<P>PROBLEM TO BE SOLVED: To increase light radiated in a radiation direction (within an angle of view) of a stroboscope device. <P>SOLUTION: The stroboscope device includes: a tubular light source 1 extending in a right-and-left direction; a reflector 2 reflecting the light radiated from the light source 1; and a light guide lens 3 guiding direct light radiated from the light source 1 and/or reflected light reflected by the reflector 2 after it is radiated from the light source 1. The light guide lens 3 is constituted to be divided into a plurality of lens parts 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h and 3i arranged in the right-and-left direction, and the lens parts 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h and 3i are provided with right-sidewalls 3a2, 3b2, 3c2, 3d2, 3e2, 3f2, 3g2, 3h2 and 3i2 extending to a front side while spreading to the right side with respect to the main optical axial line L of the stroboscope device, and left-sidewalls 3a1, 3b1, 3c1, 3d1, 3e1, 3f1, 3g1, 3h1 and 3i1 extending to the front side while spreading to the left side with respect to the main optical axial line L of the stroboscope device. <P>COPYRIGHT: (C)2009,JPO&INPIT |
