An object of the present invention is to provide a lighting device capable of properly performing a bounce motion and photography in the event of an unexpected motion. The lighting device of the present invention is a lighting device including a control unit that provides an instruction of an auto-bounce motion. When detecting an auto-bounce motion in S303, the control unit releases the brake of a motor for driving a light-emitting part and performs auto-bounce control in S304. When detecting that the bounce angle of the light-emitting part in the auto-bounce motion reaches a target position and the motor enters a stop period in S303, the control unit automatically switches to the application of an intermittently repeated regenerative brake to the motor. This can suppress a movement of the light-emitting part even in an accidental motion and perform a proper bounce motion with an easy manual operation.

A rotation restricting structure includes a main body a rotator rotatable with respect to the main body, and a rotation restricting member which restricts rotation of the rotator, wherein the rotator includes a rotating plate which rotates with rotation of the rotator with respect to the main body, one of the rotating plate or the main body has a protrusion portion, the rotation restricting member has a contacting portion contactable with the protrusion portion and a rotational shaft which is pivotally supported by the other of the rotating plate or the main body, the protrusion portion contacts the contacting portion by rotation of the rotator, thereby the rotational angle range of the rotator being restricted, and a position of the contacting portion provided on the rotation restricting member is different from a position of the rotational shaft provided on the rotation restricting member.

A flash housing for photographic purposes is disclosed. The flash housing comprises a flash forming element arranged to generate a flash light and a lens element arranged to let at least part of the generated flash light out of the flash housing so as to obtain the flash. The obtainable flash light has a beam lobe with a controllable beam angle. A simulation light generator element is arranged for simulation of the obtainable flash light beam lobe having the controllable beam angle.

A drive unit changes an irradiation direction of irradiation light from a light-emitting portion. A setting unit sets the irradiation direction of the irradiation light from the light-emitting portion. A control unit controls the drive unit. Depending on a cause of which the irradiation direction of the irradiation light from the light-emitting portion changes from the irradiation direction that is set by the setting unit, the control unit changes responsiveness of the drive unit that changes the irradiation direction of the irradiation light from the light-emitting portion into the irradiation direction that is set by the setting unit.

An illumination device includes a first housing, a second housing having a light source, capable of rotating with respect to the first housing, a driving unit configured to rotate the second housing about a first axis in a first direction and/or a second axis orthogonal to the first axis in a second direction, with respect to the first housing, and a display control unit configured to display, on a display unit, information indicating an irradiation direction of light from the light source, wherein the display control unit changes information about the first direction included in the information indicating the irradiation direction displayed on the display unit, according to a rotation angle of the second housing in the second direction.

A system for electronic patient care includes a hub. The hub is configured to monitor a patient-care device. The sandbox may be configured to control access to at least one of a hardware resource and a software resource. The hub is further configured to identify the patient-care device and execute an application to monitor the patient-care device. The hub executes the application within the sandbox component such that the application accesses the at least one of the hardware resource and the software resource through the sandbox component. The hub may be further configured to control the patient-care device. The hub may be further configured to receive an identification from the patient-care device and download the application from a server associated with the identification. The hub may be further configured to receive an identification from the patient-care device and update the application from a server associated with the identification.

To increase the accuracy of adjusting the main light emission. An amount of main light emission is adjusted on the basis of an estimated pre-light-emitted subject distance or information corresponding to the estimated pre-light-emitted subject distance and an estimated lens-focused subject distance. The estimated pre-light-emitted subject distance and the information corresponding to the estimated pre-light-emitted subject distance are obtained by pre-light-emission processing. The estimated lens-focused subject distance is obtained from focus information through a lens. In a case of bounce light emission, in a case where the estimated pre-light-emitted subject distance is smaller than the estimated lens-focused subject distance, a distance made closer to the estimated lens-focused subject distance from the estimated pre-light-emitted subject distance by a predetermined amount is set as an estimated subject distance for adjusting the main light emission.

A machine-vision device including a camera system, with a camera and an integrated origin light source that is integrated into the camera system, and a lighting device with: control interface including: a plurality of light sensors each for capturing a respective origin light signal, and emitting a respective sensor signal, and an electronic unit for processing the sensor signal configured so as to transmit a respective control signal to a respective output of the processing electronic unit. The lighting device with one or more automatically controlled light sources that are external to the camera system, each connected to one respective output of the processing electronic unit by respective connection, so as to be controlled with the control signal delivered to the output. At least one light sensor is placed so as to directly capture the light emitted by one origin light source.

A technique that prevents a movable unit of a strobe device including a light emission section from unexpectedly interfering with an obstacle during rotation thereof. The movable unit is supported in a manner rotatable with respect to a device body about a first axis in a vertical direction, and rotatable about a second axis in a lateral direction. In bounce flash shooting, the movable unit irradiates light from the light emission section toward a ceiling to cause reflected light from the ceiling to be irradiated to an object. The movable unit is rotated such that the light emission section is oriented in the optimum irradiating direction. Whether to drive the movable unit in the lateral direction is determined based on a result of determining whether a rotational angle of the movable unit driven in the vertical direction exceeds a predetermined angle.

A control method for an illuminating device, which is mounted on an aircraft having an image acquisition apparatus, includes obtaining attitude data of an image acquisition apparatus and rotating the illumination device, according to the attitude data of the image acquisition apparatus, to match an illumination area of the illumination device with a photographing area of the image acquisition apparatus.
