LED-BASED ILLUMINATION SYSTEMS HAVING SENSE AND COMMUNICATION CAPABILITY

摘要

An LED based illumination device includes a plurality of LEDs (162) that emit light through an output port of a housing (103). The LED based illumination device includes a heat sink (101) that is in thermal contact with the plurality of LEDs (162). A peripheral electrical circuit board (130) is configured to be contained within the housing (103), e.g., surrounding at least a portion of the heat sink (101). The peripheral electrical circuit board (130) may include a radio frequency (RF) transceiver configured to communicate data between the LED based illumination device and another electronic device. A primary electrical circuit board (120) may be electrically coupled to the peripheral electrical circuit board (130) and electrically coupled to the plurality of LEDs (162).
