Abstract

A projection assembly is arranged to be added onto or built into at least one LED-unit or other light-unit of an illuminated object that has more than one LED or other light source to cause the object to be illuminated and show the object'"'"'s design or appearance while also offering illumination to people. The illuminated object may include all kinds of seasonal lighting, regular light fixtures, track lights, desktop lights, and battery operated lights having more than one light-unit or LED-unit.

Claims

1. A projection arrangement for a variety of LED lights, comprising:

at least one projection assembly including means for projecting an image onto a surface spaced from the projection assembly, said projection assembly including an optics lens;

a display for forming said image to be projected by the lens; and

a housing, wherein a light source for said projection assembly is provided by a light of a main object onto which the projection assembly is assembled, said light source emitting light beams that pass through said lens and said display to form said image on said surface spaced from said projection assembly,

wherein the display includes at least one of a slide, film, digital data, LCD screen, stencil, miniature piece, indicia, art work, design, and display of a message, words, slogan, advertisement, or cartoon character,

wherein said at least one projection assembly is arranged to be assembled to a main object,

wherein said at least one projection assembly is arranged to have a fixed or changeable projection angle with moving images, an automatically or selectively changeable image, or a single image, and

wherein said main object includes said light and circuitry for providing power to the light according to predetermined functions, said light selected from the group consisting of a light of a seasonal light string, seasonal desk top light, seasonal ornament, seasonal door decorative item, seasonal garden light, seasonal outdoor lighting, lighting fixture, track light, USB light, battery-operated light, seasonal tree top light, seasonal wall device light, and seasonal outdoor device.

2. A projection arrangement as claimed in claim 1, wherein the light of the main object serves as a light source for the projection assembly.

3. A projection arrangement as claimed in claim 2, wherein the light is an LED light.

4. A projection arrangement as claimed in claim 1, wherein the projection assembly further includes its own light source.

5. A projection arrangement as claimed in claim 4, wherein the light is an LED light.

6. A projection arrangement for a variety of LED lights, comprising:

at least one projection assembly for projecting an image onto a surface spaced from the projection assembly, said projection assembly including an optics lens;

a housing, wherein a light source for said projection assembly is provided by an external LED light onto which the projection assembly is assembled, said light source emitting light beams that pass through said lens and said display to form said image on said surface spaced from said projection assembly,

wherein the display includes at least one of a slide, film, digital data, LCD screen, stencil, miniature piece, indicia, art work, design, and display of a message, words, slogan, advertisement, or cartoon character,

wherein the projection arrangement further includes quick installation means for assembling the projection assembly to said LED light, and

wherein the projection assembly does not include its own light source, said light source for the projection assembly instead being provided by at least one LED of the LED light.

7. A projection arrangement for a variety of LED lights, comprising:

at least one projection assembly for projecting an image onto a surface spaced from the projection assembly, said projection assembly including an optics lens;

a display for forming said image to be projected by the lens; and

a housing, wherein a light source for said projection assembly is provided by an external light unit onto which the projection assembly is assembled, said light source emitting light beams that pass through said lens and said display to form said image on said surface spaced from said projection assembly,

wherein the display includes at least one of a slide, film, digital data, LCD screen, stencil, miniature piece, indicia, art work, design, and display of a message, words, slogan, advertisement, or cartoon character,

wherein said at least one projection assembly is arranged to have a fixed or changeable projection angle with moving images, an automatically or selectively changeable image, or a single image, and

wherein said external light unit is one of a plurality of light units of an LED light, said LED light being selected from the group consisting of a light of a seasonal light string, seasonal desk top light, seasonal ornament, seasonal door decorative item, seasonal garden light, seasonal outdoor lighting, lighting fixture, track light, USB light, battery-operated light, seasonal tree top light, seasonal wall device light, and seasonal outdoor device.

8. A projection arrangement for a variety of LED lights, comprising:

at least one projection assembly for projecting an image onto a surface spaced from the projection assembly, said projection assembly including an optics lens;

a display for forming said image to be projected by the lens; and

a housing, wherein a light source for said projection assembly is provided by an external LED light onto which the projection assembly is assembled, said light source emitting light beams that pass through said lens and said display to form said image on said surface spaced from said projection assembly,

wherein the display includes at least one of a slide, film, digital data, LCD screen, stencil, miniature piece, indicia, art work, design, and display of a message, words, slogan, advertisement, or cartoon character; and

attachment means for attaching the at least one projection assembly to said external LED light such that the LED serves as a light source for the projection assembly, and said attachment means further causing said projection means to have a desired orientation in order to project an image to a preferred location with a desired size and focus.
