SYSTEM AND METHOD FOR CONTROLLING OPERATION OF AN LED-BASED LIGHT

iLumisys, Inc., Troy, MI...

1. A lighting system comprising:a first light source having a first communications device associated therewith, the first communications device being configured to transmit a location signal;
a control unit remote from the first light source, the control unit comprising a processor configured to:
store data regarding a plurality of physical areas, the data comprising, for each physical area:
a definition of the physical area, wherein the definition of the physical area comprises at least one of an indication of a functional characteristic of the physical area, an indication of a physical surrounding of the physical area, an indication of a presence of natural light in proximity to the physical area, or an indication of a constraint associated with the physical area, and
an indication of a lighting condition associated with the physical area;
receive the first location signal;
determine that the first light source is positioned within a first physical area of the plurality of physical areas based on the location signal;
store an indication of an association between the first light source and the first physical area;
retrieve the indication of the lighting condition associated with the first physical area; and
operate the first light source to satisfy the lighting condition associated with the first physical area, wherein operating the first light source comprises transmitting one or more command signals to the first communications device associated with the first light source.

LED-BASED LIGHT WITH ADDRESSED LEDS

iLumisys, Inc., Troy, MI...

1. An LED-based lighting device, comprising:one or more first LEDs associated with a first logical control address;
one or more first optical devices configured to distribute light emanating from the one or more first LEDs in a first way;
one or more second LEDs associated with a second logical control address;
one or more second optical devices configured to distribute light emanating from the one or more second LEDs in a second way different than the first way;
a controller in communication with the one or more first LEDs and the one or more second LEDs, wherein the controller configured to generate:
a first control signal to individually control operating states of the one or more first LEDs, and
a second control signal to individually control operating states of the one or more second LEDs;
a housing enclosing the first one or more first LEDs and the one or more second LEDs; and
a connector disposed at a first end of the housing, wherein the connector is shaped for connection with a light socket,
wherein the LED-based replacement light is configured to emanate light from the one or more first LEDs according to a first spatial distribution profile, and emanate light from the one or more second LEDs according to a second spatial distribution profile different from the first spatial distribution profile.
