Description

A kind of RBW Colour mixture plant growing LED Lamp

Technical field

The invention belongs to LED illumination technology, particularly relate to a kind of RBW colour mixture plant growing LED.

Background technology

nullPhotosynthesis is the most important chemical reaction of the earth，It it is the basis depended on for existence of all living things，The most photosynthetic motive power，Light quality and the important attribute of spectral composition light，The wave-length coverage of visible spectrum is 380-780，It is ultraviolet light that wavelength is shorter than the light of 380nm，The light being longer than 780nm is far red light，In natural environment，Shining plant spectral composition is to be continually changing，During the cloudy day, blue light is many，The morning of fine day and at dusk HONGGUANG are more，Illumination at noon very by force and is white，Neglect the most cloudy fine weather spectral component the most changeful，Pollution now with air，The impact of haze reduces with the continuous of the ozone concentration of air，The ultraviolet radiation that earth's surface accepts constantly increases，Sunshine, natural law deficiency light quality became the continuous minimizing of the impact ozone concentration with air，The continuous increase of the ultraviolet spoke that earth's surface accepts，Sunshine, natural law deficiency light quality became the key factor affecting photosynthesis of plant.In agricultural planting, plant growth lamp has begun to the facility cultivation for crop, and the LED of different light medium is carried out coordinate plant growth as non-chemically means.But the light quality of plant growth lamp the most on the market is fixing wavelength and independent individuality, is different for the light quality needed for the growth stage that different plants is different.

At present, LED light emitting diode obtains extensive concern and the accreditation of various circles of society owing to having the advantages such as low, the environmental protection and energy saving of power consumption, the energy-saving and emission-reduction policy that numerous relevant active response countries of production firm propose, the research and development and popularization of LED are made that greatly input, many companies all have developed integrated LED module, the part but existing LED module comes with some shortcomings: LED module light quality is single and mixed light irradiates uneven, it is impossible to meet plant growing；LED module is circular luminous intensity distribution, projects circular light spot, and it is high that the luminous intensity distribution of every square metre repeats area, and energy dissipation is serious；In LED module, substrate uses the conventional aluminium substrate that reflectance is low, there is the problem that light efficiency is low, and thermal resistance is high, and heat dispersion is the most bad, causes the reliability of LED module to be substantially reduced.

Fixed wave length for above-mentioned plant growth lamp, it is impossible to be adapted to the light quality in different plant growing stage, it is desirable to provide the product of a kind of energy-saving many light qualities, solve enclosed environment or the illumination of natural environment or light filling problem, it is ensured that the safe and healthy growth of plant.

Summary of the invention

The defect existed for above-mentioned prior art and deficiency, it is an object of the invention to, a kind of RBW colour mixture plant growing LED is provided, this module has the advantages such as the combination of many light qualities, uniform mixed light and rectangle luminous intensity distribution, can be widely applied to the fields such as plant illumination, booth light filling, plant experimental, vegetable nursery.

In order to realize above-mentioned task, the present invention uses following technical solution:

A kind of RBW colour mixture plant growing LED, it is characterised in that this LED at least includes a rectangle LED module or triangle LED module；Described rectangle LED module includes a plurality of square shaped cells, each described square shaped cells is made up of four lamp bead, described lamp bead is red, blue or white luminous source, described four lamp bead lay respectively at four summits of described square shaped cells, a plurality of described square shaped cells closely arrange formation rectangular configuration, share described lamp bead between adjacent described square shaped cells；Described triangle LED module includes a plurality of equilateral triangle unit and right angled triangle unit, each described equilateral triangle unit and right angled triangle unit are made up of three lamp bead, described lamp bead is red, blue or white luminous source, described three lamp bead lay respectively at three summits of described equilateral triangle unit and right angled triangle unit, a plurality of equilateral triangle unit closely arrange formation edge and have rectangular configuration jaggy, described breach is filled by right angled triangle unit, described lamp bead is shared between adjacent described equilateral triangle unit and right angled triangle unit.

In above-mentioned plant growing LED, this LED can realize combination and the distribution of four kinds of light quality ratios, is respectively directed to universal, flower-type, Vegetable-type and the illumination of kind subtype:
