Further, described collector lens scioptics mount support is fixed on the described LED lamp pearl.
The optically focused LED plant growth lamp of the utility model embodiment can effectively shine by very large-area carrying out to plant, more effectively with light-ray condensing, makes luminous energy change into photosynthetically active radiation.In addition, it have the life-span long, volume is little, in light weight and be characteristics such as solid-state.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, the optically focused LED plant growth lamp of the utility model embodiment is proposed, this optically focused LED plant growth lamp comprises stand frame 1, aluminium base 2, one or more LED lamp pearl 5, collector lens 6 and translucent cover 7.
Above-mentioned one or more LED lamp pearl 5 is fitted on the aluminium base 2, and this LED lamp pearl 5 can be white LED lamp pearl, red-light LED lamp pearl or blue LED lamp pearl, any combination that can above-mentioned three kinds of LED lamp pearls.
The combination of preferred red-light LED lamp pearl and blue LED lamp pearl, because the light of different wave length is different for the influence of photosynthesis of plant, wavelength promotes the greenery growth at the blue luminous energy of 440-470nm, and wavelength helps to yield positive results and kind of blooming period prolonging in the red light of 625-660nm.The combination of the LED lamp pearl of blue 440-470nmLED lamp pearl and red 620-660nm just can provide plant required light, and on visual effect, the plant lamp of red blue combination presents purple.
The quantitative proportion of above-mentioned red-light LED lamp pearl and blue LED lamp pearl is generally between 1: 1 to 9: 1, according to different plant independent assortments.Because plant is subjected to the red light irradiation time just can promote organic accumulation more than 4 hours, promote photosynthesis and make oxygen every day, and blue light shines plant more than 4 hours every day, can promote the accumulation of organic protein, growth to seedling has great help, therefore, when the combination of adopting red-light LED lamp pearl and blue LED lamp pearl, particularly when the quantitative proportion of red-light LED lamp pearl and blue LED lamp pearl be between 1: 1 to 9: 1 during scope, can effectively promote plant to grow.
Further, can be with red-light LED lamp pearl and the even cross arrangement of blue LED lamp pearl, the irradiation that plant is subjected to is even, and the power of above-mentioned LED lamp pearl can adopt the LED lamp pearl of different capacity as required, as using the LED lamp pearl of 1W.
Collector lens 6 is arranged at the place ahead of described one or more LED lamp pearl 5, but the scioptics mount support with collector lens 6 better close positioning on LED lamp pearl 5.The collector lens 6 of different optically focused angles can be set as required, as the collector lens 6 of different optically focused angles is set on the LED of different colours lamp pearl 5, or on the LED of diverse location lamp pearl 5 the collector lens 6 of different optically focused angles is set, for example in the aluminium base center or the optically focused angle of the collector lens in LED lamp pearl 5 the place aheads of position, edge be the 45-60 degree.
Above-mentioned translucent cover 7 is arranged at collector lens 6 the place aheads, can adopt high-light transparent PC material, and its light transmittance improves the utilization rate of light up to more than 92%.
Above-mentioned aluminium base 2, LED lamp pearl 5, collector lens 6 and translucent cover 7 are fixed in the stand frame 1, then by the both ends open sealing of location aluminium flake 3 with stand frame 1, with connector fixing and lockings such as screw location aluminium flake 3.This stand frame 1 can be the heat radiation aluminum pipe, adopts 6063 aluminium alloys, has good thermal conductivity, and its heat conduction system can reach more than the 200w/m.k.
The optically focused LED plant growth lamp of the utility model embodiment is about 0.5-1 rice apart from blades height generally when giving the plant light filling, and can substitute sunlight prolonged exposure 4-10 hour every day fully.Its effect is very apparent, the growth rate of exposure plant is faster intimate 3 times than the plant of general nature growth, solved the frustration that booth lacks sunlight winter, promote needed chlorophyll, anthocyanidin and carrotene in the photosynthesis of plant, making vegetables and fruits do sth. in advance the 20%-50% time gathers, increase by 3 to 5 one-tenth output, more improve the sugariness of vegetables and fruits and reduce disease and pest.
Further, the optically focused LED plant growth lamp of the utility model embodiment can effectively shine by very large-area carrying out to plant, more effectively with light-ray condensing, makes luminous energy change into photosynthetically active radiation.In addition, it have the life-span long, volume is little, in light weight and be characteristics such as solid-state.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
