Abstract

An image projector display device (300) projecting an image onto a surface substantially parallel to a path of light emitted through a representation of an image (309) and a projection/objective lens (315). The display device compensates for the varying distances of the surface onto which the image is projected from the projection/objective lens to display a clear, non-distorted image.

Claims (21)

1. A light projector device for displaying an image on a wall, comprising:
a light source arranged in a housing configured for attachment adjacent to the wall;
an image representation disposed in a path of light emitted from said light source; and an objective lens disposed proximate said image representation to project an image projection onto a surface of the wall 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.
2. The device of claim 1, wherein a distance from said light source to a center of said objective lens is at a range of about 75 mm and about 225 mm.
3. The device of claim 1, further comprising a reflection mirror reflecting light emitted from said light source toward said image representation.
4. The device of claim 3, further comprising a planoconvex lens disposed between said light source and said image representation.
5. The device of claim 4, wherein said planoconvex lens is adjacent to said image representation.
6. The device of claim 4, further comprising a frensel lens disposed between said image representation and said objective lens.
7. The device of claim 6, wherein said light source is a light emitting diode.
8. The device of claim 6, wherein said image representation is a distorted representation of the image.
9. The device of claim 1, wherein said image representation is substantially similar to the image.
10. The device of claim 1, wherein the image projection is at least about 15 times greater in size than said image representation.
11. The device of claim 1, wherein said objective lens is arranged so that an angle between an axis of the path of light projected from a center of said objective lens and the surface of the wall is less than about 10 degrees.
12. A light projector device for displaying an image on a wall, comprising:
a means for emitting light arranged in a housing configured for attachment adjacent to the wall;
a means for representing the image disposed in a path of light emitted from said light emitting means; and a means for projecting the image disposed proximate said image representation means to project an image projection onto a surface of the wall 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.
13. The device of claim 12, wherein a distance from said light emitting means to a center of said image projecting means is at a range of about 75 mm and about 225 mm.
14. The device of claim 12, further comprising a means for projecting light from said light emitting means towards said image representation means.
15. The device of claim 14, further comprising a means for diffracting light to orient an angle of light incident to said image projecting means.
16. The device of claim 15, further comprising a means for concentrating light projected from said light projecting means towards said image representation means.
17. The device of claim 12, wherein the projected image is about 15 times greater in size than said image representation means.
18. The device of claim 12, wherein an angle between an axis of the path of light projected from a center of said objective lens and the surface of the wall is less than about 10 degrees.
19. A night light for displaying an image on a wall, comprising:
a light emitting diode (LED) arranged in a housing configured for attachment adjacent to the wall;
a representation of the image disposed in a path of light emitted from said LED;
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.
20. The night light of claim 19, further comprising:
a reflection mirror reflecting light from said LED toward said representation of the image; and a concentration lens that concentrates light from said LED onto said representation of the image.
21. The night light of claim 19, further comprising a condensing lens disposed between said LED and said representation of the image.
