Description

Remote-control desk lamp

The utility model belongs to a kind of desk lamp.

Existing desk lamp does not generally possess distant control function.Like this, needing under the situation of remote control certain inconvenience is arranged.In addition, existing lamp dimmer generally all adopts the rotary light adjustment knob, also have use to touch to carry out light modulation, but general utility functions is all more single.

The purpose of this utility model is to provide a kind of desk lamp that can remote control light modulating.

Its technical scheme is: a kind of Remote-control desk lamp, comprise lamp socket and lamp, and remote control is housed in the lamp socket, civil power is by capacitor C in the remote control circuit ₁Step-down, diode D ₁, D ₂Rectification, capacitor C ₂Filtering, voltage-stabiliser tube D ₃Voltage stabilizing is pressed for circuit provides galvanic current, and of the present utility model being characterised in that: acoustic frequency sensor meets amplifying triode BG ₁Base stage, its emitter connects by inductance L, capacitor C ₇The frequency-selective network that composes in parallel, the output of frequency-selective network meets triode BG ₂, triode BG ₂Collector electrode through capacitor C ₆, resistance R ₄The differential circuit of forming connects the triggering pin of pressure regulation integrated package, and its output pin connects the trigger electrode of bidirectional triode thyristor BCR, and controllable silicon BCR and lamp connect the civil power two ends.

Since in the desk lamp remote control is housed, therefore can the remote control switch desk lamp.In addition, adopt the pressure regulation integrated package, therefore had dimming function.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is remote control circuit theory diagrams of the present utility model.

Embodiment: as shown in Figure 1, small one and large one two lamps 2,3 are housed on lamp socket 1, in the lamp socket 1 remote control are housed, remote control has the plug P that draws, its circuit theory diagrams as shown in Figure 2, A, B two termination civil powers are through capacitor C 1 step-down, D ₁, D ₂Rectification, D ₃Voltage stabilizing, C ₂After the filtering, for circuit provides stable direct-current working volts, acoustic frequency sensor JS meets triode BG ₁Base stage, audio frequency pass that device JS receives sound signal and the signal of telecommunication that converts to by BG ₁Amplify BG ₁Emitter connect by inductance L, capacitor C ₇The frequency-selective network of forming carries out frequency-selecting by it to signal, output termination triode BG ₂Base stage, by BG ₂Signal after the frequency-selecting is amplified once more, and collector electrode is exported via capacitor C ₆, resistance R ₄The differential circuit of forming connects the triggering pin 1 of pressure regulation integrated package HT7713, and output pin 3 connects the trigger electrode of bidirectional triode thyristor BCR, the angle of flow of the output control BCR of HT7713, the brightness of control lamp N.Receive the sound signal of certain frequency as acoustic frequency sensor JS after, the angle of flow minimum of the output control bidirectional triode thyristor BCR of HT7713, the brightness of lamp is the most weak, after for the second time receiving the sound signal of same frequency, the angle of flow of the output control bidirectional triode thyristor BCR of HT7713 increases, the brightness of lamp improves, after receiving the sound signal of same frequency for the third time, the angle of flow maximum lamp of controllable silicon BCR is the brightest, after receiving the sound signal of same frequency the 4th time, the output voltage of HT7713 is zero, and controllable silicon turn-offs, and lamp extinguishes thereupon.Present embodiment also is provided with one and touches end M, through capacitor C ₃, R ₃The differential circuit of forming is connected to the triggering pin 1 of pressure regulation integrated package HT7713, touches the also brightness of scalable lamp of M.
