As the fourth generation of new lighting, LED light source has many characteristics different from other (Table 1), which makes energy-saving light source of choice. LED used in the field of plant cultivation also showed the following characteristics: rich wavelength type, coinciding with the synthesis and optical light plant morphogenesis consistent spectral range; the spectral width at half-wave width, pure monochromatic light can be obtained in accordance with the needs of complex spectral combinations; you can concentrate specific wavelengths of light irradiation balanced crop; not only can regulate flowering and seed crops, but also to control plant height and plant nutrients; less heat systems, small footprint, can be used for multi-dimensional combination of cultivation systems to achieve a low heat load miniaturization and production space; in addition, its exceptionally strong durability also reduces operating costs. Because of these remarkable features, LED is very suitable for a controlled environment plant cultivation facilities, such as plant tissue culture, horticulture and nursery and aerospace factory ecological life support systems.

LED used in plant research facility cultivation

Over the past decade, the rapid development of the area of ​​horticulture, plant growth light environment control lighting technology has attracted attention. Horticultural lighting technology is mainly used in two ways: one, in sunshine or less sunshine when time is short as supplemental lighting plant photosynthesis; two, as plant photoperiod, light morphogenesis induced lighting.

1, LED supplemental lighting as a research plant photosynthesis conventional artificial light generated too much heat, such as the use of LED lighting and supplemental hydroponic systems, air can be recycled, excessive heat and moisture may be removed, electrical energy can be efficiently into photosynthetically active radiation, and ultimately transformed into plant matter. Studies show that: LED lighting, the growth rate of lettuce, photosynthetic rates have increased more than 20%, the LED for the plant factory is feasible.

The study found that compared with fluorescent lamps, mixed wavelength LED light source can significantly promote the growth of spinach, carrots and lettuce, improve morphological indicators; enable beet bioaccumulation of the largest hair roots beet Accumulation of the most significant and produce hair roots the highest sugar and starch accumulation.

Compared with metal halide lamps, growth in line with pepper, basil plant wavelength LED under its stem, leaf anatomic significant changes occur, and with the optical density increased plant photosynthetic rate increase. Composite wavelength LED can cause the number of stomata marigold and sage are two plants increased.

2, LED as light cycle plant, induction lighting Photomorphogenesis

Specific wavelength LED can affect flowering time of plants, the quality and duration of flowering. Certain wavelengths of LED can raise the number of flower buds and flowering plants; certain wavelengths of LED can reduce the flowering response, regulation of the peduncle length and flowering will help cut production and market. This shows that the regulation can be regulated through the LED and the subsequent growth of flowering plants.

3. LED used in aerospace research Ecological Life Support System

Establishment of Controlled Ecological Life Support System (Controlled Ecological Life Support System, CELSS) is the fundamental way to solve the problem of long-term manned space life support, the cultivation of higher plants is an important element CELSS, which is one of the key light.

Based on the special requirements of the space environment, the light source used in the cultivation of higher plants space must have a high luminous efficiency, light output suitable for plant photosynthesis and morphogenesis, small size, light weight, long life, high safety and reliability record and no environmental pollution. Compared with cool white fluorescent lamps, high pressure sodium and metal halide lamps and other light sources, LED light more efficiently converted into photosynthetically active radiation; in addition, it has a long life, small size, light weight and features a solid state, and therefore In recent years, much attention in the cultivation of plants in the ground and in space. Studies have shown that LED lighting system can provide lighting spectral energy distribution, the energy conversion efficiency of light required for the plant more than 520 times the metal halide.

Prospect Analysis

LED with its inherent advantages are attracting the attention of the world. Especially in the global energy shortage concerns rise again in the background, the LED light source with high luminous efficiency, long life, safe, reliable, environmentally friendly and energy saving features, the LED lighting market prospects are more global attention.

In traditional agricultural production in general use ordinary electric light supplementary light and the application of different cover materials and other agricultural technical measures, such as using a monochrome fluorescent or colored plastic film, changing light environment to regulate cultivation environment plant growth and development. However, these measures there are different degrees of problems, such as lack of specific spectral components analysis led light quality treatment impure, the light intensity is inconsistent, or even close to or below the light compensation point of the plant, energy efficiency and low light irradiation. LED large number of applications results in the cultivation of plants in the environment show, LED can solve these problems, especially suitable for artificial light-controlled environment plant cultivation.

l LED Grow Light Principle

Plants need sun exposure to grow more lush. Light plant growth promoting effects on plant chlorophyll to absorb carbon dioxide and water nutrients, synthetic carbohydrates. But modern science can make plants grow better in the absence of the sun's place, people grasp the inherent principles of solar plants need to do is leaf photosynthesis, leaf photosynthesis required when external photon excitation to complete the whole process of photosynthesis, the sun's rays is the photon excitation energy for the process is over. Create artificial light also allows the plant to complete the process of photosynthesis, are a combination of fill light technology or entirely artificial light technology in a modern horticultural plants or plant. Scientists have discovered that the blue and red zone area is very close to the plant photosynthesis efficiency curve, is the best source for plant growth.

LED Grow Light Knowledge:

1, the different wavelengths of light for photosynthesis of plants affected are different, plant photosynthesis needs light, the wavelength of about 400-700nm. 400-500nm (blue) light and 610-720nm (red) for the greatest contribution to photosynthesis.

2, blue (470nm) and red (630nm) of the LED, just to provide light for plants, therefore, LED grow lights, the ideal option is to use a combination of the two colors. The visual effect, the combination of red and blue lights showing pink plants.

3, blue light promote leaf growth; red light helps to prolong flowering and fruiting and flowering.

4, the proportion of red and blue LED LED Grow Light is generally 4: 1--9: between a suitable, usually optional 4-7: 1.

5, when the plants fill light lamp to the plant, general distance blade height is about 0.5 m, 12-16 hours a day continuous exposure can completely replace the sun.

Using LED bulbs configure the most suitable semiconductor plant growth light

Set according to the proportion of colored lights to make strawberries, tomatoes become sweeter, more nutritious. With lights and holly seedlings that mimic plant photosynthesis outdoors. Photosynthesis is the means by chloroplasts of green plants, the use of solar energy, carbon dioxide and water into the storage of energy in organic matter and release oxygen in the process. Sunlight is composed by different colors of light, the different colors of light on plant growth can have different effects.

LED light source, also known as a semiconductor light source, such a light source wavelength is relatively narrow, the color of light can be controlled. It plants with irradiation alone, can improve plant varieties.

The test under the purple light holly seedlings, tallest, but the blade is very small, shallow roots also, like a malnourished. Seedlings under partial yellow light not only small, leaf looks lifeless. In red, light blue mixed growth holly grow best, not only strong, but also very well-developed root system. This LED light source is red, and blue lamp bulb in accordance with 9: 1 ratio configuration.

The results demonstrated that 9: red and blue one most favorable to plant growth, through this light source, strawberries and tomatoes plump fruit, sugar and vitamin C content increased significantly, but the phenomenon does not appear hollow. Irradiation for 12-16 hours a day for growth in this light strawberries, tomatoes, will be more delicious than ordinary greenhouse fruit.

LED Grow Light can also be used to plant winter supplemental light rain
