Abstract

An LED and/or laser light for night time or dark area use, such as a plug-in wall outlet night light or direct current (DC) operated desktop light, includes projection or pin-hole image features to project or present an image, message, data, logo, or time on a ceiling, walls, floor, or other desired surface, or an cover surface, inner housing wall. The optics piece surround light source including an optics-lens, slide, openings, cut-outs, film, grating, or holographic element to create an image at a desired location. The night light may have an adjustable angle or distance between light source and optics piece, as well as other adjustable position, location, or orientation features.

Claims (12)

1. A DC powered LED and/or laser light for displaying an image or light patterns, comprising:

at least one light source that includes at least one LED and/or laser;

a lower base; and

at least one optics piece that includes a cylindrical film having windows, pinholes, cutouts, printing, or painting for forming the image or light patterns when light from the at least one light source passes through the film,

wherein the cylindrical film extends around the DC powered LED and/or laser light and is assembled to the base,

wherein light from the at least one light source passes through the at least one optics piece to create the image or light patterns, and

wherein the at least one light source is mounted on the lower base by a height-adjustment kit for adjusting a distance of the at least one light source from the base, whereby adjustment of the height of the at least one light source relative to the base changes said image or light patterns.

2. A DC powered LED and/or laser light for illumination or displaying an image or light patterns as claimed in claim 1 , wherein the at least one LED is one of a chip, dice, or DIP having at least one of a (1) single color, (2) multiple colors, or (3) a plurality of different colors inside one LED.

3. A DC powered LED and/or laser light for illumination or displaying an image or light patterns as claimed in claim 1 , further comprising a top cover, wherein the top cover is opaque, whitened, or injected with opaque or white colors.

4. A DC powered LED and/or laser light for illumination or displaying an image or light patterns as claimed in claim 1 , wherein the LED and/or laser light exhibits at least one of a fixed, changeable, moving, or rotating light effect or function.

5. A DC powered LED and/or laser light for illumination or displaying an image or light patterns as claimed in claim 1 , wherein the adjustment kit comprises a bolt extending from the base and a nut to which the at least one light source is fixed.

6. A DC powered LED and/or laser light for illumination or displaying an image or light patterns as claimed in claim 1 , wherein the adjustment kit comprises a detented member extending from the and an annular structure to which the light source is fixed and which includes openings for receiving at least one of said detents to adjust the height of the light source relative to the base.
