Sound -controlling lights are a sound -controlled electronic lighting device, which consists of audio amplifiers, frequency selection circuits, delayed turning circuit and silicon circuit.The sound control light should be full name-sound light control lights.Because it is also related to light.During the day, you will not set off firecrackers.There is an interesting phenomenon of sound control lights, that is, when the light is sufficient, the sound of any of you does not make a sound; but in the night, it emits lightly.

Sound control lights are always on
First, the reason for Changliang 1. There is a problem with the thread of the light bulb (short -circuit).2. The power of the bulb is too small, the silver control cannot be turned off.3. Environmental noise.4. Mi head frequency is too width.5. There is also a large DC component.Two, two methods 1. Replace the sound control lamp head.2. Change the energy -saving lamp or change a bigger light (such as 100W).
How to install the sound control lamp
First of all, when you install it, when you dont need light, the voice control switch needs enough lighting.That way, even noise will not make it trigger.Secondly, it is a switch, not an electrical appliance, so it does not need to connect to the neutral line and the line.For security considerations, it is recommended that you connect to the fire.That is, cut in one of the places, and connect to the input and output end in turn.Third: If the light is not turned on and the lighting is not good, then pay attention when the switch is installed. If you dont want to be bright, you can choose to install it next to the window.That can let the sensor of the sound control switch know that it is daytime and does not need to be bright.Needless to say at night, vice versa.
Principles of sound control lamps
1. The original sound control lights have light control circuits in the sound control light, so that they do not work when the light is sufficient, so the control box of the sound control light is actually sound and light control.It will be on.You can do a small experiment. You can use your hand to block the original light control of the sound control switch and then make a sound, and the light will be turned on.Second, the working principle of sound control lights 1. Transition voltage. Generally, the voltage of Chinas acoustic control lights is a standard 220V AC electricity. Therefore, my countrys acoustic control lights are standard based on 220V AC power, and it transforms it into a DC pulse voltage through light bulbs.2. Form current. When the light is strong during the day, the light -sensitive diode D of the sound control lights shows a foundation state, and the resistance should be less than or equal to 1,000 Euros. At this timeThere is no current output.3. Elapnge, and at night, when the light is darker, the light -sensitive diode D of the sound control lights shows a high resistance. The resistance can reach 100,000 Euros or even higher.The triode V of the lamp is turned on, so that the light bulb of the sound control lights shines.
