    • A lampshade made of a sheet of aluminum which is shaped by photochemical etching to form a one piece blank having six trapezoidally shaped side wall panels connected to one another in sequence in side-by-side relationship by fold lines, a plurality of locking tabs extending out from the side wall panel at one end of the sequence, an auxiliary panel extending out from the side wall panel at the other end of the sequence, and a plurality of locking slots formed on the auxiliary panel for engagement by the locking tabs to hold together the side wall panels at the ends of the sequence so as to form the lampshade. The blank is further shaped to include a first reinforcing flap hingedly connected to the top edge of each side wall panel by a fold line, a second reinforcing flap hingedly connected to the bottom edge of each flap by a fold line and a third reinforcing flap hingedly connected to at least some of the first reinforcing flaps, also each by a fold line, and a holding tab extending out from at least some of the side panels and being bendable into a holder for a leg of a spider which may be used to mount the lampshade on a lamp.
    • 一种由铝板形成的灯罩,其通过光化学蚀刻成形,以形成具有六个梯形侧壁板的一片坯料,所述六边形板侧面板通过折叠线以并排的关系依次彼此连接;多个锁定片延伸 在序列的一端处从侧壁面板出来的辅助面板在序列的另一端从侧壁面板延伸出来,并且多个锁定槽形成在辅助面板上,用于通过锁定接片保持接合 将序列末端的侧壁板一起组合,形成灯罩。 坯件进一步成形为包括通过折叠线铰接地连接到每个侧壁板的顶部边缘的第一加强翼片,通过折叠线铰接地连接到每个翼片的底部边缘的第二加强翼片和第三加强翼片铰接 连接到至少一些第一加强翼片,每个还有折叠线,以及从至少一些侧板延伸出来并且可弯曲成用于可用于安装 灯罩上的灯罩。
