(2) background technology
Up to now, at home and abroad comparatively common traditional photophore (as flashlight and emergency light etc.) has two kinds on the market: 1) utilizing dry cell that the energy is provided, is light-emitting component with the incandescent lamp; 2) utilizing chargeable battery to be the energy, is light-emitting component with the incandescent lamp, and line bonus from or the integrated form charger.
Use traditional photophore of dry cell that following shortcomings are arranged: dry cell relies on chemical reaction work, uses and the energy storage time weak point; Need frequent replacing, secondary consumption costs height; Can not be in extreme temperature (too high or too low) work down; Very easily cause housing corrosion or unexpected flow liquid to damage, or break easily, shorten photophore service life (general 1～2 year) because of bad mechanical strength because of battery makes moist; Have mechanical part, the corrosion that gets rusty easily causes loose contact, uses problems such as trouble, and a large amount of old and useless battery environmental pollutions are on the rise, and harm humans health has recycled into a great society problem.
Chargeable battery formula photophore, though need extra or integrated charging equipment and charging expense the service life of the limited prolongation battery of energy, cost is higher.Whenever live through simultaneously once charging, the energy storage capacity of chargeable battery will descend, and its charging life-span generally has only 50～200 times.Photophore also can often be scrapped because of the aging or damage of rechargeable battery.
Secondly, the used incandescent lamp bulb of traditional photophore is the electric current that utilizes battery the to provide osram of flowing through, and it is generated heat to uniform temperature and luminous.The luminous efficiency of incandescent lamp bulb is extremely low, generally has only 5%～10% electric energy to be converted into luminous energy, and remaining most electric energy become radiativity heat energy and slattern.Fragile tungsten filament more is subject to foreign impacts power (as dropping on the ground) and ruptures.Generally be less than 500h the service life of incandescent lamp bulb, and it is scrapped through being everlasting before burning out naturally because of fracture.
(3) summary of the invention
The utility model aims to provide a kind of efficiency for charge-discharge and luminous intensity height, puts effectively that to fill time scale big, adopts the regeneration of mechanical energy-magnetic energy-electric energy-transform light energy to exempt from the portable magnetic energy environment friendly photophore of battery.
