植物工場用光源におけるLEDの優位性

摘要

Visible light between 400 and 700 nm is active for photosynthesis, and general lighting source can be substitution of the light for plant factory. Many kinds of method to obtain the multi-color lighting source are proposed. In those method components, the combination of blue LED and phosphor excited with blue emission is most effective. It is difficult to improve the efficiency of LED light source, so new ideas are expected and it is necessary to understand the phenomena of the relation between plants and light irradiation.
