Light emitting module and planar light source

A light emitting module comprising:

• a light guide member comprising:
• an emission region defined by a sectioning groove,
• a light source placement part located in the emission region,
• a first light adjusting hole, and
• a second light adjusting hole,
• wherein, in a schematic top view, the first light adjusting hole and the second light adjusting hole are located between the sectioning groove and the light source placement part;
• a light source disposed in the light source placement part;
• a first light transmissive member comprising a light transmissive resin material, the first light transmissive member being provided in the light source placement part so as to embed the light source;
• and
• a first light adjusting member disposed on the light guide member, the first light adjusting member being located in a region including an area immediately above the light source placement part;
• wherein:
• the light source comprises:
• a light emitting element having a first face, a second face located opposite to the first face, and a third face extending from the first face to the second face,
• a second light transmissive member covering the second face of the light emitting element and the third face of the light emitting element,
• a cover member including a light diffusing material, the cover member covering the first face of the light emitting element and a lower face of the second light transmissive member, and
• a second light adjusting member including a light reflecting material, the second light adjusting member being disposed on the second light transmissive member;
• and
• a refractive index of an inside of the second light adjusting hole is lower than a refractive index of the light guide member,
• in the schematic top view:
• a shape of the emission region is quadrilateral,
• the first light adjusting hole is not positioned on a first straight line connecting a center of the light source and a corner of the emission region, wherein light emitted from the light source is totally reflected by a lateral face of the first light adjusting hole, and
• the second light adjusting hole is positioned at a region with which the first straight line intersects, wherein light emitted from the light source is refracted in the second light adjusting hole.

• and
• in the schematic top view:
• the light adjusting hole is not positioned on a first straight line connecting (i) a center of the light source and (ii) a point in the sectioning groove that is farthest from the center of the light source,
• the light adjusting hole has a first lateral face located on a side closer to the light source and a second lateral face located on a side opposite the first lateral face,
• the first lateral face of the light adjusting hole has a first region, and
• a line normal to the first region is oblique to a second straight line connecting (i) the center of the light source and (ii) a point in the sectioning groove that is closest to the center of the light source.
