摘要:
An LED based illumination device includes a receiver and a transmitter for communications adhering to a lighting control communications protocol and a high speed communications protocol. The LED based illumination device may be part of a lighting control network, wherein the data transmission rate of the high speed communications protocol is more than twice that of the lighting control communications protocol. The lighting control network may be coupled to a digital communications gateway, including a digital communications interface configured to be coupled to a network operating in accordance with an internet protocol and a lighting control network interface coupled to the lighting control network. A processor determines a summary status value of the LED based illumination device based on information stored in memory of the digital communications gateway. The digital communications gateway may periodically transmit the time of day to the LED based illumination device over the lighting control network.

An LED based illumination device (200) includes a plurality of LEDs that emit light through an output port of a housing (103). The LED based illumination device (200) includes a heat sink (101) that is in thermal contact with the plurality of LEDs. 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 (135) configured to communicate data between the LED based illumination device (200) 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.

摘要:
A reflector housing is detachably coupled to an LED based illumination device and includes a flange having a surface facing the environment illuminated by the LED based illumination device. The reflector housing further includes a reflector having an input port that receives light emitted from the LED based illumination device and an output port through which light passes toward the environment. At least one sensor, such as a sensor for occupancy, an ambient light, a temperature, ultrasound, vibration, pressure, or a camera, microphone, visual indicator, or photodetector, is coupled to the flange such that at least a portion of the sensor faces the environment illuminated by the LED based illumination device. A reflector interface module configured to receive at least one signal from the sensor is coupled to the reflector housing. Additionally, a communications interface subsystem is configured to transmit and receive communications signals to and from the reflector housing.
