A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.

Light source module and vehicle lamp, having wavelength conversion member disposed in optical paths of first and second light-emitting elements

A light emitting device includes a light emitting element whose upper surface is a light extraction surface, and a light-transmissive member that has an upper surface and a lower surface, and covers the light extraction surface of the light emitting element. The light-transmissive member contains a phosphor. The upper surface and the lower surface of the light-transmissive member are both flat surfaces and parallel to each other. A side surface of the light-transmissive member has a protruding portion that protrudes to the side and has contact with the lower surface.

Light emitting device

There are provided a light emitting module including a luminescent material layer () which is disposed so as to cover a light emitting surface () of a semiconductor light emitting element () and which changes a wavelength of at least part of light emitted from the semiconductor light emitting element, and a light shielding wall () which surrounds the semiconductor light emitting element and the luminescent material layer from the circumference thereof, and the luminescent material layer is bonded to the semiconductor light emitting element and the light shielding wall with a bonding resin () having a light transmittivity, a distal end portion of the light shielding wall is caused to project further forwards than the luminescent material layer, and a transparent resin () is applied so as to cover an exposed surface () of a distal end portion () of the light shielding wall.
