ABSTRACT:
A lamp socket adapter to receive a relatively low cost, low voltage (e.g., wedge base or bipin) light bulb so that the light bulb can be powered from a source of 12 volts AC or DC. The lamp socket adapter of this invention is adapted to be rotated into mating engagement with a standard Edison-type lamp socket that is to be connected to receive one of an AC or DC voltage. By virtue of the foregoing, an efficient light bulb circuit is available by which one or more low voltage light bulbs can provide bright light over an area to be illuminated with reduced power consumption relative to a conventional 120 volt AC-powered incandescent light bulb. The lamp socket adapter includes an upstanding bulb pedestal to which the light bulb is attached and supported. First and second electrically-conductive strips extend through the lamp socket adapter by which to connect the low voltage light bulb seated upon the bulb pedestal to the Edison lamp socket so that the light bulb can be powered by the 12 volts AC or DC supplied to the lamp socket.
