The purpose of this work was to examine which LED fungal treatment device can be applied to the face. Several methods were used for that purpose. More specifically, 240 50mA low-power LED chips were selected. As a result, a light distribution angle of 150 degrees was possible, and the temperature could be adjusted in the range of 27-32 degrees for fungal treatment (acne), making the device suitable for use. The results show that face use possible factor is more common than initially expected.

... reover, further investigation of the decreases in the angle for standardization of the temperature is required. The simulation is performed by the Multi-physics of COMSOL after designating the features of the aluminum heat insulation plate and the indoor air at the temperature of 20°C for the heat analysis with the features of density=1.127kg/㎥, thermal conductivity= 0.027W/m▪K, and specific heat=1,005J/Kg▪㎥.
