Abstract
A lighting apparatus includes a main module and an extended module. The main module includes a power circuit, a light source, a first network interface and a controller. The power circuit is controlled by the controller to generate a driving current supplied to the light source by converting an external power source. The extended module includes a function circuit and a second network interface. 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. When the extended module is detachable from the main module, the main module is operated independently without the extended function.
