Embodiment
The present invention is made up of five parts such as electro-optical package 1, condenser 2, pressurizer 3, battery indicator 4, casings 7.
Photo-electric conversion element commonly used is generally monocrystalline silicon piece, polysilicon solar battery slice or gallium arsenide film etc., and uses under large scale, as earthbound solar energy power station, spacecraft solar panel, roof solar cell panel, or the like.Can see from Fig. 2,3, electro-optical package 1 of the present invention is small and exquisite portable light electrical switching device, and the employing polysilicon solar battery slice is a photo-electric conversion element, cuts into only 3～20 millimeters fillet of width, be connected into assembly by bus 9, form through vacuum hotpressing.Spacing is 0.5～1.2 millimeter between the bar of polysilicon solar battery slice 1-1, and mutually insulated can produce 0.5-10 watt of electrical power under the AM1.5 illumination condition.
Can cause change in voltage when considering the electric quantity change of electro-optical package or condenser 2, constant in order to keep output voltage, adopt pressurizer 3 voltage stabilizings.Pressurizer 3 is three terminal regulator IC1, and voltage stabilized range is in 3～30 volts, and connecing needs to set, and output current is in 0.1～3.0 ampere of scope.
For the electric weight situation in the indication charge power supply, set up battery indicator 4, battery indicator 4 is green, red by oscillator and comparator circuit driving, yellow indicator lamp is indicated, or indicated with LCD.When using diode displaying, control red, green, yellow lamp with integrated oscillator, voltage comparator exclusive disjunction amplifier and show: the bright expression power supply of green light is normal; The bright expression electric weight of red light deficiency needs illumination immediately; The bright expression electric weight of amber light is full, should temporarily avoid illumination with anti-overcharge.When using liquid crystal display, with what of electric weight in the pattern displaying condenser.Diode D1, D2 among the figure plays the anti-reverse usefulness of useing as.
Start back (K1 closes a switch), when electric weight condenser 2 in is sufficient, the green light flicker, but illustrate that electrical appliance such as bio-occlusion mobile phone charges.Electric quantity consumption is to a half in condenser 2, and voltage comparator control red light is lighted, and prompting should be got sun to electro-optical package or the illumination charging at once.When electric weight was full of in the condenser 2, voltage comparator 6 control amber lights were bright, remind not overcharge.
In order to reduce battery indicator 4 power consumption of powdered, battery indicator 4 can arbitrarily open or close by K switch 2.The cycle of indicator light flicker was adjusted at about 0.7 second, and the duty time is longer than the glittering time.
Casing 7 of the present invention is of a size of: long 5～18 centimetres, wide 4～10 centimetres, high 1.5～4.0 centimetres; Long and wide front all is used for gathering luminous energy, area is fixing maybe can be changed by folding, pull, and for example electro-optical package adopts and divides body structure, is linked together by hinge at a side by the electro-optical package of two equidimensions, with further minimizing volume, but the enough miniature electrical equipments of power use.Each control switch and display unit are installed in the side, so that make full use of plane of illumination.
