LED plant lighting source development trend

- Jul 19, 2019-

  In recent years, LED has gradually entered the lives of ordinary people. It is not difficult to see LED in various fields of general lighting. LED has advantages that cannot be replaced by traditional lighting, and also has a larger development space. The evolution of lighting market based on semiconductor technology has spawned many new growth opportunities, one of which is plant lighting. LED plant lighting is also widely recognized for its advantages, such as increasing crop growth, saving up to 75% energy and 90% water. In the context of global climate change, market demands for sophisticated crop cultivation, aquaculture, food storage and preservation, and food safety are driving the growth prospects of the plant and horticultural lighting market.

  At present, the general lighting market competition has become increasingly heated, LED plant lighting is regarded as a new development space, many LED related enterprises in the field of plant lighting have accelerated the layout in advance.

  From a technical perspective, the improvement of light efficiency and energy efficiency is the key to substantially reduce operating costs. It is an inevitable trend of fine agriculture in the future to adopt LED instead of traditional lamps and dynamically optimize and adjust the light environment according to the light formula requirements of plants from seedling stage to harvest stage. The corresponding light formula is developed according to yield and quality. In terms of yield improvement, it can be cultivated by stages and regions in combination with light formula according to the development characteristics of plants, so as to improve the production efficiency and yield of each stage. In terms of quality improvement, nutrient content, soluble sugar and other functional qualities can be improved by means of nutrition regulation and light regulation. Plant lighting is an interdisciplinary system engineering, in which light source is a crucial link. LED based on its luminous principle, with spectrum can be freely combined, high color purity, color rich and other advantages. For LED light sources, with the same PPF value, the composition of the spectrum can be different, and the effect produced for different plants or at different growth stages of the same plant can also be different. Simply pursuing PPF value cannot achieve the optimal plan of plant growth. Therefore, under the requirements of more specialized market segments, the future plant lighting will put forward new requirements for LED light source, that is, how to achieve effective PPF. This requires LED suppliers to collaborate with other disciplines to develop more targeted light sources. The packaging types of plant lighting LED will also be more diverse, to meet the needs of various plant lighting, from family type entry level to plant factory professional level all coverage, to achieve the optimal solution of the information price ratio.

  It is believed that in the near future, with the continuous development of plant plants, the market penetration rate of LED plant lighting will gradually increase, the organic combination of technology and business, the global market has entered the outbreak period, in the next 20 years, China will become the world agricultural semiconductor lighting technology and equipment industry and its application power and power. LED light source of plant lighting will develop further along with the gradual specialization of the industry and move towards a more targeted direction.
