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 a sensor and a control circuitry configured to generate commands to control drive currents delivered to the first group of LEDs in each LED set and each additional group of LEDs in each LED set based on the data collected by the sensor.
