Abstract

An optical lens () capable of facilitating efficient light distribution control with a simple configuration is provided. It comprises a plurality of light distribution control parts () continuing in a bilateral direction such that each of the light distribution control parts corresponds to each column of LEDs (), the light distribution control parts defining optical paths of light from the LEDs () on a column basis, one light distribution control part () discharges light entering from the LEDs () in a column corresponding thereto in one direction of the bilateral direction that intersects the optical axes, and a further light distribution control part () discharges light entering from the LEDs () in a column corresponding thereto in a further direction of the bilateral direction that intersects the optical axes.
