Abstract:
The light emitting device package of the present invention has a longitudinal direction (as viewed from above) and a transverse direction perpendicular to the longitudinal direction, and is provided with a first and second lead-frame lined-up in the longitudinal direction and molded resin holds the first and second lead-frames integrally. The package is characterized in that the first lead-frame has a main body and an extension that extends from the main body with a narrowed width towards the second lead-frame. Further, a recess is established in the bottom surface of the first lead-frame, and at least part of the exposed region of the bottom surface of the extension is separated from the exposed region of the bottom surface of the main body by the molded resin that fills the recess.

A planar light source includes: a support member including a wiring substrate, a light guide member, a light source disposed in a hole of the light guide member, and a first reinforcing member disposed on the support member and surrounding the light guide member in a plan view. The first reinforcing member includes first and second portions extending in a first direction and facing each other, and includes third and fourth portions extending in a second direction orthogonal to the first direction and facing each other. At least one of the first portion, the second portion, the third portion, and the fourth portion has light reflectivity to light emitted from the light source. In the plan view, the light guide member is located between the first and second portions in the second direction, and is located between the third and fourth portions in the first direction.

A planar light source includes a light guide member having a through hole, a light source, a first light adjusting member, a second light adjusting member, and a light transmissive member. The first light adjusting member having reflectivity and transmissivity with respect to light from the light source is disposed on or above an upper face of the light source in the through hole. The second light adjusting member having reflectivity and transmissivity with respect to the light from the light source is disposed above and apart from the first light adjusting member. The first light transmissive member having a higher transmissivity with respect to the light from the light source than the transmissivities of the first and second light adjusting members is disposed between the first light adjusting member and the second light adjusting member, and between a lateral face of the light source and the light guide member.

The base member defines a plurality of depressed portions separated from the via hole in a front view and opening on a back surface and a bottom surface of the base member. The substrate includes a third wiring covering at least one of inner walls of the plurality of depressed portions and electrically connected to the second wiring. A depth of each of the plurality of depressed portions defined from the back surface toward the front surface is larger on a bottom surface side than on an upper surface side of the base member.
