In ancient times, human beings used natural light sources, and the sun gave humans and all creatures the opportunity to survive. However, they could not do anything for humans at night. Then the wise humans discovered the fire. Lighting with fire should be a milestone in the history of human lighting. In the history of China and abroad, candles have played an important role in escorting people to spend thousands of years slowly until 1879 when Edison, the inventor of genius, added a wonderful touch to the history of lighting. Electric lights have undoubtedly become an indispensable commodity in modern life.
The traditional lighting system is simple in structure, low in price and easy to install and use. It has always been the protagonist of the lighting fixture market. With the advancement of technology and the improvement of people’s living standards, this kind of lamp has exposed many shortcomings: First, it is a manual switch. People have to grope for light switches in a dark and inconvenience to people's lives. Second, there is a serious waste of electrical energy, especially in schools, factories and other places where people live collectively. Lights often work in sunny days. This not only wastes electricity, but also causes the bulb to be burned out. If it cannot be repaired in time, it will Other inconveniences arise. Third, the rapid development of electronic technology, automatic control technology and sensor technology has led people to be more inclined to the automatic control of lighting equipment. The development of modern electronic technology and changes in people's demand for quality of life have made traditional switches feel the threat of product upgrading. In response to the problem, the lighting switches on the market are also emerging, mainly sound and light control switches, touch-type delay switches, infrared inductive switches, microwave sensor switches, etc. The voice-activated switch in the hallway is a remote control device. Since the voice-activated components themselves are mechanical, they are susceptible to mechanical fatigue and it is difficult to overcome the sensitivity of the initial installation and the low sensitivity of the later stage. Therefore, in the later period of use, the sound and light control switch can only be triggered by artificial noise. If you want the light to need a loud cough, or you're lame, this obviously disturbs the quietness of others, especially those who affect sleep at night. In addition, the sound and light control is easy to respond to all the larger sounds in nature (such as thunder, car horns, engine sound when the car passes through, the drill sound of the decoration room, the sound of the switch security door, etc.), and more malfunctions. In addition to being vulnerable to damage and insecurity, touch-sensitive devices are also contaminated with infectious diseases, and are difficult to apply in public relations venues, especially in complex sites such as hospitals. Infrared inductive switches can overcome the defects of the above two types of switches and thus shine in practical use. At present, microwave sensor switches have received favorable comments from consumers because of human body infrared sensor switches.
