SPONTANEOUS EMISSION TYPE LIGHT-CONVERSION MATERIAL FOR LIGHT THERAPY, AND FUNCTIONAL PATCH AND FUNCTIONAL MASK PACK COMPRISING SAME

摘要

The present invention relates to a spontaneous emission type light-conversion material for light therapy, which outputs a specific wavelength, and a functional patch and a functional mask pack comprising same. More particularly, the present invention relates to a light-conversion material, and a functional patch and a functional mask pack comprising same and thus having a light therapy function, wherein, on the basis of a principle that, in order to perform a light therapy function, sunlight and ambient light are absorbed to emit light (in a quasi-spontaneous emission type), a sapphire-based blue phosphorescent phosphor material is used as a core which is an eco-friendly energy source, and which has a relatively long light emitting time, so as to excite light, and a shell part is configured such that, by selecting the wavelength, excited light can be absorbed to emit light. The material is thus designed in a complex structure in which the wavelength can be selected to efficiently exhibit the light therapy function.
