Problems solved by technology

Moreover, this patent does not conduct further research on the relationship between light intensity, spectrum, luminous duration and plant growth in the bright cycle and dark cycle, nor does it form the luminous curve changes in the bright cycle and dark cycle
Therefore, the patent cannot accurately match the light-dark cycle with the photosynthesis of plants

Abstract

The invention relates to a stroboscopic method for a plant lighting device. The method comprises the following steps: establishing connection between a lighting assembly network of a driving circuit and a group of input terminals used for receiving constant electricity in order to receive periodic pulse voltage, adjusting inputted pulse voltage by the driving circuit and dividing one pulse periodinto at least two phases, wherein at least one phase is a voltage-changing phase of voltage value from changes in set value to zero-volt voltage, and the other phase is a no-voltage phase; respondingto voltage in the voltage-changing phase and / or adjusting lighting duration, lighting intensity, light spectrums and / or change rules of lighting curves along with current changes by a lighting assembly in order to emit controllable light; responding to the no-voltage state in the no-voltage phase by the lighting assembly in order to generate controllable light with lighting intensity / luminance close to or equal to zero candela; and selecting corresponding lighting control schemes according to plant position parameters, growth phase features and / growth element features such that periodic lightchanges of the lighting assembly match plant growth demands.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to a stroboscopic method for an illumination device. Background technique [0002] The growth of each vegetation requires light, but the wavelength of light required by each vegetation during each growth period, as well as the irradiation time and intensity of light are different. A large number of studies and applications of plant growth lights in facility cultivation environments have shown that it can solve the problems of impure light quality, inconsistent light intensity, and low energy efficiency of light sources in the spectral components of other artificial light sources. The light supplement technology of plant growth lamp can significantly promote the development of spinach, radish and lettuce, improve the morphological indicators, and increase the growth rate and photosynthetic rate by more than 20%. Enables maximum betalain bioaccumulation in sugar beets and produc...
