Abstract: A portable lamp assembly includes a spine member, a first and second side panel rotatably connected to the spine member, and a pair of first and second tangent links prismatically and rotatably operably coupled to the first and second side panel. Each of the tangent links has a plurality of vertical adjustment positions disposed between an upper and lower portion. The spine member and the first and second side panels have at least one source of light connected thereto. The first side panel and the second side panel can be rotated between an open position to allow the sources of light emit light towards a target area and a closed position for storage of the portable lamp assembly. The portable lamp assembly is free standing in the open position to allow the portable lamp assembly to be used without any external support.
