Meanings: 大辞泉, スーパー大辞林 (electronic)

I wasn't able to find the general meaning corresponding to the original gloss "shade" (=shadow, darkness) in a dictionary, so the more specific meanings found in the electronic editions of 大辞泉, スーパー大辞林 seem more appropriate. The variant "セード"  is often used by lighting manufacturers, e.g. https://takizumi-denki.com/publics/search/?search_word=セード https://www.edrdg.org/~jwb/cgi-bin/ngramlookup?sent=照明セード+照明シェード+照明シェイド It's also more common overall than シェイド: https://www.edrdg.org/~jwb/cgi-bin/ngramlookup?sent=シェード+セード+シェイド
