There is a motor M1 is connected to the node which locates between the trigger switch K1 and the resistor R2. When the trigger switch is separated, the lighting device will not emit light; when the trigger switch is shut, the motor will get power and run. Due to the mentioned light-emitting diode and the rotating shaft of the motor are fixed together in a certain mode, the running of the motor can make the light-emitting diode rotating along the rotating shaft, so as to get lightening effect which shaped like a round.

The capacitor C1 is connected to the nodes which are between the anode of the power source and the resistor R3 and the switch K1. The emitter of the dynatron Q1 is connected to the anode of power source; the collector of the dynatron Q1 is connected to the current-limiting resistor R2. When the trigger switch is shut, the resistor R3 and the capacitor C1 will discharge to the earth, then the dynatron Q1 will be put through, and the motor M1 will be rotating because of getting power from the power source BAT1. Due to the mentioned light-emitting diode and the rotating shaft of the motor are fixed together in a certain mode, the running of the motor can make the light-emitting diode rotating along the rotating shaft, so as to get lightening effect which shaped like a round. This second circuit connection mode of the lighting device this invention has improved the trigger which is shown in FIG. 8. The resistor R3 and the capacitor C1 which are shown in FIG. 9 can be charged up so as to keep energy; even if the switch is separated, the dynatron Q1 will still be electriferous for quite a while. By selecting an appropriate parameter of the capacitor C1 and the dynatron Q1, we can get a control to the rotating term of the lighting unit and the motor, so as to get more lightening effect.
The block diagram of the circuitous philosophy of this invention is shown in FIG. 7; it can be implemented by the idiographic circuit shown in FIG. 10 and FIG. 12.

Here a capacitor is used as the energy storage element; and the capacity of this capacitor is proportional to the term of the energy maintenance. Because such a small portion of circuit which inside the control IC for keeping energy consumes very little energy, it could maintain the components in the circuit being electriferous for quite a long term, so as to make the flash being continuous, further to solve the technical problems that issued by the above mentioned invention purposes. Added to the function of possessing the characteristics of the third connection mode, this fifth circuit connection mode is under the control of the control IC to implement the functions such as keeping the flash when power interrupted, so as to get more lighting effects.

Due to the LEDs are fixed on the rotating shaft and rotate along the shaft, it can get variety lighting effects by properly arranging the positions of the LEDs. For example, it will get several different size lighting circles which shaped as round when arranging the LEDs on the circumferences of each different sized circle centered on the rotating shaft; and it will get several flowing lighting circles if the control IC transmits the signals to the LEDs in different turn; it will of course get more lighting effects by changing the signal transmitting mode of the control IC. If distributing the LEDs with different colors on different positions of the circumference of a certain radius circle centered on the rotating shaft, and due to the rotating of the motor plus the flash lingering effect of people, it will be seen as a colorful lighting circle image which is different from the former single color one.

Because such a small portion of circuit which inside the control IC for keeping energy consumes very little energy, it could maintain the components in the circuit being electriferous for quite a long term, so as to make the flash being continuous, further to solve the technical problems that issued by the above mentioned invention purposes. In addition, because there is a LED D1 between the logic earth VSS and the system earth GND, the reference electrical level of this circuit portion will be different from the rest circuit, in this way, abnormal phenomenon may occurs when the system voltage is too low; to solve such a problem, it only needs a electrical level matcher adding between this portion and the rest portion of the circuit.
The above mentioned control IC possesses pins HOLD connects the energy storage element, so as to make the power source of the portion which for controlling flash mode of the control IC is independent from the system power source; the control IC may be supplied power by a energy storage element such as a capacitor C2 when the system power is interrupted, so as to keep the state of the component which for controlling the current flash mode and to get more flash effects; although here the capacitor C2 is connected between the pins HOLD and the cathode of the power source to implement this function, the capacitor C2 can also be connected between the pins HOLD and the anodes of the power source so long as the circuit changed a little bit; such changes are obvious to the common technicists in this field. In addition, the above mentioned isolation component is actually a simple PN knot; here not only a LED can be used as the isolation component, but also a dynatron or other equal component can be used and also have the same function.
