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 power saving features, comprising:

at least one LED arranged to provide a light source;

at least one housing with space to install control means for causing said at least one LED to turn on and off, the at least one LED being further controlled by components within said housing including at least one of a switch, sensor, timer, auto activation circuitry, and integrated circuit, said components being connected by conductive means to a power source,

wherein the at least one LED is turned on and off by said control means 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, and

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