Abstract: The present invention relates to a sector of fan and its manufacturing method, including non-skeleton sector and skeleton sector. The non-skeleton sector of fan is molded by injecting polyurethane foam into a sector molding die; the skeleton sector of fan is comprised of a main body and a framework, wherein said main body and the framework are molded together in similar shape with solid casting resin or other similar material; said framework made of steel wire according the sector's shape and size is comprised of an outer shaped ring, reinforcing ribs and a core bar, if necessary inner shaped rings and crossing reinforcing ribs employed for enhancing the intensity of the sector, but it is always in grid structure. Said outer shaped ring, the reinforcing ribs and the core bar are fastened together, and then an assembling disk is fixed on the back end.

Abstract: The present invention relates to a lampshade and manufacturing method, including how to manufacture the framework components and how to combine them together; said framework components include upper ring, low ring, linking members, ring connectors, upper and low socket adaptors; wherein said upper and low rings are made of circular steel bar in butt welding, and the ring plugs are welded on the stem of ring in uniform distribution, which is made of punched steel sheet by die; said upper and low socket bases of the framework are molded with plastic in one time; said linking members of the framework are made of punched steel sheet, which is plugged into the upper and low plastic socket bases with the both ends respectively; the plastic socket bases are connected to the upper and low rings together via the ring plugs; the combined lampshade framework appears into small top and big bottom. Said framework structure has high strength, not easy damage, and good looking feathers.

Abstract: A lamp head with multiple luminous modes has a frame body. A lateral side of the frame body having a through hole. An inner wall of the through hole has a plurality of clamp seats. Each clamp seat has a positioning pin and an elastomer. Masks are installed on the positioning pin and are clamped by the clamp seat so as to be positioned in the frame body. Thereby, the assembly of the lamp head is formed. The masks are made of material with the same or different transparencies. Thereby, when the light is emitted, by the arrangement of the masks, the lamp present a luminous modes selected from same transparency at two sides different transparencies at two sides, and only one side being transparent.
