Abstract
The utility model discloses an flashlight, which comprises a main body 1, a battery box 4 and a battery E, wherein, a series circuit is formed among a battery E, a switch K and a LED bulb, one way of the positive pole of the battery E is connected with the positive pole of the LED through an inductor L2, the other way thereof is connected with the base electrode of a triode Q through the series resistance R of a inductor L1, the collecting electrode of the triode Q is also connected with the positive pole of the LED, and the emitting electrode of the triode Q and the negative pole of the LED are connected with the negative pole of the power source. The flashlight has the advantages that only one dry battery is required to be used for supplying power for the LED flashlight, and the dry battery with different models can be used for one identical flashlight.
Description
Technical field
The utility model relates to a kind of flashlight, particularly a kind of LED flashlight.
Background technology
The LED flashlight generally is that three joints or multiple batteries are powered to LED as power supply on the market now, and a batteries can't start flashlight at all.Also having existing flashlight generally all is the battery that a kind of flashlight of model is just joined a kind of model, the battery of different model can not be used for the flashlight of a certain fixedly model.
Summary of the invention
At the shortcoming of existing flashlight, it is a kind of only with a joint dry cell that the utility model provides, and the novel flash light of the dry cell of suitable different model.
To achieve these goals, the measure taked of the utility model is:
A kind of flashlight, comprise main body 1, battery case 4 and battery E, battery E wherein, K switch constitutes a series circuit between the LED bulb, battery E positive pole is leaded up to inductance L 2 and is connected the anode of LED, another route inductance L 1 series resistance R is connected with the base stage of triode Q, and the colelctor electrode of triode Q also links to each other with the anode of LED, and the emitter stage of this triode Q and the negative electrode of LED link to each other with power cathode;
Described LED is a LED lamp group in parallel;
One end of described battery case 4 is a Movable bracket 6;
The Movable bracket 6 of described battery case 4 is installed on the main body 1 by spring 61;
One able to turn on or off side cover 3 is arranged on the position of main body 1 corresponding to battery case of flashlight;
The bonnet 2 of flashlight links to each other with main body 1 by screw thread.
The beneficial effects of the utility model are: only with can powering to the LED flashlight once the joint dry cell, and different model can be suitable for same flashlight in battery.

The specific embodiment
See also its implementation process of description of drawings:
A kind of flashlight, comprise main body 1, battery case 4 and battery E, also has eyeglass 7 on the lamp holder, electricity bowl 8, battery E wherein, K switch, constitute a series circuit between the LED bulb 5, this is the basic system of common LED flashlight, and improvement of the present utility model is as follows: battery E positive pole is leaded up to inductance L 2 and is connected the anode of LED, and another route inductance L 1 series resistance R is connected with the base stage of triode Q, the colelctor electrode of triode Q also links to each other with the anode of LED, and the emitter stage of this triode Q and the negative electrode of LED link to each other with power cathode.So just can make the common dry cell of 1 joint just can be to 3-4 common LED bulb powered, main cause be because adopted above-mentioned booster circuit, and the voltage that is only the common dry cell of a batteries is upgraded to and has met voltage that LED powers.Certainly, LED not only is one or many, also can be the LED lamp group of parallel connection simultaneously.One end of battery case 4 is a Movable bracket 6, and the Movable bracket 6 of battery case 4 is installed on the main body 1 by spring 61.Make Movable bracket can regulate length like this, the battery of different model is placed in the battery case and can be suitable for.For the ease of putting into or take out dry cell, an able to turn on or off side cover 3 is arranged on the position of main body 1 corresponding to battery case of flashlight, the bonnet 2 of flashlight links to each other with main body 1 by screw thread.
Above embodiment is a kind of embodiment of the present utility model, and it all is protection domain of the present utility model that those skilled in that art's routine is replaced.
Claims (6)
