Abstract
An image projector display device projecting an image onto a surface substantially parallel to a path of light emitted through a representation of an image and a projection/objective lens. The display device compensates for the varying distances of the surface onto to which the image is projected from the projection/objective lens to display a clear, non-distorted image.
Claims19
A light projector device for displaying an image on a surface, comprising:
- a mounting configured to be located proximate to the surface;
- a light emitting diode arranged on said mounting;
- an image representation disposed in a path of light emitted from said light source, wherein said image representation is a distorted representation of the image;
- and
- an objective lens disposed proximate said image representation to project an image projection onto a surface substantially parallel to the path of light emitted from said light source through said image representation and said objective lens,
- wherein the image projection is substantially similar to the image.

light projector device for displaying an image on a surface, comprising:
- means for emitting light;
- means for mounting said light emitting means proximate the surface;
- means for representing the image disposed in a path of light emitted from said light emitting means;
- means for concentrating light projected from said light projecting means towards said image representation means and
- a means for projecting the image disposed proximate said image representation means to project an image projection onto a surface substantially parallel to the path of light emitted from said light emitting means through said image representation means and said image projecting means,
- wherein the image projection is substantially similar to the image.

A night light for displaying an image on a surface, comprising:
- a mounting configured to be located proximate to the surface;
- a light emitting diode (LED);
- a representation of the image disposed in a path of light emitted from said LED;
- and
- a reflection mirror reflecting light from said LED toward said representation of the image;
- a concentration lens that concentrates light from said LED onto said representation of the image;
- a condensing lens disposed between said LED and said representation of the image;
- and
- an objective lens disposed proximate said representation of the image to project a projected image onto a surface substantially parallel to the path of light emitted from said LED through said representation of the image and said objective lens;
- and an orientation lens that orients an angle of light incident to the objective lens,
- wherein the projected is substantially similar to the image.
