  • Patent number: 6809891
    Abstract: An image display device has a luminous image source operably positioned within a housing for projecting a projected image. The housing has a lens aperture covered by a lens assembly. The lens assembly is spaced apart from the luminous image source so that the lens assembly functions to projecting the luminous image outside of the internal chamber and beyond the lens assembly to appear as the image bubble that includes the projected image. The lens assembly includes a first lens, a second lens adjacent the first lens, and a third lens adjacent the second lens. The first lens has a first focal length that is approximately one-half of a focal length of the second or third lenses.
