Description

  • This application is a divisional of U.S. patent application Ser. No. 12/292,153, filed Nov. 12, 2008, and incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • This application has subject matter in common with U.S. patent application Ser. Nos. 12/318,470 (“Projection Night Light”); 12/318,473 (“LED Night Light Has Laser or Hologram Element(s)”); 12/073,889 (“LED track light device”); 12/073,095 (“LED light with changeable position with Preferred power source”); 12/007,076 (“LED light with changeable geometric system”); 12/003,691 (“LED light with changeable geometric dimension features”); 12/003,809 (“LED light with changeable features”); 11/806,711 (“Multiple LED light with adjustable angle features”); 11/527,631 (“LED Night light with interchangeable display unit”) 11/498,881 (“Poly Night light”); 11/255,981 (“Multiple light source Night Light”); 11/094,215 (“LED Night light with Liquid optics medium”); 11/092,741 (“Night light with fiber optics”); 10/883,747 (“Fiber Optic light kits for footwear”); 11/498,874 (“Area Illumination for LED night light”); 11/527,629 (“Time Piece with LED night light”) 11/527,628 (“Multiple Function Night light with Air Freshener”); 11/806,284 (“U.S. Patent Application LED Night light with more than one optics mediums”); 11/806,285 (“LED Night Light with multiple function”); and 11/806,711 (“Multiple LEDs Light with adjustable angle function”).
  • The current invention provides a light image on a wall, ceiling, floor, other desired surface such as an optic means surface, or any other desired location to enable people to view a desired image such as a star, moon, planet, silver-river, universal image, cartoon character, family photos, or favorite image to cause people pleasure in a dark environment or when falling asleep in a nice environment. It is especially important for youth or kids' room applications to let them have their own favorite image surround them.
  • The current invention has the following features:
  • 1. It incorporates a simple optics-assembly to provide the projection features, the optics-assembly including a slide located between the LED and first optics means to enable easy assembly without the need for strict position and angle determination.
  • 2. The slide may be a disc with a plurality of slides that can easily be changed by just rotating the disc to easily change the image in upgraded models.
  • 3. The invention may incorporate a position change means for positioning a projector head to change image position, location, and/or size as desired by a simple touch, rotation, push, bend, or twist, so that any outside force applied to the night light cause the image to change position, location, or size instantly.
  • 4. The current invention can have compact dimensions when incorporated with a simple optics-assembly which allows the distance from LED tip to slide to be reduced to zero so that the slide contacts the first optics means.
  • 5. The current invention has no hazardous material such as a glass lens, but instead uses a hinge box with projector means inside to provide the precise positioning needed for a variety of lens types.
  • 6. The current invention may be incorporated with adjustable-focus means to adjust the lens distance to fit a variety of indoor spaces to keep any image perfectly clear.
  • 7. The current invention-may incorporate a transforming construction to change the projector head to a variety of positions and create an image at any desired location.
  • 8. The current invention provides an image surface that is perpendicular to the light beam path, for example a ceiling so that the image can be seen while asleep. Some prior art image projectors on top of a night light need too many expensive and fragile lenses, such as a reflective lens, condensing lens, grating lens, or projection/object lens that must be slid between these complicated lenses, causing a lot of limitations for mass production and night light unit dimensions.
  • 9. The night light of the current invention can fit a majority of market available housings and meet U.S. safety standard requirements.
  • 10. The night light of the current invention may have an adjustable distance between the light source(s) and the optics means (openings, films, hologram means, or grating means) to provide a clear image on desired surface(s).
  • 11. The night light of the current invention may have a new arrangement for battery position, location, and orientation to allow the light source(s) to have the best position and hit the optics means to get the best light effects and performance.
  • 12. The night light of the current invention may have a spiral arrangement for the batteries so that the light source(s) may be put on near center locations and emit light to an edge with a desired distance from the light source(s) to the optics means. It also can cover certain angled areas of all walls areas. This will get the best light performance and image size when applied to a hologram or grating laser film application.
  • The current invention represents a big improvement over all U.S. prior art including the following U.S. patents:
  • Prior art U.S. Pat. No. 5,517,264 (Sutton) discloses a projection night light with a preferred 7 Watt bulb (408) which radiates too much heat so that a big distance from the bulb to the optics means is required. Because of the super high heat from the 7 Watt Bulb, the night light requires use of a glass material which is very big and dangerous to a user. Furthermore, the Sutton concept of using a glass reflection lens (604) to enable the image to be seen on the display screen (102) requires too complicated a construction and is not practical for a low cost application. In addition, the glass lens is much too fragile, and also is too heavy for the prongs to stay tightly in the outlet.
  • Prior art U.S. Pat. No. 7,267,444 (Black, Jr.) discloses a projection night light which has the same problems as Sutton's, including use of too many lenses including (303) reflector mirror, (105) (405) condensing lens, (106) (406) adjusting lens, (403) grating lens (which grating lens corresponds to the one disclosed in the inventor's U.S. Pat. No. 5,667,736), and (415) project/object lens. Some of these lens need to made of a glass material which is very fragile and will be broken because it is too heavy to hold tightly in an outlet. The Black patent also emphasizes that the night light disclosed therein projects an image onto a surface parallel to a path of the light beam, through the use of projection means on top of the night light's wall. This is the reason why Black needs a lot of special optics lenses and slides (109) (209) (309) (409) between the glass lens.
  • Other prior art includes:
  • U.S. Pat. No. 6,824,296—Souze et al—Rotating lens with Bulb (78).
  • U.S. Pat. No. 6,889,918—Yaniv—Projector is wearable and projects an image onto screen (12).
  • U.S. Pat. No. 7,329,035—Feliciano—Child Night Light for held or worn.
  • U.S. Pat. No. 7,438,446—McCann—Projector inside a hinged top box (20), None of these can pass a USA safety standard because they will pass weight and pulling tests. Not safe and not qualified at all.
  • The current invention of an LED light for night time use includes: (A) a plug-in wall outlet night light, or (B) a direct current (DC) operated night light with projection features to project an image, message, data, logo, or time onto a ceiling, walls, floor, optic means surface or any other desired surface.
  • The current invention has as a light source an LED or plurality of LEDs (such as disclosed in copending U.S. patent application Ser. No. 11/255,981, now allowed) to supply a visible light beam to pass through an optics means or more than one of the optics means (such as disclosed in copending U.S. patent application Ser. No. 11/806,284) and create an image on a desired surface or location with additional features preferably selected from the group including size, dimension, area, height, distance, color, brightness, time period, trigger means, light function, light performance, changeable focus, changeable slides, changeable geometric shape of the night light, and changeable projection head direction.
  • The current invention incorporates preferred optics means selected from the group consisting of an optics-lens, concave lens, openings, cut-outs, film, grating means, hologram means (such as disclosed in the inventor's U.S. Pat. No. 5,667,736) to create a preferred image at a desired location or surface.
  • The current invention combines various teachings of the inventor's copending U.S. patent application Ser. Nos. 11/255,981 and 11/806,284 for more than one light source and optics means with teachings of the inventor's U.S. Pat.

  • FIG. 7-1 shows a direct current operated LED night light (71) with projection features. At least one LED (71 i) serves as a light source to supply visible light beams. At least one of the optics-means (71 d) for use with LED (71 i) or LEDs (71 h) may be selected from the group including an optics-lens (71 b), film, openings, cut-outs, transparent material piece, translucent material piece, grating means (71 d), and hologram means (71 d) to create a desired image (not shown), message, data, logo, or time on a ceiling, walls, floor, desired surface, or the optics means surface (71 d). At least one of the power source (not shown), circuit means (71 h), and trigger means (71 q) is arranged to work with the LED (71 i) or LEDs (71 h) to obtained a desired light function, timing, colors, brightness, illumination, and/or light effects. The improved night light device (71) with projection features is a direct current (D.C.) power source night light which can be turned on when the housing (71 b) is touched or pushed. The said direct current power source may be in the form of an AC adaptor with a jack, or a solar power source, wind power source, chemical power source, generator power source, or any direct current power source available from the market.
  • As shown in FIG. 7-1, the laser processed film or injected piece (71 d) is in the form of a circle shape (1 d) arranged to fit into the top housing (71 a) at the position (71 x). The laser processed film or injected piece (71 d) is situated a distance D from the light source (71 p). The distance D is very important when making the laser processed film or injected piece. The distance D is fixed, and then the laser process film or injected piece is arranged to form a desired image on the laser processed film or injected piece. The laser processed film or injected piece can provide a desired image depending on the distance D, which determines the number of images, the size of the images, configuration of the images. It will therefore be appreciated that the distance (D) between the processed film or injected piece and the light source (71 p) is very important to enable a perfect laser image to be shown on the surface of the processed film or injected piece.
  • As shown in FIG. 7-1, the LED (71 i) is installed on a printed circuit board (71 h) on a base (71 f). The height of base (71 f) can be adjusted within distance (dd1). The adjust-means of this preferred embodiment has a screw-nut (71 m) with a center hole (71 k) to receive a screw-bolt (71 j) to allow the base (71 f) to adjust the height of the LED position. The LED (71 i) and other LEDs can emit light to the laser processed film (71 d) when the LED or LEDs are arranged to emit light to the laser processed film (71 d). This embodiment can provide a very pretty color image on the walls (71 c).
  • As shown in FIG. 7-2, the laser processed film or injected piece (72 c) is positioned in a horizontal position (72 d) on top housing (72 b) so that the image will be seen on a top area of the DC powered night light (72). The adjustable means in this preferred embodiment uses detents (72 j) and a receiving hole (72 k) to hold position at a certain height. The LED or LEDs (72 i) on the base (72 h) can therefore have an adjustable height to change the distance (D) between the laser processed film (72 c) and light source (72 h) and change the image. The adjustable means has an LED height adjustment range (dd2).
  • As shown in FIG. 7-3, a wall (75 a) is located on the lower housing (75 b). The adjustable means (75 d) (75 e) has a height adjustable range (dd3) to change height of LEDs (75 c) relative to PCB (75(c).
  • FIG. 7-4 shows one preferred arrangement for enabling the laser processed film (76 b) to fit into a dome shaped top housing (76 a). The flat film cannot fit into the ball shaped dome, so multiple cuts (76 b) (76 c) (76 d) (76 e) (76 f) must be made into the film. This is an economical arrangement to make a low-end product. An upgraded model with an injected piece may utilize the grating or hologram techniques disclosed in the inventor's prior art U.S. Pat. No. 5,667,736.
  • FIG. 7-5 an arrangement of the LED or LEDs on a PCB in the lower housing. The PCB can be any size as long as it is smaller than the lower housing. The LED or LEDs can be arranged on the center area or edge of the PCB to face upward or outward for different requirements to vary the distance (D) between the laser processed film or injected piece and the light source.
  • FIG. 7-6 shows a direct current operated LED night light with projection features in which at least one LED (73 i) serves as a light source to supply visible light beams, and least one optics-means (73 a) for use with the LED or LEDs is selected from the group including an optics-lens, film, openings (star) (planet), cut-outs (moon), transparent material piece, translucent material piece (73 a), grating means, and hologram means to create a desired image, message, data, logo, or time on a ceiling, walls, floor, desired surface, or optics means surface. At least one of a power source (73 m) (73 m′) (73 m″) (73 m′″), circuit means (73 h), and trigger means (73 o) is arranged to work with the LED or LEDs (73 i) to obtain a desired light function, timing, colors, brightness, illumination, and/or light effects. The LED night light device (73) with projection features is a direct current (D.C.) power source night light which can be turned on when the housing (73 a) has been touched or pushed. The direct current power source (73 m) (73 m′) (73 m″) (73 m″″) may take the form of an AC adaptor with a jack, or a solar power source, wind power source, chemical power source, generator power source, or any direct current power source available from the market.
  • As shown in FIG. 7-6, the DC operated LED night light with projection features (73) has a top housing (73 a) with a plurality of openings (stars) (moon) (planet) or cut-outs on a transparent material piece (73 a). The top housing 973 a) has a foldable skirt (73 d) which can adjust the height of the top housing, including an optics-lens (73 a), to a higher or lower location to change the distance (D) between the optics-lens (73 a) and light source (73 i). The adjustable means can alternatively be provide on the LED's or LEDs' base (73 h) to make the height adjustable from the LED base. The adjustable skirt (73 d) or adjustable means on the LED base are preferred examples, but it will be appreciated that any functionally similar or equivalent construction may still fall within the current invention scope, so long as it makes the distance between the optics-means and light source adjustable to get a clear image on the desired surface to fit all kind of room or space.
  • FIG. 7-7 shows a DC operated night light having a top optics-lens (74 b) with a plurality of openings or cut-outs (star) (moon) (planets) to allow the LED light beam to be emitted spread out to the desired surface. The trigger means (74 c) are always kept in a same position against the top optics-lens (74 b) and will be triggered when the top optics-lens been touched or pushed to turn the LED on and off. In order to get a clear projection image on a desired surface, the adjustable means (not shown) are provided on the LEDs' base to allow the LEDs (74 f) to be moved up or down to provide a clear image for different rooms or space.
  • As shown in FIGS. 7-6 and 7-7, a preferred arrangement of batteries (73 m) (73 m′) (73 m″) (73 m″″) in a spiral spaced allows a plurality of LEDs (73K) (73 j) (74 h) (74 h′) (74 h″) to be installed as close to center as possible to increase the distance between the light source and optics means such as openings, cut-outs, laser processed film or an injected piece when applied to a wall location. The larger distance will create more exciting image or projection effects.
  • As shown in FIG. 7-6, LEDs (73 j) (73 k) are situated very close to a center position so their light beams will spread out to the wall areas and hit the optics-means including openings, cut-outs, laser processed film or an injected piece to provide excellent image or projection effects on a desired surface. If the LEDs are too close to the wall area, then the effects will be limited and the laser tooling work become very difficult. Normally, a 2-10 cm+/−50% distance between a laser processed film or injected piece and the light source is very good and enables use of a variety of available laser processed films or injected pieces available from the marketplace so there will be no need for a big investment in laser tooling for too short a distance application.
  • FIGS. 7-8, 7-9, 7-10 show three preferred embodiments having different distances (d4) (d5) (d6) between the top optics-lens (77 a) 978 a) (79 a) and light source (77 f) (78 f) (79 c). The top optics-lens may be in the form of openings, cut-outs, laser processed film or an injected piece. The night light of this embodiment also has adjustable means (77 h) (79 e) with a height adjustable range for (dd4) (dd6) that enables a clear and exciting image to be shown or projected on the desired surfaces. All of these preferred embodiments have DC operated power utilizing batteries and/or a variety of input power sources as discussed above.
  • FIGS. 7, 8, 9, and 10 show preferred projection DC operated night lights with special configuration (7 d) (8 d 1)(8 d 2) (8 d 3) (8 d 4) (9 a) (9 b) (10 d 1) (10 d 2) of openings or cut-outs on the top optics-lens. Some models also have the openings, cut-outs, laser processed film, or an injected piece on walls (7 c) (8 e) (9 c) (10 e) to allow the projection or image to be seen on a desired surface.
  • FIGS. 11, 12, 13, and 14 show a preferred laser image on a DC operated night light with special configurations of laser image including stars (11 d 3) (11 d 4), dots (11 d 1) (12 d 1) (13 d 1) (14 d 1), a silver river (11 d 2) (12 d 4) (13 d 2) (14 d 4), moon (11 d 3) 914 d 1), planet (not shown), sun, (not shown) or other desired image on the top optic-lens and on the wall (12 e).
  • It will be appreciated by those skilled in the art that the projection and image optics effects can be present in the same unit because both use LED or LEDs as a light source as long as suitable openings, cut-outs, laser processed film or injected pieces are applied to the top optics-lens or wall.
  • FIGS. 15, 18, and 19 show a preferred DC operated night light for image (18 b) (18 c) projection or for displaying an image on a desired surface through the wall (15 b) with a dollar sign by an opening, cut-outs, or laser processed film or injected piece. The lower housing (19 a) has a battery compartment (19 b) and switch (19 c) with assembly poles (19 f) (10 f′) (19 f″) (19 f′″) and spring members (19 g) (19 g′) (19″) (19′″) to bias the top optics-lens (15 c) to an upward position so that pushing the top optics-lens (15 c) will turn the LED on and off LED. The LED or LEDs (19 h 2) are positioned on a PCB (19 e) and connected with the power source by conductive wires (19 d) to supply the electric signals that turn the LED or LEDs on and off to obtain pre-determined functions, brightness, color, effects, and/or performance. The plurality of LEDs also can be installed along the battery compartment edge, but this is not the best arrangement. The best arrangement would be similar to that shown in FIGS. 7-5, 7-6, and 7-7 to provide a larger distance between the light source and optics-means as discussed above, in which case the plurality of LEDs along the battery compartment will create an exciting projection or image on the desired surface.
  • FIGS. 16, 17, and 20 show an arrangement that is similar to that shown in FIGS. 15, 18, and 19. The major differences are that the plurality of LEDs emit light beams inwardly towards a circle reflector (20 j) and get a lot of light spots on the reflector (20 j), the light spots then hitting the optics-means (17 a) surrounding the wall of the night light. This teaching of adding the extra reflectors means on the night light is helpful to increase the number of light spots.
  • This application includes subject matter in common with copending U.S. patent application Ser. No. 12/318,470 (“LED night light with Project features”), and any concepts, drawings, and designs disclosed therein that are applicable to the current invention should fall within the scope of the present application, including any equivalent, same function or replaceable alternative arrangement.
  • While the above-discussed and mentioned preferred embodiments help illustrate the scope of the current invention, it is to be appreciated that any alternative or equivalent functions of design, construction, modification, or upgrade may still fall within the scope of the invention, and that the current invention is not limited to the details described or mentioned above. Any alternative or equivalent arrangement, process, installation, design, or changes from the current invention may still fall within the scope of the current invention, including variations in the power source, conductive means, geometric shape of LED-units, connector-means, circuit means, sensor means, switch means, LED elements, attachment means, fixing-means, tightening means, resilient conductive means, and so forth.
