Down lamp with monitoring function

The invention relates to the technical field of lighting fittings, in particular to a down lamp with a monitoring function. The down lamp comprises a radiator, a power control module, a casing, an LED light source plate and a lens, wherein a heat conducting substrate is arranged on the front end surface of the radiator; the LED light source plate is tightly connected to the front end surface of the heat conduction substrate; a mounting hole is formed in the center of the radiator; a spherical camera module is mounted at the front end of the mounting hole of the radiator; a master control box is fixed at the rear end of the radiator; a main control panel, a WIFI (wireless fidelity) module and a DSP (digital signal processing) module are arranged in the master control box. According to the down lamp with the monitoring function, lighting and monitoring functions are integrated, are mutually independent and are not influenced, functions are diversified, resources are effectively saved, usage and operation are simple, convenient and flexible, the applicable range is wide, and furthermore, the down lamp has a larger monitoring angle range, saves more space and is small in size.
