Embodiment
The utility model LED lamp sound-controlled apparatus, opens by Sound control LED lamp, and controls the opening time of LED lamp, to avoid LED lamp to cause waste.Directly driving LED lamp matrix of described LED lamp sound-controlled apparatus, is convenient to install, and solves the switch control problem of current public place LED lamp, saves the energy.
With reference to the accompanying drawings the embodiment of LED lamp sound-controlled apparatus described in the utility model is described in detail.
As shown in Figure 1, LED lamp sound-controlled apparatus 10 gathers acoustic information, controls its internal switch closure, and output ripple direct current carries out after constant current driving through constant-current source module 20, controls LED lamp matrix 30 and opens.Described LED lamp sound-controlled apparatus 10 comprises main control unit 101, and the rectification unit 105, sound collection unit 103, time delay control unit 104 and the switch 105 that are connected respectively with main control unit 101.It should be noted that, in Fig. 1, dotted line is for supplying electrical schematic, and solid line is control information schematic diagram.
Rectification unit 105 is for being converted to Rectified alternating current by outside 220V alternating current.As shown in Figure 2, the function of rectification unit 105 realizes by rectifier bridge.This pulsating dc voltage one end exports the anode of thyristor Q2 to, and the other end, through the first resistance R 7 step-downs, is the DC power supply of LED lamp sound-controlled apparatus 10 internal components after the second capacitor C 3 filtering.
Sound collection unit 103 is for gathering acoustic information.As shown in Figure 2, sound collection unit 103 is by sound transducer BELL and the first capacitor C 1 being connected in series and triode Q3 composition.The acoustic information that sound transducer BELL gathers is coupled through the first capacitor C 1, and triode Q3 amplifies rear output.
The acoustic information of main control unit 101 for gathering according to sound collection unit 103, controls the conducting of described switch.As shown in Figure 2,3, main control unit 101 is by being realized by first to fourth 4 chips that the model that independently NAND gate (U1A, U1B, U1C, U1D) forms is CD4011.
Described switch is realized by thyristor Q2, and thyristor Q2 is connected with the pin one 1 of chip CD4011 by the 3rd resistance R 6.In addition, described switch also can be realized by triode, repeats no more.
Preferably, also comprise a photo resistance R8, be connected with main control unit 101.
In the time having illumination by day, the resistance less (10K～30K) of photo resistance R8, its both end voltage is low, the pin two of CD4011 is low level, pin 3 becomes high level, and after U1B, U1C, tri-NAND gate of U1D, pin one 1 pin is low level, the control utmost point G that is thyristor Q2 is low level, thyristor Q2 cut-off.
After night is unglazed photograph, photo resistance R8 resistance is very high, its both end voltage higher (90M Ω～100M Ω), and the pin two of CD4011 becomes high level, and the state of pin 3 is subject to pin one control, if pin one is high level, pin 3 is low level; If pin one is low level, pin 3 is high level.Thus, in the time that pin one receives voice signal, become high level, pin 3 becomes low level, and after U1B, U1C, tri-NAND gate of U1D, pin one 1 is high level, and thyristor Q2 controls the utmost point and becomes high level, thyristor Q2 conducting.
