Abstract

In an auto vibrancy mode, a vibrancy value for a lighting load may be automatically determined based on a selected color setting for the lighting load. The automatically determined vibrancy value may also be configured to emit light from the lighting load at or above a target CRI value for the selected color setting. The selected color setting may be a CCT value on the black-body curve or an x-y chromaticity value. If the selected color setting is CCT value on the black-body curve, the automatically determined vibrancy value may be a pre-defined vibrancy value that is configured to emit light from the lighting load at or above the target CRI value for the selected CCT value. If the selected color setting is an x-y chromaticity value, the automatically determined vibrancy value may be based on the distance between the selected x-y chromaticity value and the black-body curve.

First claim

What is claimed is:

1. A method comprising:
receiving system configuration data, wherein the system configuration data defines a plurality of zones, wherein each zone of the plurality of zones is configured to control at least one lighting load comprising a plurality of light emitting diodes (LEDs);
receiving a selection of a first color temperature value of a plurality of color temperature values to which a first zone of the plurality of zones is to be controlled in response to a triggering event for a scene;
receiving a selection of a second color temperature value of a plurality of color temperature values to which a second zone of the plurality of zones is to be controlled in response to the triggering event for the scene;
automatically determining a color rendering index (CRI) value above a threshold based on the selected first color temperature value and the selected second color temperature value;
defining the scene to control the first zone and the second zone of the plurality of zones to the selected color temperature value such that a light output of the at least one lighting load of the first zone and the at least one lighting load of the second zone is controlled at the determined CRI value above the threshold;
detecting the triggering event for controlling the plurality of zones configured for the scene;
generating, in response to the detected triggering event, control instructions configured to control the plurality of LEDs of the at least one lighting load of the first zone and the plurality of LEDs of the at least one lighting load of the second zone to the selected color temperature value such that the light output of the at least one lighting load of the first zone and the at least one lighting load of the second zone is controlled at the determined CRI value above the threshold; and
controlling the plurality of LEDs of the at least one lighting load of the first zone and the plurality of LEDs of the at least one lighting load of the second zone based on the generated control instructions.

2. The method of claim 1 , wherein the received selection of at least one of the first color temperature value or the second color temperature value is received via a button press on a remote control device.

3. The method of claim 1 , wherein controlling the plurality of LEDs of the at least one lighting load of the first zone and the plurality of LEDs of the at least one lighting load of the second zone comprises transmitting at least one message configured to control the at least one lighting load of the first zone and the plurality of LEDs of the at least one lighting load of the second zone.

4. The method of claim 1 , wherein the plurality of LEDs of the at least one lighting load of the first zone comprises a red LED, a green LED, a blue LED, and a white or substantially white LED, and wherein the plurality of LEDs of the at least one lighting load of the second zone comprises a red LED, a green LED, a blue LED, and a white or substantially white LED.

5. The method of claim 1 , the method further comprising:
receiving a selection configured to change a lighting intensity value of the plurality of LEDs of the at least one lighting load of the first zone or the plurality of LEDs of the at least one lighting load of the second zone;
