Abstract: A heat sink for a luminaire includes a central portion having a top surface and a bottom surface. The bottom surface is adapted to receive a lighting arrangement. The heat sink further includes a plurality of arms configured to dissipate heat generated by the lighting arrangement. The plurality of arms extend radially outward from the central portion. Each one of the plurality of arms is substantially arcuate between a proximal end and a distal end.

Abstract: A printed fuse fabrication is provided. The printed fuse includes a low thermal conductivity ceramic substrate and a fusible element printed on the substrate. The fusible element printed on the substrate includes a series of portions of reduced printed thickness, defining weak spots for fusible operation of the fusible element, respectively separated by portions of increased printed thickness.

Abstract: A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes an elongated planar substrate, a plurality of fusible weak spots, and a conductor. The weak spots are formed on the substrate and are longitudinally spaced from one another on the substrate. The conductor is separately provided from the substrate and the weak spots. The conductor includes a solid elongated strip of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The solid elongated strip of metal includes coplanar connector sections that are mounted to respective ones of the weak spots and obliquely extending sections bent out of plane of the connector sections to extend above the substrate.
