Core Functions and Technical Features 1. Solar Power Supply System Solar Panel: Utilizes monocrystalline or polycrystalline photovoltaic panels with conversion efficiency ranging from 15% to 22%, enabling rapid charging under sufficient sunlight. For instance, Tenkoolight’s BD series solar panels support 24/7 charging to meet nighttime lighting needs. Battery: Common types include lead-acid batteries or lithium-ion batteries (e.g., lithium iron phosphate), with capacities ranging from 12V/80AH to 24V/100AH, ensuring energy storage for consecutive rainy days. Controller: Equipped with photocontrol + time control functions to automatically adjust brightness. Some products support a "4+8 mode" (4 hours of full brightness + 8 hours of motion-sensing operation), reducing energy consumption by dimming lights during inactive periods. 2. Motion Sensor Technology Detection Range: Typically employs PIR (Passive Infrared) sensors with a detection distance of 8–15 meters and an angular coverage of 120°–180°, enabling precise identification of moving objects. Intelligent Trigger Logic: Automatically adjusts to 100% brightness when human motion is detected; reduces to 20%–30% low brightness or turns off completely when no activity is detected, extending battery life. Multi-Mode Switching: High-end models support customizable operation modes, such as adjusting full-brightness duration and motion sensitivity.
