Abstract:
A light diffuser for directing light emitted from a lamp toward an area desired to be illuminated, the lamp being elongated along a longitudinal axis, said light diffuser comprising:a curved member that is positioned between the lamp and the area desired to be illuminated, the curved member being generally parallel to the longitudinal axis and symmetric about a plane that extends through the longitudinal axis, the curved member including:a first curved portion on one side of said plane of symmetry, said first curved portion extending from a first end, disposed adjacent the plane of symmetry and spaced from the lamp, to a second end, disposed adjacent the lamp and spaced from the plane of symmetry, anda second curved portion on an opposite side of said plane of symmetry, said second curved portion extending from a first end of the second curved portion to a second end of the second curved portion disposed adjacent the lamp and spaced from the plane of symmetry, the first end of the second curved portion being disposed adjacent the plane of symmetry and adjacent the first end of the first curved portion, wherein at least one of said first curved portion and said second curved portion defines a convex face oriented towards the lamp.
