Description

There is the desk lamp of host and guest's recognition function

Technical field

The present invention relates to a kind of desk lamp, be specifically related to a kind of desk lamp with host and guest's recognition function.

Background technology

Desk lamp is a kind of light fixture of convenient read-write, the primary structure of desk lamp comprises lamp holder, for covering the lampshade of lamp holder, fluorescent tube that upper end is connected with lampshade, the lamp socket that is connected with fluorescent tube lower end, current desk lamp, some conveniently regulates the angle of lamp holder, fluorescent tube often adopts metal bellows, and what current desk lamp was pursued mostly is the elegant in appearance of profile, and function is more single.Doorbell in modern house is all mounted on door, and when messenger presses doorbell, the people on one's own side or guest cannot be differentiated, design inadequate hommization, reasonability is poor, and when people are in rest at night, likely Problems existing is, when there being naughty child to press doorbell by mistake, heavy sleeper can being alarmed, affect people's.

Summary of the invention

The invention is intended to provide a kind of desk lamp with host and guest's recognition function, there is energy-conservation effect simultaneously.

The desk lamp with host and guest's recognition function in this programme, comprise lamp holder, for covering the lampshade of the one end open of lamp holder, for installing the pedestal of lamp holder, the fluorescent tube that upper end is connected with pedestal, the lamp socket be connected with fluorescent tube lower end, described lamp socket is provided with lamp holder switch, described lamp holder switch is connected on the loop of lamp holder, the loop of described lamp holder is also connected with relay, also comprise the host and guest's alert circuit be arranged in pedestal, described host and guest's alert circuit comprises transmitter module and receiver module, the first resistance that described transmitter module comprises multivibrator and is connected with multivibrator output, first resistance is linked into the input of emitting module, the normally-closed contact of relay is linked in transmitter module for controlling the keying of transmitter module, the first button is also provided with at transmitter module, described first button is arranged on outdoors, described receiver module comprise with emitting module with the use of receiving unit, the decoder be connected with the output of receiving unit and the music trigger triggered by decoder low level, the second button is provided with at the high level trigger end of music trigger, described second button is arranged on outdoors, the output of described music trigger is connected with loudspeaker, the key switch be simultaneously also provided with on the circuit of the second button of receiver module, key switch is arranged on lamp socket.

Operation principle and the beneficial effect of the present invention program are as follows: during daytime, often I have a visit from a guest in meeting, therefore the key switch be connected on receiver module is closed, and daytime also can not use desk lamp simultaneously, and the normally-closed contact being therefore positioned at the relay on transmitter module is also adhesive.

When the people on one's own side stands outside the door, when needing within doors other people to open the door, press the first button, transmitter module live line work, multivibrator starting of oscillation, its signal exported delivers to the input of emitting module through the first resistance, modulated and launch by emitting module.The signal that receiving unit receiving demodulation goes out is delivered to decoder and is carried out decoding, when the centre frequency of decoder is equal with the modulating frequency of transmitter module, decoder output low level, trigger music trigger, music trigger exports ding-dong acoustical signal, and through loudspeaker sounding, remind people to be within doors that the people on one's own side has returned.

When guest stands outside the door, press the second button, transmitter module dead electricity does not work, and the high level trigger end of music trigger triggers, and exports chirm signal, and through loudspeaker sounding, reminds people to be within doors that guest has arrived.

During night, in order to prevent bothering, people can the key switch that be connected on the second button circuit disconnect, and also can not sound alarm people within doors even if there is stranger to press the second button by mistake.

And when people are when opening desk lamp reading night, the relay be connected on lamp holder loop obtains electric, the normally-closed contact of relay disconnects, and transmitter module is inoperative, even the people on one's own side also can not sound and alarms people within doors because pressing the first button.

When people close desk lamp, when closing the key switch be connected on the second button circuit simultaneously, transmitter module is work, people within doors can be reminded to open the door when the people on one's own side presses the first button, stranger presses the second button and does not then have prompting sound, and namely when night, this prompting function is only opened household, and guest or stranger are closed, avoid unnecessary bothering.

Further, the circuit of decoder is also connected with the adjustable potentiometer for regulating this decoder centre frequency.For regulating the centre frequency of decoder, when the centre frequency of decoder is equal with the modulating frequency of transmitter module, decoder low level triggers music trigger.

Further, between music trigger and loudspeaker, transistor amplifier is connected with.Voice signal is played to the effect of amplification.

Further, fluorescent tube adopts telescope structure.By regulating the height of fluorescent tube, and then the distance of adjustable desk lamp light and human eye, make light more moderate.

Further, lamp socket is column, and described lamp socket has at least two vertical resettlement grooves along the circumference of lamp socket.Function of desk lamp variation, can place pen or cup in resettlement groove.

Further, openable cover cap is provided with in the outside of described first button.Prevent guest and stranger from pressing the first button, and guest or stranger are treated as the people on one's own side by mistake.
