1, microwave radar sensor lamp principle
When outside someone or other moving objects, according to the doppler effect (wave when waves move near to the observer to accept high-frequency change, and when the waves away from the observer to accept lower frequency) signal response to launch device, trigger a change of lamps and lanterns, so as long as there is obviously a moving object through the radar sensor will trigger induction, solar street lamps to light, From light or no light to full light and highlight; When the human walking light is dimmed or goes out automatically outside the sensing range.
Microwave radar induction solar street lamp than ordinary infrared induction solar street lamp induction distance, wide Angle, no dead zone, can penetrate glass, and thin wood, according to different power, can penetrate the different thickness of the wall, not affected by the environment, temperature, dust and so on. Radar sensing solar street light has three functions: radar sensing overtime control and light control. The street light will be on when someone or a car passes by in the early night, and it will be on when no one or car passes by. The light will be on automatically at night when the light is not on during the day.
2, microwave radar sensor lamp setting
The built-in setting of radar sensing solar street lamp is to install a radar sensor in the solar street lamp cap to detect the position and relative speed of the moving target. Then adjust the inductor induction distance, induction range, induction Angle, inductor sensitivity, and delay time.
1. Set the detection range
This range is the installation height of the lamp pole and the radius of the approximately circular detection area where the light projection appears on the ground. The detection distance is the minimum when the lamp is rotated counterclockwise to the bottom, and the detection distance is the maximum when the lamp is rotated clockwise to the bottom (it can be set within 5-20 meters). The detection range is set according to the normal value of the human body test with a height of 1.6 to 1.7 meters, medium build, and walking speed of 1.0 to 1.5 meters per second. If the human body height, shape, and walking speed change, the sensing distance will change accordingly.
2. Set the time
It can be set in the range of 10 seconds (counterclockwise to the end) to 30 minutes (clockwise to the end), and the timer will be reset when the movement signal is detected before the end of this time. It is recommended to choose the shortest time when adjusting the detection range or walking test. After the light goes out, it takes nearly a second for it to feel again. Only when the signal is detected after the end of this time, the LED lamp bead will be lit, and you can also set the lighting period freely.
3. Light control setting
Working illumination value can be adjusted in the range of 2-2000lux. The working illuminance value is about 2LUX when rotating counterclockwise to the bottom, and about 2000LUX when rotating clockwise to the bottom. This knob must be turned clockwise to the bottom when walking during the day to test or adjust the detection area.
Radar sensing solar street lamp is suitable for residential roads, courtyard lighting, rural path, park scenic area, factory lighting, and so on. Especially suitable for rural areas. Because the night in the countryside is not as busy as in the city, most of the time there are no people and no cars. If the conventional street light without induction is used, it is a waste of resources in many cases. On the contrary, the installation of radar sensing solar street lamps can not only solve the problem of resource waste but also greatly extend the service life of lamps.
