Aligned multiple emitter package
First Claim
1. An emitter package, comprising:
- a casing comprising a cavity extending into the interior of said casing from a top surface of said casing; and
a lead frame integral to said casing, said lead frame comprising a plurality of electrically conductive carrier parts each holding at least one of a plurality of light emitting devices, said light emitting devices arranged in linear alignment and emitting out said cavity, said lead frame also allowing for an electrical signal to be applied to said light emitting devices through said lead frame, wherein said lead frame further comprises through-holes and V-cuts, wherein said V-cuts are disposed into said lead frame on planes running generally perpendicular to the surface of said lead frame, wherein at least some of said through-holes intersect with at least some of said V-cuts, said holes and cuts fitting with said casing;
wherein each of said carrier parts further comprises an integral thermally conductive body extending at least partially through to the bottom of said casing.

Abstract
A multiple element emitter package is disclosed for increasing color fidelity and heat dissipation, improving current control, increasing rigidity of the package assembly. In one embodiment, the package comprises a surface-mount device a casing with a cavity extending into the interior of the casing from a first main surface is provided. A lead frame is at least partially encased by the casing, the lead frame comprising a plurality of electrically conductive parts carrying a linear array of light emitting devices (LEDs). Electrically conductive parts, separate from parts carrying the LEDs have a connection pad, wherein the LEDs are electrically coupled to a connection pad, such as by a wire bond. This lead frame arrangement allows for a respective electrical signal can be applied to each of the LEDs. The emitter package may be substantially waterproof, and an array of the emitter packages may be used in an LED display such as an indoor and/or outdoor LED screen.
