LIGHT SOURCE UNIT, LIGHTING APPARATUS USING THE LIGHT SOURCE UNIT, AND PLANT GROWING EQUIPMENT USING THE LIGHTING APPARATUS
First Claim
1. A light source unit comprising:
- a flat light flux supplying means having a light emitting member, for supplying a light flux that is flat along a predetermined plane and has a predetermined diverging angle; and
a light flux control means for suppressing diffusion of the light flux directed from the flat light flux supplying means, along the aforementioned predetermined plane to form a flat light flux having high directivity.

Abstract
Light emitted from an LED lamp (1) substantially vertically enters the face of the first light diffusion structural member (2) to be diffused within a predetermined plane (P) perpendicular to a longitudinal direction of a linear ridges of the light diffusion structural member (2), and enters the face of the second light diffusion structural member (3) as the flat light flux having a predetermined diverging angle. An incident angle to the second light diffusion structural member (3) varies according to the angle of light, which has passed through the first light diffusion structural member (2). However, light diffusion in the width direction (W) is suppressed by the second light diffusion structural member (3) to be within a range of suitable diffusion angles, and a flat light flux (B) having high directivity is formed.
