Abstract
An LED night light for night time or dark area use may be arranged as a plug-in wall outlet night light or a direct current that includes projection features to project an image, message, data, logo, and/or time on a ceiling, walls, floor, or other desired surface. The LED night light incorporates optics selected from an optics-lens, convex lens, concave lens, openings, cut-outs, film, grating means, and/or hologram means to create the preferred image and project it to a desired location.
Claims10
A night light with projection features, comprising:
- at least one LED arranged as a light source to supply visible light beams;
- at least one optics means for projecting an image on a desired surface, said optics means selected from the group consisting of an optics lens, a convex or concave lens, telescope means, a film, a display unit, a transparent material, and a translucent material, said image being formed by light from said at least one LED passing through transparent areas, openings, cut outs, grating means, or hologram means in said optics means, said image being selected from the group consisting of a message, data, a logo, a time, and any other image desired to be projected on said desired surface, and said desired surface selected from the group consisting of a ceiling, a wall, a floor, and any other surface that is outside said plug-in night light;
- and
- at least one power source, circuit means, and trigger means arranged to cause said at least one LED to exhibit desired light functions, timing, colors, brightness, and illumination,
- the improvement wherein:
- said night light with projection features is a night light arranged to be plugged into an electrical outlet.
