The growth of everything depends on the sun, and the requirements of plants for light are mainly light color, spectrum, light intensity and light time. Therefore, the artificial development of specific spectrum lighting products can greatly improve plant growth. LED plant lights can be widely used in plant cultivation, but the electricity bill in the production cost of plant factories accounts for about 30%. The development of resource-saving light sources is a necessary requirement for the construction of plant factories.

Sunlight is composed of light waves of many different wavelengths, and only a very small part of the solar radiation spectrum affects photosynthesis, accounting for about 5% of the sun. Through research, the best ratio of 620-680nm red light and 400-500nm blue-violet light was obtained, and the LED plant light was successfully developed.

LED plant lights can not only emit monochromatic light with narrow light waves, such as red, orange, yellow, green, blue, infrared, etc., and can be combined arbitrarily according to different needs of plants, but also a cold light source with low heat generation characteristics and reduce pesticides , Hormones and other chemicals to ensure food safety.
