<p>#CMT# #/CMT# The film (1) has a microstructure (12) on a side (112) of a film base (11), where the microstructure includes a surface (121) inclined at an angle to a reference plane that is perpendicular to the film base. An output angle of an incident light beam (30) passing through the film is defined at 180 degrees if the outgoing light beam is upward directed and is parallel to the film, where total energy of the outgoing light beams with the output angles of 85 to 120 degrees is more than 40 percent of the total energy of the outgoing light beams with output angles of 0 to 180 degrees. #CMT# : #/CMT# An independent claim is also included for a window system comprising a protection plate. #CMT#USE : #/CMT# Light guide film for altering the direction of incident sunlight in a window system (claimed) of a room. #CMT#ADVANTAGE : #/CMT# The film allows incident sunlight beam to be fed horizontally into a space in a room through a window system while obviating dazzling. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the light guide film. 11 : Film base 12 : Microstructure 30 : Incident light beam 31 : Deflected light beam 112 : Side of film base 121 : Surface of microstructure #CMT#INORGANIC CHEMISTRY : #/CMT# The microstructure is formed from a transparent metal oxide such as titanium oxide or tantalum pentoxide.</p> |
