Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1-Fig. 2, the multi-function emergency LED bulb of this band back-up source, it comprises CC-CV control circuit, battery charge/discharge protection circuit, battery, charged state display module, UPS Digital Detecting control circuit, LED light adjusting circuit and LED light emitting source; Described UPS Digital Detecting control circuit is connected with CC-CV control circuit, battery charge/discharge protection circuit, battery, LED light adjusting circuit; CC-CV control circuit, battery charging and discharging road, battery, charged state display module connect successively; LED light adjusting circuit is connected with LED light emitting source, and CC-CV control circuit is electrically connected with city.
CC-CV control circuit comprises current rectifying and wave filtering circuit, transformer T1 and the IC1 for constant current, Isobarically Control.Described battery charge/discharge protection circuit and charged state display module comprise for the discharge and recharge of battery and the IC3 of battery charging state display.
Charged state display module also comprise display battery charging indicator lamp LED1, display battery be full of electricity indicator lamp LED2.
UPS Digital Detecting control circuit comprises the IC2 whether having electricity, civil power break-make for detecting civil power, open and close function of emergency illumination, open and close temporary lighting function, IC2 is made up of (being followed successively by ic2-1, ic2-2, ic2-3, ic2-4 and ic2-5) 5 not gates, in this circuit, the A point of IC2 not gate input is electrically connected with the one end being connected civil power through diode D1, resistance R1, and in circuit, GND end is connected with the other end of civil power through resistance R2.
LED light adjusting circuit is electrically connected with the negative pole end of LED light emitting source, and the positive terminal of LED light emitting source is connected with UPS Digital Detecting control circuit by triode Q3.
Battery is lithium polymer battery.
The input of current rectifying and wave filtering circuit is electrically connected with civil power; elementary coiling group, the IC1 of output and transformer T1 are electrically connected; to form CC-CV control circuit; civil power is become to become DC5V2A dc source (the secondary rolling thread group of transformer T1 exports) by this circuit; 5V dc source divides 2 tunnels; one tunnel is charging use, and namely enter IC3 the 1st pin for battery charge/discharge protection circuit and charged state display module, another road is used for LED light emitting source.
After 5V power supply enters IC3 the 1st pin, export contact resistance R14 through the 3rd pin and regulate charging current, 4th pin is that charge power supply exports, the electric current exported directly enters battery VCC and holds, when battery is lower than 4.2V, IC3 opens charging in inside automatically, and the transmission of electricity of IC3 the 4th pin is held to battery VCC, when battery-end electricity reaches 4.2V, charging circuit stops charging.Whether charged state display module display battery is full of electricity, and IC3 the 2nd pin connects indicator lamp LED1, and the 6th pin connects indicator lamp LED2.During charging, IC3 the 2nd pin has high level output, and indicator lamp LED1 is bright; When being full of electricity, IC3 the 2nd pin high level becomes low level, and the 6th pin low level becomes high level, indicator lamp LED2 bright light, to illustrate that battery is full of electricity.When civil power has electricity, the whether full electricity of battery charge/discharge protection circuit self-measuring battery, makes the electricity of battery be in optimum state, ensures the service life of battery.
