For reaching above-mentioned purpose, the utility model provides a kind of chargeable light fixture, and it comprises: a USB input block, in order to input a direct current; One booster circuit, is electrically connected with USB input block, so that direct current is boosted to 6.5V; One control and management unit, is electrically connected on booster circuit; One battery unit, comprises several rechargeable battery, be electrically connected on control and management unit and this control and management unit be by boosting after this direct current this battery unit is charged; One lighting unit, is electrically connected on battery unit.

Preferably, a trickle charge pattern is transformed into when control and management unit controls battery unit of the present utility model charges to 350mah.

Preferably, charging is stopped when control and management unit controls battery unit of the present utility model charges to 5V ~ 5.6V.

Preferably, when the voltage of control and management unit controls battery unit of the present utility model is lower than 3.3V, stop lighting unit supply electric power.

Preferably, the utility model more comprises a LED indicating member, is electrically connected on control and management unit, when battery unit charges, sends light.

Preferably, battery unit of the present utility model includes four rechargeable batteries.

Preferably, those rechargeable batteries of the present utility model are Ni-MH battery.

The beneficial effects of the utility model are: chargeable light fixture of the present utility model, it utilizes booster circuit that the direct current of input is boosted to 6.5V, by control and management unit, the direct current after boosting is charged to battery unit, can be filled full, to supply the required electric power of lighting unit.

Chargeable light fixture 100 USB input block 10

Booster circuit 20 control and management unit 30

Battery unit 40 rechargeable battery 41

Lighting unit 50 LED indicating member 60

External power source 200.

Detailed description of the invention

For ease of the central idea that the utility model is represented in above-mentioned utility model content one hurdle is described, hereby express with specific embodiment.In embodiment, various different object is the ratio in being suitable for enumerating explanation, but not in the ratio of actual components and to draw, conjunction is first chatted bright.

Refer to shown in Fig. 1, chargeable light fixture 100 of the present utility model, it includes USB input block 10, booster circuit 20, control and management unit 30, battery unit 40 and a lighting unit 50.

USB input block 10 can be a USB socket, in order to be electrically connected on the external power source 200 that has USB plug, such as, is computer, and to input a direct current, and USB input block 10 input power is 5V/500mah.

Booster circuit 20, is electrically connected with USB input block 10, and in order to be carried out by the direct current of input boosting and voltage stabilizing becomes a fixed voltage, in the utility model, fixed voltage is 6.5V.

Control and management unit 30, is electrically connected between booster circuit 20 and battery unit 40, the fixed voltage exported in order to control and management booster circuit 20 and then charge to battery unit 40.In the utility model, battery unit 40 comprises a plurality of rechargeable battery 41, is preferably four Ni-MH batteries.

Lighting unit 50, is electrically connected on battery unit 40, supplies electric power and gives lighting unit 50, produce action to make lighting unit 50 to make battery unit 40.

Hold, control and management unit 30 of the present utility model can control to be transformed into a trickle charge pattern when battery unit 40 charges to 350mah, and in battery unit 40 charge to 5V ~ 5.6V can control its stop charging, avoid overcharging situation to occur, in addition, when the voltage that control and management unit 30 further can control battery unit 40 is lower than 3.3V, stop supplying electric power to lighting unit 50.

And the utility model further comprises a LED indicating member 60, be electrically connected on control and management unit 30, when charging for battery unit 40, send light.

So, the utility model utilizes USB input block 10 to be connected with external power source 200, can charge to battery unit 40 to direct current mode to direct current, make the utility model not need to use extra transformer to charge to battery unit 40, it is more convenient to use.

Moreover, the voltage of rechargeable battery 41 of the present utility model is 1.4V, when USB input block 10 input dc power, and the fixed voltage of 6.5V is formed via booster circuit 20 boosting, to charge to four rechargeable batteries 41, and can be filled full, can only reach compared to existing charging modes and have more practicality and both effectiveness to filling 3 rechargeable batteries.

Although the utility model explains with a most preferred embodiment, be skillful in this those skilled in the art can not depart from the utility model spirit with category under do various multi-form change.Above illustrated embodiment, only in order to the utility model to be described, is not used to limit scope of the present utility model.Such as do not disobey the utility model various modifications of being engaged in of spirit or change, all belong to the utility model claim.
