Summary:An optical component (51) converts the wavelength of light (91) emitted from a light source (90). The optical component (51) has a first substrate (11) and a second substrate (21). The first substrate (11) includes a phosphor substrate (61). The second substrate (21) supports the first substrate (11). The second substrate (21) includes a translucent substrate (71) that receives, via the first substrate (11), the light (91) emitted from the light source (90). The translucent substrate (71) has a polycrystalline structure with orientation, thereby having crystal anisotropy in refractive index. Selon la présente invention, un composant optique (51) convertit la longueur d'onde de la lumière (91) émise à partir d'une source lumineuse (90). Le composant optique (51) possède un premier substrat (11) et un second substrat (21). Le premier substrat (11) inclut un substrat de phosphore (61). Le second substrat (21) porte ce premier substrat (11). Ledit second substrat (21) inclut un substrat translucide (71) qui reçoit, par l'intermédiaire du premier substrat (11), la lumière (91) émise à partir de la source lumineuse (90). Le substrat translucide (71) possède une structure polycristalline qui a une certaine orientation, ce qui permet d'obtenir une anisotropie cristalline dans un indice de réfraction. 光学部品(51)は、光源(90)からの光(91)の波長を変換するものである。光学部品(51)は第1基板(11)および第2基板(21)を有している。第1基板(11)は蛍光体基板(61)を含む。第2基板(21)は第1基板(11)を支持している。第2基板(21)は、光源(90)からの光(91)を第1基板(11)を介して受ける透光性基板(71)を含む。透光性基板(71)は、配向性をともなう多結晶構造を有することによって、屈折率の結晶異方性を有している。
