Abstract
The present invention is directed to a small-sized stroboscopic light emitting device that controls disorder in light distribution (orientation) characteristic caused by a shape of the reflector, and achieves a homogeneous light quantity distribution. The stroboscopic light emitting device includes an illuminator, a reflectorfor reflecting light from the reflector, and a lensfor allowing the light reflected by the reflectorto pass through and illuminate outwardly, and the lenscontains a fillerin the base material. A refractive index and a mean particle size of the filler are between or equal to 1.3 to 2.8 and between or equal to 0.1 μm to 20 μm, respectively, and the filler is contained in the base material at the rate between or equal to 0.1 parts by weight to 3.0 parts by weight, per 100 parts by weight of the base material. Since the filler diffuses the passing light adequately, even though the reflector is provided with a bend, local disorder in light distribution (orientation) characteristic caused by the bend can be suppressed.
