  • Patent number: 6113433
    Abstract: An universal electrical lamp socket adapter for connecting multiple light bulbs to a single electrical socket. The universal electrical lamp socket adapter includes a central section and an adapter extending from an underside of the adapter for mating with the electrical socket. A first device for receiving an Edison type light bulb therein is positioned on the central section and a second device for receiving a Bayonet type light bulb therein is also positioned on the central section. The adapter and both the first and second receiving devices are electrically connected through the central section. When the adapter is coupled to a socket and at least one of an Edison type bulb is received within the first receiving device and a bayonet type light bulb is received within the second receiving device, power is provided to the at least one of the Edison type bulb and the Bayonet type light bulb allowing the at least one of the Edison type bulb and the Bayonet type light bulb to illuminate.
