According to the utility model discloses an embodiment, ultraviolet germicidal panel lamp still includes inductor 90, and the response port of inductor 90 sets up in the below of grid 2. Inductor 90 is used for detecting ultraviolet sterilization panel lamp and shines whether someone exists in ultraviolet region, for example when carrying out operations such as roof maintenance, can someone be at indoor aerial work, continue to shine the ultraviolet ray to 1 outside of lamp body this moment, can cause harm to operating personnel, and inductor 90's existence can detect the personnel of aerial work in real time, thereby make ultraviolet sterilization module stop work, the control device or the circuit of control ultraviolet sterilization module stop work can choose the conventional control device or the circuit in this field for use, the utility model discloses the description just no longer has repeated.

In a specific example, the sensors 90 are disposed at the sides of the lighting module 90, and preferably, the sensors 90 are disposed at each side of the lighting module 90, so as to ensure the accuracy of the detection result.
