[0002] The present disclosure generally relates to mobile rigs equipped with light sources specifically designed for illuminating plants in open fields to control their growth, for example, during nighttime hours.BACKGROUND
[0003] Generally, crops are grown in large fields around the world in a multitude of climates such that they are subject to a multitude of conditions and variables that affect growing performance, crop yield, among other characteristics. Greenhouses are beneficial in that they are able to control growing conditions. Greenhouses, however, are subject to insufficient light, poor ventilation, limited water supply, space constraints, energy costs and so forth. Thus, crop yields for greenhouses are minimal. Light plays a pivotal role in the growth and development of plants. The process of photosynthesis, which is the primary means by which plants produce energy, requires light. In addition to providing energy, light also influences various physiological processes in plants, such as germination, flowering, and fruiting. The duration and intensity of light exposure, as well as the wavelength of the light, can have a profound impact on these processes.

[0034] The present disclosure provides a mobile illumination rig that is configured to traverse a field and provide a uniform source of light to plants planted in the field, as well as apply irrigation in accordance with various embodiments. The mobile illumination rig includes a frame that supports various components. In some implementations, the frame includes a laterally extending member coupled frame ends, where each frame end includes a first vertical member, a second vertical member, and a coupling member that couples the vertical members in an A-frame arrangement. Thus, A-frame ends can be positioned on lateral sides of the mobile illumination rig. A system can include one or more of the mobile illumination rigs, which can be modular and can connect to one another to obtain a larger mobile illumination rig, as can be appreciated.
[0035] The mobile illumination rig includes a plurality of wheels coupled to the frame that facilitate the mobility of the rig across a field, enabling it to navigate across a ground surface of the field. This mobility allows the mobile illumination rig to traverse the field and illuminate the plants planted therein, providing a uniform source of light to the plants as well as irrigating the plants in some embodiments.
[0036] To this end, the mobile illumination rig includes a plurality of light-emitting panels, where, in some implementations, the light-emitting panels are light-emitting diode (LED) light panels or LED strips affixed to a substrate. These light-emitting panels are suspended from the laterally extending member via one or more suspension elements. The suspension elements can include electrical wires, irrigation lines or hoses, stainless steel or other metal cords, chains, and so on, having a fixed or variable length. Electrical wires can electrically couple the light panels to a controller and at least one power source (e.g., battery pack, engine, etc.). This arrangement allows the controller to control the operation of the light panels, including the intensity and wavelength of the light emitted by the light panels.
[0037] In some embodiments, the mobile illumination rig includes a reflective surface positioned above the plurality of light-emitting panels relative to the ground surface. This reflective surface, forming a reflective sheath, can be in a tented arrangement. For instance, two panels can be coupled to one together at an angle to define an apex. The reflective sheath is configured to reflect light emitted by the light panels, thereby enhancing the uniformity of the light distribution across the field. The reflective sheath may be formed of a reflective material, such as polyethylene terephthalate (PET), biaxially-oriented polyethylene terephthalate (BoPET) (e.g., MYLAR®), or like material. In some embodiments, the reflective sheath includes a plurality of reflective sheath edges that extend downward from the sides of the light panels. These reflective sheath edges further enhance the direction and uniformity of light towards the crops planted in the field.
[0038] In various embodiments, the mobile illumination rig can include an irrigation system for irrigating plants. The irrigation system can include one or more sprinklers, hoses, pressure regulators, nozzles, and so forth. In embodiments in which sprinklers are equipped on the rig, the sprinklers can include low energy, precise application sprinklers that deliver water approximately 0.20 m to 0.45 m above the ground to combat wind-drift and prevent evaporation loss. The sprinklers and / or the nozzles thereof can be configured to apply a predetermined water pattern between 0.1 m and 1 m relative to a plant to be irrigated. Insome embodiments, the predetermined water pattern is applied substantially 0.61 m (e.g., ±10% 0.61 m) from the plant.
[0039] The mobile illumination rig can be utilized for a wide variety of crops including, but not limited to, those that may benefit from controlled photoperiodic responses. Such crops may include stevia; rice; chrysanthemums; spinach; potatoes; tomatoes; cotton; lettuce; soybeans; wheat; strawberries; cannabis; ornamental flowers; herbs (e.g., basil and cilantro); peppers; cucumbers; and others. These are just a few examples, and the mobile illumination rig could be adapted for use with many other types of crops that respond to changes in light exposure. The specific light requirements will vary depending on the plant species and desired outcomes, such as vegetative growth, flowering, or fruiting.
[0040] Referring now to the drawings, FIG. 1 shows a multitude of mobile illumination rigs 100a.. ,100c (collectively “mobile illumination rigs 100”) is a side-by-side arrangement that may navigate a field in a coordinated fashion. The mobile illumination rigs 100 may be described as being separate rigs (e.g., modular rigs) coupled to one another, or may be a single rig formed up of a multitude of same or similar rig sections.
[0041] Referring to a representative one of the mobile illumination rigs 100a (or mobile rig sections), generally referred to herein as the mobile illumination rig 100, the mobile illumination rig 100 includes a frame 102 that acts as a structure supporting various components, as will be described. The frame 102 generally includes a laterally extending member 105 connecting two frame ends 106a, 106b (collectively “frame ends 106”), where each frame end 106 can include a first vertical member 110a and a second vertical member 110b. The frame ends 106, including the first vertical member 110a and / or the second vertical member 110b thereof, position the laterally extending member 105 a predetermined height from the ground surface.
[0042] A coupling member 115 and / or the laterally extending member 105 connect the first vertical member 110a and the second vertical member 110b to one another to define an A-frame frame end 106 (or “A-frame end”). Thus, the laterally extending member 105 can connect two or more A-frames ends (or other frame ends 106) to one another. In some implementations, the first vertical member 110a may extend in a rearward direction relative to the laterally extending member 105, whereas the second vertical member 110b may extend in a forward direction relative to the laterally extending member 105. It is understood, however, that other support structure arrangements may be used without deviating from various aspects of the present disclosure.
[0043] The mobile illumination rig 100 includes a plurality of wheels 120 coupled to the frame 102. The wheels 120 facilitate the mobility of the rig across a field, enabling the mobile illumination rig 100 to navigate across the ground surface of the field. To this end, this mobility allows the mobile illumination rig 100 to traverse the field and illuminate the plants (not shown) planted therein, providing a uniform source of light to the plants. Operation of the wheels 120 can be performed by a controller 104, as will be described.
[0044] In some cases, the mobile illumination rig 100 is configured to traverse a field with crops planted in side-by-side rows, as can be appreciated. In some applications, the light-emitting panels 125 on the mobile illumination rig 100 may be arranged parallel to a ground surface and parallel to rows of crops such that the crops travel through a tunnel of light defined by various components of the mobile illumination rig 100, as will be described. This arrangement may facilitate a uniform distribution of light across the field, thereby providing a uniform source of light to the plants planted therein. Moreover, an irrigation or treatment system can apply water, fertilizer, growth chemicals, and so on, as predetermined for the crop. The mobility features of the mobile illumination rig 100 are particularly advantageous in large-scale commercial open fields where the mobile illumination rig 100 may be used to illuminate a large number of plants planted in rows.
[0045] In some cases, the wheels 120 may be designed to navigate across various types of ground surfaces 107, including but not limited to, uneven ground surfaces 107, sloping ground surfaces 107, or ground surfaces 107 with obstacles. The wheels 120 may be of any suitable type, including but not limited to, pneumatic wheels, solid rubber wheels, or plastic wheels. In some aspects, the wheels 120 may be configured to rotate in multiple directions to facilitate the movement of the mobile illumination rig 100 in various directions across the field. This may allow the mobile illumination rig 100 to navigate around obstacles in the field, or to follow a specific path or pattern across the field to ensure uniform illumination of the plants.
[0046] In some implementations, the mobile illumination rig 100 may include a drive module 121 coupled to the wheels 120 to drive the movement of the rig across the field, as can be appreciated. The drive module 121 may be any suitable type of drive mechanism, including but not limited to, a motor, a hydraulic drive system, an electrical drive system, or a mechanical drive system. The drive mechanism may be controlled by a controller 104 that is configured to control the operation of the drive mechanism by sending appropriatesignals (e.g., DC or AC signals) to the motors or other type of drive module 121 , and thereby control the movement of the mobile illumination rig 100 across the field.
[0047] The mobile illumination rig 100 includes a plurality of light-emitting panels 125. These light-emitting panels 125 are suspended from the laterally extending member 105, or other suitable component, via a plurality of suspension elements 140a...140d (collectively “suspension elements 140”) (FIGS. 1 and 12). In some implementations, the suspension elements 140 are stainless steel cables, chains, rope, electrical wires, or other suitable suspension elements.
[0048] In embodiments in which the suspension elements 140 are electrical wires, the electrical wires not just serve as suspension elements, but also electrically couple the lightemitting panels 125 to a controller 104 and at least one power source 109. This arrangement allows the controller 104 to control the operation of the light-emitting panels 125 and / or selectively provide power, varying the intensity and wavelength of the light emitted by the light-emitting panels 125. The suspension elements 125 can be coupled to the light-emitting panels 125 at respective comers to facilitate support of the light-emitting panels 125 during movement.
[0049] In some aspects, the controller 104 is configured to control the operation of the light-emitting panels 125 and the rotation of the wheels 120. This control allows for precise movement of the mobile illumination rig 100 across the field and accurate illumination of the plants. The controller 104 may be configured to control the wavelength at which the lightemitting panels 125. This allows for the adjustment of the light wavelength to suit the specific requirements of the plants in the field, which may vary based on a type of the plants in a particular row. In some cases, the wavelength at which the light-emitting panels 125 emit light is in a range between approximately 250 nm and approximately 800 nm. This range of wavelengths can cater to a wide variety of plants, each with their specific light requirements for optimum growth.
[0050] The light-emitting panels 125 are arranged in a manner that allows for uniform illumination of the plants in the field. The arrangement of the light-emitting panels 125 can be adjusted based on the specific requirements of the field and the plants therein. For instance, the light-emitting panels 125 can be arranged in a linear fashion as shown, a grid pattern, or other suitable arrangement. The arrangement of the light-emitting panels 125 can also be adjusted based on the size and shape of the field, the type of plants in the field, and other relevant factors. As previously indicated, the light-emitting panels 125 can includea plurality of LED light strips or other lighting affixed to a suitable substrate according to various embodiments.
[0051] In various embodiments, the mobile illumination rig 100 includes a reflective surface positioned above the plurality of light-emitting panels 125 relative to the ground surface. This reflective surface, referred to as a reflective sheath 130, may be arranged in a tented arrangement, as shown in FIG. 1 or a boxed arrangement, as shown in FIG. 12, as will be described. Generally, the reflective sheath 130 including a reflective surface designed to reflect light emitted by the light-emitting panels 125, thereby enhancing the uniformity of the light distribution across the field. The reflective sheath 130 may be formed of a reflective material, such as polyethylene terephthalate, biaxially-oriented polyethylene terephthalate, or like material. This material may be selected for its reflective properties, which can enhance the efficiency of the light distribution by the mobile illumination rig 100.
[0052] The tented or box arrangements of the reflective sheath 130 may be advantageous in providing a uniform arrangement of light that may promote better growth of the crops planted in the field. For the tented arrangement, an apex 170 of the reflective sheath 130, as shown in FIG. 2, denotes the peak or the topmost point of the tented arrangement. This apex 170 may be positioned directly above the light-emitting panel 125, or it may be offset to one side, depending on the specific design of the mobile illumination rig 100 and the lighting requirements of the field.
[0053] For embodiments in which the light-emitting panels 125 and / or the reflective sheath 130 are substantially level relative to the ground surface, the suspension elements 140 may each have an equal length. For instance, as shown in FIG. 12, three suspension elements 140 are suspending a light-emitting panel 125 and a reflective sheath 130 a predetermined distance from the ground surface, where the two suspension elements are substantially equal in length (e.g., ±1 %) with each having a fixed (not variable) length. The reflective sheath 130 has a coplanar top surface in contrast to the tented configuration. The length of the one or more suspension elements 140 may define the predetermined distance that the light-emitting panel 125 is positioned from the ground surface (and from a crop of variable height). In some embodiments, the light-emitting panels 125 are retained 0.25 m to 1.2 m off the ground surface, but other distances are within the present disclosure depending on the type of crop. For instance, some types of crops (e.g., com) are tall, requiring a shorter suspension element 140 such that the light-emitting panels 125 are retained higher from the ground surface.
[0054] In further embodiments, the mobile illumination rig 100 may include a wench (not shown) or like device configured to dynamically adjust a length of the one or more suspension elements 140. Thus, the controller 104 can programmatically raise or lower the light-emitting panels 125 relative to the ground surface. For instance, in some embodiments, the rows of crops planted in the field can have varying heights. The controller 104 can adjust the height of the light-emitting panels 125 based on a type of crop, a height measurement performed of an individual plant using a sensor, and so forth.
[0055] In some cases, the reflective sheath 130 includes a plurality of reflective sheath edges 135a, 135b (collectively “reflective sheath edges 135”) that extend downward from the sides of the light-emitting panels 125. These reflective sheath edges 135 further enhance the direction of light towards the crops planted in the field. The reflective sheath edges 135 may be configured to direct the light emitted by the light-emitting panels 125 towards the crops, thereby ensuring that the crops receive a sufficient amount of light for their growth. While not shown, in some embodiments, additional light-emitting panels or devices can be fixed along the reflective sheath edges 135.
[0056] The reflective sheath edges 135 may be formed of the same material as the reflective sheath 130, or they may be formed of a different material, depending on the specific requirements of the mobile illumination rig 100 and the field. Generally, the reflective sheath 130 (and / or the reflective sheath edges 135) define a tunnel 148 or channel through which plants are routed. As the mobile illumination rig 100 traverses a field, plants 149, such as crops, planted in a row sequentially transition through the tunnel, receiving a predetermined amount of light for a predetermined amount of time at a predetermined wavelength.
[0057] In some embodiments, the mobile illumination rig 100 includes one or more sprinklers 160a, 160b (collectively “sprinklers 160”) coupled to one or more hoses 161 a, 161 b (collectively “hoses 161”). The sprinklers 160 may include sprayer nozzles, as will be described. In some embodiments, the sprinklers 160 can be positioned at a front of the reflective sheath 130 as shown in FIG. 12; however, in other embodiments, the sprinklers 160 can be positioned through and in the middle of the reflective sheath 130, as shown in FIG. 1 (e.g., through an aperture in the middle of the reflective sheath 130), or potentially at the rear end of the reflective sheath 130 without impacting the light emitted within the sheath 30. The embodiment shown in FIG. 12 includes three suspension elements 140, where two hoses 161 are positioned between the three suspension elements 140. However, thedisclosure is not so limited, and other numbers of suspension elements 140, sprinkler 160, hoses 161 , and so forth can be employed.
[0058] The reflective sheath 130 and / or the reflective sheath edges 135 may extend a predetermined length S, which may refer to as a span of the reflective sheath 130 and / or the reflective sheath edges 135. In some embodiments, the predetermined length S is not less than 2.5 meters, although various predetermined span lengths can be employed.
[0059] Further, in some embodiments, the mobile illumination rig 100 includes a sensor arm 150 that extends outward from the frame 102. This sensor arm 150 may serve various monitoring or operational purposes. For instance, one or more sensors may be mounted on the sensor arm 150, which may be directed to the soil or crop planted therein. These sensors can be used to gather data about the field, the plants 149, or the environment, which may be fed back to the controller 104 to control operation of the mobile illumination rig 100. The data collected by these sensors can be used to adjust the operation of the mobile illumination rig 100, such as the intensity or wavelength of the light emitted by the light-emitting panels 125, the speed or direction of movement of the rig, an amount of time the mobile illumination rig 100 is positioned “on” a particular plant 149, and so on.
[0060] In some implementations, a sensor mounted on the sensor arm 150 can include an imaging device, such as a camera. The camera can include a red-green-blue (RGB) camera, an infrared camera, and so forth. This camera can be configured to capture images of the plants 149 planted in the field. These images can provide valuable information about the growth and health of the crops, the presence of pests or diseases, the moisture content of the soil, bloom amounts, and other relevant factors. Such information can be determined using convolutional neural network (CNN) artificial intelligence classification routines, other artificial intelligence classification and identification, manual inspection, and so on.
[0061] Such information can be used to adjust the operation of the mobile illumination rig 100 to optimize the growth and yield of the crops. In further embodiments, the sensor can include a spectrometer (e.g., a Ramen spectrometer), a crop sensor, a soil sensor, and so forth. The sensor arm 150 may be designed to extend outward relative to the frame 102. This outward extension of the sensor arm 150 can allow the sensor to cover a wider area of the field, thereby providing more comprehensive data about the field and the crops. The sensor arm 150 may be adjustable, allowing the position or orientation of the sensor to be adjusted as per the requirements of the field or the crops, as will be described.
[0062] In operation, the mobile illumination rig 100 navigates across a field, providing a uniform source of light to the plants 149 planted therein. This operation is facilitated by the controller 104 that controls the operation of the light-emitting panels 125 and the rotation of the wheels 120 (e.g., by driving a motor using step waves, current, and so forth). The controller 104 may be configured to control the intensity and wavelength of the light emitted by the light-emitting panels 125, thereby allowing for precise illumination of the plants 149. The controller 104 may also control the speed and direction of movement of the mobile illumination rig 100, thereby ensuring that the rig traverses the field in a manner that provides uniform illumination to the plants 149.
[0063] In some cases, the controller 104 may include a networking module 108, allowing the light-emitting panels 125 and the rotation of the wheels 120 to be directed remotely through network communications with the controller 104 (e.g., from a server or other computing device), which may be part of a general-purpose computing device, an application-specific integrated circuit (ASIC), a field-programmable gate array (FGPA) device, and so forth. This allows for remote operation of the mobile illumination rig 100, which can be particularly advantageous in large-scale commercial open fields where the rig may be used to illuminate a large number of plants 149 planted in rows. The networking module 108 may facilitate communication between the controller 104 and a remote control device, such as a computer, server, or a handheld device, thereby allowing an operator to remotely instruct, control, or direct the operation of the mobile illumination rig 100.
[0064] In some embodiments, the mobile illumination rig 100 may include an irrigation system traditionally employed with mobile irrigation rigs, which may include the sprinkler 160 that are fluidly coupled to hoses 161 for treating the plants 149 with water, fertilizer, and / or liquid treatment solutions. The controller 104 may thus be further configured to control an operation of the light-emitting panels 125, the sprinklers 160, and / or an operation of the wheels 120. This allows for integrated control of the illumination and irrigation operations of the mobile illumination rig 100.
[0065] For instance, the controller 104 may be configured to control the operation of the light-emitting panels 125 to provide the appropriate intensity and wavelength of light for the plants 149, while also controlling the operation of the sprinklers 160 to provide the appropriate amount of water for the plants 149. The controller 104 may also control the operation of the wheels 120 to ensure that the mobile illumination rig 100 navigates the field in a manner that provides uniform illumination and irrigation to the plants 149.
[0066] One of the operational parameters that the controller 104 may control is the wavelength at which the light-emitting panels 125 emit light. This allows for the adjustment of the light wavelength to suit the specific requirements of the plants 149 in the field. For instance, different types of plants 149 may require light of different wavelengths for optimum growth. By controlling the wavelength at which the light-emitting panels 125 emit light, the mobile illumination rig 100 can cater to a wide variety of plants 149, each with their specific light requirements.
[0067] In some cases, the wavelength at which the light-emitting panels 125 emit light is in a range between approximately 250 nm and approximately 800 nm. This range of wavelengths can cater to a wide variety of plants 149, each with their specific light requirements for optimum growth. For instance, some plants 149 may require light of a specific wavelength within the ultraviolet range (approximately 250 nm to 400 nm) for optimum growth, while others may require light of a specific wavelength within the visible light range (approximately 400 nm to 800 nm). By controlling the wavelength at which the light-emitting panels 125 emit light, the mobile illumination rig 100 can provide the appropriate light for each type of plant 149 in the field, thereby promoting better growth of the plants 149.
[0068] FIG. 1 includes callout region 2, shown in an enlarged manner in FIG. 2. Referring to FIG. 2, the light-emitting panel 125 is suspended beneath the laterally extending member 105 by suspension elements 140 which may be rigid elements (e.g., down-rods or like devices) or non-rigid, flexible elements (e.g., stainless steel cable, electrical wire, chains, and so on), or a combination thereof. The light-emitting panel 125, in conjunction with the reflective sheath 130 and the reflective sheath edges 135, provides a uniform arrangement of light that may promote better growth of the plants 149 planted in the field.
[0069] As shown in FIG. 2, the mobile illumination rig 100 includes a reflective sheath 130 positioned above the light-emitting panel 125 relative to the ground surface. The reflective sheath 130 is in a tented arrangement, with the apex 170 denoting the peak or the topmost point of the tented arrangement. This apex 170 may be positioned directly above the light-emitting panel 125, or it may be offset to one side, depending on the specific design of the mobile illumination rig 100 and the lighting requirements of the field.
[0070] In some cases, the reflective sheath 130 includes a plurality of reflective sheath edges 135 that extend downward from the sides of the light-emitting panels 125. Thesereflective sheath edges 135 further enhance the direction of light towards the plants 149 planted in the field. The reflective sheath edges 135 may be configured to direct the light emitted by the light-emitting panels 125 towards the crops, thereby ensuring that the crops receive a sufficient amount of light for their growth. The reflective sheath edges 135 may be formed of the same material as the reflective sheath 130, or they may be formed of a different material, depending on the specific requirements of the mobile illumination rig 100 and the field.
[0071] In various embodiments, the reflective sheath 130 may be formed of two sheath panels, namely a first sheath panel 165a and a second sheath panel 165b. These sheath panels 165a, 165b are arranged in a manner to form the tented configuration of the reflective sheath 130. For instance, the first sheath panel 165a includes an inner edge positioned at the apex 170 and coupled to the second sheath panel 165b at the apex 170. The first sheath panel 165a includes an outer edge positioned at a height less than the inner edge positioned at the apex 170.
[0072] Likewise, the second sheath panel 165b includes an inner edge positioned at the apex 170 and coupled to the first sheath panel 165a at the apex 170. The second sheath panel 165b includes an outer edge positioned at a height less than the inner edge positioned at the apex 170. The arrangement of the sheath panels 165a, 165b can be adjusted to optimize the reflection of light towards the plants 149 in the field. The sheath panels 165a, 165b may be separate panels, or may be integral with one another. In aspects where the sheath panels 165a, 165b are integral with one another, the tented arrangement may be created by forcing a bend in a central portion of an elongated panel, thereby defining the apex 170, and the sheath panels 165a, 165b.
[0073] In some implementations, a counterweight 155 is attached to the sensor arm 150. The counterweight 155 serves to balance the structure of the mobile illumination rig 100, particularly when the sensor arm 150 is extended outward. This balance can help to maintain the stability of the mobile illumination rig 100 as it navigates across the field, thereby ensuring that the illumination of the plants 149 is not disrupted by any instability of the rig.
[0074] As shown in FIG. 2, the sensor arm 150 includes a first sensor arm member 175 and a second sensor arm member 180. The first sensor arm member 175 and the second sensor arm member 175 can be substantially orthogonal with one another (e.g., ±15% of 90°). A distal end of the first sensor arm member 175 (e.g., proximal to the counterweight155) can be coupled to the frame 102 via one or more connection mechanisms, as can be appreciated, while permitting movement along the x axis shown in FIG. 2. The sensor arm members 175, 180 are connected to a sensor rail 185. The sensor rail 185 serves as a guide for the movement of the sensor arm 150, allowing the sensor arm 150 to move along the sensor rail 185 in a controlled manner along the y axis shown in FIG. 2. This controlled movement can help to ensure that the sensor arm 150 covers the desired area of the field, thereby providing comprehensive data about the field and the crops. In the embodiment of FIG. 2, the sensor rail 185 is a single rail, also referred to as a monorail. It is understood, however, that other numbers of rails can be employed. In some embodiments, the sensor rail 185 (or multiple sensor rails 185) has a length such that a single sensor can span use across multiple mobile illumination rigs 100, as shown in FIG. 1.
[0075] Referring again to FIG. 2, the sensor arm member 180 may include a sensor mount 190. Various types of sensors 192 may be configured to affix or otherwise couple to the sensor mount 190. The sensor mount 190 (or the second sensor arm member 180 affixed thereto) may be operable to move along the z axis, shown in FIG. 2. Thus, the sensor 192 (e.g., a camera) can be capable of movement along the x, y, and / or z axis. In some embodiments, the sensor arm members 175, 180, and / or the sensor mount 190, may be coupled to a motor, servo, or like device, such that movement of the sensor along the x, y, and / or z axis can be directed or controlled by the controller 104.
[0076] Turning next to FIG. 3, another embodiment of the mobile illumination rig 100 is shown according to various embodiments. Notably, FIG. 3 has the light-emitting panels 125, reflective sheath 130, and other components omitted for explanatory purposes. Generally, FIG. 3 shows an alternative arrangement of the sensor arm 150, also shown in callout region 4 shown in FIG. 4. Referring to FIGS. 3 and 4 collectively, instead of being positioned closer to the ground surface, the sensor arm 150 may be mounted above the laterally extending member 105.
[0077] To this end, the mobile illumination rig 100 may include a plurality of support posts 195 extending from a top of the laterally extending member 105. The sensor rail 185 may be positioned on top of the support posts 195, and may serve as a guide for the movement of the sensor arm 150, allowing the sensor arm 150 to move along the sensor rail 185 in a controlled manner along the y axis. Again, the sensor rail 185 is a single rail or monorail, and other arrangement can be provided.
[0078] Moving along to FIG. 5, another embodiment of the mobile illumination rig 100 is shown according to various embodiments. Like FIG. 3, FIG. 5 has the light-emitting panels 125, reflective sheath 130, and other components omitted for explanatory purposes. Generally, FIG. 5 shows another alternative arrangement of the sensor arm 150, also shown in callout region 6 better shown in FIG. 6. Referring to FIGS. 5 and 6 collectively, like the embodiment of FIGS. 3 and 4, instead of being positioned closer to the ground surface, the sensor arm 150 may be mounted above the laterally extending member 105, which may be desirable for varying types of sensors.
[0079] The mobile illumination rig 100 includes a plurality of support posts 195 extending from a top of the laterally extending member 105. Instead of being a single rail or monorail, the embodiment of FIGS. 5 and 6 include multiple sensor rails 185, collectively providing a sensor rail assembly that may be positioned on top of the support posts 195 that may serve as a guide for the movement of the sensor arm 150. Again, the sensor arm 150 may move along the sensor rails 185 in a controlled manner along the y axis.
[0080] As shown in FIG. 6, the sensor arm 150 includes multiple first sensor arm members 175, multiple second sensor arm members 180, and multiple sensor mounts 190. The first sensor arm members 175 and the second sensor arm members 180 can be substantially orthogonal with one another (e.g., ±15% of 90°). The sensor arm members 175, 180 are connected to sensor rails 185, which guide for the movement of the sensor arm 150, allowing the sensor arm 150 to move along the sensor rail 185 in a controlled manner along the y axis.
[0081] Moving along to FIG. 7, another embodiment of the mobile illumination rig 100 is shown according to various embodiments. Generally, FIG. 7 shows another alternative arrangement of the sensor arm 150, also shown in callout region 8 better shown in FIG. 8. Referring to FIGS. 7 and 8 collectively, instead of being positioned higher relative to the ground surface, the sensor arm 150 may be mounted below the laterally extending member 105, which may be desirable for varying types of sensors. However, the sensor arm 150 may still be positioned above the light-emitting panels 125 and / or the reflective sheath 130.
[0082] As shown in FIG. 8, the sensor arm 150 includes multiple first sensor arm members 175, multiple second sensor arm members 180, and multiple sensor mounts 190. The first sensor arm members 175 and the second sensor arm members 180 can be substantially orthogonal with one another (e.g., ±15% of 90°). The sensor arm members 175, 180 are connected to sensor rails 185, which guide for the movement of the sensorarm 150, allowing the sensor arm 150 to move along the sensor rail 185 in a controlled manner along the y axis.
[0083] Moving along, FIGS. 9 and 10 show front elevation views of the mobile illumination rigs 100, 100b, respectively. FIG. 9 specifically shows a sensor rail 185 having a length of approximately 15 m, whereas FIG. 10 shows a sensor rail 185 having a length of approximately 20 m. It is understood, however, that the length of the rail can vary depending on a desired application and the length of the sensor rail 185 can be, for example, 1 m, 2 m, 3 m, and so forth, and 21 m, 22 m, and so on. The sensor rail 185 can include a monorail, or can be multiple sensor rails 185, as described above.
[0084] Turning next to FIG. 11 , an example flowchart 200 is shown illustrating an example operation of the mobile illumination rig 100 according to various embodiments. Generally, the mobile illumination rig 100 can be operated in a manner that includes controlling a speed of the mobile illumination rig 100 and / or stopping over plants 149 for a predetermined amount of time or using sensor data to customize illumination for individual plants 149 or crops.
[0085] In some aspects, a method includes providing a mobile illumination rig 100 configured to traverse a field and provide a uniform source of light to plants 149 planted therein, where the mobile illumination rig 100 includes a controller 104, a plurality of wheels 120, and one or more light-emitting panels 125. The one or more light-emitting panels 125 are communicatively coupled to the controller 104 and at least one power source 110. The mobile illumination rig 100 can further include a reflective surface (e.g., a reflective sheath 130) positioned above the plurality of light-emitting panels 125 relative to the ground surface.
[0086] At 205, before operation, the mobile illumination rig 100 can be calibrated to recognize different plant species and their specific light requirements. This can include programming the controller 104 with parameters such as light intensity, wavelength, and duration of exposure for each crop type. Further, the mobile illumination rig 100 can be calibrated based on environmental conditions or a desired outcome (e.g., crop yield).
[0087] At 210, the mobile illumination rig 100 is deployed in the field and begins to traverse the rows of crops. In other words, the controller 104 can direct the mobile illumination rig 100 to position a plant 149 relative to a light-emitting panel 125 and the reflective surface, such as the reflective sheath 130. The wheels 120 and the frame 102 are designed to navigate the terrain while providing stability for the illumination and sensingsystems. In some embodiments, the mobile illumination rig 100 further includes a global positioning system (GPS) module for autonomous navigation within the field. The GPS module can be configured to work in conjunction with the controller 104 to follow predetermined paths between rows of crops.
[0088] At 215, as the mobile illumination rig 100 moves, sensors, such as camera, mounted on the sensor arm 150 collect data on plant health, growth stage, environmental conditions, and / or other data. This data may include visual imagery, temperature, humidity, and soil moisture levels.
[0089] Next, at 220, the controller 104 processes the sensor data in real-time to make decisions on illumination. For example, if the sensors detect a plant 149 that is not at the desired growth stage, the mobile illumination rig 100 may stop while the plant 149 is positioned underneath the light-emitting panel to provide additional light. Upon identifying a plant 149 or crop that requires illumination, the mobile illumination rig 100 stops and positions the light-emitting panels 125 directly above the target plant 149. The controller 104 then directs or activates the light-emitting panels 125 (if not already active) to provide the predetermined amount of light, for a predetermined duration, at a predetermined wavelength.
[0090] The predetermined amount of light, duration, and wavelength can be determined by the controller 104 as a function of the type of the plant 149, the stage of growth, growth parameters, soil characteristics, and so forth. For instance, the duration of the stop can be based on the specific light requirements of the plant 149. The mobile illumination rig 100 may remain stationary for a period ranging from a few seconds to several minutes to deliver the correct illumination treatment. In other words, at 220, the controller 104 may determine an illumination plan for a plant 149 based on at least one environmental condition associated with the plant 149 of a field in which the plant 149 is planted, wherein the illumination of the plant 149 can be performed in accordance with the illumination plan.
[0091] At 225, the controller 104 adjusts the light intensity, spectrum, and duration based on the sensor data and the requirements of the plant 149. This ensures that each plant 149 receives a customized light treatment for optimum growth or flowering. After delivering the light treatment, the mobile illumination rig 100 resumes its movement across the field to the next target area or plant 149. The process repeats, with the mobile illumination rig 100 potentially stopping (or moving at a controlled rate) and providing light as determined by the sensor data and programmed parameters. In some embodiments,the mobile illumination rig 100 can also be programmed to operate during nighttime hours, providing light treatments to control the photoperiodic response of the plants 149 or otherwise control growth of the plant 149. The controller 104 ensures that the plants 149 are not exposed to light for more than the desired number of hours.
[0092] Throughout the operation, the mobile illumination rig 100 continues to monitor the field using its sensors (192). The controller 104 can make adjustments to the illumination plan based on changes in environmental conditions or plant growth, ensuring that the light treatments remain effective and efficient. This method of operation allows for precise control over the light environment of each plant 149, potentially leading to improved crop yields, optimized growth, and the ability to induce or delay flowering as desired by the grower.
[0093] In some implementations, the light-emitting panels 125 may be configured to provide illumination that optimizes the performance of imaging sensors mounted on the sensor arm 150. For instance, when an RGB camera is employed as the sensor 192, the controller 104 may initially direct the light-emitting panels 125 to emit light in wavelengths that enhance the camera's ability to capture detailed visual information about the plant 149. Similarly, when an infrared camera is utilized, the light-emitting panels 125 may emit light in specific infrared wavelengths that facilitate optimal thermal imaging or near-infrared spectroscopy of the plant tissue. This coordinated illumination approach may allow the imaging devices to gather more accurate data regarding plant health, growth stage, chlorophyll content, water stress levels, and other physiological characteristics that might not be readily apparent under ambient lighting conditions.
[0094] Based on the characteristics inferred from the sensor data collected during this initial illumination phase, the controller 104 may subsequently adjust the wavelength output of the light-emitting panels 125 to provide targeted treatment illumination to the plant 149. For example, if the RGB camera detects signs of nutrient deficiency through leaf coloration analysis, the controller 104 may switch the light-emitting panels 125 to emit light in the blue or red spectrum ranges known to promote chlorophyll production and photosynthetic activity. Alternatively, if infrared imaging reveals areas of water stress or disease, the controller 104 may apply specific wavelengths that have been shown to enhance plant immune responses or improve water uptake efficiency. This two-phase approach of diagnostic illumination followed by therapeutic illumination may enable more precise andeffective plant treatment protocols tailored to the specific needs identified through sensor analysis.
[0095] Turning now to FIGS. 13-15, various front views of a mobile illumination rig 100 are shown having an irrigation system for irrigating plants 149 planted therein in accordance with various embodiments of the present disclosure. As noted above, the mobile illumination rig 100 may include an irrigation system in some embodiments. The irrigation system can include one or more sprinklers 160, hoses 161 , pressure regulators 162, nozzles, and so forth. The sprinklers 160 can include low energy, precise application sprinklers that deliver water approximately 0.20 m to 0.45 m above the ground to combat wind-drift and prevent evaporation loss. Twenty percent of water or more generally reaches the soil as compared to conventional spray nozzles. In some embodiments, the sprinklers 160 can include one or more nozzles, such as one nozzle, two nozzles, three nozzles, and so forth. The sprinklers 160 and / or the nozzles thereof can be configured to apply a predetermined water pattern between 0.1 m and 1 m relative to a plant to be irrigated. In some embodiments, the predetermined water pattern is applied substantially 0.61 m (e.g., ±10% 0.61 m) from the plant 149, as shown in FIGS. 13-15.
[0096] Referring to the embodiment of FIG. 13, the sprinkler 160 can include a wide spray bubbler with a shroud and a beige bubble insert that generates a water pattern WP shown in FIG. 13. A bubbler side of a deflector pad can gently deposit water onto a soil surface or plant 149 in a bubbling stream, in an aerated manner that resists wind and evaporation. The characteristics of the wide spray bubbler are shown in Table 1 below. The wide spray bubbler may prevent wind-drift fluid losses, may minimize evaporative loss, can avoid wetting plant canopy in row crops, can achieve a more uniform root zone coverage, can increase yield using less water, and so forth.Table 1
[0079] Referring to the embodiment of FIG. 14, the sprinkler 160 can include a wide spray bubbler with a shroud and a red CM1 deflector insert that generates a water pattern WP shown in FIG. 14. The characteristics of the wide spray bubbler are shown in Table 2 below. The wide spray bubbler may prevent wind-drift fluid losses, may minimizeevaporative loss, can avoid wetting plant canopy in row crops, can achieve a more uniform root zone coverage, can increase yield using less water, and so forth.Table 2
[0080] Referring to the embodiment of FIG. 15, the sprinkler 160 can include a bubbler pad assembly that generates a water pattern WP shown in FIG. 15. Like the foregoing wide spray bubblers, the bubbler pad assembly may prevent wind-drift fluid losses, may minimize evaporative loss, can avoid wetting plant canopy in row crops, can achieve a more uniform root zone coverage, can increase yield using less water, and so forth.
[0081] In some implementations, the sensor 192 may be positioned within the channel defined by the reflective sheath 130 and the reflective sheath edges 135, rather than being mounted ahead of the plant 149 on the sensor arm 150. This positioning may allow the sensor 192 to collect data while the plant 149 is actively receiving illumination treatment, providing real-time feedback on the plant's response to the light exposure. The sensor 192 positioned within the channel may be configured to monitor parameters such as leaf temperature, chlorophyll fluorescence, or photosynthetic activity during the illumination process, enabling the controller 104 to make immediate adjustments to light intensity, wavelength, or duration based on the plant's physiological responses.
[0082] In various embodiments, the mobile illumination rig 100 may employ a combination of sensor positioning strategies, utilizing both sensors mounted on the sensor arm 150 for preliminary assessment and sensors positioned within the reflective sheath 130 for treatment monitoring. The sensors on the sensor arm 150 may perform initial plant identification and health assessment as the mobile illumination rig 100 approaches each plant 149, while the sensors within the channel may provide continuous monitoring during the illumination treatment phase. This dual-sensor approach may enhance the precision of the illumination system by enabling both predictive treatment planning and real-time treatment optimization, potentially improving the effectiveness of the light therapy and reducing the risk of over-exposure or under-treatment of individual plants 149.
[0083] The features, structures, or characteristics described above may be combined in one or more embodiments in any suitable manner, and the features discussed in the variousembodiments may be interchangeable, if possible.
