Utility model content
The purpose of this utility model is to provide the lamp of readily taking the opportunity to that a kind of size according to sound controls LED light and shade.
The LED that the utility model provides comprises input power, also comprise the first resistance, second resistance, 3rd resistance, first electric capacity, capacitor microphone, first triode, second triode and diode, one end ground connection of described capacitor microphone, the other end is connected with one end of the first resistance, the other end of the first resistance is connected with power supply, the node that first resistance is connected with capacitor microphone is connected with one end of the first electric capacity, the other end of described first electric capacity is connected with the base stage of the first triode, the base stage of described first triode is connected with one end of the second resistance, the other end of described second resistance is connected with power supply, first triode penetrate a grade ground connection, the collector electrode of the first triode is connected with one end of the 3rd resistance, the other end of the 3rd resistance is connected with power supply, the base stage of described second triode is connected with the collector electrode of the first triode, second triode penetrate a grade ground connection, the collector electrode of the second triode is connected with the negative pole of diode, the positive pole of diode is connected with power supply.
Further, be stable input voltage, also comprise the second electric capacity, the positive pole of described second electric capacity is connected with power supply, minus earth.
Beneficial aspects of the present utility model is: detect surrounding environment by using capacitor microphone, can realize light-emitting diode along with the power of environmental sound signal flashing, the utility model is applied in public transport stop board, except electrical energy saving can be realized, too increase the enjoyment of passenger, and realization with low cost is simple.
Accompanying drawing explanation
Fig. 1 is LED theory diagram of the present utility model.
Wherein 1 is capacitor microphone, and 2 is the first electric capacity, and 3 is the first resistance, and 4 is the second resistance, and 5 is the 3rd resistance, and 6 is light-emitting diode, and 7 is the second electric capacity.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
The utility model improves a kind of LED control circuit of power control light-emitting diode light and shade of environmentally voice signal, comprise input power, also comprise the first resistance 3, second resistance 4, 3rd resistance 5, first electric capacity 2, capacitor microphone 1, first triode 8, second triode 9 and light-emitting diode 6, one end ground connection of described capacitor microphone 1, the other end is connected with one end of the first resistance 3, the other end of the first resistance 3 is connected with power supply, the node that first resistance 3 is connected with capacitor microphone 1 is connected with one end of the first electric capacity 2, the other end of described first electric capacity 2 is connected with the base stage of the first triode 8, the base stage of described first triode 8 is connected with one end of the second resistance 4, the other end of described second resistance 4 is connected with power supply, first triode 8 penetrate a grade ground connection, the collector electrode of the first triode 8 is connected with one end of the 3rd resistance 5, the other end of the 3rd resistance 5 is connected with power supply, the base stage of described second triode 9 is connected with the collector electrode of the first triode 8, second triode 9 penetrate a grade ground connection, the collector electrode of the second triode 9 is connected with the negative pole of light-emitting diode 6, the positive pole of light-emitting diode 6 is connected with power supply.
Time static, first triode 8 is in critical statisfaction state, second triode 9 is ended, light-emitting diode 6 is not luminous, one resistance 3 provides bias current to capacitor microphone 1, namely capacitor microphone 1 transfers the corresponding signal of telecommunication to after picking the acoustic signals in indoor environment, deliver to the first triode 8 through the first electric capacity 2 and carry out method, first triode 8 and the second triode 9 form two-stage direct-coupling amplifying circuit, after capacitor microphone 1 picks acoustic signals, audio signal is just had to inject the base stage of the first triode 8, the negative half period of its signal makes the first triode 8 exit saturation condition, the collector voltage of the first triode 8 rises, second triode 9 conducting, light-emitting diode 6 is luminous, when input audio signal is more weak, be not enough to make the first triode 8 exit saturation condition, light-emitting diode 6 keeps extinguishing.When only having stronger signal to input, diode 6 is just luminous.
