Problems solved by technology

[0003] It's just that the predecessors used small-scale experiments to study the feasibility of light-emitting diodes as plant cultivation, but they did not specifically design plant cultivation devices based on mass production.
In addition, the plant growth chambers in general laboratories are limited to light sources of several specific wavelengths, and there is no modular lighting design for various plants. Therefore, when changing the lighting method of the experiment, it is often necessary to rely on electronic circuits. Only professional and technical personnel can modify the growth box, so it is not very convenient to use

Description

technical field [0001] The invention relates to a lighting device with a mixed light source, in particular to a plant cultivation device designed to meet different lighting requirements of different plants by using different lighting modules and preset waveform databases. Background technique [0002] In the past, when cultivating tissue culture seedlings in the tissue culture room, fluorescent tubes (tube fluorescent lamps) were often used as artificial light sources. However, fluorescent tubes are heat-generating light sources, which will cause overheating in the tissue culture bottles under the light. Additional measures must be taken to improve this. Otherwise, it may damage the growth of the cultured seedlings. Therefore, recently, people have been studying the use of light emitting diodes (light emitting diodes, LEDs) to cultivate tissue cultured seedlings. The light emitting diode is a cold light source, which can be very close to the plants during cultivation to impr...
