Abstract: An illumination apparatus includes a light source, a light-receiving unit, and a light guide unit formed in an arc shape. The light guide unit includes a light incidence section on which light from the light source is incident. The light incidence section is disposed on an outer circumferential side of the light guide unit, and faces the light source. The light guide unit further includes a first reflecting section having a first and a second region, and a second reflecting section having first and second surfaces. The first surface reflects the light incident from the light incidence section toward the first region, and the second surface reflects the light incident from the light incidence section toward the second region. The light-receiving unit is disposed at a position between the first and the second surfaces.

The illumination device includes a first light source, a second light source, a main capacitor configured to store electric charge for causing the first light source and the second light source to emit light, a first coil electrically connected between the first light source and the main capacitor, and a second coil electrically connected between the second light source and the main capacitor. A radial direction of the first coil and a radial direction of the second coil are parallel to a vertical direction of the illumination device, the first coil and the second coil are aligned with the main capacitor in a horizontal direction of the illumination device, and the first coil is aligned with the second coil in a direction orthogonal to the horizontal direction of the illumination device.

Abstract: An illumination apparatus includes a main body, a movable unit, a first driving unit, a second driving unit, and a control unit. The movable unit is rotatable with respect to the main body and includes a light emitting unit and an optical member disposed in front of the light emitting unit to refract incident light. The first driving unit rotates the movable unit with respect to the main body. The second driving unit moves at least one of the light emitting unit and the optical member to change relative positions. Power is supplied to the second driving unit from a power source that supplies power to the first driving unit. The control unit controls a rotation operation performed using the first driving unit and a moving operation performed using the second driving unit so that the rotation operation is performed after the moving operation is performed.

Abstract: Light emission control makes it possible to determine an appropriate main light emission amount even when an optical accessory that changes color characteristics of transmitted light is attached forward of a light emission section of an illumination device. A strobe capable of having a color filter attached thereto, which changes color characteristics of transmitted light. The strobe includes a strobe microcomputer that acquires information on characteristics of the color filter attached forward of the light emission section, and transmits the acquired information on the characteristics to an image pickup apparatus on which the strobe is mounted.

Abstract: A camera accessory device which not only makes it possible to prevent a camera-side accessory shoe from being scratched thereby, but also encores positive electrical connection between the camera accessory device and a camera. The camera accessory device comprises a lock lever, a shoe bracket for engagement with the camera-side accessory shoe, contact pins for contact with respective electric contacts of the camera-side accessory shoe, a contact spring-holding member, and an accessory shoe-holding member which moves, in accordance with rotation of the lock lever, to a shoe member-locking position or to a shoe member-unlocking position. The contact pins are urged by the holding members such that urging forces applied to the electric contacts become larger when the accessory shoe-holding member has moved to the shoe member locking position than when the same has moved to the shoe member unlocking position.
