PHOTONIC ENGINE SYSTEM FOR ACTUATING THE PHOTOSYNTHETIC ELECTRON TRANSPORT CHAIN
FIG7 is a graph showing the waveforms for the voltage and input currents for the circuit of FIG6
Therefore, current inputted to the first and second lighting elements 32a and 32b is conditioned as shown in FIG7. FIG7 shows the voltage input 80 and current inputs 82 and 84 to lighting elements 32a and 32b resulting from circuit 68. The first current input 82 provides a maximum current input 86 when positive voltage is applied to the circuit and no current 88 when voltage input 80 drops below zero (0). Meanwhile, the second current input 84 provides a maximum current input 90 when voltage is negative, or below zero, while no current 92 is presented when the voltage is above zero or positive.

['1. A horticulture system for growing plants under artificial lighting in an environment, the system comprising: at least one lighting device, the at least one lighting device having a first lighting element (32a) configured to emit light at a wavelength that is within 20 nanometers of a peak absorption of a pigment of a plant (14) positioned in spaced relation to the at least one lighting device to receive light emitted by the at least one lighting device, characterized in that the horticultural system is configured such that light from the first lighting element is pulsed with emission during first, second and third lighting intervals with a first dark interval provided between the first and second lighting intervals and a second dark interval provided between the second and third lighting intervals; and the horticulture system further comprises at least one further lighting element configured to emit a background light with an intensity lower than an intensity of the light emitted by the first lighting element during the first, second and third lighting interval.']
