Please refer to FIG. 11 showing a schematic diagram of a sensing lamp according to another embodiment of the present disclosure. The sensing module 522 is not disposed on the light body 51, but on the back plate 52. In other words, the major difference between the sensing lamp 5 and the previous embodiments is the sensing module 522 is disposed on the back plate 52. The sensing unit (not shown in FIG. 11, referring to the sensing unit 221 shown in FIG. 4) of the sensing module 522 rotatably connects to the back plate 52. Additionally, the sensing lamp 5 shown in FIG. 11 comprises two light bodies 51, but the appearance of the sensing lamp 5 is not for restricting the scope of the present disclosure. The sensing module 522 can comprise an infrared sensing unit, a microwave sensing unit, a light sensing unit, or any combination thereof, but the present disclosure is not so restricted. The design concept of the sensing module 522 is identical to that of the sensing module 22, that is to say the design concept of the operating parameter adjusting element of the sensing module 522 is identical to the operating parameter adjusting element 2213 of the previous embodiment, thus the redundant information is not repeated.
