LED LUMINAIRE FOR ILLUMINATING A TARGET PLANE.

摘要

A luminaire includes a plurality of LEDs and an optic arranged with respect to the LEDs to redirect light emanating from the LEDs toward a target plane. Centers of each LED are positioned along the perimeter of a bounded plane and are intersected by an LED curve that is coplanar with the bounded plane. The optic includes a light redirecting surface offset from the LED curve. The light redirecting surface cooperates with each of the LEDs and is shaped to redirect light emanating from the LED curve in a direction angularly offset less than 90° from a line normal to the target plane. A method for designing a luminaire to illuminate a target plane is also disclosed.
