Description

Illumination system for plant growth and development

Technical Field

The invention relates to the technical field of plant growth and cultivation, in particular to an illumination system for influencing the growth and development of plants based on cloud computing plant growth factors.

Background

Light plays an important role in plant growth and development, such as photosynthesis and photomorphogenesis. In horticulture, there are many applications, such as laboratories, greenhouses, urban/multi-farm plants, which propagate plant seedlings, tissue cultures, vegetables, flowers or plants with specific health benefits.

Plant tissue cultures are widely used to produce clonal plants by a process known as micropropagation. In this process, plant cells, tissues or organs are grown under sterile conditions on nutrient media of known composition.

Stages of tissue culture may include, but are not limited to, inoculation, apical shoots, propagation, acceleration, rooting, hardening. Tissue culture requires a growth medium containing nutrients for development, as well as light to support plant processes (e.g., photosynthesis). As shown in fig. 1, an illustrative example of a banana tissue culture process.

Other micropropagation methods include the use of seedlings, in which young plants will develop plant embryos from seeds. The stage of seedling may include, but is not limited to, germination, rooting, stretching/elongation, leaf orientation and shape, branching and lateral shoots. As shown in fig. 2, is an illustrative example of a seedling process. The early stage is part of the plant morphogenesis process. These plants, obtained from tissue cultures or seedlings, can be used in horticulture, which has been defined as plant agriculture, mainly for food, materials, comfort and aesthetics.

When a grower grows a plant tissue culture, certain aspects of tissue culture development may be preferred, such as, for example, propagation coefficient, number of rhizomes, number of leaves, meristem thickness, and biomass. These qualities determine the efficiency of the growth process, the quality of the plant, and the final yield on site or in the greenhouse.

The plants need light and CO₂、H₂O and some nutrients to support the photosynthesis process that allows the plant to grow. As shown in fig. 3, is an illustrative example of a photosynthesis process in nature.

In the daytime, plants utilize natural light, CO₂、H₂O and soil nutrients to make sugars that support growth. The amount of light is expressed in micromolar (. mu.mol/s). However, the spectrum is expressed in nanometers (nm). Measured, the spectrum of the light required by the plantTypically in the range of 400nm to 700nm or 350nm to 800 nm. In some cases, the nano-components are grouped into bands, such as 401nm to 500nm, 501nm to 600nm, and so forth. Other aspects describe color types such as blue, green, yellow, orange, red. Adjectives such as royal blue to indicate a darker blue color, or deep red and far red may be added to distinguish from ordinary blue and red colors.

Traditionally, artificial light close to natural daylight can be utilized as supplemental light to improve yield. Other examples of uses include photoperiod lighting to adjust the timing of flowering or cultivation without the need for lighting at urban farms and tissue culture laboratories. The latter is commonly applied in indoor and fully climate controlled environments.

Current applications include stationary devices with a fixed spectrum. Typically blue, red, far red or white. Typically, a plurality of light sources are mounted above, between, or around a plant so that there is sufficient light energy to illuminate the plant.

As disclosed in patent application 201710757927.3, a system and method for controlling the illumination of a plant, the system comprising: the device comprises a first detection assembly, a main controller and a first plant light supplement lamp connected with the main controller; the first detection assembly comprises a first illumination sensor and a first microcontroller connected with the first illumination sensor; the first microcontroller is connected with the main controller. The light intensity of the point to be measured is detected by the light sensor, the light intensity data are sent to the microcontroller, the microcontroller sends the light intensity data to the main controller, and the plant light supplement lamp is controlled by the main controller to adjust the light intensity, so that the light intensity of the point to be measured is controlled, the photosynthesis is guaranteed to reach the fastest speed, and waste is avoided.

However, although the patent application can realize the control of the illumination, the application is only limited to the control of the illumination, the function is single, and the control circuit is composed of two stages of controllers, so the application is quite complex and not practical; more importantly, the intelligent control of the plant growth can not be realized, and the promotion requirement of the plant growth can not be met.

The user is linked to a cloud server through a UI device, which in turn controls actuators through a gateway, under which the actuators are embodied as drivers and light sources, including but not limited to carbon arc lamps, incandescent lamps, low pressure sodium lamps, high pressure sodium lamps, L ED lamps.

Usually, a driver and at least one light source form an actuator, that is, an actuator comprises a driver and a plurality of light sources, so as to realize multi-angle illumination and uniform illumination of plants. The light sources may be connected in series or in parallel.

Fig. 6 is a schematic diagram of a specific application scenario of the present invention, in this implementation manner, wireless transmission is used as a transmission means of a control instruction, at a specific application end, a plant 2 is cultivated in a greenhouse 1, the plant is illuminated by a light source 3, the light source 3 is channeled by a driver 4, the control instruction is received by a local wifi 5 and transmitted to the driver 4, and a UI interface 7 sends the control instruction to the driver 4 through a gateway 6.

In short, the control of the lighting system can be realized in both a wired mode and a wireless mode.

For the light sources 3, the lighting system may be formed with different L ED or different sized L ED mounted on one fixture each may include a plurality of L ED sections per light source grouped by section or ungrouped each light source, the plurality of L ED sections including plant sensitive light between the 350nm to 850nm region, such as red, green, blue, white, orange, far red, ultraviolet.

The lighting system includes control means and methods to allow intensity adjustment of the L ED sections to adjust the spectrum from off to full on through an infinite number of steps and variables, such that each L ED section emits light at an intensity and color according to a predetermined or increasing lighting pattern that affects the PFD.

The illumination system may produce different light periods of continuous illumination periods during 24h cycles or intermittent illumination, including short flashes of 1 flash per millisecond.

The illumination system may reproduce a plurality of illumination ratios between 380nm and 780nm, wherein these ratios may be grouped into a single nanometer or a nanometer band up to the whole hundred nanometers closest thereto, such as 380 to 400, 401 to 500, 501 to 600, 601 to 700, 701 to 800. The illumination system may adjust the illumination.

Thus, the lighting system implemented by the present invention can utilize multiple single color or full spectrum L EDs and electromagnetic wavelengths to generate a new light pattern that supports a particular yield in plant growth and development L ED can be either single color spectrum or broad spectrum functionally, as shown in FIG. 8, is a schematic of five different light sensitivities, approximately single color L ED and one full spectrum L ED, which can utilize multiple single color or full spectrum L ED and electromagnetic wavelengths to generate a new light pattern that supports a particular yield in plant growth and development.

The light source is specifically realized as a L ED linear device formed by connecting a plurality of L ED sections, the L ED linear device of the L ED sections is in a straight shape, the straight shape has certain flexibility and can become flexible after being bent under certain conditions, the L ED linear device is in a strip shape, and L ED linear devices which can be in a single row are connected in series in the L ED linear device of the strip, but the light source can also comprise a plurality of L ED sections which are adjacent to each other in two rows, three rows or multiple rows.

For example, to trigger flowering, the spectral pattern may be re-modeled such that it simulates plant pigments pfr responsible for plant morphology, to support plant growth and density, the lighting may be re-modeled such that it supports chlorophyll a and b that contributes to compact growth.

At the same time, L ED light algorithm can be used to control the tissue culture propagation, rooting, germination, morphology method, the L ED light algorithm in time dynamically changes according to the target and growth stage of the plant during the growth process.

Likewise, the present invention can be used to promote or inhibit flower flowering in both long-and short-day plants by utilizing lighting algorithms that can trigger or delay flowering until a particular physical appearance of the plant is achieved, or until a desired time of year, or trigger or delay flowering according to another set of preferences set by the grower.

L ED illumination algorithms may be continuously adjusted so that certain nanometer wavelengths of light conform to the light algorithms of various growth processes if input is provided by other systems or by the end user via a user interface or controller, the system is able to model and re-model spectral values from time to time, as shown in FIG. 10.

The system may reproduce a natural spectrum based on input from an end user or API, as shown in fig. 11. For example, an exemplary natural spectrum that can be reproduced by a lighting system, thereby demonstrating that the system can mimic the optimal natural lighting conditions for areas within which certain plants flower or fruit in the best possible manner.

Other parameters in the light algorithm may include, but are not limited to, light intensity, light/dark cycles within a defined schedule, light summation over time, time of turn on and off, ratio of nanometer wavelength bands, distribution of light on a plant or tissue culture.

This enables the illumination to provide the plant needs precisely at each time and growth stage. The illumination system may process at least 40 commands per pixel per second. Each illumination system comprises at least 1 to an infinite number of pixels.

The ratio of the spectral bands can be controlled to an infinite number of possibilities within the electromagnetic spectrum. The spectrum of light in the present invention can be defined as a single nanometer band to hundreds of bands. For example, 10% from 300nm to 400nm, 90% from 401nm to 500nm, and so on. Based on the control input, the ratio can be dynamically adjusted to a target value, and the adjustment of the ratio is various and is realized according to the requirements of users and the plant cultivation requirements.

Based on a schedule or based on an algorithm and/or in cooperation with sensors of sunlight and actual plant quality, the lighting system may operate continuously or at regular intervals to readjust lighting and support growth and development of the plant. Fig. 13 is a schematic diagram of the light schedule and the interval lighting, in which the dark part is the lighting time.

The lighting system and method has some way to affect the timing of the plant, thereby affecting the growth of the plant as well as flowering or fruiting. Referring to fig. 14, which is an illustrative example of photoperiod control of short-day to long-day plants, it is apparent that the effect of light on flowering induction is different for short-day and long-day plants.

The lighting system may utilize the input of sensors and actuators to measure the plant height for optimal flowering time; once the plant reaches a certain height, the light will be turned on at night to induce or delay the flowering cycle. For example, as shown in fig. 15, flowering time management using light can be performed.

The lighting algorithm may be effective under certain boundary conditions including, but not limited to, temperature, CO2, water quality, growth medium, nutrients, plant hormones, and the like.

The illumination system may be adapted for, but not limited to, a specific kind/variety, a specific growth stage and growth method.

The illumination device may be mounted with a fixture at a suitable distance from the intended application so that the light can reach the intended plant or tissue culture. For example, for a tomato plant, a combination of top lighting and interior lighting may be used. For green walls, a combination of up lighting and down lighting may be used to create a wall wash or wipe effect. For tissue culture shelves, lighting devices may be installed or embedded to provide overhead lighting.

The fixture or individual light source or groups of light sources may include lenses or optics that project light at a particular angle and intensity. Such as, but not limited to, a small beam, a large beam, a wide beam, an extremely wide beam, an elliptical beam, an extremely large beam, a wide batwing, a batwing, asymmetric, area, diffuse asymmetric, single-sided asymmetric, and the like. However, the effect of these beam shapes is to achieve μmol horizontally and/or vertically to meet the illumination requirements.

The lighting system controls lighting using a method of controlling lighting in an 8-bit, 16-bit, or 32-bit manner so that it is effective for plants.

The lighting system may utilize multiple light sources, which may be generally linear, circular, or any other shape or combination of physical dimensions the L ED control circuit diagram of the lighting system is shown in FIG. 16.

In summary, the present invention has the following effects:
