Dongguan LED enterprises to enter the field of bio lighting

Plant factory has become a hot topic recently, but also to promote the production of a variety of LED lighting products eye-catching. With the emergence of the first generation of LED lighting overcapacity crisis, more and more enterprises in Dongguan LED began to turn to the fourth generation of new lighting, the use of LED light source to create an indoor environment, such as sunshine growth environment.

10 years experience in optoelectronics industry deep Wright, moved from Shenzhen to Dongguan, in a small part of LED biological field lighting; Dongguan Chun Biao photoelectric science and technology in Taiwan to introduce technology to launch LED growth light module; Dongguan Kai Xin agricultural science and technology limited company in the future with the intention of vegetable production enterprises output LED bio lighting technology and equipment transformation. However, there are companies that, due to the high cost of lighting LED biological field, there is no mass production. However, with the development of technology, the cost of the entire LED industry are lower trend, I believe the future is like LED plant growth lamp market prospects are broad.

Do not waste the spectrum and save electricity with light source to control plant growth speed

As we all know, the growth of plants need sunlight, only the sun can help the plant to complete photosynthesis, can really use light to replace the growth and development of the sun? Shi Guangdian, deputy general manager of deep light, said, LED light can simulate the specific spectral components of sunlight, which has been widely recognized in the field of botany research results. It is understood that in the plant kingdom, is dominated by green plants, in all photosynthetic oxygen in the body of the biological clock, leaf chlorophyll two absorption peak of the sun, are near near 440 nm and 680 nm blue red zone, a region located in the blue, a in the violet region, and in the few 500-600 nm green light absorption, so we see that plants are basically green.

"In fact, most plants need only red and blue, and most of the rest of the light is reflected back. "Shi Guangdian said, LED plant growth lamp can emit red light and blue light specific to the plants, so the efficiency is very high.

Shi Guangdian introduction, LED is different from the incandescent light, single chip light-emitting, can provide a specific growth stage of the plant specific spectrum. The wavelength of 440-490 nm is blue, can promote the growth of green leaves; the wavelength of 600-700 nm red, helps to blossom and prolong florescence; violet and ultraviolet ray in wavelength 300-440 nm, is to promote energy plants to produce pigment, and directly affect the formation of plant phosphorus and aluminum elements and absorption of vitamin D, cuticle the accumulation of dry matter, and.

In fact, before the LED plant lighting, modern gardening and plant the plant has had a "light" technology, application of fluorescent lamp, high-pressure sodium lamp etc.. However, these light sources contain a large proportion of infrared and green light components, and the light source is not adjustable, both a waste of electricity, but also a waste of light energy.

With the maturity of LED lighting technology, LED light source and wavelength tunable technology gradually into the field of lighting. In general, LED power plant growth lamp of ten watts or less, equivalent to tens of watts or even hundreds of watts of power of traditional light effect. In addition to LED than traditional lamps to save electricity more than 90%, the biological field of lighting operation costs greatly reduced.

Not only that, LED can also realize the control of the growth rate of plants, flowering plants can be extended, so that economic crops can not be limited by the season, accelerate the results. For example, the plant can carry out photosynthesis for 16 hours a day, but the natural light is very limited, making the plant grow slowly. If you use the LED lamp, sustainable to plants with light, instead of natural light with LED light, vegetable maturity can shorten the 1/3 fastest, can realize the production, can be harvested 15 days had grown vegetables as long as 5 days, which is to promote the typical examples of plants irradiated with LED light.

The concept of plant factory, is to become a vegetable greenhouse plant workshop, each workshop has a different LED light, soilless cultivation of plants can be based on the needs of different growth stages, moved to different workshops to promote health. "Shi Guangdian, currently in Zhuhai's lab has already started training, LED can make plants grow fast," "can also slow down.

Urbanization and promote the further development of the industry

From the global market, LED plant light sales market is mainly concentrated in Japan, South Korea, the United States, Europe and other countries and regions engaged in agricultural personnel less.

According to a global industry survey, global LED growth light output from 2013 onwards, began to show rapid growth in the scale of tens of millions of dollars, but is expected in 2014 will exceed $35 million, is expected to reach $300 million in 2017. A number of large international companies have increased their input to the LED plant plant innovation.

With the promotion of LED plant growth lamp permeability, the Chinese market is slowly rising. Through the search engine, we will find that many of the Dongguan LED companies have launched a monochromatic light to promote plant growth LED. An analysis of the industry, the traditional LED lighting market competition has intensified, for biological lighting is a new field, but as long as through the better application of spectrum law.

Now the cost is still high, an ordinary LED for the growth of leafy vegetables in general 400 to $500 a lamp, when the future can usher in the outbreak is not to say. "Shi Guangdian said, plant growth cycle and wavelength are not the same, the process of difference, the price is very different. At present, the energy production is only the LED lighting of leafy vegetables.
