Abstract
A light emission package includes at least one solid state emitter, a leadframe, and a body structure encasing a portion of the leadframe. At least one aperture is defined in an electrical lead to define multiple electrical lead segments, with at least a portion of the aperture disposed outside an exterior side wall of the package. A recess may be defined in the exterior side wall to receive a bent portion of an electrical lead. A body structure cavity may be bounded by a floor, and side wall portions and end wall portions that are separated by transition wall portions including a curved or segmented upper edge, with different wall portions being disposed at different angles of inclination.

A light emission package adapted for use with at least one solid state emitter, the package comprising:
- a leadframe comprising a plurality of electrical leads;
- a body structure encasing at least a portion of the leadframe, the body structure comprising at least one exterior side wall;
- a heatsink retained by the body structure, and the heatsink being electrically isolated from each of the electrical leads;
- and
- wherein a first of the plurality of electrical leads comprises a plurality of first electrical lead segments extending through the at least one exterior side wall from a center portion of the body structure;
- and
- wherein each first electrical lead segment is separated from each other first electrical lead segment along the at least one exterior side wall by at least one first aperture, and at least a portion of the at least one aperture is disposed outside the at least one exterior wall.
A light emission package adapted for use with at least one solid state emitter, the package comprising:
- a leadframe comprising a plurality of electrical leads;
- a body structure encasing at least a portion of the leadframe, the body structure defining at least one exterior side wall;
- a heatsink retained by the body structure, and the heatsink being electrically isolated from the electrical leads;
- wherein at least a portion of a first electrical lead of the plurality of electrical leads extends through the at least one exterior side wall;
- and
- wherein the at least one exterior side wall defines at least one recess arranged to receive a bent portion of the first electrical lead.
