1. A lighting device, comprising a power source, a trigger, and a lighting unit, wherein the power source supplies power to the lighting unit via the trigger, wherein the trigger comprises a dynatron, a capacitor, a resistor, and a switch, wherein the dynatron is powered by the power source for directing the lighting unit when the switch is shut, and wherein the capacitor is charged up when the switch is shut such that the charged up capacitor can temporarily supply power to the dynatron when the switch is subsequently opened;

  • and wherein the lighting device further includes a mechanism that rotates, oscillates, or rolls the lighting unit, wherein the mechanism that rotates the lighting unit includes a motor, wherein the motor includes a rotating shaft that is connected to the lighting unit a part of the lighting unit; and

    wherein the lighting unit is connected to a control unit, wherein the lighting unit comprises a current-limiting resistor and a light-emitting diode, wherein the current-limiting resistor is connected in series to the light-emitting diode, and a cathode of the light-emitting diode is grounded, wherein the motor is connected in parallel to the lighting unit, wherein a base of the dynatron is connected to a cathode of the power source via the resistor and the switch, wherein the capacitor connects an anode of power source and a node located between the resistor and the switch, wherein an emitter of the dynatron is connected to the anode of the power source, wherein a collector of the dynatron is connected to the current-limiting resistor, and wherein the light-emitting diode and the rotating shaft are fixed together by a fixture used for setting the lighting unit or the part of the lighting unit.
