Abstract
The utility model relates to an illumination lamp, in particular to an automatic-control illumination lamp of a telephone. After being in series connected with a normal-open contact K1 of a relay K, an illumination lamp ZD is connected with a power supply plug S in parallel. Through the voltage reduction of C4, the rectification of diodes D7 and D8, the filtration of a capacitor C3, and the voltage stabilization of a voltage stabilizing diode DW, an external power supply provides work voltage to a time-base integrated circuit IC2. Leading wires L1 and L2 of a telephone socket Z are connected with a pin 1 and a pin 2 of an optical coupler IC1 in parallel through a capacitor C1 and a resistor R1. Diodes D2, D3, D4 and D5 form bridge-type rectification to ensure the upper positive electric polarity and the lower negative electric polarity of the output voltage without considering the change of the polarity of the connection of L1, L2 and the telephone. When a call of the exterior line comes at night, and after the voltage reduction of C1 and the current limitation of R1, a ringing signal conducts the optical coupler IC1, the relay K works, the normal-open contact is closed, and the illumination lamp ZD is turned on. The illumination lamp automatically turns on when a call comes or the user calls the others at night, and automatically turns off after use.

Bridge rectifier is connected with diode D6 by be made of bleeder circuit R2 and R3, and diode D6 is connected with the 2nd pin of time-base integrated circuit IC2.
The model of described photo-coupler IC1 is 4N25.
The model of described time-base integrated circuit IC2 is NE555.
The model of described relay K is 4098.
The model of described triode T1 is a NPN type triode 9014.
The model of described phototriode T2 is 3UD5.
During use, L1, L2 are connected with external telephone wire, the plug of Telephone set inserts in the telephone socket Z, attaching plug S is inserted in the supply socket of 220V the debugging of can switching on, during debugging, with the 2nd pin ground connection of a lead, regulate W1 the lamp of relay control is extinguished, afterwards earlier IC2, live phototriode with stick shift, bulb should be lighted.Remove the earth connection of IC2, live phototriode with stick shift again, take telephone microphone, illuminating lamp should be lighted.If illuminating lamp can not be lighted, should suitably reduce the resistance of R3, till illumination lamp ignition.
Operation principle of the present utility model is as follows:
In circuit, external power supply passes through the C4 step-down, diode D7 and D8 rectification, and capacitor C 3 filtering, Zener diode DW voltage stabilizing provides stable+6V operating voltage then to time-base integrated circuit IC2.L1 and L2 are in parallel with telephone wire, and diode D2-D5 forms bridge rectifier, and purpose is to guarantee the how conversion of polarity that no matter L1, L2 are connected with phone, and the polarity of its output voltage is negative just down on being all the time.
During the phone on-hook, the voltage between L1, L2 two ends oppositely ends diode D6 after R2, R3 dividing potential drop, and the 2nd pin of IC2 is high level, 3 pin output low levels at this moment, and relay K is failure to actuate.
When outside line has phone to call in the night, the 90V that switch is sent here, the bell signal of 25HZ, after capacitor C 1 step-down, resistance R 1 current limliting, light emitting diode among the photo-coupler IC1 is lighted, and the phototriode conducting draws the 2nd pin of IC2 to be low level, at this moment the 3rd pin of IC2 output high level, the relay K action, normally opened contact K1 closure, illuminating lamp ZD lights; Meanwhile, the triode conducting over the ground of IC2 the 7th pin inside, capacitor C 6 is discharged rapidly, at this moment, user's off-hook is listened to phone, and line voltage distribution is dropped to below the 12V by 40-60V, and the R3 dividing potential drop drops to about 1V, diode D6 conducting, the 2nd pin of IC2 is clamped at about 1.7V, and during the user's communication, IC2 the 2nd pin keeps level always, be lower than 1/3Vcc, then illuminating lamp ZD lights all the time.On-hook after energising finishes, L1, L2 recover the 40-60V normal voltage again, and D6 oppositely ends again, and the 2nd of IC2 becomes high level, and the triode of the 7th pin inside ends over the ground, and IC2 enters temporary stable state.Along with power supply constantly charges to electric capacity through R5, through 1.1R5 * C6 time, about 24 seconds, the C5 both end voltage rose to 1/3Vcc, and the 3rd pin of IC2 becomes low level, and the relay K dead electricity discharges, and normally opened contact K1 opens, and illuminating lamp extinguishes.
When the user called night, operation principle was same as described above, and illuminating lamp is also lighted automatically, and end of conversation extinguished in about 24 seconds automatically.
Daytime, constitute the light testing circuit by resistance R 6, W1, phototriode T2 and triode T1, because resistance diminished after phototriode was subjected to illumination, make triode T1 conducting, the 4th pin of IC2 is low level, forces IC2 to be in reset mode, therefore, the 3rd pin of IC2 is always low level, so no matter answer or call daytime, illuminating lamp is not lighted all the time.
