Abstract: An apparatus, system, and method for an automatic dimming and color temperature adjusting backlight LEDs of wall mounted control device buttons. The control device comprises a light sensor, a memory, and a controller adapted to control an operation of an associated electrical load. The light sensor detects light levels in a space where the control device is installed and outputs light level readings. The memory stores a color temperature curve represented by a relationship between light level readings and color temperatures. In response to receiving a light level reading from the light sensor, the controller determines a color temperature level using the received light level reading and the color temperature curve, and drives the at least one LED at the determined color temperature level.

Abstract: An apparatus cools electronic circuitry. An enclosure surrounds the electronic circuitry and has plural surfaces. Air intake holes are disposed in at least one surface and face at least one first direction. Air exhaust holes are disposed in at least another surface and face at least one second direction different than the first direction. A heat sink is in thermal contact with the circuitry and conducts heat generated by the circuitry. When a fan operates, air is drawn from an exterior of the enclosure through the air intake holes, absorbs heat from the heat sink, and then is directed through the air exhaust holes into the exterior of the enclosure. The heat sink is further in thermal contact with the enclosure so that when the fan does not operate, heat is drawn from the circuitry to the enclosure via the heat sink and is dissipated from the exterior.
