Suspended LED supplementary light device for solar greenhouse and solar greenhouse

technical field

The utility model belongs to the technical field of facility agricultural engineering, and in particular relates to a hanging LED supplementary light device for a solar greenhouse and a solar greenhouse.

Background technique

Facility horticulture is an important form of modern agriculture. Intensive cultivation of vegetables, flowers, fruit trees and Chinese medicinal materials can be carried out in facilities (greenhouses, plant factories, plastic greenhouses, etc.) and off-season production. It has 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. The area and output of protected horticulture rank first in the world, with a facility area of more than 4 million hectares, of which soil cultivation is the main method, accounting for more than 99%, while soilless cultivation only accounts for a very small proportion.

So far, the cultivation form of protected horticulture in my country is dominated by solar greenhouses. Due to the shielding of truss structures and thermal insulation films, the light inside the facilities is only about 70% of that outside the facilities. Insufficient, low light and low light adversity occur from time to time, which seriously restricts the growth and development of my country's facility crops and the formation of yield and quality. In my country's three northern regions and southwestern regions, continuous cloudy days caused by severe weather such as rain, snow, fog, etc. occur from time to time. 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.

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 defects such as high energy consumption, low light efficiency, and uncontrollable spectrum, which makes it 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. However, the current cost of LED lights is high, the irradiation area is small, and the investment in high-density layout is high, which cannot be afforded by vegetable farmers; moreover, the unique structure of the solar greenhouse makes it difficult to hang LED lights in the solar greenhouse, and it is impossible to operate without disturbing the daily operation of the solar greenhouse. Implement effective supplementary light; finally, the light source design is single, and it is difficult to make the canopy of the solar greenhouse flora evenly illuminated.

detailed description

Below by specific embodiment and accompanying drawing, the utility model is described further.

Fig. 1 is an overall schematic view of a solar greenhouse installed with an LED supplementary light device (or LED supplementary light) of the present invention. As shown in this figure, the LED supplementary light device 1 is suspended and installed on the top of the back wall (north wall) or the top of the back slope of the solar greenhouse 2. In the figure, 1a, 1b, and 1c are possible installation positions (installed in only one position) A LED fill light device is enough). The LED supplementary light device fixes the lamp through the damping hinge (the damping hinge is not shown in the figure), and the installation horizontal angle (the angle between the light-emitting surface and the vertical surface) of the lamp can be adjusted so that the illuminated surface covers the canopy area of the greenhouse flora .

FIG. 2 is a schematic diagram of the LED supplementary light device 1 . The LED lamp has a rectangular light-emitting surface and is installed in an east-west direction. The LED light source is composed of high-power or medium-power LED lamp beads 3 arranged in an array, and the red LED and blue LED lamp beads are arranged alternately, and the quantity ratio is 4:1. The LED lamp beads 3 are designed on an aluminum substrate 4, and the number of rows is more than 3 rows. The characteristic is that starting from one side, the density of each row of lamp beads gradually increases, and at the same time, the row spacing of each row of lamp beads gradually decreases to increase the light intensity. level to improve lighting effects. As shown in Figure 2, starting from one end 4a of the aluminum substrate 4 to the other end 4b, the density of each row of lamp beads gradually increases, and the row spacing of the lamp beads gradually decreases. When placed on the top of the back wall or the top of the back slope of the solar greenhouse, the density The end with low row spacing is on the bottom (close to the north wall of the greenhouse), and the end with high density and small row spacing is on the top, so as to facilitate the illumination of the south plant canopy in the greenhouse, so that the intensity of light on the south side is higher, mainly for the greenhouse. Low plants in the south (especially fruit trees) provide suitable light to overcome the difference caused by distance.

The utility model can also set a lampshade outside the LED lamp, so that the beam of light projected by the LED is rectangular, and the projection on the ground just covers the cultivation area of 5-10 meters horizontally on the ground of the solar greenhouse, and the light intensity is consistent. Figure 3 and Figure 4 are schematic diagrams of the irradiation range of LED lights. In Figure 3, the area between a and b is the irradiation area. As the growth height of the plant increases, the canopy level increases. See plant 5 in Figure 4, and the light is emitted by adjusting the light downward. The angle between the surface and the vertical surface is used to adjust the scope of the irradiated area of the lamps and reduce the irradiated area to the south of the solar greenhouse.

As mentioned above, the hanging type LED supplementary light device for solar greenhouses of the present invention can not only cover the main cultivation areas of solar greenhouses, but also save the amount of LED lights and reduce input costs through specific installation positions, installation angles and adjustment methods. A better input-output benefit is obtained; at the same time, the light quality and intensity of the supplementary light of the canopy of the solar greenhouse flora are uniform, and the light cycle is prolonged.
