Abstract:
An apparatus for efficiently coupling light from a light source into a thin object such as a rod or a sheet is disclosed. In an embodiment, the apparatus comprises a sheet and a linear light source placed along the edge of the sheet. The light from linear light source is coupled into the sheet using one or more concentrator blocks. In another embodiment, the apparatus comprises a rod and a point light source placed near one end of the rod. The light from point light source is coupled into the rod using one or more concentrator blocks.
