      The artificial climate box is a sealed box equipped with temperature, humidity and light control, which can simulate the natural climate environment in nature to meet the needs of plant growth and development. In the artificial climate box, the main source of light for the plants is the artificial light source. Since the natural climate environment in nature is to be simulated, the first principle to be followed when designing the light source of the artificial climate box is that the spectrum of the light source is similar to The spectrum of sunlight. Another light source design principle is that the light intensity of the light source is greater than the light saturation point required for the growth and development of the cultivated plants.

      The above are the two principles to be followed in the design of the light source of the artificial climate box. Let's talk about the reasons why the design of the light source of the artificial climate box needs to follow these two principles. We know that in nature, it is the sun that provides the light source for plants. Plants can only perform photosynthesis when they receive sunlight. The artificial climate box is used indoors and needs to meet the requirements of precise regulation. Therefore, sunlight is used To carry out research is not shown. At this time, only artificial light sources can be used. In order to ensure the fairness and authenticity of the research results, the closer such light sources are to natural light sources, the more reasonable and effective the test results will be. Therefore, artificial climate The first principle of box light source design is that the spectrum of the light source should be similar to that of sunlight.

      Secondly, the light required for the growth and development of cultivated plants generally has a saturation point. If the range of light regulation in the artificial climate box is not wide enough, then for some plants with high light requirements Therefore, in the design of the light source of the artificial climate box, it is also necessary to ensure that the light intensity of the light source is greater than the light saturation point required for the growth and development of the cultivated plants. All kinds of plant species can be used for research work using artificial climate chambers.
