LED is considered to be the green lighting source in the 21st century. LED is a solid-state semiconductor device, which can directly convert electricity into light, with high light efficiency and low energy consumption.
Low-power radar microwave induction technology is one of the most advanced intelligent LED light product technologies at present, which can effectively reduce lighting power consumption, reduce energy waste, and achieve the purpose of energy saving and emission reduction.
The radar sensor module itself has an antenna for transmitting and receiving microwave signals. Its basic working principle is that the microwave signal generated by the module is transmitted to the space by its own loop antenna, and then a three-dimensional space microwave protection area is generated. Along the axis is an elliptical and adjustable space microwave detection field. According to the Doppler effect of electromagnetic waves, the human body will reflect the microwaves emitted by the antenna. When people or other objects move in the area, the antenna will receive the reflected microwave signal, and after detection, amplification, shaping, multiple comparisons, and delay processing by the internal circuit of the module, it will automatically control the lamp to turn on or off. operation, so as to achieve energy saving effect.
The inductive LED lighting based on the microwave radar detection module can be controlled by itself and has a delay effect through signal detection, amplification, shaping, and multiple comparisons. The lighting has the advantages of not being affected by its own light in the working state of the circuit, and is easy to install.
