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. |

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; andan 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. |
