Description

Magnetic induction module, lighting module and lighting fixture

This manual control method is not good in real time and convenience. The current radar sensing LED lamp improves the inconvenience of manual control, and is therefore increasingly popular with users. This radar sensing lamp automatically controls the light source to light up through the sensing module. When a person or a warm object enters the sensing range of the module, the sensing module will output a high-level pulse signal or a high-level delay signal. The output sensing pulse or delay signal can directly drive the indicator light and the lighting lamp. However, the existing radar sensors are all installed by screw tightening. If damaged, not only do they need to be disassembled with the help of tools, but the disassembly process is also cumbersome, labor-intensive and time-consuming. In addition, the existing sensors are not well matched with the lamps, occupy a large space and are not beautiful due to their abruptness, which does not meet the current user's pursuit of beautiful, practical and economical lamps.
