LED night light has projection or image feature

Abstract

An LED night light for night time or dark area use, such as a plug-in wall outlet night light or direct current (DC) operated night light, includes projection or image features to project or present an image, message, data, logo, or time on a ceiling, walls, floor, or other desired surface, or an optics element surface. The optics means may include an optics-lens, slide, convex lens, concave lens, 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-means, as well as other adjustable position, location, or orientation features.

AI Technical Summary

Problems solved by technology

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.

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.

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.

Not safe and not qualified at all.
