Description

Plant growth LED flat plate light source
Technical field
The utility model relates to a kind of LED flat plate light source, particularly relates to a plant growth LED flat plate light source.
Background technology
Plant is the high-tech new product that recent five years rises along with LED white-light illuminating with LED light source, it is compared with other light sources such as cold white fluorescent lamp, high-pressure mercury lamp and metal halid lamp: more effectively light energy conversion can be become photosynthetically active radiation, produce better plant light compensation effect; It also has that the life-span is long, volume is little, lightweight and in the advantage such as solid-state.In addition, research shows that LED illumination System can provide spectral power distribution to throw light on uniformly, and the efficiency that its electric energy is converted to plant institute light requirement exceedes 520 times of Metal halogen lamp.Therefore, LED light source obtains and widelys popularize in space plant growing.
Through application testing, plant LED light source is applicable to growth, the Flowering and fruiting of plant very much.The blue light of visible ray medium wavelength range 400 ~ 510nm, Chlorophylls and Carotenoids assimilation ratio is maximum, has the greatest impact to photosynthesis; The ruddiness of wave-length coverage 610 ~ 720nm, Chlorophyll absorption rate is low, has remarkable impact to photosynthesis and photoinductive cycles.And if the light of 315 ~ 400nm, then the Chlorophyll absorption of plant can be caused few, affect photoinductive cycles, stop stem to extend.General houseplant flowers, because of lack natural daylight note along with the propelling of time growing way worse and worse, and to be irradiated with LED light source by the plant of spectrum (light quality combination) needed for use plant, not only can promote that it grows, its florescence can also be extended, improve the quality of flower.This high efficiency light source system is applied on booth, greenhouse etc. agricultural production facility, the drawback of the booth vegetable mouthfeel such as tomato, the cucumber decline caused because sunshine is not enough can be solved on the one hand, winter booth solanaceous vegetables can also be made on the other hand to advance to and go on the market around the Spring Festival, to reach the object that anti-season is cultivated.
But, the existing LED sending red blue wave band promotes slowly to plant growth rate, DeGrain, and because temperature is too high in irradiation process, the heat of light source cannot effectively shed by heat abstractor, may to burn plant, the light efficiency of light source own also can be made simultaneously to reduce, affect the life-span of whole LED.Chinese invention patent CN201210018869.X discloses a kind of LED plant growth down lamp, comprise lamp housing, be located at driving power in lamp housing cavity and LED light source and radiator, LED light source comprises aluminium base and is located at the multiple LED lamp bead on aluminium base, multiple LED lamp bead is number ratio is multiple LED red globe lamp pearl of 7:3 and multiple LED blue-ray light pearl, and the main crest of light that LED red globe lamp pearl and LED blue-ray light pearl send is 370 ~ 390nm, one end face of aluminium base held against heat sink is arranged, and lamp housing is provided with multiple louvre.The light-illuminating of this device can improve the speed of growth of water algae greatly, and its perfect heat-dissipating, service life is longer, but its structure is comparatively complicated.Chinese utility model patent CN201220481410.9 discloses a kind of LED flat lamp, comprise lamp socket, light trough, light-passing board, LED light source module, lamp socket is one-body molded by sheet metal, its plate face is formed and has one group of light trough at least, LED light source module is placed in light trough, light-passing board covers the surface at light trough, it is simple that this device has structure, good heat dissipation and brightness high-technology advantage, its use, installation and maintenance are also more for convenience, but this form of light source bright dipping is uneven, and uniformity is poor, the requirement of plant growth to source mass can not be met.
Utility model content
The purpose of this utility model is just to provide a kind of plant growth LED flat plate light source, to solve the uneven problem of the bright dipping that exists in existing plant LED light source.
The utility model is achieved in that
One plant growth LED flat plate light source, comprises frame, is disposed with substrate, phosphor powder layer and light-passing board from top to bottom in the inner side of described frame, and the lower surface of described substrate is provided with some LED luminescence chips; Described phosphor powder layer is arranged on described light-passing board, and the structure of described phosphor powder layer is that Homogeneous phase mixing has the organic film that can coordinate the fluorescent material producing spectrum needed for plant growth with described LED luminescence chip; Described light-passing board is light transmission glass plate.
The upper surface of described substrate is provided with ultraviolet-proof, and described ultraviolet-proof is coating of titanium dioxide.
Described substrate is glass plate.
The utility model comprises frame, substrate, phosphor powder layer and light-passing board is disposed with from top to bottom in the inner side of described frame, the lower surface of described substrate is provided with some LED luminescence chips, LED luminescence chip is the core component of plant growth LED flat plate light source, be luminous energy by electric energy conversion, LED light source is cold light source, does not have infrared ray and ultraviolet radiation, can not cause damage to the health of staff.Described phosphor powder layer is arranged on described light-passing board, the structure of described phosphor powder layer is that Homogeneous phase mixing has the organic film that can coordinate the fluorescent material producing spectrum needed for plant growth with described LED luminescence chip, can need the fluorescent material being furnished with different ratio according to the different growing stages of same plant with difference floristic.Substrate is glass plate, good heat dispersion performance, without the need to increasing heat abstractor in addition.
The utility model is provided with ultraviolet-proof at the upper surface of described substrate, and described ultraviolet-proof is coating of titanium dioxide.Coating of titanium dioxide can shield external ultraviolet radiation effectively, prevents ultraviolet to the infringement of the LED luminescence chip of this device inside, extends the service life of LED luminescence chip.
