First, referring to fig. 1 to 3, a laundry treating apparatus of the present invention will be described. As shown in fig. 1 to 3, in order to solve the problem that the external power source is difficult to be arranged inside the conventional drum washing machine due to the rotation of the inner drum, the laundry treating apparatus of the present invention includes a rotary tub 1, the rotary tub 1 having a hollow protrusion 11, a first sealing housing 2 fixed inside the hollow protrusion 11, a light emitting lamp 3 fixed on the top of the first sealing housing 2, and a power supply module 4 disposed inside the first sealing housing 2, the top of the first sealing housing 2 passing through the hollow protrusion 11 so that the light emitting lamp 3 can be irradiated into the inside of the rotary tub 1, the power supply module 4 being electrically connected to the light emitting lamp 3, the power supply module 4 being configured to generate electric energy based on the rotation or vibration of the rotary tub 1 and then supply power to the light emitting lamp 3.
