Abstract

A LED lighting device includes LEDs operable to emit light when powered through an electrical path. The LED lighting device includes a housing and a communications module for wireless communication to and from the LED lighting device. An antenna for receives and transmits a wireless signal where the antenna comprises a slot in the housing. A power supply in the electrical path for providing power to the LEDs may be retained in the housing. The communications module may be retained in the housing with the power supply. The housing may form part of the LED lighting device structure such as a reflector surface.

Claims
