Embodiment:

As shown in Figure 1, this multifunctional energy-saving lighting lamp, through filter rectifier, the one tunnel sends into (B) block diagram high frequency transformation output rectification circuit to civil power from the wide voltage of (A) block diagram input AC85-265V; (C) block diagram condition managing control model change-over circuit is sent on another road, sends into the output of (B) block diagram control stabilized voltage power supply again, sends into (D) block diagram charging automatic switching circuit; (E) block diagram solar charging power conversion circuit is sent into (D) block diagram charging automatic switching circuit, send into again (F) block diagram led circuit or (G) block diagram high pressure xenon gas lamp trigger the HID circuit for lamp.That whole light fixture has been realized is energy-efficient, having a power failure changes the stand-by power supply power supply automatically over to, and the many power supplys of solar energy annex the purpose of the multifunctional lamp of power supply.

As shown in Figure 2, the relevant circuit description of this multifunctional energy-saving lighting lamp:

1, civil power is by exchanging the Electromagnetic interference filter of end of incoming cables through inserting; form by common mode filtering coil L1 and C1, C2, C3, C4; C1, C2 and L1 are used to suppress common mode disturbances, C3 and C4 and are specifically designed to the filtering series mode interference; Rt1 is a thermistor; play the overheat protector effect; capacitor C 3, C4 cut off the power supply after Rt1 discharges, again through VD1-VD4, C6 rectification on the road.

2; export high direct voltage through the TR high frequency transformer through rectification; elementary protective circuit is by RC absorption circuit (C7; R2) and the short circuit (VS1 of clamper; VD5) constitute; can suppress the peak voltage that exists leakage inductance to produce because of high frequency transformer effectively; the internal switch pipe of protection IC1 is not damaged; C5 is the 1 pin Vcc shunt capacitance of IC1; the direct ground connection of R3; can improve the reliability of mode switch; 5 pin of the startup power supply of condition managing control model conversion IC 1 by IC1 provide operating voltage Vcc below the 10V for 1 pin of IC1; behind the circuit start; from the high frequency transformer secondary winding, can obtain normal output voltage; this moment, feedback coil NF life's work was powered to IC1; in case overload or short trouble take place in this power supply; the power switch pipe of IC1 inside just turn-offs; IC1 is inner then to work on for the metal-oxide-semiconductor field effect transistor that starts usefulness; IC1 enters automatic startup mode of operation; because the 2 pin short circuits of Vcc and IC1; 2 pin are the feedback signal input; it is the break-make of power controlling switching tube periodically; (feedback end on; threshold voltages is respectively 8.5V and 7.5V; the lagging voltage that 1V is arranged); obviously the VFB of chain type feedback voltage (IC1) has reflected the height of switch power source output voltage; the output voltage of feedback winding forms the feedback output voltage after high-frequency rectification and filtering; phototriode by IC2 is connected to feedback end again; (sampling voltage is through R5 to the transmitting tube of IC2 in the sample circuit because of being connected on; obtain after the R6 dividing potential drop), the signal of feedback winding is through R1; C5 ground connection.C8 has three effects: at first it is the timing capacitor of start-up circuit; Secondly with R3 feedback control loop is compensated; Still the shunt capacitance of working power voltage Vcc by C5 is charged, is set up Vcc voltage in start-up course, accurate shunt regulator IC3 constitutes the external error amplifier, connect with IC2, form photoelectricity coupling chain type negative-feedback circuit, feedback voltage V FB is added to feedback end 2 pin of IC1.Its principle of stabilized voltage is, when fluctuation takes place in output voltage, after R5, R6 dividing potential drop, obtain sampling voltage and compare with reference voltage among the IC3, produce external error voltage, by IC2, make feedback current IFB produce feedback voltage V FB again, both compare, and regulate output duty cycle with this, reach the purpose of the wide voltage input of AC DC voltage stabilizing output.

3, again will be by the voltage of DC power supply through about VD9 generation 15V of voltage stabilizing, one the tunnel as charge power supply, supply with charging and control circuit, another road indicates VL1 to light power supply, VS2 ends when storage battery GB1 voltage is less than or equal to 13V, the V1 conducting, the high level pulse of its collector electrode output passes through C15, the gate pole of VT2 adds a triggering level, makes the VT2 conducting, and GB1 begins charging, charging indication VL2 lights, VT1, VS2 and VD11 are in cut-off state, and when GB1 was charged to the 13.5V left and right sides, VS2 punctured conducting, V1 is instead ended partially, the VD11 conducting is triggered and conducting VT1, and the electric charge that is filled on the C15 is added in by VT1 on the negative electrode of VT2, and VT2 is ended because of the instantaneous reverse voltage that adds, VL2 extinguishes, and charging finishes.Automatically change by VD10, K if having a power failure, from the constant normal power supply of storage battery GB1.

4, the solar energy converting circuit is by V2, IC4, solar battery group, elements such as GB2 are formed, circuit core is that IC4 contains an amplifier and a reference power supply because of it, again by R15, the feedback loop divider that R16 forms is used for detecting cell voltage, internal reference voltage GB2 (200mAV) is amplified to 7.5V to circuit and feedback voltage is made comparisons, the effect of thermistor RT2 is the charging voltage of accurate tracking battery in wider temperature range, the variations in temperature of balancing battery, when GB1 is charged to 14.1V, amplifier output begins to rise, the conducting of V2 pipe is overcharged preventing, supply voltage is divided equally on V2 pipe and R17 resistance.Power for LED circuit for lamp and the HID circuit for lamp in the block diagram (G) in the block diagram (F) by (D) block diagram charging automatic switching circuit then.

Above brief description be exactly the wide voltage of AC85-265 by filter rectification, condition managing pattern change automatically, the rectification of high frequency transformation, solar recharging conversion, charging automatically conversion directly give the overall process of LED lamp or HID lamp power supply.
