Popis: The production of microglons for energy purposes is difficult and costly. One of the important parameters influencing the efficiency of photosynthesis in photobioreactors is light radiation. In order to obtain information on the distribution of intensity of photosynthetic active radiation PAR in the PBR space measurements of the photon flux (PPFD) were measured at the nodes of the measured mesh. The tests were made for two cylindrical LEDs in designed photobioreactors. The measurements were made during the culture inside the culture medium using a Quantum MQ-200 Apogee Instruments Quantum Digital Meter. The tests were performed for the different intensity of light, light colour and the length of exposure time. Preliminary lighting studies have spearheaded the first stage of the modeling and lighting optimization process in the designed photobioreactors. They allowed the following conclusions: No statistically significant differences were found between the instantaneous intensity of PAR radiation for the analyzed photobioreactors, The increase in biomass of alga results in a change in the intensity distribution of photosynthetic active radiation PAR in photobioreactors, The increase in optical density in the photobioreactor causes a decrease in light intensity within the reactor.
