Abstract:
To provide an illumination device having high efficiency, an illumination method, a video projection apparatus using the same. In order to achieve the object, there is provided an illumination device configured to include a light source and a light condensing body which condenses light from the light source to be emitted, and the light condensing body includes an incidence surface of a light source side, an emission surface emitting light, and a side surface which is present between the incidence surface and the emission surface, the side surface is a curved surface of which a distance from a light axis in a direction orthogonal to the light emitting surface of the light source at the center of the light source becomes large from the incidence surface toward the emission surface and has a plurality of curved-surface-shapes of which shapes of the curved surfaces are different from each other. There is provided an illumination device configured to include a light source, a light integrator homogenizing light emitted from the light source through total internal reflection and filled with a transparent material, a lens converting light emitted from the light integrator into substantially parallel light, and a reflection parabolic surface converting light emitted from the light integrator into substantially parallel light and disposed on the outside of the lens, and a surface of the light integrator side of the lens is disposed on a side closer to a light integrator side than an end in the light axis direction of the lens which is located at a side opposite to the light integrator of the reflection parabolic surface.

Claim (Index 19):
The illumination device according to  claim 18 ,\n wherein respective axes of the rotating bodies are crossed in the light source.
