1. A light bulb, comprising:
- a housing comprising at least one surface through which light may pass, the housing further comprising a threaded metal base compatible with a light fixture with an Edison screw socket, wherein the threaded metal base is electrically connected to the light bulb, the housing further comprising an outwardly extending flange that extends circumferentially about an axis along which the threaded metal base is rotatable;
a radio frequency identification (RFID) reader integrated within the housing, the RFID reader comprising at least one antenna that at least partially extends into the outwardly extending flange of the housing, the RFID reader comprising an active reader;
a light source integrated within the housing, the light source configured to emit light through the at least one surface;
a motion sensor integrated within the housing, the motion sensor configured to detect motion within a space in which the light bulb is installed;
at least one processor and a memory integrated within the housing, the at least one processor in communication with at least the motion sensor and the RFID reader;
a power reserve integrated within the housing, the power reserve coupled to the at least one processor, the memory, the RFID reader and the motion sensor, the power reserve being configured to power the at least one processor, the memory, the RFID reader and the motion sensor;
wherein at least one of the light source, the power reserve, the motion sensor and the RFID reader are coupled to an electricity source, the light source configured to activate when electricity is provided via the electricity source;
wherein the at least one processor is configured to activate the RFID reader when the motion sensor detects motion; and
wherein the RFID reader is configured to emit interrogator signals when activated by the at least one processor.

Abstract
Disclosed are various embodiments for a light bulb or other type of lighting fixture that integrates a light source and a radio frequency identification (RFID) reader. Embodiments of the disclosure can also forward identifiers corresponding to RFID tags detected by the RFID reader to another computing device that can facilitate identification of products or items associated with the RFID tags. RFID tags are energized with interrogator signals and/or an electromagnetic field emitted from the RFID reader and submit a response, which can be forwarded, or data extracted and transmitted, to another computing device.
