Characterization of horticulture and general lighting-LEDs and Luminaires

Abstract

There is a surge in the number of young growers. Artificial light sources are used to grow various plant species. The availability of horticulture LED light sources when compared to the general lighting LED sources in the market is small in number. In this paper, an experimental investigation of the electrical and optical characteristics of both types of LEDs was conducted and analyzed. The measurements were made under room temperature and typical drive current. Further, electrical-optical characteristics of horticulture and general lighting luminaires were measured and analyzed. The results indicated that the light output level and R:B ratio of the luminaires vary significantly.
