Abstract

An LED night light having different power sources including a battery, outlet plug-in power source, or interchangeable power source incorporates more than one reflective means with desired relative positions, distances, and/or orientations to create plurality of LED or LEDs image on at least one surface of the night light. At least one of the reflective means can be a see-though surface to permit the plurality of LED images to be seen through the reflective means. An LED light device having power and cost saving features is also provided.

Claims

1. An LED night light having more than one reflective means for reflecting light from at least one LED to create a plurality of LED images, comprising:

at least one LED;

a first reflective means having a first partially reflective surface; and

at least one second reflective means having a reflecting surface for reflecting light from the first partially reflective surface of the first reflective means back to the first reflective means, said first reflective means reflecting said light to obtain multiple reflections of the LED between the two reflection means,

wherein said at least one LED is situated on one of said first surface of the first reflective means and said first surface of the second reflective means,

wherein said first reflective means is for reflecting light from said at least one LED and from said first surface of the second reflective means to cause multiple reflections of the light from the at least one LED, said multiple reflections of light then passing through said first reflective means such that multiple images of said at least one LED are visible on a second surface of said first reflective means,

wherein an arrangement of said multiple images of said at least one LED are visible on said second surface of the first reflective means is determined by a position, distance, angle, or orientation of said first reflective means relative to said second reflective means, and

wherein said at least one LED are connected to a power source by conductors and circuitry including means for causing said at least one LED to turn on and off for a predetermined period to provide predetermined functions, colors, and effects.

2. An LED night light with more than one reflective means as recited in claim 1, wherein said first reflective means is selected from the group consisting of a mirror, chrome-finished piece, fine-polished piece, and double-sided mirror.

3. An LED night light with more than one reflective means as recited in claim 1, wherein said see-through properties are provided by a transparent or colored transparent piece of said first reflective means.

4. An LED night light with more than one reflective means as recited in claim 1, wherein said power source is selected from the group consisting of an outlet, batteries, solar power, chemical power, and wind power to provide electricity to drive said at least one LED to emit light beams.

5. An LED night light with more than one reflective means as recited in claim 1, wherein additional reflective means are positioned in three dimensional space at a top and sides of said night light to provide a desired number and arrangement of said images.

6. An LED night light with more than one reflective means as recited in claim 1, wherein said at least one LED is selected from a single or multiple color LED, a multiple piece LED, a standard LED, and a custom LED assembly.

7. An LED night light with more than one reflective means as recited in claim 1, wherein a distance, position, or orientation of said first reflective means relative to said second reflective means is varied to change a number, position, geometric arrangement, or brightness of said plurality of images of said at least one LED.
