Abstract
An electric torch adopting an USB (Universal Serial Bus) interface to charge comprises at least one light-emitting diode (LED) bulb for generating light beam, an embedded rechargeable battery which is connected with the LED bulb and is used for providing working voltage for the LED bulb, the USB interface is connected with a power supply device, a voltage conversion and charging circuit which is used for charging the embedded rechargeable battery and converting the voltage into the working voltage required by the LED bulb, and a press-button which is used for shutting on or shutting off the power supply for controlling the LED bulb; so that the use cost on the battery is reduced and the problem of environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of flashlight, relates in particular to a kind of flashlight that adopts the USB interface charging.
Background technology
In the daily life, people often use flashlight lighting, ought look for thing in corners, it is very inconvenient that big flashlight seems again, and present flashlight mostly is use is battery, and cost is high like this, and the environmental pollution that battery brought can't neglect equally.When using battery, because the limitation of battery volume, make the flashlight dainty small-sized more scabrous problem that becomes that becomes.
The develop rapidly of modern science and technology, the widespread usage of computer make the USB technology become to reach its maturity and make things convenient for.
In sum.How to make flashlight have sufficient power supply,, reduce old and useless battery and bring environmental pollution to become to continue the problem of solution to environment to reduce the use cost that is used for reducing flashlight that makes of battery.
Summary of the invention
The utility model has overcome the above-mentioned defective of existing flashlight, and a kind of flashlight that adopts the USB interface charging is provided.
In order to reach above-mentioned technical essential, the technical solution of the utility model is as follows:
Adopt the flashlight of USB interface charging, comprising: at least one LED bulb produces light beam; An embedded rechargeable battery is connected with the LED bulb, and the operating voltage of LED lamp is provided; A USB interface is connected with power supply device; Voltage transitions and charging circuit in order to embedded rechargeable battery charging, and are the needed operating voltage of LED lamp with voltage transitions; A button is used for conducting or cuts off the electricity supply control LED lamp.
Described voltage transitions and charging circuit and voltage conversion circuit.Described charging circuit is a charging integrated chip, is connected with embedded rechargeable battery, and described voltage transitions integrated chip is connected with the LED lamp, and the power supply device that described USB interface connects is notebook computer or PC.
Described USB interface place is provided with a bonnet.
The utility model adopts the flashlight of USB interface charging, utilize USB interface to do quick charge, because present popularizing of computer, so it is very convenient to charge, the use that equally also can effectively reduce battery reduces purchases the use cost of battery, and has reduced problem of environmental pollution.
