1. A lighting apparatus, comprising:
a main module comprising a power circuit, a light source, a first network interface and a controller, wherein the power circuit is controlled by the controller to generate a driving current supplied to the light source by converting an external power source; and
an extended module comprising a function circuit and a second network interface, wherein the function circuit communicates with the controller via the second network interface and the first network interface to add an extended function for the controller to enhance controlling of the light source, wherein when the extended module is detachable from the main module, the main module is operated independently without the extended function, wherein the function circuit comprises a light unit, wherein the controller controls the light unit via the first network interface and the second network interface.
