Description

Lighting system used in plant growing environments

The disclosure relates to an illumination system used in indoor planting and a control method thereof.

Light is an important factor in the growth of plants, so artificial light can be used to improve the efficiency of plant energy use. For light-sensitive plants, the growth pattern, flowering fruit production period and fruit quality can also be upgraded through the regulation of light quality, light quantity and photoperiod.

Light is not only the energy of photosynthesis in higher plants, but also a signal for regulating important activities of plants such as light-type formation and photoperiod response. Among them, the light type construction refers to the phenomenon or process of light intensity, light quality, illumination time and spatial distribution of light affecting plant type occurrence. In its life cycle, plants optimize their growth and development to adapt to the changing light environment mainly through sensitizing pigments, cryptochromes and photoluminescence, such as light intensity, light quality and light direction.

During the development of chloroplasts, phytochrome, cryptochrome, protophyll chlorophyllin and chlorophyll are involved in the regulation of chloroplast development. Photosensitive pigments mainly feel red Light and infrared light also experience blue light and ultraviolet light. The cryptochrome dyes blue light and ultraviolet light, and ultraviolet light can also be used as a light source for killing bacteria, for example, to kill airborne bacteria or plant pathogens and pests. Many studies have shown that the development of photosynthetic organs is regulated by light for a long time. Red light is essential for the normal development of photosynthetic organs. It can increase the starch accumulation of leaves by inhibiting the output of photosynthetic products from leaves. On the other hand, blue light regulates physiological processes such as chlorophyll formation, chloroplast development and stomatal opening, and photosynthetic rhythm.

Therefore, it is an important issue to develop an illumination system that is suitable for assisting plant growth and making the output and quality of agricultural products conform to expectations.

Referring to Figure 11A, an embodiment of a solar-powered greenhouse application scenario is illustrated. In this embodiment, the plant 50 can be planted in a greenhouse 60, wherein the greenhouse 60 is, for example, a plastic film greenhouse or a glasshouse. Here, the greenhouse 60 can be considered as a plant cultivation that can be used to define a certain space for planting the plants 50 indoors. At the same time, the light L provided by the light source module 200 is used to illuminate the plant 50, and the light source module 20 can be controlled by the electronic control system 300 described in the foregoing embodiment. The electronic control system 300 regulates at least one of the growth form, the yield and the quality of the plant by regulating the optical parameters and the illumination period of the light L emitted by the light source module 200. That is to say, in the present embodiment, the illumination system formed by the light source module 200 and the electronic control system 300 is installed in the greenhouse 60 to provide the light environment required for the plant 50 to be planted.

In this embodiment, the illumination control method used in the greenhouse 60 includes separately controlling the amount of light emitted by the light-emitting elements of the light source module 200 by using the electronic control system 300 in various light environment context modes, and adjusting the emitted light source module 200. The optical parameters of the light L are at least one of the growth morphology, yield, and quality of the plant 50. Plant 50 will change with the whole plant growth or planting environment during different growth stages, and the light demand will be adjusted accordingly to facilitate the optimal physiological development of the plant. Therefore, the amount of illuminating light of at least some of the light-emitting elements in the light source module 200 is different in at least two of the light environment context modes, and the light 50 emitting different optical parameters is used to illuminate the plant 50 to regulate the growth of the plant 50. In addition, the illumination time is also one of the important factors affecting the growth of the plant 50. Therefore, the various light environment context modes described in this embodiment include the lighting period of the light source module 200 every day, and the amount of light emitted by the light emitting elements of the light source module 200 during the lighting period.

It can be seen from the foregoing embodiment that the electronic control system 300 includes a light source module control unit 310 for controlling the amount of light emitted by the light emitting elements, and a time domain control unit 320 for adjusting the light emitting period. In this way, by the adjustment control of the light source module control unit 310 and the time domain control unit 320, the light source L provided by the light source module 200 according to different light environment context modes can regulate the growth pattern and yield of the whole plant and the fruit of the plant 50. At least one of quality and suppression of pests and diseases, wherein the quality includes, for example, at least one of the appearance, color, aroma, mouthfeel, softness, and functional component content of the whole plant.

Here, the specific parameter conditions of the light environment context mode can be determined in various ways. In an embodiment, multiple sets of light environment context patterns may be pre-established in the electronic control system 300. When the electronic control system 300 has the architecture of any of Figures 1, 5, 6, 7, and 8, the memory database unit 360 stores a data D1, which includes the optical parameters required by the plant at various stages of growth. Relevant information such as the corresponding lighting period. When the electronic control system 300 stores multiple sets of established light environment situation patterns When the illumination system can determine the set of light environment context patterns to be illuminated according to the data D1 stored in the memory database unit 360. However, the electronic control system 300 may also control the light source module 200 not according to a predetermined plurality of sets of light environment context modes. That is to say, the electronic control system 300 can control and adjust the lighting conditions of the light source module 200 depending on the actual growth stage of the plant 50 or the actual growth condition caused by the change of the planting environment.

Here, the so-called growth stage can be divided according to the actual growth process of the plant 50, and includes, for example, a budding stage, a plant growth stage, a flowering stage, a fruiting stage, a fruit ripening stage, and the like. In addition, the growth stage can also be defined based on general planting experience. At this time, the growth stage can be based on at least the planting stage, the fertilization stage, the weeding stage, the pest and disease stage, and the multiple collection stages. In the acquisition phase, the acquisition phase can be divided according to monthly or seasonal variations, so different acquisition phases are not necessarily directly related to the actual growth phase of plant 50. For example, when plant 50 has three collection stages per year, the fruit collected in the second collection stage is not necessarily the fruit of the second result of the plant, and the fruit collected in the third collection stage is not necessarily the plant. The fruit of the third result. That is to say, the division of the growth stage can be artificial, rather than divided according to the actual growth situation.

Further, changes in the planting environment often result in physiological changes in the actual growth process. For example, during certain periods of the planting period, the overall physiological type of the plant will be further caused by changes in the temperature of the greenhouse planting environment or the temperature, humidity or soil pH in the soil, or due to factors such as pests and diseases. The state changes in difference. As a result, the unintended variables of the planting environment due to human or non-human factors will cause the original planting management method not to be applicable or to achieve the best efficiency. Therefore, in the embodiments of the present invention, the illumination parameters of the planting environment can be adjusted according to the actual growth physiological condition of the plant and the parameters of the temperature and humidity of the planting environment in each growth stage, so that the plant can reach the optimal growth condition.

In the architecture of FIG. 1, 5 and 8, the optical environment control unit 350 of the electronic control system 300 can determine the desired optical environment context mode according to the data D1 in the memory database unit 360 and the signal S1 of the time domain control unit 320. The light environment context mode may include an illumination period of the light source module 200 and an optical parameter of the light L emitted by the light source module 200 during the illumination period. The signal S2 related to the light environment context mode can be input to the light source control module unit 310, and then the light source control module unit 310 outputs the corresponding signal S3 to actually adjust the points of the respective light-emitting elements (201-205) in the light source module 200. Bright way. In this way, the light source module 200 can emit light according to the existing data. When the electronic control system 300 has established a plurality of sets of predetermined light environment context modes, the electronic control system 300 may select a suitable one of the plurality of sets of light environment context modes to control the light source module 200.

However, in other embodiments, as shown in FIG. 6 and FIG. 7 , the planting environment sensing unit 330 and the plant sensing analysis unit 340 may be further disposed in the electronic control system 300 . The electronic control system 300 can determine or select the desired light environment context mode by using the data actually measured by the two units together with the existing data D1. That is to say, the actual content of the data D1 will change with the information of the signal S4 and the signal S5. That is, the plant sensing analysis unit 340 measures the actual growth of the plant 50. After the shape, the light environment control unit 350 can determine the optical parameters and the lighting period of the light L required by the current growth situation of the plant 50, thereby determining the specific parameters of the light environment context mode. In the architecture of FIG. 6 and FIG. 7, the illumination system not only operates the light source module 200 according to the stored data D1, but also adjusts the illumination of the light source module 200 according to the actual plant 50 growth situation and actual environmental conditions.

The specific light environment context mode can be determined based on the type of plant 50. For example, as illustrated in FIG. 1 and FIG. 11A, in the present embodiment, the plant 50 is exemplified by a strawberry plant. The electronic control system 300 can automatically turn on the ultraviolet light emitting element 201, the red light emitting element 202, the green light emitting element 203, the blue light emitting element 204, and the infrared light emitting element 205 at 17 o'clock every day, wherein the light emitting element 209 provides Among the five colors of light output energy, for example, the light output energy is such that ultraviolet light, blue light, and green light are output in a small proportion of light quality (for example, a relatively small proportion of light intensity in the five light output energies). The ratios are, for example, 1.6%, 1.9%, and 1.3%, respectively; and the red light and the infrared light are output, for example, at a high ratio of light quality (for example, a relatively strong ratio of light in the five light output energies), The ratios are, for example, 27.4% and 67.8%, respectively. At 21 o'clock in the evening, the electronic control system 300 automatically turns off the ultraviolet light emitting element 201, the red light emitting element 202, the green light emitting element 203, the blue light emitting element 204, and the infrared light emitting element 205. In addition, the electronic control system 300 can determine the light quality and the amount of light of the five light sources according to the daylight illumination parameters and other environmental parameters detected by the planting environment sensing unit 330. The above-mentioned light quality ratio can achieve the effect of increasing strawberry fruit yield, increasing fruit size and increasing fruit coloration. In addition, in order to achieve such an effect, the electronic control system 300 can be configured by a plurality of predetermined light environment context modes. A suitable light environment context mode is selected to provide light that is close to or of the same quality of light and light to illuminate the plant 50.

During the fruit ripening period, the electronic control system 300 of the embodiment can regulate the output energy of the light L emitted by the light source module 200 to have a higher proportion of infrared light, blue light and red light, the proportion of which is, for example, 61.3%, respectively. 19.0%, 12.8%, and a small proportion of ultraviolet light and green light, the ratio is, for example, 3.5%, 3.4%. In this way, the fructose, glucose, sucrose and total sugar content of the strawberry can be increased to increase the sweet taste. Of course, in order to achieve such an effect, the electronic control system 300 can illuminate the plant 50 by selecting a suitable light environment context mode from a plurality of established light environment context modes to provide light of a near or the same quality of light and light.

In addition, the electronic control system 300 of the embodiment can also regulate the light L emitted by the light source module 200 such that the output energy has a relatively high proportion of near-infrared light, blue light, and red light, and the ratios thereof are, for example, 61.3%, 19.0%, respectively. 12.8%, and a small proportion of ultraviolet light and green light, the ratio is, for example, 3.5%, 3.4%. In this way, the total acid and citric acid content of the strawberry fruit can be increased to increase the acidity taste. If you want to increase the content of malic acid and oxalic acid, the light output ratio is 3.3% ultraviolet light, 11.1% blue light, 21.4% green light, 9.6% red light and 54.6% infrared light. Similarly, in order to achieve the desired result, the electronic control system 300 can select a suitable light environment context mode from a plurality of sets of predetermined light environment context modes to provide near or the same light quality and light quantity to illuminate the plant 50. .

In addition, the electronic control system 300 of the embodiment can also regulate the output energy of the light L emitted by the light source module 200 to have a relatively high proportion of infrared light, red light, and green light. The ratios are, for example, 46.8%, 21.2%, 20.6%, respectively, having a medium proportion of blue light, for example 8.5%, and having a small proportion of ultraviolet light, for example 2.9%. This increases the anthocyanin content of the strawberry. In order to achieve such an effect, the electronic control system 300 can illuminate the plant 50 by selecting a suitable light environment context mode from a predetermined plurality of sets of light environment context modes to provide near or the same light quality and quantity of light.

Furthermore, in the fruit ripening period or the full red period, the electronic control system 300 of the embodiment can also regulate the output energy of the light L emitted by the light source module 200 to have a higher proportion of infrared light, blue light and red light. The ratios are, for example, 61.3%, 19.0%, 12.8%, respectively, and have a small proportion of ultraviolet light and green light, the ratios of which are, for example, 3.5% and 3.4%, respectively, which can increase the phenolic substance and flavonoid content of the strawberry. In order to achieve such an effect, the electronic control system 300 can select a suitable light environment context mode from a plurality of predetermined light environment context modes to provide near or the same light quality and light quantity ratio. The illumination period of any of the above light environment context modes can be determined based on the growth requirements of the plant 50. Therefore, the lighting periods of different light environment situation modes can be the same or different, and there is no need to limit the interval of the passage from 17 o'clock to 21 o'clock in the evening.

Different light environment context patterns can alter the growth of plant 50 to give plant 50 different characteristics. Therefore, the user can adjust the illumination mode according to the expected effect, and even change the specific conditions of the light environment context mode according to plant growth or according to planting experience. In general, the growth of plant 50 takes several days, weeks to months, so each light environment context pattern can last for several days to several months. In other words, every day in a few days or months The light source module 200 is activated in accordance with the selected light environment context mode. However, it is not limited to this. In other embodiments, the light source module 200 can be operated in the same light environment context mode for many days, optionally in days or months, without having to operate in the same light environment context mode every day.

Specifically, depending on the planting conditions and situational requirements, the conditions required to grow the light environment will be different. Therefore, the lighting system can be designed with different light output to achieve the best energy saving effect and lower cost, so the light source The number of light-emitting elements actually required by the module 200 can be increased or decreased depending on the required light quality and amount of light, and the position of each light-emitting element is also configured to optimally mix light with the total number of light-emitting elements. Although the number of each light-emitting component may vary according to actual light conditions, the ratio of the light intensity output ratio of the light source module 200 may be considered to consider the type of the plant and the optimal light environment characteristics of the plant (for example, light). Compensation point and light saturation point, carbon dioxide and light exchange influence parameters, temperature and humidity and light interaction parameters, soil nutrient and light interaction parameters, illuminance demand, etc.), actual planting environment conditions (such as planting indoors and outdoors, with or without sunshine, The amount of sunshine, the light quality and light quantity of the planting environment, the space of the planting environment and the temperature and humidity of the soil, the pH of the soil, the soil nutrient, the climate temperature and humidity of the planting site, the pest and disease hazard, etc.), the actual growth of the plant (such as the number of new leaves, leaflets) Length, leaflet width, petiole length, leaf area, chlorophyll, stem crown thick, peduncle length, flower stem diameter, number of flowers, fruit turn red, total fruit, hardness, sugar content, fruit length, fruit width, fruit number, pests, color , the content of various functional components, etc.), the time when the light source is turned on (such as evening sunset or night half dark period), the design method of the lighting system (example The light emitting element may be configured size, and a light emitting element circuit array, electrical control system regulated manner, the second optical light mixing Light quality ratio design is carried out by factors such as design or packaging of ultraviolet light components, as well as planting situational requirements (such as plant growth morphology, production period, yield and quality, and suppression of pests and diseases). For example, when the application field is a simple greenhouse (for example, a plastic film or a glass greenhouse), the light source module 200 may be in infrared, red, blue, green, and ultraviolet light or may be 30%: 40%: 20%: 4%: 6% or 40%: 30%: 20%: 4%: 6% of the reference ratio light output intensity is matched (but not limited to this). The electronic control system 300 optionally stores a plurality of sets of predetermined light environment context patterns in advance based on the number and configuration of the light emitting elements. At this time, the user (for example, a farmer) can select a suitable light environment context mode according to the characteristics of the plant to which the plant is cultivated to provide a light quality and light quantity ratio required to be close to the theory, thereby obtaining the preset result.

An example will be described below. In the present example, the light source module 200 shown in Fig. 2 is employed. The light source module 200 may include 12 ultraviolet light emitting elements 201, 20 red light emitting elements 202, 4 green light emitting elements 203, 16 blue light emitting elements 204, and 48 infrared light emitting elements 205. The structure of the light source module 200 and the arrangement of the light-emitting elements 201-205 are fixed at the time of installation, wherein the maximum output ratio of each light-emitting element of the light source module is approximately 4.7% (ultraviolet light): 23.4% (blue light): 4.2% (green light): 40.8% (red light): 31.8% (infrared light). That is to say, under such a hardware device, the light intensity of the light source module 200 can be red, infrared, blue, ultraviolet, and green in order from large to small.

In the present example, the light source module 200 generates 18 sets of specific light output context modes via system control, and through these specific light output context modes, the light source turn-on time and different light environment conditions can be obtained for different plant species (including fruits). Growth morphology, yield and quality, functional components and planting light environmental context parameters for pest control. After that, the light output value of the illumination system can be adjusted to the desired planting light environment condition parameters, so as to further achieve the functional components that regulate the growth pattern of the whole plant, increase the yield, improve the quality, suppress the pests and diseases, and increase the health or taste. That is to say, the illumination system can adjust the number of light source modules according to a planting condition and a situational demand, and obtain a planting light environment parameter reflecting the above planting conditions and the above situation requirements through a planting process. As shown in Table 1: In Table 1, the light on time 1 indicates that the light-emitting element is turned on from 17:00 to 21:00 in the evening; the light-on period 2 indicates that the light-emitting element is from 22:00 every night to 02:00 on the next day; Each situation spectral intensity value 1 indicates that the light-emitting element is output at 100% light intensity, and each situation spectral intensity value 2 indicates that the light-emitting element is output at 50% light intensity, and each situation spectral intensity value 3 indicates that the light-emitting element is not turned on, that is, no light. Output.

This example is applied to strawberry as an example. The illumination system is used to regulate strawberry plant growth, fruit yield, fruit quality, functional components and pest control. The strawberry planting process is divided into two periods, from mid-January to mid-January. The boundary between the two periods. That is to say, the first period is from mid-October to mid-January, and the second period is after mid-January. FIG. 11B is a partial survey item result of different light environment conditions for the growth pattern of the first strawberry plant when the light source module of FIG. 1 is operated using the plurality of light environment context modes of Table 1; FIG. 11C is a plurality of using Table 1; FIG. In the light environment scenario mode, when the light source module of FIG. 2 is operated, the results of the partial investigation of the growth pattern of the first strawberry plant are determined by different light environment conditions; and FIG. 11D is the operation of the plurality of light environment context modes of Table 1. In the light source module, the results of some survey items on the growth pattern of the second strawberry plant under different light environmental conditions.

As can be seen from Fig. 11B, the leaf area of strawberry plants was the largest in the eighth group of light environment context mode. It can be seen from Fig. 11C that if the illumination is performed in the fourth group of light environment context mode, the maximum total fruit weight can be obtained in the first period, and the illumination is performed in the 15th group light environment context mode, and the maximum total can be obtained in the second period. The weight is heavy. Therefore, in order to increase the weight of the fruit, the fourth group of light environment situation patterns can be used in the first period. In the second period, the 15th group of light environment situation patterns was adopted.

In addition, as shown in FIG. 11C and FIG. 11D, in order to increase the total number of fruits, in the first period, the light source module 200 can be illuminated in the fourth group of light environment context modes, and in the second period, the fifth group of light environments can be changed. Situation mode to illuminate. In addition, in order to increase the anthocyanin content of the fruit, the first group of light environment situation mode can be used in the first period, and the seventh group light environment situation mode is adopted in the second period. In addition, the same cultivation environment can be used to control the growth pattern of the whole planting process. For example, taking the strawberry as an example, the eighth group of light environment context patterns can be used to promote the increase of the leaf area of the plant, promote the red turn of the fruit, and increase the hardness of the fruit. In addition, if the peduncle of the plant is to grow, the 10th group of light environmental situation patterns can be used for regulation.

In addition, through the example verification, it is found that during the growth process of strawberry plants, there are some important influencing factors affecting plant morphology and fruit in different periods. For example, some important influencing factors and items are shown in Table 2: Table 2: Strawberry plants in different periods Important influence factors of morphology and fruit projects

For example, according to the results of Table 2, the user (farmer) can select a suitable light environment context mode according to the desired result, for example, selecting the light quality/light quantity ratio of some specific light-emitting elements, and the light-emitting period, that is, according to The importance of important influence factors ranks the desired combination of planting light environment context parameters. Briefly, the electronic control system controls the amount of light emitted by the light-emitting elements of the light source module, and the method of adjusting the optical parameters of the light emitted by the light source module includes: setting a plurality of experimental light environment scenarios in a plurality of experimental groups Patterns to grow plants; measure multiple state parameters of plants in the experimental group (eg stem crown, stalk length, number of flowers, fruit firmness, fruit sugar, fruit weight, fruit length, fruit width, total fruit weight, total fruit) Number, powdery mildew, anthocyanins, etc.). Next, the importance of multiple impact factors affecting the state parameters in these experimental groups is analyzed, for example, by the Taguchi method or other analytical statistical methods. According to the importance of the impact factor obtained Decide on at least one light environment situation pattern to be performed.

Of course, the above-mentioned light environment situation mode selection and the specific conditions of each light environment situation mode are only for illustrative purposes, and are not intended to limit the scope of the disclosure. When the lighting system with these 18 sets of light environment situation modes is built for planting and cultivating other plants, the choice of the light environment situation mode can be adjusted according to the situation. In other embodiments, the light environment context mode is not limited to the above 18 types, and the opening and closing conditions of the light-emitting elements in the light source module may be changed according to the conditions of the actual planting environment and the growth of the plants. For example, the actual light environment context mode can be arbitrarily adjusted and established via the illumination system, which can be used to automatically or automatically sense parameters in the actual planting environment (eg, light in space or soil). After the quality, quantity, temperature, humidity, acid and alkali, or pests and diseases, plant growth status, etc., adjust the light output value of the illumination system to the optimal planting environment parameters to further control the growth pattern of strawberry plants and increase fruit yield. Improve the quality of the fruit, suppress pests and diseases, and increase the functional ingredients of health or taste. That is, the illumination system can adjust the optical parameters of the light emitted by the light source module according to the difference between the light environment condition and the selected planting environment environment parameter.

Further, in the present embodiment, the plant 50 is planted in a greenhouse 60, wherein the greenhouse 60 is, for example, a plastic film greenhouse or a glass greenhouse. Although the plastic film greenhouse can adopt a coated color film with different colors to regulate the light quality of sunlight irradiated on the plant 50, the drape film is easy to be contaminated with dust and material aging as the use time is long, thereby changing the plastic. The sunlight quality of the membrane greenhouse and the generation of light intensity attenuation problems. In addition, it is difficult for plastic film greenhouses to make different adjustments during the daytime sunshine environment, because It is necessary to replace the coated film with different light quality and replace it with a different color. It is not only time-consuming to replace the coated film, but also easy to increase the cost. In contrast, the manner in which the electronic control system 300 is used to adjust the light quality and the amount of light L emitted by the light source module 200 is easy to adjust, and can be adjusted differently depending on the plant, and can be adjusted. There is no need to use different drape films in a time consuming and costly manner.
