LIGHT EMITTING DEVICE EMPLOYING DIELECTRIC MULTILAYER REFLECTING MIRROR

摘要

PURPOSE: A light emitting device using a dielectric multilayer reflecting mirror is provided to use a dielectric multilayer reflecting mirror, thereby preventing light from being lost due to a first light emitting diode because light emitted from a second light emitting diode is incident into a wavelength conversion material. CONSTITUTION: A first light emitting diode(21) emits light which has a first wavelength. A second light emitting diode(23) emits light which has a second wavelength. A wavelength conversion material(25) converts light of the first wavelength into light of a third wavelength. A reflective mirror layer(30) is formed on the wavelength conversion material. The reflective mirror layer reflects light of the second wavelength. A sealing resin(40) covers the wavelength conversion material and the second light emitting diode.
