Description
Technical field
The present invention relates to a kind of device for cultivating plant tissue, in particular to a kind of mixed light is good, flexibility is high, is easy to group
The device for cultivating plant tissue of dress, function modoularization.
Background technology
It is either still all big to the demand of ornamental flower to the demand of organic vegetable with the raising of modern life level
Width is promoted, but the seasonality of plant growth mutually conflicts with periodical with the demand of people, and as soil is increasingly in short supply, can profit
Effective cultivated area is fewer and fewer, in order to meet people's demand and for solving soil space resource problem, plants
Object factory comes into being and has obtained quick development.
Compared to natural environment, plant factor needs to maximize for the utilization of illumination and space, and in order to simplify plant training
Flow is supported, is saved manpower and time, control cost, modular equipment becomes required.
Existing artificial light source culturing rack or incubator occur on the market, but being mostly will be at the top of LED light incubator
Or below each layer of culturing rack, to carry out illumination to next layer of plant.But due to plant illumination lamps and lanterns
LED lamp bead is mostly red, blue, the polychromes lamp bead such as red, yellow, simply by LED light bar dislocation or lamp bead array structure, it is difficult to reach
Uniform light mixing effect needs increase lamps and lanterns to carry out hoisting light mixing effect to the distance of area of illumination, must thus improve culture
The space availability ratio of frame, and reduce lamps and lanterns to the distance of area of illumination, then light distribution can be caused uneven, it is difficult to ensure that plant has one
The speed of growth and growth cycle of cause so that the plant quality produced by the gross is irregular.The day for announcing is August in 2016 31,
Notification number is the utility model patent of CN205511215U, provides a kind of Fresnel Lenses plant incubator of light-focusing type, institute
The Fresnel Lenses effect stated is optically focused, and to improve the utilization rate of luminous energy in case, but the technology can't reach abundant
Light mixing effect, light distribution be difficult uniformly fully.In addition, the LED light of every layer of installation can generate greatly on last layer culturing rack
The heat of amount influences the growth of this layer of plant.
Invention content
The technical problem to be solved in the present invention is：When plant cultivation device space is limited, light mixing effect is improved, plant is made
Object obtains uniform illumination, it is ensured that plant has the consistent speed of growth and growth cycle, improves the output quality of plant.
In order to solve the above technical problems, the present invention provides a kind of plant tissue culturing racks, including external frame and LED
Chip, the LED chip be equipped with further below mixed light effect two-sided Fresnel Lenses, the two-sided Fresnel Lenses be by
Two single side Fresnel Lenses compositions placed opposite to each other or the two are made of one.
When without two-sided Fresnel Lenses, a part of light is directly mapped to culture bottle bottom of bottle after being projected by LED, and a part is shone
Be mapped in bottle wall through transmission project culture bottle, in this case a part of luminous energy be wasted, and bottom of bottle irradiation brightness and
Colorfulness is uneven, it may appear that the bright half-light spot hot spot different with color.Fresnel Lenses is cut by spherical mirror, can be compared with
Good is calibrated to point light source source of parallel light collimation outgoing, and two-sided Fresnel Lenses combination can also increase the mixed of different colours light
Electrical distance, a variety of colors light pass through multiple reflections and transmission in inner surface of the lens, can substantially increase outgoing with uniform
The uniform intensity degree and color uniformity of light.
As a further improvement on the present invention, upper reflector is covered above the lamp bead of LED chip, LED can be sent out
Light carries out secondary mixed light, and in addition to this, reflector can also constrain the light emitting angle of LED simultaneously, and light low-angle is made to be emitted, and improves
The efficiency of light energy utilization.
As a further improvement on the present invention, the Fresnel Lenses uses polymethyl methacrylate (PMMA) material
It makes, the transparency of PMMA materials is good, and the problem of be less prone to aging, decline so as to avoid light transmittance, substantially increases
The efficiency of light energy utilization of LED light source.
Heat in order to reduce LED light strip influences plant growth, and radiator can be loaded onto on LED chip, in order to
Enhance heat dissipation effect, perforative heat pipe can be installed additional on a heat sink.It further, can also be saturating in LED chip and Fresnel
Between mirror, thermal insulation layer is set.Thermal insulation layer influences illumination in order to prevent, and thermal insulation layer is made using transparent material, preferably used
PMMA materials are made, and most of heat of lamps and lanterns is completely cut off while not influencing light transmission, can effectively reduce light source heat production to plant
The influence of growth.
LED chip selected by the present invention can be red (R) blue (B) dual-colored LED lamp bead of COB encapsulation, can also be two
Kind or a variety of monochromatic LED lamp beads, monochromatic lamp bead may be used two kinds of red (R) blue (B) monochromatic LED lamp bead or red (R) it is green
(G) blue (B) three-primary color LED lamp bead can be directed to different types of plant shoots or tissue, exchange LED core sheet type, to full
The different times of foot difference plant or plant growth, the demand to coloured light.
Further, LED is driven using external pulse width modified tone circuit (PWM), the tune of spectrum may be implemented
Control, to adapt to demand of different types of plant for spectrum.When the bottle cap using one piece or more inlays light source board, by outer
Portion's circuit can also individually control each layer of culture bottle, convenient for regulation and control and mass production.
It is upper on fixed holder that groove can be set as the further improvement of the present invention, the spread pattern of the groove with
Quantity and bottle cap inlay the one-to-one correspondence of the bottle cap card slot on light source board, are respectively intended to place body and bottle cap, groove play stabilization
Effect, increase the stability of single unit system, the mutual collision that can be effectively prevent between culture bottle.
Generally speaking, the invention has the advantages that：Light mixing effect is good, and the efficiency of light energy utilization is high, and spectrum is adjustable, can be applicable in
Different plants for spectrum demand, while assemble again it is flexible, firm, have space-efficient and high heat dissipation effect etc..
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
