Control device having an integral reflecting structure for a sensing circuit
First Claim
1. A control device comprising:
- a faceplate having an indicia;
a light source located behind the faceplate that is configured to backlight the indicia;
a light detector circuit that is configured to measure a light level of ambient light that is external relative to the control device;
a control circuit that is configured to cause the light source to backlight the indicia in accordance with the measured light level; and
an enclosure that houses the light detector circuit, the enclosure including an integral reflector that is configured to direct the ambient light to the light detector circuit.

Abstract
A wall-mounted keypad may include a light detector circuit located inside the keypad that is configured to measure an ambient light level in a space. The light detector circuit may receive ambient light through an aperture that is hidden from view by the keypad. The keypad may include a reflector for directing ambient light onto the light detector circuit. The keypad may include an enclosure that houses the light detector circuit. The enclosure may define a recess that exposes at least a portion of the light detector circuit. The enclosure may include a reflector that may focus ambient light received through the aperture onto the light detector circuit. The keypad may include a control circuit that may be configured to illuminate the indicia of respective buttons of the control device in response to actuations of the one or more buttons, in accordance with the measured ambient light level.
