Abstract: An interchangeable power source light device has an AC power sealed-unit that fits into a uniform compartment of the light device housing. The AC power sealed-unit can be replaced by a DC power battery-pack, which also fits into the uniform compartment-means of the light device housing. The light device may have a built-in light source within the housing for connection with the sealed-unit or battery unit by to deliver electric signals from the sealed-unit or battery pack to the light source. Each sealed-unit and battery pack not only has its own power source, but also circuitry and a trigger, and optionally other light source(s) having low power consumption such as an LED(s), electro-luminescent (EL) element, organic LED, or organic EL element.

Abstract: A projector apparatus that may include a first plurality of adjacent translucent lenses on at least one side of an inner lens, said inner lens configured to rotate and translate about an axis (A) of the inner lens; a second plurality of adjacent translucent lenses formed on at least one side of a concave outer lens; a light source configured to direct a portion of light through the rotatable and translatable inner lens and then through the concave outer lens; and a motor configured to rotatably and translatably drive the inner lens in an oscillating manner about and along the axis of the concave inner lens (A); so that the oscillating inner lens imparts a moving textured image for modification through the fixed concave outer lens for display upon a surface, such as a ceiling to simulate a moving liquid surface.

Abstract: An LED light has surrounding lighted geometric art patterns shown on the LED light location's wall. The said LED light power by (1)AC or (2)DC power source though circuit and related electric parts & accessories to make built-in LED(s) to turn on and turn off for predetermined light effects including color changing, fade-in & fade-out and other moving LED(s) effects while LED are install within the main housing on different locations or height or multiple height to emit the light to all directions in order to cover certain range of the said housing and incorporate with decorative piece or slide, printed film or character slide, holes, shaped cutouts, windows with design to form the lighted geometric art pattern surround the said LED light.

Abstract: This invention introduces a variable-speed text projector that consists of two concentric cylinders and uses the convection of heat from a central light bulb to rotate the inner cylinder. A circular cover that fits onto the larger outer cylinder (projection screen). This circular cover controls the speed of the rotation of the inner cylinder. By venting the heat emitted by the bulb (controlling heat flow) in small to large increments, the cover adjusts the speed of the moving text. This constructed top is necessary to this device. The preferred embodiment provides an ease of facility and control of speed to the user who desires to read the text in comfort.
