A kind of plant growth lamp
Technical field
The utility model relates to a kind of plant growth lamp, belongs to the technical field of semiconductor lighting and plant culture apparatus.
Background technology
Only green plants carries out the indispensable energy source of photosynthesis.Only under illumination condition, plant could normal growth, bloom and solid.The photosynthesis of plant refers to that plant absorbs solar energy by chlorophyll, and carbon dioxide and hydration are become organic matter (carbohydrate), and with light energy conversion, is that chemical energy is preserved, and emits simultaneously oxygen.The carbohydrate that photosynthesis generates, be further converted to starch and fat etc., and is required for vital movement.All green plantss must just can carry out photosynthesis in the sun, and the organic substance of photosynthesis synthesized is the material base of plant growth, growth.Light can the stimulating plant tissue and the differentiation of organ, also can restrict the g and D speed of organ simultaneously, can also control cell division, promotes the increase of cell and differentiation etc.So, the growth of plant all with the intensity of illumination close relation.
At present, a lot of lamps that are used for plant growth are arranged on market, but these plant growth lamps efficiency is very low under many circumstances, have that wavelength differs large, power consumption is larger, the life-span is short, light decay is fast, is that on-off times is low.Light a lamp for a long time, on-off times can cause the fluorescent tube premature aging; Stroboscopic is serious, during unlatching, needs flashing of several seconds, after the several months of lighting a lamp, lighting tube brightness there will be obvious decay, and the fluorescent tube quality is also uneven, need to often change, and maintenance cost is high, and ballast and fluorescent tube need to be installed separately, and do not save space, also can not meet the needs of plant growth.
The data record is arranged, and your impact is different to the light of different wave length on photosynthesis of plant, the light that photosynthesis of plant needs, and wavelength is between 400 ~ 700nm; And wavelength at the blue light between 400 ~ 500nm and wavelength the ruddiness between 610 ~ 720nm maximum for photosynthesis contribution.
For this reason, people need to a kind ofly can reduce power consumption, long service life, expense is more saved, and is low in the pollution of the environment, and dissipation of heat is few, green, red, blue three kinds of light can be sent again,, according to the proportioning of the light different proportion red, that blue light is different from white light, demand of plant growth can be more be fit to.
The utility model content
Based on above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of plant growth lamp, the characteristics that this has plant growth lamp to have under long service life, low in energy consumption, low in the pollution of the environment, low pressure just to work, expense is more saved, but also according to red, blue light respectively with white light in proportion the 1:1 proportioning arrange, more be fit to plant growth.
The first technical scheme of the present utility model is: a kind of plant growth lamp, comprise printed circuit board and a plurality of LED lamp pearls that are installed on printed circuit board, described printed circuit board is the linear pattern printed circuit board, it is the white light pearl of 5500 ~ 5800K that described a plurality of LED lamp pearl includes red globe lamp pearl and the colour temperature that wavelength is 440 ~ 655 nm, described red globe lamp pearl is 1:1 with the quantity ratio of white light pearl, and described red globe lamp pearl layout alternate with the white light pearl.
Further, the wavelength of described red globe lamp pearl is 562 nm.
Further, the colour temperature of described white light pearl is 5675K.
Further, a plurality of LED lamp pearls that are installed on printed circuit board are arranged in a row, 80 of total numbers of these LED lamp pearls, and wherein the red globe lamp pearl is 40,40, white light pearl.
The second technical scheme of the present utility model is: a kind of plant growth lamp, comprise printed circuit board and a plurality of LED lamp pearls that are installed on printed circuit board, described printed circuit board is the linear pattern printed circuit board, it is the white light pearl of 5500 ~ 5800K that described a plurality of LED lamp pearl includes blue-ray light pearl and the colour temperature that wavelength is 440 ~ 455 nm, described blue-ray light pearl is 1:1 with the quantity ratio of white light pearl, and described blue-ray light pearl layout alternate with the white light pearl.
Further, the wavelength of described blue-ray light pearl is 447 nm.
Further, the colour temperature of described white light pearl is 5762K.
Further, a plurality of LED lamp pearls that are installed on printed circuit board are arranged in a row, 80 of total numbers of these LED lamp pearls, and wherein the blue-ray light pearl is 40,40, white light pearl.
The beneficial effects of the utility model are: the one, and this plant growth lamp adopts LED lamp pearl to make up the problem that plant growth lamp is overcast and rainy, sunlight is not enough, can make crop yield 20% left and right, canopy chamber.The 2nd, this plant growth lamp adopts LED lamp pearl can not only send the narrower monochromatic light of wave-length coverage, also can be combined into as required shades of colour and colour temperature, and the 3rd, this plant growth lamp can provide rational luminous environment for plant growth.And LED lamp pearl belongs to the cold light source of low heat generation characteristic, under low pressure just can work, can in-plant irradiation plant, and the raising space availability ratio, the saving power consumption, environmental pollution is few, more energy-conserving and environment-protective.The 4th, this plant growth lamp according to red, blue light respectively with white light in proportion the proportioning of 1:1 arrange, can more be fit to demand of plant growth, help to shorten the plant growth cycle, the purpose of raising output, the plant growth of canopy chamber, Production requirement more.
