Abstract

A color-changing light array powered by a driver circuit, the driver circuit responsive to a controller circuit, and the controller circuit configured to change display lighting patterns or colors based on modes of operation and off-on power cycle intervals.

Claims

1. A device comprising:

a color-changing light array powered by a driver circuit, the driver circuit responsive to a controller circuit and the controller circuit responsive to a user interface, wherein the controller circuit is configured to;

start with an initial mode of operation upon the powering on of the color-changing light array;

provide a visual display of a mode of operation via the color-changing light array;

change the initial mode of operation to a selected mode of operation responsive to a power off-on cycle of the color-changing light array within a range of a first predetermined time interval;

if the selected mode of operation produces a continually cycling display from a set of light patterns or colors, preserve the selected mode of operation, and start the continually cycling display from a predetermined light pattern or color; and

if the selected mode of operation produces selectable displays of static light patterns or colors, preserve, responsive to a color-changing light array power off-on cycle having at least the range of a second predetermined time interval, the selected mode of operation having the last selectable display of light patterns or colors, displayed at a start of the color-changing light array power off-on cycle of the second predetermined time interval, as a static light pattern or color.

2. The device of claim 1 wherein, if the selected mode of operation produces the continually cycling display from the set of light patterns or colors, wherein the controller circuit is configured to preserve the selected mode, responsive to a color-changing light array power off-on cycle having at least the range of the second predetermined time interval, and restart the continually cycling display from the predetermined displayed light pattern or color.

3. The device of claim 1 wherein the controller circuit is configured to reset the modes of operation based on a powering of the color-changing light array off and on within a third predetermined time interval while the controller circuit is in any selected mode of operation;

and restart with the initial mode of operation.

4. The device of claim 2 wherein the second predetermined time interval and the third predetermined time interval are equal.

5. A device comprising:

a color-changing light array powered by a driver circuit, the driver circuit responsive to a controller circuit and the controller circuit responsive to a user interface, wherein the controller circuit is configured to;

set an initial mode of color-changing light array operation to a first mode of color-changing light array operation based on a powering of the color-changing light array;

set the mode of color-changing light array operation to a subsequent mode of color-changing light array operation based on powering off and then powering on the color-changing light array within a first predetermined time interval; and

set a submode of color-changing light operation to a submode of color-changing light operation, after the expiration of the first predetermined time interval.

6. The device of claim 5 wherein the modes of color-changing light array operation comprise at least:

(a) continually cycling displays from the set of light patterns or colors and (b) selectable displays of static light patterns or colors.

7. The device of claim 6 wherein a submode of the mode of the continually cycling display from the set of light patterns or colors comprises starting the continually cycling display from the predetermined light pattern or color.

8. The device of claim 7 wherein the controller circuit is further configured to reset the mode of color-changing light array operation to the initial mode of color-changing light array operation based on powering off and then, within a third predetermined time interval, powering on the color-changing light array.

9. The device of claim 8 wherein the second predetermined time interval and the third predetermined time interval are equal.

10. The device of claim 6 wherein a submode of the mode of the selectable displays of static light patterns or colors comprises a static light pattern or color based on the last selectable display of light patterns or colors, displayed prior to the color-changing light array power off-on cycle of a second predetermined time interval.

11. The device of claim 10 wherein the controller circuit is further configured to reset the mode of color-changing light array operation to the initial mode of color-changing light array operation based on powering off and then, within a third predetermined time interval, powering on the color-changing light array.

12. The device of claim 11 wherein the second predetermined time interval and the third predetermined time interval are equal.
