LED Lighting Fixture
First Claim
1. An LED lighting fixture comprising:
- a set of LED optical units having different light distribution characteristics, respectively, and each of the LED optical units including at least one LED optical module configured to emit light forming a corresponding light distribution characteristic, the at least one LED optical module including an LED serving as a light source and at least one light distribution controlling lens located in an illumination direction of the LED light source, whereinthe at least one LED optical module includes at least one first LED optical module mounted to a first LED optical unit, the at least one first LED optical module configured to form a first light distribution characteristic, and the at least one LED optical module includes at least one second LED optical module mounted to a second LED optical unit, the at least one second LED optical module configured to form a second light distribution characteristic, wherein the first light distribution characteristic and the second light distribution characteristic are different from each other.

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.
