Abstract

An LED light has a built-in projection light and a night light to offer at least two functions for people in a dark environment. The projection light can project an image from any type of display-unit irrespective of geometric shape or image source or type, including display of digital data, wireless digital data, an LCD or TFT screen display, or any other display, enabling images of enlarged size to be projected onto a preferred surface, making it easier for people to see the image. The built-in night light helps people see things in a dark environment.

Claims

1. An LED light, comprising:

an LED light housing with movable parts; and

at least one projection assembly in said LED light housing, said projection assembly including at least one LED and projection parts, the projection parts including;

a tubular assembly including a tube for preventing light leakage, the at least one LED being positioned such that narrow LED light beams enter a first end of the tube; and

an optical projection lens at a second end of the tube for transforming the narrow LED light beams into wider area light beams thereby magnify and project an image formed by an image forming element, said image being projected onto a surface at least an arm'"'"'s length away from said LED light,

wherein said image forming element includes at least one of the following image forming elements situated at least partially in said tubular assembly between the first end of the tube and the second end of the tube;

(a) a fixed image forming element including a fixed display unit or film;

(b) a changeable image forming element including a time piece screen, LCD display, a TFT display, an Lcos display, or a digital data display;

(c) a wireless transmitting and receiving changeable digital data element, including a wireless digital data display, a weather display, or a wireless display screen; and

(d) image-forming opaque, translucent, and transparent elements,

wherein said at least one projection assembly is arranged to project at least one of the following images;

time, weather information, messages, digital data, cartoon characters, advertisements, seasonal data, promotion art, graphics, and light beams only, and

wherein said LED of the projection assembly is arranged to be turned on and off to achieve predetermined functions, effects or performance in response to a switch, sensor, manual control or wireless control,

wherein the LED light is powered by one of;

(A) alternating current (AC) input through prongs plugged into an outlet and circuitry for converting the input AC into an LED circuit working current; and

(B) direct current (DC) from a battery, USB wired power source, USB backup power source, solar power source, wind power source, generator power source, transformer having a DC power output, an adaptor having a DC power output, and a DC power storage element,

wherein a position or orientation of the magnified image projected onto a desired surface is adjustable by applying a force to the movable parts of the said LED light housing.

2. The LED light of claim 1, wherein the housing, projection light LED, and projection light parts form a projection head that is arranged to swivel, rotate, or spin to change a position, orientation, or direction of the projection head.

3. The LED light of claim 1, wherein a focus of the projection light is adjustable.

4. The LED light of claim 1, wherein said housing contains multiple projection assemblies or heads aimed in different directions and arranged to swivel, rotate, or spin with said housing.

5. The LED light of claim 1, wherein the projection light only projects light beams to a distant surface.

6. The LED light of claim 1, wherein said housing has a position or orientation that is adjustable in three dimensions.

7. The LED light of claim 1, wherein the night light includes at least one second LED arranged to be turned on and off to selectively illuminate close areas while the at least one first LED serves as a projection light LED to illuminate distant areas.

8. The LED light of claim 1, wherein projection light includes an IC, timer, and time delay to achieve predetermined light performance effects.

9. An LED light, comprising:

a projection light including at least one first LED and projection parts including;

a sealed housing member including a tubular assembly for preventing light leakage, the LED being positioned such that light beams from the LED enter a first end of the tubular assembly;

an image forming element including at least one of a film, slide, display unit, LCD, TFT display, Lcos display, wireless digital display, changeable time display, weather display, and display screen; and

an optical projection lens at a second end of the tube for magnifying and projecting an image formed by said image forming element, said image being projected onto a surface at least an arm'"'"'s length away from said LED light; and

at least one night light including at least one second LED which forms a means for illuminating an area near the LED light in a dark environment,

wherein said at least one projection light being arranged to project at least one of the following images;

time, weather information, messages, digital data, cartoon characters, advertisements, seasonal data, promotion art, graphics, and light beams only, and

wherein at least one of the projection light and night light is arranged to be turned on and off to achieve predetermined functions, effects or performance in response to a switch, sensor, manual control or wireless control,

wherein the LED light has a base arranged to install the LED light on a surface without any movement of the LED light,

wherein the at least one second LED which forms a means for illuminating an area near the LED light is installed in said base,

wherein the LED light further includes swivel, rotate, or spin means for enabling movement of the projection light by swiveling, rotating, or spinning said housing, said at least one first LED, and said projection light parts, relative to said base and said night light in order to project said images in any of a plurality of selected directions such that the projection light is movable relative to the night light, and

wherein the LED light is powered by one of;

(A) alternating current (AC) input through prongs plugged into an outlet and circuitry for converting the input AC into an LED circuit working current; and

(B) direct current (DC) from a battery, USB wired power source, USB backup power source, solar power source, wind power source, generator power source, transformer having a DC power output, an adaptor having a DC power output, and a DC power storage element.

10. The LED light of claim 9, wherein the night light is a pin-hole device which has plurality of pin-hole sized openings, cutouts, or holes which allow passage of light from the at least one second LED to form enlarged images of the openings, cutouts, holes on a ceiling or on walls that are at a higher location than the night light'"'"'s plurality of pin-hole sized openings, cutouts, holes.

11. The LED light of claim 9, further including a second projection light for projecting a second image to a surface at least one arm'"'"'s length away from the LED light.

12. The LED light of claim 9, wherein the night light has the following additional functions:

a. a power failure light or emergency light powered by backup batteries;

b. a motion sensor light which turns on the projection light when a person is within a predetermined distance and turns off after a predetermined period of time;

c. a remote control or wireless control night light which turns on or off in response to signals from an infrared transmitter, a Bluetooth transmitter, an RF transmitter, a WiFi router transmitter, or a wireless controller.
