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

9. An LED light, comprising:

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 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.

1. An LED light, comprising:

an LED light housing with movable parts to change image location or focus adjustable; 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 or housing or compartment assembly including a tube or compartment for preventing light leakage out of tube or compartment, the at least one LED being positioned desire location on 1^st side of tube or compartment such that LED light beams emit to display-unit or equivalent film or slide and lens or lens assembly; and

an optical projection lens or lens assembly fit within the walls or groove or ditch of the tube or compartment on other side for transforming the LED light beams into wider area light beams thereby magnify and project an image formed by an image forming element or display-unit or film or slide, 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 or compartment 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 with or without construction or assembly to change films, slide from plurality of films or slides, or—

and adjustable focus;

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

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 at least including one of the said the film, slide, plurality of slides/films loading disc, walls, groove, ditchs, holder to install the film, slide, lens, movable lens assembly to make the lens assembly movable to change focus,

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