Abstract

The current invention for LED night light for night time or dark area use including plug-in wall outlet night light or direct current operated night light with projection features to project the image, message, data, logo, time on ceiling, walls, floor, desired surface. The said LED night light incorporated with optics means may selected from group combination from optics-lens, convex lens, concave lens, openings, cut-outs, film, grating means, hologram means (same as inventor'"'"'s U.S. Pat. No. 5,667,736) to create the preferred image on the desired location to let viewer to see.

Claims

1. The plug-in LED night light with projection features consist of;

At least one LED as light source to supply visible light beams to viewer.

At least one of the optics-means incorporate with said LED or LEDs which may selected from group combination from optics-lens, film, openings, cut-outs, transparent material, translucent material, grating means, hologram means to project the desired image, message, data, logo, time on ceiling, walls, floor, desired surface.

At least one of the power source, circuit means, trigger means arranged to work with the said LED or LEDs to get desired light function, timing, colors, brightness, illumination.

The improvement including;

The said LED night light device with projection features is a plug-in type night light to connect with the outlet device.

3. The LED night light with projection features as claim 1, the said LED night light incorporated with circuit-means to make the desired light functions may selected from ground combination from fade-in and fade out, automatically changing color, sequential, random, chasing, pair flashing, time delay, time period selection, steady on, photo sensor, motion sensor, brightness changing, color changing, rotating or any available light functions available from market place.

4. The LED night light with projection features as claim 1, the optic-means may selected from group combination from optics-lens, convex lens, telescope means, concave lens, openings, cut-outs, film, grating means, hologram means (same as inventor'"'"'s U.S. Pat. No. 5,667,736) to create the preferred image on the desired location to let viewer to see.

5. The LED night light with projection features as claim 1, the optics-means has geometric shape may selected from sphere, ball, half-ball, to make the image been project to x-y-z axis surface.

6. The LED night light with projection features as claim 1, the telescope with adjustable features so can change focus.

7. The LED night light with projection features as claim 1, the said LED and LEDs connected with circuit-means which may selected from group combination from circuit board, integrated circuit, conductive means, switch means, AC jack, solar module, AC plug and wire, AC adaptor, sensor means, motion sensor means, timer means to make the desired light functions and effects.

2. The Direct Current operated LED night light with projection features consist of;

At least one LED as light source to supply visible light beams to viewer.

At least one of the optics-means incorporate with said LED or LEDs which may selected from group combination from optics-lens, film, openings, cut-outs, transparent material, translucent material, grating means, hologram means to create the desired image, message, data, logo, time on ceiling, walls, floor, desired surface.

At least one of the power source, circuit means, trigger means arranged to work with the said LED or LEDs to get desired light function, timing, colors, brightness, illumination, light effects.

The improvement including;

The said LED night light device with projection features is a direct current (D.C.) power source night light which can be turn on while the optics-lens been touched, pushed.

The said direct current (D.C.) power source means the electric signal into the said LED or LEDs is direct current which may form AC adaptor with jack, solar power source, wind power source, Chemical power, generator power, or any Direct Power source available from market.

8. The LED night light with projection features as claim 2, the said LED night light incorporated with circuit-means to make the desired light functions may selected from ground combination from fade-in and fade out, automatically changing color, sequential, random, chasing, pair flashing, time delay, time period selection, steady on, photo sensor, motion sensor, brightness changing, color changing, rotating or any available light functions available from market place.

9. The LED night light with projection features as claim 2, the optic-means may selected from group combination from optics-lens, convex lens, telescope means, concave lens, openings, cut-outs, film, grating means, hologram means (same as inventor'"'"'s U.S. Pat. No. 5,667,736) to create the preferred image on the desired location to let viewer to see.

10. The LED night light with projection features as claim 2, the optics-means has geometric shape may selected from sphere, ball, half-ball, to make the image been project to x-y-z axis surface.

11. The LED night light with projection features as claim 2, the telescope with adjustable features so can change focus.

12. The LED night light with projection features as claim 2, the said LED and LEDs connected with circuit-means which may selected from group combination from circuit board, integrated circuit, conductive means, switch means, AC jack, solar module, AC plug and wire, AC adaptor, sensor means, motion sensor means, timer means to make the desired light functions and effects.
