Description
Technical Field
The present invention relates to a server-based plant-growth illumination apparatus having an optical signal and a control method thereof, and more particularly, to a plant-growth illumination apparatus providing a server-based optical signal to a worker in a plant lighting 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.
When the FR (R/FR) ratio of red light (R) and far-red light is increased, the stem node spacing of the plant is reduced, and the plant is dwarfed; on the contrary, the plants tend to elongate. The change of the R/FR ratio has different degrees of influence on the differentiation of axillary buds, the chlorophyll content, the stomata index, the leaf area and the like besides the influence on the plant morphology. The R/FR ratio has become an important evaluation parameter for controlling the plant morphology. In the past decade, researchers at home and abroad have conducted a great deal of research work on techniques for adjusting the R/FR ratio to control plant morphology. The method of increasing the proportion of red light or far-red light by supplementing light with an artificial light source is widely applied to actual greenhouse and tissue culture production. For example, a high-pressure sodium lamp is switched on timely, the proportion of far-red light FR is increased, and the elongation of the stems and leaves of the plants is promoted.
Disclosure of Invention
(problem to be solved)
The ratio of the number of red light to far-red light photons (R/FR) in the spectrum has an important influence on plant configuration and plant height adjustment. Among the LED light sources, the red LED and far red LED light sources are more likely to influence the photomorphogenesis and growth development of the tissue culture seedlings than fluorescent lamps. The ratio of R/FR can be flexibly changed according to needs by adjusting the number of the red LED and the far red LED light sources. However, the existing LED plant growth lamps are all plant LED growth lamps manufactured by a white light LED light source or a mixture of red and blue light LED light sources or a mixture of red, blue and white LED light sources. Because the red light luminous efficiency is low, in order to meet the spectrum and illumination intensity required by a plant photosynthetic pigment system, the plant LED growth lamp needs more red light LED light sources, the lamp power is high, the light quality distribution is uneven, and the cost is increased rapidly.
The problem in the process of supplementing infrared light by using a high-pressure sodium lamp is that 1) the ratio of R/FR is not easy to accurately control; 2) since the high pressure sodium lamp generates a large amount of heat during its operation, attention should be paid to prevent the generation of a high temperature environment.
