Light emitting module and automotive lamp
A light emitting module includes: a plurality of semiconductor light emitting elements; a substrate by which the arranged plurality of semiconductor light emitting elements are supported; and a plate-shaped light wavelength conversion component that is provided so as to face the light emitting surfaces of the plurality of semiconductor light emitting elements and that converts the wavelength of the light emitted by the semiconductor light emitting element. A phosphor layer has a shielding portion formed in the boundary between respective areas facing the respective light emitting surfaces of the adjacent semiconductor light emitting elements.
1. A light emitting module comprising:
a plurality of semiconductor light emitting elements;
a substrate by which the arranged plurality of semiconductor light emitting elements are supported; and
a plate-shaped fluorescent ceramic that is provided so as to face the light emitting surfaces of the plurality of semiconductor light emitting elements and that converts the wavelength of the light emitted by the semiconductor light emitting element,
wherein the fluorescent ceramic has a shielding portion formed in the boundary between respective areas facing the respective light emitting surfaces of the adjacent semiconductor light emitting elements, and
wherein the shielding portion is provided at a position above a gap between two adjacent semiconductor light emitting elements and is spaced apart from the substrate.
2. The light emitting module according to claim 1 , wherein the shielding portion is structured by injecting a shielding material for preventing light from transmitting therethrough into a groove formed in the fluorescent ceramic.
