Abstract: A modular lighting fixture and a modular lighting system utilizing the modular lighting fixture, other lighting fixtures, and interchangeable components of lighting fixtures. The configuration of the modular lighting fixture can vary, and the modular lighting system can use one or more variations of the modular lighting fixture(s) and/or components thereof. When installed in an environment, the modular lighting fixture can be adjusted to satisfy aesthetic and functional preferences and requirements in the environment by employing interchangeable components. In some examples, multiple lighting fixtures of differing configurations can be used to create a lighting system that is functional and aesthetically pleasing.

Abstract: Recessed lighting systems are provided including a housing defining an interior cavity, a light emitting module positioned inside the interior cavity and including a heat sink, a circuit board stacked on the heat sink, a light source mounted at a center of the circuit board, driver circuitry for powering the light source, and a cover stacked on the circuit board including a channel for enclosing the driver circuitry and an opening defined such that the light source is not covered by the cover, and a trim assembly installed in the housing including a reflector, a trim having a light guide portion and a decorative trim extending from the light guide portion, and a plurality of interface elements extending from an exterior surface of the reflector or an exterior surface of the light guide portion, the interface elements configured to retain the trim assembly in the housing.
