[0002] When doing photosynthesis experiments on plants in the summer, the sun often shines directly on the photosynthesis instrument (such as the LI-6400 model). First, the temperature of the instrument will be too high, which may cause instrument failure or power consumption. Second, direct light will cause the instrument panel to reflect, affecting the efficiency of the experimenter in observing data or recording data. Third, it can help the experimenter to protect against the sun. Existing sun protection methods usually add additional experimenters to manually hold umbrellas to block the sun. A few have different shielding devices but cannot be fixed, and cannot adjust the direction according to the changes in the sun's altitude angle throughout the day, and the shielding effect is poor. Utility Model Content
