電動天棚簾，sky-light blinds，主要是運用在天窗方面的電動遮陽系統，根據運行原理可分為卷軸式天棚簾、折疊式天棚簾、葉片翻轉式天棚簾等。
Sky light blinds are mainly electric sunshade systems used in skylights. According to the operation principle, they can be divided into roller type skylight blinds, folding skylight blinds, blade overturning skylight blinds, etc.
卷軸式、折疊式電動天棚簾一般選用透光率不同的紡織品遮陽，葉片翻轉式遮陽系統一般采用垂直片、百葉簾片，通過葉片翻轉控制陽光進入室內的比例，達到遮陽效果。
The roller type and folding electric ceiling curtains generally use textiles with different light transmittance for shading. The leaf overturning sunshade system generally uses vertical sheets and shutter sheets to control the proportion of sunlight entering the room through leaf overturning, so as to achieve the sunshade effect.
