Abstract

A lighting system includes a lighting device that further includes a housing, and light emitting diode (LED) modules positioned in an opening of the housing to emit light away from the housing. Each LED module includes a substrate, a plurality of module-level conductors, and a plurality of LED sets, each of which comprises a first section including a first group of LEDs, one or more additional sections (each including an additional group of LEDs), a first conductive element that electrically connects the first section to a first one of the module-level conductors, and one or more additional conductive elements. The lighting system also includes control circuitry configured to generate commands to control drive currents delivered to a first group of LEDs in each LED set and each additional group of LEDs in each LED set so that the lighting device emits light of a specified color temperature.
