A network apparatus architecture is disclosed that includes one or more isolation circuits to accommodate a predetermined isolation voltage. Each isolation circuit enables an independent DC voltage to be selected along a network signaling path to accommodate different DC voltages of network circuits along the network signaling path. For example, DC isolation may be provided between a physical interface and a network circuit via one or more capacitors, optoelectronic isolators, coupled magnetic devices, or semiconductor devices. A network circuit may be powered by a power supply that is isolated from the rest of the network apparatus. The one or more isolation circuits and network circuits may be included in a system-on-chip, or application-specific integrated circuit.

A luminaire (10) is disclosed with built-in surge protection. The luminaire comprises an electrically conductive structure including a carrier (11) carrying at least one active circuit component (15, 16) and a shielding element (13) at least partially covering the carrier inside a housing, a set of active conductors (17, 19) connected to the active circuit component for connecting the active circuit component to a mains supply including a neutral (N) and live (L) terminal, wherein one of said terminals is further connected to the shielding element by a connection (19′) bypassing the at least one active circuit. The housing comprises a cover (21) over the electrically conductive structure, wherein the shielding element defines a clearance (25) between the electrically conductive structure and the cover, said clearance comprising a pinch point (27) between the shielding element and the cover.
