Biological optimization systems for enhancing photosynthetic efficiency and methods of use

1. A method for enhancing photosynthetic efficiency comprising:

applying pulsed light to a photosynthetic organism;

using a chlorophyll fluorescence feedback control system to determine one or more photosynthetic efficiency parameters, wherein the photosynthetic efficiency parameters are used to adjust one or more of the following: a pulse rate, pulse on/off duration, light intensity, light spectrum, or a combination thereof;

adjusting one or more of the photosynthetic efficiency parameters to drive a photosynthesis by delivering of an amount of light to optimize light absorption of the photosynthetic organism while providing enough dark time between light pulses to prevent oversaturation of a chlorophyll reaction center; and

changing the light intensity of a spectral composition of pulsed light by decreasing an intensity of wavelengths that are strongly absorbed and increasing an intensity of wavelengths that are weakly absorbed to allow deeper penetration of light energy into a culture or canopy of the photosynthetic organism.

2. The method of claim 1 , wherein the chlorophyll fluorescence feedback control system includes the photosynthetic organism, a fluorometer, and a LED illuminating system.

3. The method of claim 1 , wherein the pulsed light is derived from a source that comprises one or more of: a light-emitting diode (LED), organic light-emitting diode (OLED), or a combination thereof.

4. The method of claim 1 , wherein the pulse rate is between about 500 Hz to 10 kHz.

5. The method of claim 1 , wherein a wavelength of the pulsed light is selected from the group consisting of: blue LED (440-490 nm), cyan LED (505 nm), white LED (2700 k-10,000 k), and a combination thereof.

6. The method of claim 1 , wherein the pulsed light applies blue (440-490 nm) and red (600-680 nm) light to the culture or canopy and the culture or canopy has strong absorption in the blue (440-490 nm) and red (600-680 nm) regions.

7. The method of claim 6 , wherein the culture increases its density during cultivation, preventing effective light penetration into the culture or canopy and inducing increased energy dissipation as heat (NPQ), and further comprising:

decreasing an intensity of blue and red illumination; and

changing an intensity of illumination to colors having higher reflections than the blue and red illumination, wherein the colors having higher reflections are selected from the group consisting of: cyan (495-515 nm), green (520-540 nm), orange/amber (565-595 nm), and a combination thereof.

8. A method for enhancing photosynthetic efficiency comprising:

applying pulsed light to a photosynthetic organism, wherein the pulsed light applies blue (440-490 nm) and red (600-680 nm) light to a culture or canopy of the photosynthetic organism and the culture or canopy has strong absorption in blue (440-490 nm) and red (600-680 nm) regions;

using a chlorophyll fluorescence feedback control system to determine one or more photosynthetic efficiency parameters, wherein the photosynthetic efficiency parameters are used to adjust one or more of the following: a pulse rate, pulse on/off duration, light intensity, light spectrum, or a combination thereof; and

adjusting one or more of the photosynthetic efficiency parameters to drive photosynthesis by delivering of an amount of light to optimize light absorption of the photosynthetic organism while providing enough dark time between light pulses to prevent oversaturation of a chlorophyll reaction center,

wherein the culture or canopy increases its density during cultivation, preventing effective light penetration into the culture or canopy and inducing increased energy dissipation as heat (NPQ), and further comprising:

decreasing an intensity of blue and red illumination; and

changing an intensity of illumination to colors having higher reflections than the blue and red illumination, wherein the colors having higher reflections are selected from the group consisting of: cyan (495-515 nm), green (520-540 nm), orange/amber (565-595 nm), and a combination thereof.

9. The method of claim 8 , wherein the chlorophyll fluorescence feedback control system includes the photosynthetic organism, a fluorometer, and a LED illuminating system.

10. The method of claim 8 , wherein the pulsed light is derived from a source that comprises one or more of: a light-emitting diode (LED), an organic light-emitting diode (OLED), or a combination thereof.

11. The method of claim 8 , wherein the pulse rate is between about 500 Hz to 10 kHz.
