Description

A kind of light supplementing lamp for plants

Technical field

The utility model relates to a kind of light supplementing lamp for plants.

Background technology

Along with the increase of world population, the minimizing in agricultural land, the various technology that can increase crop yield becomes most important.Wherein an important technology utilizes various artificial light sources to carry out light filling to plant exactly, thus reaches the object increasing photosynthesis of plant, change plant growing cycle, improve output.

Traditional plant light compensation technology adopts incandescent lamp or electricity-saving lamp, and luminous efficiency is low, wastes a large amount of electric energy, also greatly improves light filling expense.Moreover, traditional incandescent lamp or the luminescent spectrum of electricity-saving lamp are usually wider, this makes the luminous intensity in unit wave band greatly reduce, and usually only accounts for the sub-fraction of its luminescent spectrum for the spectral region strengthening photosynthesis of plant or regulate the photoperiod useful.So not only power consumption is high but also usual light filling effect is unsatisfactory for traditional incandescent lamp or electricity-saving lamp.

Summary of the invention

For the deficiencies in the prior art, the light supplementing lamp for plants of light filling efficiency while that the purpose of this utility model being to provide a kind of can reducing costs, can be improved.

For achieving the above object, the technical solution adopted in the utility model comprises:

A kind of light supplementing lamp for plants, described light compensating lamp comprises the light source that peak wavelength is the light source of 634 ± 15nm, the light source of 660 ± 15nm and 730 ± 15nm.

The beneficial effects of the utility model main manifestations is:

Because the utility model have employed the efficient LED of special emission wavelength, its luminous efficiency is apparently higher than traditional incandescent lamp or electricity-saving lamp; Moreover, LED makes it have very narrow luminescent spectrum due to characteristic itself, thus high luminous intensity can be produced in specific wavelength band, by selecting different LED combination to improve luminous intensity in some or several wave band targetedly, thus the effect of getting twice the result with half the effort is reached to the specific light filling demand of specified plant.

Accompanying drawing explanation

Fig. 1 is the Facad structure schematic diagram of the utility model one embodiment.

Fig. 2 is the wavelength in the utility model is the light source of 634nm and the comparative result schematic diagram of incandescent lamp luminescent spectrum.

Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, the utility model is more specifically described.

As shown in Figure 1, a kind of LED light supplementing lamp for plants, the light source 2 that described light compensating lamp comprises light source 1 that peak wavelength is 634nm, peak wavelength is 660nm and peak wavelength are the light source 3 of 730nm.

The comparison diagram of Fig. 2 to be light compensating lamp peak wavelength be 634nmLED light source and incandescent lamp luminescent spectrum.As shown in Figure 2, peak wavelength is that the luminescent spectrum width of 634nmLED is much smaller than incandescent lamp.For a certain chrysanthemum, the illumination of peak wavelength 634nm can change its blooming cycle significantly.Because the luminescence of this LED all concentrates on this wave band, all light is all effective to the blooming cycle changing chrysanthemum.And for incandescent lamp, the light of 634nm wave band only accounts for total luminous sub-fraction, a large amount of illumination has all slatterned.So carry out light filling with 634nmLED, only need very little power, save electric energy and light filling expense in a large number.

The part of the present embodiment adopt peak wavelength be the LED of 634nm ± 15nm wave band as light compensating lamp light source, for changing a kind of blooming cycle of chrysanthemum.

It is the LED combination of 730 ± 15nm that the utility model can also adopt peak wavelength to be 660 ± 15nm and peak wavelength, phytochrome in plant is changed into far-red light type (Pfr) active on physiology by the ruddiness of 660nm, and the far-red light of 730nm then changes sluggish ruddiness type (Pr) on physiology into far-red light type (Pfr).Phytochrome can trigger the formation (synthesis or activation) of stimulus of blooming.It is generally acknowledged, no matter be short day plant (corn, soybean, Chinese sorghum, begonia, wintersweet etc.) or long day plant (wheat, barley, rye, rape, golden glow, camellia, sweet osmanthus, henbane seed etc.), it blooms all relevant with the ratio of Pfr and Pr.For short day plant, at the end of the photophase, Pfr/Pr ratio high (because by day, ruddiness ratio is large, is conducive to the formation of Pfr), the synthesis of stimulus of blooming is stoped.After proceeding to night, Pfr reverses to Pr, and Pfr/Pr ratio diminishes.When this value is to certain level, will trigger the metabolic process guiding stimulus of blooming to be formed, the one-tenth flower reaction of short day plant just can occur.As the dark phase by ruddiness is interrupted, Pr converts Pfr to, and Pfr/Pr ratio raises, and namely the formation of stimulus of blooming stoped.For long day plant, form stimulus of blooming, require higher Pfr/Pr ratio, this ratio can obtain at the end of the long photophase.If under short-day, the dark phase is long, then Pfr changes Pr into, or Pfr is damaged, and Pfr/Pr value does not reach higher level, and stimulus of blooming just can not be formed.The ruddiness of dark phase is interrupted, and Pfr/Pr value can be made again to improve, and the stimulus that makes to bloom is synthesized, and long day plant just can be bloomed.Therefore, the utility model can be used for the florescence of effective regulating plant.

The utility model can also adopt the combination of three kinds of LED, comprises light source, the light source of 660 ± 15nm, the light source of 730 ± 15nm that peak wavelength is 634 ± 15nm.By the change regulating the relative luminous intensity of three kinds of LED can simulate four seasons solar irradiation, and then regulate the growth cycle of some plants.

The efficient LED that the utility model adopts luminescent spectrum narrow, its luminous efficiency, light filling successful are higher than traditional incandescent lamp or electricity-saving lamp, and by the illumination selecting different LED combination can improve a certain wave band targetedly, thus the effect of getting twice the result with half the effort can be reached.

The LED that the utility model use luminescent spectrum is narrow, efficiency is high is as the light source of light supplementing lamp for plants, and peak wavelength can be selected to be the LED of 634 ± 15nm or the light source that is made up of the LED of peak wavelength to be the LED of 660 ± 15nm and peak wavelength be 730 ± 15nm according to the specific light filling demand collocation of specified plant, to reach targeted and efficient light filling effect, really accomplish to shoot the arrow at the target.

Light filling is carried out, because luminescence concentrates on this specific band, so only need very little luminous power namely can meet light filling demand owing to have employed the extremely narrow LED of luminescent spectrum.If adopt traditional incandescent lamp or electricity-saving lamp, because luminescent spectrum is too wide, the intensity of illumination in each wave band is very weak, and this reaches the effect same with LED light supplement lamp with regard to exigent whole lamp power.Moreover, use traditional incandescent lamp or electricity-saving lamp to be difficult to regulate the relative intensity of 660nm and 730nm wave band, thus effectively can not simulate the change of four seasons solar irradiation, can not the growth cycle of effective regulating plant.

Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, deduce other combining structure, and all these be changed or replace the protection domain that all should belong to the utility model claim.
