Abstract:
(EN) The present invention addresses the problem of providing a technique for improving the heat dissipation properties of a light source. A surface light source device according to the present invention is provided with: a light source; a light guide plate that has a light entrance surface, on which the light emitted by the light source is incident, on a lateral side and discharges the light incident on the light entrance surface from a light exit surface; a wiring substrate; and a metal frame which comprises a bottom part having a bottom surface that faces a surface on the reverse side of the light exit surface, a lateral wall that stands on the outer periphery of the bottom surface, and a projection part that is provided on the lateral wall and protrudes toward the bottom surface, and which houses the light source, the light guide plate and the wiring substrate. At least a part of the light source is arranged between the bottom part and the projection part; and the wiring substrate is arranged between the light source and the bottom part.
(FR) Le problème décrit par la présente invention est d'obtenir une technique permettant d'améliorer les propriétés de dissipation de la chaleur d'une source lumineuse. Un dispositif de source lumineuse de surface selon la présente invention comprend : une source lumineuse ; une plaque de guidage de lumière qui a une surface d'entrée de lumière, sur laquelle la lumière émise par la source lumineuse est incidente, sur un côté latéral et qui décharge la lumière incidente sur la surface d'entrée de lumière à partir d'une surface de sortie de lumière ; un substrat de câblage ; et un cadre métallique qui comprend une partie inférieure ayant une surface inférieure faisant face à une surface sur le côté inverse de la surface de sortie de lumière, une paroi latérale se tient sur la périphérie externe de la surface inférieure et une partie de projection est disposée sur la paroi latérale et fait saillie vers la surface inférieure, et qui contient la source lumineuse, la plaque de guidage de lumière et le substrat de câblage. Au moins une partie de la source lumineuse est disposée entre la partie inférieure et la partie de projection. Le substrat de câblage est disposé entre la source lumineuse et la partie inférieure.
(JA) 光源の放熱性を向上する技術を提供することを課題とする。面光源装置は、光源と、光源が発する光が入射する入光面を側方に有し、入光面から入射する光を出光面から出射する導光板と、配線基板と、出光面の反対側の面に対向する底面を有する底部、底面の外周に立設された側壁、及び、側壁に設けられ、底面側に突出する突出部を有し、光源、導光板及び配線基板を収容する金属フレームと、を備え、光源の少なくとも一部分が、底部と突出部との間に配置され、配線基板が、光源と底部との間に配置されている。
