Abstract

An LED light device with special effects utilizes persistence of vision theory to cause an LED(s) or LED array to change faster than the human eye response time of 1/16 to 1/24 second to display a special message, time, drawing, light patterns, or color changes. In addition, the light device may be provided with a sealed-unit arranged to receive a variety of eye-catching shades.

Claims

1. An LED light device with special effects, comprising:

at least one LED array arranged on a substrate;

at least one spin means having an axis, said substrate rotatably coupled to said spin means at said axis, and said spin means being for causing said substrate to rotate at a predetermined speed about said axis; and

a housing for housing said substrate and at least one LED array,

wherein the LEDs of said LED array are arranged to turn on and off according to a predetermined pattern, timing, color, and function to achieve predetermined lighting effects, the LEDs being controlled by components within said housing including at least one of a switch, sensor, timer, auto turn off and on circuitry, gear set, motor, and integrated circuit, said components being connected by conductive means to an AC, DC, or interchangeable AC and DC power source, said lighting effects selected from the group consisting of light patterns, a message display, a time display, a color changing display, a word display, a logo display, and an advertisement display,

wherein the LEDs are turned on and off in cycles to provide a persistence of vision effect, said cycles having a duration of less than the human eyes'"'"' response time of 1/16 to 1/24 second so that predetermined images will persist in the eye of an observer even though the LEDs are turned off for part of each cycle to save power, and

wherein said light device is a desk top or outlet plug-in light device.

2. An LED light device with special effects as claimed in claim 1, wherein said housing has a ball shape.

3. An LED light device with special effects as claimed in claim 1, wherein the spin means is a motor and said substrate forms fan blades in which said LED array is installed.

4. An LED light device with special effects as claimed in claim 1, wherein the spin means is a motor and said substrate forms bars in which said LED array is installed.

5. An LED light device with special effects as claimed in claim 1, wherein the spin means is a motor and said substrate forms a round disc in which said LED array is installed.

6. An LED light device with special effects as claimed in claim 1, wherein the spin means is a motor and said substrate is a frame substrate in which said LED array is installed.

7. An LED light device with special effects as claimed in claim 1, wherein the spin means is a motor and said substrate has a geometric shape in which said LED array is installed.

8. An LED light device with special effects, comprising:

at least one LED fitted into a laboratory-certified sealed unit and a receiving means for interchangeably receiving a variety of different shades to form a final LED light device,

wherein said shades are made of a material selected from the group consisting of plastic, paper, wood, laser pieces, hologram pieces, an air bag, a balloon, assembly pieces, light block-out elements, and a grill to provide said LED light device with said special effects and an eye-catching appearance,

wherein because all electrical parts are contained within said sealed unit, said final light device requires no additional laboratory certification when one of said shades is replaced by a different one of said shades, irrespective of the material of the shades,

wherein a power source for said LED light device is one of a battery power source, and electrical outlets, and interchangeable AC and DC power sources, and

wherein said light device is a desk top or outlet plug-in light device.

9. The LED light device of claim 8, wherein said shade is a balloon.
