Abstract

The invention discloses a special spectrum simulation illumination device for plant cultivation and a simulation method. In the invention, the design idea of single light source is broken through; a hexagonal extensible light source array is designed based on LED combination; control power supply is realized by signal chip computer control and inductance switch stabilized current; the configuration parameter of a light source is determined by a monochrome calibration method; and the simulation of a special spectrum is realized by a nonlinear least squares curve fitting. The device has the advantages of special spectrum simulation, light-reliable-efficient performances, convenient extension and strong commonality. The simulation test result shows that the invention can pointedly and flexibly simulate the visible light absorption spectrum of special plants, solves the technical problem that how to supply light efficiently and flexibly for biological culture and provides a new technical solution for biological scientific study, biological culture and fresh-keeping in special environment and the like.

Description

technical field [0001] The present invention relates to the field of lighting source technology and photoecology research, and specifically refers to a specific spectrum simulation lighting device and simulation method for plant cultivation, which is widely used in laboratory plant cultivation research and plant cultivation and preservation in special environments such as space and underground And many other aspects. Background technique [0002] Sunlight provides sufficient energy for plants on the earth and meets the growth needs of thousands of plants. Photosynthesis is the basis for the growth of most plants. Not only growing plants need photosynthesis, but even picked vegetables and fruits are still alive and will also undergo photosynthesis. Good and appropriate light will promote the life metabolism of plants , Increase the nutrition of vegetables and fruits. Not only does light control plant photosynthesis as an energy source, but it also acts as a trigger that aff...
