Development of multi-colored LED system for therapeutic application


BACKGROUND: The evaluation and control of lighting is crucial in physiological, biomedical, and industrial fields. Many kinds of lighting techniques based on LED have been developed due to its advantages.

OBJECTIVE: The aim of this study is to develop the multi-colored LED system for healing purposes.

METHODS: Light source with three-color chip LEDs was investigated to detect the dominant wavelength.

RESULTS: The results show that the additive principle by three-color LEDs can be successfully applied to lighting system by generating a variety of colors.

CONCLUSIONS: The results are expected to be useful in the field of light therapy and medicine. Applications of the developed light system are lighting therapies such as stimulating blood circulation and digestive processes, and controlling inflammation.
