摘要:
A circuit includes a first source for providing an alternating electric field, a directional circuit connected to the first source for providing an alternating electric field by a transmission conductor there being no conductive return path provided back from the directional circuit to the first source for providing an alternating electric field. The directional circuit being a loop circuit which includes one or more circuit elements causing the loop circuit to be asymmetric to current flow; the directional circuit having no continuous connective path to earth ground, or battery ground, the directional circuit thereby developing a DC potential in response to the alternating electric field which is self referencing between a relatively high potential output and a relatively lower potential output. One or more loads connected to the directional circuit, the one or more loads also not having a continuous conductive path to earth ground or a battery ground. The load is not provided with a continuous connection to earth ground, or battery ground.

An AC LED package and circuits are disclosed along with an AC LED driver. The AC LED circuit may include as few as one LED or an array of anti-parallel LEDs driven with AC power sources and AC LED drivers at various voltages and frequencies. The AC LEDs are pre-packaged in various forms and materials and designed for mains or high frequency coupling in various forms to AC power sources, inverter type drivers or packages. The AC LED driver is a fixed frequency driver that provides a relatively constant voltage output to different size loads within the wattage limitation of the driver and in some cases is a direct mains power source.

摘要:
A telephone service provider or alarm company, supplies phone-line-power for auxiliary, backup, and/or emergency lighting in residential, commercial and/or industrial facilities at a reasonable charge in exchange for providing, maintaining and ensuring that lighting service and power will be available when needed such as under power failure situations. A phone-line-driven lighting device includes a sensor capable of detecting a primary power source. Once the sensor senses that the primary power source is not present, circuitry connects the device's phone line terminal to a light producing element, in turn powering the light producing element via a telephone line's DC or AC power. Such a device may include a control circuit which responds to a predetermined phone line signal, thereby controlling the operational state of the device. Such a signal could be broadcast in emergency or other informative situation by the provider of the phone line service.

摘要:
An LED lighting device comprising an integral body comprising a dielectric thermally conductive polymer has an electrically conductive material directly attached to, or at least in part is molded within the body and forms a circuit pattern. Two or more LED die each having at least a portion thereof being attached directly either to one of a portion of the first body for direct thermal conduction or a portion of the electrically conductive material for direct electrical and thermal conduction or both. The integral body is optionally molded to have integral cooling surfaces such as fins. The integral body also may take a shape conforming to a mounting structure of a lighting fixture and may also include thereon additional electrical components for assisting the LED die in producing light, in other words drive components. Terminals may be integrally molded or formed in the body upon which a portion of the conductive material resides for electrical connection to another device such as a power source.
