    Abstract: A lighting system includes an array of domed light emitting diodes covering a surface area of a substrate and two optics for processing emitted light. The first optic includes an inner surface facing the array and an exterior surface facing away from the array. The second optic includes grooves extending away from the array. The inner surface of the first optic can form a cavity that is large relative to the array. For example, the cavity can have a volume exceeding the volume of a cube, where each side of the cube has the surface area of the array.

    Abstract: A motion sensor includes a sensor element to sense a motion, and a controller communicably coupled to the sensor element. The controller is configured to set a detection sensitivity of the motion sensor to a maximum setting of the detection sensitivity. The controller is further configured to decrease the detection sensitivity of the motion sensor upon a detection of the motion until the motion is undetectable by the motion sensor at a decreased setting of the detection sensitivity. The controller is further configured to increase the detection sensitivity of the motion sensor until the motion sensor detects the motion at an increased setting of the detection sensitivity and to set the detection sensitivity of the motion sensor to a new setting based on the increased setting.
