Abstract
The invention discloses a solar-energy-based LED lamp panel capable of reducing nitrate in tomato leaves. The solar-energy-based LED lamp panel comprises a solar energy collecting plate and a plurality of lamp panel bodies. Each lamp panel body comprises a base and a plurality of lamp beads, wherein the base is provided with a plurality of insertion holes. Each lamp bead is inserted into the corresponding insertion hole of the base, and the insertion holes of the base are connected with the positive electrode and the negative electrode of a power supply. The lamp beads include the 680nm red LEDs and the 450nm blue LEDs, wherein the red LEDs and the blue LEDs are evenly distributed in a staggered mode, and the ratio of the red LEDs to the blue LEDs is 6:1. The content of chlorophyll, the content of carotenoid, the content of Vc, the content of total sugar and the content of crude protein are remarkably increased, and the content of nitrate is lowered. Fans are arranged on the side faces to blow heat to the middle, heat is discharged upward through vent holes in the top face, and therefore influences of heat on plants are reduced to the maximum degree.
Description
Technical field
The present invention relates to plant planting field.
Background technology
LED(Light-Emitting Diode), claim again light emitting diode, by three four compounds, as GaAs(GaAs), GaP (gallium phosphide), GaAsP(gallium arsenide phosphide) etc. semi-conducting material make, its core is PN knot.It is to utilize solid semiconductor chip as luminescent material, and when two ends add forward voltage, carrier in semiconductor occurs compound, emits superfluous energy and causes that photo emissions produces visible ray.The LED(luminous intensity >100mcd that can be divided into LED (luminous intensity <10mcd), high-brightness LED (luminous intensity is between 10～100mcd) and the super brightness of general brightness by luminous intensity and operating current) type such as, wherein the ultra-high brightness LED life-span can reach more than 50,000 hours, and light decay is only 30%.The Related product of LED just emerged as far back as the beginning of the sixties in 20th century, 1962 in the world first GaAsP red LED (λ p=650nm) succeed in developing, yellow led starts to occur subsequently, but this one-phase LED light source is only confined to the application in fields such as identifying, view and admire.80 mid-nineties 90s of 20th century, high-brightness LED starts to release, and within 1993, in succession develops again blue and green LED product, and within 1996, White LED is also succeeded in developing.But owing to being subject to the impact of the factors such as brightness, price, LED fails to apply as universal light source very long one period always.Over nearest 10 years, along with in the world to the deepening continuously of semiconductive luminescent materials research, the improving constantly of LED performance, the significantly decline of price, and the releasing one after another of great power LED product, make the universal possibility that becomes gradually of LED.
At present, LED has been widely used in the various fields such as automobile, communication, information, traffic signals, household electrical appliances, illumination and biological medicine.Compare with other artificial light sources such as high-pressure mercury lamp, incandescent lamp, fluorescent lamp, the advantage of LED is: 1. use supply voltage lower, supply voltage is only 2 ~ 24V, and than using, high voltage source is safer; 2. efficient energy-saving, power consumption is only 1/8th of incandescent lamp, 1/2nd of fluorescent lamp; 3. can send the narrower monochromatic light of light wave, as infrared, red, orange, yellow, green, blue etc., but also can need any combination according to difference; 4. the cold light source of low heat generation characteristic, can irradiation at short distance plant, improves space availability ratio; 5. can in the short time, send pulsed light at the utmost point, the response time is fast; 6. little, the compact conformation of volume, stability are strong; 7. pollution-free, as total solids illuminator, not containing metal mercury, shock-resistant, difficult fragmentation, discarded object is recyclable, is a kind of green illumination product; Life-span long, can reach more than 50,000 hours, be tens times of ordinary luminaire.In recent years, along with the continuous innovation of photoelectric technology, LED forward high brightness, target fast energy-saving effect is remarkable cheaply.The performance of this uniqueness of LED light source, for its application in plant planting field provides effective development space.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of LED lamp plate that reduces tomato blade nitrate based on solar energy.Described system comprises solar energy collecting plate and some lamp plates; Described solar energy collecting plate is installed on outside, greenhouse, and collection plate one side windowpane is broached-tooth design; Four summits of opposite side are separately installed with universal joint, and each universal joint is connected with one end of expansion link, and the other end of four expansion links is connected to same fulcrum place; Described expansion link stretches by step motor control; The layering in greenhouse of described lamp plate is placed, and every interlamellar spacing is 1.5 meters; Described lamp plate comprises pedestal and the some lamp pearls that some jacks are set, described lamp pearl is plugged on the jack of pedestal, and pedestal jack connects power positive cathode, and described lamp pearl comprises: 680nm red-light LED and 450nm blue-ray LED, described red-light LED and blue-ray LED are staggered to be evenly arranged, and ratio is 6:1; Described pedestal side arranges some fans, and base top surface is offered passage.
Beneficial effect: solar energy collecting plate can be adjusted different angles as required, reaches the maximum using of solar energy; The windowpane of a side is broached-tooth design on the sunny side, has increased the contact area of sunlight; Expansion link is by step motor control, more accurate; Chlorophyll, carotenoid, Vc, total reducing sugar and crude protein content obviously rise, and nitrate content reduces; Side arranges fan, and heat is blown to centre, and heat is upwards got rid of by end face passage, at utmost reduces the impact of heat on plant.
