LED Edge lit glass/acrylic panel

Hi does anybody here know the detail of how this needs to be constructed in real life.

What I want to achieve is to have a panle of glass with a name sandblasted on it. This panel will be buildt into a wall, so there needs to be a wai of getting to it, should any lights fail.

The effect should be that only the sandblasted part is lit up with the rest of the panel transparent.

Thanks
