Plant lighting has become one of the hottest topics in the LED lighting industry in the past two years. Benefiting from the legalization of industrial hemp cultivation in many countries in various countries and the global construction boom of plant factories and vertical farms driven by the epidemic and agricultural intelligence, plant lighting has ushered in unprecedented development opportunities, and the demand for equipment is rapidly promote. Especially LED lamps, compared with traditional plant lighting products, LED lamps used in plant lighting scenes have the advantages of low heat generation, high photoelectric conversion efficiency, long life and adjustable spectrum, and become a new star in the plant lighting market.

Therefore, various LED companies have been aiming at the plant lighting track one after another, with high enthusiasm for investment, and vigorously increasing the layout of plant lighting in order to seize the opportunity in this blue ocean market.

According to the analysis of LEDinside, the Optoelectronics Research Division of TrendForce, the global plant lighting LED market output value will reach 301 million U.S. dollars in 2020, an annual increase of 57%. It is estimated that the output value in 2021 will reach 399 million U.S. dollars, an annual increase of 33%.

Although plant lighting has become a hot topic in the LED lighting industry in recent years, in fact, LEDs have been used in plant growth lighting research as early as 1989. It was not until 1999 to 2000 that the first commercial LED plant lighting product appeared in Japan. Now, red and blue LED lamp beads are widely used in plant lighting.

Nowadays, lighting equipment has been widely used in plant cultivation, but the complexity of the demand for light for plant growth has made the research on the effect of light on plants never stopped.

Initially, people learned from the process of plant photosynthesis that plant growth requires the participation of light. Further research found that red and blue wavelength light can effectively speed up plant growth, and different wavelengths of light such as UV-A ultraviolet light, far red light, and green light also play different roles on plant growth. In addition, different plants also need to adapt to the corresponding light intensity and photoperiod in order to achieve optimal growth. It is not difficult to see that the light formula suitable for the growth of various plants is still being explored.

In order to meet the needs of various plants for light in different growth cycles, companies continue to deepen their research in the field of LED plant lighting and launch products that are more in line with their needs.

Take NationStar Optoelectronics as an example. Its high-efficiency plant lighting LED series products include monochromatic light series LEDs covering different wavelengths of 380-760nm, non-continuous spectrum excited by phosphors, continuous spectrum full-spectrum series and sunlight Type full-spectrum LED products have the advantages of good heat dissipation, long life, and high light quantum flux efficiency.

It is understood that the combination of high PPE white light and 660nm and 730nm devices of National Star Optoelectronics is the first choice of many manufacturers, and it is now used in batches. In response to high cost performance requirements, National Star Optoelectronics provides high-power ceramic 660nm devices, PPE up to 4.25μmol/J at 700mA, which can provide customers with cost-effective solutions and has been highly recognized by many manufacturers.

At present, high-efficiency plant lighting LED products have been used in the cultivation of hemp, fruits and vegetables, and flowers. Among them, the products for hemp cultivation have been mass-produced. LED lighting products suitable for planting fruit trees, flowers and other scenes have also been paving the way for technology in China.

With the continuous expansion of the plant lighting market in the future and the continuous in-depth research of bio-optics by major companies, plant lighting products will be used in more agricultural crop planting or breeding scenarios, and high-quality plant lighting products will contribute to the development of global agriculture. make a contribution.
