Abstract
Disclosed is a curved surface element (e.g., light bulb, ornament, light pipe, etc.) which has at least a portion thereof (inner or outer surface) covered with a holographic diffraction grating which was constructed to be essentially distortion free on said curved surface, whereby such diffraction grating diffracts light to emit color to the observer. The diffraction grating can take for form of a holographic optical element (HOE) attached to the curved surface or a diffractive holographic optical pattern (HOP) embossed into the curved surface.
Claims54
A curved surface element having at least a portion thereof covered with a holographic optical element (HOE) diffraction grating which was constructed so that is it essentially distortion free when applied on said curved surface, whereby such diffraction grating diffracts light to emit color to the observer.
A curved surface element having at least a portion embossed with a holographic optical pattern (HOP) which is constructed to be essentially distortion free on said curved surface, whereby such HOP diffracts light to emit color to the observer.
A curved surface decorative ornament having at least a portion of its outer curved surface retaining a holographic image which was constructed to be essentially distortion free thereon and a reference light source which illuminates the interior of said ornament, whereby such essentially distortion free holographic image is displayed to the observer by said reference light source.
An improved light bulb having a curved surface outer bulb and an inner light emitting filament, the improvement which comprises:
- said outer bulb being embossed with a diffractive holographic optical pattern (HOP) which was constructed to be essentially distortion free on said curved surface.
