摘要

Apparatus, methods and systems for lighting may be provided. Apparatus may include a fixture. The fixture may include a first light-emitting diode (“LED”). The first LED may emit light of a first color. The fixture may include a second LED. The second LED may emit light of a second color. The apparatus may include a light driver circuit. The light driver circuit may operate the fixture in a tunable color mode. The light driver circuit may operate the fixture in a dim-to-warm mode. The light driver circuit may switch between the tunable color mode and the dim-to-warm mode. The light driver circuit may switch between the tunable color mode and the dim-to-warm mode in response to a signal corresponding to a user mode-selection.

說明書

The mode indicator may indicate if a mode includes two inputs. The indication of two inputs may correspond to the tunable color mode. One of the two inputs may include a user-selected CCT level. One of the two inputs may include a user-selected brightness/dimming level. The microcontroller may cause the LEDs to emit a light corresponding to the selected CCT and brightness/dimming level. The microcontroller may cause the LEDs to emit a light in the tunable color mode.

The signal may be initiated by a user command. The user command may include a control message indicating which mode was selected. The control message may include the mode indicator. The mode may be the tunable color mode. The tunable color mode may include a red, green, blue (“RGB”) color mode. The tunable color mode may include a hue saturation value (“HSV”) color mode. The tunable color mode may include a full color spectrum mode. The tunable color mode may include a tunable white mode. The tunable color mode may include any suitable color mode. The mode may be the dim-to-warm mode. The mode may include any suitable mode for controlling LED properties.

Table 2 lists illustrative user commands.
