Abstract
A lighting device that is capable of retracting a reflective member inside a lighting device and of deciding size of the reflective member irrespective of the size of the lighting device. The lighting device includes a light emitting section and a reflective member. The reflective member is drawably retracted in the light emitting section and is provided with reflectors that are developed by a drawing operation to reflect a part of light irradiated from the light emitting section. Area of the reflectors in a developed state is more than area of the reflectors in a retracted state.
Claims10
A lighting device comprising:
- a light emitting section;
- and
- a reflective member that is drawably retracted in the light emitting section and is provided with reflectors that are deployed by a drawing operation to reflect a part of light irradiated from the light emitting section so that area of the reflectors in a deployed state will be more than area of the reflectors in a retracted state.
An image pickup apparatus comprising:
- an image pickup unit configured to pick up an image of an object:
- and
- a lighting device comprising:
- a light emitting section that irradiate the object;
- and
- a reflective member that is drawably retracted in the light emitting section and is provided with reflectors that are deployed by a drawing operation to reflect a part of light irradiated from the light emitting section so that area of the reflectors in a deployed state will be more than area of the reflectors in a retracted state.
A lighting device comprising:
- a light emitting section;
- and
- a reflective member that has a first reflector and a second reflector that are retractable in a retraction part provided in the light emitting section and reflects a part of light irradiated from the light emitting section by the first reflector and the second reflector that have been drawn from the retraction part,
- wherein the first reflector and the second reflector are retracted in the retraction part in a state where the first reflector at least partially overlaps with the second reflector,
- wherein the second reflector is drawn from the retraction part in connection with shift movement of the first reflector in a direction in which the first reflector is drawn from the retraction part, and
- wherein overlap area between the first reflector and the second reflector in a state where the first reflector and the second reflector have been drawn from the retraction part is smaller than the overlap area in a state where the first reflector and the second reflector are retracted in the retraction part.
