Package structure for light emitting diode and applications of the same
First Claim
1. A light emitting diode (LED) package structure, comprising:
- a. at least three lenses, each lens having a body portion with at least a first surface, a second surface, a third surface, a fourth surface and a fifth surface that intersects with the first surface, the second surface and the fourth surface such that the fifth surface defines a concave portion in the body portion; and
b. at least three LED chips, each LED chip being capable of emitting light in a unique color and having a first conductive lead and a second conductive lead and embedded in the body portion of a corresponding lens such that the first conductive lead and the second conductive lead extend out of the body portion from one of the third surface and the fourth surface of the corresponding lens,wherein the at least three lenses and the at least three LED chips are assembled such that the first surface of one of the at least three lenses is substantially in contact with the second surface of one of the rest of the at least three lenses so that a concave is defined by the fifth surfaces of the at least three lenses and the at least three LED chips are positioned substantially proximate to each other and the at least three lenses form a shape of a sphere, a rectangle or a quadrate.

Abstract
A light emitting diode (LED) package structure. In one embodiment, the LED package structure includes at least three lenses, each lens having a body portion with at least a first surface, a second surface, a third surface and a fourth surface, and at least three LED chips, each LED chip being capable of emitting light in a unique color and having a first conductive lead and a second conductive lead and embedded in the body portion of a corresponding lens such that the first conductive lead and the second conductive lead extend out of the body portion from one of the third surface and the fourth surface of the corresponding lens. The at least three lenses and the at least three LED chips are assembled such that the first surface of a lens is in contact with the second surface of one of the rest of the at least three lenses and the at least three LED chips are positioned substantially proximate to each other.
