[0032] The block diagram of the circuitous philosophy is shown in FIG. 6; it can be implemented by the idiographic circuit shown in FIG. 8 and FIG. 9.

[0033] The first circuit connection mode of the lighting device of this invention, as shown in FIG. 8, comprising a power source BAT1, a trigger switch K1, a current-limiting resistor R2 and a light-emitting diode LED1; the power source BAT1 supplies the lighting unit via K1, the mentioned lighting unit is composed of the resistor R2 and the light-emitting diode LED1 which connect in series; the cathode of the light-emitting diode LED1 is earthling. 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.

[0034] The second circuit connection mode of the lighting device of this invention, as shown in FIG. 9, comprising a power source BAT1; a motor M1; a trigger which composed of a resistor R3, a capacitor C1, a switch K1, a dynatron Q1; and a lighting unit which composed of a current-limiting resistor R2 and a light-emitting diode LED1. The current-limiting resistor R2 is connected in series to the light-emitting diode LED1. The cathode of the light-emitting diode LED1 is earthing. The motor M1 is connected in parallel to the lighting unit. The base of the dynatron Q1 is connected to the cathode of the power source via the resistor k3 and the switch K1 in turn. 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.

[0035] 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.

[0036] The third circuit connection mode of the lighting device of this invention is shown in FIG. 10. In this connection mode, the lighting unit is different from the first connection mode. This lighting unit is composed of a control IC, a oscillate resistor R1, two trigger switches K1 and K2, a current-limiting resistor R2, and light-emitting diodes LED1,LED2,LED3. R1 is connected to the OSCI end and OSCO end of the control IC. The cathodes of LED1,LED,LED3 are connected to the output ends OUT1,OUT2,OUT3, respectively; the anodes of these three LEDs are together connected to K1 via the current-limiting resistor R2. When K1 is separated, the lighting device will not emit light; when K2 is shut, the motor will get power and run. Due to that the mentioned lighting unit and the rotating shaft of the motor are fixed together in a certain mode, and that a control IC is added to this circuit for controlling the LEDs, the lightening of the LEDs could be controlled by controlling the predetermined lightening mode of the control IC, so to make the LEDs generate more lightening effect.

[0037] The fourth circuit connection mode of the lighting device of this invention is shown in FIG. 11. It uses the trigger of the second connection mode and the lighting unit of the third mode to replace the corresponding parts of the first connection, so it have the functions of all the above three connection modes, and can occur more lighting effects.

[0038] The fifth circuit connection mode of the lighting device of this invention is shown in FIG. 12. It adds a pins HOLD to the control IC of the third connection mode for connecting the energy storage element. 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.

[0039] Although the quantity of the LEDs is different in each of the above five connection mode, here it just for a better description and cannot be thought to be a restrict for the LED's quantity. 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. Of course that the above mentioned connection modes are only part of the application of this invention, so long as one connection mode is an equivalent substitution for anyone of the above mentioned connection modes, it belongs to the protection scope of this invention.

[0040] Referring now to FIG. 13, an embodiment of the control IC of this invention is shown. Being different from the common Control IC, the logic earth VSS of the organ 103-114 which for controlling flash mode in this Control IC is independent; the logic earth VSS is connected and isolated to the system earth GND via an isolation component; the isolation component may be a diode (D1); the diode's anode is connected to the logic earth VSS; the logic earth VSS is connected to the outside of the control IC by a pins HOLD in order to connect the energy storage element; 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. 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.

[0041] 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.

[0042] FIG. 14. is the stereoscopic view of this Embodiment 2 of this invention. As shown in this fig, there is an swinging device 10 and an oscillating shaft 9. The mentioned swinging device 10 includes a power source 1, a trigger 2 and a lighting unit 3, wherein the power source 1 supplies the lighting unit 3 via the trigger 2. When the swinging device 10 is given a force and oscillates, the trigger 2 will work and so as to make the lighting unit lightening meanwhile oscillating along the oscillating shaft 9; thus it can get more beautiful lighting effect than those lighting device whose lighting unit is fixed. By adjusting the shape or position or the lightening and flashing frequency of the lighting unit, it can generate more beautiful lightening effect shaped as real line-single color or colorful concentric circle, pitch arc, broken line or colorful concentric circle, pitch arc and so forth.

[0043] FIG. 15. is the stereoscopic view of this Embodiment 3 of this invention. The rotating mechanism includes a power source 1, a trigger 2 and a lighting unit 3. The power source 1, the trigger 2 and the lighting unit 3 are integrated together to be a round shaped or round-liked shaped structure 11. When this structure 11 is given a force, the mentioned trigger 2 will work so as to make the lighting unit 3 lightening and rolling; thus it can get more beautiful lighting effect than those lighting device whose lighting unit is fixed. By adjusting the shape or position or the lightening and flashing frequency of the lighting unit, it can generate more beautiful lightening effect shaped as real line-single color or colorful concentric circle, pitch arc, broken line or colorful concentric circle, pitch arc and so forth.

[0044] In this Embodiment 4, the motor and the lighting unit independently possess their own power source. To realize the effect of this Embodiment 3, it just needs a little bit changes of the circuits in the above Embodiments.

[0045] The power source which mentioned in the each of the above four Embodiments of this invention can be a single battery or some Li—Mn batteries connected in series, or some alkali-Mn batteries connected in series, or some Li—Mn batteries and alkali-Mn batteries connected in series, or rechargeable batteries, or solar batteries. Normally the voltage of single Li—Mn battery is 3 V due to its special stuff property, so the voltage of the Li—Mn batteries connected in series is above or equal 6 V. The common models of the Li—Mn batteries are like CR2032, CR2450 and other CR series batteries. In a same way, the voltage of single alkali-Mn battery is 1.5 V due to its special stuff property. The common models of the alkali-Mn batteries are like AG13, AG10 and other AG series batteries. In each of the above four Embodiments of this invention, only when the circuit voltage is above 1.5 v, the circuit can work ordinary, namely the LED can emit light ordinary; so the alkali-Mn batteries here must be used in series in order to make sure that the voltage of the circuit above 1.5 V. In a similar way, the alkali-Mn battery and the Li—Mn battery must also be connected in series if they are used together, that also due to their special stuff properties.
