Abstract: In one embodiment, a light-emitting device having a light source die, a substantially transparent encapsulant surrounding the light source die, and a second substantially transparent encapsulant at least partially covering the first substantially transparent encapsulant is disclosed. The second substantially transparent encapsulant may expose a portion of the first substantially transparent encapsulant. The second substantially transparent encapsulant may be less tacky, and may be hardened as compared to the first substantially transparent encapsulant. The second substantially transparent encapsulant may comprise a plurality of encapsulant islands that are distanced away from one another. In another embodiment, the light-emitting device may comprise a third substantially transparent encapsulant covering a portion of the first substantially transparent encapsulant that is exposed by the second substantially transparent encapsulant.

Abstract: A light-emitting device having a plurality of leads, a body, a light source die, a dark layer, and a substantially transparent encapsulant is disclosed. The dark layer absorbs a substantial portion of ambient light. The light source die may be a top emitting die. The light-emitting devices may be suitable for applications such as a large scale electronic display where each pixel is represented by each light-emitting device. The dark layer may contribute towards high contrast ratio by absorbing substantial amount of ambient light falling thereon.

Abstract: A light source having a lead frame, a body, and a plurality of dies, each die having an LED thereon is disclosed. The body includes a top surface, a bottom surface and a plurality of side surfaces. The lead frame includes first, second, and third sections, the first section includes a die mounting area having a first protrusion that passes through the body and terminates in a pad on the bottom surface. The second and third sections each include a protrusion that is bent to form first and second leads that run along one of the side surfaces. Each die is bonded to the die mounting area such that a first contact is electrically connected to the die mounting area, and a second contact is connected to one of the second and third sections. The first protrusion of the first section provides improved heat transfer.
