Abstract
The utility model relates to an illuminating device which comprises a power supply T<3>, an outer housing and an electric bulb L. The multifunctional flashlight additionally comprises an induction type alarming device which is, together with the electric bulb L, connected with the power supply T<3> through a change-over switch K<1>. The flashlight can be used as an electric torch for normal use. As an alarm, the utility model can be hung on the door lock in a house for sending out sound to alarm when a visitor contacts or approaches the door lock outside of the door. When someone is in the house, the change-over switch of the utility model can be shifted to the position of a doorbell to send out doorbell sound in case that someone else contacts or approaches the door lock outside of the door. The multifunctional flashlight which has convenient operation omits the trouble of installing doorbells and alarms.
Description
The utility model relates to a kind of lighting device.
Torch of the prior art is made up of shell, battery, switch and bulb, has only single illuminating effect.
The purpose of this utility model is to provide a kind of multifunctional electric torch that can be used as the usefulness of illumination, doorbell, alarm.
The technical solution of the utility model is: the utility model comprises power supply T3, shell and bulb L, and in addition, it also comprises an induction type warning device, and bulb L is connected with power supply T3 by change-over switch K1 with the induction type warning device.When upwards stirring K1, can make the power connection bulb, make bulb bright; When stirring K1 downwards, can make power connection induction type warning device, make warning device send the sound, warning device can send " ding-dong " doorbell sound or sharp-pointed buzzing chimes of doom.
The induction type warning device comprise oscillator, the oscillator signal of oscillator output be converted to dc signal wave detector, the signal of telecommunication of wave detector output is carried out signal amplify and export the amplifier of a level signal, drive circuit, loudspeaker through triggering the signal generator that can produce alarm signal, the signal of signal generator output being carried out power amplification.When human body during near the induction antenna on the oscillator, the oscillatory regime of oscillator takes place, and loudspeaker just can send doorbell sound or chimes of doom, and doorbell sound or chimes of doom produce signal by signal generator.
The utility model compared with prior art has following advantage:
Just often, can be used as torch and use, when using, the utility model can be hung within doors on the door lock, if there is the people contacting outdoors or during near door lock, the utility model can send audible alarm as alarm; As the people is arranged within doors, switch of the present utility model can be dialled in the doorbell position, the people is arranged in contact outdoors or during this moment near door lock, can send doorbell sound; This device is easy to use, has removed the trouble that doorbell, alarm are installed from.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is circuit theory diagrams of the present utility model;
Accompanying drawing 2 is the circuit block diagram of induction type alarm of the present utility model;
Embodiment: the utility model comprises power supply T3, shell and bulb L, and it also comprises an induction type warning device, and bulb L is connected with power supply T3 by change-over switch K1 with the induction type warning device.Referring to accompanying drawing 2, the induction type warning device comprise oscillator 1, the oscillator signal of oscillator 1 output be converted to dc signal wave detector 2, the signal of telecommunication of wave detector 2 outputs is carried out signal amplify and export the amplifier 3 of a level signal, drive circuit 5, loudspeaker 6 through triggering the signal generator 4 that can produce alarm signal, the signal of signal generator 4 outputs being carried out power amplification.Referring to accompanying drawing 1, power supply T3 provides power supply by change-over switch K1 for the induction type warning device of bulb L or below; BG1 forms high-frequency generator by high-frequency triode, and frequency of oscillation is connected to antenna T1 by inductance coil L1, capacitor C 1 decision of parallel connection on the inductance L 1; Capacitor C 3 is a coupling capacitance, diode D1 carries out halfwave rectifier (playing wave detector 2), and triode BG2 is used for signal and amplifies, and the signal after 4 pairs of detections of capacitor C carries out filtering, triode BG3 carries out one-level again and amplifies, triode BG4 is as switch triode, and when oscillator 1 normal vibration, the BG3 base stage is a high level, the BG4 base stage is a low level, not conducting of BG4, IC1 is not triggered so do not work yet, and loudspeaker T2 does not sound.The model of ic chip 1 is KD-254, and K switch 2 can be dialled at S1(doorbell sound), the S2(buzzer), the S3(musical sound) arbitrary shelves on three shelves, VDD is a power end, VSS is an earth terminal.The signal that BG5 produces signal generator 4 carries out sending back grade loudspeaker T2 after the power amplification, in order to increase the sound of loudspeaker, is connected to the auto-transformer B of supercharging between drive circuit 5 and the loudspeaker 6, makes the T2 loudspeaker can obtain bigger signal.When human body during near antenna T1, the blocking of oscillator or vibration damping, the BG3 base stage obtains low level, and BG3 ends, and the BG4 base stage is a high level, and the BG4 conducting triggers IC1 by K2, produces signal and send loudspeaker T2 to send the sound through drive circuit 5.
