Abstract
An LED lighting fixture 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 are used each having different light distribution characteristics. Each LED optical module includes an LED light source and a light distribution controlling lens of a different shape which constitute an optical system. Three types of LED optical units having different light distribution characteristics can be used. Each LED optical unit includes a set of LED optical modules having the same light distribution characteristics. The LED lighting fixture is configured to have a combination of the LED optical units having different light distribution characteristics.
