An object of the present invention is to provide a light emitting diode (LED), a laser diode, etc. based on a wearable (wearable) for patch-type ultra-small phototherapy device for skin disease treatment. Accordingly, in the present invention, a light emitting device and a pair of left and right first metal electrodes (+ poles) are formed on the upper surface, and the second metal electrode is formed on the lower surface of the PCB substrate; a battery in which the first electrode on the upper surface is in contact with the second metal electrode on the lower surface of the PCB substrate and the second electrode on the lower surface; and the battery is inserted therein, the PCB substrate is slidably inserted in the front-back direction, and the lower inner side is in contact with the second electrode of the battery according to the sliding insertion position of the PCB substrate, and the upper inner side is the PCB Disclosed is a miniature phototherapy device for treating skin diseases including an electrode body selectively in contact with a first metal electrode of a substrate to supply or cut off power of the battery to the PCB substrate. |
