With the increasingly fierce competition in the general lighting market, many LED manufacturers have launched market segments such as plant lighting, ultraviolet LED, and visible light communication to open up a new way.
At present, some domestic lighting companies are accelerating the layout of plant lighting, and the application of LED in plant lighting has gradually begun. In fact, many overseas LED companies have begun to deploy the plant lighting market, and the competitive landscape has quietly proceeded.
Philips Lighting
Philips has been in the field of plant lighting for 50 years and has worked extensively with growers around the world to have a rich experience in the effects of different light formulations, different lighting conditions and different production methods on plant production.
At the same time, Philips has a strong team of plant specialists, and also cooperates with renowned research institutions such as Wageningen University in the Netherlands, and has received technical support for many light formulas. This data has been continuously accumulated and collected.
Currently, the company has implemented its LED plant lighting program in several countries in Europe and Asia, and its parent company location - the Netherlands is the leading country in modern horticultural agriculture technology, so it has a good industrial, technical and cultural background.
Osram
In recent years, OSRAM has gradually focused its LEDs on the application level of plant lights to fully attack the agricultural market.
Based on the wavelengths required for plant lighting, OSRAM has introduced LED products with deep blue 450nm, red 660nm and far red 730nm. 730nm far red LED is a new product developed by Osram for plant lighting, which can control plants from germinating to The vegetative growth goes to the whole process of flowering.
At present, OSRAM has a relatively complete patent layout in the global LED market. If the downstream manufacturers of the joint holding company or the research institutes enter the plant lighting field, they will have strong competitiveness.
GE Lighting
GE is one of the major suppliers of plant growth light sources in the Chinese market. Its high-pressure sodium lamps are widely used in China's vegetable greenhouses as artificial light sources. The LED plant luminaires are designed to evenly disperse highly directional LED light and illuminate different wavelengths of light depending on the growth stage of the plant.
For example, in the early stages after exiting the nursery, light white light mixed with white and red LED light sources is illuminated to promote photosynthesis. The reddish light from the LED illumination with the red-blue LED source is then illuminated to promote the growth of the leaves and rhizomes. Near the harvest, white light is again illuminated to promote photosynthesis.
With this method, not only is the power consumption reduced by 40%, but the same area is increased by 50% compared to when only fluorescent lamps are used.
Mitsubishi Chemical
Mitsubishi Chemical began selling plant factory systems using LED lighting in 2012. The first product has been sold to the plant of MirUpakovki, a plastics forming and processing company in St. Petersburg, Russia. The system will be installed on the underground floor of the plant, all using LEDs as a source of photosynthesis for the cultivation of lettuce and young leafy vegetables.
In 2014, Mitsubishi Chemical Holdings Group of Japan joined hands with China National Supply and Marketing Cooperatives to launch sales of pesticide-free vegetable automatic cultivation systems throughout China. It is planned to build plant factories in 50 locations in 15 Chinese provinces such as Jiangsu by 2017.
Toshiba
In 2014, Toshiba established a “Cleanhouse Vegetable Garden†in the idle floppy disk factory in Yokosuka, Kanagawa Prefecture, and planted thousands of vegetables such as lettuce, spinach and sugar beet on the production line used to assemble floppy disks.
In addition, Toshiba Corporation of Japan is also preparing to build a new plant factory overseas, and has begun to consider building large plant factories in Asian countries such as China.
Fujitsu
In 2013, Fujitsu transformed its Aizuwakamatsu semiconductor plant in Fukushima Prefecture into a lettuce cultivation plant, using the sensor monitoring technology to grow lettuce in a sterile clean room.
At present, Fujitsu's dust-free lettuce has a daily production capacity of 3,500 trees, with an annual output of 1.3 million. According to projections, the price of such lettuce is very high, 500 yen per 90 grams (about 30.5 yuan), and the price of super pork is ten times. Fujitsu's annual profit target for lettuce is around 150 million yen (about 8 million yuan), and in 2016 it will reach 400 million yen (about 20 million yuan).
In recent years, Fujitsu has applied manufacturing technology to plant factories to significantly reduce agricultural production costs. The use of energy-saving technologies has also become a driving force for SMEs to enter plant factories, and plans to promote them to emerging countries to help their agricultural development.
Sharp
Since 2009, Sharp has started research on strawberry cultivation with Osaka Prefecture University and started an empirical test in Dubai in 2013.
In addition, Sharp has also built a plant factory building for the cultivation of strawberries in Dubai and has begun experiments. Sharp intends to conduct a variety of empirical experiments to achieve operational goals. Compared with Japan, Dubai's solar thermal resources and labor costs are lower, and plant factory operating costs are lower.
Sharp's strawberry cultivation uses LED and other original technologies, and hopes to accelerate the pace of restructuring through the launch of new business. Sharp will place experimental equipment in Dubai, which will be introduced to trading companies and local supermarkets, restaurants, etc., and may expand beyond the UAE in the future.
Matsushita
Matsushita began researching the artificial light plant system in 2012. In August 2013, the company built a pilot plant at the company's Fukushima plant and began selling the system in April 2014.
In 2016, Panasonic delivered the "Artificial Light Plant Factory System" to SG Green House, a subsidiary of the Western Gas Company of Japan. SG Green house began to carry out cultivation demonstration experiments in January 2016, and will start selling "low-potassium lettuce" that will reduce the potassium content to less than 20% (98 mg/100 g or less) from May 20.
According to Matsushita, the plant factory system will provide a homogeneous cultivation environment while reducing power consumption, improve the rate of cultivation and contribute to the industrialization of agriculture. SG Green house sets the system in a new cultivation building, which can produce 3,500 low-potassium lettuce per day.
to sum up:
At present, the sales market of LED plant lights is mainly concentrated in Japan, South Korea, Central America, Europe and other countries and regions with less agricultural personnel. In the future, with the improvement of LED plant growth lamp technology, its application market will enter an outbreak period.
It can be said that whether it is from the perspective of promoting the development of modern agriculture or the realization of energy conservation and environmental protection, LED plant lamps are of great significance in agriculture, and the status and development needs of agriculture also provide new developments for LED plant lights. opportunity.
