Should Street Lamp using Microwave Radar Induction or Infrared Induction?

2022-05-25

Generally speaking, there are three differences between radar induction LED lamp and human body induction LED lamp, which are the induction principle, induction distance, and the appearance shape.
1.The induction principle; Radar sensing LED lamps are used in, The Doppler radar induction principle, Pdlux company has developed a plane antenna board, Planar 360-degree emission microwave induction signal, Once a moving object enters the sensing distance, The radar signal waveform emitted by the plane antenna changes, The changed radar wave sensing is received by the planar antenna, The Smart IC will issue instructions to change the operating status of the lamp, Human induction is the principle of pyroelectric detection, Simply put, it senses the temperature changes in the environment, Once 37.2 degrees of human sensing or other objects near infrared energy will enter the range will respond; 
2.Induction distance: radar sensing LED lamp, An inductive distance of up to 8-10 meters, If used in a garage, The light will on 1-3 meters before the light, Human body sensing in winter sensing distance is 3-5 meters, The car was not turned on until under the light, summer, The inductive distance is only 1-3 m, The car to the light sometimes does not light; 
3.Appearance shape: radar sensing technology characteristics, Ppenetrate nonmetallic objects, So the radar sensor can be built inside the lamp, It looks like a regular LED lamp, In fact, with the radar sensing function, Characteristics of human body sensing technology, The human body sensing receiver head must be exposed, Phemand Lens, Need to collect the infrared energy changes to the environment, 

To sum up: the street lamp using microwave radar induction is better than infrared induction.
