Abstract: A fire resistant recessed luminaire constructed of an outer steel enclosure having a cylindrical shape that is open at one end and provided with a closed base at the opposite end. The open end has a shoulder extending outward from a perimeter of the outer steel enclosure. A fire insulation layer is disposed within and against the outer steel enclosure so as to conform to an inner shape of the outer steel enclosure. An inner steel enclosure is disposed within the fire insulation layer so as to force the insulation layer against the closed base and inner side wall of the outer steel enclosure. A light diffuser has a reflector trim extending outward from a second perimeter about an open end disposed in the inner steel enclosure so as to rest against a rim extending outward from an open end of the inner steel enclosure.

Abstract: A linear light-emitting diode (LED)-based solid-state lamp comprising an LED driving circuit, LED arrays, at least one pair of electrical contacts, and a controller, is used to replace a fluorescent tube or a conventional LED tube lamp in an existing lamp fixture. The controller and the at least one pair of electrical contacts are configured to perform galvanic isolation between the controller and the LED driving circuit connecting with LED arrays. Thus an overall through-lamp electric shock current can be limited only from the controller, eliminating a substantial electric shock current flow through the LED driving circuit and subsequently the LED arrays. The scheme can effectively reduce a risk of electric shock and an internal fire hazard to users during relamping or maintenance.
