Patent ID: 8680545

Claim:
A light emitting device comprising: a package body comprising a cavity, the cavity having a bottom surface and four inclined sidewalls, the cavity having a depth of 450 μm or less in the package body; and a light emitting element in the cavity, wherein the four inclined sidewalls include a first inclined sidewall slanted with reference to the bottom surface, a second inclined sidewall slanted with reference to the bottom surface and facing the first inclined sidewall, a third inclined sidewall slanted with reference to the bottom surface, and a fourth inclined sidewall slanted with reference to the bottom surface and facing the third inclined sidewall, wherein, along the bottom surface of the cavity, a distance between the first inclined sidewall and the second inclined sidewall is different from a distance between the third inclined sidewall and the fourth inclined sidewall, and wherein an angle between the first inclined sidewall and a first imaginary plane perpendicular to the bottom surface of the cavity, an angle between the second inclined sidewall and the first imaginary plane perpendicular to the bottom surface of the cavity, an angle between the third inclined sidewall and a second imaginary plane perpendicular to the bottom surface of the cavity, and an angle between the fourth inclined sidewall and the second imaginary plane perpendicular to the bottom surface of the cavity are all different from each other.
