Control device having an integral reflecting structure for a sensing circuit

A method to control illumination an electrical load control device including a plurality of buttons, a faceplate at least partially surrounding the plurality of buttons, and a housing insertable into a wallbox, the method comprising:

• receiving, by control circuitry from a sensor positionable between the faceplate and the housing, a sensor signal that includes data representative of at least one sensed ambient environmental parameter about the electrical load control device;
• retrieving, by the control circuitry from communicatively coupled memory circuitry, data representative of an active button illumination parameter based on the at least one sensed environmental parameter;
• retrieving, by the control circuitry from the memory circuitry data representative of an inactive button illumination parameter based on the at least one sensed environmental parameter;
• causing, by the control circuitry, a first backlight circuit that includes one or more light-emitting diodes (LEDs) to illuminate an active button using the retrieved active button illumination parameter responsive to an actuation of the active button;
• and
• causing, by the control circuitry, a second backlight circuit that includes one or more LEDs to illuminate at least one inactive button using the retrieved inactive button illumination parameter responsive to the actuation of the active button.

A non-transitory, machine-readable, storage device that includes instruction that, when executed by control circuitry included in a wallbox-mountable electrical load control device, causes the control circuitry to:

• receive a sensor signal from communicatively coupled sensor circuitry;
• retrieve, from communicatively coupled memory circuitry, data representative of an active button parameter based on the at least one sensed environmental parameter;
• retrieve, from the memory circuitry data representative of an inactive button parameter based on the at least one sensed environmental parameter;
• cause a first backlight circuit that includes one or more light-emitting diodes (LEDs) to illuminate an active button using the retrieved active button backlight intensity responsive to an actuation of the active button;
• and
• cause a second backlight circuit that includes one or more LEDs to illuminate at least one inactive button using the retrieved inactive button backlight intensity responsive to the actuation of the active button.
