface is formed on either the light incidence side or the light emission side and which act in the X-axis direction on light rays emitted from said light-emitting portions, and in which said columnar optical members are arranged in an array in the same plane; and, a second optical member, formed from a transparent material into a columnar shape, within which said one or plurality of first optical member arrays are embedded in parallel along the column axis direction; and wherein the refractive index of the constituent material of said columnar optical members and the refractive index of said transparent material of said second optical member are different.
