[0002] Plant cell or microalgae culture is an important technology in modern biology and is necessary for studying new plant or microalgae species. For the culture conditions of a plant or microalgae cell, the light factor, including light intensity and light type, is not only directly related to the basic life activities of the plant or microalgae, but also indirectly affects the quality and quantity of the plant or microalgae cell output. In the study of plant or microalgae physiology, light is also an important experimental variable that must be considered.

[0003] At present, the method of controlling light in plant or microalgae cell culture technology usually uses light culture racks or light culture boxes to generally unify the conditions, or generally calculates the light conditions according to the number of lights on. This method has the following problems: 1. Due to the uneven distribution of light sources, it is not accurate enough, and the calculated values ​​cannot reflect the actual experimental conditions well; 2. It is easily affected by the external environment, such as the opening and closing of fluorescent lights in the laboratory outside the culture room; 3. It is not possible to specifically regulate and analyze a single culture bottle; 4. When processing a small number of samples, a lot of energy and resources are required to meet a certain condition, such as requiring multiple light culture boxes; 5. It is impossible to eliminate the mutual influence of different experimental conditions in the same culture room, and there is a great demand for culture space when processing different experiments; In summary, the traditional light culture rack or light culture box is used for the control of light variables when culturing plants or microalgae cells. There are limitations such as being susceptible to interference, large errors, large experimental time and space required, and multiple equipment.

[0004] The Chinese patent with publication number CN205874450U and publication date 2017.01.11 discloses a plant cell or microalgae culture device with controllable light intensity and light species, comprising: a stainless steel culture bottle for culturing plant cells or microalgae; a breathable and light-transmitting cover threadedly matched with the stainless steel culture bottle, the breathable and light-transmitting cover comprising a breathable part and a light-transmitting part; and an electronic light control device disposed on the light-transmitting part of the breathable and light-transmitting cover. The device can only change the light intensity to a certain extent, and is not applicable when some microalgae require strong light. Utility Model Content
