Description
Technical field
The present invention relates to a kind of flip chip type plant light compensation LED light source and using the lamps and lanterns of the light source, belong to industrialized agriculture
Lighting field.
Background technique
According to the light physiological property of plant, light radiation is to the photosynthesis of plant, growth and development, morphogenesis and plant generation
Thanking etc. has regulating and controlling effect.The light for being radiated at the different-waveband on plant is different to the physiological effect of plant, thus different-waveband
Beche-de-mer without spike and photosynthetic weight it is also different, and change with the stage of plant variety and growth.Chlorophyll is in plant body
Absorption, transmitting and the conversion of interior responsible luminous energy, carotenoid then exercise luminous energy capture and the big function of Photoprotection two, they
Very important effect is played in photosynthesis.The maximum absorption band of chlorophyll a is 410nm, 430nm and 660nm；Chlorophyll
The maximum absorption band of b is 430nm, 455nm and 640nm.Carotenoid is important accessory pigments, and the luminous energy absorbed is just
It is good complementary with chlorophyll, chlorophyll can be helped to receive luminous energy.Carotenoid absorption band is in the blue violet light area of 400~500nm, algae
The absorption spectrum maximum value of Lan Su is in orange light part, and then absorption spectrum maximum value is in green portions to rhodophyll.
Feux rouges (600nm~700nm, R) and far-red light in the influence of light quality, especially spectrum in illumination condition (700nm~
800nm, FR) effect of ratio (R/FR) of light is increasingly subject to the attention of people.Ratio (the R/ of red and far-red light in spectrum
FR) regulation of the content of plant inner gibberellin (CA), phytomorph are built up, plant height has great influence.Scientist
By the light quantum current density of feux rouges (R) or far-red light (FR) in manual control plant growth environment, change the ratio of R/FR
To adjust the form of plant.When R/FR ratio becomes larger, the stipes spacing of plant becomes smaller dwarfing: otherwise when R/FR ratio becomes smaller
Then plant has the tendency that elongation.
Green plants during growth, needs visible light to carry out photosynthesis.It is well known that, it is seen that light is one
Kind complex light, during the growth process, the demand to the light of the different colours in visible light is also not quite similar different plants.
More and more researches show that the light of different colours is suitably carried out mixed exposure in different proportions, will have
Help the growth of plant.
But it is formal in concrete implementation, in practical application, red LED in light source or remote red LED need to be increased
Quantity, the adjusting of Lai Shixian R/FR ratio, to achieve the purpose that control plant forms；By increase green LED quantity come
Make up the deficiency in spectrum.It is combined generally by the LED light source using multiple and different colors not year-on-year to reach realization
The luminous environment of the different light medium of example, this is highly inconvenient for user, if during combining LED light source, it is different
Mistake has occurred in the ratio of the LED light source of color, is also just difficult to achieve the purpose that plant yield-increasing increases matter.
LED light source in the prior art such as Chinese patent 201180055432.7,201210414873.8, and
201210375582.2 recorded.
But above three patent passes through blue light excitated red fluorescent powder, is simultaneously emitted by red blue light for plant photosynthesis
Effect, but need to realize light by increasing UV LED, green light LED or infrared light-emitting diode
The supplement of ultraviolet light, green light and near infrared light in spectrum；Following deficiency is brought as a result:
First is that important component is lacked in spectrum, such as ultraviolet light, green light or infrared light, it can be in plant photomorphogenesis
There is wretched insufficiency, influences plant growth and development and quality；
Second is that making up plant by increasing UV LED, green light LED or infrared light-emitting diode
Deficiency in biologically effective radiation spectrum, enhancing photosynthesis either adjust light quality ratio, considerably increase LED light source investment
Cost, if the price of feux rouges and UV LED wafer is 5-8 times of blue LED wafers price；
Third is that light efficiency is low due to increasing UV LED, green light LED or infrared light-emitting diode,
Subsequent operation and maintenance cost are greatly increased, heat dissipation cost accordingly also increases, and energy consumption greatly increases；
Fourth is that in photomorphogenesis shared by the spectrum of ultraviolet light (280nm~400nm) and infrared light (700nm~800nm)
Ratio, relatively low in the spectrum of plant biological Net long wave radiation (280nm~800nm), LED light emitting angle is small, so in spectrum
Uniform irradiation design aspect is difficult to reach requirement.Being difficult under the premise of infrared or ultraviolet LED light source number is less will be infrared
Or ultraviolet LED light source uniformly configures, or even if infrared or ultraviolet LED light source angle of flare directive property is adjusted to most preferably, it is ultraviolet
The colour mixture of light, infrared light and feux rouges and blue light is also insufficient, therefore it is uneven that spatial distribution easily occurs.
