First claim

The invention claimed is:

1. An LED projection light, comprising:
at least one LED; and
a projection light housing having at least one added-on or built-in tubular piece,
where the added-on or built-in tubular piece has an inner space configured to fit just one said LED,
wherein LED light is emitted into the at least one added-on or built-in tubular piece and through an inner space of a fixed or rotating display unit containing at least one image or pattern, without emitting light to another inner housing or inner area that is insider the projection light housing and outside the at least one added-on or built-in tubular piece, the light exiting the display unit being emitted to a projection lens to project the at least one image or at least one pattern, or light beams, to a desired area or surface at least feet away from the projection light,
wherein the projection lens is fixed or arranged on a top area of (1) the LED projection light or (2) the at least one added-on or built-in tubular piece,
wherein the fixed or rotating display unit is made of a thin plastic piece that would melt if placed on top of a high temperature incandescent bulb,
wherein the fixed or replaceable display unit is at least one of a:
(i) film,
(ii) slide,
(iv) piece with photos, cartoons, or characters,
to create said image or lighted pattern,

wherein said added-on or built-in tubular piece is for preventing light leakage;
wherein a power source for said LED projection light includes at least one of:
(a) an AC power cord with a plug for connection to an AC power source for outdoor application,
(b) an external transformer or built-in AC-to-DC circuit for connection to an AC power source for outdoor application, and
(c) a DC power source that includes at least one battery, an external DC power source and separate USB wire, or an AC to DC conversion circuit for indoor application.

2. An LED projection light as claimed in claim 1 , wherein the LED projection light is one of a nighttime or seasonal, garden, or accent light.

3. An LED projection light as claimed in claim 1 , wherein the LED projection light has at least one of a motion sensor, photosensor, wired or wireless controller, and manual switch for operating the projection light.

4. An LED projection light as claimed in claim 1 , wherein the LED projection light has at least one built-in additional LED for at least one of night light, accent light, or background light illumination.

5. An LED projection light as claimed in claim 1 , wherein the LED projection light further has at least one movable part for changing at least one of an optics lens, a holder or disc, and a lens assembly.

6. An LED projection light as claimed in claim 1 , wherein said LED projection light is further incorporated with at least one of the following:
(1) a construction for changing a position of the projected image or pattern along x, y, and/or z coordinate axes;
(2) a mounting bracket, base, or sloped surface for changing or aiming the projected image or pattern at desired locations;
(3) additional kits for changing a position of an optics lens;
(4) a construction for rotating at least one housing part of the projection light;
(5) a construction for tilting the projection light;
(6) a construction for adjusting a focus of the projected image or pattern;
(7) a construction for changing, moving, or rotating the display unit;
(8) a construction for moving or changing or programming a digital image on an LCD or TFT of the projection light;
(9) a digital memory or data storage construction for storing a plurality of images;
(10) a construction including multiple projection assemblies for projecting a combination of steady, moving, and/or changeable multiple images or patterns from a single said LED projection light;
(11) a housing construction for housing at least one of an optical element, a lens assembly, a convex lens, a concave lens, display units, a slide, a film, an LCD display, a TFT display, an image presentation unit, and a transparent plastic piece that allows light to pass through and that includes a laser film or piece, a translucent piece, and an opaque plastic piece;
(12) a housing for housing a holder or disc for an forming element;
(13) a laser projection light integrated with at least one hologram or grating film or piece and including a safety component for shutting down the laser when a person is in proximity to the laser projection light;
(14) a wireless data display unit for displaying data received over a wireless data connection;
(15) a small size TFT having a size of 1, 1.5, 1.8, or 2.4 inches and a high resolution to provide a clear image when magnified by projection; and
(16) an OEL or OLED display screen.

7. An LED projection light as claimed in claim 1 , wherein the housing of the LED projection light has at least one slot for receiving a desired digital memory card, digital memory stick, or memory storage unit.

8. An LED projection light as claimed in claim 1 , wherein the LED projection light includes at least one of a digital memory storage kit, an integrated circuit (IC); a memory card; or a memory stick, for storing digital data or images to be projected by the LED projection light.

9. An LED projection light as claimed in claim 8 , wherein the display unit includes one of an LCD, TFT, and display construction, for displaying the digital data.

10. An LED projection light as claimed in claim 8 , wherein the LED projection light includes an adjustable focus kit to cause the projected image or pattern to have a desired size, density, clearance, sharpness, brightness, color, and distance.

11. An LED projection light as claimed in claim 8 , wherein said digital data is provided by one of a digital camera, video camera, computer equipment, communications equipment, an consumer electric device, and a cellular phone.

12. An LED desktop dome shaped projection light, comprising:
