ABSTRACT:
A fan blade assembly for a ceiling fan has lightweight, oversized blades formed by a support frame with a blade covering material stretched over the frame. A lighting fixture attached to the support frame rotates with the fan blades. The fan blades are contoured to provide airfoil characteristics having an optimal compromise to maximize air circulation when rotating in a clockwise and counterclockwise direction. In a ceiling fan, the fan blade assembly can be used singluarly or used in combination with conventional fan blades on the ceiling fan.
