Question 1

What does an occupancy sensor do?

Accepted Answer

Occupancy sensors detect motion or the presence of objects within their given range. Sensors detect movement or objects and transmit the signal to the control unit(LED driver). If no motion or heat signal (infrared) is detected after a period of time set by the user, the controller judges that the space is empty and will turn off the light or dim the light.

Question 2

What are the 3 types sensors be used on LED lights?

Accepted Answer

There are various sensing technologies can be used in LED light, and the most common are PIR sensor, microwave sensor, and daylight sensor. For example high bay light with motion sensor, it can turn lights on and off, or adjust the output power of lights. While street light with daylight sensor(Photocell), it will turn on lamps when it’s dawn and turn off lamps when it’s morning.

Question 3

What kind of cable or flex is suitable for DALI?

Accepted Answer

The most commonly used cables for DALI are multicore cables, which also carry mains power. A typical cable might be 5 conductors (Live, Ground, Neutral, DA, DA) or 6 conductors (Live, Emergency Live, Ground, Neutral, DA, DA).
