光源モジュール、及びそれを備えた電子機器

Abstract

【課題】導光体の寸法公差及び組み立て公差を問わず、導光体のつなぎ目部分に発生する輝度ムラを低減し得る光源モジュール、及びそれを備えた電子機器を提供する。 【解決手段】光源モジュールの導光体21における長手方向に直交する断面の少なくとも一方の側端部は、導光体21における長手方向に直交する断面の中央部に形成されたT字厚肉部21cよりも薄く形成されたT字薄肉部21bとなっている。導光体21の最大厚さをT、隣接する導光体21・21のT字厚肉部21c・21c間の距離をL、導光体21のT字薄肉部21bにおける該導光体21の長手方向に直交する方向の長さをWとした場合、以下の関係式 Tan −1 (T/L)≦33.7°、かつ(1/3)≦(W/L)<(1/2) が成り立つ。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a light source module capable of alleviating brightness unevenness generated at knot parts of light guide bodies, irrespective of dimensional tolerance and assembly tolerance of the light guide bodies, as well as an electronic device equipped with the same.SOLUTION: At least one side end part of a cross section orthogonally crossing a length direction of each light guide body 21 of a light source module forms a T-shape thin part 21b formed thinner than a T-shape thick part 21c formed at a center part of a cross section orthogonally crossing a length direction of the light guide body 21. When a maximum thickness of the light guide body 21 is denoted by T, a distance between the T-shaped thick parts 21c, 21c of the adjacent light guide bodies 21, 21 is denoted by L, and a length in a direction orthogonally crossing the length direction of the light guide body 21 in the T-shape thin part 21b of the light guide body 21 is denoted by W, following relational expressions are satisfied: Tan(T/L)≤33.7°, and (1/3)≤(W/L)<(1/2).
