Title: Stroboscope device
Inventor: MASUDA TAKURO
IPC: G03B17/04
Filed: 1999-08-12
Abstract: PROBLEM TO BE SOLVED: To make obtainable an excellent light distribution characteristic even when photographing is executed by irradiating a peripheral part brightly and using a wide-angle lens by making a stroboscope device have the maximum light quantity in a direction different from that of the optical axis of a stroboscope in parallel with that of a photographing lens. SOLUTION: Since light made incident on a plane and smooth subject is reflected by an equal angle to normal line by the law of light reflection, the quantity of light returned to a camera is more reduced in comparison with a light beam reflected on an identical optical path like a light beam in the optical axis direction of the stroboscope. This phenomenon becomes more remarkable when the wide-angle lens whose viewing angle is specially large is used. Then, the maximum quantity of stroboscopic light is emitted in the direction different from that of the optical axis of the stroboscope, differently from a conventional light distribution characteristic figure so as to correct the prescribed-angle to reduce the emitted light quantity. The emitted light quantity is gradually reduced by the angle set larger than the irradiating angle having the maximum emitted light quantity.  Therefore, it is preferable that the waste light quantity emitted outside the field angle, that is, outside a photographic picture frame is reduced because the irradiation angle having the maximum light quantity is set smaller than the field angle (half field angle is 40 deg., for example).
