A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.

A technique for detecting defects in aircraft wiring, such as for detecting partial discharges or arcing in wiring or cables is disclosed. A high frequency current transformer (HFCT) is fixingly positioned in contact with a wire so that the wire is encircled by the HFCT. Partial discharges from a damaged wire so encircled will induce a current in the HFCT proportional to the current of the discharge. The HFCT includes a conductive coil-like pattern formed onto a flexible insulating material. The insulating material has slits between each coil-turn. The HFCT also includes a core of flexible material fitted between the coil-turns through the slits.

Current transformers for partial discharge detection on aircraft cables and wires

A cable, system and method for detecting partial discharges or arcing in wiring or cables via fiber optics are provided. The cable for detecting partial discharges includes a conductor for carrying electrical signals; at least one fluorescent optical fiber for detecting light generated by a partial discharge; and a first transparent layer surrounding the conductor for supporting the at least one fluorescent optical fiber generally parallel to the conductor. By employing a fluorescent optical fiber, incident light generated by a partial discharge along a length of the optical fiber will be transmitted via the optical fiber to an optical receiver for determining a partial discharge has occurred.

Detection of partial discharge or arcing in wiring via fiber optics

A system and method for detecting partial discharges or arcing in wiring or cables is disclosed. The system employs a high-voltage AC power source to generate a high-voltage low-current AC waveform, which is propagated through a selected wire, which in turn, produces the return signal. The return signal is processed using a signal processor and the analyzed for indications of the occurrence of a partial discharge. The method detects damage to a selected wire by utilizing high voltage, low current AC waveforms to induce partial discharges in a controlled manner and detecting a return signal resulting from the discharge.

Low current AC partial discharge diagnostic system for wiring diagnostics

A method and apparatus are described for a networked lighting system that may be controlled either remotely or locally by a power line communication (PLC) link. The components of the system, addressable lamp ballasts and addressable wall switches, replace their conventional counterparts. The resulting networked lighting system implemented with these components is controlled remotely from a centralized building control center. A particular room may be controlled by the building control center or locally by a wall switch. The invention requires no rewiring of the building's wiring plant, because the addressable components are direct electrical replacements, and installation of the system, therefore, takes a minimum amount of time.
