Light

A shade control arrangement comprises a shade panel having inner and outer edges with an attachment clamp or attachment clips at the inner edge and additional clips at the outer edge. The outer clips can be used to hold the edge of a gelatin sheet or a perforated sheet to stretch the sheet across a source of light to which a pair of panels is connected using the inner clips or clamp. The clamp comprises inner and outer jaws which form a pocket that can be closed with a screw, at least one of the jaws being pivotally connected between the legs of a U-shaped fork that is detachably connected to the shade panel near the inner edge thereof. A flexible shaft is detachably connected to the clamp. A similarly structured clamp can be used to capture the edge of a flexible sheet that contains a plurality of parallel bend troughs so that the sheet can be bent into a variety of shapes. The arrangement also includes an articulated shade device which comprises a base plate to which are pivotally connected a pair of articulated arms. Each arm is made of rectangular arm segments that are connected to each other in series.

Shadow control system

A shade panel assembly comprises an opaque flexible shade panel having opposite surfaces and made of a material which can be easily cut into different shapes. Non-glare, low reflection markings are provided on both surfaces to guide the cutting of the panel into a plurality of rounded leaves for providing guides to produce custom-shaped leaves.

A collapsible fluorescent tube fixture comprises a frame having a pair of spaced apart tube end supports each carrying a row of sockets, each socket being for receiving electrodes of one end of a fluorescent tube, and a scissors assembly connected between the supports for permitting the supports to move together into a storage position and to accommodate various length tubes and apart into a use position. Fluorescent tubes can be engaged between the sockets of the two supports with the supports in their use position. A boom has one end connected to the scissors assembly and an opposite end which carries an electrical ballast. The ballast is electrically connected to the sockets and may serve not only to electrically ballast the fluorescent tube but also to mechanically balance the weight of the frame. A pivot clamp connected intermediate the ends of the boom can be used to mount the boom on a tripod or other support structure.
