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, realizes illumination by powered battery.Yet, make battery-powered flashlight need the energy of consuming cells, when using up, the energy content of battery need change battery, and be unfavorable for energy-conserving and environment-protective, and use inconvenient.Battery not needing to have appearred in the inconvenience for avoiding using battery to bring, but adopts kneading type or the manual powered flashlight of hand-rail type.Yet, though this flashlight has solved the defective of using battery to exist, still there is weak point, need carry out manual poweredly when it uses with hand or kneading, be inconvenient to use, and hand frame for movement heaviness, unreliable.This is for motion exploration personnel, night homecoming person, and the special duty personnel still are inconvenient to use.
[utility model content]
For addressing the above problem, main purpose of the present utility model is to provide a kind of no battery, light and handy, environmental protection, and the convenient energy-saving flashlight that uses.
For achieving the above object, the technical solution of the utility model is:
A kind of energy-saving flashlight, include LED lamp, collection of energy part, connect the collection of energy part in order to the energy storage area of storing collected energy, connect the energy storage area with voltage transformation for being fit to the LED light working voltage, and provide the voltage transformation module of burning voltage for the LED lamp; The rectification circuit that described collection of energy partly includes piezoelectric buzzer and is connected with piezoelectric buzzer.
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, and density is big, and fluorescent lifetime was longer when torch was used.
[description of drawings]
Fig. 1 is the theory diagram of the utility model energy-saving flashlight.
[specific embodiment]
See also shown in Figure 1, a kind of energy-saving flashlight of the utility model, include LED lamp, collection of energy part, connect the collection of energy part in order to the energy storage area of storing collected energy, connect the energy storage area with voltage transformation for being fit to the LED light working voltage, and provide the voltage transformation module of burning voltage for the LED lamp.
The rectification circuit that described collection of energy partly includes piezoelectric buzzer and is connected with piezoelectric buzzer.Piezoelectric buzzer is a kind of energy conversion device, when on piezoelectric buzzer, powering up, and the piezoelectric 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 carried torch, displacement caused the piezoelectric buzzer vibration in the torch, and then the output AC electric current.Change DC current into after the alternating current process rectification circuit rectification that piezoelectric buzzer produces, with input energy storage area.
The energy storage area mainly includes ultracapacitor and prevents that overvoltage from damaging ultracapacitor, the holding circuit of protection ultracapacitor.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 is the voltage that is fit to LED work through the voltage transformation module converts, and plays the purpose of burning voltage, makes LED luminous more stable.Described voltage transformation module is voltage transformation IC and accessory circuit.Rectification circuit described in the present embodiment is a diode rectifier circuit.
The utility model energy-saving flashlight adopts LED 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, the motion of human body causes the piezoelectric buzzer vibration in the flashlight, and when vibration frequency was mated with the piezoelectric buzzer resonant frequency, buzzer just can the output AC electric current, behind over commutation, charge to electric capacity, can be in capacitor with power storage.Therefore, a very important person is in motion at ordinary times, and flashlight just can charge automatically.During use, to the LED power supply, can realize that the LED lamp is bright after the voltage process voltage transformation module conversion of capacitor output.In order to increase the fluorescent lifetime of LED lamp, use ultracapacitor as energy storage device, can when not using torch, store more energy.
This creation 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, and density is big, and fluorescent lifetime was longer when torch was 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.
