In order to achieve the aforementioned objects, according to an embodiment of the present disclosure, a sensing module is provided. A sensing module, detachably connectable to a light body, the sensing module comprising: a sensing unit, having at least one sensor, a control circuit and at least one operating parameter adjusting element, the sensor and the operating parameter adjusting element electrically coupled to the control circuit, the control circuit disposed in the sensing unit; and a connecting module electrically coupled and mechanically connected with the sensing unit; wherein the connecting module is detachably connectable to the light body.

In one embodiment, the connecting module is constructed to comprise a screw-in base disposed on the top of the sensing module and a screw-in socket disposed under the sensing module, wherein the screw-in base allows the sensing module electrically connectable with the light body; wherein the screw-in socket allows a screw-in light source connectable to the sensing module. The screw-in base and socket are just taken for example. It could be another type of sockets such as bi-pin or GU24.
