Description
Technical field
The present invention relates to a kind of lighting technical field, more particularly to LED plant lamp light adjusting systems.
Background technology
With the fast development of agricultural economy, the cultivated area of hothouse plants expands year by year, and China's chamber planting remains unchanged
Follow traditional mode, automaticity is relatively low, seeks less than the optimum point between costs and benefits, and restricts its economic growth
Factor essentially consist in the yield and qualities of crops.
Visible ray is than one of indispensable important environmental factor during the photosynthesis of plant, growth characters.Wherein
380~760nm of wave band is the most important wave band for determining photosynthesis of plant, can be with using feux rouges, blue light as effective absorption bands
Directly affect the yield and quality of plant.With the fast development of LED illumination, its application on agriculture field is increasingly extensive,
Compared with conventional light source, LED has the advantages such as optional small volume, long lifespan, spectrum, energy-conservation, light efficiency height.
LED plant illuminations are currently in the starting stage, and foreign countries especially PHILIPS, OSRAM etc. achieves certain hair
Exhibition, domestic is even more ground zero, there is presently no unified professional standard, but it is no matter international or domestic, all exist equally
Drawback, once light fixture is produced, what the spectrum of plant lamp light fixture was just to determine, it can only be customized, planted according to plantation demand
The plantation demand of plant person once changes, it is necessary to customizes light fixture again, necessarily causes to waste.In order to improve making for plant lamp light fixture
With efficiency, the planting cost of planting person is reduced to greatest extent, The present invention gives a kind of plant illumination light regulating technology, together
When light modulation is realized by way of system.
The content of the invention
The present invention gives LED plant lamp light adjusting systems, light adjusting system is adjusted by adjusting each paths of LEDs size of current
The photosynthetic photon flux of different light medium（PPF, unit are μm ol/s）, it is possible to achieve the photosynthetic photon flux density of light fixture（PPFD,
μmol/s/㎡）And different light medium（It is red, blue, remote red, white, ultraviolet）The regulation of photosynthetic photon flux accounting, finally realize that light is matched somebody with somebody
The regulation of side so that same light fixture can meet the light demand of different plants.
Meanwhile light adjusting system of the present invention can realize the different controls in multiple greenhouses, and the light fixture in each greenhouse is carried out respectively
Control；The demand difference of the ratio of light quality can also be adjusted different plants, according to floristic difference so as to set
Determine light source formula, the different cycles can also be selected to be controlled light application time.
To achieve the above object, the technical solution adopted in the present invention is：
LED plant lamp light adjusting systems, including host computer, controller, driver is decoded, with the host computer phase and being connected with multiple controls
Device processed, each controller are in series with multiple decoding drivers, each output end for decoding driver by PWM constant currents driving with
LED is in series.
Control can be adjusted to the switch time of LED, luminous intensity, light quality in described controller.
The LED is the LED lamp of two or three of light quality.
The output end of described each decoding driver drives the LED with two kinds of light qualities mutually to go here and there by the constant current of PWM two-way
Connection.
The output end of described each decoding driver is mutually gone here and there by the tunnel constant current drivings of PWM tri- and the LED of three kinds of light qualities
Connection.
Decoding driving each passage drive a kind of LED of light quality respectively, by adjust the electric current of each passage come
Realize the regulation to different light medium content.
The present invention is regulated and controled from the light quality of Plant Light demand, light intensity, photoperiod so that same plant LED can answer
Different plants is used, improves the service efficiency of LED lamp.The light demand of plant mainly includes three aspects：（1）Light quality, i.e.,
Photosynthetic effective spectrum, the photosynthetic effectively spectrum of plant are concentrated mainly on the blue light of 650-660nm feux rouges and 440-450nm,
Different plants for red blue light than demand it is different, be concentrated mainly on 4:1-9:1, in order to which same light fixture is used for into different plants
Thing, the present invention have the adjustable function of red-blue ratio；（2）Light intensity, i.e., photosynthetic photon flux density（PPFD）, the PPFD of different plants
Demand is different, and after the installation site determination of light fixture, PPFD change depends on the photosynthetic photon flux of light fixture（PPF）, this hair
It is bright that there is the adjustable functions of PPF light fixture is applied to different plants；（3）Photoperiod, the photoperiod of different plants is different, in order to
The growth of plant, such as florescence are controlled, or even the photoperiod can be adjusted, the present invention has timing function, comes in real time to planting
Object light, which is shone, to be adjusted.
Compared with prior art the invention has the advantages that：Produced different from LED plant illuminations in the market
Product, the plant LED light adjusting system given by the present invention can be such that same lamp applications are applied to same in different plants
The different growth phases of one plant, most suitable spectrum can be provided for plant, realized to light quality ratio optimal needed for plant
Example regulation, the regulation of intensity of illumination and the regulation of periodicity of illumination, the peak use rate of light fixture is realized, saves planting cost.
Meanwhile chamber planting is managed collectively with host computer, not only facilitate but also quick.
