Abstract:
A light modifying apparatus comprising:a. a housing of roughly trapezoidal cross section, having an open larger parallel side, a smaller parallel side and a plurality of in line, spaced apart holes in said smaller parallel side; said open larger parallel side and said smaller parallel side being of approximately equal length; said housing also having angled faces joining said parallel sides along said length and end faces joining said parallel sides perpendicularly at their ends; said in line, spaced apart holes adapted for receiving lamp heads and lenses;b. a flange at the perimeter of said larger parallel side of said housing;c. a rigid frame, of approximately the same size as said flange, attached to said flange; said frame having an opening through it of approximately the same size as said open larger parallel side of said housing;d. a light baffle, of roughly trapezoidal cross section having an open larger parallel side, attached with its open larger parallel side facing the smaller parallel side of said housing, across said rigid frame; the length of said light baffle being the same as the length of said parallel sides of said housing; the width of said light baffle being approximately the same as the width of the smaller parallel side of said housing; the length of said light baffle being aligned with said in line, spaced apart holes; said light baffle being made or a light reflective material;e. yoke means attached to said end faces for adjustably mounting said housing on a stand;f. a liner of a size and shape to fit snugly inside said housing, and having a plurality of holes of the same size as and located to be in registration with those in said smaller parallel side of said housing; said liner being made of light reflective material and attached to the inside of said housing; andg. an adapter plate; said adapter plate being approximately the same size as said smaller parallel side and having a plurality of holes of the same size as and located to be in registration with those in said smaller parallel side; said adapter plate being adapted for mounting of said lamp heads or lenses through said holes in said adapter plate, said smaller parallel side and said liner; andh. means for detachably attaching said adapter plate to said a rear of said smaller parallel side.
