Abstract
A light bulb or other lamp device incorporating improved antenna configurations and integrated networking equipment is described herein. In one example, a LED light bulb is arranged to include a wireless transceiver and related wireless network processing circuitry, and is coupled to multiple antennas configured to receive and transmit signals using spatial diversity, beamforming, multiple-input and multiple-output (MIMO), or other multi-antenna techniques. The heat sink in the light bulb may be purposed to provide one or more of the multiple antennas, such as use of respective heat sink structures to serve as a diversity antenna. The wireless network processing circuitry may be used for control of the light bulb or for operability with wireless and non-wireless networks. For example, the network processing circuitry may operate as a wireless network access point, repeater, relay, bridge, or like function.
