Description
Technical field
This utility model relates to a kind of illuminator, is specifically related to a kind of booth LED illumination controlled based on PLC
Device.
Background technology
Plant growth and development process is extremely complex biosis, is not only decided by that the heredity of plant self is special
Property, also affected by external environmental condition.Light as the energy source of photosynthesis of plant, its intensity for
Growth and development of plants has significant effect. and for majority of plant, light quality refers to the light of illumination suffered by plant
Spectrum composition, different spectral bands are different on the impact of plant. and plant passes through internal various pigmentary system, sensing
The light of different wavelength range, the growth promoter of regulation plant and metabolism.Substantial amounts of research shows HONGGUANG and blue light
It is the most important two kinds of spectrum of plant growing.HONGGUANG affects the leaf expansion of plant, the elongation of dry matter accumulation stem.
Blue light affects the blade of plant and the growth of stem.
At present plant light compensation field mainly use fluorescent lamp as artificial light source, by changing the composition of fluorescent material,
Change the peak ranges of fluorescent lamp spectrum.The most also use high-pressure mercury lamp and sunlight color dysprosium lamp etc..These light sources are
According to human eye to selected by the adaptability of light, wavelength the most unnecessary in its spectrum, it is not necessary to crop
Growth has facilitation.And the heat of these light sources generation and infra-red radiation are the most, need to use optical filter
Or heat absorbing filter is by spectrum narrowing, to obtain satisfactory spectral distribution.Cannot according between Different Crop,
Field actual light intensity and the composition of spectrum, accurately simulate.And the spectrum of traditional plant growing light supplement light source
It is all continuous complex spectrum, it is impossible to the parameters such as red blue light matter ratio are regulated and controled, it is impossible to according to the need of plant self
Ask and carry out light filling, have quite a few spectrum to be wasted, cause light filling efficiency low.And these are all hot light
Source, surface temperature is higher, causes plant growth environment temperature to raise, and is unfavorable for plant growing, needs to use greatly
The refrigeration plants such as power fan, air-conditioning, cause operating cost to increase.Conventional light source contains some to plant simultaneously
The material that growing environment is harmful, containing the harmful substance such as hydrargyrum, lead in such as fluorescent lamp.
Domestic the most not yet have the equipment using combination LED array light source simulation special spectrum to carry out plant culturing.
When using LED array to cultivate light source as spatial plant, mainly select fixed spectrum wave band.This light source
Device is although it is contemplated that the peculiar spectrum of plant growing, but cultivating light source is fixed spectrum, does not possess spectral component
Regulatory function.
Although common LED plant growth lamp has energy-conservation, pollution-free, the advantage of life-span length, but mostly can only letter
Single control and the good red blue proportioning of customization, for LED light matter, light application time, radiant illumination distribution and environmental feedback
The comprehensive regulations of aspect such as regulation also do not have the product of maturation to occur.The shortcoming of LED is that output spectrum is narrow simultaneously,
Need at least could be met the growth needs of plant by blue light and two kinds of LED combination of HONGGUANG.
