How does the sound control of stage lights work?
The sound control of stage lights is mainly achieved through sound control light technology, and its working principle is as follows:
The switch control circuit of the voice controlled light is equipped with a microphone, a photosensitive tube, and a delay circuit, among which the photosensitive tube is mainly composed of controllable silicon.
When the ambient light is strong enough, the photosensitive circuit composed of thyristors controls the switch to be in the off (off) state. When the ambient light intensity is not enough, the control of the photosensitive tube is no longer effective, and the microphone begins to work. When there is strong enough sound from the outside world (such as clapping), the microphone picks up the sound signal, making the switch conductive (on), and the lamp will be lit up. After the light is on, the circuit will be delayed and closed. After a certain period of time, the circuit will be closed. At this time, the light will go out, thus achieving the function of controlling the lighting fixtures with sound.
In addition, the lights of the sound control switch use sound sensing devices such as microphones to capture sound signals and convert them into electrical signals. Then, the sound signal is amplified through an amplification circuit, and other irrelevant noise is filtered out through filtering processing.
Next, the amplified and filtered sound signal is analyzed and identified through detection and comparison circuits. The control switch can set a threshold, and when the intensity of the sound signal exceeds or equals this threshold, the switch action will be triggered. When the intensity of the sound signal reaches or exceeds the threshold, the control circuit will trigger a switch action, sending the circuit control signal to the control interface of the lamp, and achieving the switch operation of the lamp by controlling the on/off of the switch.
Overall, the sound control of stage lights is achieved through steps such as capturing sound signals, converting them into electrical signals, amplifying and filtering, detecting and comparing, and triggering switch actions.
At the same time, the control of the photosensitive tube and the operation of the delay circuit are also combined to ensure that sound can effectively control the switch status of the lamp under appropriate ambient light conditions.
