Abstract
The utility model relates to a flashlight and pertains to the field of portable illuminating device, which is characterized in that: a flashlight body, a switch, an illuminant, a reflector plate and a power supply device are arranged; the front end of the reflector plate is provided with a light inlet plate and the illuminant applies the LED light emitting diode and the power supply device is a permanent magnetism that is arranged in the coil; the two ends of the coil are connected with the input ends of the full wave rectifying circuit, while an electrolyte capacitance is crossed over the output ends of the full wave rectifying circuit and the switch is connected in parallel at the two ends of the electrolyte capacitance after the switch is connected with the LED light emitting diode in series. The utility model needs not any battery but can automatically generate electricity by rocking the flashlight back and forth and then the electricity is stored by electrolyte capacitance and illuminant effect is good.
Description
Affiliated technical field
The utility model relates to the portable illumination device field, especially a kind of flashlight that need not battery.
Background technology
At present, known flashlight generally is made up of cylindrical shell, reflector, direct current incandescent lamp bulb, dc-battery and switch, and its luminous intensity is less, and needs the periodic replacement battery.Chinese patent ZL022303111 discloses a kind of generating, lighting device voluntarily, it is to utilize a default clamshell main body to form suitable accommodation space in inside, and in this clamshell main body inside be respectively equipped with driven unit, electrification component and electronic circuit board, when the user in emergency or when outdoor, utilize the rocking handle rocking-turn of driven unit, impel this electrification component generating, import the luminous effect of playing flashlight of light-emitting component in the electronic circuit board, this power-generating illuminating device complex structure, use very inconvenient.
Summary of the invention
Existing flashlight illumination effect is poor in order to overcome, complex structure, use inconvenience, need the technical deficiency of periodic replacement battery, the flashlight that the purpose of this utility model is to provide a kind of and does not need battery, can generate electricity voluntarily and illumination effect is good.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with cylindrical shell, switch, illuminator, reflector and supply unit, the reflector front end is provided with light transmission piece, illuminator adopts the LED light emitting diode, supply unit is to be provided with permanent magnet in the coil, the input of coil two termination full-wave rectifying circuits, cross-over connection electrochemical capacitor between the output of rectification circuit, switch be connected in parallel on the electrochemical capacitor two ends after the LED light emitting diode is connected.Switch is made up of magnet and tongue tube.Light transmission piece is the optically focused convex lens.Cylindrical shell is provided with compass.
The beneficial effects of the utility model are, do not need battery, and the flashlight that rocks back and forth can generate electricity voluntarily, carry out energy storage by electrochemical capacitor, and illumination effect is good, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
1. supply units among the figure, 2. rectification circuit, 3. electrochemical capacitor, 4. illuminator, 5. switch.
