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.
Claims5
A light emitting diode (LED) night light with projection features, comprising:
- at least one LED that serves as a light source for visible light beams;
- at least one optics-means including parts selected from the group consisting of a slide, film, openings, cut-outs, transparent material piece, translucent material piece, grating, and hologram that form, or on which is formed, a representation of said image, message, data, logo, or time;
- and
- at least one of a power source, circuit means, and trigger means arranged to work with said at least one LED to provide at lease one of a desired light function, timing, colors, brightness, and illumination;
- the improvement comprising:
- a projection lens element;
- and
- a sealed housing,
- wherein said projection lens element is at one end of said sealed housing and said LED is at another end of the sealed housing with said optics means therebetween, said projection lens element and optics means being arranged perpendicularly to said light beams such that said light beams pass through said optics means and projection lens element to project said image, message, data, logo, or time onto a ceiling, wall, floor, or desired surface that is also perpendicular to said light beams,
- wherein said image, message, data, logo, message, or time projected by said optic means is multiple times larger than said representation of said image, message, data, logo, or time formed on said optics means, and
- said LED night light is a plug-in type night light arranged to be connected with an outlet device.
