1. A light fixture for use in an installed panel system comprising;
a) an optical assembly comprising;
i) at least one LED board comprising one or more LEDs mounted and positioned on at least one face of a printed circuit board and further comprising one or more arranged electrical circuits;
ii) at least one reflector or reflective surface;
iii) a primary optical element comprising a bulk light transmissive material and internal or surface light scattering features and further comprising at least one input face and an output face; wherein the primary optical element modifies the light distribution from the at least one LED when light is transmitted through the primary optical element;
b) at least one elongate housing body retaining and aligning the optical assembly comprising;
i) a longitudinally extended 2-dimensional x-y cross-sectional profile shape with two side portions joined by a backplane and configured to position and retain the optical assembly components in optical alignment, and collectively defining an internal cavity extended longitudinally wherein the longitudinal ends of the elongate housing body are cut at configured angles with respect to the longitudinal direction, wherein the lengths of each side portion corresponds to the configured cut angles;
ii) at least one support feature extending from at least one side portion of the elongate housing body and configured to support and conceal the edge of a panel of the installed panel system;
c) at least one end plate or end cap mounted to an end of the elongate housing body to enclose the internal cavity;
wherein the peak intensity and light distribution from the light fixture are configured by selecting the amount of primary optical element light scattering and by controlling the electrical power distributed to the one or more LEDs via the arranged electrical circuits of at least one LED board.
