Claim:
A light shelf assembly comprising: two or more support arms spaced apart substantially horizontally along an interior wall of a building, each support arm having a first end and a second end, the first end being secured to the interior wall and the second end extending away from the interior wall and being spaced apart from the interior wall, and each support arm defining at least one channel along an outer surface of the support arm; and at least one light shelf comprising a substantially planar base portion, the base portion having a reflective upper surface, a first side surface and a second side surface, the first side surface being opposite and spaced apart from the second side surface, the at least one light shelf further comprising at least one protrusion that extends outwardly from each of the first and second side surfaces, wherein the at least one protrusion comprises at least a first pivot member and a second portion for each of the first and second side surfaces and wherein a gap is formed between the at least first pivot member and the second portion, wherein: the channel defines an opening that is at least partially within a horizontal plane that extends between two adjacent support arms, the at least one protrusion extending from the first side surface slidably engages the channel of the support arm adjacent the first side surface and the at least one protrusion extending from the second side surface slidably engages the channel of the support arm adjacent the second side surface such that a back edge surface of the base portion is disposed adjacent the first ends of the support arms, a front edge surface of the base portion is disposed adjacent the second ends of the support arms, and the light shelf is suspended between the support arms, and the light shelf is pivotable about the first pivot members when the second portions of the at least one protrusion for each of the first and second side surfaces are slidably disengaged from the channels of the adjacent support arms.
