Abstract
Official abstract text for this publication.
A surface light source apparatus includes an end face for taking in light emitted from a light source and a main surface for emitting the light. The surface light source apparatus further includes a plurality of structure bodies formed on an opposed surface disposed opposite to the main surface in the surface light source apparatus, each of which has a reflecting surface facing the point light source. Each structure body has a cut-off portion which removes a portion on the reflecting surface in a longitudinal direction of the structure body and in a height direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A surface light source apparatus comprising: a point light source which emits light; an end face which takes in light emitted from the point light source; a main surface which emits the light; an opposed surface disposed opposite to the main surface; and a plurality of structure bodies having reflecting surfaces formed on the opposed surface, the reflecting surfaces facing the point light source, wherein each structure body has a cut-off port…
