Abstract: An ultra-compact phototherapy apparatus for treating skin diseases includes: a PCB substrate in which a light emitting element and a pair of left and right first metal electrodes (positive pole) are formed on an upper surface and a second metal electrode is formed on a lower surface, a battery having a first electrode on an upper surface, which is in contact with the second metal electrode on the lower surface of the PCB substrate, and a second electrode on a lower surface, and an electrode body formed so that the battery is inserted inside and the PCB substrate is inserted in slidingly a front-rear direction, of which an upper inner side is selectively in contact with the first metal electrode of the PCB substrate.

Abstract: A light therapy device, including: a housing including a hanging part lying over a user's nose and a bridge part connected to the hanging part; a light source positioned inside the housing and emitting light for treatment; and a rhinitis treatment optical guide having a protruding shape inside the housing to be inserted into the user's nose and guiding the light emitted from the light source to the outside.
