       FIELD OF THE INVENTION 
       [0005]    The present invention belongs to the field of light sources and more particularly relates to a novel arrangement of light cells into a multi-dimensional light source arranged in a continuous manner, connected to a single power source and capable of unlimited configuration, capable of being controlled by wirelessly by means such as a mobile phone. 
       BACKGROUND OF THE INVENTION 
       [0006]    Light sources such as light emitting diodes (LEDs), Electroluminescence (EL), and organic light-emitting diodes (OLEDs) have paved the way for energy efficient lighting means. Oleg Vladimirovich Losev independently reported on the creation of an LED in 1927. Rubin Braunstein of the Radio Corporation of America reported on infrared emission from gallium arsenide (GaAs) and other semiconductor alloys in 1955. Braunstein observed infrared emission generated by simple diode structures using gallium antimonide (GaSb), GaAs, indium phosphide (InP), and silicon-germanium (SiGe) alloys at room temperature and at 77 K. 
         [0007]    In 1961, American experimenters Robert Biard and Gary Pittman working at Texas Instruments, found that GaAs emitted infrared radiation when electric current was applied and received the patent for the infrared LED. The first practical visible spectrum (red) LED was developed in 1962 by Nick Holonyak Jr., while working at General Electric Company. In 1976, T. P. Pearsall created the first high brightness, high efficiency LEDs for optical fiber telecommunications by inventing new semiconductor materials specifically adapted to optical fiber transmission wavelengths. 
         [0008]    The first commercial LEDs were commonly used as replacements for incandescent and neon indicator lamps, and in seven-segment displays, first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as TVs, radios, telephones, calculators, and even watches (see list of signal applications). These red LEDs were bright enough only for use as indicators, as the light output was not enough to illuminate an area. The invention and development of the high power white light LED led to use for illumination. 
         [0009]    Electroluminescence (EL) or the generation of light by the electrical excitation of light emitting phosphors has been around for many years. Electroluminescence was first observed in silicon carbide (SiC) by Captain Henry Joseph Round in 1907 who reported that a yellow light was produced when a current was passed through a silicon carbide detector. The first thin-film EL structures were fabricated in the late 1950s by Vlasenko and Popkov who observed that luminance increased markedly in EL devices when they used a thin film of Zinc Sulfide doped with Manganese (ZnS:Mn). Luminance was much higher in thin film EL (TFEL) devices than in those using powdered substances. Such devices however were still too unreliable for commercial use. 
         [0010]    Organic light-emitting diodes (OLEDs) are transparent when turned off the devices could even be installed as windows or skylights to mimic the feel of natural light after dark, or to serve as the ultimate inconspicuous flat-panel television. In 2006 scientists studying OLEDs made a critical leap from single-color displays to a highly efficient and long lived natural light source. 
         [0011]    Despite various improvements and progress in the field, some of the major obstacles that still exist to effective use of light sources such as LEDs, ELs and OLEDs are problems of configuration in novel sizes, shapes and patterns, problems in easy connectivity between different light segments, low light output, susceptibility to moisture, problems of easy installation without many peripherals, cost effective manufacture, maximum utilization of minimal power sources and short life. 
         [0012]    Accordingly, improvements are needed in the existing methods and structures that negate the above shortcomings in the existing systems. The relevant prior art methods, which will deal with light sources, are as follows.

An illumination system can emit electroluminescence light as well as reflect incident light received from an outside light source. A layer of phosphor is excited by a power source, and a reflective layer disposed on top of the phosphor layer reflects.

No. 5,976,613 describes a flexible thick film electroluminescent lamp and method of construction in which a single non-hygroscopic binder is used for all layers thereby reducing delamination as a result of temperature changes and the susceptibility to moisture. Thick film electroluminescent lamps comprise a phosphor between an optically transparent front electrode layer, and a back electrode layer, all covered by protective electrode layer. The two electrodes are generally planar layers, but may be grids of electrically conductive material disposed at right angles to each other so that the phosphor at selected grid coordinates can be excited.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0046]    As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of an invention that may be embodied in various and alternative forms. Therefore, specific functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and/or as a representative basis for teaching one skilled in the art to variously employ the present invention. 
         [0047]    The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of particular applications of the invention and their requirements. 
         [0048]    The present invention can be configured as follows: 
         [0049]    As disclosed in currently co-pending patent application Ser. No. 13/439,024, which is herein incorporated by reference; a primary unit of the present invention that is electrically powered, is called the mother cell, comprising of a large ring, non-conductive material rings, a small ring, non-conductive material, any efficient light source including but not limited to an LED or Electroluminescence (EL), copper springs, an electrical wire, and a background holding material such as adhesive tape. The mother cell is the first cell that connects to power source. A large ring in a mother cell has non-conductive material ring and on both sides of the large ring. The large ring in a particular mother cell acts as a connector to any side of another mother cell. A large ring thus passes electrical current to the light source via the electrical wire. A small ring acts as a connector to any other mother cell and has non-conductive material on one side of the small ring. The small ring passes electrical current to the light source via an electrical wire. The copper springs in the present invention improve electrical connectivity among the various sister cells, and provides flexibility by facilitating bending between sister cells so that they can be arranged in various configurations not restricted to a straight line and including a spherical or other configuration. 
         [0050]    This makes it possible to create diverse kinds of unconventional configurations to create a particular larger light pattern and further the light cell configuration need not be arranged on a conventional hard background surface but can be arranged on any flexible background material. 
         [0051]    The mother cell connects to an AC or DC electrical source. From the mother cell, electrical power is transferred to the remaining cells called sister cells when they are connected to the mother cell. Miniature transformers, designated as “booster cells” ensure electrical current transfer to the sister light cells that are situated away from the mother cell. 
         [0052]    The present invention aims to provide a “smart” light cell configuration wherein selective switching on or off or particular light cells among the continuous light cell arrangement is possible by wireless communication by the user. This is achieved by a software application present on a user&#39;s smart device that is in wireless communication with control modules provided on the light cells. 
         [0053]    Short range communication technologies such as Near Field Communication and Bluetooth protocol as known in prior art are used to control the switching on and switching off of sister light cells or booster cells or the mother cell remotely. 
         [0054]    According to a preferred embodiment of the present invention, each light cell (the mother cell and every sister cell) is provided with a control module further comprising of a Bluetooth module in wireless communication with software application present on a smart device and a logic module electrically connected to the Bluetooth module.

No. 13/439,024, wherein said light cell arrangement comprises of a plurality of sister cells and a mother cell. Each light cell, is provided with a control module comprising of a Bluetooth module that is electrically connected to a logic module. The logic module is further electrically connected to a light source such as an LED cell or electroluminescent EL cell or any other efficient light source. 
         [0056]    The smart device  19  may be a smart phone or a tablet PC or a mobile computing device. In the present embodiment, the smart device  19  is a smart mobile phone. The smart device  19  is wirelessly connected to the Bluetooth module  18  of sister cells  15 .  11  depicts the main power source which provides input power to mother cell  13 .  17  denotes booster cells. In alternate embodiments, specific sister cells may be designated as “booster cells” in order to boost the voltage to clusters of distant sister cells to compensate for any voltage drop as the current travel to cells away from the mother cell. DC-DC booster cells (boost convertor or step up convertor) as known in the art may be employed for this purpose. 
         [0057]    The smart device  19  transmits a wireless signal to the Bluetooth modules  18  of sister cells  15  so as to control the selected switching on or off of specific light cells to obtain a different illumination effect. 
         [0058]    In the current embodiment, the smart device is a smart phone. As depicted in  FIG. 2 , the smart device  19  has an app, wherein the continuous arrangement of the light cell assembly is depicted as a grid or matrix. A user can select specific light cells by touching their cell location as shown in the grid or arrangement displayed on the smart device screen. The user&#39;s touch events are interpreted as different commands and wirelessly communicated using a Bluetooth communication module residing on the smart device to the Bluetooth module on the respective light cells. 
         [0059]    The Bluetooth communication module present in the app is configured to transmit and receive wireless signals. In the present embodiment, this module may be configured as a Bluetooth communication module transmitting and receiving Bluetooth signals or a Wi-Fi network module transmitting and receiving Wi-Fi signals. 
         [0060]    The app is provided with functionalities such that specific user commands are generated based on type of user input. In one embodiment of the invention, the app conveys the address of the light cell and command to switch on or off the light cell.
