Description

BACKGROUND OF THE INVENTION

The invention is a lighting system and method (collectively the “system”). The system uses modular components that enable users to implement effective and robust lighting configurations designed to address the lighting requirements of the particular users and operating environments of the system. The system was originally conceptualized for use in the interior of a truck trailer, but the system can be implemented in other environments.

The trucking industry is critical to the economy of the United States. According to the markets.businessinser.com website, the domestic trucking industry in the U.S. generated just over $700 billion dollars in 2017. This is larger than the GDP of all but 32 countries in the world. According to the Bureau of Labor Statistics in 2018, 5.8% of all full-time workers in the US have jobs in the trucking industry. 10.8 billion tons of freight were moved via truck in 2017 according the American Trucking Associations. Trucks are reported to move 70% of all goods transported in the US. Some experts have predicted that most grocery stores would start running out of food within just 3 days after long-haul truckers stopped working. The average professional long-haul trucker logs more than 100,000 miles per year. Throughout the 2020 COVID-19 pandemic, truck drivers have been classified as essential personnel. Truck freight is expected to grow by 6% in 2021.

Given the importance of truck freight to the economy, the trailer of a truck is precious and yet non-optimized real estate. The interior of the trailer is repeatedly loaded and unloaded. The loading and unloading of a trailer interior often occur at nighttime or in otherwise inadequate light from dark conditions resulting from poor lighting with the trailer itself. Despite the importance of trucking and the need for a well-lit interior space during the loading and unloading of the interior of the trailer, prior art lighting technologies are inadequate and lacking in many important ways. Insufficient lighting can often lead to personal injuries, damage to cargo, delays in the unloading and loading of the trailer, and the otherwise needlessly non-optimal loading and unloading of the trailer,

Prior art solutions to the problem of trailer lighting inevitably suffer from a lack of durability, a lack of configurability, and the constraints of being tethered. Many trailer lighting systems involve extrusions that are subject to being hit by forklifts during the loading or unloading of the trailer, resulting in such lights being damaged and/or dislodged.

Prior art lighting systems utilized within the interiors of trailers typically use flat structures, which result in non-dimensional LED emission. This creates a work environment that is literally uncomfortable for human beings. Conventional power control boards often have problems caused by high temperatures and the absence of a heat sink and are prone to electrical shorts caused by condensation, which can be a common occurrence resulting from different temperatures within the interior and exterior of the trailer. Such systems utilize fragile two-connectors without universal port connections. Soldering, scotch lock failures, difficult component replacements, and other undesirable attributes plague such prior art approaches.

It would be desirable for a more resilient, efficient, modular, customizable, and easy to install lighting system to be incorporated into the trailer interiors used in the trucking industry today.

The system is described in greater detail below in the Summary of the Invention section.

SUMMARY OF THE INVENTION

The invention is a lighting system and method (collectively the “system”). The system uses modular components that enable users to implement effective, robust, and highly configurable lighting configurations that address the lighting requirements of the particular users and operating environments of the system. The system was originally conceptualized for use in the interior of a truck trailer, but the system can be implemented in other environments.

The system can use a power box to power multiple LED assemblies used to generate light. The system can be implemented as recess lights in between the ribs near the ceiling in the interior area.

The system can be manufactured and sold as a “kit” that mechanics, technicians, truck drivers themselves, or other personnel can install within the interior of the trailer. The system can be utilized to light the interior of the trailer whether or not the trailer is attached to the tractor at that time. The untethered trailer can draw power from a batter within the power box to provide the desired lighting. The luminosity of the system can be implemented in a substantially modular manner, with lighting components and/or batteries being added or subtracted. In many embodiments, it may be optimal to use 8 lights to best luminate the interior of a semi-trailer, with the expectation of generating 5 hours of continuous light before the recharging of the battery is required. The battery can be recharged through the use of solar panels, the power system of the trailer, or an external power source.

The system can be better understood by referencing the drawings discussed below.

DETAILED DESCRIPTION

The invention relates generally to the systems and methods for illuminating a space. More specifically, the invention is system and method for lighting the interior of a trailer (collectively the “system”). All element names and element numbers are listed and defined in Table 1 below.

I. ALTERNATIVE EMBODIMENTS

Different examples of various attributes, components, and configurations that can be incorporated into system 100 are illustrated in the drawings and described in Table 1. However, no patent application can expressly disclose in words or in drawings, all of the potential embodiments of an invention in a comprehensive manner. In accordance with the provisions of the patent statutes, the principles, functions, and modes of operation of the system 100 are illustrated in certain preferred embodiments. However, it must be understood that the system 100 may be practiced otherwise than is specifically illustrated without departing from its spirit or scope. Alternative embodiments of the system 100 can be described and categorized on the basis of a variety of variables, such as number of LED assemblies, different types of ways to recharge the battery 210, different positional and geometry configurations within the interior space 90, etc.

II. ADVANTAGES TO USERS

The system can be implemented in such a manner as to vastly improve the safety and productivity of loading and unloading trucks.

The battery in the power box allows the system to illuminate the interior of a truck even when the trailer is not tethered to the tractor and its power source.

The system is highly configurable, so the different numbers of light assemblies can be installed in different configurations to meet the needs of the particular operating environment as well as the operators of the truck.

The components of the system are easy to install. When coupled with the highly modular nature of the components, it would be easy to sell the system as “kits”!

Current lighting solutions are difficult to fasten to specific locations, and they are easily damaged by high temperatures, the impact of condensation on electronic components, and the physical impact of loading and unloading cargo from the cargo area. The system can be implemented almost exclusively in the unused or at least underused overhead space above the ribs and above the cargo space of the interior. Only the very thin light assemblies take up any cargo space, and as recess lights, they take only a sliver.

The power box which in a preferred embodiment is affixed to a surface in the overhead space provides an electrical infrastructure that is useful for lighting, is capable of being charged through variety of different means, including the battery in the tractor, a connected solar power assembly, or even by plugging in to a conventional power outlet. That electrical infrastructure can find additional uses in the future that have little to do with lighting.

By using “smart” processors, energy consumption can be minimized, risk to equipment avoided, and the storing of electricity for a later time can be maximized. The system can deliver 5-8 hours of lighting between charges, which is more than enough for a typical loading and unloading of the cargo area.

By including a motion detector in each lighting assembly, illumination is provided as needed. There is no reason to light up an entire 53-foot-long trailer if only a small portion is being used. Each lighting assembly is “smart” with its own infrared sensor, LED lights, and motion detector.

IV. OVERVIEW

The system 100 is a more resilient, modular, and efficient way to light the interior space of a trailer. It can function when the trailer is standing alone, separate, detached, and untethered from the tractor. However, while the trailer is attached to the trailer, the battery used to power to lights of the system can draw power from the tractor. The system uses sensors to only activate lights that are in areas where they are needed. The system can be sold as a kit that is implemented into existing trailers, and it is easy to configure and install. Luminosity can be customized by adding or subtracting lights, as the system can be extremely modular in its design and capabilities. The battery can be recharged through the use of solar panels, the tractor battery, or an external AC outlet.

The cone-shaped geometry of the light guide in the LED assembly makes the LED emission highly directional. This is something that is applicable for Semi trailer use from the height it is located, the brightness being omitted, and the number of lights being mounted to cover a 53-foot-long interior with overlapping lamps.

The circuit board in the light assembly can be laid out for maximum efficiency for heat, and allows prewiring, and motion sensing, and voltage regulation. There is a heat sink to hold the circuit board away from the ceiling. The size of the lamp itself to hide under a ceiling strut. It is also made of durable and light way materials to withstand the environment of the trailer, include large semi-trailers.

The power box holds the battery and a circuit board that controls the charging and utilization of the batter. The power box cane be mounted using fasteners to a surface in the trailer, preferably surfaces in the overhead space. The circuit board in the power box can recharge itself using connections for solar and reverse polarity protection. The foam mounting on the battery for durability. The power box circuit board is protected and utilizes easy to connect and disconnect cables.

The light assemblies use a highly reliable trunk cable to draw power from the battery box using durable and small connectors that are one way. Any port may work in a “plug and play” fashion. The operator can connect as many or as few as desired. No soldering, no scotch lock failures, and individual LEDs in need of replacing can be easily replaced on an individual basis given the modular design. The lights are placed in between the ribs, recessed, that is why they can only be so deep in their assembly. They must be below the ribs. During installation it would be wise to set them close to the rib for further protection.

The power box houses a battery that can be replaced, if need be, and it houses the circuit board for the controlling of current to lights and redirection of charge to battery for recharging. It also protects from voltage spikes and current reversal.

Because of the battery system the lights can be used for up to 5 hours continuously while the trailer is dropped, and then recharge can happen with three methods.

Each light assembly can have its own motion sensor, its own circuit board, and multiple LED lights. The circuit board can also regulate voltage and wiring that that is a long a 53 trailer present an issue with voltage drop.

The light is thin and has self-sticking adhesive. Each light has its own motion sensor it will save charge/life, and only light in area of continuous work. Each light body is made to lift the circuit board away from the hot trailer roof for longer life of the components. Each light can have a lens that directs the most efficient pattern to the trailer. Each light is pre-wired in advance prior to installation. The truck cable is already bound in loomed. The truck cable has a unique mounting attachment for the lights that can be done quickly without scotch locks or error of wiring, saving significant and avoiding the risk of lights not working. The system is truly an entire integrated system for lighting a trailer while being attached and unattached from the tractor with lights specifically designed for the needs inside of a trailer, along with a thought-out process for installation, and life longevity.

FIG. 1B is a rear-view diagram illustrating an example of a truck 80 that can utilize the system 100.

FIG. 1C is a rear diagram illustrating an example of an interior space 90 in front of the rear doors of the trailer in FIG. 1B.

FIG. 1D is a rear-view diagram of the interior space 90 illustrating an example of ribs 92 dividing the space into cargo space 96 and overhead space 94.

FIG. 1E is a side view diagram illustrating an example of a trailer 84 that can utilize the system 100 that is detached from the tractor 82, an illustration that includes the interior space 90.

FIG. 1F is a side view diagram illustrating an example of the trailer 90, including ribs 92 that mark the border of the cargo space 96 and the overhead space 94.

FIGS. 1G and 1H illustrate the gaps 97 between ribs 92, and that gaps 97 and be filled with panels 98.

Interior lighting within a trailer 84 is made very difficult by a variety of factors. The temperatures can get extremely hot. The purpose of the cargo area 96 is to load, move, and unload cargo. Any lighting configuration implemented in that environment is likely to be damaged by high temperatures and collisions that occur during the loading/unloading process. Furthermore, a trailer 84 has no electrical power when it is not tethered to the tractor 82. The system 100 was conceptualized to address these problems.

VI. SYSTEM AS A WHOLE

To provide better illumination of the trailer 84 during the loading and unloading of the cargo area 96 of the interior 90, the system 100 utilizes the components illustrated in FIG. 2A.

The power box 200 intelligently controls and manages the electrical needs of the system 100. A power box 200 is used to provide electrical power to the system 100 when the trailer 84 is untethered from the tractor 82. A circuit board 221 within the power box 200 can: (1) apply a charge algorithm to manage battery life; (2) involve protection against overcharges; (3) perform cut out function if voltage gets too low; (4) provide reverse battery protection; and (5) vehicle jump start protection.

The light assemblies 300 provide the function of illumination. The light assemblies 300 can use their own circuit board to control the activation of LED lights 310 using a motion sensor 340 sharing the same circuit board. Lights 310 are only used as needed, to minimize the draining of the battery 210 in the power box 200. The light from the LEDs 310 is filtered through a cone-shaped light guide 355 so that the light does not appear overly harsh to human beings.

These two components are electronically linked through a variety of different connectors 400. In a preferred embodiment of the system 100, a trailer harness 410 is used to put the power box 200 in the same circuit as the other components of the system 100. Alternating splitter harnesses 440 and jumper harnesses 470 have error proof mating components to prevent user error and resulting damage to the components of the system 100.

As indicated in FIG. 2B, the system can integrate with other power sources such as a solar power kit 500. Conventional electrical outlets can also be used to charge the battery 210 in the power box 200.

FIG. 2C is a block diagram illustrating an example of the system that includes 1 power box and 8 LED assemblies. This represents a desirable configuration for many semi-trailers 84. FIG. 2C represents a similar configuration, using the preferred connectors of a trailer harness 410, 4 splitter harnesses, and 3 jumper harnesses. The power box 200 and the various connectors 400 can be position in the overhead space 94, where they are unlikely to be damaged in the process of loading and unloading cargo. The only component of the system 100 that must be positioned in the cargo area 96 are the recessed lights of the light assembly 300, which can benefit from being positioned by a rib 92.

FIG. 2E is an example of a view of the ceiling from within the interior space in which the system has been installed.

The system 100 has many advantages. The configuration displayed in FIG. 2C would be the only untethered lighting kit on the market. It can provide 5-8 hours of light between charges. It can be installed easily and is highly configurable. Each light assembly 300 can include its own motion detector 340, so lights are only used as needed—there is no need to light up the entire interior 90 each time. Such as system 100 has components that can are less likely to be damaged, but if they are damaged, they can be easily replaced.

VII. POWER BOX

FIGS. 3A through 3H illustrate different components of the power box 200. In a preferred embodiment, a 12 Vdc AGM batter is used. The power box can perform the functions of an integrated battery manager using the circuit board 320 to implement a various process to prevent overcharging of the battery, damage from low-voltage, reverse battery protection, and provide a basis to jump start the truck 80. The power box 200 can provide a fast on batter connection. The power box 200 can also provide integrated resettable fuse protection.

The processing logic or “brains” of the power box is provided through the charging module 220 and its circuit board 221 which includes a processor.

The 6-way trailer harness 410 and the smart processor on the circuit board 221 of the charging assembly transforms the power box 200 into a manager of the electrical needs of the trailer 84. The trailer harness 410 can access trailer power, ground, inputs for the light assemblies, output for the light assemblies, as well as inputs and outputs for other sources of electricity such as a solar power assembly 500, an exterior electrical outlet, or the battery in the tractor.

The mounting plate 240 of the power box 200 allows the power box 200 to be secured in a variety of desirable and out of the way locations within the interior 80. Impact resistant polycarbonate end caps and anodized aluminum to protect the mounting from moisture and other potential environmental challenges. The batter 210 with in the power box 200 is highly modular and can be replaced without replacing the other components of the power box 200. The charging module 220 is self-contained even within the otherwise contained power box 200. The space for holding the battery 210 provides for error proof battery orientation. Power can ground terminals can be concealed within the battery body to prevent accidental electrical shorts.

The collective impact of a configuration that includes a frame, a foam liner, a self-contained charging module, a top cover and lower cap cover serve to avoid the keep the power box sealed tight from the outside world while also compartmentalizing any interior damage.

VIII. LAMP ASSEMBLY

FIGS. 4A-4J illustrated different components, views, and configurations of the light assemblies 300. The granular functionality of having local processors on the circuit boards 320 with their own lights 310 and their motion detectors 340 to control the lights 310 on that bored. The lens 350 and light guide 355 make the illumination more user friendly. The light guide 355 is cone shaped and made of reflective material in a preferred embodiment of the system 100.

The ability to add, remove, or reposition the lamp assemblies 300 (which can also be referred to as light assemblies 300) provides truck operators which an ongoing and highly flexible illumination infrastructure within the trailers of their trucks.

Each light assembly 300 can include its own circuit board and processor used to monitor, manage, and control a motion sensor and the LED lights affixed to that particular light assembly 300. Thus, the light assemblies 300 function independently of each other even if the electrical power is driven in series through the chain of connectors 400.

The circuit boards 320 and processors of the lamp assemblies 300 can perform onboard voltage compensation to provide uniform light output. The light assemblies 300 can provide “on time”.

In certain contexts, an adhesive may not be the most desirable way to mount the light assemblies 300, in which case cap mounts and fasteners can be used.

VIII. CONNECTORS

FIGS. 5A-5F illustrate different example of connectors 400 and different configurations of connectors 400.

The trailer harness 410 can provide a 6-way connector that integrates the power box into the different components in the trailer 84.

The splitter harness 440 in alternative sequence with the jumper harness 470 provide the ability to add lighting assemblies 300 as desired, or to remove them as desired. FIGS. 5E and 5F illustrated a configuration of connectors 400 that can be used in a preferred embodiment of the system 100.
