Agricultural Lighting For Vine-Like Plants
A grow lighting system for use with vine-like plants includes an elongated body for positioning adjacent a plant. The body defines multiple channels or faces extending the length of the body for removably supporting linear grow lighting sources, such as grow lighting LED strips. The linear lighting sources are oriented to emit light radially outward from the fixture.
The present disclosure relates to indoor, greenhouse, agricultural and horticultural plant growing, and more specifically, to such lighting for vine-like plants.
For a more complete understanding of the features and advantages of the present invention, reference is now made to the detailed description of the invention along with the accompanying figures in which corresponding numerals in the different figures refer to corresponding parts and in which:

Indoor, greenhouse agricultural growing of Humulus lupulus has become more common, but presents unique challenges. Humulus lupulus produces hops, or hops flowers, widely used in manufacture of food items. The indoor grow of hops allows for growing of hops flowers outside a very specific temperate climate where currently all hops are grown. Humulus lupulus plants present unique infrastructure requirements for an indoor environment where plants must be close in proximity in order to grow enough yield of hops flowers to achieve an economic yield. Hops plants are full grown at around twenty feet tall and are vine-like spreading plants. The close proximity required for economic yields produces challenges in providing each plant with enough light to allow the plants to reach their mature height. The upper reaches of the larger plants reduce or eliminate sufficient light from reaching the lower parts of the vines and negatively effects plant growth. This is the case whether the greenhouse utilizes natural light from overhead windows or overhead lighting.
A customizable lighting system is presented for use in the growth of Humulus lupulus plants, and other plants with similar growth patterns or presenting similar problems with sufficient lighting at lower levels, in a controlled greenhouse environment. Supplementary lighting, in the form of vertically installed lighting, provides light coverage along the height of the plant, including particularly at lower levels. The orientation of the lighting fixtures can be easily adjusted, varied or removed to accommodate changing requirements as the plants grow.
The present disclosure utilizes a non-metallic extruded channel design to hold multiple, independent, linear lighting sources. The lighting sources, when installed in the device, provide light over a long enough to extent to provide light over the height of the plants. Further, the lighting sources attached to the fixture provide light emission across 360 degrees around the fixtures, allowing for light provision to plants positioned at any point around the fixture.
The lighting fixture 10 is an extruded, linear, non-metallic product and does not require heat dissipation. The fixture 10 defines a longitudinally extending body 30. The body 30 can take various forms. For example, in
The fixture 10 includes a plurality of vertical lighting channels 12 designed to hold a plurality of linear lighting sources 14. The channels 12 define an interior passageway 16 for housing the lighting sources. The channel 12 can comprise, for example, longitudinal side walls 18, a back wall 20, and, optionally, flanges 22. In some embodiments, part or all of the back wall 20 of a channel 12 also serves as a side wall 32 of the body 30, as seen in
The channel 12 is sized to accept and hold a longitudinally extending lighting source. The channels 12 are designed to allow the lighting sources to be slid into, pressed into, or snapped into a fixed position in the channel interior passageway 16. In some embodiments, the light sources are friction fit into the channels. In other embodiments, the light sources are maintained in position in the channels by flanges 22, which can take the form of longitudinal flanges running substantially the length of the fixture or can be a plurality of shorter flange tabs spaced apart along the channel. Alternately, other attachment mechanisms can be used to attach and maintain the lighting sources in the channel. For example, strip lighting is available having adhesive backing, allowing the lighting sources to be adhered to the channel back wall.
The channels 12 are oriented to position the lighting sources 14 such that the lights 24 along the lighting source 14 emit light radially outwardly from the fixture. A plurality of lighting channels are oriented to position the lighting strips to emit light across a wide radial range about the fixture. For example, in
The lighting fixtures 10 and lighting channels 12 are sufficiently long to provide lighting along substantially the entire length of the plant, thereby providing light to encourage plant growth along the entire height of the plants. In an embodiment, the fixtures are 16 feet long; in other embodiments, the fixtures are 20 feet long. Extrusion manufacturing allows for ease of creating lengthy fixtures and fixtures of any selected length. The elongated fixture 10 can be formed of multiple pieces joined together, such as by snap-fit, friction fit, adhesive, etc., allowing for ease of packaging, transport and assembly.
The lighting source 14 can include a plurality of individual lights 24, such as LED lights along a longitudinal LED lighting strip or module. The lighting source 14 can take various forms. LED lighting strips, with or without adhesive backing, can be used. For example, the lighting source can be lighting strips or lighting modules such as are commercially available. Lighting modules have spaced apart, stiff circuit boards, each board typically having one to three light sources, the boards connected by intervening wires. Further, the lighting source can be a single color or color-changing sources which allow for color-changing as well as white. The LED lighting strips preferably have lights specifically designed to provide light for plants and to promote plant growth. For example, LED lights can provide red, blue, white, UV, etc., light at various stages of plant growth, such as at seeding, for vegetative growth, blooming, and overall health of the plant. Since the plants' light needs may change over the plants' life, a color changing LED strip can be used and the emitted light changed over the plant's life. Various spectrum lighting can be supplied, such as one or a mixture of the following: red 630-660 nm, blue at around 460 nm, white 6000-6500 k, UV 380-400 nm, IR 730-740 nm, etc. Lighting strips can be used having various lengths. For example, for a 20 foot fixture length, a 20 foot LED strip can be used. Alternately, shorter lengths can be used and connected end-to-end at strip connectors. Further, LED strip lighting is available for use with a controller which can operate the LED lights on the strip individually. Hence, it is possible to control the lights such that only lights adjacent the plants are on (e.g., the lower lights while the plant is short) to reduce electricity costs. Further, it would be possible to tune each light to a selected frequency (e.g., UV, white, red, etc.) based on the needs of the plant.
The power supply can be a wall socket, batteries, generators, etc. In some instances, the heat generated by the power supplies is an issue as the heat may damage or negatively effect growth of the plants. Consequently, it may be desirable to position the power sources spaced from the plants and provide electric cable connections from the remote sources to the fixtures.
In some embodiments where multiple plants are grown from the same pot, each lighting source can correspond to a vine-like plant, the lighting sources positioned to orient light emitted from the lighting sources towards each of the corresponding plants. For example, each lighting channel can correspond to a vine-like plant, the lighting channels positioned to orient light emitted from the plurality of corresponding lighting sources towards each of the corresponding plants.
