Auto dim and color adjusting backlight for a wall mounted control device

A system for providing backlighting or light indication for a lighting load control device comprising:

• at least one button associated with at least one LED;
• a light sensor adapted to detect light and output light level readings;
• a memory comprising a day/night light level threshold;
• and
• at least one controller that:
• receives a day color setting, a night color setting, a minimum intensity setting, and a maximum intensity setting;
• determines at least one dimming curve using the minimum intensity setting and the maximum intensity setting, wherein the at least one dimming curve is represented by a relationship between light level readings and intensity levels;
• drives the at least one LED at the night color setting when the received light level reading is below the day/night light level threshold;
• drives the at least one LED at the day color setting when the received light level reading is above the day/night light level threshold;
• and
• drives the at least one LED at an intensity level determined using a light level reading received from the light sensor and the at least one dimming curve.

A system for providing backlighting or light indication comprising:

• at least one controller that receives a day color setting, a night color setting, a minimum intensity setting, and a maximum intensity setting, and determines a day dimming curve and a night dimming curve using the minimum intensity setting and the maximum intensity setting, wherein the day dimming curve and the night dimming curve are each represented by a relationship between light level readings and intensity levels;
• and
• a lighting load control device comprising at least one button associated with at least one LED, a light sensor adapted to detect light and output light level readings, and a memory comprising a day/night light level threshold, wherein the lighting load control device:
• drives the at least one LED at the night color setting and an intensity level determined using the night dimming curve when the received light level reading is below the day/night light level threshold;
• and
• drives the at least one LED at the day color setting and an intensity level determined using the day dimming curve when the received light level reading is above the day/night light level threshold.

A lighting load control device comprising:

• a memory storing a day/night light level threshold, a day color setting, a night color setting, and at least one dimming curve represented by a relationship between light level readings and intensity levels, wherein the at least one dimming curve is determined using a minimum intensity setting input and a maximum intensity setting input;
• at least one button associated with at least one LED;
• a light sensor adapted to detect light and output light level readings;
• and
• a controller that:
• drives the at least one LED at the night color setting when the received light level reading is below the day/night light level threshold;
• drives the at least one LED at the day color setting when the received light level reading is above the day/night light level threshold;
• and
• drives the at least one LED at an intensity level determined using a light level reading received from the light sensor and the at least one dimming curve.

A method for providing backlighting or light indication to a lighting load control device having at least one button associated with at least one LED, a light sensor adapted to detect light and output light level readings, and a memory comprising a day/night light level threshold, the method comprising the steps of:

• determining at least one dimming curve using the minimum intensity setting and the maximum intensity setting, wherein the at least one dimming curve is represented by a relationship between light level readings and intensity levels;
• driving the at least one LED at the night color setting when the received light level reading is below the day/night light level threshold;
• driving the at least one LED at the day color setting when the received light level reading is above the day/night light level threshold;
• and
• driving the at least one LED at an intensity level determined using a light level reading received from the light sensor and the at least one dimming curve.
