Problems solved by technology

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

Description

Technical field [0001] The invention relates to the technical field of light source deployment, in particular to a light-emitting diode with a special spectrum and its application. Background technique [0002] A light-emitting diode with a special spectrum. It simulates the spectrum of natural light. It contains the spectrum required for plant growth. The study of its characteristics has proved that under different light intensity, spectrum and photoperiod conditions, it has different effects on plant growth. Among them, photosynthesis, the most important of which, has a huge impact on green plants. The efficiency of light sources on photosynthesis of plants 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 Spectral diagram, the greater the benefits of plant photosynthesis, in addition, the correct spectrum will also accelerate biological growth, the biological growth spectrum also re...
