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.
