Abstract
Lit image projection lamp and assemblies and methods to use the same to generate three-dimensional images. In an exemplary embodiment of a projection device of the present disclosure, the projection device comprises a light source and a curved lens positioned at a first distance from the light source, wherein the curved lens is a lenticular lens, having a concave portion and a convex portion, and wherein the projection device is configured to generate a homogenous light bar image from light emitted from the light source that passes through the curved lens.
Claims13
A projection device, comprising:
- a light source;
- an opaque mask having one or more custom apertures defined therethrough, each of the one or more custom apertures having a size and a shape;
- at least one first lens element and at least one second lens element;
- and
- a lenticular lens/sheet;
- wherein the projection device is configured to generate one or more three dimensional images corresponding to the one or more custom apertures of the opaque mask by emitting light from the light source and through the one or more custom apertures of the opaque mask, the at least one first lens element, the at least one second lens element, and the lenticular lens/sheet.
A projection device, comprising:
- a light source;
- a first lenticular lens/sheet;
- a second lenticular lens/sheet positioned distal to the first lenticular lens/sheet relative to the light source, the second lenticular lens/sheet having a negative image mask thereon or defined therein, the negative image mask having one or more opaque portions defining one or more open portions;
- and
- a third lenticular lens/sheet positioned distal to the second lenticular lens/sheet;
- wherein the projection device is configured to generate one or more three dimensional images corresponding to the one or more open portions of the negative image mask by emitting light from the light source and through the first lenticular lens/sheet, the negative image mask of the second lenticular lens/sheet, and the third lenticular lens/sheet.
