Replaceable lighting fixture components
First Claim
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.

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.

15. A light engine module of a lighting fixture for coupling to a separate driver module of the lighting fixture, the light engine module comprising:
-
a mounting structure; a solid-state light source mounted on the mounting structure; and a light engine memory mounted on the mounting structure and accessible by the driver module once the driver module is electrically coupled to the light engine module, the light engine memory comprising; drive data where 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; and replacement data that indicates whether or not the light engine module is a replacement light engine module for the lighting fixture, wherein the replacement data is configured to be modified by the driver module such that the replacement data is modified to indicate that the replacement light engine module is no longer the replacement light engine module of the lighting fixture. - View Dependent Claims (16, 17, 18, 19, 20)

21. A lighting fixture comprising:
-
a location for a light engine module having a solid-state light source and light engine memory; and a 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 the light engine module when the replacement data indicates that the light engine module attached at the location is a replacement of another light engine module previously attached at the location, 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 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. - View Dependent Claims (22)

23. A replacement driver module for a lighting fixture that comprises a separate light engine module with a solid-state light source and light engine memory, the replacement driver module comprising:
-
a local memory that stores pairing information indicative of whether the replacement driver module has been paired with the separate light engine module; and a control circuitry associated with the local memory and adapted to; retrieve the pairing information from the local memory; retrieve drive data from the light engine memory when the pairing information indicates that the replacement driver module is a replacement driver module of another driver module of the lighting fixture, wherein drive signals configured to control how the replacement driver module drives the solid-state light source to generate light with at least one lighting characteristic are derived from the drive data; modify replacement data in the light engine memory when the light engine memory replacement data indicates the separate light engine module is a replacement, wherein the replacement data is modified to no longer identify the separate light engine module as a replacement light engine module; and drive the solid-state light source of the light engine module based on the drive data. - View Dependent Claims (24, 25)
