Abstract
A variety of luminaire modules are disclosed that are configured to output light provided by multiple light-emitting elements (LEEs). In general, embodiments of the luminaire modules feature at least two LEEs disposed on at least one substrate, at least two light guides that receive light from corresponding LEEs of the at least two LEEs, and at least one optical extractor that receives light from corresponding light guides from the at least two light guides.

39. A luminaire module comprising:
-
a first set of light-emitting elements (LEEs) disposed on one or more substrates and adapted to emit light in a forward direction; a second set of LEEs disposed on the one or more substrates and adapted to emit light in the forward direction, the second set of LEEs being independently controllable from the first set of LEEs; a first light guide shaped to guide light, emitted by the first set of LEEs and received at an input end of the first light guide, in the forward direction toward an output end of the first light guide as first guided light; and a second light guide optically shaped to guide light, emitted by the second set of LEEs and received at the input end of the second light guide, in the forward direction toward an output end of the second light guide as second guided light, wherein the first and second light guides are spaced apart forming a space between the first and the second light guide, and one or more portions of the first light guide and the second light guide are optically connected such that a fraction of the first guided light is transmitted from the first light guide via the one or more connected portions to the second light guide, and a fraction of the second guided light is transmitted from the second light guide via the one or more connected portions to the first light guide, wherein the first light guide is configured to provide, at its output end, first mixed light including the first guided light and the fraction of the second guided light, and wherein the second light guide is configured to provide, at its output end, second mixed light including the second guided light and the fraction of the first guided light. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
