Light emitting device and method for manufacturing light emitting device

A light emitting device, comprising:

• a molded body having metal leads and a plane surface for mounting a light-emitting element;
• and
• a lens having a central portion, an edge portion surrounding the central portion, and a base portion supporting the central portion and the edge portion, wherein the central portion has a dome-shaped top surface, the edge portion has an inner top surface and an outer top surface, the inner top surface of the edge portion connects with the dome-shaped top surface of the central portion to form a valley-shaped groove, the base portion is attached onto the molded body to form a sealed chamber to enclose the light-emitting element, and any angle formed by any plane tangent to the outer top surface of the edge portion and a central axis of the central portion is between 0-45°.

A light emitting device, comprising:

• a molded body having metal leads and a plane surface for mounting a light-emitting element;
• and
• a lens having a central portion, one or more middle portions surrounding the central portion, an edge portion surrounding the one or more middle portions, and a base portion supporting the central portion, the one or more middle portions, and the edge portion, wherein the central portion has a dome-shaped top surface, each middle portion has a upside-down “v” shaped top surface, the edge portion has an inner top surface and an outer top surface, the inner top surface of the edge portion connects with the top surface of the outer-most middle portion to form a valley-shaped groove, the base portion is attached onto the molded body to form a sealed chamber to enclose the light-emitting element, and any angle formed by any plane tangent to the outer top surface of the edge portion and a central axis of the central portion is between 0-45°.
