A multiple detection function modularized lighting device includes a housing having a front end in which positioning holes are formed and a detection module including sensors, a control module including a camera lens, an LED module, and a main power supply board mounted inside the housing. The control module is arranged to extend through a central portion of the detection module with the camera lens and the sensors embedded in the positioning holes. The main power supply board is electrically connected to the modules to allow the control module to drive the modules to each perform a corresponding operation, so as to provide the device with functions of detection, image recording, and lighting in multiple ranges.
