Description

Plant illumination full-spectrum LED lamp

Technical Field

The invention relates to a plant illumination full-spectrum LED lamp, 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 light 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, continuous cloudy days and the like, the situation of insufficient natural illumination is easy to occur, so that the plant growth is influenced. Moreover, outdoor open planting is difficult to avoid temperature and humidity changes and pest and disease damage effects, the substrate moisture evaporation speed is high, factors such as uneven fertilization can affect the quality and yield of crops, and output is unstable; the regulation of controlled light quality and the establishment of controlled plant morphology are important technologies in the field of facility cultivation, namely, artificial light is used for replacing sunlight irradiation, and the unstable climate factors of the nature are replaced by computer intelligent regulation and control environmental conditions, so that indoor intelligent agriculture and artificial light cultivation are 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. The sodium lamp plant has complete lighting spectrum and can meet the requirements of plant growth, flowering, fruiting and the like. However, sodium lamp plant lighting energy consumption is too high, luminous efficiency is too low, it is fragile, cost is higher, and mostly be single light source plus simple static control system mode, inconvenient closely shine for a long time to the plant, be difficult to satisfy the light quality demand that plant growth and development changed at different time, different stages etc..

LED lamps (having a certain wavelength band) are increasingly used as new plant lighting sources. Compared with the traditional sodium lamp light source, the LED lamp light source has the advantages of high electro-optic conversion efficiency, adjustable light intensity, long service life, intelligent control and the like, and is a low-heating cold light source which can irradiate plants in a short distance without causing burn; the volume is small, the cultivation system is more suitable for a multilayer three-dimensional combined cultivation system, the reduction of the layer height of a cultivation layer frame is facilitated, the cultivation density advantage in unit space is increased, and the like; the LED lamp is an ideal light source for plant illumination in modern facility agriculture, and has 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.

The color temperature of sunlight changes along with the change of four seasons and the change of time in the morning and evening, and the sunlight is considered to be more in line with the natural growth rule of organisms. Sunlight is a polychromatic light, which is the spectrum of sunlight by the arrangement of different wavelengths, which can be referred to (considered) as the full spectrum. Full spectrum generally refers to a spectral curve that includes ultraviolet light, visible light, infrared light, and the like. The full spectrum LED lamp aims to simulate the sun (via the LED lamp) to obtain a relatively full spectrum. In artificial light sources, people simulate natural light environment (i.e. the sun "), and hope to obtain a full spectrum light source, and think (intention) (" talent ") more accords with the natural growth rule of organisms. In addition, more realistic, plants have multiple varieties, the same variety and different growth periods, namely, the requirements on illumination are different, and the conventional sodium lamp (mainly a high-pressure sodium lamp) for plant illumination or the conventional LED lamp with single wavelength is always deficient in plant illumination or inconvenient to use. Full spectrum development of LED light sources has continued internationally for many years. However, because the ultraviolet and infrared light parts are difficult to achieve continuous spectrums, i.e., the spectrums of the ultraviolet and infrared light LED lamp beads are narrow and usually limited to a specific waveband, the combination of the ultraviolet and infrared light LED lamp beads into a continuous spectrum has great difficulty and high cost. (it is difficult to simulate sunlight.) this is also a technical problem that people have eagerly solved but have not succeeded all the time.

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.
