Methods and apparatus for providing modular functionality in a lighting assembly
A lighting assembly includes a base assembly configured to fit into a conventional light bulb socket. A separate bulb assembly is configured to interface with the base assembly, making the bulb and base assemblies selectively separable from one another. In some instances, a module configured to be connected to the base assembly provides a convenient means for adding or supplementing functionality to the lighting assembly. At least in some cases, the module is configured to take the place of the bulb assembly on the base assembly, and is configured to provide a separate interface to which the bulb assembly is coupled, such that the module is disposed intermediate the base assembly and the bulb assembly. In some instances, functionality associated with a lighting element of the lighting assembly is included in the base assembly or the bulb assembly.
