Abstract
A light socket utilizing a photocell and three-way switch including a cylindrical housing having an upper end, a lower end, and a cylindrical side wall therebetween. The upper end is couplable with a power source. The lower end has a light receiving socket disposed therein. The light receiving socket is adapted for receiving a light bulb therein. A frustoconical shield is secured to the cylindrical housing. The shield has a narrow open upper end and a wide open lower end. The narrow open upper end is secured to the lower end of the cylindrical housing. The wide open lower end is dimensioned to prevent the light bulb from directing light upwardly toward the cylindrical housing. A light activated switch is disposed within the cylindrical side wall of the cylindrical housing. The light activated switch is in communication with the light receiving socket whereby detection of ambient light will allow the light receiving socket to power the light bulb positioned therein. A three-way switch is disposed within the cylindrical side wall of the cylindrical housing. The three-way switch is in communication with the light receiving socket and the light activated switch.
