About human induction switch

In ancient times, human beings used the natural light source, the sun gave human beings and all living things the chance to survive, but for the night, human beings could do nothing, then intelligent human beings discovered the fire, lighting with fire should be a milestone in the history of human lighting.

Candles have played an important role in Chinese and foreign history, accompanying mankind for thousands of years, until 1879 when the brilliant inventor Thomas Edison made a brilliant entry in the history of lighting.

Electric light has undoubtedly become an indispensable commodity in modern life.

Traditional lighting system has simple structure, low cost and easy installation and use, has been the leading role of the lighting market, with the progress of technology, the improvement of people's living standards, the lamp exposed many deficiencies: first, because it is a manual switch, people have to grope for the light switch in the dark, caused a lot of inconvenience to people's life.

Second, waste of electric energy is serious, be in especially the place of collective life such as school, factory, floodlight often also works in the daytime with sufficient light, this not only waste electric energy, and also cause bulb to often be burned out, if cannot be repaired in time, can produce other inconvenience again.

Thirdly, the rapid development of electronic technology, automatic control technology and sensor technology makes people more and more inclined to the automatic control of lighting equipment.

With the development of modern electronic technology and the change of people's demand for the quality of life, traditional switches have been threatened by product upgrading.

Aim at a problem, the illume switch on the market also is in endlessly, main sound light control switch, touch type delay switch, infrared induction type switch, microwave induction switch, the sound control switch in corridor is a kind of remote control device.

Since the induction components of sound control are mechanical, they are susceptible to mechanical fatigue, and it is difficult to overcome the high sensitivity at the first installation and low sensitivity at the later installation.

Therefore, in the late stage of use, the sound-light switch can only be triggered by artificial noise. For example, if you want the light to come on, you need to cough loudly or stamp your feet, which obviously disturbs the silence of others, especially those who often sleep at night.

In addition, sound-light control is easy to respond to all the larger sounds in nature (such as thunder, car horn, engine sound when the car passes by, electric drill sound when decorating the room, sound of switch and security door, etc.), and there are many false actions.

And touch in addition to vulnerable, unsafe, and infectious diseases, it is difficult to be used in public relations venues, especially in hospitals such complex personnel places.

But the infrared induction switch can overcome the above two kinds of switch defects, so in the actual use of brilliant.

Microwave induction switch has been well received by consumers due to the infrared induction switch of human body [1].
