Abstract:
1. A semiconductor light emitting apparatus having an optical axis extending in a light emitting direction comprising: a housing having an inner space; a semiconductor light emitting device located in the inner space of the housing; and a resin portion located in the inner space of the housing, wherein the inner space of the housing includes a first recessed portion having a bottom surface and a second recessed portion having an opening, the semiconductor light emitting device being located adjacent to the bottom surface of the first recessed portion, the second recessed portion being continuously formed above the first recessed portion such that the first recessed portion is located between the semiconductor light emitting device and the second recessed portion, wherein an upper portion of the first recessed portion and a lower portion of the second recessed portion forms a boundary portion, and the second recessed portion is larger in width than a width of the first recessed portion to form a stepped area at the boundary portion, wherein the resin portion includes a first resin and a second resin, the first resin being formed of a transparent resin material mixed with a wavelength converting material, the first resin located in the first recessed portion and configured to seal the semiconductor light emitting device, the second resin being formed of a transparent resin material and located above the first resin such that the first resin is located between the semiconductor light emitting device and the second resin, wherein the first resin is configured such that the first resin extends from an inner surface of the first recessed portion up to an inner surface of the second recessed portion to substantially cover the inner surface of the second recessed portion, and the first resin is recessed at its center area toward the semiconductor light emitting device to form a curved upper surface; and wherein the second resin is not in contact with both the inner surface of the first recessed portion and the inner surface of the second recessed portion, wherein the first resin has a lowermost level of the curved upper surface positioned nearer the semiconductor light emitting device than a lowermost level of the stepped area, such that an imaginary plane that is perpendicular to the optical axis and that intersects at least a point on the lowermost level of the curved upper surface located closest to the semiconductor light emitting device in the light emitting direction is closer to the semiconductor light emitting device than a second imaginary plane that is perpendicular to the optical axis and that intersects at least a point of the lowermost level of the stepped area located closest to the semiconductor light emitting device in the light emitting direction; and wherein the second resin has a curved lower surface, and the curved upper surface of the first resin and the curved lower surface of the second resin are matched to each other.
