Adopt the high-power White LED of 1W to make illuminating source, and have high light and the low light level selective, high light is lit a lamp and is reached 1h, and the low light level is lit a lamp and reached 2h, and the working life of LED reaches 50000h.
Referring to Fig. 2, the charging of super electrode capacitance is by switch-type voltage-dropping IC 3, inductance L 1, diode D2, capacitor C 4, C5, C6, C3, C7, C8, resistance R 10, R11 etc. form the switch-type voltage-dropping circuit, DC12V reduces to stable DC6.2V (2A with input, reach 3.5A in short-term) again through diode D1 step-down 0.7V, output 5.5VDC charges to super electrode capacitance C1+C2, and having limited super electrode capacitance both end voltage simultaneously can off-rating.
The indication of charging process is as follows:
Preestablish the numerical value of half adjustable resistance VR1, when " A " point voltage during less than DC6.0V (" B " point voltage is less than DC5.3V) LED2 long bright; As " A " when voltage rises to DC6.0V (" B " point voltage is higher than DC5.3V), it is glittering that LED2 changes.
Voltage detecting circuit is by adjustable integrated regulator IC2, half adjustable resistance VR1, resistance R 8, R9, R6, R7, triode Q2 form, when " A " point voltage during less than DC6V, not conducting of IC2, Q2 ends, and IC1 does not work, and this moment, Q1 obtained biasing and conducting by R4, LED2 lights, and R3 is the current-limiting resistance of LED2.
When " A " point voltage rises to more than the DC6V, the IC2 conducting, Q2 obtains " just " biasing through R7, and positive supply to IC1 (LED flashing light 1C) power supply, is stabilized in 3.6V by ZD1 through R5, makes LED2 glittering by long bright change by Q1, indicates super electrode capacitance charged basically.
The drive circuit of high-powered LED lamp: when change-over switch SW1 cuts to high light (H1GH) point, super electrode capacitance has stored electric charge and has discharged to LED1 through R2, operating current 300～350mA.
When change-over switch SW1 cuts to the low light level (NORMAL) point, super electrode capacitance has stored electric charge and has discharged to LED1 through R1 and R2 series circuit, the about 150～180mA of operating current.
