Description

A kind of LED plant growth light source

[technical field]

The utility model relates to the artificial light sources of plant growth factory green energy conservation, and in particular, the utility model relates to a kind of LED plant growth light source.

[background technology]

At present, the artificial light source of plant factor uses fluorescent lamp more, and the luminous efficiency of fluorescent lamp has risen 50% in nearest 20 years, but compares still lowlyer with high-pressure mercury lamp, also substantially equates with metal-halide lamp.But, no matter be fluorescent lamp, or the present higher high-pressure mercury lamp of luminous efficiency, its energy consumption is all higher, and main cause is the large percentage of infrared in the artificial light source that uses at present and far red light, there is considerable energy to be delivered in environment in the fuel factor mode, in addition, light fixture produces amount of heat and also makes environment temperature rise, and causes air-conditioning temperature-reducing power consumption to increase, cost improves, and raising, the traditional planting that has directly had influence on the seedling productivity effect is free, the limitation in space.

Because the different wave length line is different for the impact of photosynthesis of plant, the light that photosynthesis of plant needs, wavelength is in the 400-720nm left and right; 400-520nm(is blue) light and 610-720nm(red) maximum for the photosynthesis contribution, 520～610nm(is green) light, the ratio that is absorbed by phytochrome is very low.White LED lamp, the most generally use blue core, excite yellow fluorescent powder, on Energy distribution, there are two peak values in the visual white light effect of compound generation thus in the yellow green district of the blue region of 445nm and 550nm, and the 610-720nm ruddiness that plants needs, lack very much, therefore under the white light LEDs irradiation, plant growth is unfavorable.

[utility model content]

The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and providing a kind of provides optimum luminous environment, realizes the LED plant growth light source of plant efficient growth under artificial environment for different plants.

The technical solution of the utility model is achieved in that it is connected with indoor power supply, comprise lamp body, the lamp body end is fixed with a substrate, its improvements are: be provided with the LED wafer that can send varying strength light on described substrate, this LED wafer is comprised of red-light LED wafer and blue-ray LED wafer;

Preferably, the luminous spectral wavelength of described red-light LED wafer is 610-720nm;

Preferably, the luminous spectral wavelength of described blue-ray LED wafer is 400-520nm;

Preferably, described red-light LED wafer equates with blue-ray LED wafer in the situation that power, and its number is than being 9:1;

Preferably, the chromatogram ratio of the light that sends of the light that sends of described red-light LED wafer and blue-ray LED wafer is 5-10:1;

Preferably, described lamp body end also is provided with a lampshade, and this lampshade is inboard for being used for collecting the reflective surface of light;

Preferably, described lamp body is fixed on a lamp holder, and lamp body inside is provided with a driving power, and this driving power and lamp holder, LED wafer are electrically connected;

Preferably, when this LED plant growth light source is used for that plant is carried out light filling, it is 0.5 meter apart from the height of blade;

Preferably, the lighting angle of this LED plant growth light source is 120 °.

the beneficial effects of the utility model are: it is that light (ruddiness) and the wavelength of 610-720nm is the light (blue light) of 400-520nm that LED plant growth light source of the present utility model provides wavelength, wavelength is the absorption that the light (blue light) of 400-520nm is conducive to chlorophyll and carrotene, photosynthesis is had the greatest impact, and the light (ruddiness) that wavelength is 610-720nm has appreciable impact to photosynthesis and photoperiod effect, therefore, LED plant growth light source of the present utility model is very beneficial for the growth of plant, and the number to the LED wafer, chip sends the chromatogram ratio of light and this LED plant growth light source and reasonably arranges apart from the height of plant, can realize plant growth efficiently under artificial environment, produce.
