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 16):
An illumination device comprising:\n a light source; and a light condensing body which is formed with a transparent material and is for condensing light from the light source to be emitted, wherein the light condensing body includes an incidence surface of a light source side, an emission surface emitting light, and a side surface present between the incidence surface and the emission surface, and the side surface is a curved surface of which a distance from a light axis in a direction orthogonal to a 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 is configured to have a plurality of curved-surface-shapes of which shapes of the curved surfaces are different from each other, wherein the incidence surface has two shapes in which light emitted from the light source is divided into light of an inner side which is a light axis side and light of an outer side which is away from the light axis in a direction orthogonal with respect to the light axis, wherein the emission surface is configured to have a shape which converts an emission angle of light emitted from the light source and divided into an inner side in the incidence surface, and an outer side of shape is configured with a plurality of different shapes.
