    Abstract: A controller for a light fixture includes light intensity control circuitry to control intensity of light and color temperature control circuitry to control color temperature of light produced by a light engine, a first switch having a first switch cover disposed on an exterior portion of the controller, the first switch configured to communicate with the light intensity control circuitry to cause the light engine to produce a specified light intensity based on a position of the first switch cover, and a second switch having a second switch cover disposed on the exterior portion of the controller, the second switch configured to communicate with the color temperature control circuitry to cause the light engine to produce a specified color temperature of light based on a position of the second switch cover. The position of the first switch cover and the position of the second switch cover are manually selectable.

    Abstract: A controller assembly for a light fixture may include a controller housing to be received within a knockout opening of a light fixture housing from which light is emitted, and a user input assembly positioned within the controller housing. The user input assembly may include a mechanical actuator accessible through a controller opening in the controller housing, and a connector interface to be electrically connected by wiring to a driver of the light fixture, and circuitry electrically coupled to the mechanical actuator and the connector interface. The circuitry may be used to detect actuation of the mechanical actuator by a user and, in response, change a control signal from the connector interface to the driver from a first control signal to a second control signal in order change a property of the emitted light.

    Abstract: A light fixture controller is configured for controlling the color temperature and intensity of a light fixture that includes at least two LED groups. Each LED group includes multiple LEDs configured to produce light at certain color temperatures. The light fixture controller receives a color temperature setting and an intensity setting for the light fixture and generates control signals based on these settings. A first control signal only turns on the first LED group for a first duration of a cycle and a second control signal only turns on the second LED group for a second duration of the cycle. The ratio between the first and second duration is determined based on the color temperature setting. The control signal further includes a dimming control signal for controlling a current flowing through the LED groups based on the intensity setting for the light fixture.
