Abstract
A light emitting diode contains a package structure and a light emitting diode die embedded in the package structure. The package structure has an elliptic bottom surface having a semi-major axes and a semi-minor axis and a semi-ellipsoidal surface connecting and surrounding the edge of the elliptic bottom surface, wherein the maximum height of the ellipsoidal surface from the elliptic bottom surface is between the semi-major axes and the semi-minor axis.
Claims13
A light emitting diode module, comprising:
- a package structure comprising:
- an elliptic bottom surface having a semi-major axis and a semi-minor axis;
- and
- a semi-ellipsoidal surface surrounding and connecting all the edges of the elliptic bottom surface, the largest vertical distance from the semi-ellipsoidal surface to the elliptic bottom surface being between the length of the semi-major axis and the length of the semi-minor axis;
- and a light emitting diode die embedded in the package structure.
