Light fixture of building automation system
There is described a building automation system comprising a mobile tag, sensor devices, and a sensor hub. The mobile tag transmits a broadcast beacon based on RF technology. The sensor devices are co-located with light fixtures and include antennas for receiving a broadcast beacon. The sensor devices generate signals associated with the broadcast beacon received by the antennas. The sensor hub receives the signals from each sensor device and determines a location of the mobile tag based on the signals.
1. A light fixture comprising:
a light fixture housing including a central portion and opposing ends;
a lamp supported by the light fixture housing, the lamp including a plurality of semiconductor light sources positioned along a linear dimension toward opposing sides of the light fixture housing;
a plurality of antennas supported by the light fixture housing, the plurality of antennas extending from the central portion of the light fixture housing toward the opposing ends of the light fixture housing in parallel to the plurality of semiconductor light sources; and
a sensor component coupled to the plurality of antennas, the sensor component processing RF signals received from a remote device by the plurality of antennas.
2. The light fixture as described in claim 1 , wherein:
the plurality of antennas are positioned within a periphery of the lamp.
3. The light fixture as described in claim 1 , wherein the plurality of antennas are obscured due to at least one of an active state of the plurality of semiconductor light sources or a portion of the light fixture housing.
