要約
(EN)
This light source apparatus is provided with: a light source; a diffusion member that diffuses light emitted from the light source; a reflection sheet that reflects the light to the diffusion member, said light having been emitted from the light source; a storing housing that houses the diffusion member and the reflection sheet such that the diffusion member and the reflection sheet face each other; and an aligning section, which is provided in the storing section, and which determines positions of the diffusion member and the reflection sheet in the storing housing. A protruding section is provided on one end portion of the reflection sheet, said protruding section being at a position corresponding to, in the facing direction, a diffusion member cutout corresponding to the aligning section, thereby increasing light reflectivity in the vicinity of the diffusion member cutout.

La présente invention se rapporte à un appareil de source de lumière qui comprend : une source de lumière ; un élément de diffusion qui diffuse la lumière émise depuis la source de lumière ; une feuille de réflexion qui réfléchit la lumière vers l'élément de diffusion, ladite lumière ayant été émise depuis la source de lumière ; un boîtier de stockage qui contient l'élément de diffusion et la feuille de réflexion de telle sorte que l'élément de diffusion et la feuille de réflexion soient orientés l'un vers l'autre ; et une section d'alignement qui est agencée dans la section de stockage et qui détermine les positions de l'élément de diffusion et de la feuille de réflexion dans le boîtier de stockage. Une section en saillie est agencée sur une partie d'extrémité de la feuille de réflexion, ladite section en saillie se trouvant à une position qui correspond, dans la direction d'orientation, à une échancrure de l'élément de diffusion correspondant à la section d'alignement, ce qui permet d'augmenter la réflexion de lumière à proximité de l'échancrure de l'élément de diffusion.
