Title:
波長変換部材、プロジェクタおよび照明装置
Document Type and Number:
Japanese Patent JP6754946
Kind Code:
B2
Abstract:
The utility model provides a difficult emergence because wavelength converting part, projecting apparatus and lighting device that the metallic reflective layer's that the migration caused reflectionefficiency reduces. Wavelength converting part (10) are formed with metallic reflective layer (13) in proper order, increase reflection stratum (14) on base plate (11), fluorophor layer (15) and anti-reflection layer (16). It forms the whole in the region that is formed with metallic reflective layer (13) to increase reflection stratum (14) to have low -index layer (14a) and high refractive indexlayer (14b) in proper order from base plate (11) side. Fluorophor layer (15) form in the region that is formed with metallic reflective layer (13) some. Anti -reflection layer (16) form the whole inthe region that is formed with metallic reflective layer (13) to have first low -index layer (16a), high refractive index layer (16b) and second low -index layer (16c) in proper order from base plate(11) side.
