Abstract
An energy-saving electric torch comprises an LED lamp, an energy collection portion, an energy storage portion which is connected with the energy collection portion to store the collected energy, and a voltage conversion module which is connected with the energy storage portion to convert the voltage to a voltage appropriate for the work of the LED lamp and to provide the stable voltage for the LED lamp. The energy collection portion comprises a piezoelectric buzzer and a rectification circuit connected with the piezoelectric buzzer. Compared with the prior art, the energy-saving electric torch, which is light, simple and environmentally friendly, enables to achieve the aim of automatic charging by using the piezoelectric buzzer to collect the energy, with no need of special charging, and is excellent in energy saving and low in cost. By using a super capacitor to collect the energy, the more the energy is collected, the higher the density is, so that the luminescent time of the electric torch in use is longer.
Description
Technical field
The utility model relates to lighting technical field, particularly a kind of energy-saving flashlight.
Background technology
Flashlight commonly used at present generally uses battery as the energy supply device, realize illumination by powered battery, yet, make battery-powered flashlight need consume battery power, when the energy content of battery uses up, need change battery, be unfavorable for energy-conserving and environment-protective, and use inconvenient, the inconvenience that brings when avoiding using, not needing having occurred changing is the pond, but adopts kneading type or the manual powered flashlight of hand-rail type.Though yet this flashlight has solved the defective of using battery to exist, still has weak point, need carry out manual poweredly when it uses with hand or kneading, be inconvenient to use.
Summary of the invention
For addressing the above problem, main purpose of the present utility model is to provide a kind of do not have battery, light and handy, environmental protection and the convenient energy-saving flashlight that uses.
For realizing above purpose, the technical solution of the utility model is:
A kind of energy-saving flashlight; comprise collection of energy part, piezoelectric buzzer and the rectification circuit that is connected with piezoelectric buzzer; the energy storage area comprises capacitor and holding circuit; holding circuit is used to prevent that overvoltage from damaging capacitor; the energy storage area is used to connect the collection of energy part in order to store collected energy; the voltage transformation module connects the energy storage area to be the operating voltage that is fit to the LED lamp with voltage transformation, for the LED lamp provides burning voltage.
Described pressure buzzer is a kind of energy conversion device, when powering up on pressing buzzer, presses the buzzer vibration sounding; Otherwise when piezoelectric buzzer vibrated, piezoelectric buzzer just can output current, and promptly piezoelectric buzzer can become electric energy to the power conversion of mechanical oscillation.When people carry torch, self move the pressure buzzer vibration that causes in the torch, and then the output AC electric current.Change DC current into after the alternating current process rectification circuit rectification of pressing buzzer to produce, with input energy storage area.
Direct current input ultracapacitor through collection of energy rectification circuit rectification partly obtains charges to ultracapacitor.Though each charging current is less, accumulation gets up still capacitor to be full of.When using flashlight, the ultracapacitor output current, through the voltage of voltage transformation module converts for suitable LED lamp work, and play the purpose of burning voltage, the LED lamp is luminous more stable, described voltage transformation module is voltage transformation IC and accessory circuit, and the rectification circuit described in the present embodiment is a diode rectifier circuit.
The utility model energy-saving flashlight adopts the LED lamp luminous, and energy demand is few and luminous stable.Adopt piezoelectric buzzer harvest energy from vibration, the power conversion that mechanical oscillation are produced is an electric energy, and by the ultracapacitor stored energy, electric capacity releases energy when using flashlight.Flashlight is carried in the process, and human motion causes the piezoelectric buzzer vibration of flashlight, and when vibration frequency was mated with the piezoelectric buzzer vibration frequency, buzzer just can the output AC electric current, charges to electric capacity behind over commutation.During use, the voltage of capacitor output is powered to the LED lamp after overvoltage is through the conversion of voltage transformation module.Can realize that the LED lamp is bright.In order to increase the fluorescent lifetime of LED lamp, use ultracapacitor as energy storage device, can when not using torch, store more energy.
Compared to prior art, the utility model energy-saving flashlight utilizes the piezoelectric buzzer harvest energy to reach the purpose of automatic charging, need not special charging, and is lightly easy, and environmental protection and energy saving, cost are low; By utilizing the ultracapacitor harvest energy, harvest energy is many more, and density is big more, and fluorescent lifetime was longer when torch was used.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the utility model energy-saving flashlight
The specific embodiment
As shown in Figure 1; a kind of energy-saving flashlight; include the collection of energy part; the energy storage area; voltage transformation module and LED lamp; wherein; collection of energy partly comprises piezoelectric buzzer and the rectification circuit that is connected with piezoelectric buzzer; the energy storage area comprises ultracapacitor and holding circuit; holding circuit is used to prevent that overvoltage from damaging ultracapacitor; the energy storage area is used to connect the collection of energy part in order to store collected energy; the voltage transformation module connects the energy storage area to be the operating voltage that is fit to the LED lamp with voltage transformation, for the LED lamp provides burning voltage.
The utility model utilizes the piezoelectric buzzing harvest energy to reach the purpose of automatic charging, need not special charging, and is lightly easy.Environmental protection and energy saving, cost are low; By utilizing the ultracapacitor harvest energy, harvest energy is many, and density is big, and fluorescent lifetime was longer when flashlight used; And working voltage conversion IC makes LED luminous more stable.
Most preferred embodiment described above only is that the utility model is set forth and illustrated, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
