You can get aluminium extrusion on eBay that sets a LED strip at a 45 degree and comes with a diffuser...

If you mount that under the front edge of the shelf it looks a bit more professional than those plastic LED strip modules. Or you could mount upwards facing at the front.
You would need to use the LED strip lights that come in 5 metre rolls from eBay. They are very cheap and there are a bunch of remote control/dimming options...also cheap.
I always found that something like this would make for the best looking lighting display.
