A LED flexible light chain for facility cultivation

technical field

The utility model belongs to the technical field of artificial light sources for cultivation of plants and edible fungi, in particular to an LED flexible lamp chain for facility cultivation. the

Background technique

Facility horticulture is an important form of modern agriculture. It can carry out intensive cultivation and off-season production of vegetables, flowers, fruit trees and Chinese medicinal materials inside facilities (greenhouses, plant factories, plastic greenhouses, etc.), with high multiple cropping index, high yield and environmental factors. With the advantages of adjustable and annual production, it is the main production method to meet the needs of urban and rural residents for winter and spring vegetables and other horticultural products, and has an irreplaceable role. my country is a big country in the production of protected horticulture, and the cultivated area and output of protected horticulture rank first in the world. However, since the cultivation forms of protected horticulture in my country are mainly solar greenhouses and plastic greenhouses, the light inside the facilities is only about 70% of that outside the facilities. It restricts the growth and development of facility crops and the formation of yield and quality. In my country, continuous cloudy days caused by severe weather such as rain, snow, fog, etc. occur from time to time. Under the simultaneous effect of low temperature, weak light and lack of sunlight often lead to crop production reduction or even failure, and economic benefits cannot be guaranteed. Especially around metropolitan areas, the low transparency of the atmosphere caused by air pollution also exacerbates the occurrence and harm of cloudy days. the

Artificial light supplement is an important technical means to ensure the high quality and high yield of protected gardening under the condition of low light and little light. However, traditional supplementary lights, such as high-pressure sodium lamps, have the defects of high energy consumption, low light efficiency, and a large difference between the spectrum and the photosynthesis requirements of plants, and it is difficult to ensure the efficient production of facility crops. LED is a semiconductor solid-state light source, which has the advantages of small size, light weight, energy saving and environmental protection, long life, and the spectrum can be adjusted according to the needs of plants. It has incomparable photoelectric advantages compared with traditional light sources. ideal light source. More importantly, the LED light source is a cold light source, which can be irradiated close to the surface of plant leaves, reducing the irradiation distance and improving the biological light effect. Therefore, in order to realize the efficient function of the LED supplementary light device, it is necessary to use the adjustment device to achieve real-time close-up supplementary light based on the height of the plant canopy of the facility, and realize the uniform adjustment of the level and height of the real-time LED lamps to achieve energy saving and efficient production. . the

Facility horticultural plant cultivation is mainly carried out in solar greenhouses and glass greenhouses. Traditionally, artificial supplementary light mainly adopts ceiling lighting technology. Due to the low supplementary light intensity of the light source at a long distance, the supplementary light effect on tall plants such as tomatoes and cucumbers is very poor. Effectively carry out the photosynthesis of the lower leaves, which has a great influence on the yield and quality of crops. The LED supplementary light source can irradiate the organisms in the facility at close range, and the lighting efficiency is greatly improved. However, existing LED light sources have some deficiencies and cannot be effectively used under facility conditions. Most of the existing LED supplementary light sources are panel lamps, bulb lamps, lamp tubes and light strips. When panel lamps, bulb lamps and lamp tubes irradiate plants or edible fungi at close range, the irradiation area is small, the price is expensive, and the portability is poor. It is difficult to use it in a large area in the greenhouse due to its shortcomings such as cumbersome disassembly. At the same time, most of the current supplementary light sources are point light sources. Although the light strip is bendable and easy to change the irradiation area, its linear light-emitting mode easily leads to weak luminous intensity. It is suitable for plant lighting or edible fungus lighting that requires high light intensity The above effect is not good. the
