Plant lighting is on the rise, what is the prospect of the plant factory?
According to statistics, the world population has risen from 2.5 billion in 1950 to 7.4 billion in 2016, growing about three times. It is estimated that by 2050, the 10 billion mark will be broken. There is no suspense, the population explosion will inevitably lead to resource constraints. In traditional agriculture, high-productivity and energy-saving solutions have been sought for the increasing demand for stress. Therefore, it is expected that plant factories and agricultural lighting will play an important role in addressing climate instability and the balance between supply and demand. Some experts have analyzed that the market prospects for LED application in plant lighting are quite optimistic, and the market size is expected to grow rapidly. In 2017, the plant lighting (system) market was about 690 million US dollars, including 193 million LED lamps. It is estimated that by 2020, the plant lighting (system) market will grow to 1.424 billion US dollars, and LED lamps will grow to 356 million US dollars. At the same time, we can see that the major lighting manufacturers in the US market have stepped up the layout of plant lighting and engineering lighting, and it is expected that there will be a significant increase in revenue in 2017, so the proportion will also increase to 35%; including the Chinese market In the past two years, it has gradually become a regional market for domestic and foreign manufacturers. For example, Mitsubishi Chemical of Japan will build 50 plant factories in China in 2017, and the domestic Zhongke Sanan will also invest heavily in the construction of plant factories, which will further drive Market demand. The proportion of the Chinese market rose from 12% in 2016 to 15% in 2017. Undoubtedly, LED plant lighting as an important part of the plant factory has attracted a lot of LED lighting related companies around the world, and they are planning to plant the field of plant lighting. In this article, Xiaobian will introduce the recent new actions and achievements of several LED international giants in plant lighting. It will also focus on the Japanese LED plant factory represented by Toshiba. In recent years, it has reflected the current problems in plant factories and the concern about the future of plant lighting in the future. For reference. Hot-selling: Big factory giants actively enter the field of plant lighting I. OSRAM: LED new products set a new standard in the field of plant lighting Osram Opto Semiconductors recently released a LED prototype that promotes healthy plant growth: Oslon Square Hyper Red, set up plant lighting With a number of new standards in the field, this high-power LED integrates larger chips and has higher radiant flux, providing excellent efficiency for commercial greenhouse plant lighting. Thanks to the improved emission characteristics of this third-generation 2 W-class LED, higher light output and superior corrosion resistance, the Oslon Square Hyper Red plant lighting system will be highly cost-effective. The new high-power LEDs will be more powerful than the previous ones. In addition, one Oslon Square Hyper Red can replace two Oslon SSL LEDs. Moreover, because it uses the same package size as the existing Oslon SSL version, it is easy to replace. The LED is expected to begin mass production by the end of 2017. Plant growth requires two basic elements: water and light. Today, commercial growers can control all stages of plant growth with LEDs of different wavelengths. With the 660 nm wavelength of the Oslon Square Hyper Red prototype, you can control the growth of plants during flowering. Together with the deep blue version of 450 nm and the far red light of 730 nm, OSRAM's Oslon series is enough to cover the entire process of plant growth. According to reports, this high-power LED prototype integrates a 2 mm2 chip for better performance. The developers have adopted the latest technology, with a current of 700 mA and an operating temperature of 25 ° C, the typical radiant power can reach 905 mW, and the radiation efficiency can reach 60%. This means that compared to the current Oslon SSL, the radiated power is increased by 13% and the radiation efficiency is increased by 25%. Oslon Square Hyper Red has a beam angle of 120. Second, Yiguang: A full range of agricultural LEDs to meet the growth of various animals and plants. Yiguang Optoelectronics Co., Ltd. recently exhibited a full range of agricultural LEDs developed in the United States, including various types of high-power, medium-power and Low-power products to meet the needs of various plants and animals in different growing environments, and hope to achieve the goal of maximizing the growth of animals and plants and saving energy. The advantage of Yiguang Agricultural Lighting LEDs is not only to provide the wavelength, power and size according to the time, but also the first company to put monochromatic light into LM-80 test, which effectively ensures the customer's requirements for LED service life. The full range of agricultural LEDs covers the full range of PAR 450nm to 730nm. According to reports, high-power use of special ceramic substrates to improve heat dissipation, EAHP3535 (3.5x3.5x2.03mm) Royal Blue 450nm can be operated to 4.5W can also reach WPE65%, EAHP3535 (3.5x3.5x2.03mm) Deep Red 660nm up to 4.7 PPF to provide the best photosynthesis to accelerate crop growth. At the same time, it also introduced two medium-sized mid-power products, EAHP3030 (3.0x3.0x0.63mm) and EAHP2835 (2.8x3.5x0.65mm), which are lightweight and suitable for plant factories or vertical planting. Customers can apply according to the wavelength, power, wattage and size required for the planting environment.
