Patent ID: 7501657

Claim:
A semiconductor light emitting device comprising: a light emitting element having a semiconductor multilayer structure that includes a light emission layer and is substantially in a shape of a regular hexagonal prism with a substantially regular hexagonal cross section; and a phosphor that is substantially in a shape of a cylinder and disposed to cover a main surface and lateral surfaces of the light emitting element, wherein the light emitting element has such a size that the substantially regular hexagonal cross section measures 2.8 mm or less in a longest diagonal, and d 2 /d 1 ≦1.4 is satisfied, where d 1 denotes a corner thickness of the phosphor that is measured from a corner of the substantially regular hexagonal prism along a line connecting the corner and a center of the substantially regular hexagonal cross section, and d 2 denotes a lateral thickness of the phosphor that is a largest thickness measured from a point on a side of the substantially regular hexagonal prism along a perpendicular bisector of the side.
