Abstract
A lighting fixture includes a driver module and a separate light engine module, which has a solid-state light source and light engine memory. The driver module is electrically coupled to the light engine module and configured to drive the solid-state light source based on drive data. The drive data defines how the driver module should drive the solid-state light source to generate light with at least one defined lighting characteristic. The drive data may define or be used to identify the signal characteristics, such as drive currents, voltages, waveforms, and the like that must be provided by the driver module to drive the solid-state light source. The drive data is stored in the light engine memory of the light engine module, and the driver module is configured to retrieve the drive data from the light engine memory and drive the solid-state light source based on the drive data.
