The utility model comprises a power rectifier, a module, a module baseboard, a module circuit and a fixed box, wherein the module circuit is provided with a flasher circuit (including an oscillation circuit) which output is fed to a light emitting diode to generate a light at a special wavelength and enough strength, therefore, the vegetable and fruit in refrigerating box can take natural photosynthesis to preserve fresh. The utility model has simple structure, easy operation, low production cost and better preservation effect of vegetable and fruit.

Description

The photosynthetic antistaling device that a kind of refrigeration case is used

Technical field

The utility model is about the refrigeration environment protection preservation device, particularly a kind of in refrigeration case to the photosynthetic antistaling device of vegetables, fruit.

Background technology

At present, people utilize various preservation techniques to keep the freshness of fruits and vegetables, wherein also favourablely use up cooperation and are used for fruits and vegetables are carried out fresh-keeping, and principle is that its distinctive chlorophyll of plant utilization absorbs energy of the sun, carbon dioxide and water are converted into the organic matter that is rich in energy, and discharge the process of oxygen.This process is extremely complicated, comprises light reaction and dark reaction.Photosynthesis of plants changes along with the variation of luminous intensity, and under low light condition, the rate of photosynthisis of plant nearly all improves along with the enhancing of luminous intensity, i.e. rate of photosynthisis and luminous intensity positive correlation.If but intensity is attenuated to a certain degree, just rate of photosynthisis can't be measured, under this luminous intensity, rate of photosynthisis of plant and respiration intensity equate that luminous intensity at this moment is photosynthetic light compensation point.Growing plants under the luminous intensity below the light compensation point is because respiratory intensity has surpassed rate of photosynthisis, plant can not accumulate organic substance, need a large amount of original organic substances of consumption, so plant only could accumulate organic substance under the luminous intensity more than the light compensation point.But after luminous intensity was increased to certain degree, the increasing degree of rate of photosynthisis can slow down gradually, reach a limit value after, can not increase even improve intensity of illumination more thereupon yet, luminous intensity at this moment is photosynthetic light saturation point.Utilizing photosynthesis fresh-keeping is a kind of good preservation method, but utilize the fresh-keeping device of this way but to be difficult to do light to such an extent that approach the sunlight of nature at present, can't regulate luminosity and reach a suitable fruit and vegetable preservation, not waste the intensity of electric energy again, fresh-keeping effect is bad.

Summary of the invention

The utility model purpose is to solve or improve the deficiencies in the prior art, a kind of fresh-keeping light source of suitable refrigeration case environmental protection and control technology are provided, impel the fruits and vegetables in the refrigeration case to proceed quick photosynthesis, improve vitamin C and chlorophyllous content, thereby prolong storage period.

In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals:

The photosynthetic antistaling device that refrigeration case is used, comprise fixed bin and power rectifier, its structural feature is: be fixed with lampshade on the described fixed bin, modular circuit is fixed on the fixed bin inner chamber by linking together with module substrate, module is installed on the module substrate, and LED is mounted on the module.

The required dc source 5～12V of described modular circuit is provided by power rectifier, is controlled by refrigeration case computer control panel.

Include the flasher circuit or the oscillating circuit of decision LED glow frequency, wavelength, intensity on the described modular circuit.During use, the work of modular circuit is controlled by refrigeration case computer control panel.

Described LED is one or more bluenesss, white, orange, purple, yellow high-brightness LED lamp Chang Liang, one red indigo plant is double-colored or blood orange is double-colored or red and green color or the double-colored highlighted LED lamp of reddish yellow are alternately glittering, and red, green, white, blue four a looks highlighted LED lamp replaces glittering hybrid light source; Perhaps be that single blueness or white high-brightness LED lamp are glittering, one red indigo plant is double-colored or blood orange is double-colored or the highlighted LED lamp of red and green color is alternately glittering, single purple or the glittering hybrid light source of orange high-brightness LED lamp.

Because adopt technique scheme, the preservation device that the utility model provides has so effective effect, promptly can regulate the size of luminous intensity in the photosynthesis, thereby reach the most best luminosity of suitable fruit and vegetable preservation, simple in structure, easy to use, low cost of manufacture.
