Description
Technical field
The present invention relates to a kind of LED plant growth lamp, particularly a kind of LED plant growth lamp with continuous spectrum.
Background technology
Only green plants realizes the necessary condition of photosynthesis, plant rudiment, to grow and each stage of fruit of blooming, formed all needs illumination.Since 10000000 year, green plants all absorbs energy and realizes photosynthesis from sunshine.And sunshine is a kind of light of continuous spectrum.Different plant, by the needs in each stage of its life, intercepts the light of required wavelength, is not only blue light and ruddiness from sunshine, also needs the light of other wavelength a small amount of.
The appearance of industrialized agriculture and modern agriculture factory proposes the demand to plant growth illumination artificial light sources.The light that photosynthesis of plant needs, wavelength is between 400 ~ 700 nanometers (nm); And the blue light of wavelength between 400 ~ 500 nanometers (nm) and the ruddiness of wavelength between 610 ~ 720 nanometers (nm) maximum for photosynthetic contribution.The mode that current LED plant growth lamp many employings red-light LED combines with blue-ray LED.But the plant growth lamp of this red blue light combination, because do not have continuous print spectrum, it can only play good facilitating effects in the growth of some growth phase to plant of plant, but can not meet the demand of plant to other wavelength light, cause some nutriment to lack, affect quality.
Summary of the invention
Main purpose of the present invention is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, cost is low, and wavelength has the LED plant growth lamp of continuous spectrum between 430 ~ 680 nanometers (nm).
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the LED plant growth lamp with continuous spectrum, and it comprises LED light source lamp pearl group, LED light source substrate, radiator, the driving power that matches with light source.Light source substrate can be aluminium base, ceramic substrate or other heat-conducting substrate.LED light source lamp pearl group is made up of warm white LED and red-light LED.
Described warm white LED colour temperature is below 4000K.It is by emission wavelength be 420 ~ 490 nanometers (nm) blue chip on add and cover fluorescent material and form.The blue chip of preferential employing 450 nanometer (nm) and 470 nanometers (nm).Wherein fluorescent material is that the YAG fluorescent powder of gold-tinted adds the fluorescent material that luminescence peak is green glow and is mixed with luminescence peak, and it is 5%-30% that green light fluorescent powder accounts for fluorescent material gross weight ratio.Described lamp pearl also comprises the red-light LED of at least one emission wavelength at 620 ~ 680 nanometers (nm), as the red-light LED of to be emission wavelength be 660 nanometers (nm) and 640 nanometers (nm) preferably adopted.
The LED lamp bead group applying this fabrication techniques can obtain emission wavelength from the continuous spectrum in 430 ~ 680 nanometers (nm) scope.It respectively has a peak value to meet the needs of chlorophyll to visible absorption in red light district and blue light region.There are again gold-tinted and the green glow of certain energy proportion simultaneously, meet plant needs in every respect.
Lamp pearl is arranged in aluminum-based circuit board with interleaved mode, is electrically connected each other.Can be link by color grouping, also can always connect.Can contact and connect or go here and there and combine.Aluminum-based circuit board is fixedly connected with on a heat sink.
Input and the civil power of driving power connect, and the voltage of output, electric current and light source match.Driving power is intelligent dimming power supply or the fixing power supply exported.Intelligent dimming supply unit, can, by wired or wireless mode, regulate whole light strong and photochromic, also can be designed as ruddiness and warm white tunable optical respectively.
The beneficial effect of this technology: first is energy-conservation; Compare with traditional fluorescent lamp, electricity-saving lamp, the spectral power distribution of the light of the lamp generation of this fabrication techniques more meets the needs of photosynthesis of plant.Main light energy all concentrates red spectral band and blue wave band, and other wave band proportion is very little, so energy-saving effect is obvious.Second is compare with the plant growth lamp only adopting red blue-ray LED to make, and the light fixture of this fabrication techniques has abundanter wavelength can meet the demand of plant to other wavelength light, and light filling better effects if, growth quality is higher.3rd is that cost is low, and lamp pearl kind used is few, and is all that on market, batch is on sale.Price is low, and buying easily.

Fig. 1 is that lamp pearl arranges in a linear fashion, is applicable to making Straight LED plant growth lamp.
Fig. 2 is that lamp pearl is arranged in a straight line with multirow.
Fig. 3 is that lamp pearl arranges with toroidal, is applicable to making PAR lamp, bulb lamp series vegetable growth lamp.
Drawing illustrates: 1-aluminum-based circuit board; 2-emission wavelength is the red-light LED of 625 nanometers (nm); 3-emission wavelength is the warm white LED of 450 nanometers (nm); 4-emission wavelength is the red-light LED of 660 nanometers (nm); 5-emission wavelength is the warm white LED of 470 nanometers (nm); 6-emission wavelength is the red-light LED of 640 nanometers (nm).
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, the warm white LED in this technology has two kinds, and the warm white LED 3 of the first to be LED chip centre of luminescence wavelength be 450 nanometer (nm), the second is LED chip centre of luminescence wavelength is 470 nanometers (nm) warm white LED 5.Chip is coated with the mixture of yellow fluorescent powder and green emitting phosphor and silica gel, the content of green powder accounts for the 5%-30% of powder total amount, and form warm white LED, its correlated colour temperature controls at below 4000K, depending on required blue light ratio.Correlated colour temperature lower blue light proportion is also less.
In this example, red-light LED used has three kinds.The first is emission wavelength is 660 nanometers (nm) red-light LED 4, and the second is emission wavelength is 640 nanometers (nm) red-light LED 6, and the third is emission wavelength is 625 nanometers (nm) red-light LED 2, encapsulates by transparent silica gel.
All LED are arranged in one piece of aluminum-based circuit board 1, and aluminium base is connected with radiator again.Driving power has five tunnels to export, and every road connects a kind of emission wavelength.Namely 450 nanometers (nm) chip does a road of warm white, 470 nanometers (nm) chip as the second tunnel of warm white, 625 nanometers (nm) chip, 640 nanometers (nm) chip and 660 nanometers (nm) chip road separately.Every road can regulate light intensity by wired or wireless mode.If do not need light modulation, then lamp pearl can be powered with a road or a few road after electrical combination.
