With the rapid development of science and technology, our lives are becoming more convenient and interesting. One of them is the popularity of voice-controlled lights. The birth of this technology makes traditional manually controlled lamps intelligent, and their switches can be easily controlled by voice. During the day, even if the surrounding sounds are noisy, the lamps remain silent; and when night falls, just clap your hands and the lamps will light up and dispel the darkness.

- Function and principle of voice-controlled lights
-- Convenience of voice-controlled lights
Voice-controlled lights use sound to control the switch of lamps without manual operation. This feature greatly improves convenience, especially at night when light is insufficient. It allows people to avoid groping for switches in the dark, and worry about the waste of resources caused by forgetting to turn them off.
--Internal composition and working principle
The magical function of voice-controlled lights is inseparable from their unique composition structure. The microphone, photosensitive tube and delay circuit installed in the lamp work together to complete the task of sound-controlled lighting devices. Among them, the photosensitive tube is mainly composed of thyristors, and its conduction and blocking are precisely controlled by the brightness of the ambient light. At the same time, the microphone is responsible for picking up the sound intensity. When there is sufficient light, the photosensitive tube composed of thyristors will control the switch to remain in the off state; when there is insufficient light, the control effect of the photosensitive tube will weaken, and the microphone will start working. Once there is a strong enough sound in the outside world, such as clapping, the microphone will capture the sound signal, switch the switch to the on state, and the lamp will light up immediately. Subsequently, the delayed shutdown circuit will start, and the switch will be automatically turned off after a period of time, and the lamp will go out, thus realizing the lighting function of the voice-controlled lamp.
- Application and limitations of voice-controlled lamps
--Advantages and daily applications
Voice-controlled lamps are widely used in daily life. It not only saves electricity resources, but also allows people to not have to grope for switches in the dark, and there is no need to worry about the waste of resources caused by forgetting to turn them off. This convenient way of use makes it the preferred lighting device for many homes and public places.
--Limitations and environmental impacts
However, voice-controlled lamps also have certain shortcomings. Due to frequent switching operations, the service life of the bulb may be affected. Voice-controlled lamps have the problem of short service life. In addition, the sound and light of voice-controlled lamps when used at night may also cause certain noise and light pollution to the environment. It is worth noting that, due to the inherent characteristics of energy-saving lamps or LED lamps, most of the voice-controlled lamps currently on the market can only be used to control traditional incandescent lamps. These lamps not only have low energy utilization, but also have a relatively short service life.
--Future development and new technologies
With the advancement of technology, new sensing devices such as infrared sensing lamps have emerged. They can automatically light up when people approach, effectively solving many of the drawbacks of voice-controlled lamps. New lamps significantly extend their service life through automatic sensing lighting and improved energy efficiency, bringing a more efficient and sustainable direction to the development of future home lighting equipment.
