Abstract

An LED light has a pinhole-imaging function for dark area use as a plug-in wall outlet light, direct current (DC) operated light, or interchangeable power source light to project a shaped image to a surrounding environment. Tiny shaped pinholes can create a fine image of desired message, data, logo, or time on a ceiling, walls, floor, optics means surface or other desired surface. At least one pinhole-means may be incorporated with an LED and parts selected from a housing-member, plastic film openings, cut-outs, transparent material piece, translucent material piece, adjust-means, sealed-unit, battery-pack, paper material, plastic material, metal material, wood material, geometric shape substrate, AC adaptor and jack means, and/or solar power or wind power generator to project the desired image, message, data, logo, to the surrounding environment, which may include any combination of ceiling, walls, floor, or other desired surfaces(s). The light may have an adjustable feature, interchangeable power source feature, dot-matrix gerometric shape feature, and features to change position or orientation of the pinhole substrate or LED.

Claims

1. An LED light system with interchangeable power sources comprising:

different LED light devices having a plurality of different geometric shapes, functions, applications, and features, wherein housings of said different LED light devices have a same uniform compartment, said same uniform compartment arranged to receive different power source units;

said different power source units including at least one AC powered LED sealed unit arranged to fit in said uniform compartment and certified to meet safety standards; and

said different power source units further including at least one DC powered LED battery pack also arranged to fit in said uniform compartment,

wherein said AC powered LED sealed unit and said DC powered LED battery pack each includes;

at least one LED arranged to serve as a light source for supplying visible light beams;

a power source and circuit means for supplying a trigger signal to said LED,

wherein said LED is triggered when the AC powered LED sealed unit or the DC powered LED battery pack supplies said trigger signal to the LED included therein, and

wherein because said different LED light devices have a same uniform compartment, said AC powered LED sealed unit and said DC powered LED battery pack may be received in each of said different LED light devices, to provide LED light devices having said plurality of different geometric shapes, functions, applications, and features that interchangeably receive any of said different power source units.
