     FIELD OF THE INVENTION 
     The present invention is related to an intelligent interactive control system consisting of a control unit, and an interactive unit that is connected to or integrated with an electrical device to control electrical power and to program the use of power by the device to provide interactive lighting, and control appliances, office equipment, medical equipment and other electrical devices The interactive control system may further have actuator units that provide for information to be exchanged with the interactive devices in such a way that they can be made to operate according to a configurable way that may vary over time and according to the environment and power supply situation to save energy and increase safety. 
     BACKGROUND 
     A lot of effort has been channeled recently into developing new energy efficient equipment as a means to save energy and reduce the ecological impact mankind has on the environment. This effort has been paralleled by a constant increase in the price of energy that gives residential, industrial and even government users an incentive to reduce energy consumption and by doing so save money. 
     Among the several possibilities available, one that has been gaining momentum is replacing old technology lamps, appliances, office equipment, medical equipment and other electrical devices with new ones that offer similar performance and provide a substantial reduction in electricity consumption. As an example, recently developed light-emitting diode (LED) lamps are basically made from an array of semiconducting LED devices assembled together with other necessary electronic components to deliver similar performance as traditional lamps and at the same time allow the user to save a substantial amount of the energy. Because LED lamps need to have a lot of electronics built in the units, it is possible for the manufacturers to pack in additional control circuits at a very small incremental cost and offer additional features that may give them an edge on an increasingly competitive market and help customers to decide on the replacement for their particular product. Although the main incentive remains the energy savings, all favorable features, both those naturally inherent to the new technology and wherever the case, the additionally added functions add up to a number of advantages for the customers to consider when deciding whether or not to replace old lamps. 
     A simple list of features currently seen on the market are:
         1. Reduced power consumption.   2. Less heat production.   3. Ability to dim the light to any desired level.   4. Smaller size and weight allowing for new possible applications.   5. Better resistance to vibration and mechanical shock.   6. Increased reliability and life span.   7. Ability to operate within a brighter range of voltages and frequencies avoiding damage from improper use or fluctuations in the electric supply.   8. Ability to vary light color and brightness (temperature).   9. Other special features that may be available such as integrated motion sensors, remote control, etc.       

     Although this may appear to be an impressive array of advantages, the initial cost of the lamps remains a barrier preventing the rapid adoption of the new technology, and even more so when the user already has a high number of old units installed. 
     Many control units have been available to produce all sorts of light displays in commercial or residential environments. Mostly these units are used for a special purpose such as to highlight a particular object or area or for a specific event such as Christmas, New Year, or special commemorative days, for example. These units are normally made to order by expert technicians or in some cases mass produced by manufacturers for example for Christmas lights, sequential lights and so on. For home and office use, some companies offer sophisticated electronic switches that allow the user to switch on and off or dim the lights. These must be installed replacing the old traditional on/off switches and are normally considerably more expensive. Also some of these high end switches can interface to a remote control unit allowing the user to control all lights in a room or region with a remote control unit. Some units offer the possibility to program on and off times and simulate presence in the house as a means to increase user comfort or deter burglary. These units remain though as an add-on to the lamps and do not really integrate to the lamps or alter them in a substantial way. The lamps remain basically just simple devices that can only be switched on or off. In the event that the external controller is bypassed, the lamps will simply operate as normal lamps reducing the possible applications of the controller. Other newer designs for appliances, office equipment and medical equipment also provide reduced power consumption and other features that may be optimized even further using the intelligent interactive controls of the present invention. 
     SUMMARY OF THE INVENTION 
     A new interactive control system consisting of a control unit, remote interactive units and programmable actuator units is proposed. This system allows information to be exchanged between the control unit, programmable actuator and the remote interactive units in such a way that lights, appliances, office equipment, medical equipment and other electrical devices can be made to operate according to a configurable way that may vary both over time and according to the environment and that controls the supply and power output to save energy and increase safety. 
     The system can operate with only interactive units and/or programmable actuators in a manual configuration mode or if one or more controllers are used in an enhanced mode offering additional functionalities. The system can operate autonomously and does not require constant user intervention. Users can implement multiple configuration schemes suitable for their needs and comfort. Different configurations can be made to maximize savings, comfort or safety taking into account multiple factors such as the season of the calendar year, the time of day, the cost of electricity at peak hours and off peak hours, and other conditions based upon operational settings or requirements. The system can be configured to automatically switch between different configurations according to external factors such as a power failure, a burglary alarm, or a fire alarm, for example. 
     The remote interactive units have embedded control circuitry used in implementing the technology of the present invention. This embedded control circuitry causes no significant cost increase to the lamps, appliances, office equipment, medical equipment or other electrical devices and if the user so wishes the electrical device can still be used in a normal stand-alone mode without any communication with a controller or actuator so that if no configuration setting program is made the lamps, appliances, office equipment and medical equipment simply behave as normal devices. The added embedded circuitry for a lamp may be installed, for example, in housings suitable for replacement in incandescent, fluorescent, halogen, LED or other lighting configurations. The current invention creates a fundamental improvement over the way the devices can be controlled and deployed and therefore reduces the resistance of users to replace their old lamps or appliances with new ones. The new features provide new ways for users to benefit from the interactive units and it is expected that even users that already have replaced old lamps with newer more efficient bulbs may decide to upgrade to new ones using the proposed technology to benefit from the new possibilities offered. 
     One of the objects of the present invention is the control of multiple interactive units individually or collectively. This can be used for practical purposes for example to switch off all lamps, computers, copiers, and other equipment in an office or building after work hours from a single point or from a computer, smartphone, tablet or other digital device. It can also be used for special purposes for example to set up special effects using an interactive unit integrated with a lighting system to produce moving or static patterns or even text messages on a tall building façade for advertising, Christmas or other special occasions. 
     An object of the invention is the reduction or increase in lamp power output (luminosity) according to a custom pattern or program to improve power savings (for example varying power according to daytime or night time in an office or reducing power during lunch time). 
     Another object of the invention is the ability to control the interactive units without the necessity of traditional physical switches that interrupt the electrical current to the units. In this way physical switches can be removed altogether from the building installation reducing installation costs and construction time, improving aesthetics of the rooms and facilitating room rearrangements at a later time. The interactive units can be relocated to other places simply by moving them without the need to reroute wires. Programmable interactive control units can be easily placed at any convenient location and be programmed to activate, dim, deactivate or perform other operations on one or more lamps of an interactive unit lighting system or operation of an appliance according to user convenience. 
     A further object of the invention is the ability to produce random yet consistent illumination patterns in a building to simulate human presence as a means to deter burglary. The interactive lighting system units may be preprogrammed or be controlled remotely over the internet from anywhere using a computer or smart phone. Using this feature, in conjunction with a web cam, a user will be able for example to check the status of pets or presence of intruders in his home anytime, switching on lights at night if necessary only during the time he needs to watch the images. 
     A still further object of the invention is in case of power loss if an emergency backup generator and/or a no break battery operated system is available the system automatically adjusts power consumption switching off all non-essential lamps and/or dimming the ones switched on according to a previous programmable configuration or based on the time of day to manage the situation as well as possible. This allows the home, office or factory where the system is installed to easily implement an emergency lighting system without the need of making big and costly modifications to the electrical installation. Lamps with batteries used for emergency illumination can also be fitted with the interactive technology allowing them to communicate with the controller so that critical information such as battery charge and quality of the lighting system, such as through hours of usage can be easily made available. 
     A still further object of the invention is the configuration of special illumination profiles for seasons of the year, special occasions or emergencies such as summer/winter time, anniversaries, Christmas, New Year as well as fire, burglary detected, power fluctuations, or other conditions or events. 
     The present invention can further control power consumption and produce consumption reports indicating current and projected consumption over a period of time. The present invention further automatically detects all interactive lighting system units connected within an area and reports degraded luminosity or defective components that need replacement. 
     A still further benefit of the interactive lighting system units is the ability for a user to easily program intended time for each unit to be lit after triggered manually or by a presence sensor. 
     The interactive control system further opens the possibility for new business models involving lighting and electrical systems. For example, a company could purchase the interactive control system for a customer or other third party, program the interactive units according to the customer wishes and necessity and install them at an office or factory. Instead of purchasing the interactive units immediately the final customer could agree with the supplying company specific conditions to receive the units such as signing a long term lease contract or pay for the installation in installments over a period of time. The monthly amount due could be calculated according to actual power savings or at a fixed rate according to agreement between the company and the customer that could include a maintenance fee and warranty for the interactive units. Such arrangements would assure the customer an immediate positive result in savings without the need of initial investment and without the risk of loss in case the failure of new interactive light units too soon or if they do not save as much energy as advertised. The company owning the interactive units would have a profitable contract and may receive a bonus based on the customer&#39;s power savings. In case the customer fails to pay the bill the company would be able to dim the interactive light units or even switch them off remotely or otherwise reduce or prevent the operational functions or performance of the interactive units. To prevent the customer from just switching off the controller, the interactive units could be programmed so that if they lose communication with the controller for an extended period of time (due to the customer disabling the controller) they would switch off or dim to a low enough level to be unsuitable for illumination of the customer&#39;s premises during work hours but still be safe for humans to be present inside the building. Once the customer paid the bill a remote command would re-enable the interactive light units to operate normally. 
     The interactive control system could further manage the operational functions of interactive units integrated with appliances, office and medical equipment and other electrical devices to for example reduce power output during off peak hours or shut down unnecessary systems overnight or during power fluctuations or outages to protect them from power surges. The devices may be integrated with the interactive technology as described herein or control interface units may be used to provide the communication and control to adapt the devices to be controlled within the interactive control system. 
     The present invention is related to an interactive control system comprising a control unit; an electrical device; at least one interactive unit having embedded control circuitry connected to the electrical device; and wherein the control unit establishes communication with the embedded control circuitry of the at least one interactive unit to control electrical power to the electric device. The control unit of the interactive control system may communicate with the at least one interactive unit through electrical power lines within a building and/or through wireless communication. The electrical device of the interactive control system may be one of a lighting system, an appliance, a piece of office equipment or a medical device. The remote interactive unit with embedded control circuitry of the interactive control system may further comprise an address number and/or group number and the electrical device group number that is dependent on the operational functionality of the electrical device within a programmable network. The interactive unit having embedded control circuitry within the programmable network may be displayed graphically on a display screen of a digital device that provides for the electrical device to be manually configured by a user through a series of menus and buttons to control the electrical device according to the user&#39;s desire. The control unit of the interactive control system may be a programmable actuator that replaces traditional physical electrical switches to control the electrical device within the programmable network. The interactive control system may further comprise a plurality of electrical devices each connected to at least one interactive unit having embedded control circuitry; and the control unit may operationally control the plurality of electrical devices within the programmable network simultaneously. The control unit may simultaneously reduce power output to the plurality of electrical devices within the programmable network for non-payment of fees. The plurality of electrical devices of the interactive control system may be a plurality of LED lamps and the control unit may simultaneously command one or more of the plurality of LED lamps to sequentially turn on and off the LED lamps based on a display pattern. The control unit may implement configurable illumination plans that vary according to the season of the year and time of the day to maximize energy savings, user comfort and safety. The programmable actuator of the interactive control system may be automatically configured by a series of commands issued by the control unit running specially designed interactive software. 
     The present invention is further related to an intelligent interactive control system that comprises at least one interactive unit having interactive control circuitry; an actuator that communicates with the at least one interactive unit; a control unit that communicates with the actuator; and wherein the control unit implements advanced control strategies that enable the at least one interactive unit to operate under programmed electrical conditions. The intelligent interactive control system may further comprise a management system that allows a third party to fully utilize the intelligent interactive control system while the management system retains operational control of the system to, if necessary ensure payment by overriding users commands and settings to reduce performance or disable at least one interactive unit within the system. The intelligent interactive control system may further comprise configurable illumination plans that vary according to one of at least the season of the year, the time of the day, the available power in the case of a power outage to maximize energy savings, user comfort, and safety. The interactive unit of the intelligent interactive control system may be at least one control interface unit that communicates with an electrical device through an AC mains power distribution network to receive commands from the control unit and/or actuator. 
     The present invention is further related to a method of interactively controlling an electrical device comprising the steps of integrating an electrical device with embedded interactive control circuitry; communicating with the electrical device with the embedded interactive control circuitry using an actuator; communicating with the actuator using a control unit; and controlling the operation of the electrical device with embedded interactive control circuitry with the control unit based on one of least the environment, the season of the year, the time of day or monetary considerations. The method of interactively controlling an electrical device may further comprise the steps of controlling a plurality of electrical devices with embedded interactive control circuitry within an interactive network with each of the plurality of electrical devices having at least an address and at least a group number. The method of interactively controlling an electrical device may further comprise the steps of installing the interactive network at a third party; managing the interactive network system for the third party; allowing the third party to fully utilize the interactive network while retaining operational control; overriding user commands and settings to reduce performance or disable electrical devices within the interactive network due to non-payment. The method of interactively controlling an electrical device may further comprise the step of configuring illumination plans for the interactive network that vary according to one of at least the season of the year, the time of day, the available power due to a power outage to maximize energy savings, user comfort, and safety.

     DETAILED DESCRIPTION OF THE INVENTION 
     The controller or control unit  10  as shown in  FIG. 1 , is basically a custom computer system, containing an electronic mother board  1  with a microprocessor  2  and all necessary electronics such as memory, input output interfaces, sensors, and other components. It operates with normal AC power  3  or battery power and has internet connections that may be using network cables  4  and/or wireless communication  5 . It can communicate with the remote interactive units and actuator units using the alternating current (AC) electrical power lines  3  within one or more buildings, internet network cables  4 , wireless communications  5  or a FDM (frequency division multiplex) wireless interface  11 . It is constructed to be packed in a small box similar in size and shape to a decoder used in cable TV operation. The box may have a slot for a smart customer card  6  containing a memory chip to be inserted allowing for the identification of a customer and/or an interface to USB memory sticks  7  enabling information to be easily inserted into the system. It also has indicative lights  8  for power, communication and general alarm to enable the user to easily get critical information and react accordingly. 
     General purpose analog and digital interfaces  9  are available in the controller  10  to allow it to interface to other systems that may already be installed at the site or that may be installed in the future. These systems can also be connected to a control interface unit  80  that communicates with the controller  10  through the main power lines, internet or wireless communication interfaces. The control interface unit  80  provides an interface to use the system for appliances, office and medical equipment and other electrical devices within the interactive system through the electrical power lines or AC mains  35 . The control interface unit  80  may further allow the controller  10  to collect a wide variety of information and be able to take appropriate action depending on ordinary external circumstances such as availability of natural ambient light, reported by one or more light, temperature or other sensors, and also respond to extraordinary or emergency situations such as fire, burglary detection, power fluctuations, emergency power being provided by a generator/no break in operation, or other environmental conditions. 
     Specific software written to run on a computer or smart phone is used to communicate with the controller  10  allowing advanced features to be accessible by the user such as the ability to graphically display information, audit and change configuration information, program a group of interactive light units to behave as one, program patterns, or perform other operations using the control unit  10 . To improve safety, the control unit  10  has an access system requiring a user name and password to allow, restrict or limit access to certain functions. The users have different categories and privileges in a similar way to modern computers and the system may report any failed login attempt to an administrator and other users through a wired or wireless transmission and/or through data logs accessible on the control unit after login by an authorized user. Additional safety measures are also in place such as data encryption, a configurable time delay until the next possible login attempt after each unsuccessful login attempt to prevent brute force attacks, an alarm light that will be lit in a easily visible location at the control unit  10  in case any unsuccessful login attempt has occurred until it is acknowledged and cleared by a route level administrator or user with this privilege. 
     The control unit  10  comes from the factory with a route administrator user preconfigured with a default password. Upon first use this administrator user will be used to configure additional users of different categories with each category having their particular privileges and access to different functions of the system. The route administrator should only be used by qualified personnel and preferably only for system configuration, upgrades and changes. For safety it is recommended that only one person has access to the route administrator user and the factory default route user password be changed as soon as possible for security. 
     The interactive light units  20  as shown in different embodiments in  FIGS. 2A and 2B  are manufactured by installing circuitry to an LED lamp. The interactive light unit  20  may be installed in different housings to replace conventional lamps such as a fluorescent type housing  21  as shown in  FIG. 2A  and an incandescent type housing  22  as shown in  FIG. 2B . At the time of manufacture, a small interactive microcontroller and necessary peripheral circuitry are installed to receive commands from the control unit  10  and/or actuator units  50  and implement all intended action on the interactive light unit  20  such as switch it on and off, dim, vary color or light temperature, or perform other features. The interactive circuitry can be implemented using electronic components  24  that are assembled in a circuit board  26  in a standard manufacturing process. The interactive circuit board  26  may be independent from the circuitry containing the LED devices  25  as shown in  FIG. 2B  or may be configured on the same circuitry platform  27  containing the LED devices  25  that produce the light. In further embodiments, if space requirements or production volumes justify, all the necessary circuits may also be integrated into a custom interactive circuitry chip  28  as shown in  FIG. 2A . 
     The additional embedded interactive circuitry integrated into the LED lamp interfaces with the existing LED circuitry in such a way to provide the intended degree of control. A block diagram of an embodiment of the interactive circuitry  30  capable of implementing the required functions is shown in  FIG. 3 . A unique address number  31  for each device is set at the time of manufacture or is programmed using the controller  10  to provide for the controller to identify each Interactive Light Unit (ILU)  20  and to communicate with a number of devices simultaneously and/or issue commands to specific units. Since the number of bits necessary to identify the number of groups  32  of lamps on a particular installation will be much smaller than the number of bits allocated to the lamp addresses  31 , once the units are detected and identified they are assigned to groups consisting of one or more lamps. The system control  33  stores each address number  31  with the group numbers  32  of all groups to which the unit has been assigned and responds to commands issued to these groups. These commands can arrive and be sent through the AC mains  35 . Arriving commands once filtered from the power supply are decoded by the communication interface  49 . The communication interface  49  also can receive and transmit commands through the internet  34  (either by cable  4  or wireless transmission  5 ) or through a wireless FDM interface  11 . 
     The AC power supply with appropriate line filters  36  and/or a battery  41  supplies a power supply  39  to accommodate the interactive and LED circuits. The system control  33  receives commands from a controller  10  or actuator units  50  through the communication interface  49 . If a command has the address of the specific ILU  20 , the system control  33  processes and directs the command to the embedded interactive control circuit  38  that interfaces to the LED control circuitry  40  to implement the appropriate action. A simple LED lamp with only on/off control is enhanced with circuits to control intensity (brightness)  42 , color (temperature)  44  and a timer  46  may be added to allow those functionalities. Adjustments to these settings and functions are fed to the LED drivers  48  to modify the illumination characteristics of the array of LED devices  25  on the addressed interactive light unit  20 . 
     Actuators units  50 , as shown in  FIGS. 4A and 4B , are designed to replace the traditional on/off switches or dimmers that control traditional lamps. They can be constructed to be wall-mounted  52  or portable  54 . They are made using a general purpose display with touch screen capability  56 . An electronic board  58  with all necessary circuits provides the capability to communicate with the control unit  10  and interactive light units  20  over the AC mains  35 , internet  34  or FDM  11 . The wall mounted version  52  has wires  60  to be connected to the AC mains  35  and the portable version  54  is fitted with a rechargeable battery  62  and a charger inlet  64  that can be designed to accept a standard USB charger or AC power. 
     The actuator unit  50  displays an icon for each interactive light unit or group of interactive light units  20  that is assigned within the interactive control system  60 . A simple icon  66  is used to indicate standard on/off operation. When one interactive light unit  20  or group of interactive light units is switched on the icon is highlighted  68 . Depending on the configuration and LED circuitry capability other icons can be displayed such as a dimmer bar  70  that depending on configuration can be associated with a numeric indication of the selected luminosity level  72 . In the application of a timer operation, the timer icon displays the remaining time by means of a pie chart  74  and/or number  76 . Also a reducing bar  78  or other graphics with various functionality can be configured. 
     Fully compatible and interchangeable monochromatic and color versions of actuator units  50  may have different display sizes to display a higher or smaller number of controls that may be offered. Variability in features and functions allows the user or customer to freely select what type of actuator  50  to install in each specific location to use as remote controls choosing between cheaper or more sophisticated versions depending on the needs and budget. Actuator units  50  do not control the interactive light units  20  by means of physically changing their electrical connection to the AC mains  35  or interrupting the circuit such as in the operation of a traditional switch. Instead the actuator  50  simply sends a command to the control circuitry telling a specific interactive light unit  20  or group of interactive light units to perform the required operation and the selected unit(s) implement the command. The interactive light units  20  remain connected to the AC mains  35  at all times. That allows the system to be easily reconfigured without the need to redirect wires and also allows the user to assign an interactive light unit or group of interactive light units  20  to be controlled by several actuators  50  in whatever manner is most convenient. To implement such a control scheme in traditional installations is very difficult because the number of return wires and poles of the switches necessary to implement the circuit grows very quickly beyond practical constraints. 
     The actuators  50  can be made in several different configurations. The actuators  50  can be constructed to be physically mounted to a wall or fixed at any specific location for convenience and may be permanently connected to the AC mains  35  for its power supply or as an independent device that has its own rechargeable battery that the user can place anywhere that is convenient or that can be carried by the user as he moves around. The operations of the actuator unit  50  may further be implemented on any mobile or digital device through a software application such as on a smartphone, iPod, iPad, tablet computer, laptop or other device that can be used as a processing unit, a display unit, and as a service offered via the World Wide Web. 
     The control interface units  80  as shown in  FIG. 5  are units intended to expand the operational functions and possibilities of the system. The control interface units  80  operate as interfaces so that devices that do not have embedded control circuitry can be integrated to the network and be controlled by the control unit  10  and/or actuator unit  50 . These devices may be any electrical device such as electrical appliances, computers, copiers, monitors, other office equipment and medical devices that can be added to the system and be controlled to the necessary degree. The control interface units  80  are composed of a board  82  with the same basic electrical circuits  84  to enable information exchange used in the interactive light unit  20 , controller  10  and/or actuator  50  and additional input/output digital and analog interfaces  86  to collect information and control the intended device. Such devices  80  could be for example luminosity detectors, sound producing units to be used as audible alarms, power usage indicators, a general purpose switch to allow the system to switch on and off any device for example to protect it in case of power fluctuations or cope with power limitations imposed by the available emergency generator during a power outage. The control interface units  80  allow the system to manage a wide variety of devices once the necessary information is configured by the user into the software. The control interface units  80  are connected to the AC mains  35  as shown in  FIG. 6  and communicate with the controller  10 , appliances or other devices through this connection. The control interface units  80  can also communicate with the control unit  10 , appliances or other electrical devices using wireless communication. 
     Control interface units  80  can also be integrated into one custom chip as previously described for the interactive light units  20  and be integrated into any of the appliances such as an air conditioner  88 , washing machine  90 , television  92 , dishwasher  94  and other devices. Control interface units  80  or the interactive appliances fitted with the chip are manageable using the control unit  10  in the same way as an interactive lighting system  20 . The user can then configure special utilization plans for these interactive units, for example to reduce the power consumption of the air conditioning during peak hours or to program the wash cycle for a more convenient time, or use an actuator unit software application on a mobile phone to see if a particular device or lighting system has been left on at home and perform many more operations. In this way starting with the interactive light units  20 , the user can build up a very sophisticated interactive control system  60  for all lighting, electric appliances, office equipment or medical devices in the home or office by adding on new interactive devices at once or slowly one at a time as old units are replaced with new interactive ones fitted with the technology. 
     Traditional lamp switches and circuit breakers can also be used for safety and as a means to completely switch off one or more interactive units according to best engineering practices for electrical installations. Switching off the interactive light units  20 , actuators  50  and control interface units  80  or other interactive devices does not affect the operation of the system. All configured information is stored in persistent memory so that it will not be lost in case of power failure or if the interactive units are switched off using normal switches or circuit breakers. When power is restored or the interactive units are switched on again they resume normal operation such as going back to their last state prior to loss of power. Each individual system (controller  10 , interactive light unit  20 , actuator  50  and control interface units  80 ) has its unique identification number  31  by means of a one-time programmable number burned at the factory or programmed using the controller  10 . This identification  31  may be an alphanumeric code that is reported to the control unit  10  and stored in a table. Every time the control unit  10  needs to communicate with an individual unit in the system (slave controller  12 , interactive light unit  20 , actuator  50 , control interface unit  80  or other interactive device) it will consult this table. Each unit also has its own type number indicator  37  that allows the controller  10  to properly identify each unit and the software to retrieve unit characteristics such as physical shape, power consumption, available commands, and other operational features and specifications of a particular device. The control unit  10  may communicate with other units in the system using preferably a small amplitude high frequency signal over the mains  35 , or alternatively using wireless transmissions such as WIFI, Bluetooth, FDM or infrared. Appropriate filters and bypasses may be installed at circuit breaker boxes to allow access to all circuits. 
     An embodiment of operational commands for the controller  10  is shown in  FIG. 7 . These commands  100  include selection of a control group  102  or a single unit  104 , powering a unit on  106  or powering a unit off  108 , setting a timer  110  to perform an operation at a later time or for a certain period of time, setting an event  112  that may set text or a pattern  116  of, for example the interactive light units  20  to display an advertisement, a celebration of the event or holiday, a warning or other information or artistic design. Additional information can be preset or programmed into the controller  10 , interactive light unit  20 , actuator  50  or control interface unit  80  using communication software developed for the interactive control system  60  on a computer, smart phone, tablet or other digital device. A program  130  developed on, for example an actuator  50 , and stored  140  may be reviewed by the controller  132 , edited by the controller  134 , implemented by the controller  136 , or overridden by the controller  138 . Particularly in an emergency event response  150 , a preset program on a controller  10 , an interactive light unit  20 , an actuator  50 , a control interface unit  80 , or any local control  152  may all be overridden to put the system in a power management mode  154  and for example reduce the power output  122  and shut down unnecessary electrical systems. The ability to develop preset programs on any unit or group of interactive units within a system  60  allows for the system  60  to implement advanced features to enhance operational control and efficiency of energy use within the system. These features may include the following: 
     Configure groups. One or more group numbers can be assigned to each individual interactive unit so that they are able to respond immediately to a single command from the controller  10  if any one of the groups it belongs to is addressed. 
     Timer mode. Interactive light units  20 , control interface units  80  and other interactive devices can be configured to operate in timer mode. A user defined time for each individual unit or group of units can be set allowing light units  20  and interactive devices to switch on or off automatically after the preconfigured time has elapsed. 
     Reprogram actuator. The user may be allowed to reprogram the actuator  50  so that one actuator  50  can be used to switch on and off or dim a specific interactive unit or group of interactive units. 
     Preprogram Interactive Units. Interactive units can be programmed to respond only to a specific actuator  50  or set of actuators (or to ignore commands from any actuator and remain lit at all times) by any user having configuration privileges and will from then on only respond to the appropriate actuators  50 . Only users with equal or higher priority can override configuration commands, none being higher than the route administrator. 
     Special illumination plans. Illumination plans can be implemented to accommodate for variations in electricity cost according to seasons of the year, summer/winter time or wet and dry seasons to maximize savings and user comfort. 
     Special occasion plans. Similarly to the previous item, special illumination plans can be programmed for special occasions such as anniversaries, Christmas, New Year or festive days. Such plans could enable home users to dim or blink a set of interactive light units  20  to create a special atmosphere and offices to use the light units  20  in their façade to display static or moving patterns or even text messages depending on specific size and shape of the building. As shown in  FIG. 8 , a special illumination plan for a building  160  may sequence a series of interactive light units  20  indicated as A-F turning each on and off consecutively or randomly turn lights on and off indicated as X-Z in each room of the building  160  to create an unusually eye-catching effect. In further embodiments as shown in  FIG. 9 , a group of interactive light units  20  within a building  170  may be turned on to display a text message such as Hi or an advertisement, Christmas tree or company logo on the façade of the building  170 . 
     Preconfigured emergency illumination plan. In case of power loss if an emergency backup generator and/or a no break battery operated system is available the controller  10  will send a single command and quickly switch off all non-essential interactive units and/or dim those that are on to reduce power usage and manage the situation as well as possible according to the available emergency power and time of the day and year. That allows the home, office or factory where the system is installed to easily implement an intelligent emergency light system without the need of making big and costly modifications to the electrical installation and wiring. 
     Other emergency events. Similarly to the previous item, emergency plans can be programmed for other critical events such as fire, non-authorized entry or burglary detection, power fluctuations, or other events. Such a plan could for example make light units near exits blink and/or light to illuminate a path leading to an exit. The light units may be located at the floor or ceiling to illuminate and blink in a sequential way to facilitate evacuation in case of fire or switch on all light units at maximum illumination and blink selected external light units and, if available, trigger an audible alarm to attract external attention and help in case of burglary detection. 
     Configuration and Operation of the Units and System: 
     The interactive units or control interface units  80  are able to operate either as stand-alone or in intelligent mode. Unless properly configured at installation or at a later time, any interactive unit will simply behave in normal stand-alone mode, switching on and off when power is applied or removed and operating as any other traditional lamp, appliance or equipment. This allows the factory to reduce production costs by standardizing production at the factory and to avoid unnecessary changes or additional configurations at the time of manufacture. The user can also use purchased interactive devices in a simple traditional installation and decide only at a later time to configure a system  60  and if he so wishes to introduce other devices into it to be able to use the advanced features and benefits of his already available interactive light units  20 , control interface units  80  and other interactive devices. 
     The configuration of the system  60  is designed to be as easy and straight forward as possible. Upon being connected to the AC power, interactive units will enter stand-alone mode and simply behave as normal lamps, appliances or electrical equipment switching on and off according to available AC power  35  until they receive a command. Actuator units  50  when first turned on or connected to the AC power  35  will enter configuration mode, display the configuration icon and wait for user confirmation of manual configuration or for received commands from the Control Unit  10 . Once an actuator  50  has been configured and has been assigned to at least one interactive unit, it will no longer display the configuration screen and when AC power  35  is cycled, it will instead display the control screen  56  showing all configured control icons. 
     Once the user confirms the manual configuration, the actuator  50  will send an information request command informing its own address. That will cause all connected interactive light units  20 , control interface units  80  and/or interactive appliances and electrical equipment receiving the command to respond informing their type identification  37  and their address  31 . In an embodiment, each interactive unit receiving the information request command will first wait a random number of power cycles and then transmit and wait for acknowledgement. If the acknowledgement is not received it will wait again and then transmit its information until the ongoing communication is completed. Alternatively, other communication protocols may be implemented dependent upon the configuration of the interactive device. 
     Once the actuator unit  50  receives the information from an interactive light unit  20  or other interactive device it will send an acknowledgement message with the received address of the interactive light unit  20  or device that sent the message. This will cause the corresponding interactive unit to stop transmitting its address until receiving another command. In this way, the request information procedure will continue until each of the interactive units have been addressed and acknowledged completing the procedure. 
     The actuator  50  will then prepare a list with each of the interactive unit addresses that are available within its transmission area, automatically create a group and command the first interactive unit on the list or for example the unit in closest proximity to the actuator  50  to start blinking or to perform another test sequence to confirm operational function and communication with the actuator. During the test operational sequence as shown in  FIG. 10 , the actuator  50  will display icons or other indicators on an interactive display window  200  that presents all available interactive units to the user. The user will then see if he wants a particular interactive unit to be controlled by that actuator  50  and if so confirm the selection of the interactive unit by selecting the unit icon, menu item, or other indicator and for example highlighting it, or dragging and dropping it into the selected interactive unit display  204 . A configuration window  206  will be displayed offering the possibility of power on or off  208 , setting a timer  210 , setting a dimmer control  212 , and/or entering an emergency power setting  214  or other operational features. The emergency power setting  214  provides for the user to configure the interactive light unit  20  or interactive device to remain on as essential lighting or equipment such as maintaining power to a medical device such as an oxygen machine in the event of a power outage. The operational features are dependent on the possibilities that a particular interactive unit offers according to its type identification  37  so the user can choose what operational functions for the interactive device he wants. In case of timer operation  210  he informs the number of hours, minutes or seconds or at what time the interactive light unit  20  will be lit or the time to turn on an interactive appliance or other electrical unit once commanded. 
     The user will then be able to select other interactive light units  20  and interactive devices for group operation by touching the group icon or dragging the interactive unit icon into the group display window  216  and confirming the acknowledgement of other interactive units into the current group. Only compatible interactive units that offer the same control options selected for a specific group will be accepted, and the actuator  50  will automatically skip incompatible ones. Once the user is satisfied he presses the enter icon  218  and the window may close and/or direct the user to the available interactive units display  202 . A help icon  222  may also be provided to assist the user in system commands and operation. 
     If the user does not want to include the currently blinking interactive light unit  20  or interactive device, he selects the next icon and the actuator  50  stops signaling the current interactive unit and starts blinking or sequence testing the next one. This operation will be repeated until all interactive units have been skipped or confirmed and configured into a group that will have at least one interactive unit and up to all units present. 
     After the first group is created, the user can create additional groups by touching the new group icon  220  in the group display window  216 . The user can create as many groups as he wants (limited only by the available actuator memory) with at least one interactive unit in each group and additionally any combination of the remaining available units. If the user makes a mistake or wishes to change a group or configuration, he can navigate through the group display window  216  to identify the interactive unit to include or remove from a group by running a test or sequence and checking which unit is blinking or for example producing an audible sound for identification and confirming the operation. Groups may also be edited to change the control options or operational features and if these changes remove the compatibility of an interactive unit within the group, the actuator will automatically remove interactive units that do not offer the newly selected control option from that group. 
     Using the actuator  50  touch screen in a first embodiment, the user may change the configuration of interactive unit at any time by accessing the configuration window  206 . The configuration window  206  may be accessed by for example touching anywhere on the screen and holding for 10 seconds (or a configurable time) and then tapping on the configuration icon that will be displayed on a different spot than where he initially touched. The interactive display window  200  will be displayed and the interactive units assigned to the first group will start to blink or produce an audible sound. Once the configuration changes are completed the actuator  50  will display the interactive display window  200  with the newly configured group of interactive units highlighted. 
     In the simplest possible case, the system  60  will be composed of just one interactive unit and one actuator. In this case once the user completes the configuration procedure, the actuator will display a single icon for that particular interactive unit that will be controlled only at that point. If the user wants the functionality of additional groups with different control options and configurations for that single interactive unit may be implemented. For example timer operation and dimmer controls that operate based on a special event setting. For these new configurations multiple icons will be displayed in the interactive display window  200 . The user will be able to select any icon at any time for any interactive unit and the current selected control option will override the previous one. 
     If a second interactive unit is available the user will have the choice of including both interactive units into one group or creating two independent groups. He can also create additional groups with different control options as described previously. If a second actuator  50  is introduced, it will be configured following the same procedure as described above. If an interactive unit or group of interactive units is configured into two or more actuators, it will be possible to control the units from any one of the actuators  50  where it is configured. In that case the user will be able to dim or switch interactive units on and off from multiple locations. In case of timer operations, a different time may be assigned to the same interactive unit or group of interactive units for every actuator giving the user the flexibility to alter their behavior depending on the geography of the room and his convenience. 
     The actuator  50  will create one icon for each group that the user configures. If there are too many icons to display in the available screen area, icons will be moved into additional pages that can be accessed by swiping the screen. The user can organize the icons in any order he finds convenient in multiple pages that do not need to be full and can have as little as one icon within a page or display. That may be a desirable thing to do for example configuring pages for each room or area in a house or office in a portable actuator unit  54  the user wants to use as remote control. 
     The same is also possible for wall mounted actuator units  52 , however, for practical reasons it is recommended that wall mounted actuators  52  be configured with as few pages as possible, preferably one because the actuator  52  is associated with the interactive light units  20 , or interactive appliances, office equipment or medical equipment within a room, area or location. In further embodiments, the actuators  50  can have any size screen or the actuator specially designed interactive software application can be integrated on a computer platform, mobile phone, tablet or other digital device and be displayed on a large screen computer monitor to accommodate buildings and areas having numerous interactive units each with icons or indicators within the screen. Additional wall mounted actuators  52  may also be incorporated for very large rooms or areas. 
     The system can be scaled up to any arbitrary number of interactive units, actuators  50 , and other interactive devices. If a large number of interactive units and actuator units  50  are installed, one or more control interface units  80  may be required and if the user wants to access special functionalities or use advanced control strategies, one or more control units  10  may be required to assist the user in maintaining and properly accessing all devices within the system. 
     Control units  10  provide more flexibility for the system by creating the possibility of multiple layers of commands. The control unit  10  can assign interactive units to a group defined by users with different priorities. For example, the route administrator possesses the highest priority, followed by administrators, users and guests. Guests do not have access to configurations and can only issue commands using objects that have already been configured such as activating a special illumination plan and/or recover reports such as on the current and projected power consumptions, list of defective units that need replacement, or other statistics on operational functions. Users at other levels can issue commands, collect reports and also setup configurations such as create a new group of interactive units, assign the group to one or more actuators  50 , create a special illumination plan, configure a control interface unit  80 , and perform other higher level functions within the system  60 . Access to the system  60  for users may be configured with a login name and password with all commands and changes logged indicating the name of the responsible user and the time the event happened. The log file can be audited later by an administrator or route administrator. 
     Users and administrators can create multiple configuration schemes suitable for their needs and comfort. Different configurations can be made to maximize savings, comfort or safety taking into account multiple factors such as the season of the year, time of the day, electricity cost at peak hour and off peak hour, and other environmental and location specific functions to optimize system performance. The system  60  can be configured to automatically switch between different configurations according to external factors such as power failure, burglary alarm, fire alarm, ambient temperature or other fault or programmed events. 
     A user can only apply changes to configurations created by users of the same level or below so no user can change a configuration created by the route user. This can be useful to prevent undesired changes to the system  60  done by accident or on purpose. This hierarchy of users with the highest level being the route administrator provides a platform that can also be used as a means to establish a business. For example, a company can purchase all interactive units and system components and set up and install an interactive system for another company. The receiving company is given levels of access only at a regular administrator level, user level and guest level but not access to the route administrator level. The company owning the interactive system  60  can then setup a management system to manage the configuration settings for the system. This control could be used to set all interactive light units  20  into for example a timed mode so that they automatically dim to 80% of the maximum luminosity after a period of time (for example 2 weeks or 1 month) and keep dimming down until they reach a value that no longer can provide adequate light for work but is still safe for human presence in the building. If the customer keeps paying the required fees in a timely manner such as on a monthly basis, an automatic reset command is sent over the internet before the time elapses, resetting the counter and keeping the interactive light units  20  operating at up to maximum luminosity and the system functioning properly. System safeguards will prevent the customer from disrupting the preset program such as if the customer disconnects the control unit, the interactive light units  20  will no longer be able to receive the time reset command and will dim after the configured period of time elapses. Because this configuration was set up by the route administrator and the company receiving the interactive control system  60  does not have access to this level the configuration cannot be changed. Any failed attempt to log in as route administrator can be made to generate a message to the owner company denouncing any attempt of tampering. 
     In this way a company can enter a business of leasing interactive systems  60  and share with the company receiving the system  60  the financial result coming from the power savings. The company receiving the system  60  is also benefited by being able to replace all its lighting systems, appliances, office and medical equipment without the need to invest money upfront and basically pay for the fees with the savings it has already made. At the same time it can also benefit from several additional functionalities that can be made available through the control unit  10 . The owner company can even create different packages depending on what services are allowed or charge separately for these services. Many other possible agreements can be made. 
     Once a control unit  10  is plugged into the system  60 , it assumes command of the AC power distribution network  35  under its supervision. It inquires for all actuators  50 , interactive units and control interface units  80  and produces a list of units with corresponding configuration information already present on the system  60 . Further configuration can be made and be sent to any unit amending or replacing manual configuration that had been previously done. Once the list is completed the control unit  10  will cyclically poll each actuator  50  based on adequate polling routines to optimize communication within the system  60 . The user will be able to place all detected interactive light units  20 , interactive devices, actuators  50  and control interface units  80  into a graphic representing the floor plan of the location where the units are installed for easy reference using the specially designed interactive configuration software running on a smart phone or preferably a tablet or computer system. In case of a large office located in a building, a graphic representation of the façade can also be created. A special illumination plan can then be created using the interactive light units  20  located at the immediate vicinity of windows or purposely installed on the façade to produce patterns that can be seen from the street. These patterns may be animated and produce a Christmas tree, blinking stars, snow or rain drops falling, logos or any other suitable design. Text and moving messages may also be displayed depending on each particular case. 
     The interactive units can be configured to respond to group commands by issuing a series of configuration commands that do not need to be immediately relayed to all units. After any configuration change the controller  10  will begin to send the necessary commands to all affected units until the update is complete. In case of a large number of interactive units in the system  60  or many control interface units  80  of different types requiring additional information, a short delay may occur in performing this communication but because in basic operation this is a relatively rare event that runs in the background and does not need to be completed in real time a short system delay may be acceptable to provide time for the operation to be completed. 
     During normal operation, the configuration of group commands and the presence of an adequate number of actuators  50  may result in satisfactory performance levels. In that way a single controller  10  may be able to control a large number of interactive units. However practical limitations may cause the time needed to manage a high number of devices to increase rapidly especially if communicating over a low bandwidth medium such as the AC mains  35  and/or a large volume of configuration or operational data must be exchanged. If wireless communication is used the range may not be sufficient to reach all interactive units in a big building. To circumvent that, slave controllers  12  can be used, dividing the AC mains  35  power infrastructure into two or more areas by means of installing dynamically configurable filters and bridges in circuit breaker boxes so that each controller  10  and  12  is given its own area of actuation with an adequate number of control units within the limits imposed by the desired performance. Different wireless channels can be programmed to achieve a similar effect when using wireless communication. 
     The master and slave controllers  10  and  12  can then be set to communicate over a high bandwidth channel allowing the master  10  access to all interactive units within the system  60 . All relevant information for the system configuration and areas selected for each control unit  10  is mirrored on all control units  10  so that any slave controllers  12  can assume the master role in response to a user command or following a priority list in case of failure of the current master  10  ensuring high reliability and flexibility of operation. In the event of failure of a slave control unit  12 , the system  60  can automatically detect the problem and send a command to reconfigure the bridges and filters on the affected circuit boxes so that the orphan units can be momentarily overtaken by another slave controller  12  located in the vicinity according to a contingency plan allowing for continuous access to all interactive units in the system  60  despite some performance degradation that may be inevitable. A replacement control unit  10  need only to be installed at the proper location and once powered up the new control unit  12  will automatically identify the master controller  10 , download the configuration maps and upon verification of the individual addresses of the orphaned interactive units within its controlling range, automatically identify its role and assume the functions of the previous slave control unit  12  that was replaced.
