Abstract

This disclosure describes systems, methods, and apparatus for a customizable and modular LED lighting system. The LED lighting system can include an LED driver coupled to a light run and held rigidly relative to each other via a carrier. A mounting bracket can also attach to the LED driver and/or the light run and can affix the LED lighting system to a junction box. The light run can include a thermally conductive frame, sometimes having a “V”-shape and having two surfaces on an upper portion thereof. A substrate comprising a string of electrically-coupled LEDs can be affixed to each of the two surfaces. The LEDs can be driven by the LED driver and can be coupled to each other serially via one or more electrical connectors.
