Patent ID: 7802904

Claim:
An electronic stroboscope comprising: a light discharge tube radiating light in substantially all directions from an outer surface thereof; and a reflector in which the light discharge tube is disposed, the reflector comprising a first reflecting part that reflects light radiated from the light discharge tube and a second reflecting part that reflects light directly radiated from the light discharge tube and light reflected from the first reflecting part to exit out of an opening of the reflector, wherein: an X-axis is defined as an axis extending parallel to the opening from the center of the light discharge tube as viewed in a side cross-section including the light discharge tube and the reflector, the first reflecting part includes first curved parts formed on an opposite side of the light discharge tube from the opening, planar parts connected to the first curved parts and disposed closer to the opening than the first curved parts, and circular parts connected to the planar parts and disposed closer to the opening than the planar parts, and the second reflecting part includes second curved parts connected to the circular parts of the first reflecting parts and disposed closer to the opening than the first curved parts, wherein only one planar part is disposed between each first curved part and each circular part; the center of a circle on which the circular parts are based substantially coincides with the center of the light discharge tube; and lines extending from the connection points where the circular parts and the second reflecting parts meet and passing through the center of the light discharge tube intersect with portions between both endpoints of the first curved parts.
