The working principle of the radar sensing bracket lamp

1. Radar Sensing Mechanism: The lamp uses 24GHz microwave radar technology to emit electromagnetic waves. These waves reflect off moving objects (e.g., humans, pets) within the detection range. The sensor detects frequency changes in reflected waves (Doppler effect) to identify motion.

2. Signal Processing: A built-in control module processes the reflected signals. It distinguishes valid motion from interference (e.g., wind, insects) via algorithmic filtering, ensuring accurate activation only for significant movements.

3. Light Activation: Upon detecting motion, the module triggers the lamp to turn on at full brightness. This response is typically instant (within 0.1-0.3 seconds) due to the high-speed nature of radar signals.

4. Duration Control: After motion stops, the lamp remains on for a preset time (adjustable, e.g., 10-600 seconds) set via internal timers. This prevents frequent on/off cycles and saves energy.

5. Dimming & Standby Modes: Some models feature a low-brightness standby mode (e.g., 10% brightness) when no motion is detected. Motion reactivates full brightness, balancing energy efficiency and convenience.

6. Environmental Adaptability: Radar penetrates non-metallic materials (glass, plastic) and works in darkness or low light, unlike PIR sensors. It resists temperature/humidity changes, ensuring reliability in diverse indoor/outdoor settings.
