DETAIL DESCRIPTION

The LED night light with projection features of current invention is different from convention market place's projection pen, projection key chain, projection toy, or commercial presentation projection equipment.

The current invention mainly for the night light applications with LED or LEDs as light source to directly plug into outlet device, so the circuit need to be special design to fit for the AC 110V 60 Hz input power to drive the said LED or LEDs.

The current invention incorporated optics-means which may selected from group combination from optics-lens, slides, openings, cut-outs, transparent material piece, translucent material piece, telescope assembly, housing-member, slide-disc, roller-means, elastic-member, tilt-means, rotating-means, adjust-means, roller-means, mechanic-means, extend-means, convex lens, concave lens, with precision optics calculation and optics design to make the said image, message, logo, characters, sign, time, data to project on the desired surface such as ceiling, walls, floor, or any location as wished.

The current invention also disclosure the geometric design for the whole night light, it is not limited to the preferred embodiments. The alternative construction for the night light with tilt, swivel, rotating, projection position change, focus adjustable, change slides features should still fall within the current invention scope.

From FIG. 1, The LED projection night light (1) has telescope assembly (1b) fit within the body with top opening (1e) to project the image to top area for certain size (1g) with certain distance from the opening (1e). The night light body has build in mechanic-means to install the roller-means (1c) with plurality of slides (1d) (1d′) (1d″) so the people can change slides at any time and project the different image on the area (1g).

From FIG. 1-1, disclosure the telescope-assembly which has the housing-member (1-1) with object-end (1-2) and eye-end (1-3) which has preferred optics lens (1-5) and lens (1-6) and slide (1-6) for each end. The lens (1-7) and slide (1-6) can have different position as drawing for different image requirement. The arrangement (A) convex lens face inside so can make income LED light beam become parallel light beams to hit the slide so the image will be very clear. The arrangement (B) or (C) make not a big difference for the Image but is not clear as the arrangement (A). Some alternative arrangements for telescope-assembly still fall within the scope of current invention. The preferred several construction similar with the FIG. 9-1 listed. The Optics lens, telescope length, lens diameter, focus can be well designed to get desire image quality, size out of the LED projection night light.

From FIG. 1-2, The roller-means has base (1-10) which has certain holes (1-11) (1-11′) (1-11″) and pole (1-12) (1-13) to hold the plurality slides on position and also receive the income LED light bean to hit the one of the slide to project the slide colorful image to the desired location on certain distance. Some application no need the roller-means for plurality of slide film as long as the slide-film has fix-holes, it is no need any roller-means to help to hold slide-film. The current embodiment because need let people to rotate the roller-means so need this roller-means to let people can touch and make change slides.

From FIG. 2 disclosure The plug-in LED night light (2a) with projection features. At least one LED (not shown) as light source to supply visible light beams. At least one of the Telescope optics-means (2d) incorporate with said LED or LEDs or slide(s)-film (2i), film, openings (2e), cut-outs (2f), transparent material piece (2m), 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 (2b), circuit means (inside of 2a), trigger means (2c) arranged to work with the said LED or LEDs to get desired light function, timing, colors, brightness, illumination. The said LED projection night light device (2a) has the changeable slide (2i), film, angle, projection position, orientation, light functions, light effects features. From FIG. 2, The current invention also use co-pending filing for “sealed-unit” which has all electric components including prong, circuit, trigger means, LED or LED connector within to get AC power source to turn on and turn off the said LEDs. The “sealed-unit” also can be replaced by battery-pack which has all electric components within including batteries, circuit, trigger means, LED or LED connectors within to make the said night light illumination under pre-determined function, timing, duration, effects. The “sealed unit” has more details on following copending filing case with Fig S and all details description:

(1) U.S. patent Application LED Night light with interchangeable display unit, Ser. No. 11/527,631.
(2) U.S. patent application of Ser. No. 11/498,881, Poly Night light
(3) U.S. patent application of Ser. No. 11/255,981, Multiple light source Night Light.
(4) U.S. patent application LED Night light with Liquid optics medium Ser. No. 11/094,215, filed Mar. 30 2005.

The said LED light with base to has empty inner space to fit the above discussed circuit-means, sensor-means, switch-means, timer-means, IC-means, prong-means etc. It is appreciated all these electric components can fit into a “sealed-unit” as co-pending filing description as (1) U.S. patent application LED Night light with interchangeable display unit, Ser. No. 11/527,631. (2) U.S. patent Application of Ser. No. 11/498,881, Poly Night light (3) U.S. patent Application of Ser. No. 11/255,981, Multiple light source Night Light. (4) U.S. patent application LED Night light with Liquid optics medium Ser. No. 11/094,215, filed Mar. 30 2005.

The “sealed-unit” it has its own power, LED, circuit-means, attachment means so can fit into any LED light housing as long as there have uniform compartment. The said “AC powered sealed unit” t related to the 110 Volt 60 Hz or other high voltage connection issue so the said sealed unit have to meet all safety standard to make sure without any hazard, electric shortage, potential damage under laboratory multiple testament standard and procedure with related safety certification.
