Inventorship Gary Van Winkle, Chagrin Falls, OH (US)
Assignee ETi Solid State Lighting Inc., Wheeling, IL (US)

Claim of US Patent No. 10,462,871

1. An LED light fixture comprising:at least two groups of LEDs, each of said at least two groups of LEDs being electrically coupled together for emitting illumination of a particular correlated color temperature different from the correlated color temperature of said other of said at least two groups of LEDs in response to receiving electric power, at least a respective one of said LEDs being incorporated in at least one of said at least two groups of LEDs;
electrical circuitry including at least three electrical circuits, each of said at least three electrical circuits including at least one group of said at least two groups of LEDs and at least one selected combination of said at least two groups of LEDs;
electrical switching components for each of said at least three electrical circuits, said electrical switching components being actuated for connecting a selected one of the group consisting of said at least two groups of LEDs and said at least one selected combination of said at least two groups of LEDs in one of said electrical circuits to electrical power to effect the emission of illumination of at least one of said at least three values of correlated color temperatures; and
a controllable correlated color temperature switching assembly to actuate a selected one of said electrical switching components to connect a selected group of one of said at least two groups of LEDs and said at least one selected combination of said at least two groups of LEDs to electrical power to cause said selected group of LEDs to emit illumination of the particular correlated color temperature of said selected group of LEDs, said controllable correlated color temperature switching assembly including a digitally operated switch actuating member for actuating said controllable correlated color temperature switching assembly; and
a switch holding structure for holding for operation said digitally operated switch actuating member.
