Electric appliance J1 is in obtain its control power input of electricity condition and the disconnection of normally-closed contact end, its control power input and normally opened contact
End closure, LED illumination lamp LEDN stops working shine after, due to the 3.9V of the 2 feet output of three ends are adjustable output voltage stabilizer U2
Power supply is communicated with relay J2 control power input this moment, the normally opened contact end of relay J2 and prompting mechanism micro buzzer-phone
B, the cathode power supply input terminal of LED illumination lamp LEDN is connected through conducting wire, 4 foot of cathode output end of regulated power supply ontology U1 and prompt
Mechanism micro buzzer-phone B, LED illumination lamp LEDN negative power supply input terminal connected through conducting wire, so micro buzzer-phone B meeting this moment
It is electric make a sound, LED illumination lamp LEDN can obtain electroluminescence, give user by micro buzzer-phone B sounding at the first time and mention
Show, carry out the investigation maintenance of failure in time, in order to avoid cause equipment overall failure to be magnified since long-time cannot repair, with
And after also breaking down after battery G illumination a period of time without electricity, the power output end 5 of regulated power supply ontology U1 and 4 feet, LED
Headlamp LEDN no longer shines and impacts to normal illumination, after LED illumination lamp LEDN obtains electroluminescence, it is therefore prevented that regulated power supply sheet
Body U1 is because the voltage that various failures cause its power output end 3 and 4 feet to export is got higher, LED illumination lamp LEDN can not work to week
Influence caused by ambient lighting is enclosed, and is guaranteed in a period of time, LED illumination lamp LEDN etc. can also work on, until battery G
Power consumption finish LED illumination lamp LEDN just stop shine (this mode is when LED light LEND is used as corridor emergency lighting
Especially effectively).
