Abstract
The utility model relates to a chargeable electric torch, which is provided with a solar charging panel, a direct-current power supply charging socket, a chargeable storage battery and a light emitting diode (LED) lamp for illumination, wherein a charging circuit is connected with a discharging circuit in parallel, and the electric torch is further provided with a power supply inverter. The charging circuit is connected with the discharging circuit in parallel, so the charging circuit is relatively independent from the discharging circuit, and the energy consumption can be reduced; and the entire circuit design is simple, and the cost is low. In addition, two charging modes are set, so the application of the electric torch is ensured not to be influenced by the environmental variation; and at the same time the power supply inverter is connected with external equipment, so the function of the electric torch is further expanded to be a power supply device, and effects of environmental protection and energy conservation can be realized.
Description
Technical field
The utility model relates to a kind of chargeable flashlight, relates in particular to a kind of flashlight that can be used as charge power supply.
Background technology
Solar charging electric torch in the market, the general single charge mode that all adopts solar panel charging, making flashlight may cause intrasystem battery can not in time obtain replenishing of electric energy after long-time the use because of the reason of weather can not normally use.Be not subjected to the influence of Changes in weather for the use that guarantees flashlight, need a flashlight that not only can charge but also can charge by external direct current power supply by solar energy of design, can satisfy the user like this and can can not normally not work for a long time to the additional whole system that makes that this system carries out electric energy by external DC power supply when solar panels can not provide electric energy when insufficient light the time because of conditions such as weather.Thereby provide safeguard for the long-time steady operation of flashlight, increase convenience and the security reliability used.
Summary of the invention
The purpose of this utility model is to provide a kind of flashlight that can charge by solar energy and dc source, and flashlight can also charge to miniaturized electronics as external power supply equipment simultaneously.
For achieving the above object, the utility model adopts following technical scheme: a kind of chargeable flashlight, the LED lamp that it has solar charging panel, dc source charging socket, chargeable storage and is used to throw light on, the design in parallel with discharge circuit of described charging circuit further is provided with power inverter on the flashlight.
Compared with prior art, the utlity model has following beneficial effect: avoided the phenomenon that flashlight can not normally use to take place by the DC charging socket is set, be connected with external equipment and make that this flashlight can also be as charge power supply by power inverter is set simultaneously under the condition of solar irradiation deficiency.
Description of drawings
Fig. 1 is the utility model electrical property connection diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
A kind of chargeable flashlight of the utility model, the LED lamp 7 that it has solar charging panel 1, chargeable storage 2, dc source charging socket 3 and is used to throw light on, the design in parallel with discharge circuit of described charging circuit further is provided with power inverter 9 on the flashlight.Described charging circuit is meant the loop that solar charging panel 1 and dc source charging socket 3 form respectively and between the chargeable storage 2, and discharge circuit is meant that solar charging panel 1 and dc source charging socket 3 are respectively and the loop that forms between the LED lamp 7 of illumination and power inverter 9
Described DC charging loop is provided with counnter attack and fills diode 4.
Described power inverter 9 is connected with external equipment, and described LED lamp 7 is connected with LED Drive and Control Circuit 6, and described Drive and Control Circuit one end is connected with the break-make of LED gauge tap 5 in order to control LED lamp.
Described LED lamp 7 is arranged in parallel with power inverter 9.
The utility model passes through charging circuit design in parallel with discharge circuit, and the charging and the discharge circuit that make are relatively independent, have reduced energy consumption; The integrated circuit simplicity of design, cost is lower.The influence that use that two kinds of charge modes have guaranteed flashlight is not subjected to environmental change is set in addition, and the function that is connected flashlight with external equipment by power inverter simultaneously extends further to power-supply device, reaches the effect of environmental protection and energy saving.
