Over the years, the various subdivisions of the lighting industry have become closer to the production and life of the general public. As the "human granary" in the lighting segment, the development of the plant lighting industry has given strong vitality to the construction of people's livelihoods all over the world. In the past 2020, although the new crown epidemic is ruthlessly raging around the world, plant lighting still has a prosperous development trend under the special environment of this year.
Below, China Lighting Network analyzes the development of the global plant lighting industry in 2020 from various aspects such as technical standards, enterprise dynamics, and application trends, and provides valuable experience for lighting professionals who set foot in this industry.
As the global climate continues to change, market demand for exquisite crop cultivation, storage and preservation of fruits and vegetables, and food safety will increase in 2020. In addition, under the influence of multiple factors such as the food crisis triggered by the global epidemic, it will rely on increasing crop growth speed and saving energy. Save water resources and other advantages, plant lighting continues to expand its scope of application in different fields of planting industry. However, under extremely high expectations, as of the beginning of 2020, many plant lighting-related technical standards have still failed to meet the rapid development needs of this industry.
In January 2020, a study by Rutgers University in the State of New Jersey in the United States showed that although LED lighting can enhance plant growth in greenhouses, standards still need to be established to determine the best light intensity and color to help improve horticulture Energy efficiency of lighting products. Researchers of the study said that the latest developments in LED technology provide a variety of lighting options for the gardening industry, but due to the lack of independent data on the performance of the lights, growers cannot easily compare lighting technologies and LED light source options. For this reason, researchers have proposed standardizing product labels so that lamps and lanterns between manufacturers can be compared.
Under such an industry situation, in order to speed up the standardization process of various important technologies of plant lighting, authoritative lighting industry organizations in many countries and regions around the world have taken action in 2020.
In September, the United States DLC released the official version of the plant light V2.0 standard, which updated part of the previous plant light V1.2 standard. On the basis of keeping the requirement of PPE≥1.9μmol/J of V1.2 version unchanged, DLC has added two optional report parameters of 280-800nm photon flux parameter and efficiency parameter. Radiation in this range It is usually related to the growth and development effects of plants. At the same time, the new standard also updates the same LEDs, the electrical, optical, and heat dissipation structures must be the same, different drivers can be included, and different mounting brackets can be included without affecting heat dissipation.
In November, the "Technical Specification for Quality Evaluation of Greenhouse Plant Supplementary Lamps" formulated by the Ministry of Agriculture and Rural Affairs of China was formally implemented, which standardized the performance indicators and detection methods for the quality evaluation of greenhouse plant supplementary lamps.
In terms of performance, the standard sets clear requirements on the three major performance indicators of plant supplementary light products-electrical characteristics, optical characteristics, and lifespan. In terms of electrical characteristics, the standard specifies that the initial power value should be 90% to 100% of the rated power; the specified power factor is ≥ 0.90; in terms of optical characteristics, the standard specifies performance requirements such as photosynthetic photon flux and photon flux efficiency. The regulations require that the initial value of the PPF of the plant supplement light should not be lower than 90% of the nominal value, the PPE of the high-pressure sodium lamp should not be lower than 1.0 μmol/(s·W), and the PPE of the LED lamp should not be lower than 1.5. μmol/(s·W).
The standard also requires that the estimated or measured life of the plant supplementary lamp based on the maintenance rate of photon flux should not be less than 90% of the rated (nominal) life, and stipulates that the estimated or measured photon flux maintenance rate of the high-pressure sodium lamp is not less than 20,000h 70%, the LED lamp’s estimated or measured 30000h photon flux maintenance rate is not less than 70%. In addition, the standard specifies corresponding detection and calculation methods for different performance indicators.
With the release and implementation of more technical standards, various technical gaps in the plant lighting market around the world will be filled, so that more users can have a basis in the procurement of plant lighting products, and promote a healthier global plant lighting industry.
With the continuous improvement of various technical standards, in 2020, many powerful lighting companies around the world will bring more product technological value to plant lighting users through technological innovation, equity investment, and strategic cooperation.
