       FIELD OF INVENTION 
       [0004]    The present invention relates to the field of portable lighting systems and devices. More specifically, the invention is directed to the field of portable lighting systems and devices utilizing multiple sources of power. 
       BACKGROUND OF THE INVENTION 
       [0005]    A solar power system uses one or more solar panels to convert sunlight into electricity. Solar power systems consist of multiple components, including the photovoltaic modules, mechanical and electrical connections and mountings and means of regulating or modifying the electrical output. A wind power system uses one or more wind turbines to convert wind into electricity. Solar power and wind power devices have been supplying power to many fixed structures such as homes, buildings and other structures. The solar panels and wind turbines can be placed on the roofs of these structures or at areas of land adjacent to the structures. This configuration works well with fixed buildings because the panels or turbines can be mounted and left indefinitely. However, in some applications, temporary or emergency electrical power may be needed. 
         [0006]    Stand alone portable power systems are generally manufactured by mounting various components to a trailer or frame. Stand alone portable solar power systems have many uses. For example, road construction or maintenance is preferably done at night when traffic is low, and the effect on drivers and traffic is minimized. Other construction is performed during the night as well when deadlines or weather patterns dictate. Additionally, sporting and entertainment events can benefit from portable lighting systems when the venues are not equipped with their own lighting systems. 
         [0007]    Generally, at night construction sites, large lights are used to illuminate the work area so that the workers are able to see. Generally, these large lights are high wattage lights which run using a diesel powered generator. With the volatility of oil prices, diesel is, at times, very expensive, causing the cost of using the lights to increase substantially. Tower lights are generally diesel powered, producing unwanted noise and pollution. Solar powered tower lights tend to be unwieldy in terms of size and shape. Light components are generally supported by masts which are folded horizontally flat on the structure component, a configuration which tends to damage the solar panels. 
         [0008]    What is needed is economical mobile renewable energy light tower which is small and lightweight, easily transported on conventional trucks or towed with a standard trailer hitch, which can provide reliable emergency light. 
       SUMMARY OF THE INVENTION 
       [0009]    In accordance with the present invention, there is provided an mobile apparatus that enables light to be provided to locations not connected to the energy grid. The present invention discloses a mobile renewable energy light tower (“MRE Light Tower”). 
         [0010]    In one embodiment of the present invention, a MRE Light Tower is comprised of a trailer frame component, a mast component connected at its base to the trailer frame component, a utility bar component connected at the top of the mast component, some lights attached to the utility bar, a battery system mounted on the trailer frame component, a power management component mounted on the trailer frame component and electrically connected to the battery system, a renewable energy component, and a backup energy component. In an embodiment, the MRE Light Tower has a fuel component comprising the backup energy component. 
         [0011]    The trailer frame component provides the framework to secure and transport the other components comprising the MRE Light Tower, including the mast component, the utility bar component, the power management component, the battery system, along with other components such as a solar component, a fuel component, a wind component, an outlet component, a plug-in component, a network component, and a surveillance component. 
         [0012]    The trailer frame component can comprise a trailer which can include a frame, an axle coupled to the frame, wheels coupled to the axle, a hitch coupled to a front end of the frame, and a stand for supporting the trailer frame when the MRE Light Tower is not being towed. The front end of the frame can comprise a flat surface upon which to mount a mast component; the remainder of the trailer frame can comprise a bed comprised of steel in a rectangular configuration with perimeter walls protruding upwards, constituting a secondary double wall containment system for all other components. As other components may contain effluents, the double wall containment system thereby contains any effluents that may leak out from any of the other components, thereby protecting the environment from potential contamination. In one embodiment, the double wall containment system is DOT approved. In one embodiment of the present invention, the frame component has forklift receptacles on each side, enabling the unit to be easily loaded and unloaded from the side of a flatbed truck. In an embodiment, the axle can be configured to fit about a 5.2 foot trailer width. In an embodiment, the hitch is a standard pintle hitch for ease of towing. 
         [0013]    In an embodiment, the power management component and battery system can be mounted on an interior component mount, allowing the entire electrical system installation to be completed away from the trailer frame component, and providing additional safety and stability for the MRE Light Tower. The interior component mount comprises a metal frame upon which the battery system and power management components are mounted. In one embodiment, a backup energy component comprising a fuel tank and generator is mounted on one side of the trailer frame component and the battery system and power management component are mounted on the interior component mount, which can then be lowered down and mounted onto the centerline of trailer frame component for final installation, wherein the battery system is thereby positioned on the other side from the backup energy component. As the battery system is primarily comprised of batteries and which comprise a substantial portion of the weight of the device, and the backup energy component can comprise a fuel tank and generator also comprising a substantial portion of the weight of the MRE Light Tower, mounting the battery system on the opposite side from the backup energy component provides increased stability. 
         [0014]    In an embodiment, the MRE Light Tower can also include a cover coupled to the top of the frame comprising the bed to protect a power management component and battery system. In an embodiment, the cover can also protect a backup energy component. In an embodiment, a backup energy component comprising a generator and fuel tank can be mounted and supported a safe distance from the battery system mounted on the other side of bed. In an embodiment, brackets can be attached to the top of the cover to support a solar component. In an embodiment, the cover is provided with ventilation for the enclosed power management component. In an embodiment, the cover is provided with ventilation for an enclosed backup energy component. 
         [0015]    In an embodiment, the MRE Light Tower should be easily towed on public roads and the MRE Light Tower should fit within standard traffic lanes when in transport mode. The width may be about 5 feet to 8.5 feet, which is the maximum legal width for most U.S. highways. In an embodiment, the width is 5.2 feet, which allows maximum efficiency in transporting the MRE Light Towers on trucks. The length of the MRE Light Tower can be about 10 to 20 feet in length. In an embodiment, the length of the MRE Light Tower is 10.5 feet, which allows maximum efficiency in transporting the MRE Light Towers on trucks. The frame component can be made of steel tubing which can have circular, square or rectangular cross sections. For example, the frame may be made of 2″×3″ or 3″×3″ steel tube. 
         [0016]    In an embodiment, the trailer frame component can support an interior component mount with a power management component and battery system mounted thereon, a mast component on the front end, a backup energy component on brackets above the bed, and a solar component on the cover. 
         [0017]    The mast component is used to raise the utility bar component comprising a light component to the appropriate level for optimum lighting. The bottom of the mast component can be attached to the front end of the front end of the trailer frame component. The top of the mast component can be coupled to the utility bar component. In an embodiment, the top of the mast component can also be coupled to a wind component. 
         [0018]    In an embodiment, the mast component comprises a base support, a mast, a conduit, and a winch. A base support can comprise a stanchion, a plurality of flanges, a mast ring, and a base plate. A mast can comprise a base section, a ring interface, and a plurality of telescoping sections. 
         [0019]    In an embodiment, the stanchion is a piece of vertically oriented steel square tube with flanges welded on each side of the lower end of the steel tube. In an embodiment, the base support is integrated with the structure component. The bottom of the steel tube and four flanges are welded to the front end of the frame of the structure component. On the front face of the lower end of the steel tube, a base plate is fixedly attached. The base plate has a hole capable of receiving a bolt, and is mounted high enough such that a nut may be affixed to the received bolt without impinging on the front end of the frame of the structure component. On the front face of the upper end of the steel tube, a ring is attached. On the back face of the steel tube, a conduit is fixedly attached. 
         [0020]    The light component can be coupled directly to the top of the mast component, or to a utility bar component coupled to the top of the mast component, such that the light component can be raised to the optimum height for providing illumination. In an embodiment, the light component can comprise a light bar, light bar extensions, a plurality of brackets, and a plurality of lights. The light bar can be steel tubing configured in a t-junction such that the stem can be coupled to the topmost section of the mast, and both sides of the cross-member are configured to receive light bar extensions. The light bar extension can also be steel tubing of a smaller diameter than the cross-member of the light bar, such that the light bar extensions can rotate axially when coupled with the cross-member. Brackets can be fixedly attached to the light bar extensions. Lights can be fixedly attached to the brackets. Consequently, when the MRE Light Tower is deployed, the lights can be adjusted by swiveling the light bar extensions around a horizontal axis, and by swiveling the base section of the mast component around a vertical axis. 
         [0021]    A variety of materials may be used in the lights. Preferably, the lights provide adequate lighting for a desired task, durability, relatively low power requirements, and a relatively long-life cycle operation. In specific embodiments, the lights may be selected from the group consisting of light emitting diodes, electrodeless induction floodlights, gas discharge lamps, and combinations thereof. 
         [0022]    In an embodiment, the lights are 100 w LEDs. In an embodiment, four lights are mounted two each on the light bar extensions and one light mounted on the cross-member above the stem mounted to the upper portion of the mast. In an embodiment, the lights are controlled by a digital programmable timer. In an embodiment, the lights provide illumination coverage for an area of between four and six acres. In an embodiment, the lights are capable of providing 45,000 lumens of light. 
         [0023]    The battery system is used to store energy coming in from the solar component, wind component, or backup energy component, and usually comprises a plurality of batteries. The power management component interfaces between the battery system and the energy generation components and energy utilization components, and can comprise a charge controller, an AC/DC power center, and an inverter. In an embodiment, the power management component can also include a transformer. In an embodiment, the batteries can be lead acid batteries. In another embodiment, the batteries are lithium-ion batteries. In an embodiment with lithium-ion batteries, the MRE Light Tower will weigh much less, enabling the frame component to utilize a smaller axle. The weight savings also enable the MRE Light Tower to be towed by a smaller vehicle, and to utilize more robust components elsewhere. In one embodiment of the present invention, a MRE Light Tower utilizing lithium-ion batteries weighs less than 1900 pounds. However, in other embodiments, any other type of rechargeable battery can be used. A charge controller may be incorporated in the power management component between the solar component and the battery system. The charge controller can be used to prevent battery damage from excessive charging or discharging. The voltage output from the solar component can be proportional to the amount of sunlight that is collected by the solar panels. However, excessive voltage can damage the batteries. Thus, the charge controller is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar component rises, the charge controller regulates the charge to the batteries to prevent any over charging. 
         [0024]    The charge controller can have a three stage charge cycle which includes bulk, absorption and float stages. During the bulk stage of the charge cycle, the charge controller can let the charge voltage to the battery gradually rise to the bulk level. In an embodiment, the batteries can be configured in series so that cumulative voltage is 48 volts. The bulk level can be between about 57.6 and 58.4 volts while the batteries draw maximum current. When the bulk level voltage is reached by the batteries, the absorption stage begins. During the absorption stage, the battery voltage can be maintained at bulk voltage level for a specified time while the current gradually tapers off as the batteries charge up. 
         [0025]    After the absorption time passes, the battery voltage can be lowered to float level which can be between about 53.6 to 54.4 volts and the batteries can draw a small maintenance current until the next cycle. 
         [0026]    The charge controller can use Pulse Width Modulation (PWM) or Maximum Power Point Tracking (MPPT). If the charge controller includes MPPT, the charge controller can match the output of the solar panels to the battery voltage to insure maximum charge (amps). A MPPT type charge controller can compensate for a low battery voltage by delivering increased current if the battery voltage is below the optimum level. This adjustment allows the MPPT charge controller to always output the optimum charging power to the battery. In a preferred embodiment, the battery is fully charged prior to delivering the MRE Light Tower to the application site. 
         [0027]    An AC/DC power center can be coupled between the charge controller and the battery. The DC portion of the AC/DC power center can include various breakers and bypass switches. For example, the AC/DC power center may include a first DC breaker which prevents excessive current from being transmitted from the solar component to the batteries and a second DC breaker which prevents excessive power from being drawn from the system. In an embodiment, the first and second DC breakers may each be set for 250 A. The 20 AC/DC power center can also include an AC section which can include a switch which can break the AC power from the inverter to the light component. In an embodiment, the AC/DC power center can be a Magnum MMP 250-60S. 
         [0028]    Power from the battery and solar arrays can be transmitted through the AC/DC power center to an inverter to convert the direct current (DC) electrical energy into alternating current (AC). For example, in an embodiment, the solar panel arrays may each product 48 volts DC and the batteries may be configured to store electrical power with a 48 volt DC output. The inverter may convert the DC voltage from the solar component and the batteries into an AC output. For example, the inverter can convert 48 volt DC into 120 volt AC with a cycle frequency of 60 Hz. In other embodiments the voltage output can be any other suitable level. In an embodiment, the inverter can be a Sunny Island 4548-US or 6048-US. 
         [0029]    In an embodiment, the plurality of batteries is comprised of 48 Volt Deep Cycle Industrial batteries providing 510 AMP hours @ 48V Nominal. 
         [0030]    The backup energy component, which can comprise a generator and a fuel tank, provides additional energy on demand to the power management component when insufficient energy is provided by other components, such as a solar component or a wind component. In an embodiment, the device uses less than one gallon of fuel for every one night of usage, providing as much as 75% savings in diesel usage and cost. In an embodiment, the generator can be a Cummins Onan Diesel, 120 Volt 50 AMP System. 
         [0031]    In one embodiment of the present invention, the solar component can comprise one or more solar arrays which convert sunlight into electricity. The solar arrays are electrically coupled to the power management component, which in turn is connected to the battery system and the power generated by the solar arrays is stored and buffered within the batteries of the battery system. The solar component is coupled to the power management component by a power cable which is routed through the conduit of the mast component. 
         [0032]    The wind component can be comprised of a turbine that generates electricity from the kinetic energy of wind. In an embodiment, a charge controller is integrated into the wind component to convert AC to DC for transmission to the power management component. In an embodiment, the turbine is configured to generate DC, obviating the need for an integrated charge controller. The wind component is electrically connected to the power management component. 
         [0033]    In an embodiment, a plug-in component is incorporated into the device so that the battery system can be charged from a traditional electrical outlet if one happens to be available. 
         [0034]    In an embodiment, an outlet component is incorporated into the device. An outlet component can comprise a 120V 20 Amp receptacle. 
         [0035]    In an embodiment, a WiFi component is incorporated into the device. In an embodiment, the WiFi component can be communicatively coupled with other components, such as the power management component, wherein data about power usages can be transmitted, and control functions and commands can be received over the WiFi connection. 
         [0036]    In an embodiment, a surveillance component can be mounted on the top of the mast component. The surveillance component can be comprised of a video camera, means for mounting the video camera on the mast component, and means for storing video data. In another embodiment, the surveillance component is communicatively coupled with a WiFi component, allowing video data to be accessed or streamed over a WiFi connection. In another embodiment, the surveillance component is communicatively connected to a cellular component, allowing video data to be accessed or streamed over a cellular connection.
