The LED unit adopts the LED filament, can improve luminance, reduce the energy consumption.

Referring to fig. 2, in the embodiment, the rechargeable battery and boost module includes a battery management chip SP4533, a charging indicator D1, a discharging indicator D2, and a rechargeable battery BAT, where the charging and discharging indicator is used to display a charging and discharging state of the rechargeable battery, and the rechargeable battery is used to store electric energy and supply power to the circuit. The charge indicator lamp D1 is connected in the LED1 pin of battery management chip SP4533, the discharge indicator lamp D2 is connected the LED2 pin of battery management chip SP4533, rechargeable battery BAT is connected the BAT pin of battery management chip SP4533, and the OUT pin of battery management chip SP4533 is the output that steps up, for the circuit provides 5V's voltage, connects the VDD of battery management chip SP4533 is the input pin that charges for being connected with external power supply charges for rechargeable battery.

The anode of the microphone MIC is connected with the OUT pin of the boost output of the battery management chip SP4533 through a resistor R2, and is also connected with a capacitor C5, the cathode of the microphone MIC is grounded, a capacitor C5 is connected with the base of a triode Q1 and a resistor R4, a resistor R4 is connected with the base and collector of a triode Q1, the emitter of the triode Q1 is grounded, a resistor R3 is connected with the OUT pin of the SP4533 of the battery management chip, the collector of a triode Q1 and a resistor R5, a resistor R5, a capacitor C6 and a resistor R6 are connected in series in sequence, a resistor R6 is connected with the anode of a photoresistor RS and a resistor R7, the cathode of the photoresistor RS is grounded, a resistor R7 is connected with the base of a triode Q2, and is connected with the ground after being connected with the resistor R8, the emitter of a triode Q9 is grounded, the collector of a triode Q2 is connected with the OUT pin of the battery management chip SP4533 through a resistor R9 and is connected with the base of a triode Q3, the emitter of the triode Q3 is connected with the anode of the diode D4, the cathode of the diode D4 is respectively connected with the ground through the capacitor C7 and the base of the triode Q4 through the resistor R10, the collector of the triode Q4 is respectively connected with the anode of the diode D5 and the coil of the relay K, the cathode of the diode D5 is connected with the OUT pin of the battery management chip SP4533, one end of the switch of the relay K is connected with the OUT pin of the battery management chip SP4533, and the other end of the switch is connected with the LED unit through the resistor R11.

When there is no sound: the microphone MIC does not have the sound signal, triode Q1 is in the amplification state that stands still, and electric capacity C6 separates the effect of direct traffic, lets triode Q2's base have no bias voltage and be in the off-state, therefore triode Q3 is also in the off-state for there is not voltage on the electric capacity C7, and triode Q4 is also in the off-state, and the relay does not work, and the LED lamp is not bright. Therefore, in the absence of sound, the LED is not lit regardless of whether there is sufficient light intensity.

With sufficient light intensity: daytime, the highlight shines, and when the luminous intensity was higher than the threshold value, photo resistance RS was low resistance, and electric capacity C3 short circuit, triode Q2 cut off, and consequently triode Q3 also is in the cut-off state for there is not voltage on the electric capacity C7, and triode Q4 also is in the cut-off state, and the relay is out of work, and the LED lamp is not bright. Thus, with sufficient light intensity, the LED will not light, whether with or without sound.

When the weak light irradiates with sound: when weak light irradiates and the light intensity is lower than the threshold value, the photoresistor RS is in a high impedance state, and compared with the resistance values of the resistor R7 and the resistor R8, the photoresistor RS is in an open circuit state. An audio signal output by a microphone MIC is amplified by a triode Q1 to generate an audio signal with extremely high amplitude at a collector, the audio signal is coupled by a capacitor C6, the positive polarity part of the amplified audio signal passes through a resistor R5, a resistor R6, a resistor R7 and a resistor R8 to divide voltage and provide a strong enough base bias for a triode Q2, the triode Q2 enters a conducting state to enable the triode Q3 to enter a saturated conducting state, a power supply charges a capacitor C7 through triodes Q3 and D6, the capacitor C7 can be charged in the period of time due to the fact that the frequency of the audio signal is not very high and the sound signal has certain duration, the capacitor C7 provides enough conducting voltage for the triode Q4 through the resistor R10 at the moment, the excitation current of the triode Q4 enables a relay to work, a normally open contact is closed, a normally closed contact is opened, and an LED unit obtains enough current and is in a light-emitting state. When the sound signal disappears, because the D4 is reversely biased, the charge on the capacitor C7 can only pass through the resistor R10, the transistor Q4 discharges, and the discharge time constant of the capacitor C7 and the resistor R10 is relatively large, the transistor Q4 keeps continuously conducting, and the normally open contact of the relay keeps continuously closed until the voltage on the capacitor C7 is not enough to conduct the transistor Q4, and the LED unit returns to the off state.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
