Firstly, LED lighting is widely applied in this field: for example, it includes plant tissue culture, leaf vegetable production, greenhouse light supplement, plant factory, seedling factory, medicinal plant cultivation, edible mushroom factory, algae cultivation, plant protection, space fruits and vegetables, flower planting, mosquito repellent and so on.
It is reported that the cultivation of plant seedlings, the production of plant tissue culture seedlings, edible fungus production, livestock and poultry breeding industry is expected to become a leading field, with LED light instead of traditional light source. Plant factories and greenhouses are the fastest growing semiconductor lighting fields, with high technical content and strong intelligent and systematic equipment, which is the key to the development of agricultural semiconductor lighting industry.
The fruits, vegetables, flowers, medicines and other products grown by LED plant lighting technology can greatly meet the needs of military border posts, cold and alpine regions, areas lacking water and electricity resources, home office gardening, Marine space personnel, special patients and other areas or groups.
In addition, there are many kinds of LED plant lighting devices suitable for this field, such as LED plant growth lamp, plant growth box, LED plant growth lamp for residential use, mosquito repellent lamp and so on that have been developed and produced in the market. Among them, the common forms of LED plant growth lamp are bulb, light strip, panel light, light belt, downlight, light grid and so on.
Because the LED can emit plant physiology effective radiation of 300 ~ 800 nm range narrow spectrum of monochromatic light, light quality, light source modulation spectrum can be combined, light environment intelligent control, LED light source with environmental protection, energy conservation, volume small, the advantages of the cold light source, low voltage, dc, and therefore has a good reputation, has been praised as the ideal light source of facilities agriculture in the industry.
LED lighting plants belong to the category of agricultural semiconductor lighting, namely using semiconductor electric light source and its intelligent control equipment, according to the light environment demand rule of plant growth and production goals and objectives, using artificial light to create appropriate light environment or make up for the inadequacy of natural lighting, control the growth of plants, in order to achieve "high quality, high yield and stable yield, college, ecological and safe" production target of a kind of agricultural engineering measures.
Basic points to know when entering LED plant lighting industry
1. What is the biggest difficulty?
LED plant lighting is the product of interdisciplinary and organic development of biology, facility horticulture, vegetable science, plant physiology, plant nutrition, biological environmental engineering, LED lighting, intelligent control technology and so on. So it's not enough to be good at semiconductors, plants, intelligent systems, or both. The biggest difficulty in entering the LED plant lighting market is to develop and produce LED plant light sources or lamps with high yield and high quality ecology. It is necessary to solve the development problem of how to integrate the intelligent control of light environment, plant photobiology and LED semiconductor technology.
What does plant photobiology mean?
The study of the laws of plant photobiology is an important basis for LED plant lighting, including the study of the quantitative properties of the light environment (light intensity and photology), quality properties (light quality and spectrum), and luminescence characteristics of electric light source (duty ratio, frequency). Plant photobiology is complex and systematic.
Photonia refers to the types of photonia that act on living things, including visible, UV, and far-red light. In photobiology, we need to understand the following questions:
First, the biological function of light quality, to study the physiological metabolism, molecular biology and proteomics mechanism of single light quality and complex light quality on plant growth, yield and quality;
Secondly, plant species and their light quality adaptability and utilization difference mechanism.
Third, the biological mechanism of the interaction between light quality and other environmental factors;
Fourth, the effective threshold and reference value of the quantity attribute of lighting quality.
In addition, it is also necessary to study the response mechanism of photosynthetic mechanism under weak light, strong light and continuous light.
3. Why do different enterprises have different lighting formulas for the same plant?
The development of LED plant lighting industry is based on the establishment of lighting formulations needed for the growth, high quality and high yield of various plants.
Aiming at high yield and high quality, the light formula is based on the parameter set of the light quality species and their quantitative properties required by the growth and development stages of the characteristic plant species. Each plant and different growth stages of the appropriate light formula is different.
