A picture frame illuminated and decorated by several LEDs, distributed along the face of parallel sides, as well as top and bottom of the picture frame and controlled by software, which is programmed into a micro-controller. The lighted picture frame comprises of a printed circuit board, a motion detector element, a light sensor element, a push button, battery compartment, one or more one-color, bi-color or tri-color LED independently or collectively connected to printed circuit board by wires, or by printed wires. A current limiting resistor network is connected in series with LEDs. Electronic circuit is powered by a DC power source, which can be either battery or a DC adapter. LEDs flash and illuminate in different patterns and sequences controlled by software. LEDs are individually or collectively controlled by software, making it possible to create a variety of light and pattern combinations. Either the motion detector element or the push button can wake up the controller from sleep mode and restart program flow for a duration specified by software, before the micro-controller goes to sleep mode again. Frame can come in different shape, size and material such as wood, metal, glass, plastic, foam or any combination of different materials, and can be covered and decorated with different shapes and materials such as leather, aluminum, glass, ceramic, metal, etc. The illuminated frame has all elements found in a basic picture frame, such as easel back plate, transparent plate, etc. Printed circuit board and battery can be installed in a compartment within the body of the picture frame, covered by the back plate.
