Slit lighting effect

The light of the slits and the slit width and spacing were decided based on the design, but as overlapping slits were not possible with a single light, two lights were used to create volume by overlapping the slits with some space between them.The key point was that by using a filament clear LED lamp (lamp used: LDA5L/C/W) rather than a typical commercially available LED incandescent lamp, a stronger shading effect was achieved.
