Abstract

A lamp base having an electrical device recharging receptacle configured to receive a plug from a recharging device for a portable rechargeable electronic device. The receptacle is configured as a standard automobile cigarette lighter receptacle. The receptacle includes standard cigarette lighter receptacle electrical contacts that are connected to a voltage and current conversion circuit for receiving standard household voltage and converting it into standard automotive voltage and current.

Claims

1. A lamp base system for operating and recharging a portable electronic device comprising:

a lamp base;

a power source connected to the lamp base, wherein a standard household electrical current at standard household voltage is received into the lamp base;

a light fixture attachment on the lamp base, wherein an illumination element holding device is attached to the base to form the lamp;

a direct circuit for connecting the standard household electrical current and voltage to the light fixture;

an automotive cigarette lighter receptacle held in the lamp base for connection to an operating and recharging unit for a portable electronic device;

a conversion circuit connected between the power source and the automotive cigarette lighter receptacle, wherein the standard household electrical current and voltage from the power source is converted to a standard automotive voltage and current, wherein an operating and recharging unit that requires standard automobile electrical voltage and current may be plugged into the automotive cigarette lighter held in the lamp base for operating and recharging the portable electronic device;

an adapter receptacle, wherein the conversion circuit provides a voltage and current to the adapter receptacle;

a threaded USB adapter comprising a conversion circuit for converting the voltage and current provided to the adapter receptacle into a standard USB voltage and current and so that the threaded USB adapter may be unthreaded and replaced with an upgraded USB adapter having a different conversion circuit to convert the voltage and current provided to a different USB voltage and current.

2. A lamp base system for operating and recharging a portable electronic device comprising:

a lamp base;

a power source connected to the lamp base, wherein a standard household electrical current at standard household voltage is received into the lamp base;

a light fixture attachment on the lamp base, wherein an illumination element holding device is attached to the base to form the lamp;

a direct circuit for connecting the standard household electrical current and voltage to the light fixture;

an automotive cigarette lighter receptacle held in the lamp base for connection to an operating and recharging unit for a portable electronic device, wherein the automotive cigarette lighter receptacle comprises a plug receiving portion and a threaded portion;

a conversion circuit connected between the power source and the automotive cigarette lighter receptacle, wherein the standard household electrical current and voltage from the power source is converted to a standard automotive voltage and current, wherein an operating and recharging unit that requires standard automobile electrical voltage and current may be plugged into the automotive cigarette lighter held in the lamp base for operating and recharging the portable electronic device;

a USB adapter comprising a plug portion and a threaded portion so that the plug portion engages the plug receiving portion of the cigarette lighter receptacle when the threaded portion of the adapter engages the threaded portion of the cigarette lighter receptacle and having a USB conversion circuit for converting the voltage and current provided to the cigarette lighter receptacle into a standard USB voltage and current and so that the USB adapter may be unthreaded and replaced with an upgraded USB adapter having a different USB conversion circuit to convert the voltage and current provided to a different USB voltage and current.
