Entering the LED plants lighting industry should know six basic points

LED lighting can be widely used in the plant tissue culture, the production of leafy vegetables, greenhouse fill light, plant plants, plant breeding, cultivation of medicinal plants, edible plants, algae culture, plant protection, space fruits and vegetables, flowers planted, drive to kill mosquitoes and other field, planting out of fruits and vegetables, flowers, herbs and other plants to meet military border posts, alpine regions, lack of water and electricity resources required area, home office gardening, marine space personnel, and other regions or specific patient populations.

Currently on the market has developed and produced a number of LED plant lighting devices, such as LED grow lights, plant growth chambers, house plant grow lamp with LED, drive to kill mosquito lights. Wherein the LED Grow Light common morphology bulbs, lights, panel lights, lights, downlights, light grid and so on.

The following are entering the LED plants lighting industry should know six basic points.

First, LED plant lighting market demand so much, if you want to enter the greatest difficulty in what?

LED lighting plant is a product of biology, facility horticulture, vegetable, plant physiology, plant nutrition, bio-environmental engineering, LED lighting, intelligent control technology, interdisciplinary and organic development. So only good at semiconductor plants, one or both of the intelligent system are fully cross-collaboration is critical enough and research applications. The most difficult plants to enter the LED lighting market is to develop the production yield and quality of plant ecology LED light source or luminaire, we need to solve the intelligent control of light environment, plant photobiology, LED semiconductor technology issues and how to integrate the three integral development.

Second, the plant photobiology What does it mean?

Plant photobiology law is an important basis for LED lighting plant, including the number of properties under light conditions (light intensity and photoperiod), mass properties (light quality and spectral), electric light emission characteristics (duty cycle, frequency) and so on. Plant photobiology with high complexity and systemic. Light quality refers to the biological role of the type of light quality, including visible light, UV and far-red light. Light quality biology, we need to figure out the following issues: first, light quality biological function, a single light quality and research complex light quality on plant growth, yield and quality and impact of physiological metabolism, molecular biology and proteomics Mechanism ; second, between plant species and varieties of light quality and adaptability to exploit differences in the mechanism; third, light quality interactions with other environmental factors of biological mechanisms; fourth, the number of properties of light quality lighting facilities effective threshold and the reference value. In addition, a clear low-light stress biology light quality, light and response mechanism photosynthetic apparatus under continuous light operating efficiency also needed.

Third, why light recipe different companies the same plant will be different?

The establishment of various plant growth and development, quality and high yield the desired formulation development based LED lighting plant lighting industry. Light recipe is a high yield and quality as the goal, according to the characteristics of plant species and varieties of light quality growth parameter types and number of attributes required for each stage set. Each plant and different growth stages optimum lighting recipe is different. Why different companies for the same plant light formula will be different, even a big difference? The main goal of plant growth and business have a certain relationship. Simply put, companies according to market demand and their own development needs, can reduce the requirements and only need more than the growth of plants minimum light formula needs other environment on biological growth also relaxed the requirements of the case, not only the light recipes are not the same, for environmental control system will be very different. Instead, companies can also be critical, as far as possible to create the best environment for the growth of plants and conditions, such as research and development of light like a recipe. Future have been put forward with LED lighting plant China’s relevant standards and requirements, light recipe speak progressive unification or consistent basic conditions.

Fourth, LED plant growth light source and lighting research and development production requires attention to what principles?

LED Grow light lamps lighting plant is the core LED industry, companies need to develop formulations according to the light required for plant growth light lamps. Pay attention to the following four principles: First, high energy efficiency principles, formulate a reasonable degree of spectral components increase the maximum luminous efficiency LED light source, the light source and reduce the distance between the irradiated plants, reducing light loss and improve energy efficiency; second , low-cost principle, the cost is one of the most important factors that determine plant LED lighting industrial development; third, the principle of ecological security, in red and blue spectrum, a slight increase or a small amount of a green component to increase the visual health; the fourth priority the development of high value-added plant dedicated LED light lamps.

Fifth, what plants light control is the environment, including what?

Light environment control based on quality and high yield as the goal, the production plant factory system cultivated plant species and varieties grown each stage light formula is based on direct control of environmental parameters and switching of light through the computer’s time and space management. For example, greenhouse fill light to consider natural light diurnal variation of parameters, environmental parameters, plant photosynthetic parameters, plant growth stage and lighting properties, to implement cost-effective fill light approaches to meet the light intensity, light quality, photoperiod demand, energy efficient. Plant light environment control mainly refers to control LED lamps light quality, light intensity, photoperiod, spatial location and rate of movement and so on. Light environment control has obvious spatial and temporal characteristics, thus establishing a dynamic real-time control is very important to realize LED lighting light plant environmental control automation and intelligence is the trend.

Sixth, LED grow lighting design focuses on which indicators and performance?

LED plant lighting designers need to focus on the following indicators and performance: 1, illumination uniformity; 2, light quality group with rationality; 3, heat reliability; 4, LED power chip suitability; 5, light-emitting surface the efficiency; 6, visual comfort.

Four Largest Grow Light Market Analysis

According to market research firm Technavio latest research results show that, by 2020, the global market value will grow lights more than three billion US dollars in 2016 to 2020 will grow 12% CAGR.

Currently, the global market grow light is divided into four categories: fluorescent grow lights, LED grow lights, high pressure sodium (HPS) grow lights, grow lights incandescent and halogen lamps.

Global fluorescent grow lights market

By 2020, global growth fluorescent lamp market is expected to reach $ 1 billion, such products popular with home gardeners welcome. Standard fluorescent lamps commonly used in seed germination, but the efficiency is not high, in order to overcome the shortcomings of the standard fluorescent lamps, advanced technology will be manufactured with high yield and efficiency of fluorescent lamps. Compared with the standard fluorescent lamps, fluorescent lighting new R & D has a strong lower temperature, such products to be more efficient than incandescent bulbs and also cost-effective.

In addition, fluorescent lamp bracket will also lighter, easier to install, easier for users to use, but can also replace the lamp.

Global LED Grow Light Market

9x200wcreeledgrowligh4

By 2020, global LED grow light market will reach $ 1.9 billion, the annual compound growth rate of over 25%. LED Grow Light market is relatively new, technology has been in development, has introduced a more efficient product. LED life than ordinary energy-saving lamp 10 times longer, and far more than ordinary incandescent lamp. Although these lamps are more expensive, but more efficient, since no frequent replacement, but also save electricity costs. Compared with other lamps, LED less heat, and therefore eliminates the expensive and complicated cooling system cost. Use of other lamps need a cooling system because overheating will damage the plant tissues.

Because of the advantages of LED more, the world’s researchers are focusing on the development of LED grow light, and therefore the market will grow further.

Global HPS grow light market

By 2020, HPS grow light projected global market value will reach $ 157 million. Orange and red flowers make HPS issued production results and ripening, they give the greenhouse to provide adequate lighting. The benefits of high pressure sodium lamp is illuminated wide range, and high pressure sodium lamps should not be too close to the plant, because it generates a lot of heat. But in winter greenhouse does require more calories. After the high pressure sodium lamp with a long irradiation becomes weak, we need to replace. The average life of these lamps is 18,000 hours.

Agricultural equipment analyst Abhay Sinha said: “The high-pressure sodium lamps in all high-intensity discharge lamps, the most efficient, high-pressure sodium light efficiency six times higher than incandescent, very different, but also the future popularity of these lamps will help to promote indoor cultivation industry growth. ”

Global incandescent and halogen lamps grow light market

Global incandescent and halogen lamps grow light market value in 2020 of $ 79.5 million, a compound annual rate of decline of 1.5%.

Incandescent usually buy at the grocery store and hardware store, but incandescent lights do grow a disadvantage is not energy, no light part of the energy that will generate additional heat, Abhay said: “Although the beginning to buy incandescent the cost is very low, but the running costs to be more than fluorescent lamps, and therefore used as growth incandescent lamp is not suitable, a halogen lamp, too, because its performance is similar with incandescent lamps. “

Plant Growth Conditions

To understand how plants cultivated before, we must first know the conditions necessary for plant growth. Of course the sun, air, water is indispensable, but how much sun, how much to water, which requires your attention. Go outside understanding of plant growth environment.

Condition of plants is most needed is sunshine. In addition to the sun, but also with the air, temperature and humidity, moisture, etc. multiple conditions, in order to grow healthy. For those who want to learn horticultural novice, before the flower market, may wish to look into the outdoor plants. Strange, no one to take care of these plants, why also looked good? In fact, as long as the favorable environmental conditions, the plant is easy to grow healthy.

Look at what the whole plant under the sun? Which is in the shade? Wall plants only when the sun is in the sun to get it? We can further identify the same plant in different places of growth, plant growth conditions so you will need even more apparent.

Sunshine is the most important key for plant growth, according to the extent of saying therefore decided home environment suitable for what kind of flower. Plant has its own optimum growth temperature, general home common plant mostly tropical plants, special attention should be cold. Some drought-tolerant plants, some like plenty of moisture, must be adjusted depending on the plant habit. Plant growth medium is a medium, select the appropriate media make it easier for plants

Light intensity and time of various plants need are not the same, it is generally based on the needs of the plant will be divided into three kinds of light conditions, which is in the gardening books often see full sun, half shade and sunshine. Although the plant is best placed in the appropriate light conditions, but in fact, some plants that can be grown under different sunlight conditions, but may be fast or slow the growth of cattle production, flowering or not flowering, leaf color leaf unequal differences.

Full said means according to each of the above said direct sunshine time on the plant for about six hours, a whole day is simply to be the best from the sun. General outdoor no shade at the south-facing balcony or no, there is full sun conditions.

It needs full sun plants, also known as positive plants. Most flower plants, fruit trees, herbs and plants, aquatic plants, vines, succulents and so need full sun bad environment. If you need anti-season planting, you must fill-light use led grow light or other fixtures.

55

The so-called sunshine half refers to the sunshine filtered light – half intensity, not according to the time to comment. The location is under the shade outdoors, such as shade, north or east-facing balcony, south-facing windowsill or shading may shine more moderate sunlight.

Many indoor flowering plants such as pansy Africa, and most of the foliage plants are suitable for semi-sunshine environment. Part of flower plants can be kind, just bright colors may not be less amount spent.

Shade-tolerant, that is not saying direct sunlight, but it does not mean completely dull, but still there is enough light around the room near the windows, you can have a scattering of sunlight. You can also use artificial lighting to supplement the light.

Suitable plants: in principle, suitable for flowering plants. But Sun needs little foliage plants are grown in shade-tolerant environment.

Air: plants are also breathing when they are carrying out photosynthesis, you need air. Air is present in all the time, with outdoor air office has slaughtered, but the condition is not the same. Therefore, the air condition we can think of the degree of air circulation. The vast majority of plants need a well-ventilated environment. How to determine whether a well-ventilated, in fact, rely on their own feelings on the line, compared to the air-conditioned office, do you feel more comfortable outdoors. In a well-ventilated conditions, plants can grow more smoothly, and difficult to produce pest. However, too much wind will be harmful to plants, such as strong wind, high-rise next to the air conditioner or fan outlet, is not well-ventilated place.

Temperature and humidity: plants suitable for the growth of its temperature, as the temperature will be self-adaptation, in general, proper temperature is based on the growth of plants in different environments decisions, some like heat, some can withstand low temperatures. However, in summer and winter there are still too high, too low temperatures occur, will lead to heat exhaustion possible temperate plants, tropical plants can not stand the cold winter, then we should do because the plant needs to adjust the temperature on. In addition to wet the needs of different plants are not the same. Plants from tropical rain forests, like the more humid environment: a relative from the desert, on the environmental conditions necessary drying it. Therefore, in comparison arid or humid rainy season, but also pay attention to whether the plants adapt well.

Some Demands of Greenhouse Plants to LED Lighting

Artificial light is an essential part of commercial greenhouse production, such as indoor production, similar to the completely artificial light plant factory, no natural light indoors, to be totally artificial light. Lack of natural light, but also need artificial light, such as seasonal light deficiency (northern, southwest, north haze), in order to ensure the quality of horticultural products, artificial light increases and the like.

In practice, insiders pointed out that the designer during the design for LED grow light, there are some difficulties, such as lack of fill light LED lamp parameters, lack of design parameters; the higher the installation height, LED light can not reflect the advantages of brachytherapy ; while production of varieties, look for a large LED lighting technology risk; no economic calculation, can not assess the actual economic benefits; outside the laboratory without reference design case and so on. Finally, the designers still choose the traditional lamp, there are some considerations: detailed design parameters such as lighting, design method mature convenient; there are success stories reference, technical risk is small; a number of varieties can be used in the same light, will not cause cuts risk, economic benefit can be expected; extreme low temperatures, high pressure sodium lamp can add calories to make up for lack of heating.

For LED grow light, the industry needs and also some recommendations, one needs Universal / professional lighting, more fool-Korean goods, so relatively easy to promote, such as nursery lamp, light fruits and vegetables, leafy vegetables lights, flower lights, group Pui lights. If all greenhouse redesigned again, the cost is very high, if not standardized, it is difficult to standardize the user, it is difficult to standardize the production, the price will be very high. Universal / professional indoor lighting some needle, such as plant factory, some are against Daejeon, Fill it, there are some studies class.

On the other hand, to improve the design parameters. Because LED application, the designer will be from Standard and safety point of view, LED lamps and traditional lamps will be compared, so the LED lighting performance parameters as detailed as possible, to facilitate the direct selection of the designer. Reference lighting, styling lighting products should provide a complete design parameters for the designer to optimize the fill light scheme. Such as the XX curve, in order to achieve the fill light design visualization.

In addition, the applicability of new technologies, including the applicability and suitability of species to be regional pilot production, through pilot production to get the data can be used to guide production.

LED Grow Light: Energy Saving and Efficient

LED Grow Lights are mostly blue and red lights bead-based, providing the plant required energy according to plant light needs, promoting normal plant photosynthesis to help plants grow normally. The visual effect, the combination of red and blue LED plant growth lamp showing pink.

led grow light.jpg

Blue light helps plants in collaboration with, can effectively promote the growth of stems and leaves of plants, fruit formation, protein synthesis; red flowering plant can greatly contribute to help increase flowering rate and extend the flowering period, while increasing fruit set and fruit quality .

It was found that planting multi-word, LED grow lights effect is very significant, after using LED grow lights, plant growth rate than the average natural growth of plants up to about three times faster, but also solve the annoying lack of sunlight in winter greenhouses and plant Lights enhance collaboration light plant chlorophyll, carotene and anthocyanins used as needed to shorten the cycle of plant growth and maturation time to market, increase production while also improving the quality of the product.

LED light source known as a semiconductor light source, narrow wavelength control, can send a specified wavelength spectrum, usually seen in the color of light is controlled to control the wavelength of light (spectra).

LED grow light power is small, but the efficiency is very high indeed. Most of the time we use lamps, light emitted from a variety of bands, covering the entire range of visible light, only red and blue for normal growth of the plant, a large part of the energy is wasted, which is why a few ten-watt LED grow light also benefits less than the effect of planting hundreds of watts of traditional plant lamp.

Traditional plant species lamps, sodium comparative lack of Blu-ray, the relative lack of red mercury. After multiple test summary. Overall performance LED grow light to be higher than many other plants grow light in agriculture efficient, energy-saving made truly outstanding contributions.

 

Why LED Grow Light is an High-tech LED Application ?

Indicators LED Grow Light LED industry can be said to be the most copied. A variety of plants in the unique geographical environment to survive, including sunlight, temperature, altitude and soil, etc., they form a unique breeding flowering response strategy in the last million years of evolution in the life of the natural environment, and that is the flowering season is limited to a suitable period to ensure that the offspring can smoothly growth and development, which is the phenomenon of light cycle of a plant. Most plants in natural selection and evolution have gradually adapted to the natural rhythm of light environment, to form a clear reproduction of the best seasonal. Studies have shown that photoperiodic induction of flowering plants important environmental factors, analyzed the performance of the plant breeding laws in order to improve output efficiency of agricultural facilities, and promote healthy development of the farming industry.

led grow light

Photoperiod is an important factor inducing flowering plants. Based on the flowering photoperiod physiological pathway analysis, an overview of the photoperiod specific application in plant flowering, it pointed out the application to consider other effects of environmental factors for agricultural facilities flower planting and efficient development of a useful ideas, but also for LED grow light manufacturers and control designed to provide a scientific basis.

Flowering photoperiod physiological pathways

Leaf feel photoperiod signal, this flowering stimulant conducted to the tip of the stem growing point. Phytochrome and Cryptochromes as a light receptor is involved in this pathway, through gene expression, and the completion of flowering control the formation of floral organs. At least three types of photoreceptors in higher plants: Feel the red and far-red phytochrome, absorbs ultraviolet (UV-A) and Blu-ray Cryptochrome and phototaxis factors.

Plant photoperiodic response types

Plant Nutrition and transferred from a purely vegetative growth to reproductive growth is double the plant life in a major turning point, and its importance for the continuation of the plant species itself. United States Gardner (W.W.Garner) and Arad (H.A.Allard) proposed a “plant itself can measure the day length and season accordingly perceived” concept in 1920, which is now called photoperiodism.

Within a certain period of development, based on length of day type of reaction can be divided into the plant long-day plant (long-dayplant, abbreviated as LDP), short-day plants (short-dayplant, abbreviated as SDP), Day-neutral plants ( day-neutralplant, abbreviated as DNP). LDP refers to the exposure time must be longer than a certain number of hours per day and after a certain number of days to flowering plants. Such as wheat, barley, canola, henbane, osmanthus and sugar beet, and the longer the exposure time, the earlier flowering. SDP refers to the illumination time of day must be shorter than a certain number of plants when to flower. As appropriate to shorten the light, flowering earlier, but the extension of the light, the delay flowering or not flowering. Such as rice, cotton, soybeans, tobacco, begonia, chrysanthemum, morning glory and cocklebur like. DNP refers to any day conditions can flowering plants, such as tomatoes, cucumbers, roses and Clivia and so on.

Flowering light cycle regulatory application of key issues

1 plant critical day length

Plants critical day length refers to the circadian cycle, inducing short-day flowering plants can endure the longest sunshine or inducing long-day flowering plants must shortest sunshine. For the LDP, the Japanese grew up in the critical day long, even 24 hours can blossom. But for SDP, the date must be smaller than the critical day length to flower, but not too short flowering.

2 key manual control flowering and photoperiod

SDP flowering decide on the length of the dark period does not depend on the length of time illumination. LDP flowering sunshine required length longer than the SDP is not necessarily required day length flowering.

We learned flowering photoperiodic response and key type, you can extend or shorten the length of day in a greenhouse, control flowering, flowering time to solve the problem. Artificial light can accelerate the extension of long-day plants flowering, appropriate to shorten the light, can promote short-day plants flowering early. It intends to delay flowering or non-flowering, setting operation can be reversed. If the long-day plant cultivation in the tropics, due to lack of light, they will not bloom, the same short-day plants cultivated in temperate and boreal also because exposure time is too long to blossom.

3 introduction, breeding

Artificial plants photoperiodic control of this has very important implications for the introduction, breeding plants. SDP is introduced to northern South seed to bloom early, late-maturing varieties need. Similarly south species northward, to be early-maturing varieties; seed for LDP is introduced north south, to delay flowering, to be early-maturing varieties. Similarly south species northward, to be late-maturing varieties. For example, the genus Malvaceae Hibiscus Roselle is SDP, if south species northward extension of the vegetative growth stage. Budding, flowering, seed of lag, early frost was easily hurt, then you should know that need shade treatment.

4 red and far-red floral induction

The main receiving Photofrin red (Pr) and far-red (Pfr) signal, the impact of flowering induction. Flower effect is not determined by the absolute amount of Pr and Pfr, but affected Pfr / Pr ratio. SDP in the lower Pfr / Pr ratio under the flower, while LDP flowering stimulate the formation of substances requires a relatively high Pfr / Pr ratio. If the dark period is interrupted red light, the ratio Pfr / Pr increases, so SDP flowering is inhibited. LDP to Pfr / Pr ratio stringent requirements better than SDP, but long enough illumination time, relatively high irradiance and far-red light to induce flowering LDP is essential.

LED lighting effects and control system

Photoperiodic control of light and dark is a state within a day range, can be artificially set automatically change. LED control technology has been controlled by a single initial constant current, the current development of SCR dimming, PWM dimming, DMX512, DALI, ZigBee protocols such as dimming. Control mode is also developed from the first wire technology to IR, FR, Wi-Fi short-range wireless control. The controller uses an embedded structure, the optical parameters can be real-time monitoring data via the Internet to communicate with a remote server, the system can easily achieve the brightness regulation time.

Summary

In fact, even for one door outline families have different segments. Their needs are not the same light. Light cycle regulation environmentally safe, low cost LED lamps and labor-saving features and simple in agricultural facilities. Therefore, rational and effective use of light can break the cycle of seasonal restrictions factory cultivated plants within certain limits, to achieve anti-season to stimulate or inhibit, in order to achieve the purpose of efficient production of agricultural products. With the continuous development of science and technology, the photoperiod phenomenon is bound to a more profound understanding. The photoperiodic regulation of flowering plant breeding applied to industrialized species colonization industry, will promote the steady and rapid development of agricultural facilities and LED lighting applications Plant Industry.
