RADIANT ENERGY IRRADIATION DEVICE

摘要

A radiant energy irradiation device is provided with a means for irradiating an illuminating light containing radiation in a visible wavelength region and radiation in a specified wavelength region (for example, in the range of 600 to 1100 nm) that penetrates into a living body to maintain and promote biological functions. Radiation in this specified wavelength region can strengthen a biological immunity, activates an autonomic nerve system and maintain and promote biological functions. A radiation means for radiation in a visible wavelength region and a radiation means for radiation in a specified wavelength region may be integrated together or at least one of the two means may be independently provided.
