Abstract
Description
Technical field
[0001] The present invention relates to a lighting device with mixed light sources, in particular to a plant cultivation device designed to adapt to different lighting requirements of different plants by using different lighting modules and a preset waveform database. 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 bottle under the light, and other measures must be taken to improve it. Otherwise, it may damage the growth of the cultivated seedlings. Therefore, there have been recent studies on the use of light emitting diodes (LEDs) to cultivate tissue cultured seedlings. The light-emitting diode is a cold light source, which can be very close to plants during cultivation to increase the utilization rat...
