[0021] Specifically, in this embodiment, by disposing the third circuit board 5 between the first circuit board 2 and the second circuit board 3, since circuit components can also be placed on the third circuit board 5, the above arrangement further improves the utilization rate of the longitudinal space inside the stroboscope.
