Image projector display device
View Patent ↗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.
1. An image display device for displaying an image on a surface, comprising:
a housing configured to be located proximate to the surface;
a light source arranged on said housing;
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.
2. The image display 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 image display device of claim 1 , further comprising a reflection mirror reflecting light emitted from said light source toward said image representation.
4. The image display device of claim 3 , further comprising a planoconvex lens disposed between said light source and said image representation.
5. The image display device of claim 4 , wherein said planoconvex lens is adjacent to said image representation.
6. The image display device of claim 4 , further comprising a fresnel lens disposed between said image representation and said objective lens.
7. The image display device of claim 1 , wherein said image representation is substantially similar to the image.
8. The image display device of claim 1 , wherein the image projection is at least about 15 times greater in size than said image representation.
9. The image display device of claim 1 , wherein said objective 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 is less than about 10 degrees.
10. The image display device of claim 1 , wherein the surface is a wall, and wherein said housing attaches to the wall via an electrical outlet.
11. An image display device for displaying an image on a surface, comprising:
a light source for emitting light;
means for mounting said light source proximate the surface;
means for representing the image disposed in a path of light emitted from said light source;
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 source through said image representation means and said image projecting means,
wherein the image projection is substantially similar to the image
12. The image display device of claim 11 , wherein a distance from said light source to a center of said image projecting means is at a range of about 75 mm and about 225 mm.
13. The image display device of claim 12 , further comprising a means for projecting light from said light source towards said image representation means.
14. The image display device of claim 12 , wherein the projected image is about 15 times greater in size than said image representation means.
15. The image display device of claim 12 , wherein an angle between an axis of the path of light projected from a center of said image projecting means and the surface is less than about 10 degrees.
16. The image display device of claim 11 , wherein the surface is a wall, and wherein said means for mounting attaches to the wall via an electrical outlet.
17. A night light for displaying an image on a surface, comprising:
a housing configured to be located proximate to the surface;
a light source;
a representation of the image disposed in a path of light emitted from said light source; and
a reflection minor reflecting light from said light source toward said representation of the image;
a concentration lens that concentrates light from said light source onto said representation of the image;
a condensing lens disposed between said light source 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 light source 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.
18. The night light of claim 17 , wherein said surface is a wall, and wherein said housing attaches to the wall via an electrical outlet.
19. The night light of claim 17 , wherein an angle between an axis of the path of light projected from a center of said image projecting means and the surface is less than about 10 degrees.
20. The night light of claim 17 , wherein the light source is a light bulb or an LED.
