一段时间以来,我一直在使用1-1/2英寸的灯架。附表40 PVC管材及配件一个10英尺长的。管段足够做成图中所示的支架。为了让我的作品更清晰,我使用了一个300瓦或500瓦的石英卤素灯,并将其固定在一个带有开关的金属插座盒上。该盒子是连接到顶部的立场通过一种电气配件称为追逐乳头,并拧成1/2英寸的PVC套管。内管螺纹。巢在1-1/2英寸。PVC耦合。柱的底部有一个PVC三通配件,有自己的出口和电线。 A 3-in. long piece of PVC pipe below the tee completes the column portion of the stand. I glued all the joints in the column and the base, except for the intersection between the two. This makes it easier to break down the stand for transport. This light is equally useful for outdoor work, but if you plan to leave it outside you should use weatherproof boxes for the electrical fittings.
