Study on Lighting Technology of Plant Factory Based on Plant Light-harvesting Pigment

In order to overcome the shortcomings of traditional light distribution in plant factories, such as low accuracy and high energy consumption, this paper starts from the principle of plant light harvesting and proposes a light distribution method based on plant pigments, which can solve the needs of different plants in different periods of light source spectrum. This article mainly introduces the light distribution theory based on plant pigments, and uses this theory to simulate the light distribution of lettuce. Due to the wide spectrum of the existing LED light source, there is an error of about 20% between the emission spectrum of the light source and the absorption spectrum of the lettuce. This method can also provide a theoretical basis for future full-spectrum laser plant lighting.
