Abstract
Abstract This invention is directed at a light box comprising a box-like base member and a cover. The base member has a storage compartment and a series of light chambers which are aligned with the storage chamber. The storage chamber includes a means of providing power to the source of light mounted in the light chambers. The cover is pivotally engaged to the base member by an L hinge and has an adjustable connector extending therefrom which is engageable with the base member. Each of the secondary walls has an upper side edge and a lower side edge. The upper side edge is positioned in close proximity to the opening of the base member and the lower side edge is positioned in spaced parallel relation to the upper side edge and has a notch formed therein. The notches of the secondary walls are in aligned, spaced relation to each other. A first channel is mounted in a shoulder formed at the opening to the base member and faces into the light chambers. A series of inward facing channels are mounted in the light compartment adapted to cooperate with the first channel to hold a filter or the like in parallel relation to the base. The first channel is spaced from the top side edge of the base member providing an opening into the light chambers and the bottom wall of the base member has at least one vent formed therethrough. The base has a platform portion mounted thereon within the storage chamber. The platform portion is spaced from the inner surface of the base and has a connector mounted thereon facing into the storage chamber.
