Abstract
The illumination apparatus includes a light source, a first reflective portion provided inside further than the light source in a radial direction so as to extend in a circumferential direction and reflecting light from the light source toward a light projecting direction. The apparatus further includes a second reflective portion provided inside further than the light source in the radial direction so as to extend in the radial direction and reflecting the light from the light source toward an area extending to a side away from the light source in the circumferential direction.
Claims20
An illumination apparatus, which is arrangeable so as to surround an image capturing lens, the apparatus comprising:
- when, in a state where the illumination apparatus is arranged so as to surround the image capturing lens, a direction corresponding to a radial direction of the image capturing lens is defined as a radial direction of the illumination apparatus, a direction surrounding the image capturing lens is defined as a circumferential direction of the illumination apparatus, and a direction toward an object field to be captured through the image capturing lens is defined as a light projecting direction of the illumination apparatus,
- a light source;
- a first reflective portion provided inside further than the light source in the radial direction so as to extend in the circumferential direction and reflecting light from the light source toward the light projecting direction;
- and
- a second reflective portion provided inside further than the light source in the radial direction so as to extend in the radial direction and reflecting the light from the light source toward an area extending to a side away from the light source in the circumferential direction.
An illumination apparatus comprising:
- a first reflective portion formed to have an arc shape;
- a light source arranged outside further than the first reflective portion in a radial direction of the first reflective portion;
- a second reflective portion reflecting light from the light source to a side away from the light source in a circumferential direction of the first reflective portion;
- and
- an exit portion where the light reflected by the first reflective portion exits,
- wherein the first reflective portion reflects the light from the light source and the light from the second reflective portion toward the exit portion.
