Patent ID: 7828458

Claim:
An apparatus comprising: a flexible device having a first side, a second side shaped substantially similarly to the first side, an outer edge, a first joining edge, and a second joining edge, the flexible device being approximately flat with the first and the second sides disposed opposite one another such that the outer edge joins the first side and the second side along a substantial portion of a perimeter of the first side and the second side, the first joining edge and the second joining edge defining a gap such that the outer edge does not continue uninterrupted around the entire perimeter of the flexible device, the flexible device flexing to form an assembled structure in which the first joining edge is disposed proximate to the second joining edge, the assembled structure comprising an inner volume having a first opening that is defined by the outer edge and an apex disposed opposite the first opening, the apex having a smaller cross sectional area than the first opening, the first side forming an inner surface of the assembled structure and the second side forming an outer surface of the assembled structure; an adjustable carrying strap at the apex; joining means for connecting the first joining edge and the second joining edge; and attaching means for securing a portable light source to the assembled structure to direct light from the portable light source in a desired manner, the portable light source having an elongated shape along a first axis and emitting light both in the directions of the first axis and perpendicular to the first axis.
