Description
Technical Field
The invention relates to a plant growth illumination device and a control method thereof, in particular to a plant growth illumination device for providing high visual safety for workers in a plant illumination environment and a control method thereof.
Background
In the natural environment, plants perform photosynthesis and development and growth by acquiring light components with effective wavelengths in sunlight. However, the natural environment is diverse and has risks of insect damage and the like. Therefore, plant factories that plant plants in closed spaces such as indoor spaces and simulate natural light by artificial lighting lamps have been gradually developed in recent years, and various large enterprises including philips, osram, GE, siemens and the like have entered this field.
Not all of the light of the various wavelengths contained in natural light can be utilized by plants, and essentially only blue and red light can be absorbed by plants. In particular, blue light B (e.g. 460nm) can help the growth of plant roots, with the most significant effect on early plant; the red light R (for example 660nm) is beneficial to the stem and leaf, flowering and fruit growth of plants; far-red FR (e.g. 730nm) is beneficial for controlling plant flowering and in vivo nutrient synthesis. According to the species and the growth stage of the plant, the optimal illumination environment for the plant can be obtained by setting the appropriate wavelengths of the red light and the blue light and the red-blue ratio (B/R) between the red light and the blue light; the ultimate goal is to obtain high and stable yield of plants and high and stable nutritional ingredients, while achieving insect control and other effects.
For example, the following are described in the literature "Lee-e.g.. different Red-blue LED combined light sources influence on watermelon seedling growth and physiological parameters [ J ]. Cucurbita pepo, 2015,28(3): 14-17": for watermelon planting, a fluorescent lamp is used as a reference (the illumination intensity is 150 mu mol. m-2s-1), and the influence of LED combined light sources (7:1, 7:2 and 7:3) with different red light and blue light ratios (R/B) on the growth and physiological parameters of watermelon seedlings under the same illumination intensity is discussed; the results show that the stem renting degree, the fresh quality, the dry quality and the strong seedling index of the watermelon seedlings under the red and blue LED combined light source are all increased, wherein the effects are particularly remarkable under the condition that RB is 7: 3.
Disclosure of Invention
(problem to be solved)
However, in the prior art, little attention has been paid to visual comfort and visual safety of workers working in plant lighting environments because the power of conventional LED lighting lamps is relatively low and the damage to the human vision is limited, and with the recent dramatic increase in power, the damage to the human vision from high-power LED lighting lamps has also increased.
For example, in a plant lighting environment, after workers leave the environment for twenty minutes in work for a long time, all things seen before the eyes are green, and various conditions such as dizziness, nausea and the like may occur.
Blue light among various light components has the greatest harm to the vision of people, macular degeneration caused by the blue light harm has become the most concerned problem for LED illumination, and blindness caused by macular degeneration is ranked first and exceeds cataract, which is the most main factor causing poor vision according to the report of the world health organization. Therefore, how to reduce the influence of blue light on workers is an urgent problem to be solved.
In addition, blue light and red light are the main light species absorbed by plants, and other wavelengths of light also have beneficial effects on plant growth, for example, a low proportion of green light can promote the growth of lettuce, and in particular, 24% of green light can be supplemented on the basis of red blue light to promote the growth of lettuce. Therefore, it is also necessary to supplement some other lights based on red and blue lights. Because the white light contains other components such as red and blue light, green light and the like, the white light is added on the basis of the red and blue light, the light quality proportion of the white light is adjusted, and the spectrum in the whole illumination environment can be adjusted with low cost and high efficiency.
