Description

LED plant lamp capable of adjusting illumination space distribution and light quality conditions

Technical Field

The utility model relates to a plant lamp technical field, in particular to LED plant lamp of adjustable illumination spatial distribution and light quality condition.

Background

The plant growth lighting system is an important unit in indoor planting of intelligent greenhouses, plant factories and the like, illumination plays a key role in plant photomorphogenesis, plastid differentiation and plant growth and development, and not only is the driving force of plant photosynthesis, but also is a plant growth regulation and control signal, and the growth and development process of plants is regulated by exciting related gene expression to influence the yield and quality of the plants. A series of photoreceptors exist in the plant body, so that the plant can accurately and timely sense the change of the light environment. The existing research shows that the light environment (illumination intensity, light quality proportion, illumination period, illumination time and space distribution) for plant growth is comprehensively and finely regulated, and a reasonable illumination regulation scheme and light distribution are formulated, so that the plant quality can be remarkably improved, and the energy consumption of a light source can be effectively reduced.

The LED illuminating lamp is widely applied to the fields of outdoor street lamps, architectural illumination and indoor daily illumination. The LED light source not only fully utilizes the advantages of pure light quality, energy conservation, durability, spectrum regulation, cold light source, safety, environmental protection and the like of the LED, but also can achieve the aim of high-efficiency application as a special light source for facility horticulture. When the LED light source is applied to plant illumination, the light source performance and the applicability of facility gardening production should be improved in design, and the advantage of high degree of freedom of the LED light source is fully exerted. In the aspect of the LED plant lamp body, the light quality and the light intensity can be adjusted, so that the LED plant lamp has multiple purposes and broad-spectrum applicability. On the mode of hanging and shining of LED plant lamp, the demand that can satisfy different kind plant cultivation platforms lets the plant leaf obtain the vertical illumination of short distance transmission to the at utmost.

The design principle of the LED plant light supplement lamp device comprises: according to the principle of closing, the light source position should be close to the canopy blade as much as possible on the basis of ensuring a certain effective irradiation area through mechanical suspension or fixation, and the light attenuation caused by the fact that the distance is increased is reduced. According to the principle of irradiation area, the LED light source has a certain effective canopy irradiation area, and the excessively high or low irradiation area affects the light intensity and the light supplement effect. The principle of vertical blades aims at different plants of leaf vegetables, fruits and vegetables and vertical blade types, the illumination is perpendicular to the blades as much as possible, the light supplementing photosynthetic efficiency is improved, and the yield is increased. According to the dynamic principle, the light-quality conditions such as light-quality ratio, light period, illumination intensity and the like can be dynamically adjusted in different growth stages according to plant species.

In terms of light quality conditions: plant photosynthesis efficiency, yield and quality are closely related to light conditions, which are the least easily regulated environmental factors in plant growth. When plants are subjected to photosynthesis, the areas with the strongest chlorophyll absorption spectra are in a red light wave band with the wavelength of 600-700 nm and a blue light wave band with the wavelength of 420-470 nm, namely, the plant photosynthesis has the highest light quantum efficiency in the blue light and the red light wave bands. Besides influencing the photosynthesis rate, different lights such as white light, red light, yellow light, blue light, green light and the like have different regulation and control effects on the growth and development of plants, influence on the formation of plant leaf green bodies, the synthesis of photosynthetic pigments, the movement of leaf pores, the extension of leaves, carbon assimilation and rhizome growth of plants, influence on the biosynthesis of soluble proteins and saccharides, and regulate and control the synthesis of secondary metabolites such as plant physiology and biochemistry, carbohydrate metabolism, protein generation, total phenols, anthocyanin and ascorbic acid. The light quality of the light source applied to the plant light supplement lamp at present mainly combines the 660nm red light and 460nm blue light monochromatic LED chips, and a plurality of single-chip LEDs are alternately arranged to form a lamp tube or a lamp panel, and a small amount of ultraviolet light and far-red light can be added into the newly developed LED light source. The LED fluorescent plant growth lamp converts part of blue-violet light into red light or other light by coating the modulated fluorescent powder on the surface of a blue-violet LED chip with low wavelength. The LED plant lamp adopts the combination of the fixed lamp beads, so that the light quality is not easy to adjust, and the problem of light spots is easy to generate on the irradiation surface.

In terms of light source spatial management: the high energy consumption of the lighting system is one of the main factors for restricting the large-scale popularization of the LED plant light supplementing device. The spatial distribution of the LED light sources is adjusted, and the energy consumption can be reduced under the condition of high-efficiency cultivation. The luminous angle of LED lamp pearl is generally at 120~140 degrees, and too close to the plant makes the canopy blade be in the light inhibition state always easily, and keeps away from the plant, increases invalid irradiation area easily, reduces the electric energy utilization efficiency of light source. The canopy structure of the plant also causes the space of the illumination condition to be uneven, and the leaves in the canopy and the middle and lower parts are in the state of insufficient illumination for a long time, thus influencing the yield and the quality of the plant. The height, the irradiation angle and the light-emitting angle of the light source are adjusted, the using amount of the LED light source can be reduced, the invalid illumination area is reduced, and the electric energy utilization rate is improved.
