Lighting device reflecting part of irradiation light and image pickup apparatus using lighting device
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.
1. 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.
2. The lighting device according to claim 1 , wherein the reflectors are rotatably engaged.
3. The lighting device according to claim 1 , wherein the reflective member comprises a center reflector and left and right reflectors arranged at left and right of the center reflector so that the left and right reflectors may not overlap mutually from the retracted state to a state where the reflectors are deployed by the drawing operation.
4. The lighting device according to claim 3 , wherein each of the left and right reflectors has a follower that moves along a cam groove formed in an exterior member.
5. The lighting device according to claim 1 , wherein the reflective member has a part of which a contour shape becomes approximately circular in the deployed state.
6. The lighting device according to claim 1 , wherein the reflectors are engaged so as to allow slide operations and deploy in parallel to a drawing direction by the drawing operation.
7. 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.
8. 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.
9. The lighting device according to claim 8 , wherein a cam groove is formed in the retraction part and a follower that moves along the cam groove is formed in the second reflector.
10. The lighting device according to claim 8 , wherein the reflective member has a part of which a contour shape becomes approximately circular in the state where the first reflector and the second reflector have been drawn from the retraction part.
