Dual edge coupler

A luminaire, comprising:

• a first waveguide having a first coupling surface;
• a second waveguide having a second coupling surface;
• a coupling optic disposed adjacent to the first coupling surface and the second coupling surface and adapted to receive a light source, the coupling optic comprising:
• a central coupling section;
• a first light distribution section;
• and
• a second light distribution section opposed to the first light distribution section,
• wherein each of the first and second light distribution sections includes a first surface having a curved portion and a planar portion both bounded by a second surface and a third surface, and wherein the curved portion is proximal to the central coupling section and the planar portion is distal from the central coupling section.

A luminaire, comprising:

• a second waveguide having a second coupling surface;
• a coupling optic disposed adjacent to the first coupling surface and the second coupling surface and adapted to receive a light source, the coupling optic comprising:
• a central coupling section including a central cavity defined by a substantially conical coupling surface disposed adjacent to a substantially cylindrical coupling surface;
• a first light distribution section;
• and
• a second light distribution section opposed to the first light distribution section.
