How do I light up bookshelfs? What type of lamp and settings should I use to achieve any of these (link 1, link 2, link 3, link 4) effects on my bookshelfs?

I only have sky texture and a sun in my scene and no ceiling.
Simply make the shelf and add a stripes of "light" to every part U wanna have lit. As U could see on the picture below (top-right corner) the lights are only a polygons with an emission material applied - that could be seen on the right. Set the power of light as U need and done!



Hope it helps my buddy, Jan.
