it can be implemented by the idiographic circuit shown in fig1 and fig1 . the third circuit connection mode of the lighting device of this invention is shown in fig1 . 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 r 1 , two trigger switches k 1 and k 2 , a current - limiting resistor r 2 , and light - emitting diodes led 1 , led 2 , led 3 . r 1 is connected to the osci end and osco end of the control ic . the cathodes of led 1 , led , led 3 are connected to the output ends out 1 , out 2 , out 3 , respectively ; the anodes of these three leds are together connected to k 1 via the current - limiting resistor r 2 . when k 1 is separated , the lighting device will not emit light ; when k 2 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 . the fourth circuit connection mode of the lighting device of this invention is shown in fig1 . 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 . the fifth circuit connection mode of the lighting device of this invention is shown in fig1 . 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 . 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 &# 39 ;

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 . referring now to fig1 , 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 ( d 1 ); the diode &# 39 ; 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 d 1 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 c 2 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 c 2 is connected between the pins hold and the cathode of the power source to implement this function , the capacitor c 2 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 . fig1 . 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 . fig1 . 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 . 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 . 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 .
