Abstract
(EN)
The present invention comprises: a rod-form light conductor (2) that extends in the longitudinal direction, guides the light entering from an end surface, and emits linear light from a side surface; a light conductor holder (3) having a hole into which the end surface of the light conductor (2) is inserted and having an opening in a first flat surface on the side opposite the surface in which the end surface of the light conductor (2) is inserted, the opening optically communicating with the hole; a housing (4) for accommodating the light conductor (2) and the light conductor holder (3), and supporting the light conductor holder (3) so that the end surface of the light conductor (2) is exposed; a light source substrate (5) on which a light source element (5a) for emitting light to the end surface of the light conductor (2) is formed; and a substrate protective layer (6) having a second flat surface covering the light source substrate (5), the surface of the second flat surface being flat, and the substrate protective layer (6) being formed on the light source substrate (5) except at least in an area where the light source element is formed. At a position where the light emitted by the light source element (5a) enters the end surface of the light conductor (2) that is exposed from the opening, at least one of the light source substrate (5) and the second flat surface of the substrate protective layer (6) is pressed against the housing (4) or the first flat surface.

La présente invention comprend : un conducteur de lumière en forme de tige (2) qui s'étend dans la direction longitudinale, guide la lumière entrant à partir d'une surface d'extrémité, et émet une lumière linéaire à partir d'une surface latérale ; un support de conducteur de lumière (3) comprenant un trou dans lequel la surface d'extrémité du conducteur de lumière (2) est insérée et comprenant une ouverture dans une première surface plane sur le côté opposé à la surface dans laquelle la surface d'extrémité du conducteur de lumière (2) est insérée, l'ouverture communiquant optiquement avec le trou ; un boîtier (4) pour recevoir le conducteur de lumière (2) et le support de conducteur de lumière (3), et supporter le support de conducteur de lumière (3) de sorte que la surface d'extrémité du conducteur de lumière (2) soit exposée ; un substrat de source de lumière (5) sur lequel est formé un élément de source de lumière (5a) pour émettre de la lumière vers la surface d'extrémité du conducteur de lumière (2) ; et une couche de protection de substrat (6) comprenant une seconde surface plane recouvrant le substrat de source de lumière (5), la surface de la seconde surface plane étant plane, et la couche de protection de substrat (6) étant formée sur le substrat de source de lumière (5) à l'exception au moins dans une zone où l'élément de source de lumière est formé. Dans une position où la lumière émise par l'élément de source de lumière (5a) pénètre dans la surface d'extrémité du conducteur de lumière (2) qui est exposée depuis l'ouverture, au moins l'un du substrat de source de lumière (5) et de la seconde surface plane de la couche de protection de substrat (6) est pressé contre le boîtier (4) ou la première surface plane.
