A mounting assembly for mounting a light pipe lighting system on a support surface includes an elongate support rail connect to the light source and a hanger bracket connect to the elongate support rail. The support rail includes oppositely extending longitudinal flange portions which slidably engage the hanger bracket and thereby serve to connect the support rail with the hanger bracket. The hanger bracket can be either slidably supported on the support rail to allow the light source to move relative to the support surface or the hanger bracket can be fixed at various locations along the support rail. The elongate light source support rail is connect to the light source with a bracket or with a casing which encloses the light source, and the light source support rail can be further connected with an associated light pipe support rail to transmit axial forces between the light pipe and light source.
