Claim of US Patent No. 9,967,928

1. A driver module of a lighting fixture for coupling to a separate light engine module, the separate light engine module being a replacement for a prior light engine module of the lighting fixture and having a solid-state light source and light engine memory, the driver module comprising:a local memory; and
a control circuitry associated with the local memory and adapted to:
retrieve replacement data from the light engine memory;
retrieve drive data from the light engine memory of a light engine module when the replacement data indicates that the separate light engine module of the lighting fixture is the replacement for the prior light engine module of the lighting fixture, wherein drive signals configured to control how the driver module drives the solid-state light source to generate light with at least one lighting characteristic are derived from the drive data;
drive the solid-state light source of the separate light engine module based on the drive data; and
set the replacement data in the light engine memory to indicate that the replacement light engine module is no longer a replacement for the prior light engine module of the lighting fixture.
