High brightness light emitting diode (LED) packages, systems and methods with improved resin filling and high adhesion
First Claim
1. A high brightness package for housing light emitters, the package comprising:
- a body;
a cavity disposed in the body, the cavity comprising a cavity floor and at least one cavity wall, wherein the cavity wall intersects the cavity floor at an intersection area of the body; and
at least one electrical element disposed in a portion of the body, wherein the at least one electrical element comprises a conductive surface, at least two external portions, and one or more transitional zones disposed between the conductive surface and the at least two external portions;
wherein the conductive surface forms a portion of the cavity floor for electrically connecting with one or more light emitters; and
wherein the at least two external portions of the electrical element extend about an aperture, wherein the one or more transitional zones are disposed at at least one edge defining the aperture and are recessed into the body below the cavity floor such that a gap forms between the one or more transitional zones and the intersection area, wherein the gap is filled by the body, and wherein a portion of the aperture is filled by the body.

Abstract
High-brightness light emitting diode (LED) packages, systems and methods with improved resin filling and high adhesion are provided. In one aspect, a high brightness package for a light emitter (e.g., a LED or LED chip) can include a body and a cavity disposed in the body. The cavity can include at least one cavity wall extending toward an intersection area of the body where the cavity wall intersects a cavity floor. The package can further include at least one electrical element having first and second surfaces, each of the first and second surfaces proximate the intersection area. The first surface can be disposed on a first plane and the second surface can be at least partially disposed on a second plane that is different than the first plane. The body can at least substantially cover the second surface.

17. A high brightness package for housing light emitters, the package comprising:
-
a body; a cavity disposed in the body, the cavity comprising a cavity floor and at least one cavity wall, wherein the cavity wall intersects the cavity floor at an intersection area of the body; and a leadframe disposed within a portion of the body, the leadframe comprising at least one electrical element; wherein the electrical element comprises one or more openings disposed therethrough, wherein each of the one or more openings are positioned below a portion of the intersection area, wherein at least one edge defining a respective one of the one or more openings in the at least one electrical element is disposed inboard of the intersection area such that a gap is disposed between the edge of the at least one electrical element and the intersection area such that an area disposed below the portion of the intersection area where the cavity wall intersects the cavity floor is devoid of the electrical element, and wherein the body at least partially fills the gap between the edge of the electrical element and the intersection area. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
