LIGHT-EMITTING DEVICE, LIGHT MIXING DEVICE AND MANUFACTURING METHODS THEREOF |
摘要 |
Disclosed is a light-emitting device comprising: a carrier; a light-emitting element disposed on the carrier; a first light guide layer covering the light-emitting element, and disposed on the carrier; a wavelength conversion and light guide layer covering the first light guide layer and the light-emitting element, and disposed on the carrier; and a low refractive index layer disposed between the first light guide layer and the wavelength conversion and light guide layer; wherein the first light guide layer comprises a gradient refractive index, the wavelength conversion and light guide layer comprises a dome shape structure and is used to convert a wavelength of light emitted from the light-emitting element and transmit light, and the low refractive index layer is used to reflect light from the wavelength conversion and light guide layer. |
