WIPO Patent Application WO/2023/046123

A1

A multi-section periodic light emitting apparatus for agricultural lighting, and a lighting method. The light emitting apparatus comprises a lighting device (21) comprising a first lighting portion (21a) having an arc-shaped irradiating surface and a second lighting portion (21b) having an annular irradiating surface which are arranged on a shaft body (101) of a cultivating device (1); the first lighting portion (21a) and the second lighting portion (21b) are capable of providing controllable light having variable intensity/brightness on the basis of the input of an adjustable pulse voltage, and the pulse period of the pulse voltage comprises a first wave band and a second wave band; the first lighting portion (21a) and/or the second lighting portion (21b) are capable of providing controllable light by adjusting the corresponding light emitting duration, light emitting intensity and/or light source ratio on the basis of the voltage and/or current change(s) of the first wave band; and the first lighting portion (21a) and/or the second lighting portion (21b) are capable of generating controllable light having light emitting intensity/brightness approaching or equal to zero candela on the basis of the voltage-free state of the second wave band.
