Lamps have a very important role in our entire home life, and now there are many types of lamps on the market. As a new type of lamps, voice-activated lamps bring more colors to people's lives, but many people The method of installing the voice control lamp is not very clear. Here, Xiaobian will give you a detailed introduction on how to install the sound control lamp properly? What is the principle of the voice control lamp?
What is the principle of the voice control lamp?
1. The voltage is changed. Generally, the voltage of China's voice-activated lamps is standard 220v AC. Therefore, China's voice-activated lamps are based on 220v AC, which is converted into DC ripple voltage by the bulb.
2, the formation of current, in the daytime, when the light is relatively strong, the photodiode D of the voice-activated lamp exhibits a bottom resistance state, the resistance is less than or equal to 1 kohm, at this time the triode v of the voice-activated lamp is cut off, its The emitter has no current output.
3, illuminate, and at night, when the light is dark, the photodiode D of the voice-activated lamp exhibits a high resistance, and its resistance can reach 100 kohms or even higher. At this time, if there is a sound source, the sound control will be achieved. The triode V of the lamp is forwarded to make the bulb of the voice control lamp emit light.
4. According to the working principle of the voice-activated lamp, the voice-activated lamp should be controlled by sound and light at the same time. Therefore, the voice-activated lamp is also called the sound-light control lamp, or it can be understood as the abbreviation of the sound-control lamp. According to the principle of the voice-activated lamp, we understand why in the day when the light is sufficient, no matter how we make a sound or how much sound is emitted, it does not light up.
How to install the sound control lamp?
1. When the installation is not required to light up, the voice-activated switch needs to have enough light illumination, so even if the noise is too large, it will not affect its normal use.
2. It is a switch, not an electrical appliance, so it is not necessary to access both the neutral and the live. For security reasons, I recommend that you access the FireWire. That is to cut in one of the places, in turn access to the input and output.
3. If the environment you are in is not turned on, the lighting is not good, then you should pay attention to the switch installation. If you don't want to always be bright, then you can choose to install it next to the window. That way, the photosensitive element of the voice-activated switch can be known, that is daylight, no need to be bright. Needless to say at night, the opposite is true.
4. LED sound control lamp LED sound control lamp is equipped with a kind of voice-activated electronic lighting device. The LED sound control lamp is composed of microphone, audio amplifier, frequency selection circuit, voltage doubler rectifier circuit, amplitude-amplifying circuit, constant voltage source circuit and delay. The circuit, the controllable delay switch circuit and the thyristor circuit are composed.
5. According to the type of lamps, the LED sound control lamps commonly used in the market are: LED sound control hot wheels, LED sound control bulbs, LED sound control sunflowers, etc.; according to the working principle: simple voice control LED lights are added switching power supply to achieve its function , only the lamp switch can be realized;
6. The other type can be composed of a microphone, an audio amplifier, a frequency selection circuit, a voltage doubler rectifier circuit, a voltage amplitude circuit, a constant voltage source circuit, a delay open circuit, a controllable delay switch circuit, and a thyristor circuit. Its function can realize that when the sound is activated, the luminaire is fully bright. When the sound is silent or the sound does not meet the activation requirements of the luminaire, the low-power operation can be maintained, such as the 15W voice-activated LED fluorescent lamp, which is only 4-5W when not activated;
7. LED sound control lamp (When the external sound is higher than -38±3DB, the LED fluorescent lamp automatically enters the full power output mode, and the delay is 15±2S (the time can be adjusted according to the actual demand). At this time, if the sound is lower than -38± When 3DB, the LED fluorescent lamp enters the low output power mode and keeps the brightness 4W. If the sound is still higher than -38±3DB, the LED light enters the full power output mode again and reaches 15W. Then delays 30S.)
