Abstract
The utility model discloses a mobile storage device with supercapacitor emergency lighting function, which comprises a shell, a mobile storage device, an electrical storage device, a lighting device and a lighting switch, wherein the electrical storage device adopts a supercapacitor, and the lightening device adopts a light-emitting diode with low power consumption, high brightness and long service life; in the shell (6), the positive electrode of the USB interface of the mobile storage device (5) is connected with the positive electrode of the supercapacitor C (2) through a diode D1 (1), and the positive electrode of the supercapacitor C (2) is connected with the positive electrode of the light-emitting diode D2 (4) through the lighting switch S1 (3); and all negative electrodes are communicated to be grounded. When the mobile storage device is connected with the USB interface of a computer, the power supply of the USB interface of the computer starts to charge the built-in supercapacitor, and when the mobile storage device is disconnected with the USB interface of the computer, the lighting switch is pressed, the supercapacitor starts to supply power to the light-emitting diode for lighting, and then light-emitting diode emits light so as to meet the emergency lighting in offices and daily life. The utility model has the characteristics of small size, simple structure, environmental protection, convenience and practicality, long service life and the like.
Description
Technical field:
The utility model relates to a kind of movable storage device that uses the super capacitor function of emergency illumination.
Background technology:
Movable storage device have convenient small and exquisite, memory space big, highly versatile, characteristics such as portable, is the most frequently used storage medium of current office, almost most of computed people have one or several movable storage devices.At present, the movable storage device major function of selling on the market also has some movable storage devices to have sound, video playback capability except the storage data, and some also has illumination functions.In the modern handle official bussiness process, can run into the sudden power phenomenon, need emergency lighting to close consumer.
The illuminating little torch of people uses zinc-manganse dioxide dry cell, Ni-MH Ni-Cd rechargeable batterie, chargeable lithium battery that electric energy is provided mostly.Zinc-manganse dioxide dry cell is disposable use, can not recycle, and causes environmental pollution.Though and rechargeable battery can be recycled, need complicated charging circuit, could guarantee its life-span at 500-1000 time, the overdischarge of overcharging all can cause battery to damage, even sets off an explosion or fire.
Super capacitor, charging rate is fast, and it is long to recycle the life-span, and degree of depth charge and discharge cycles access times can reach 400,000 times, do not have " memory effect "; The product starting material constitute, produce, use, store and disassemble process all less than polluting, and are ideal green environmental protection power supplys; It is simple to discharge and recharge circuit, need not the such charging circuit of rechargeable battery, and the safety coefficient height uses non-maintaining for a long time.
Summary of the invention:
At the office process sudden power, need illumination to close consumer and other need the occasion of emergency lighting, existing light fixture uses battery to have pollution problems, and the utility model provides a kind of movable storage device that uses the super capacitor function of emergency illumination.
The technical scheme of the movable storage device of the utility model super capacitor function of emergency illumination is: it comprises shell, movable storage device, electrical storage device, lighting device, light switch.Electrical storage device adopts super capacitor, and lighting device adopts the light emitting diode that power consumption is little, brightness is high, the life-span is long.In the shell, the USB interface positive pole of movable storage device is received the positive pole of super capacitor C by diode D1, and the positive pole of super capacitor C is connected to the positive pole of LED for illumination D2 by light switch S1, and all negative poles are communicated with ground connection.Principle of work is: when movable storage device was connected with computer USB interface, the computer USB interface power supply began to utilize the diode unilateral conduction for built-in super capacitor charging, and positive source seals in diode, makes electric current way flow go into super electric capacity.When disconnection is connected with computer USB interface, press light switch, super capacitor begins to the illumination light-emitting diode power supply light emitting, satisfies the daily life emergency lighting and uses.
The beneficial effects of the utility model are: do not influence the operate as normal of movable storage device, charging circuit that need not be complicated, electrical energy storage device environmental protection, life-span long (the super capacitor repeated charge can reach 400,000 times).Overall volume is little, in light weight, convenient and practical.
