Abstract
A leaf-filtered sunlight simulation control device includes a plurality of light sources, a single lens, and a leaf-filtered sunlight light source control module to control positions of the plurality of light sources. The leaf-filtered sunlight light source control module controls the positions of the plurality of light sources so that F<A is satisfied, where F is a focal length of the lens and A is a distance from a center axis of the lens to each of the light sources.
Claims10
A leaf-filtered sunlight simulation control device comprising:
- a single lens;
- a plurality of light sources arranged in parallel with a center axis, the center axis being orthogonal to an optical axis of the lens;
- and
- leaf-filtered sunlight light source control circuitry to control positions of the plurality of light sources, wherein
- the leaf-filtered sunlight light source control circuitry controls the positions of the plurality of light sources to satisfy F<A,
- where F is a focal length of the lens and A is a distance from the center axis to each of the light sources.
