A lighting device provides with a mechanism which rotates, oscillates or
rolls a lighting unit, and includes a power source (1), a trigger (2), a
lighting unit (3) and a motor (4), wherein the power source (1) supplies
power to the lighting unit (3) and the motor (4) via the trigger (2). The
lighting device further includes a control unit which is connected in
parallel to the lighting device. By changing internal circuits of the
control unit, a pins which connects to an energy storage element is set,
therefore the lighting unit flashes in a predetermined sequence after
interruption of power is resumed, and the lighting unit moves in a
certain track, occurring a path in which position of light spots changed.
