Abstract

A unitary die-cast cap for a downlight can includes a base section and a plurality of heat-sink fins. The base section is a plate that includes an interior base-surface, an exterior base-surface, and an exterior wall-surface. The exterior base-surface, which is an opposite surface of the interior base-surface, forms an exterior top-surface of a downlight tubular can. The exterior wall-surface is configured to be positioned in direct attachment to an interior wall-surface of the downlight can. The plurality of heat-sink fins extend from the interior base-surface and form a substantially cylindrical exterior heat-sink wall touching or in close proximity to the interior wall-surface of the downlight can.
