Abstract
A light emitting module includes a light guide, a first light source, and a second light source. The light guide includes a first face, a second face oriented not parallel to the first face, a third face connected between the first face and the second face, and a light-emitting surface larger than each of the first face, the second face, and the third face. The first light source faces the first face. No light source is positioned between the first light source and an edge of the first face. The second light source faces the third face. No light source is positioned between the second light source and an edge of the third face. A distance from the second light source to the edge of the third face is greater than a distance from the first light source to the edge of the first face.
