LIGHT EMITTING DEVICE HAVING PLURALITY OF LIGHT-CONVERTING MATERIAL LAYERS

摘要

PURPOSE: A light emitting device having multiple wavelength conversion material layers is provided to form a transparent molding part between a wavelength conversion material layer and a light emitting diode. CONSTITUTION: A light emitting diode(23) emits the light having first wave length. A transparent molding part(25) is formed on a substrate(20) and covers the light emitting diode. A lower part wavelength conversion material layer(27) is formed on the transparent molding part. An upper wavelength conversion material layer(29) is formed on the lower part wavelength conversion material layer. A reflective mirror(26) includes a dielectric layer(26a) having a low refractive index and a dielectric layer(26b) having a high refractive index.
