     FIELD OF THE INVENTION 
     The present invention relates to systems and methods of powering lights of passenger vehicles, especially all-day lights on, hybrid and electrical vehicles, trucks, motorcycles, trains, ships, even boats, all of which are simply called vehicles and more particularly to systems and methods that employ a thermal and light energy dispersed by a vehicle regular illuminating light bulb and solar energy to power the emergency and parking lights of the vehicle that further in the text are called safety lights when the electrical system of the vehicle is turned off and the vehicle regular electrical sources are not available. 
     BACKGROUND OF THE INVENTION 
     There are different kinds of vehicle illuminating and safety lights. A vehicle headlight assembly, for example, may be equipped with a light source, at least one reflecting surface, a projection lens, and a shutter located in the vicinity of a focus of the projection lens. Light rays reflected by the reflecting surface and directly coming from the light source provide a focused image of light. The projection lens projects the focused image of light into a forward direction and illuminates a predetermined area on a road. The shutter cuts off an unnecessary portion of light for the formation of light distribution pattern of the vehicle light. The unnecessary portion of light is typically a portion which generally illuminates in the direction of the vehicle, which can be a glare light to a driver of a car driving in an on-coming lane. 
     The light source of the vehicle headlight and all other vehicle warning, illuminating, safety, tail, brake, stop, etc. lights may consist of an incandescent bulb, a halogen source, a light emitting diode (LED) based source, etc. All these types of light sources are powered by the vehicle electrical system. The lights are typically dark when an engine is shut down. From a safety point of view, it is important to keep the vehicle light turned on as an emergency or safety light when a vehicle is parked, especially during the dark part of day. But the operator of a vehicle can&#39;t leave them turned on for a long period of time when the engine is shut down because a battery will become discharged. 
     There is a need for a method and system to collect and save multi-energy to power the emergency and parking lights when the regular vehicle electrical sources are not available. 
     SUMMARY OF THE INVENTION 
     A system and method to collect and store thermal (infrared) and light (visible) energy dispersed by a vehicle regular illuminating light and, together with also collected and stored solar energy, to employ this combined stored multi-energy to power the safety lights of this vehicle and to use the rest of this stored multi-energy to power an electrical system of the vehicle or any its units are presented. 
     The present invention provides a method and system to collect and store thermal and light energy dispersed by a regular vehicle light source and use this stored multi-energy to power the safety lights when the electrical system of said vehicle is turned off and its regular electrical sources are not available.

       The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which: 
         FIG. 1  is a schematic diagram of the Multi-Energy vehicle Light system;

     DETAILED DESCRIPTION 
     In accordance with an exemplary embodiment of the present invention a method and system are provided that collect and employ the two different types of energy (Multi-Energy)—infrared and visible light energy—to keep a vehicle safety lights turned on when the vehicle is parked, especially in darkness, and the electrical system of the vehicle is turned off, powered by energy that was collected and saved by a multi-energy source (MES) module, and the method comprises Multi-Energy Illuminating Technology (MUEL-T). As used herein and in one non-limiting exemplary embodiment Multi-Energy Illuminating Technology is the combination of a multi-energy source module having at least one photovoltaic device configured to collect infrared energy from the vehicle headlamp bulb or other vehicle surface and at least one photovoltaic device configured to collect visible light energy from the vehicle headlamp bulb or other vehicle surface and at least one solar energy source module. 
     Another exemplary embodiment of the present invention allows a method to improve safety of any vehicle by powering its safety lights at night or in darkness independent of weather conditions when the vehicle is in an emergency situation or parked, and an electrical system of the vehicle is not available at that time. 
     Another exemplary embodiment allows a system for powering vehicle&#39;s safety lights at night or in darkness independent of weather conditions when the vehicle is in an emergency situation or parked, and an electrical system of the vehicle is not then available. 
     Yet another exemplary embodiment of the present invention is that a safety light of a Multi-Energy vehicle Light (MUEL) system is powered by the two types of energy to keep the vehicle safety lights turned on at the discretion of an operator when the vehicle is parked and an electrical system of the vehicle is not available. 
     In addition, and as yet another exemplary embodiment of the present invention, the multi-energy MUEL system accomplished by the MUEL-T technology includes the two energy sources. The first energy source of the MUEL system and method is the multi-energy source MES module that collects and transforms to electricity by photovoltaic devices and stores by rechargeable battery a thermal and light energy dispersed by a vehicle regular illuminating light bulb such as a headlight when the light is turned on. 
     The MES module collects the waste light and infrared energy of a vehicle regular illuminating light bulb at any time when the MUEL light bulb, which is next to the MES module, is turned on at the discretion of the operator of the vehicle. In exemplary embodiment, one set of the photovoltaic devices of the MES module accomplished by the MUEL-T technology is designated to convert waste light energy of a vehicle regular illuminating light bulb to electrical energy and has light wavelength. This set of the photovoltaic devices may be fixed on the side of the MES module that is closer to the MUEL light bulb. 
     The second set of the photovoltaic devices of the MES module accomplished by the MUEL-T technology is designated to convert waste infrared energy of a vehicle regular illuminating light bulb to electrical energy and has an infrared wavelength. This set of the photovoltaic devices may be fixed on the other side of the MES module. 
     As an alternative embodiment another than photovoltaic suitable type of energy converters may be employed to transform to electricity the waste heating energy dispersed by the MUEL light bulb. For example, flat nanoantenna (nantenna) electromagnetic collectors (NECs) may be used for producing electricity from thermal energy. NEC devices target midinfrared wavelengths where conventional photovoltaic solar cells are inefficient. Nantennas with embedded rectifiers into the antenna structures can collect as well as convert into electricity waste heating energy dispersed by the MUEL vehicle regular illuminating light bulb. 
     Additionally, the internal lateral surfaces and bottom surface of a MUEL light assembly around the bulb may be covered by the flat nanoantenna (nantenna) electromagnetic collectors with embedded rectifiers, which in this case will work as collectors of thermal energy, coolers of inside temperature, and reflectors of the bulb of the MUEL light assembly. 
     The second energy source of the MUEL system and method is a Solar Energy Source (SES) module that consists of photovoltaic devices that have light wavelength. The goal of the SES module is to provide MUEL system with solar energy, and it may be located at any appropriate part of the MUEL system that provides access to solar energy. 
     Another exemplary embodiment of the present invention is that a SES module and a MES module accomplished by the MUEL-T technology may be manufactured as a combined “sandwich” (MESES) module, in which the MES module is located next to a MUEL light bulb, and the SES module on another side of the MESES module has access to the sunlight. 
     Exemplary embodiments of the present invention allow a MUEL light accomplished by the MUEL-T technology to consist at least one MES module or at least one MES module and at least one SES module or at least one MESES module or at least one MESES module and at least one SES module. 
     A schematic diagram of the preferred embodiment of the MUEL system  10  accomplished by the MUEL-T technology is shown in  FIG. 1 . A vehicle multi-energy MUEL system  10  consists of the MES module  30  that is a part of the MESES “sandwich” energy collector  11 , which collects both solar energy and waste visible (light) and heating (infrared) energy of the light bulb  13 , the SES modules  31   a ,  31   b ,  31   c , where the first of which is a part of the MESES “sandwich”  11 , and all of these SES modules collect solar energy and are connected to the rechargeable battery  33  through the diodes  37 , which prevent the battery&#39;s current from flowing back through the photovoltaic module, the vehicle safety light  32  that may be a light emitting diode (LED) based or other lighting source, the light sensors  34 ,  34   b ,  34   c , the microcontroller unit  35 , the charger  36 , the switches  38 ,  39 ,  44 ,  49 , the measurement resistors  40 ,  42 , and operational amplifiers  41 ,  43 . At night the photovoltaic modules  31   a ,  31   b , and  31   c  stop to produce energy from solar light. The light sensor  34   b  turns on vehicle safety light  32  through switch  38  in darkness if vehicle headlight bulb  13  of the light  12  is not turned on and switch  39 , controlled by the light sensor  34  is not turned off. When the rechargeable battery  33  is charged, vehicle safety light  32  will shine at night or in darkness and will provide safe parking of a vehicle or safe location of the vehicle on a road in case of an emergency stop. 
     In addition, and as yet another exemplary embodiment of the present invention, the MUEL system accomplished by the MUEL-T technology is configured with a microcontroller unit (MCU)  35  that monitors energy collected by MES  30  and SES  31  modules by use of a voltage drop across resistor  40 . This voltage is amplified by an operational amplifier  41  and is processed by the MCU  35  on its ADC1 (Analog-to-Digital Converter) terminal. The amount of energy delivered to the rechargeable battery  33  is memorized by MCU  35 . The MCU  35  monitors the energy lost by a rechargeable battery  33  while serving the safety light by analyzing a voltage drop across resistor  42 . This voltage is amplified by operational amplifier  43  and is processed by the MCU  35  on its ADC2 terminal. When light sensor  34   b  of the SES module turns off the safety light in a sunny morning, the MCU calculates the residual of the collected energy by the MUEL. If enough energy is left, MCU through its terminal I/O 1  switches the output terminal of the rechargeable battery through switch  44  from the position of providing service to the safety light  32  line to the position of powering any electrical energy consumer line of the vehicle electrical system. 
     Yet another exemplary embodiment of the present invention is that the multi-energy MES module  30  of the MUEL system accomplished by the MUEL-T technology is fixed next to the MUEL light bulb  13 . 
     Another exemplary embodiment of the present invention is that the rechargeable battery may be fixed at the light assembly accomplished by the MUEL-T technology in the same way as a light bulb. If more than one rechargeable battery is used, they may be arranged in a parallel or a series combination. 
     Another exemplary embodiment of the present invention is that the rechargeable battery may be located in a special compartment in the hood of a vehicle and connected to the MUEL by the same connector to which a bulb is connected. Part of the schematic may be located in the same compartment as the rechargeable battery. 
     Another exemplary embodiment of the present invention is that there are openings in the MUEL assembly accomplished by the MUEL-T technology above the SES modules to get sunlight by the photovoltaic devices  31   a ,  31   b , and  31   c . The openings are closed by glass or other material that protects solar modules from mechanical damage and are transparent to solar energy. 
     Another exemplary embodiment of the present invention allows a retractable cover above the SES module of the MUEL. 
     Another exemplary embodiment of the present invention is that the vehicle MUEL system accomplished by the MUEL-T technology may store energy that it collects through MES module both light and infrared energy at any time when the light bulb of the MUEL is turned on and solar energy through SES modules on sunny days. MUEL system may store energy that it collects through both MES and SES solar energy on sunny days when the light bulb of the MUEL is turned off. 
     Another exemplary embodiment of the present invention is that location of the SES module may be anywhere in the MUEL system. If the size of the vehicle light assembly allows, there may be more than one SES module in the MUEL light accomplished by the MUEL-T technology. 
       FIG. 2  shows a simplified MUEL system  10  headlight assembly accomplished by the MUEL-T technology. A MUEL assembly consists of a headlight bulb  13 , a sandwich MESES  49 , and safety light  32 . The sandwich MESES  49  in turn consists of a MES module  30  and SES module  31   a . The MES module  30  located next to the light bulb  13  and includes a light sensor  34 . The SES module  31   a  located above the MES module  30  and includes a light sensor  34   a . The MUEL assembly also consists of another SES module  31   b , which includes a light sensor  34   b .  FIG. 2  also shows a direction of a headlight beam  47 . The two internal lateral surfaces and bottom surface  48  of the MUEL assembly are employed as reflectors. The MES module  30  collects both waste light and waste infrared energy dispersed by the light bulb  13  of the MUEL system at any time when it is turned on. The SES module  31   a  and SES module  31   b  both collect solar energy on sunny days. 
     Another exemplary embodiment of the present invention is that depending on an internal structure of the MUEL light assembly the location of modules accomplished by the MUEL-T technology is chosen in a way when they collect the most of infrared and visible energy. Each employed MES and SES module may contain at least one light sensor. 
     Yet another exemplary embodiment of the present invention is that each MES module light of the MUEL system accomplished by the MUEL-T technology is located in the area of the vehicle illuminating light bulb in which it consumes most of the waste by the bulb thermal and light energy and does not disturb the characteristics of the light, and the ambient temperature of the MES is in the allowed range. 
     In addition, and as yet another exemplary embodiment of the present invention, the two or more regular vehicle lights (for example, headlights, parking lights, side-marker lights, etc.) may be combined in one assembly to create a Combined MUEL (COMUEL) light system accomplished by the MUEL-T technology. 
     Yet another exemplary embodiment of the present invention is that each SES module of the MUEL system accomplished by the MUEL-T technology is located in the area of the light assembly where it consumes most of the solar energy and does not disturb the characteristics of the light, and the ambient temperature of the SES is in the allowed range. 
     Table 1 shows the conditions of the rechargeable battery and safety light of a MUEL system accomplished by the MUEL-T technology depending on weather and time of day. 
     Another exemplary embodiment of the present invention is that the charger  36  is used to prevent the rechargeable battery from overcharging by employing the signal I/O 3  of the MCU  35 . The charger  36  may also be employed when there is more than one SES module. The charger and rechargeable battery may be fixed in the MUEL assembly or outside of it.
