In order to solve the above problems, Chinese patent ZL03246859.8 " vehicle charger light-emitting device " discloses a kind of automobile-used charger for mobile phone lighting device, it comprises decompression voltage regulator, pressure regulation feedback circuit, mobile phone charging interface, also be provided with battery charger in the charger, battery charger connects rechargeable battery, and rechargeable battery connects light emitting source.Because mobile phone charging interface is connected with the pressure regulation feedback circuit, to cell-phone charging be pulsed voltage, with pulsed voltage to mobile phone directly the charging meeting mobile phone is caused certain damage; And described light emitting source directly is connected with rechargeable battery, when the low a little illuminating effect that a bit will influence light emitting source of voltage.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of automobile-used charger for mobile phone lighting device of good illumination effect, and so automobile-used charger for mobile phone lighting device can also guarantee the useful life of mobile phone effectively.
The technical scheme that its technical problem that solves the utility model adopts is: automobile-used charger for mobile phone lighting device, include decompression voltage regulator, mobile phone charging interface, charging circuit, battery and light emitting source, it is characterized in that: be connected with decompression voltage regulator after mobile phone charging interface and the charging circuit parallel connection, charging circuit connects battery, battery connects the LC oscillating circuit, and the LC oscillating circuit connects light emitting source.
As further improvement of the utility model, be provided with switch between described battery and the LC oscillating circuit, described mobile phone charging interface is parallel with indicating circuit, and described light emitting source is a high brightness LED.
The beneficial effects of the utility model are: owing to be connected with decompression voltage regulator after mobile phone charging interface of the present utility model and the charging circuit parallel connection, electric current obtains the stable DC charging voltage through mobile phone charging interface behind the decompression voltage regulator, utilizes the stable DC charging to have guaranteed mobile phone effectively useful life; In addition, because light emitting source is parallel with the LC oscillating circuit, the light emitting source two ends can obtain a pulse voltage that amplitude is bigger, same cell voltage, light emitting source, and the light that light emitting source of the present utility model sends is brighter, and service time is permanent.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is preferred embodiment ifq circuit figure of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, automobile-used charger for mobile phone lighting device, include decompression voltage regulator 1, mobile phone charging interface PE, charging circuit 2, battery BT and light emitting source 5, described mobile phone charging interface PE is connected with decompression voltage regulator 1 with charging circuit 2 backs in parallel, charging circuit 2 connects battery BT, battery BT connects LC oscillating circuit 3, LC oscillating circuit 3 connects light emitting source 5, described LC oscillating circuit 3 is connected in parallel with light emitting source 5, also is connected with switch SW between parallel circuits that LC oscillating circuit 3 and light emitting source 5 are formed and the battery BT.
Wherein, described decompression voltage regulator 1 comprises Based Intelligent Control element IC, and the pin A of Based Intelligent Control element IC is connected with the positive pole of capacitor C 1, cigar lighter power supply, and pin C connects the anode of diode D1, and the negative electrode of diode D1 connects mobile phone charging interface PE; Described charging circuit 2 is composed in series with diode D2 by resistance R 2, and resistance R 2 is connected with the negative electrode of diode D1, and the negative electrode of diode D2 then is connected with the positive pole of battery, and the positive pole of described battery is connected with switch SW.Described LC oscillating circuit 3 comprises inductance L 1, one end of inductance L 1 is connected with the emitter of triode Q1, the other end connects the collection emitter-base bandgap grading of triode Q2, the base stage of triode Q2 is connected with the collection emitter-base bandgap grading of triode Q1, the collection emitter-base bandgap grading of described triode Q2 connects capacitor C 2, capacitor C 2 is connected with resistance R 4, also connects with the base stage that is connected triode Q1 between capacitor C 2 and the resistance R 4.When the positive pole and the negative pole that the A utmost point of charger, the B utmost point are connected on the cigar lighter power supply respectively, electric current will obtain the stable DC charging voltage through decompression voltage regulator 1 back mobile phone charging interface PE, utilizes the stable DC charging can guarantee the useful life of mobile phone effectively; In addition, this utensil is done the torch time spent, as long as transfer to from the automobile cigarette lighter power supply, the SW that closes a switch gets final product; Because light emitting source 5 is parallel with LC oscillating circuit 3, light emitting source 5 two ends can obtain a pulse voltage that amplitude is bigger, same cell voltage, light emitting source, and the light that light emitting source of the present utility model sends is brighter, and service time is permanent.
