A body (10) is disclosed for obscuring a light source arrangement (3). The body comprises a surface (20) including a plurality of optically reflective relief structures (30, 30, 30), each relief structure comprising a first portion (31) and a second portion (33) adjacent to said first portion extending from said surface, wherein the first portion has a different optical reflectivity to the second portion and neighboring optically reflective relief structures are separated by an optically transparent medium contacting said neighboring optically reflective relief structures. Also disclosed is a luminaire comprising such a body and a method of manufacturing such a body.

The present invention discloses an assembled lamp cover comprising: an unfoldable and curable cover body, an annular upper holder, and a lower holder. Due to the fact that the cover body is unfoldable and curable, and the upper holder and the lower holder can be separated into a plurality of smaller parts, the size of the present invention after being separated becomes extremely small, taking up less space, convenient to package, store and carry in the later period; especially, since the unfoldable and curable cover body, even if collision or extrusion occurs in the carrying process, damage cannot be caused, saving transportation cost.

A light shade can include a top surface formed by a plurality of adjacent, alternating peak and trough folds that define intervening facets, a bottom surface disposed opposite the top surface, and an edge surface transverse to and connecting the top surface and the bottom surface. The intervening facets can each be in the shape of a triangle with adjacent triangular facets sharing an edge. The shared edge can be one of a peak fold or a trough fold. One or more of the trough folds can have a plunge between the edge surface and an opposing side of the top surface. In an implementation, the light shade can be manufactured from a unitary polymeric sheet with the bottom surface being a mirror image of the top surface.
