The LED light fixture that is used for the plant growth
Technical field
The utility model relates to lighting apparatus, the lighting that the plant illumination of saying so exactly growth is used.
Background technology
The Along with people's growth in the living standard, the demand of corresponding greengrocery plant is increasing, and present domestic the greenhouse gardening that generally adopts becomes a kind of effective means.Yet in order to impel the plant growth, also need throw light on to plant, make plant growth rate fast, healthy development has sufficient photosynthesis.
In traditional agriculture is produced general use the common electrical light source to replenish illumination and white light source covered agrotechnical measure such as colored plastic film change luminous environment with the control facility planting environment in growth and development of plant.But the problem of these measure various degrees, to cause light quality to be handled impure as lacking analysis to concrete spectral component, light intensity is inconsistent, near even or be lower than the light compensation point of plant, the radiation source efficiency is low etc.
Summary of the invention
Based on this, the primary and foremost purpose of the utility model provides a kind of LED light fixture that is used for plant growth, this LED light fixture can light irradiate crops balancedly; Not only crop flowers and solid can be regulated, and the nutritional labeling of plant height and plant can also be controlled.
Another purpose of the utility model provides a kind of LED light fixture that is used for the plant growth, and this LED light fixture helps plant and gives full play to photosynthesis, promotes growth and development of plant; And this LED light fixture also have the life-span long, volume is little, lightweight characteristics.
In order to achieve the above object, the utility model is to realize like this.
A kind of LED light fixture that is used for the plant growth; It is characterized in that this LED lamp includes shell, power supply, fan, LED lamp and lampshade, said shell is positioned at the top or the bottom of this light fixture, is installed with fan on the surface of shell; So that dispel the heat, on the fan or a side be provided with power supply; Power supply is fixed on the substrate, and substrate is provided with a plurality of LED lamps, and has a lampshade to be covered on the LED lamp.
Said LED lamp includes red LED lamp and blue LED lamp, and red LED lamp and blue LED lamp are provided with at interval, are interspersed.Use red LED lamp and blue LED lamp, blue luminous energy promotes the greenery growth; Red light helps to yield positive results and kind of blooming period prolonging, helps photosyntheticly fully carrying out, and helps the growth of plant.
Above-mentioned LED lamp, generally between 4:1-9:1, that the most frequently used is 6:1 to the ratio of its red LED lamp and blue LED lamp, 9:1, these several ratios of 7:3.
Said shell, its position corresponding to fan has louvre, so that heat is distributed fast.
Said lampshade includes lampshade external member and safety glass, and the lampshade external member is covered on the substrate; And the middle part of lampshade external member has an opening; Opening goes out to be embedded safety glass, through safety glass light is transmitted on the plant, can shine plant targetedly like this; Be convenient to giving full play to of photosynthesis of plant, promote the g and D of plant.
Above-mentioned lampshade external member also can select for use transparent material to make, and like acryl, glass, is convenient to light and distributes, and shines on plant.
The utility model is through this LED light fixture, make the illumination wavelengths type of LED lamp abundant, just in time becomes with plant photosynthesis and the spectral region of photomorphogenesis identical; The light that can also concentrate specific wavelength is irradiate crops balancedly; Not only crop flowers and solid can be regulated, and the nutritional labeling of plant height and plant can also be controlled.
And compare with other light sources such as cold white fluorescent lamp, high-pressure mercury lamp and metal halid lamps, LED more can change into photosynthetically active radiation with luminous energy effectively; In addition, it have the life-span long, volume is little, in light weight and be characteristics such as solid-state.
Description of drawings
The explosive view that Fig. 1 implements for the utility model.
The specific embodiment
Below, shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Shown in Figure 1, the LED light fixture that is used for the plant growth that the utility model is realized includes shell 8, fan 7, power supply 6, substrate 3, blue LED lamp 5, red LED lamp 4, lampshade external member 2 and safety glass 1.
Wherein, shell 8 is positioned at the top of this light fixture, and has a plurality of rounded netted louvres on the shell 8, and the shape of louvre is with consistent; Be fixed with fan 7 on the surface of shell 8, so that this light fixture is dispelled the heat.
Be provided with power supply 6 on the fan 8 again, common power supply 6 has a plurality of, and to drive fan and LED lamp, power supply 6 is cascaded, and controls through switch 9.
Power supply 6 is fixed on the substrate 3.Substrate 3 is provided with a plurality of LED lamps, and these a plurality of LED lamps are to be constituted with red LED lamp 4 by blue LED lamp 5, and blue LED lamp 5 is interspersed with red LED lamp 4, is fixed on the substrate, red LED lamp 4 and blue LED lamp 5 common pro rates according to 4:1--9:1.In implementation shown in Figure 1, red LED lamp 4 and blue LED lamp 5 are provided with according to 7:3.
The light of different wave length is different for the influence of photosynthesis of plant, after deliberation, the light that photosynthesis of plant needs, wavelength is about 400-700nm.Thereby a plurality of LED lamps that the utility model adopted, be the combination of selecting blue LED lamp and red LED lamp for use, blue LED lamp sends the light of 400-500nm (blueness), and red LED lamp sends the light of 610-720nm (redness), and is maximum for the photosynthesis contribution.
One lampshade external member 2 is covered on the substrate 3; And the middle part of lampshade external member 2 has an opening; Opening goes out to be embedded safety glass 1, through safety glass 1 light is transmitted on the plant, can shine plant targetedly like this; Be convenient to giving full play to of photosynthesis of plant, promote the g and D of plant.
In a word, the advantage of the utility model is following.
1, LED is as the irradiation of inducing of plant photoperiod, photomorphogenesis.The illumination of specific wavelength can influence flowering time, quality and the duration at florescence of plant.Some wavelength the illumination flower bud number that can improve plant with bloom number; Some wavelength illumination can be lowered into flower reaction, regulated and control bennet length and florescence, help cut-flower production and listing.Because the technical characterictic of LED is convenient to produce single or narrow-band spectrum, can penetrate according to the best illumination of plant growth rhythm dispensing through the LED regulation and control.
2, type of wavelength abundant, just in time becomes with plant photosynthesis and the spectral region of photomorphogenesis identical;
3, frequency spectrum wave width half-breadth is narrow, can make up as required to obtain pure monochromatic light and complex spectrum;
4, the light that can concentrate specific wavelength is irradiate crops balancedly; Not only crop flowers and solid can be regulated, and the nutritional labeling of plant height and plant can also be controlled;
5, system's heating is few, and it is little to take up room, and can be used for multilayer cultivation tridimensional combined system, has realized low heat loads and the miniaturization of production space;
6, compare with other light sources such as cold white fluorescent lamp, high-pressure mercury lamp and metal halid lamps, LED more can change into photosynthetically active radiation with luminous energy effectively; In addition, it have the life-span long, volume is little, in light weight and be characteristics such as solid-state, also reduced operating cost.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
