Title (EN) LIGHTING STRUCTURE
(FR) STRUCTURE D’ÉCLAIRAGE
(JA) 照明構造
Abstract:
(EN) The present invention mainly increases lighting efficiency. The present invention relates to a lighting structure comprising: a circuit substrate (6) having a light source (5) attached to the surface thereof; and a reflector (7) arranged so as to surround the light source (5) on the surface side of the circuit substrate (6). The reflector (7) comprises a pyramidal reflective wall section (15). The four inner walls of the pyramidal reflective wall section (15) are configured so as to obtain steeply inclined surface sections (33) having an angle (32) larger than 7.5° and smaller than 15° with respect to the direction of the optical axis (8) of the light source (5).
(FR) Selon l’invention, l’efficacité d’éclairage est augmentée. Plus précisément, l’invention concerne une structure d’éclairage qui possède : un substrat de circuit (6) à la surface duquel est installée une source lumineuse (5) ; et un réflecteur (7) qui est disposé côté surface de ce substrat de circuit (6), et de manière à entourer ladite source lumineuse (5). Ce réflecteur (7) possède une partie paroi de réflexion (15) en forme de cône carré. Les quatre faces de la partie paroi de réflexion (15) en forme de cône carré, constituent des parties en pente raide (33) dont l’angle (32) est supérieur à 7,5 degrés et inférieur à 15 degrés, avec la direction d’un axe lumineux (8) de la source lumineuse (5) pour référence.
(JA) 主に、照明効率を上げられるようにする。 表面に光源(5)が取付けられている回路基板(6)と、 この回路基板(6)の表面側に、上記光源(5)を取り囲むように設置されているリフレクター(7)とを有する照明構造に関する。 このリフレクター(7)が、方錐状の反射壁部(15)を有するものとされる。 この方錐状の反射壁部(15)の4つの内面が、光源(5)の光軸(8)の方向を基準として7.5度よりも大きく15度よりも小さい角度(32)の急斜面部(33)とされる。
