Description

The plant culture led light source

Technical field

The utility model relates to a kind of led light source, relates in particular to a kind of led light source that is applied to plant culture.

Background technology

It is green why the blade of plant is, be because the chlorophyll of photosynthetic pigments is difficult to absorb green light and green light is reflected, Fig. 5 for extraction from Japanese plant's factory research the chlorophyll abosrption spectrogram, as shown in Figure 5, red (near the 660nm), near the blue 450nm extinction peak is arranged, green (near the 550nm) then is difficult to absorb, plant grows up by photosynthesis, other important light reaction also has the light kenel to produce, this light kenel has low light level reaction and high light reaction, at phytochrome by name, under the running of pigment such as cryptochrome and Xiang Guangsu, be responsible for germination, bloom, cotyledon is carried out, chlorophyll is synthetic, the stem branch is upheld, the growth of plant kenels such as vane thickness adjustment and quality, produce and to draw from the light reaction action spectrum about this light kenel, Fig. 6 for extraction from Japanese plant's factory research plant light reaction action spectrum figure, as shown in Figure 6, present plant light source only adopts red light and blue light.

The utility model content

The utility model only uses red light or also uses blue light in view of known plants cultivation light source, result of study because of chlorophyll absorption spectrum and the light reaction action spectrum of plant, application green light not yet in effect is so propose plant culture led light source of the present utility model.

The utility model provides a kind of plant culture led light source, it is made of shell block body and light source group, this shell block body is provided with a plurality of controllers, and the light source group is provided with a plurality of red light source bodies, a plurality of blue-light source bodies and a plurality of green light source body, and the wavelength of red light source body is 600nm～700nm, the wavelength of blue-light source body is 400nm～490nm, and the wavelength of green light source body is 500nm～560nm, its light source is mounted in the shell block body, and the set controller of this light source group and shell block body electrically connects, and the set red light source body of this light source group, blue-light source body and green light source body are arranged binding in regular turn.

The beneficial effects of the utility model are that red light source body, blue-light source body and green light source body prolonged exposure by the set controller control light source group of shell block body can make and plant the speed of growth lifting of planting thing, reach sound rapidly effect of cultivating.

The specific embodiment

Fig. 1, Fig. 2 are solid and the part section view of plant culture of the present utility model with led light source, and plant culture comprises with led light source:

One shell block body 10, this shell block body 10 is provided with a plurality of controllers 11; An and light source group 20, this light source group 20 is provided with a plurality of red light source bodies 21, a plurality of blue-light source bodies 22 and a plurality of green light source body 23, and the wavelength of red light source body 21 is 600nm～700nm, the wavelength of blue-light source body 22 is 400nm～490nm, the wavelength of green light source body 23 is 500nm～560nm, light source group 20 is located in the shell block body 10, and this light source group 20 and shell block body 10 set controllers 11 electrically connect, and the red light source body 21 that this light source group 20 is set, blue-light source body 22 and green light source body 23 are arranged binding in regular turn, and red light source body 21, blue-light source body 22 and green light source body 23 are permanent bright or glimmer simultaneously with cycles 200～400 μ s (pulse 200 a μ s).

By the cooperation of said structure, finish plant culture led light source of the present utility model.

Fig. 3 is the user mode reference diagram of plant culture of the present utility model with led light source, see also Fig. 3, plant culture is made of shell block body 10 and light source group 20 with led light source, this shell block body 10 is provided with a plurality of controllers 11, and light source group 20 is provided with a plurality of red light source bodies 21, a plurality of blue-light source bodies 22 and a plurality of green light source body 23, and the wavelength of red light source body 21 is 600nm～700nm, the wavelength of blue-light source body 22 is 400nm～490nm, and the wavelength of green light source body 23 is 500nm～560nm, light source group 20 is located in the shell block body 10, and this light source group 20 and shell block body 10 set controllers 11 electrically connect, the red light source body 21 that this light source group 20 is set, blue-light source body 22 and green light source body 23 are arranged binding in regular turn, by the set controller 11 of shell block body 10, the red light source body 21 of control light source group 20, blue-light source body 22 and the 23 permanent bright or flickers of green light source body, light source irradiation is planted plant frame 40 set planting and plant thing 41, the plant speed of growth of thing 41 of lifting is to reach sound rapidly effect of cultivating.

Fig. 4 is the embodiment reference diagram of plant culture of the present utility model with led light source, sees also Fig. 4, and its overall structure is identical with the utility model Fig. 1, Fig. 2, and the top side of having only its shell block body 10 is an arc, to increase another practicality of the present utility model.

Use the comparison that experimentizes of the growth of seedling of germination experimental result in the greenhouse of radish seed and germination, this experiment is the light filling and the night illumination of natural daylight, in per unit area two test blocks are set, a kind of is that continuous twenty four hours is with the three-color LED irradiation with quantity, another kind of be natural light irradiation only, to the 5th day the germination situation in experiment beginning back, and the upgrowth situation of experiment beginning back after the 11 day compares two test blocks, can confirm that the three-color LED irradiation has remarkable result to plant germination and growth, about the photosynthesis under the high light, existing following research: " under high light; even the photosynthesis of blade surface has reached saturation state, near the photosynthetic saturation state that also do not reach of the chloroplaset at the back side, at this moment; if impose red light, this energy is almost with the loss of heat energy form.On the other hand, the leaf green glow that is difficult to absorb also has quite a lot of part to be conveyed to the back side, drives the chloroplaset that does not reach the light saturation state and carries out photosynthesis.Driving photosynthetic person under high light efficiently, is not red light or the blue light that is absorbed by chlorophyll easily, but green light.Plant properly utilizes chlorophyll, and it is all to make light be passed to blade." (physiological society-PCPGALLERY of Japanese plant 2009 VOL.50-4).

On the other hand, under the low light level, reach night, with red, indigo plant of the present utility model and green LED light Continuous irradiation plant, determine that plant (especially cryptogam) growth is had remarkable result, red, indigo plant and green light exist simultaneously, even under the low light level and night, also the plant growth are had good result, even can infer that plant carries out photosynthesis under the low light level, also have function and exist.
