摘要: A white LED includes an chip formed on one main surface of a sapphire substrate, the being in semiconductor stack structure including light emitting layer and predetermined wavelength, extracting film applied other material having refractive index within range ±5% substrate that is located opposite side to processed into recess projection shape, phosphor member provided with respect film, generating as incident thereon.
