Abstract

An LED-based replacement light comprises multiple LEDs, the LEDs having different logical control addresses associated among them, with each logical control address subjecting one or more of the LEDs associated therewith to individual control; a controller in communication with the LEDs, the controller configured to generate signals that individually control the operating states of the one or more LEDs associated with each logical control address; a housing for the LEDs; and a connector disposed at an end of the housing, the connector shaped for connection with a light socket.

Claims

1-20. -20. (canceled)

21. 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.

22. The LED-based lighting device of claim 21, 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.

23. The LED-based lighting device of claim 21, wherein the one or more first optical devices are associated with the first logical control address, and wherein the one or more second optical devices are associated with second logical control address.

24. The LED-based lighting device of claim 21, wherein each of the one or more first optical devices is configured to direct light in a first common direction, and wherein each of the one or more second optical devices is configured to direct light in a second common direction different than the first common direction.

25. The LED-based lighting device of claim 21, wherein at least one first optical device comprises a first over mold, and wherein at least one second optical device comprises a second over mold.
