Flashing lights are next-generation tools to mitigate light attenuation and increase the photosynthetic efficiency of microalgal cultivation systems illuminated by light-emitting diodes (LEDs). Optimal flashing light conditions depend on the reaction kinetics and properties of the linear electron transfer chain, energy dissipation, and storage mechanisms of a phototroph. In particular, extremely short and intense light flashes potentially mitigate light attenuation in photobioreactors without impairing photosynthesis. Intelligently controlling flashing light units and selecting electronic components can maximize light emission and energy efficiency. We discuss the biological, physical, and technical properties of flashing lights for algal production. We combine recent findings about photosynthetic pathways, self-shading in photobioreactors, and developments in solid-state technology towards the biotechnological application of LEDs to microalgal production.
闪光是一种下一代工具，可以减轻光衰减并提高发光二极管 (LED) 照明的微藻培养系统的光合效率。最佳闪光条件取决于光养生物的线性电子转移链的反应动力学和特性、能量耗散和储存机制。特别是，极短而强烈的光闪光有可能减轻光生物反应器中的光衰减，而不会损害光合作用。智能控制闪光单元和选择电子元件可以最大限度地提高发光和能源效率。我们讨论了闪光在藻类生产中的生物、物理和技术特性。我们结合了关于光合途径、光生物反应器中的自遮蔽以及固态技术发展的最新发现，将 LED 应用于微藻生产的生物技术。
