1. A lighting module configured for use in a suspended ceiling grid assembly comprising;
a) an optical assembly comprising;
i) an edgelit optical element;
ii) a printed circuit board upon which is mounted at least one LED light source;
b) a reflector or an internal reflective surface positioned proximate to a non-input face of the edgelit optical element;
c) a linear support element comprising an elongate body in the form of a 3-dimensional shape of a cross-sectional profile area with internal and external support features extended linearly into a 3rd axis wherein the internal support features retain and maintain alignment of the component parts of the optical assembly and wherein the external support features are configured to facilitate one or more functions of;
i) mounting to a T-Bar within a suspended ceiling grid;
ii) supporting an optical assembly or components thereof;
iii) supporting at least one edge of at least one ceiling panel;
wherein the lighting module is configured to support the edge of a ceiling panel at a height above or below the ceiling grid plane of the suspended ceiling grid arrangement with the panel further being in a parallel or inclined orientation with respect to the ceiling grid plane and;
wherein the internal support features of the linear support element are configured to allow optical components of the optical assembly to be slid along the 3rd axis into position of retainment and alignment.
