Abstract: With vigorous promotion of the strategy for rural vitalization，facility agriculture has also ushered in a golden age of rapid development.As an important part of facility agriculture，plant factory plays an important role in modern agricultural engineering.However，due to influence of natural weather，such as overcast rain，haze，rain and snow，greenhouse in traditional plant factories often makes plants lack of light and causes diseases.Because of this problem，a supplementary lighting equipment was developed based on rotary cultivation frame，which aimed to prevent plants on rotary cultivation frame from wilting，yellowing and prolonging growth period caused by uneven light，and also provided theoretical guidance and technical reference for development of same kind of supplementary lighting equipment.
