An LED lighting fixture (34) is provided which achieves effective use of light, uniformly illuminates a large area and, has a high degree of freedom in designing light distribution characteristics. Three types of LED optical modules (1a, 1b, 1c) are used having different light distribution characteristics. Each LED optical module (1) includes an LED light source (14) and a light distribution controlling lens (5) of a different shape which constitute an optical system. Three types of LED optical unit (26a, 26b, 26c) having different light distribution characteristics are used. Each LED optical unit (26a, 26b, 26c) includes a set of LED optical modules (1a, 1b, 1c) having the same light distribution characteristics. The LED lighting fixture (34) is configured to have a combination of the LED optical units (26a, 26b, 26c) having different light distribution characteristics. |
