Classification: CPC F  G | IPC F

Claim 0:
1. a light fixture providing a direct downlighting light distribution comprising;
A) an optical assembly comprising;
1) an optical element comprising;
a) a bulk light transmissive material and further comprising light scattering features;
b) an extended profile shape comprising a cross sectional profile area of x-y axes extended in length orthogonally into a z-axis, further comprising;
(i) at least 3 specific faces, all extended in and substantially parallel with the z-axis, namely; an input face into which light is received, an inner opposing face adjacent to the input face, and an outer output face;
(ii) a cross-sectional height defined by the y-axis distance between the inner opposing face and the outer output face;
(iii) a cross-sectional width defined by the x-axis distance;

2) at least one LED board positioned proximate to the input face and comprising at least one LED light source mounted onto a printed circuit board (PCB);
3) at least one reflector mounted adjacent to the optical element inner opposing face such as to redirect light exiting from the optical element back into the optical element inner opposing face

B) a housing having an extended profile shape with extended support feature with which the optical element is positioned and retained in optical alignment with the at least one LED board;
wherein a portion of light from the optical element input face is directly transmitted through the outer output face and a portion of light internally reflects from the outer output face and is propagated within the optical element such that a portion of said light is subsequently outer output from the inner opposing face whereupon it is reflected back into the optical element by the reflector such that the overall resultant light distribution from the optical element outer output face is substantially off axis with at least one peak intensity oriented at an oblique angle to the outer output face.
