Problems solved by technology

[0002] The light-emitting diode with special spectrum is to simulate the spectrum of natural light, which contains the spectrum required for plant growth. Its characteristics have been studied and proved that under different light intensity, spectrum and photoperiod conditions, there are different requirements for the growth of plants. And conditions, and the most important photosynthesis has a great impact on green plants. The efficiency of light sources on plant photosynthesis has been studied by American and Japanese scholars. It is the most suitable for the spectrum. The more suitable the light source for plant growth is in line with its most suitable spectrum. , the greater the benefit to plant photosynthesis, and the correct spectrum will also accelerate biological growth, and the biological growth spectrum also needs to be specially adjusted. At present, the special spectrum is mainly used in the field of LED lighting, and the application range is narrow. For biological growth and plant There is no relevant technology in the field of irradiated growth
