According to TrendForce's analysis, the LED plant lighting market will grow substantially in 2020, with an annual growth rate of 41%. This is mainly due to the commercial legalization of hemp in North America and the shortage of food and medicine caused by the global epidemic, which has driven agricultural investment and construction to heat up again, and the demand for plant light has increased.
Plants are so hot, what kind of light do plants need?
We know that plant growth requires photosynthesis, which converts water and carbon dioxide into sugars to provide energy. Different light will directly affect the growth, development, yield and product quality of plants. Plants' demand for light is mainly embodied in three aspects of light radiation illuminance (intensity), photoperiod, and spectral distribution, which is also called the "light environment" for plant growth.
So, how to create a good "light environment"? Today, let's look at the solution of the LED manufacturer Hongli Zhihui.
GMKJ LED cooperates with South China Agricultural University, the Semiconductor Research Institute of Guangdong Academy of Sciences and the supplier terminal of social agricultural solutions for in-depth research and development, to provide customers with the correct combination of key parameters such as spectrum, efficiency, and reliability, and to create good plants for plants. Light environment".
1. Solutions, precise and professional
In order to further improve the effective use of the spectrum, GMKJ LED uses simulation software that simulates the spectral energy distribution of LEDs to simulate the spectrum of different plants and different environments. Research and observe the effects of LED light quality spectrum and illumination mode (photoperiod, light intensity) on the growth and physiology of fruit vegetables, leafy vegetables and high value-added medicinal plants, in order to screen out high-efficiency and energy-saving plant spectrum formulas. The picture below shows the special spectrum plan formulated for the growth needs of some plants.
2. High-efficiency plant lighting LED series products
In response to the growing trend of indoor planting, red light is the main source of supplementary light sources for greenhouses. Vertical farms and plant factories are not exposed to sunlight at all, so plant light sources also need to be supplemented by white light. Therefore, in addition to red light, white light is gradually introduced into applications. Indoor growth lamps that combine red light and white light can best meet the growth needs of different plants.
GMKJ LED provides customers with a full series of rich product lines of plant lighting LEDs, including 390nm (purple light), 450nm (deep blue light), 525nm (green light), 660nm (ultra red light), 730nm (far infrared), ultra-high luminous efficiency white light products, And 2835, 3030, COB for plant lighting. The product size ranges from 2835, 3030, 3032, 3535, COB13.5*13.5, COB28*28 product power covering 0.5-25W.
For red light products, GMKJ's latest C3535 red light product has a radiant flux of 1030mw at 700mA and a PPE of 3.85μmol/J. For white light products, Hongli Zhihui recently launched PCT3032 and 3030 flip-chip white light products. The light flux can reach 40~41lm at 65mA. Under the condition of 5000K and CRI80, the PPE has 3.0~3.23μmol/J. In order to provide higher quality lamp beads, the whole series of GMKJ LED plant lighting products adopt a special coating process, and its anti-vulcanization performance is more excellent.
3. Reliable performance and meet certification requirements
Guangmai LED plant lighting series products have obtained the Q90 report with the advantages of high power and high reliability, helping customers to obtain certification requirements that meet the plant lighting standard V2.0.
Certification Plant Lighting Standard V2.0
1. Photosynthetic photon efficiency (PPE): not less than 1.9μmol/J;
2. Lifetime requirements: Photosynthetic photon flux maintenance rate (PFMP) and far-red light photon flux maintenance rate (PFMFR) PFMFRQ90 are greater than or equal to 36,000 hours;
3. The lamp warranty must be at least 5 years, the power factor must be greater than or equal to 0.9, the total harmonic distortion (current) must be less than or equal to 20%, and the safety certification must be passed. The fan and drive life must reach 50,000 hours.
GMKJ makes use of its superior platform in the packaging field, is market demand-oriented, insists on innovation and breakthroughs, and actively develops plant lighting LED light source products and all-round plant lighting LED solutions that meet market needs. At present, it has designed multiple sets of LED plant lighting solutions. Covers many fields such as household planting, greenhouse planting, plant factory, outdoor greening planting and so on.
GMKJ LED said that in the future, it will continue to increase the basic research and patent layout of plant lighting, expand from traditional functional LED lighting to functional LED bio-optics, and accelerate the response to the market, combining special plants, plant factories, Provide bio-optical LED application solutions with different needs and characteristics such as the plant home market.
