PLCC Package With A Reflector Cup Surrounded By An Encapsulant
First Claim
1. A PLCC package comprising:
- a first lead frame comprising;
a reflector cup;
a first tongue;
a second tongue; and
at least two leads;
a second lead frame comprising;
at least two leads;
a plastic structural body;
a light source;
an encapsulant;
an optical lens;
wherein the first and the second lead frames are attached to the plastic structural body;
wherein the light source is physically attached at the bottom of the inside of the reflector cup;
wherein the light source is electrically connected to the reflector cup;
wherein the light source is electrically connected to the second lead frame by a wire bond;
wherein at least four sides of the reflector cup are surrounded by the encapsulant, the encapsulant having a domed portion that functions as the optical lens, the encapsulant being an integral single piece structure.

Abstract
In an embodiment, the invention provides a PLCC package comprising first and second lead frames, a plastic structural body, a light source, an encapsulant, and an optical lens. The first lead frame comprises two tongues and a reflector cup. The first and second lead frames are attached to the plastic structural body. The light source is mounted and electrically connected at the bottom of the inside of the reflector cup. The light source is also electrically connected to the second lead frame by a wire bond. The reflector cup is surrounded on at least four sides by the encapsulant, the encapsulant having a domed portion that functions as the optical lens, the encapsulant being an integral single piece structure.
