Abstract: A ceiling fan upper light includes a light casing. The light casing has at least one side wall made of a light-pervious material. At least one shielding plate made of an opaque material is annularly disposed inside the light casing. At least one groove is annularly disposed inside the light casing. The at least one groove is located between the at least one side wall and the at least one shielding plate. A plurality of light-emitting diodes is annularly disposed inside the light casing. The light-emitting diodes are located in the at least one groove. The light-emitting diodes do not extend out of the at least one groove. The light-emitting diodes emit light toward the opening of the groove, so as to prevent the light from directly irradiating the outside of the at least one side wall, so that the at least one side wall displays the light color of the light-emitting diodes.

Abstract: The blades of a ceiling fan are respectively provided with a top surface, a bottom surface and a wind-confronting portion obliquely formed along an edge of the top surface and the bottom surface. The wind-confronting portion is composed of two slopes respectively tapered symmetrically from the top surface and the bottom surface to an outmost tip of the blades. No matter if the top surface or the bottom surface faces downward after having the blades fixed with a shaft of a motor, the are a of the wind-confronting portion confronting air is always such minimized that air drag can be lowered. Moreover, with the top surface and the bottom surface attached with different patterns, various pattern combinations can be obtained to diversify the outlook of the ceiling fan.

Abstract: The blades of a ceiling fan are respectively provided with a top surface, a bottom surface, a front wind-confronting portion and a rear wind-confronting portion respectively formed along an edge of two sides of the top surface and the bottom surface. The front wind-confronting portion and the rear wind-confronting portion wind-confronting portion are respectively formed of a slope having the same inclined direction. No matter if the top surface or the bottom surface faces downward after having the blades fixed with a shaft of a motor, the area of the front wind-confronting portion or the rear wind-confronting portion confronting air is always such minimized that air drag can be lowered. Moreover, with the top surface and the bottom surface attached with different patterns, various pattern combinations can be obtained to diversify the outlook of the ceiling fan.
