Description

Technical Field

[0001] The invention relates to the field of light environment control, and more specifically to a plant light environment regulating light panel. Background Art

[0002] Light is the original driving force for plant growth and development, and is related to physiological metabolic processes such as photosynthesis, photomorphogenesis, material metabolism, and mineral and water absorption. Different light environments (light quality, light intensity, and photoperiod) have an important impact on plant growth and development. Different types of plants or the same type of plants at different growth stages require different light environments. In artificial plant cultivation and plant growth experiments, it is necessary to be able to effectively simulate the light source required for plant growth and development to fit the real growth environment of the plants and promote plant growth. However, the regulation of plant light environment is still in the exploratory stage.

[0003] With the rapid development of LED industry technology, the rise of artificial light source LED, especially the increasingly mature high-power LED preparation technology, has provided a necessary foundation for the study of plant light environment. LED has many unique advantages that other light sources cannot compare with, such as high photoelectric conversion efficiency, energy saving and environmental protection, use of direct current, small size, low energy consumption, and fixed wavelength.

[0004] However, most of the LED light sources currently used in plant light environments are monochromatic or a combination of two or three colors. Common ones include red, blue, green, ultraviolet and infrared monochromatic light sources, as well as red and blue combinations, red and white, blue and white, and red, blue and green combinations of LED light sources in different proportions. Although these light sources can also achieve certain spectrum adjustment, the same system or device cannot simultaneously achieve the control of the spectrum segment, the radiation intensity of each segment, and the radiation time, and cannot meet the simulation of the light environment required for plant growth and development. Moreover, in order to set different plant light environments in terms of spectral composition and radiation intensity, many different light sources need to be configured, which requires a lot of manpower and material resources, has poor versatility, and has a very low utilization rate, resulting in a waste of resources. Summary of the invention
