LED projection night light
An LED projection night light for night time or dark area use includes a plug-in wall outlet night light or direct current operated night light with projection features to project an image, message, data, logo, or time on a ceiling, walls, floor, or other desired surface. The LED night light incorporates optics-lens and Object with preferred focus calculation to create bigger image to shown on locations. The parts for make night light including but not limited as an optics-lens, slides, openings, or cut-outs, and/or a transparent material piece, translucent material piece, telescope assembly, housing-member, slide-film, slide-disc, elastic-member, tilt-means, rotating-means, adjust-means, roller-means, mechanical-means, extend-means, convex lens, and/or concave lens designed to make the desired image, message, data, logo, or time project to the ceiling, walls, floor, or other desired surface to be seen by a viewer. The LED light upgrade model has an interchangeable power source arrangement, permitting the night light to be selectively powered by either an AC powered sealed-unit or a DC powered battery-pack.
1. An LED projection light, comprising:
more than one LED arranged to emit visible light beams to an image forming element positioned in front of the more than one LED,
wherein:
said LED projection light is powered by an AC power source via an external or built-in AC-to-DC circuit that provides DC power for the more than one LED and an integrated circuit (IC),
said image-forming element is one of a plurality of slides, films, lenses, or shaped holes included in a disc or holder or formed in one piece, and said disc, holder, or piece is fixed or movable in front of the more than one LED to form a desired image, message, data, logo, or time when light beams from the more than one LED pass through the image-forming element,
said LED light further includes at least one projection lens or cover in front of the image-forming element to project said desired image, message, data, logo, or time onto at least one of an indoor and outdoor surface that is feet away from and outside the LED projection light, said projection lens being installed (a) on a top area of an inner tube, inner tube assembly, or inner housing part, or (b) on an outer housing opening, and
light beams from the LED light are transmitted through said inner tube, inner tube assembly, or inner housing part travel to and pass through the projection lens or cover for projection to the indoor or outdoor projection surface.
2. An LED projection light as claimed in claim 1 , wherein the disc or holder is rotatable.
3. An LED projection light as claimed in claim 2 , wherein said image forming element is changed by moving, rotating, or tilting device in response to (a) manual operation, (b) an elastic member, or (c) operation of a push button.
4. An LED projection light as claimed in claim 1 , wherein the LED projection light further includes (a) a tilt mechanism, (b) a rotating mechanism, (c) an adjustment mechanism, (d) a swivel mechanism, (e) a moving mechanism, or (f) a bendable member, for changing and/or adjusting an angle, location, and orientation of the projected image, message, data, logo, or time.
5. An LED projection light as claimed in claim 1 , further comprising a mechanism for changing a relative position of said at least one image forming element, said more than one LED, and the projection lens to adjust a focus of said image.
6. An LED projection light, comprising:
at least one LED arranged to emit visible light beams;
at least one power source;
a built-in or external AC-to-DC circuit and/or a DC-to-DC circuit, connected to said at least one power source and to circuitry to cause said at least one LED to exhibit a desired light function, timing, color, brightness, and illumination effect;
an image-forming element positioned in front of the at least one LED to form a desired image, message, data, logo, or time when light beams from the at least one LED pass through the image-forming element,
said LED projection light further includes at least one projection lens in front of the image-forming element to enlarge and project said desired image, message, data, logo, or time onto a surface at least feet away and outside the LED projection light,
said LED projection light further includes a telescope, inner housing, or inner tube assembly to arrange the at least one LED, image-forming element, and projection lens,
wherein:
said LED projection light is supplied with power from at least one of an AC to DC adaptor, transformer, inverter, and DC power source.
7. An LED projection light as claimed in claim 6 , wherein the at least one image forming element includes a plurality of slides, film, lenses, or shaped holes mounted in a rotatable disc or holder.
8. An LED projection light as claimed in claim 6 , further comprising a mechanism for enabling a user to change said image, message, data, logo, or time by at least one of a roller or an elastic member.
9. An LED projection light as claimed in claim 6 , wherein said at least one image-forming element is changed by moving a roller using an elastic member or in response to pushing of a button.
10. An LED projection light as claimed in claim 6 , further comprising an extend and retract mechanism for changing a relative position of said at least one image forming element, said more than one LED, and a projection lens to adjust a focus of said image.
11. An LED projection light, comprising:
at least one LED arranged to emit visible light beams; and
at least one power source and circuitry connected to said at least one LED to cause said at least one LED to exhibit a desired light function, timing, color, brightness, and illumination effect:
wherein:
said LED projection light is arranged to be connected to at least one of (a) an electrical outlet, (b) an AC to DC adaptor, transformer, or inverter, and (c) a battery or electricity storage device;
said LED projection light includes an image-forming element in front of the at least one LED to form a desired image, message, data, logo, or time when light beams from the at least one LED pass through the image-forming element or transparent lens,
said LED projection light further includes a magnifying optics-lens in front of the image-forming element to enlarge and project said desired image, message, data, logo, or time onto a surface outside the LED projection light,
said LED projection light further includes a telescope, inner housing part, or tube to prevent leakage of light passing from the at least one LED to the image-forming element to the magnifying optics-lens, and
