Light source irradiation device for plant cultivation

Abstract

The invention discloses a light source irradiation device for plant cultivation, comprising a doughnut shape-like LED assembled light source and an octagonal irradiation zone arranged under the doughnut shape-like LED assembled light source. The doughnut shape-like LED assembled light source comprises a light source panel, multiple layers of square LED light rings are arranged on the light source panel, and each layer of square LED light ring is composed of four LED light bars. The multiple layers of square LED light rings are connected with a drive circuit, and the boundary of the octagonal irradiation zone is located within the boundary of the vertical projection zone of the LED light bars in the outermost layer. The luminescent spectrum of the light source irradiation device can well meet the spectral range needed by the plants for growth, and the illumination intensity is stronger than that of the light sources generally used in greenhouses and is completely up to the illumination intensity required by indeterminate plants for growth. At the same time, by adopting the edge supplementary lighting intense design and inner layer uniform design, the light source irradiation device can well improve the illumination uniformity on the premise of ensuring the illumination intensity of the light source, and thus can be applied to the scientific experiments and production practices of plant illumination.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a light source irradiation device for plant cultivation. Background technique [0002] Light is one of the necessary environmental factors in the process of plant growth. Light not only provides energy for photosynthesis of plants, but also regulates various aspects of plant growth, development, morphological structure building and material metabolism. Therefore, accurately grasping the light information of plants is the premise of studying the influence of light on various aspects of plants, and it is also the guarantee for studying the influence of other ecological factors on various aspects of plants. [0003] Due to the characteristics of heat preservation and temperature control, the greenhouse breaks the seasonality of plant growth and overcomes the constraints of low temperature and other climatic conditions on crop production. In terms of scientific research...
