Light Tower Diffuser

A light diffuser for use with a light tower equipped with a T-bar, crossbar or similar light support, comprising:

• an upper bracket, wherein said upper bracket lies in a generally horizontal plane;
• a lower ring generally parallel to said upper bracket, wherein said lower ring lies in a plane generally parallel to said upper bracket, wherein said lower ring and said upper bracket are generally positioned such that said upper bracket is above said lower ring such that said upper bracket and said lower ring have a generally vertical central axis plane running generally through the center of said upper bracket and generally through the center of said lower ring;
• wherein said upper bracket is positioned above said T-bar, crossbar or similar light support of said light tower and said lower ring is positioned below said T-bar, crossbar or similar light support of said light tower;
• a plurality of flexible rod assemblies connecting said upper bracket and said lower ring, said plurality of flexible rod assemblies forming a support structure between said upper bracket and said lower ring, said support structure expandably configured such that when said lower ring and said upper bracket are at a furthest apart position, said flexible rod assemblies are in a generally straight position, and when said lower ring and said upper bracket are moved closer together, said flexible rod assemblies flex outward to form a generally spherical or generally ellipsoidal shaped frame, when the lower ring is lowered said rod assemblies straighten around said support T-bar, crossbar, or similar light structure such that said support T-bar, crossbar, or similar light structure does not interfere with said straightening of said rods;
• an envelope of light diffusing material removably fastened to said upper bracket and said lower ring and encapsulating said plurality of flexible rod assemblies, said envelope supported by said plurality of flexible rod assemblies, said plurality of flexible rod assemblies and said envelope forming a generally spherical or ellipsoidal light diffuser when said lower ring is moved closer to said upper bracket;
• and
• a pulley and cable assembly operatively connected to said lower ring, wherein said pulley and cable assembly is configured and positioned to move said lower ring closer to said upper bracket and further from said upper bracket by raising and lowering said lower ring.

A light diffuser for use with a light tower equipped with a T-bar, crossbar or similar light support, comprising:

• an upper bracket, wherein said upper bracket lies in a generally horizontal plane;
• a lower ring generally parallel to said upper bracket, said lower ring positioned below said upper bracket such that the center of said upper bracket is positioned generally above said lower ring such that said center of said upper bracket and said center of said lower ring lay on generally the same vertical axis plane;
• wherein said upper bracket is positioned above said T-bar, crossbar or similar light support of said light tower and said lower ring is positioned below said T-bar, crossbar or similar light support of said light tower;
• a pulley and cable assembly connected to said lower ring and configured and located such that said pulley and cable assembly raises said lower ring when an operator pulls on a cable and lowers said lower ring when an operator pulls on a second cable to bring said lower ring closer and further from said upper bracket;
• a plurality of flexible rod assemblies connecting said upper bracket and said lower ring, said plurality of flexible rod assemblies forming a support structure between said upper bracket and said lower ring, said support structure expandably configured such that when said lower ring and said upper bracket are at a furthest apart position, said flexible rod assemblies are in a generally straight position and limit the distance apart the upper bracket and lower ring can be from each other, and when said lower ring and said upper bracket are moved closer together, said flexible rod assemblies flex outward to form a generally spherical or generally ellipsoidal shaped frame, said flexible rods assembled such that when said support structure is contracted, said support T-bar, crossbar, or similar light structure does not interfere with said rods;
• a one way hinge located on each of said rod assemblies in said series of rod assemblies;
• and
• an envelope generally spherical in shape with an opening at the top and an opening at the bottom of said envelope, said openings configured to allow air circulation, said envelope removably fastened to said upper bracket and said lower ring and said support structure supports said envelope, wherein said envelope is configured to evenly diffuse light from a light emitting tower and constructed of a fire resistant material.
