      (Summary description)In the field of plant lighting, as one of the fastest growing agricultural lighting fields in recent years, LED has obvious advantages in plant lighting because of its high luminous efficiency, low heat generation, small size and long life. Plant lighting and other LED lighting With the maturity of technology, companies have moved from the general lighting market to the field of plant lighting, and plant lighting has broad prospects. So, what problems exist in LED plant lighting in the process of development? What is the current proportion of LEDs in plant lighting? What is the future trend of LED plant lighting compared with other light sources in plant lighting? At the plant lighting conference held a few days ago, the guests discussed this in detail. 1. How to treat the current development of the entire plant lighting industry? Fang Wei: The future of the plant lighting industry should be very optimistic. From the current sales volume of plant products, whether it is the leaf of the entry or the ingredients of health, it will even become the medicine of the future trend, whether it is domestic or Taiwan. The prices of these products are getting higher and higher, and the future of plant lighting must have a bright future. The premise is that your product must be distinctive. The product has its own characteristics. The next step in determining whether the industry is successful is to see who can successfully execute the commercial marketing model. The life cycle of plant products is very short, but many people will not sell them, and the products will not be sold. In fact, products need different routes. From fresh vegetables to processed products, from semi-finished products to finished products, when products become diversified, the channels of sales become diversified. Sales naturally go up. 2. At present, LED accounts for the total market share of plant lighting fixtures? Lun Lun: At present, the plant lighting fixtures used in greenhouses are mainly high-pressure sodium lamps. The domestic ones are mainly fluorescent lamps. LED lamps are practically few. In recent years, the growth rate of applications in the cannabis field has accelerated. Some plant factories also have LEDs are used, but LEDs currently account for a small percentage. 3. What are the advantages of vegetables grown with plant lighting compared to ordinary vegetables? Jiang Jingjing: There are several characteristics. The first biggest feature is that the vegetables grown in the plant factory are very safe. Only in a controlled environment, it is illuminated with LED lights, and its environment and nutrient solution are controlled by hand. This is Beyond green vegetables, and do not need to use any pesticides or herbicides in the plant, our nutrient solution avoids heavy metal pollution in traditional soil. The second feature, because we are artificially created shortcuts, the air is filtered, the water is purified, and the dust and bacteria are very low. The third characteristic is that the products of the plant factory are very fresh. Compared with the losses caused by long-distance transportation of other traditional agricultural plants, the plant factory is placed around the big city. It can be completed within 12 hours from the receipt of the table, and the effect of planting vegetables at the door of the house. it's the same. In addition, compared with traditional agriculture, plant lighting factories can be customized. Traditional agriculture is limited by the fact that climate and temperature change all year round. Although greenhouse greenhouses can now eat anti-season products, plant factories have no concept of season. The products are the same throughout the year and are highly efficient. Fang Wei: We should have this kind of thinking: the value of the vegetable factory and the ordinary vegetables are different. In Taiwan, the vegetable factory's dishes only need to be verified by rigorous scientific standard data. Indoors, the detection of air dust is a technical standard of one cubic centimeter of dust content of 100,000. If this standard is met, it is identified as clean. The clean room standard is 10,000 dust per cubic centimeter, while the general food processing plant is 100,000. The plant factory is not a clean room, so it is enough for the plant to meet the environmental requirements of the food processing plant. The dishes that have come out have reached the standard of raw food. 4. Are there any studies on the plants grown in plant factories that have defects in function or performance? Will artificial planting change the structure of the dish, or other similar genetically modified problems? Fang Wei: Artificial light is basically the same as sunlight, and there is no difference in the growth of plants. The only difference is that if the plant is reddish, you will use the exact spectrum, it will produce lettuce with normal coloration of red leaves, but you said that the lack o

      Information

      In the field of plant lighting, as one of the fastest growing agricultural lighting fields in recent years, LED has obvious advantages in plant lighting because of its high luminous efficiency, low heat generation, small size and long life. Plant lighting and other LED lighting With the maturity of technology, companies have moved from the general lighting market to the field of plant lighting, and plant lighting has broad prospects.

       

      So, what problems exist in LED plant lighting in the process of development? What is the current proportion of LEDs in plant lighting? What is the future trend of LED plant lighting compared with other light sources in plant lighting? At the plant lighting conference held a few days ago, the guests discussed this in detail.

       

      1. How to treat the current development of the entire plant lighting industry?

       

      Fang Wei: The future of the plant lighting industry should be very optimistic. From the current sales volume of plant products, whether it is the leaf of the entry or the ingredients of health, it will even become the medicine of the future trend, whether it is domestic or Taiwan. The prices of these products are getting higher and higher, and the future of plant lighting must have a bright future. The premise is that your product must be distinctive.

       

      The product has its own characteristics. The next step in determining whether the industry is successful is to see who can successfully execute the commercial marketing model. The life cycle of plant products is very short, but many people will not sell them, and the products will not be sold. In fact, products need different routes. From fresh vegetables to processed products, from semi-finished products to finished products, when products become diversified, the channels of sales become diversified. Sales naturally go up.

       

      2. At present, LED accounts for the total market share of plant lighting fixtures?

       

      Lun Lun: At present, the plant lighting fixtures used in greenhouses are mainly high-pressure sodium lamps. The domestic ones are mainly fluorescent lamps. LED lamps are practically few. In recent years, the growth rate of applications in the cannabis field has accelerated. Some plant factories also have LEDs are used, but LEDs currently account for a small percentage.

       

      3. What are the advantages of vegetables grown with plant lighting compared to ordinary vegetables?

       

      Jiang Jingjing: There are several characteristics. The first biggest feature is that the vegetables grown in the plant factory are very safe. Only in a controlled environment, it is illuminated with LED lights, and its environment and nutrient solution are controlled by hand. This is Beyond green vegetables, and do not need to use any pesticides or herbicides in the plant, our nutrient solution avoids heavy metal pollution in traditional soil. The second feature, because we are artificially created shortcuts, the air is filtered, the water is purified, and the dust and bacteria are very low.

Compared with the losses caused by long-distance transportation of other traditional agricultural plants, the plant factory is placed around the big city. It can be completed within 12 hours from the receipt of the table, and the effect of planting vegetables at the door of the house. it's the same.

       

      In addition, compared with traditional agriculture, plant lighting factories can be customized. Traditional agriculture is limited by the fact that climate and temperature change all year round. Although greenhouse greenhouses can now eat anti-season products, plant factories have no concept of season. The products are the same throughout the year and are highly efficient.

       

      Fang Wei: We should have this kind of thinking: the value of the vegetable factory and the ordinary vegetables are different. In Taiwan, the vegetable factory's dishes only need to be verified by rigorous scientific standard data. Indoors, the detection of air dust is a technical standard of one cubic centimeter of dust content of 100,000. If this standard is met, it is identified as clean.

The plant factory is not a clean room, so it is enough for the plant to meet the environmental requirements of the food processing plant.

      4. Are there any studies on the plants grown in plant factories that have defects in function or performance? Will artificial planting change the structure of the dish, or other similar genetically modified problems?

       

      Fang Wei: Artificial light is basically the same as sunlight, and there is no difference in the growth of plants. The only difference is that if the plant is reddish, you will use the exact spectrum, it will produce lettuce with normal coloration of red leaves, but you said that the lack of anthocyanins in vegetables will be different, but less nutrients. The dishes that may be planted by the water culture system will have a tender taste. Some people like it very much. Some people say that it is unnatural. People are the only animals that wear clothes, but we don’t feel unnatural when we wear clothes, so don’t take the word nature. Unlimited magnification.

       

      Plant factories use data to speak. We adjust the light to produce a beneficial component. The ratio of blue light to red light in the sun is fixed, but the lighting can make more of the ingredients we need, but it does not change the vegetables. Genes, this is the ability of the plant itself, we have not changed the genes of plants.

       

      Nutritional ingredients are the end use of vegetables. Some nutritional values ??are higher. Some nutrients are not what we need. When we need a certain component of plants, we can regulate them through physical conditions. This is the benefit of plant factories. The growth of beneficial components of the human body, or by changing the growth environment of the vegetables to adjust different tastes.

       

      5. How do you think that growing marijuana is illegal in China, but it is legal in the Netherlands? What is the development of cannabis cultivation?

       

      Chen Guangcai: Cannabis itself is a double-edged sword, and its drug value is unquestionable. There are different laws in different states of the United States, depending on how the local government views it. At present, if you want to grow marijuana in China, you must have some special permits or plant in some special places.

       

      Liu Yang: Many states in the United States have legalized the cannabis market, and mature lamps are now in use. Moreover, they are now looking for a more efficient LED luminaire solution than the high-pressure sodium lamp. If your LED luminaire solution has no obvious advantage over the high-pressure sodium lamp currently used, there will be some obstacles in promotion.

       

      6. What are the advantages and disadvantages of LED and traditional light source metal halide lamps (HID) in plant lighting? What is the development trend of ceramic lamps in the domestic and international plant lighting market?

       

      Thunder: High-pressure sodium lamps have been used for a long time in agricultural production. LEDs have just begun to be used. However, as general lighting, LED market share is getting higher and higher. Many traditional lamps have been replaced by LEDs. This is the inevitable development of science and technology. trend. However, the spectral output of metal halide lamps is relatively fixed, it is difficult to control the change of spectrum, so it is suitable for the growth of certain plants. At present, metal halide lamps are widely used in tomato planting, but if it is a plant factory, LED is better than it. Much more, its spectrum is more suitable. However, the current LED QE value is compared with metal halide lamps, LED has no obvious advantage.

       

      Fang Wei: HID is more difficult to apply to vertical farms, one is its heat, the other is its volume. In the greenhouse, HID is also difficult to compete with high-pressure sodium lamps, because the spectrum tends to be different. The world's greenhouse artificial light is basically high-pressure sodium lamps. The early application of LEDs in the greenhouse is Dutch, and wants to replace high-pressure sodium lamps. But later found that it is not feasible, the high-pressure sodium lamp is very high in the greenhouse, about 4, 5 meters in height, a lamp covers a large area of ??the plant below, the LED installed in this high light will be much less, so the Netherlands currently uses the combination of the two The way, the headlights use high-pressure sodium lamps, plants and plants are 15 to 20 cm apart, and the height-adjustable LEDs are used. The blades above the results are specially used. The combination of the two is very good, and the LEDs are basically enough as long as the red light is enough. .

       

      7. What is the difference between hydroponic vegetables and plant factories? Will there be insect growth in vegetable plants?

       

      Jiang Jingjing: Whether it is a greenhouse or an indoor artificial light factory, it will grow insects. The key is how to control, the greenhouse greenhouse is a semi-manual control environment, if the state of the switch door is not well managed, there will be insects coming in, usually there is a lot of space and insects come in. Plant factory management and greenhouse greenhouse management are not a strict condition. We enter the plant factory and protect human hair. In addition, the air and water of the plant factory are purified or filtered. If strictly in accordance with the management model of the plant factory, The probability of long worms is very low, so pesticide plants are not allowed in plant factories. In greenhouses, we can only try to reduce the proportion of pollution, hydroponic cultivation through nutrient solution is one of the methods.

       

      On the basis of different light quality, how to ensure its luminous flux density? Also, how to make sure it is in the same light intensity. For example, red and blue light sources are combined into the same power, and the blue chip is not the same as the red chip voltage chip. Different numbers seem to represent different light intensities, that is, PPF is different because of the luminous flux and plant chlorophyll. A and B have a relationship.

       

      Chen Guangcai: Even with the same PPF, the concept of light effect per watt, the effect of different spectra on plant growth is certainly different. Now many of the lamps sold in the market are measured by PPF per watt. I think this is not comprehensive because he does not contain the spectrum. Effective PPF is very important for plant growth spectroscopy.

       

      We all know that in the design of the luminaire, it is very difficult to achieve complete uniformity of the spot light of any one lamp. It can only be realized by optical design at the stage of luminaire production, and the light is made more uniform as much as possible. Some linear lamps of power are doing very well. If you want to fill the light in the greenhouse, you need a more precise optical design.

       

      8. When conducting plant lighting studies, does the light test performed under the same PPFD and the different PPFDs result in different final test results?

       

      Fang Wei: The same situation as PPFD compares the spectrum. If the PPFD is high or low, the spectrum is different, and the research results are basically not convincing. However, this depends on the direction of the research. If it is PPFD, the spectrum is different. This is the study of the spectrum. Some studies are different for PPFD, but the energy consumption is the same. The same lamps are used normally, such as each 20-watt lamp. Five lights are lit, and the adjustment of the height is compared to the difference in cultivation strength, which should be considered together.

       

      I think there are several indicators that can be used to measure the overall efficiency of a plant. The first is to measure the amount of light after the lamp is installed. The indicator of the amount of PPFD divided by the watt is the indicator of the light source itself. How many photons are generated by the light source, and the PPFD of the cultivation surface needs to be measured, and the PPFD unit is used as an indicator to measure the condition after the loading.

       

      There is also an indicator called power production capacity, from the sowing of vegetables to the production of finished products, counting the total vegetable cultivation, divided by the electricity consumption, this indicator can measure the energy production capacity, that is, how many vegetables are planted per degree of electricity.

       

      The last indicator is the photon's productivity. By looking at the plant growth performance through the same number of photons in different spectra, the pros and cons can be judged immediately.
