  • Light-emitting device and vehicle lamp module
    Patent number: 11787332
    Abstract: A light-emitting device includes a substrate including circuit pads and a resin portion. A frame disposed on the substrate to form a first space, first to third light sources, and first and second encapsulants. The frame includes an outer wall and a first partition in the first space to form the first space as independent second and third spaces. A first and second light sources are disposed at the second space and provide first and second light beams respectively. A third light source is disposed at the third space and provides a third light beam. A first encapsulant is filled at the second space to seal the first and second light sources. A second encapsulant is filled at the third space to seal the third light source. The second encapsulant includes a first wavelength conversion material converting the third light beam into a fourth light beam.
