Slit lighting effect

The light of the slits and the slit width and interval were decided based on the design, but as for the volume and directivity of the slits, since overlapping slits are not possible with one light, we used two lights with some space between them to create volume. The key point is that by using a filament clear LED lamp (lamp used: LDA5L/C/W) instead of a typical commercially available LED incandescent lamp, a stronger shadow effect was achieved.
