Description

2000K color temperature spectrum LED lamp for plant illumination
Technical Field
The invention relates to a 2000K color temperature spectrum LED lamp for plant illumination, and belongs to the technical field of plant illumination light sources.
Background
Plant lighting is rapidly developed in recent years, and has become an important hotspot field for cross-border fusion of lighting and agriculture. The luminous environment is one of the most important environmental factors required by plant growth, the natural climate change is uncertain, and under the influence of weather such as rainy days, cloudy days and the like, the situation of insufficient natural illumination is easy to occur, so that the plant growth is influenced. Moreover, the temperature and humidity change and the influence of plant diseases and insect pests are difficult to avoid when the plants are planted in exposed days, the evaporation speed of the substrate moisture is high, the quality and the yield of crops are influenced by factors such as uneven fertilization, and the output is unstable; the plant morphogenesis is an important technology in the field of facility cultivation through controlled light quality regulation and plant morphogenesis control, namely, sunlight irradiation is replaced by artificial light, unstable climate factors of nature are replaced by computer intelligent regulation and control environment conditions, and the like, and indoor intelligent agriculture and artificial light cultivation are finally the development trend of future agriculture.
The traditional plant growth is more common and mature, and the adopted plant illumination light source is a sodium lamp. Sodium lamps, particularly high pressure sodium lamps, are electrical light sources that utilize sodium vapor to be ionized and discharged to produce visible light. When the sodium lamp bulb is started, an electric arc is generated between electrodes of an electric arc tube of the sodium lamp, sodium and mercury in the electric arc tube are heated and evaporated into mercury vapor and sodium vapor under the action of high temperature, electrons emitted in the electric arc tube impact the sodium vapor in the process of moving to the anode, and light is generated through ionization discharge. The sodium lamp plant has complete illumination color temperature spectrum, can meet the requirements of plant growth, flowering, fruiting and the like, for example, the wavelength is 400-430 nm, and helps the plant to form anthocyanin and resist the growth of branches and leaves; the wavelength is 550nm, so that the growth of oxygen is promoted, and tissues are helped to better accumulate nutrients; the wavelength is 580nm, and the growth of roots and the initial germination stage can be promoted; the wavelength is 650-660 nm, the growth of the whole plant is promoted, particularly in the flowering period and fruiting period, the growth speed is increased, the number of fruits is also increased, the incidence rate of malformed fruits is reduced, and the like. However, sodium lamps also have disadvantages for plant lighting. Sodium lamp plant illumination energy consumption is too high, and luminous efficacy is too low, more fragile, the cost is higher, and mostly single light source adds simple static control system mode, and inconvenient closely shine for a long time to the plant, is difficult to satisfy the light quality demand that plant growth develops at different time, different stages change etc..
LED lamps are increasingly used as new plant lighting sources. Compared with the traditional light source, the LED lamp light source has the advantages of high electro-optic conversion efficiency, adjustable light intensity spectrum, long service life, intelligent control and the like, is a low-heating cold light source, can irradiate plants in a short distance without causing burn, is small in size, is suitable for a multilayer three-dimensional combined cultivation system, contributes to reducing the layer height of a cultivation layer frame, increases the cultivation density advantage of a unit space and the like, is an ideal light source for modern facility agriculture plant illumination, and has a good application prospect in the fields of agriculture and biology. Under the influence of external factors such as insufficient cultivated land in China, the LED lamp plant illumination can be developed vigorously, and more and better guarantees are provided for food safety in China.
At present, LED plant illumination starts late in China, but the development is rapid and the potential is huge. As a new market, plant lighting is low in permeability in China, and in recent years, people pay more and more attention to the field of agricultural innovation such as plant factories and greenhouses for light supplement. Various light source schemes are different at present according to the differentiated requirements of plant growth. How to obtain a more ideal plant lighting LED lamp scheme is a research hotspot of the industry, and has the advantages of fierce competition, huge market prospect and huge development potential.
