Abstract: A recessed light fixture, mountable on a wall, includes a trim, heat sink, fasteners and springs. The trim has a trim frame with a trim opening for a light source. The heat sink includes an open end which opens into a cavity to house a portion of the light source, and an interior surface with an interior groove that extends around the interior surface. Each spring has a first end and an opposing second end. The first end of the springs is connected to the trim frame with a fastener. The second end of the springs is inserted through the open end of the heat sink until the second end snaps into and engages the interior groove to connect the heat sink and the trim frame. The second end is movable along the interior groove to allow rotational adjustment of the trim frame relative to the heat sink.

Abstract: System and method for dimming solid-state lighting (SSL) avoids visual anomalies such as flicker for different types of SSL fixtures. This ability to avoid visual anomalies allows the system and method to be compatible with virtually any SSL fixture from any manufacturer. A controller is provided in some implementations that automatically generates a dimming voltage for the SSL fixtures based on a dimming control signal. A skip-phase dimming module is provided in some implementations that operates in conjunction with the controller to automatically skip dimming levels that cause visual anomalies in the SSL fixtures. A wireless module is provided in some implementations to receive signals from remote sensors and other input devices, such as ambient light sensors, occupancy sensors, color sensors, and the like.
