Description

The multi-function telephones lamp

Technical field

The invention belongs to the electron controls technology field, relate to a kind of multi-function telephones lamp.

Background technology

At present, nearly all fixed telephone has only the incoming call ringer function on the market, in addition other call reminding modes never again.A lot of people had such cognition, be exactly that the family expenses fixed telephone often runs into the darker condition of light and need call,, have to turn on electric light specially during dialing because of not seeing the key number on the telephone set, be exactly the not good enough people of hearing in addition, use black phone very inconvenient.Phone and electric light organically can be combined, to solve phone lighting problem in use.Of the present invention is exactly to utilize telephone line, telephone set, incandescent lamp and a little electrons element, has effectively solved illumination and some other relevant issues when phone uses.

For effectively solving the technical problem of this respect, on the basis that does not change original telephone set network and structure, the multiple scheme of process is tested, is analyzed and relatively, realized intended purposes with a small amount of components and parts.

This multi-function telephones lamp of the present invention mainly contains following multiple practical use, below describes the correlation technique that this multi-function telephones lamp is made in detail.

Summary of the invention

Goal of the invention and multiple use

1. telephone set dialing illumination: electric light is promptly lighted behind the phone off-hook, can be used as telephone set dialing illumination.

2. remind the on-hook function: made a call and put back to receiver,, illustrated that the receiver of telephone set is not put back to original position, in time reminded the correct on-hook of user if electric light does not extinguish.

3. the prompting of calling: most old men are hard of hearing may not to hear the ringing tone of calling sometimes, particularly live under roadside or the noisy environment, more likely can't hear the ringing tone of telephone set and miss phone, when seeing that electric light is when glittering discontinuously, learnt that promptly phone calls in, can effectively avoid missed call.

4. telephone set can install the ringing tone switch additional: close the ring loudspeaker of telephone set, can be interrupted glittering prompting with electric light has phone to come in, and can effectively exempt bothering the household that having a rest or infant or to the easily terrified patient of ringing tone.

5. free call on sb. else's expense through illegal means caution and outside line broken string prompting: electric light is lighted if find oneself not have the people to make a phone call, and can mention phone transmitter to listen to, if hear that people's conversation sound is arranged, someone's circuit of usurping that a phone call for you is described; If no any sound in the receiver illustrates the outside line broken string, can in time notify telephone office's maintenance telephone circuit.

Technical characterictic: the multi-function telephones lamp, it comprises telephone line full-bridge rectification and voltage stabilizing circuit, photoelectrical coupler, one-way SCR circuits for triggering, civil power halfwave rectifier filter circuit, one-way SCR load circuit, it is characterized in that:

Operation principle:

When phone not during off-hook, the voltage at telephone line L1, L2 two ends is 40～48V, after the D1～full-bridge rectification of D4 diode composition, the step-down of resistance R 1, voltage stabilizing didoe DW voltage stabilizing, obtain the direct voltage of 12～15V, this voltage makes the lumination of light emitting diode in the photoelectrical coupler (G1), cause the phototriode conducting in the photoelectrical coupler (G1), at this moment the current potential that triggers resistance R 3 two ends is near 0V, make the control utmost point triggerless voltage of one-way SCR (VT), the two ends no-voltage of the incandescent lamp (HL) in one-way SCR (VT) load circuit and not working.When the telephone set off-hook, the voltage at telephone line service wire L1, L2 two ends drops to 8～10V, (DW) can not get puncture voltage because of voltage stabilizing didoe, be added in 1 pin of photoelectrical coupler (G1), the voltage between 2 pin is lower than 1V, the phototriode in the photoelectrical coupler (G1) because of unglazed photograph by.The 220V civil power is through the filtered direct voltage of resistance R 4 step-downs, silicon rectifier diode (D5) halfwave rectifier and capacitor C 1, again by after the divider resistance R2 dividing potential drop, the two ends of triggering resistance R 3 can obtain the above voltage of 10V, at this moment the control utmost point of one-way SCR (VT) obtains trigger voltage and makes one-way SCR (VT) conducting, and the incandescent lamp (HL) in its loop is lighted.
