  • Publication number: 20120257418
    Abstract: Embodiments of the invention are directed to a projection night light for illuminating a user-selected area of a room with an aesthetic or decorative pattern of light. In particular, there is provided a projection night light, which includes a body shell, and a spherical turning unit operatively coupled to the body shell. The spherical turning unit includes a cavity and a slide having a pattern thereon. The projection night light further includes a light source arranged in the cavity of the spherical turning unit. The light source is configured to pass light through the pattern on the slide forming a patterned light. The spherical turning unit is configured to project and direct the patterned light into a user-selected area of a room.
