In traditional agricultural production, ordinary electric light sources are generally used to supplement the light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, and changing the light environment to regulate the growth and development of plants in the facility cultivation environment. However, these measures have problems of varying degrees, such as lack of analysis of specific spectral components, resulting in impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of plants, and low energy efficiency of the illuminating light source. A large number of application research results of LED plant lights in plant facility cultivation environments show that LED plant lights can solve these problems and are particularly suitable for artificial light-controlled plant facility cultivation environments.
LED plant lights are attracting the attention of the world with their inherent advantages. Especially in the context of rising global energy shortage concerns, LED plant light sources have the characteristics of high luminous efficiency, long service life, safety and reliability, environmental protection and energy saving, so that the prospects of LED plant lights in the lighting market have attracted global attention. .

Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Controlling plant morphology through light quality regulation is an important technology in the field of facility cultivation.
As a fourth-generation new type of lighting source, LED plant lights have many characteristics that are different from other electric light sources, which also makes them the first choice for energy-saving and environmentally-friendly light sources. The LED plant lights used in the field of plant cultivation also exhibit the following characteristics: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; the spectrum wave width is narrow half-width, and pure monochromatic light and compound spectrum can be combined as needed; Concentrate light of specific wavelength to irradiate crops in a balanced manner; not only can adjust the flowering and fruiting of crops, but also control plant height and plant nutrients; the system generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat The load and production space are miniaturized; in addition, its exceptional durability also reduces operating costs. Because of these remarkable features, LED plant lights are very suitable for plant cultivation in a controllable facility environment, such as plant tissue culture, facility gardening and factory seedlings, and aerospace ecological life support systems.
